Accurate cross cuts
What is the best piece of equipment to use (and who makes it) to obtain
accurate cross cuts? I have a Sears radial arm saw and it seems like I spend all my time adjusting it. Any recommendations would be appreciated. |

The problem you describe has been discussed on this forum many times before and, seemingly, is common to radial arm saws and in particular the Sears(a.k.a. Crapsman) saw. I had a Cman RAS and finally gave it away to Habitat for Humanity out of frustration and need for space. I realize that none of my remarks are of much help. Larry |

Any recommendations would be appreciated. Are you asking how to use your RAS better or for recommendations for new equipment? I have a 25 year old Sears RAS and it stays in adjustment quite satisfactorily as long as I change in in the bevel and miter modes. If I switch to rip mode or move the motor in the vertical mode for surface planing, then I have to at least check the alignment when I go back to cross cut mode. The big advantage of a radial arm saw is its flexibility, but you pay for this in terms of more frequent adjustments. If you are looking for recommendations that involve other equipment, then I would suggest a miter saw (chop saw) dedicated to cross cutting smaller width pieces or a table saw with a cross cut sled. If you work with large width pieces, then you might invest in a panel saw. |

I too have RAS, made by Ridgid. My complaint is not flexing, but the fact
there is no indexing of the arm at any angle, much less 90 degrees. The only way to really set it is to use a framing square off the fence, and then do a crosscut on a broad piece of wood, flipping it over to see if the gap is closed on the cut. A hassle, don't like it, but dealing with it..Otherwise, I like the flexibility of cuts you can make.. "Steve Radoci" wrote in message ...

Any recommendations would be appreciated. If you have an accurate square, you already have all the equipment you need. NOTE: if your square also came from Sears, you do not have an accurate square. Accurate squares come from specialty dealers catering to woodworkers or machinists. Starrett is a particularly good brand. A bit pricy, but worth it. You can make accurate, repeatable 90-degree crosscuts with this saw, provided that you (a) take the time to align it dead-on to 90 degrees using an accurate square, (b) have a good straight, flat, and smooth fence board, (c) never budge it off of 90 degrees once you have it set up (or take the time to realign it to 90 after you change the angle), and (d) check periodically to make sure it's still square. It is not possible to accurately set *both* the 45- and 90-degree stops on this saw. Setting one of them accurately misaligns the other by a fraction of a degree. Another option is a good-quality table saw (these also don't come from Sears), and a precision miter gauge for it, such as one of the Incra miter gauges (www.incra.com). I have an Incra 2000 that I'd be willing to sell, so that I can buy an Incra 3000; if you're interested, email me at the address shown in my sig line and we can talk about it. -- Regards, Doug Miller (alphageek-at-milmac-dot-com) |

Make various jigs, that index off the fence, for the angles you require and keep the saw at 90 degrees. -- Jack Novak ================================================== ======== Yep.... my old (60's..Crapsman) has not moved off 90 degrees in 30 years Actually I have very little problems with keeping it "dead on"... I still haul out the sled for the table saw however when I need a perfect cut....I use the RAS for rough cuts when 89.9 degrees is close enough... lol The key is never swing the arm.... Bob G |

I'll say this, I may have had some questionable electric tools from Sears, I have never had much reason to curse a hand tool I got from them. Square is easy, draw a line, flip the square and draw another line, if they are parallel then it is square if they converge then they are not... This is sufficient to demonstrate approximate squareness, but is not sufficiently precise to determine a truly accurate square. Or take a small machinist square with you and use it to check them, but I can't imagine that would work any better. Actually, that will work a *lot* better. You need a machinist's square of known precision, a straightedge also of known precision to base them against, and a set of feeler gauges to measure the deviation between them. Come to think of it, I would think there were some neanders here that have built countless of their own squares which I'm sure they will also claim to be dead on... Oh, no, not *that* debate again (Strickland vs. Bennett). -- Regards, Doug Miller (alphageek-at-milmac-dot-com) |

