Engineer's square
How do the Groz engineer's squares measure up for setting up a TS, BS, etc?
Rockler has them (set of 3) on sale for $29.99 instead of $39.99. I think the squares may also come in handy when installing a vise on my workbench to be (so I need a larget one for that?). A good graduated combination square would be useful too, no? If the engineers squares above were graduated I'd probably use them so much for general tasks that I'd end up messing them up/dropping them... At this point, I don't even have a good steel rule. Some of you have seen me around here long enough to know I am a beginner. What should I be collecting along these lines? Thanks, Bill P.S. Cleaned the (8') gutters today with a Sear ShopVac accessory ($19.99). Definitely a great tool for that chore! Since I recently had new roof installed, besides leaves they were full of grit and nails, etc. It blows leaves, cleans gutters, vacuums the car well. I never before got such satisfaction from a "vacuum cleaner"! : ) |

Thanks, Bill Bill, While the engineers squares at this price point are somewhat accurate, save your money and get a Starrett Try Square (~$75) and build a nice box for it. It is accurate enough (2 thou / 12") for anything you'll align in your shop or want to measure. It will also last you a lifetime and be a great tool to give to your grandson/daughter one of these days. (that's when the wheels on the walker are worn flat...;-) Bob S. |

I assume you mean "Reliable Try-Square, No. 61" (which is 6" in length). Getting-by with one would be just getting by, no? Starrett sure has a dizzying arrays of fine products (starret.com), and I thank you for introducing me to them. However, in view of the "big picture" I think I may be wise to buy the Groz squares (or similar) and put the leftover $ towards one of many other tools that I need. Well, who knows, maybe I'll find one on sale! : ) Bill |

An engineers square is usually quite stock-heavy. They're mostly useful for machine setup. A try square is better for laying out joinery. A good steel rule is accurate right out to each end, with easy to read markings. A 12" is nice, and a 6" comes in handy for smaller items. Some have markings on the end as well (useful for setting bit or blade height). The 6" Shinwa (at Lee Valley and other places) does a good job. A good combination square is useful. The Starrett or equivalent is expensive but nice. Another option would be to take a 45/45/90 plastic drafting triangle (generally very accurate) down to the big box store and test all the cheaper squares until you find one that happens to be accurate. Also check that the blade is straight. Chris |

I've found engineer squares quite useful for machine setup. I carry a 2" one in my shop apron for quick double-checks on various settings such as jointer fence, etc. I think the squares may also come in handy when installing a vise on my workbench to be (so I need a larget one for that?). Probably not so much. A good tri-square (combination square) would work better A good graduated combination square would be useful too, no? Probably would recommend one of them first or in combination with the engineers squares If the engineers squares above were graduated I'd probably use them so much for general tasks that I'd end up messing them up/dropping them... They wouldn't be engineers squares if they were graduated. Dropping them is definitely not a good thing. At this point, I don't even have a good steel rule.

Thanks, Bill IMO, the set of engineer squares, with a combination square, and a good straight-edge are a good start. -- There is never a situation where having more rounds is a disadvantage Rob Leatham |

While they are on the lower end of accuracy for squares used for setting up metal cutting tools, their precision goes beyond anything that is likely to be detectable in woodworking. Face it, there's nothing magic about machining two pieces of steel flat and sticking them together at right angles--they can do that as well in India or China as they do in the US and Japan and the EU. The place to spend the bucks is with a combination square--there the cheap ones usually aren't square out of the box and if they are they don't stay square very long--since they have moving parts, maintaining precision is more difficult than for something that is permanently welded/brazed. I finally spent the bucks for a Starrett and I'm glad I did. Browne & Sharpe and Mitutoyo also make good ones. |

A standard combo square is not that much more accurate IMHO unless you drop some serious coin, but they make a fine depth gauge as well. For tablesaw set up etc, a 6" machinist square does it all for me. If more than a couple of thou mess you up, use thicker glue. G |

A few years ago, long before I found this forum, I bought two carpenter's squares, 24" and 8", believing that I was starting my woodworking tool collection. I assume they may be good for deciding flatness and maybe cutting some square (replacement) pieces of drywall and as a replacement for a steel rule (?). I anticipated using them as a try square on wood, but from what I've read here they don't make the grade.. Does anyone here use carpenters squares for anything (besides stairways and roofs)? Probably precise enough to use on outdoor furniture, huh--or better than that? Bill |

If you're still not sure, buy the Groz, take it to your shop and see how much or if it's off square, and if that doesn't meet with your minimum requirements, take it back and tell them it's not square and step up to the Starett. |

You need to make sure that the edge you're referencing the square against is straight. If you're using a wooden surface, a knife will give a finer line than a pencil. If you've got a known-good square (a drafting triangle works fine) then take it and the one being tested and place them both facing each other against a known-straight edge. Hold it up against a light and see how big the gap (if any) is between the two blades. Chris |

If you wish to check that your TS blade is vertical, for instance, do you just use the base of the double square? It would appear that the base has the potential to have more "integrity" than the angle it forms with the rule. I like that it is graduated--seems very usable indeed.

