Ebay has plans for bid http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW I've seen the second one, not too hard to follow.

I'd like to build one of the bandsawmills. And I've been
thinking about how you might design the mounts for the bandsaw wheels. If you have the two wheel axels under tension, what type of bearing is best/standard/normal for this type of application? I was thinking that a roller or ball bearing wouldn't be quite right for this sort of thing. But I don't know much about bearings, or bearing terminology. And second, I was thinking that one wheel could be fixed, while the other one would need atleast the tension adjustment. But is this true or a good idea, because you might need to adjust each wheel to keep the band from jumping off. I was thinking that an excellent way to begin to mount these wheels would be to take a solid bar and put it on a vertical mill and make both axel sides as accurate as you could get it, with some sort of slide provision for the tension adjustment. But then I thought maybe this would be wasted effort because the wheels might not be available to take advantage of this precision. IE. Can you get super balanced, super true wheels? Thanks. |

I've been scrouning parts for a bandmill for a while, there's a group on yahoo for milling (lumber). I've picked up an old front wheel drive car and plan on using the rear axle parts for the band wheels. Some plans specify a trailer axle set, cast wheels would be ideal but more than I want to invest. The mini spare tires are said to work nice in this application. I've been hoping for steel prices to come down a bit before I start. I'm going to use hydraulics for tensioners, feed ect. I want to use a 20hp 3ph electric motor for power. And second, I was thinking that one wheel could be fixed, while the other one would need atleast the tension adjustment. But is this true or a good idea, because you might need to adjust each wheel to keep the band from jumping off. The tracking adjustment is simular to a standard shop bandsaw. A 1.25" blades needs a* lot* of tension . My main concern is to operate remotely away from the blade, non of this pushing the carriage by hand for me. I was thinking that an excellent way to begin to mount these wheels would be to take a solid bar and put it on a vertical mill and make both axel sides as accurate as you could get it, with some sort of slide provision for the tension adjustment. Use tele tubing with roller bearings for guides. The plans on ebay are worth looking at along with some of the web sites. A lathe/mill would be very helpfull. But then I thought maybe this would be wasted effort because the wheels might not be available to take advantage of this precision. IE. Can you get super balanced, super true wheels? Yep, cast wheels are available from some of the manufactures also used mills are sometimes cheaper than building a mill.

I saw pictures of a well used home made bandsaw mill. The drive wheels were actually drive tires. Yup, regular car wheels, with inflated tires on 'em. It looked as if the wheels were mounted to axles and axle housings that had been cut down. It was a pretty big setup in that it could handle large diameter trees. I'm sure it's still out there on the web. ERS |

b I'm
going to use hydraulics for tensioners, feed ect. I want to use a 20hp 3ph electric motor for power. /b Are you going to use the motor to power a hydraulic system then use hydraulic motors to sping the band and move the carriage? (keep me filled in on this, if you are) I hear you about staying away from the thing. I'm also going to put a fairly hefty cowling around the thing, a balistic shield. I thought maybe I would pony up for the wheels and build everything else. Go price your steel. I needed some the other day, and was expecting something outrageous, but the total wasn't that bad. Shop around. Finished goods made from steel warped my expectations a little bit for the raw metal. Things made from steel sure have skyrocketed. |

Just bolt a CV axle thru the assy cut off the other CV joint and attach a pulley or two for the drive. I'm leaving some of the obvious items like pillow blocks to support the cv axle but by using one cv joint it will allow you to shim the spindle assy's without binding up the drive shaft. Those spindle assy's cost around 60 bucks new in KY and a new CV axle costs 75 bucks. Good luck. |