Accurate cross cuts
I have two 12" combination squares, a Starrett that I use for woodworking, and a Sears that I use for rough carpentry. The Starrett is square +/- 0.001" over its entire length (90 degrees +/- 17 arc-seconds). The Sears deviates from the Starret by 0.011" along its length (90 degrees +/- 3 minutes 9 seconds). For anyone keeping score at home, 99.9% of normal people use a speed square for rough carpentry since they don't want to bang up their combo square in a rough carpentry environment. A marking pencil or knife is going to be significantly thicker than .001 rendering that sort of accuracy useless for woodworking. Additionally, unless you're using a robotic arm to mark, the line is going to waiver as your arm moves the knife or pencil. You can also add in blade deflection, wood movement, etc. and figure out that .001 accuracy is complete overkill in woodworking. So get the cool .00000001 accurate tools if you want but please don't think that they're going to do any better for you than a .01 tool. |

come to think of it, I rarely mark a piece with pencil. I cut all
similar pieces (crosscuts OR rips) with the fence set on the TS. For crosscuts, I use a 1" thick aux fence as a stop when using the sled. No fiddling around with a square or pencil. that's a time waster and completely unnecessary to get accurate 90 degree crosscuts. dave Steve wrote: I have two 12" combination squares, a Starrett that I use for woodworking, and a Sears that I use for rough carpentry.

if you are talking setting up the equipment, I agree that AFFORDABLE
accuracy is imperative to excellent woodworking results. Rather than spring for Starrett stuff, I check the squares for reasonable accuracy. The one I picked up at a WW show last year is fine. The framing square I've had for years is a joke. It would work for rough-in, but that's about it. BTW, I DO have one Starrett product: a digital tape. Now that's a contradiction. If you use the digital readout, accuracy is worse than 1/64, at best! dave Doug Miller wrote: In article om, Bay Area Dave wrote: FINALLY! the voice of reason. well said, Steve dave Steve wrote: I have two 12" combination squares, a Starrett that I use for woodworking, and a Sears that I use for rough carpentry.

If you think this is "hogwash" then you've never had your hands on an accurate square -- or else your definition of "accurate" differs considerably from mine. I do NOT consider 89.95 or 90.05 degrees to be accurate. Maybe you do. But that is about the best you're going to get from Sears. I consider it accurate if I get an accurate cut across the entire length of the work area...usually 8 to 12 ft. for most of my work. What device are you using?...to discover that a square is off .05 degrees? lol Feeler gauges to determine deviation. Quick mental calculation to determine deviation per unit length. Calculator to convert deviation per unit length to deviation in fractional degrees. It's simple trigonometry. And are you drawing that 'square' line with an 8' for 12' square? Or are you putting another fallible scribing tool on the work to finish the line? As I mentioned in another post, I'm using the square to align my table saw, jointer, and radial arm saw. I never mentioned using it to scribe lines, and in fact I don't do that. I've got several different kinds of squares...none that I paid more than $20 for...and they're all dead-on. They can easily be checked for accuracy before you purchase them. "Dead on" means no measurable deviation. Correct...by a 'measuring' device'. Unless you're using precision measuring instuments (e.g. a dial indicator, or a set of feeler gauges), you have no basis for making that claim. Making a pencil mark, flipping the square over, and making another pencil mark is sufficient to demonstrate approximate squareness (+/- 0.05 to 0.1 degrees), but is insufficient to support the claim of "dead-on" accuracy. I meant 'dead-on' for my purposes, of course. Why would you think I meant differently? Then you're using terminology incorrectly. Dead-on is an absolute term, not a relative one. There is no such thing as "dead-on for your purposes". It's either dead-on, or it's not. What you meant was it's close enough for your purposes. And I have no quarrel with it, stated that way. How far off do you think the bubble on a LEVEL is? lol Irrelevant. Its all relative. If you think a line drawn with a square should be dead-on...meaning NO deviation whatsoever...then I have never had a proper square. And I don't think you have, either. Quite so. I *do* have one that's accurate to +/- 0.001", though. You don't. And one is from Sears. Either your definition of "accurate" is *very* different from mine, or you don't know how to measure it. Obviously, its very different. I have two 12" combination squares, a Starrett that I use for woodworking, and a Sears that I use for rough carpentry. The Starrett is square +/- 0.001" over its entire length (90 degrees +/- 17 arc-seconds). The Sears deviates from the Starret by 0.011" along its length (90 degrees +/- 3 minutes 9 seconds). Hardly accurate across 100 ft. But just as accurate as any of mine...for woodworking. No, it's not. Align your table saw with your square. Then use that square to set your miter gauge at 45 degrees. Now cut a mitered frame, say 30 by 38 inches (which happens to be the size of my living room coffee table). Assemble the frame. Then measure the gaps at the joints. Maybe you're happy with what you see. When I do this, the joints have no visible gaps, and a 0.002" feeler gauge (the thinnest I have) cannot be inserted. By *my* definition, the Sears tool is not accurate. Perhaps by your definition it is. Yes...it is. If it's good enough for you, fine. But don't claim that it's "dead-on" when you understand neither what the term means, nor how to measure it. Even most of the $2.95 framing squares are dead-on accurate nowadays. Speaking of hogwash...!! You say three-dollar framing squares are "dead-on accurate". I say, prove it. Compare one against a square of known accuracy (e.g. a 24" Starrett), and measure the deviation with feeler gauges. Then post your results. I've got several 'squares' that I've built...2'x4'...2'x8'...etc...that are 'dead-on'...for what I want to do. "Good enough" is *not* the same as "dead on". -- Regards, Doug Miller (alphageek-at-milmac-dot-com) |