If I were in your position, I would buy a GOOD combination square a they are very versatile. You won't find a good one at Home Depot. I would suggest Starrett (though I have a Mititoyo). There are several top end combo squares that are as accurate as a Starrett but Starrett will, at a very reasonable charge, fix it if you damage it. Expect to pay $75 to $100 for it. Seems expensive but well worth it. The cheap ones that you find at your local home center are near useless. When setting up a machine, you need accuracy. If the machine is not set up right, it will transfer this inaccuracy to the work piece. After making many pieces, all the errors will ad up to the point things won't fit. This is particularly bad for the less experienced as they may not know what the problem is, They will likely think it is something they're doing wrong when it really is a badly set up machine. You often here people say within 1/64 is close enough for woodwork. For some things it is but for many things, 1/64 off might as well be a mile. |

Seems expensive but well worth it. The cheap ones that you find at your local home center are near useless. When setting up a machine, you need accuracy. If the machine is not set up right, it will transfer this inaccuracy to the work piece. After making many pieces, all the errors will ad up to the point things won't fit. This is particularly bad for the less experienced as they may not know what the problem is, They will likely think it is something they're doing wrong when it really is a badly set up machine. You often here people say within 1/64 is close enough for woodwork. For some things it is but for many things, 1/64 off might as well be a mile. Just curious. Since most of the above applies to metal working machinery, how does it transfer to wood working tolerances? You can machine a metal piece +\- 0.001" and come back a month later and find the piece to still be within spec assuming ambient temperatures are similar. Machine a piece of wood to the same +\- 0.001" in the morning and it will be out of spec in the afternoon. Basic reason any material that gets machined, gets glued up the same day, at least in my boat yard. IMHO, expecting to maintain wood tolerances greater than +\-1/64" over any length of time is a stretch. Lew |

I move the blade so that it's flush with the handle, so it has the same shape as an engineering square. It's also handy to measure router bit height, etc. |

I'm not a big tolerance proponent, but making something like a 12" by 12" by 12" box with 1/8th" thickness required careful tolerances. That's because small errors accumulate over distance and over cobined angles. I have a few combination squares. I bought a Starrett off eBay at a good price. (I actually bought pieces separately - cheaper than buying a set.) Note that there are two kinds of heads - hardened or not. One has a pebbled finshish, and the other is smoother. The Starrett, even though it's old and has a patina, is still very readable. I have a Lufkin and Stanley rule one that has some slight rust, and the readability of the Starrett is much nicer. It's brighter and easier to read in dim light. There is not as much tarnish on it. Perhaps it's the hardened blade. Also - the little pin you use to scribe has a nice solid feel to it, compared to the other two combo squares I have. There's a certain joy in using a Starrett. One of these days I'm going to get a 4" or 6" double square Starrett. I like the Lee Valley DS ($20 on sale) very much, but one of these days.... |

Beginner's question: Say I use a fine square to mark a 3 or 4 inch line "perfectly", with an awl or knife. How can I extend that line to, say, 10 or 20 inches with accuracy that would please Starrett's customers? Does it suffice to place the knife blade into the first cut, and press the edge of the Starrett rule up against it and continue cutting with the knife against the rule? If not, what is the SOP here? A long while ago when I actually made a lot of projects, they always seemed just a little bit off where ends were supposed to meet and such. Back then I was probably using a ruler and a pencil--where, of course, the corner of a ruler could double as a square... I thought someone said that a good craftsman doesn't blame his tools...but I agree that it seems to make sense to spend a little on the one tool that all of the rest of the tools are going to be set up with... Thanks. Bill |

Thanks. Bill Bill, If you think that you will be making an investment in bigger 'n better power tools in the future, then they will require accurate setup to get the best out of them. If you are, then make the investment in a few measuring tools that will achieve the accuracy needed to verify whether your tool setup is good enough or dead-on. How accurate and to what tolerance you want to work to is your call. But to answer your question, another tool you may want is a reasonably accurate straight-edge like these http://www.leevalley.com/wood/page.a...at=1,240,45313 Bob S. |

Bob, I see myself buying a TS, BS, DP and Router. I started off several years ago interested in learning how to build an old-time banjo ("Boucher") and along the way recognized how little I knew about woodworking in general. I haven't forgotten that early goal or other ones I've acquired since then, but along the way I've been seduced by hand planes and many other implements of construction. Frankly, I enjoy learning new skills and techniques--just like lots of folks around here. This thread taught, along with related reading I did, taught me more about squares than I ever knew, and I can tell that I've just scratched the surface. I love it. If I can help furnish my house and make some music with what I learn that will be very cool--and it may even help legitimize all of the time I enjoy putting into the study of woodworking! In reply to your question, some aspects of musical instrument building require very fine tolerances (like the distances between frets) and other aspects maybe not as much. I've never really thought about what tolerance I want to work to. Giving a good answer will require knowledge I don't have yet. It's a good question though. Bill |

But I would either make additional marks along the edge, and especially the other end of the piece of wood, extending the line. and then use a straightedge or framing square. |

Easy. Use an engineering square. :-) Why Rube Goldberg it? But if I did find a reason why I needed a dial indicator to square a press table, I could certainly get some aluminum stock and create a jig for a bit less than a hundred bucks. :-) Sorry, I'm not going to be convinced that the thing is worth anywhere near what they're asking for it, nor does anything more than I can do with a dial indicator and some scraps. All I see on their horrible website [yellow text against woodgrain background, I'm dizzy) :-) ] is them trying to come up with reasons to convince me I need it. Like a TV infomercial.. "Look what it can do!" If I were a machinist, you could convince me, but not for woodwork. It sure is shiny and pretty, though. :-) -- -MIKE- "Playing is not something I do at night, it's my function in life" --Elvin Jones (1927-2004) -- http://mikedrums.com ---remove "DOT" ^^^^ to reply |