If it would handle the tension required to keep a 1.25+" blade tensioned and be power fed into a log I'd say nothing. Well, I have a resaw blade for it, and it handles 6" of wood in resaw just fine, so that's nearly there for logs. I want hydraulic tension for a couple of reasons and that would require some mass to stand up to the higher tensions. The longer the blade the sharper it stays. Makes sense - less passes per tooth, when there are more teeth. If you are sawing along and hit a hard spot heating up the blade it will expand and I want something to keep the tension on the blade. That would be either a big spring or hydraulic. The big spring is already on a bandsaw, so ... ??? I have to agree about the fiddly part, a friend had a cabin done by a man with a bandmill --top of the line with all the goodies. It did some great work and fast but a 40k investment in the saw alone. I don't use that much lumber to justify that sort of thing, but if I can do this for 500 bucks plus the saw I already have, then it's attractive. Doubly so if I can make the saw a temporary member of the sawmill, and bring it back into the shop when I'm done. Also know a fellow who built a cabin with a chain saw mill---talk about detemined, said he wouldn't do it again. I've seen chainsaw mills used, and I'd tend to agree. Maybe for the challenge, but not as a routine. Too much kerf loss if nothing else. |

I always see this mentioned in regard to chainsaw mills, "too much kerf loss" and I guess compared to a band saw mill, it does chew out a wider cut, but have you ever seen one of those old Bell-Saw circular saw rigs? The kerf on those runs as bad if not worse than a chainsaw mill! If it gets the job done and you are not paying for the trees, a chain saw mill is the cheapest solution. If you are talking about production work, then even the lower end bandsaw mills could be called "too much work" |

It's way out of the ballpark. The mills are designed to tear through large quantities of wood, mlaybe up to 12" or more, at high speed. This is a point. The Delta simply could not take the tensionming of the 1.25" band This is true. IIRC, the largest blade the Delta 14" was designed for was a 3/4" one. Getting a proper tension on a wider one would be nearly impossible...although I do seem to remember hearing about some low tension blades out there... Hm... the resaw blade I have is I think a 1" band, does good on smaller stuff. Do you suppose it's a "won't work", or a "would be slow" kind of situation? I have had really good luck with using my Delta 14" for resawing lumber, and, for preparing bowl blanks for the lathe. It is a bit slower than some other machines...but, then...I am not trying to make a profit here. There is a big difference between hobby milling and milling for profit. If I was going to go into the small-scale sawmill business, I suspect I would just go ahead and drop the cash for a small commercial mill. After all, my goal would be to make money off sawing wood...NOT to burn a lot of expensive time building a kit. my problems with using a 14" bandsaw for any serious milling are as follows: 1) unless serious surgery is done, 12" is the biggest chunk of wood that will feed through it. That is pretty small for lumber. If you do the surgery to build a frame to hold the two parts of the saw in sufficiently rigid alignment, then, you will have done so much work that you might as well have spent the extra 20 minutes to cobble together the mounting plates for a couple of car tires for the band to run on. 2) awkwardness. That Delta is cast iron...and pretty heavy, so getting it mounted would be an issue. 3) As a part of that...it is DESIGNED to be used upright. While I have seen a few mills that cut with the band vertical, most of the smaller, hobby mills run the band horizontal. Mounting it vertically means that there is a lot of work to raise the log up to it. Mounting it horizontally means that it MAY not be rigid enough to withstand both the force of gravity AND the tension of the blade, so, might well be hard to align. 4) To get the full benefit of the blade, one would really have to remove the table and rework the guide mechanism...not only is that more work, but, it means that the saw becomes useless for anything BUT sawing logs. realistically, it is unlikely that anyone would take the 30 minutes to an hour or more to get the removed parts remounted and the saw set up for other uses around the shop. Now, having said all that...I think that by building an infeed and outfeed table that provide good support for a log carrier, it would be quite possible to use the saw for SMALL sawmill projects. Frankly, I find that with the WoodSlicer blade from Highland Hardware, I can feed a full, 6" board through the saw pretty much as fast as I like without bogging the saw down (I have a 3/4 HP motor on my saw, too), so, I suspect that with a manual saw like this, it should be "fast enough" for hobby work.

Do you suppose it's a "won't work", or a "would be slow" kind of situation? Dave, A good way to look at this is in the horsepower ratings. My 12" shop bandsaw is a .75hp A 14" delta can't be much more than that. 10 hp on a bandmill would be underpowered, 14-20 is more like it. It's not just the wheel size but the axle/bearings on the wheels not to mention the guides needed for highspeed sawing. Size matters.... Are the pulleys on the delta rated to handle 20+hp? My chainsaw mill is 12hp 36" bar and it will rough mill a log into cabinet wood fast. I resaw on the bandsaw in the shop after drying. Making a homemade carriage with the wheels aligned and coplanier is not brain surgery, just basic setup work in a mill with the adjuster doing the final tracking. For me the hydraulic engineering is the tough part ie making it somewhat automated.

