How powerful a bandsaw motor is powerful enough?
I am contemplating replacing my 14" bandsaw and tablesaw with a bigger
bandsaw. I think I have a handle on the good and bad points of that scheme. (but if you have any profound insights...) My 14" is 1hp and certainly wouldn't rip fast enough to replace a TS. The bigger ones are 2hp up to 5hp. How big do I have to go before it will rip 4/4 oak satisfactorily? (sure, I cut 8/4 ocassionally, but not often enough to worry about it.) I would prefer to keep it on a 20a circuit, but can certainly put in a 30a circuit if 3hp won't cut it. |

Band saws are wonderful tools for cutting crooked edges in wood. Table saws
are wonderfull for cutting straight edges in wood. While you can do either on either saw each has it's best use. If you want to get straight edges with a band saw you will need a lot of skill or a planner and jointer to help out. Your best bet IMO is to make room to upgrade the TS or get a RAS and learn to use it. "Toller" wrote in message ... I am contemplating replacing my 14" bandsaw and tablesaw with a bigger bandsaw.

I have a severe space problem. No room to upgrade the TS. My hope is to upgrade the BS and get rid of the TS. I'll bet you have plenty of room you just haven't considered yet. A tablesaw wouldn't take up any more room than that big table and all those chairs in your dining room. Or you could just move the sofa out and put it there. You just have to get your priorities straight. Once you do that, you'll find the room. DonkeyHody "The cheapest things in life are free." |

If you can't rip 4/4 or even 8/4 as fast as you can control it with a one horse, you're going to want a real monster. Better to consider your saw by the width of blade it will tension than the ponies in the bottom. That's where the accuracy comes in. Get something in the 18-24 range that will take a fairly thick 1" or better blade, and if there's an option, you can go for the higher rated motor. 20A (actually ~10 continuous) @ 230 will haul a couple horse easy, which is about the upper limit for single belt, so I'd look for double or ribbed. Keep your tablesaw. You can maneuver everything you're using the bandsaw for over that top, and everyone needs a good flat assembly area. |

Now some motors are more or less efficient; my 2hp TS motor only draws 17a, but it was 50% more expensive than the same manufacturer's 20a 2hp motor. |

The blade seems to be a much bigger factor. Carbon steel blades dull very quickly and dull blades cut slowly. I noticed a huge improvement when I moved to bi-metal blades. Mark |

Horsepower per se shouldn't make a difference in cutting speed--it's the blade speed and the blade design that decide that. As long as there's enough power to keep the blade going at full speed at the feed rate that you're using there's no advantage to be gained by more power. How fast is it cutting, i.e. how many seconds does it take you to go through a foot of 4/4 oak? First thing to check--is your saw a single-speed saw or does it have more than one speed? If it's not single-speed then make sure it's on its highest blade speed--if it's not that would cause it to cut slowly. Next thing, what kind of blade do you have in it? A blade designed for resawing thick lumber will cut more slowly on thin lumber than one that was designed for that purpose. The blades that come in bandsaws are usually pieces of crap. Every once in a while you may find a good one but don't count on it. -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

Well, yeah, but have you _priced_ a 24" Powermatic? ;-) That's one serious wooddorking tool. The choice of tools in your shop is up to you, and your checkbook, and those who also have some claim on your checkbook. I've come to the conclusion that, for now, I'll find a way to do without a big bandsaw. I miss it, though. Good luck on the gloat finding. Patriarch |

Perhaps you might want to upgrade the motor on your present 14"
bandsaw? A question for the group...what is the largest HP motor that can be reasonably mounted on a 14" bandsaw (like a Delta)? Would it matter if it were a wood or wood/metal version of the saw? Maybe a 3 phase with VFD so you would have a variable speed saw? TMT Toller wrote: I am contemplating replacing my 14" bandsaw and tablesaw with a bigger bandsaw.

Cross cutting, roughing out lap joints, making tenons. Very very rarely I might rip a weathergroove or do something like that. Mitres are a little tricky cause the forces on the blade tends to deflect the angle on the arm, but then I expect something similar to happen on tablesaws. -P. -- ========================================= firstname dot lastname at gmail fullstop com |

What kind of blade does the HS have and what kind do you have (material, width, tooth pattern and tpi)? I still think that the blade may be the main difference. If the blades wanders back and forth as you cut, then it is dull. You can watch that happen as you push the wood through the blade. Also, I have found that if you have some kind of misalignment in the board, fence, or table that will cause the board to bind the blade, that it will be significantly harder to push. I have definitely experienced that when resawing, but I don't think I have ever experienced that with 4/4 stock. Mark |

I still think that the blade may be the main difference. Well, guides are more important than teeth in controlling wander, unless someone's dinged the right-set side. It's overall stiffness that counts here, as elsewhere. The tension, thickness of the blade, the width and the guides all go toward making it a saw rather than a floppy piece of metal being dragged through the board. Within limits, as we know, slowing the feed will allow rotational inertia from a 1/2 horse to cut 6" deep. Did it for years on the old Sears saw. Took a while, though. Wet wood for turning stock could be a real nightmare, but it's no pleasure on the current Delta and one horse, either. |

OTOH I don't need to pay rent on the space, I don't have capital tied up in the vast range of stock, and best of all there's a a guy there with a lovely plywood panel saw who can cut anything I want to any size I want. If it's a cut simple enough that I can describe it over the phone, I just have them do it before I pick it up. Tomorrow morning I need to pick up a sheet ripped into 16" strips. I could have ripped this down myself, but I'd need to tidy the workshop first to fit an 8x4 through the cabinet saw, and borrow a friend to help carry it. Having the supplier (Avon Plywood) do it for me instead saves me a _lot_ of time and trouble, and the extra cost of cutting charges would barely pay the extra tea bill of having assistants over to help out. The only place near me that sells furniture grade plywood charges $3/cut. I have to get at least one to get it home, but hurts to pay for something I could do myself. I really have to get over that, don't I? |