For those of us just getting up to speed, would you care to explain the
best way to check the squareness of a square? I've always heard the thing about putting it up against a straight flat edge of wood, whether jointed or a sheet good factory edge, and draw one line, and then flip the square over and draw a second line parallel to the first, and then measure the difference (hopefully none). Most of my squares, whether carpentry, try, or large/small combo squares seem reasonable on by this method (I have a framing square that needs adjusted, it seems), but I question how accurate the method is, especially w/ that little 6" combo square (not a very long line to pick up error on). Any suggestions would be helpful. Thanks, nuk -- I know more than enough *nix to do some very destructive things, and not nearly enough to do very many useful things. |

No, if you have a cylindrical grinder and are really pretty good using it,
you can make a reference square to a few tenths per foot. You'd be a pretty long time getting that on a lathe, and it would be by luck not skill in the end.

You must guarantee the squareness of the square when you purchase the damn
thing yourself. Jeez! Tom |

I agree that it would be nice to have them coming in some kind of hardwood instrument type case, since thats basically what they are. I found this on Amazon (about the only negative comment I could find on the 12" combo square): snip I'll admit, that I was a bit disappointed by the fact that it was shipped in a plain cardboard box, and not a more permanent storage container. snip So it doesn't seem like they come w/ much in the way of protection from the manufacturer. But I'd hazard a guess that since about every good mechanic and machinist I've ever come in contact w/ swears by Starrett and considers them basically a 'gold' standard, that the tools aren't *that* easy to mess up, whether due to simple design, close tolerances, or quality materials. I recall a fellow a while back here on the Wreck saying that he'd been having issues w/ Starrett over the last few years, and preferred a different (even more expensive!) brand, but he worked in a metrology (i.e. calibration) shop and I'd guess is a little more picky than I am Haven't heard any complaints otherwise, but then, I guess most people aren't equipped or qualified to make those kind of evaluations... nuk -- I know more than enough *nix to do some very destructive things, and not nearly enough to do very many useful things. |

The companies that sell precision tools (Starrett, Mititoyo, ect) know about
shipping and do pack their tools appropriately. To the distributor. It is up to the distributor to get it to you. Your best bet for precision tools is to buy from a tool supplier such as Rutland Tool, Travers, ect. They deal with this stuff for a living and do pack appropriately. The woodworking tool places may not, though I would bet that most do pretty well. In any case, go to a real tool suplier for precision tools. Not only do they have a better selection, they often have better prices. When I was first starting out (as a machinist), I lived in a place that no precision tools were available. Everything was mail order. I dealt with the big tool suppliers. Never had anything damaged in shipping. "Silvan" wrote in message ...