I don;t have any problems resawing on my homebuilt 20" bandsaw with a
1" blade. Works fine for what little woodworking I use it for.......I built it to make metal chips not wood, but sometimes you just have to make those woodchips as well. ============================================== Put some color in your cheeks...garden naked! |

what does it mean to 'put a crown on the band wheel'?
Is this a hump in the middle or lips on the edge, or what? Thanks. |

The face of the wheel has a crown or "hump" as you say on it. Its to
help make the blade track. I have made any crowns I used from 1 1/2 deg to no more than 3 deg. It doesn't usually take much of a crown to get things to track.

Actually, the whole surface is curved such it is higher at the center than at the edges. You won't need much crown. The crown helps the blade to track. But aligning the wheels is way more important than crowning to get the saw band to track properly. The saw must be made so that at least one of the wheels is adjustable in two directions. Imagine a plane passing through the fixed wheel. Now imagine an in-and-out adjustment on the other wheel that lets you bring that wheel into the plane of the fixed wheel. And the other adjustment tilts the wheel. If a line is drawn through both wheel centers as they lay in the same plane the tilt axis will be parallel to the plane and perpendicular to the line passing through the wheel centers. And I think you will need a lip on the back sides of the wheels. At least all the band saws I've seen that used cast iron or steel wheels have a lip on the back to prevent the blade from coming off. And if the running surface of the wheels is wider than the distance from the bottom of the tooth roots to the back of the blade you will need a rubber belt (called a tire) on the wheels to prevent taking the set off one side of the teeth.

As a sawmill? Pretty near "won't work" Many reasons. Most of them have been said in replies to your post; power, position, tension, design, speed, max cut. But if you just had a little bit to do. I am surprised you can use a 1". Most of them are so thick they are not happy around a 14" wheel. I have seen some thinner ones. I think under heavy use, the 1" band of normal thickness may start to wear, as it's bent too small to be happy. Hm... the resaw blade I have is I think a 1" band, does good on smaller stuff.

I pointed out that a chainsaw mills kerf is not any wider than the old Bell-Saw traditional circular saw blade mill.

Secondly in regard to the criticism of a chainsaw mill being "too much work for production work", I would suggest that setting up the small, lower end (lower price) bandsaw mills, without the automatic or remote controls for return, depth of cut, etc. is ALSO a lot of work, similar to the work required for the set up of a chainsaw mill. Thus my statement that even a lower end bandsaw mill could be called "too much work". Yes, a small bandsaw portable mill may make a board cut faster than a chainsaw mill, but the real work is the set up and dragging the saw back for a second cut. Production work, (lots of board feet) requires a high end mill, which for most folks is way beyond their budgets, I know it is for me. a good bandsaw mill for production work, will run over $5,000, and more than likly, for real production work, you are in the over $10,000 range. When you compare a chainsaw mill setup which will usually run under $1,000, less if you already have a suitable saw, I don't think that a Chainsaw mill is such a bad deal. They are highly portable, relativly easy to sharpen, replace you cutting medium (chain) and they do get the job done. I find that the major work with making your own lumber is in the handling of the trees and then the proper stacking of the lumber, not so much in the cutting. With whatever method you choose, traditional circular sawmill, bandsaw mill, Portable or stationary, or chainsaw mill, you still have the back breaking work of moving the wood. Sorry for the long reply, but logging and milling wood IS hard work no matter what saw you choose to use. |

I agree that unless you are making/paying max $/weight for your wood, a chainsaw mill is no worse than a bs mill, and a lot cheaper on bang for the buck basis. I guess the only "work" difference might be pushing the chainsaw through the wood ( this is another aspect of wider kerf), and also the feeling I get that c/s chains take more care than BS blades to perform their job. However I base this on cutting clean wood with thye BS and bush wood with a C/S.