I remember that post and I agree with him. The subject was dial calipers and
he prefered Mititoyo over Starrett. The Starrett required repair far more often than Mititoyo. This has also been my experience. Some of Starretts tools are quite good. Some I wouldn't touch. Just like any other tool manufacturer, they do some things well and others not so well. "nuk" wrote in message ...

No need to get snotty about it. But while we're at it, lets see: a few years back, in the U.S. Navy Nuclear Propulsion Program, the dial indicators and micrometers and calipers and about every other mechanical measuring device I came in contact w/ was Starrett (disclaimer: I was a sub nuke electrician). Don't remember using anything else. Just like we used Fluke for the multimeters, Techtronics for the oscilloscopes, etc. There *might* be other equipment that could be arguably better, but generally speaking, if there was, I'd be surprised they weren't using it. Military contracts or not. Picky doesn't even *begin* to describe the attitude towards tools and procedures in that program. Then when I got out, in the (big) steel mill in Kansas City I worked in, the millwrights and machinists and motor rebuild shops used, thats right, Starrett. I went from there to a civilian nuke plant for a brief time, and the stuff in the electrical maint. shop at least was Starrett and some Mitutoyo. Now I work at a hydro power plant, and a brief tour thru the tool room reveals an awful lot of Starrett stuff, and again, some Mitutoyo. A friend of mine is a fairly skilled machinist who used to work at LE Wilson Tool & Die here in central Washington. Since most people don't know that name, they make custom dies for centerfire rifle competition shooters, of whom many are machinists, mechanics, engineers, or other picky sorts. Take a wild guess at what he used there, and still uses for instruments: Starrett. Most of the shooters have a small amount invested in calipers, either dial or digital, micrometers, and dial indicators, and when people step up from the $20 steel calipers from RCBS, or $50 mikes from Midway, they go either Mitutoyo or Starrett. In a sport where its not uncommon for people to have $3k plus tied up in just the gun, be it Benchrest or HighPower, if there was something significantly 'better', I think it'd be selling like hotcakes. Not knocking Brown and Sharpe, but the above is why when someone mentioned Starrett slipping and Brown and Sharpe being 'better', my initial response was 'Brown and who?!?' Now, I might be barking up the wrong tree here, and maybe B&S does make some product that is better than a comparable product from Starrett. That's entirely possible. But please don't go making assumptions about the machinists and mechanics I know. They might take it wrong In any event, I'm working at getting some better tools myself, and it may come down to the same thing that resulted in me getting Mitutoyo digital calipers and micrometers instead of Starrett: For my uses, they are accurate *enough*. I most likely wouldn't notice the difference btwn Mitutoyo, Starret, or Brown & Sharpe for what I'm doing. Anyway, time to get off the soap box. Have a nice night nuk -- I know more than enough *nix to do some very destructive things, and not nearly enough to do very many useful things. |

So 'square' for YOUR work is all that is necessary. If the blade is strait and it is out of square at any distance, it is out of square at all distances. It just becomes more obvious at longer distances. I make things square for MY projects...usually spanning 8 to 12 ft. And I've built some wooden, quick squares precisely for this...2', 4', 6' in length, etc. These are dead-on...for my uses. If you set up a square...and draw a line 10,000 miles long...lol...its not gonna be square at the end of that line. But it may be perfectly square at 4 ft. So its also relative. No it won't. See above. IMHO, a combo square is one of the least accurate tools you can buy. I've never seen one yet that doesn't have at least a little play in them. Quit buying those Chinese squares. Try a Starrett or Mititoyo. You'll change your mind. |