Production work, (lots of board feet) requires a high end mill, which for most folks is way beyond their budgets, I know it is for me. a good bandsaw mill for production work, will run over $5,000, and more than likly, for real production work, you are in the over $10,000 range. When you compare a chainsaw mill setup which will usually run under $1,000, less if you already have a suitable saw, I don't think that a Chainsaw mill is such a bad deal. They are highly portable, relativly easy to sharpen, replace you cutting medium (chain) and they do get the job done. I find that the major work with making your own lumber is in the handling of the trees and then the proper stacking of the lumber, not so much in the cutting. With whatever method you choose, traditional circular sawmill, bandsaw mill, Portable or stationary, or chainsaw mill, you still have the back breaking work of moving the wood. Sorry for the long reply, but logging and milling wood IS hard work no matter what saw you choose to use. |

Dave, A good way to look at this is in the horsepower ratings. My 12" shop bandsaw is a .75hp A 14" delta can't be much more than that. It's the dual-speed metal & wood Rockwell version from the 60's, and I seem to recall it was a bigger motor than that, but, ... 10 hp on a bandmill would be underpowered, 14-20 is more like it. Gotcha. It's not just the wheel size but the axle/bearings on the wheels not to mention the guides needed for highspeed sawing. Size matters.... Are the pulleys on the delta rated to handle 20+hp? Probably not. My chainsaw mill is 12hp 36" bar and it will rough mill a log into cabinet wood fast. I resaw on the bandsaw in the shop after drying. Making a homemade carriage with the wheels aligned and coplanier is not brain surgery, just basic setup work in a mill with the adjuster doing the final tracking. For me the hydraulic engineering is the tough part ie making it somewhat automated. Maybe _next_ summer. SWMBO informs me that a lawn in the "back yard" is the priority for this year. Anyone ever built a successful rock picker? |

I am not the original poster of this thread, I was just chiming in on the apparent bias against chainsaw mills, often being faulted for having too wide a kerf and being too work intensive.

In a previous life I landscaped my way through school each summer. I couldn't imagine making a rock picker for just a back yard. There are a number of different types of pickers, rakes, windrowers, basket types, agri use usually. There one made not far from here, very heavy duty 100+hp to run. The rental yards have one mounted on a skidsteer that works ok. How rocky is your yard? If not too bad just hire some young types and hand pick/rake it. In the real rocky stuff we didn't even try to pick rock we just hauled topsoil in and covered it up. Rock will move to the surface in the spring when the frost goes out if you live up north.

So, the harrow I'm using isn't far from it. Now that the rocks are tipped out of the soil, how do I pick 'em up? I was thinking some sort of a inclined ramp, with a metal edge at the front, and expanded steel mesh or similar as a "basket". Slight angle, rocks come in, dirt drops through, that sort of thing? googling for Degleman Rock Rake now, thanks! Dave "Free rocks, yours for the picking. I'm serious." Hinz |

The rental yards have one mounted on a skidsteer that works ok. How rocky is your yard? If not too bad just hire some young types and hand pick/rake it. We're talking an area 300 feet by 100 feet initially, and it's very rocky. I had parts of it clean last fall, and this spring I can't even see where I picked. It's a glacial "esker", so it's all the rocks it picked up from north of us, at the edge of the melt. In the real rocky stuff we didn't even try to pick rock we just hauled topsoil in and covered it up. Rock will move to the surface in the spring when the frost goes out if you live up north. Wisconsin. Yup, that's the thing. I can cover it with nice dirt, but they'll keep floating up. Maybe it's time to see what the rental place would charge. |

Rake them into piles and pick them up with the loader bucket. This was being used on airport work where any gravel with a bit of organic staining was reserved as "topsoil". The airport was situated on one of the finest gravel deposits in the country - everything from fine, white, silica sand, to one boulder 13 x 7 x 5 feet. Gerry :-)} London, Canada |

I'll see if I can find similar in Wisconsin, thanks. Unfortunately, the local implement dealer just closed... bought out by a larger outfit 2 or 3 years ago, and now it's empty. Funny how that works... |

If you'd like to try out that theory, Doug, I've got the perfect chunk of land for you to do it on. |
