150673 | Jack Kamishlian <kamishlian@g...> | 2005‑10‑03 | Face vise |
GGs, Thanks to a suggestion of one of you on the list, I finally made a face vise to mount in the Record vise on my workbench. I used a Lee Valley's "press screw" ($16.95). It seemed kind of light weight, but in retrospect, it does the job. I looked at their shoulder vise screw, and it was way too heavy. Now it will be easier to do dovetails, etc. without looking for a compensating piece of wood of the same thickness to keep from racking tyhe Record vise.

Since it's a semi-dedicated DT vise, I'd have though 2" capacity would be enough, and save you working over and around the screw quite so much.

I can point to one disadvantage of a shoulder vise - a skinny little girl can break it without even trying very hard. Just give it a good turn after it has bottomed out and CRACK! that cantilevered arm is history. Blake >>> "Robert Weber" |

Having only observed face and shoulder vises being used, I have a question. (The only vise I have ever used personally is my WorkMutt). I guess that I cannot see the advantages of a standard face (or worse yet, metal like a Record) vise over a shoulder vise. It would appear to have limited depth, and be terribly subject to racking without various offsetting gymnastics. By contrast, there is no racking with a shoulder vise and you can clamp anywhere behind the screw. Now, I can see where the face vise does answer some of the disadvantages of the shoulder vise - it's ungainly big on the corner of your bench, and maybe there are other problems I haven't thought about. The disadvantages of the face vise don't seem (to me) to outweigh the advantages. At times I have toyed with building Paul Pederson's multi-mode vise (http://pages.infinit.net/perrons/Paul/Woodwork/Workbench/Woodvise/woodvise. html) and I think that Jack's shoulder vise "insert" for his face vise is brilliant. Still, why bother with the shoulder vise at all? It occurs to me that you gain the advantage of clamping boards flat between dogs in the top of the vise, but isn't that handled just as well by either an end vise or a well placed holdfast?

Well, I thought about it, and figured that if I made it deeper, I could use it to hold a "small" box while I planed the sides. Also to hold drawers where the sides would have to be planed to fit. It's a little under 6" deep. But you do have a point. I could have made it shallower. And when I would need to put something wider in the vise, all I would have to do is add the right width spacer in the Record vise. That way, I could have gotten away with a shorter screw. Duh! That seems to be a better, more efficient design. Cheers, Jack in Endwell, NY BugBear asks: > > Any reason to have made it with so much capacity?

Hi Blake, The cantilevered arm is 1 1/4" thick by 4 1/2"" wide maple, and it's 4" cantilever - from the vise to the center of the screw. Don't think that it's going to break very easily. Cheers, Jack in Endwell On 10/4/05, Blake Ashley |

You can just drop the board in the vise so that it extends all the way across the width of the jaws - in fact, it can hang out both ends - then just tighten it down. Very fast for doing certain operations. Also good where you want to allow the end of the board to hang out beyond the end of the bench - like for cutting off the end of the board, or for using a spokeshave or drawknife (since I haven't yet gotten back to work on the shaving horse that I got kind of a half-start on over a year ago). A shoulder vise will hold only so much of the end of the board, with the rest of it hanging off way out there so that you need a board jack to hold the other end. Of course, for any board long enough, you'd need a board jack for a face vise as well. But yes, you're right - a shoulder vise does have some advantages over a face vise. I do really like Paul Pederson's solution - very clever - but also a very complicated project. > It occurs to me that you gain the advantage of clamping boards flat between dogs in the top of the vise, but isn't that handled > just as well by either an end vise or a well placed holdfast? Sometimes a holdfast can get in the way of what you're trying to do - like planing the face of a board - but again, yeah, that's what the end vise is for (which often is just another face vise stuck on the end of the bench). - Bill T. ------------------------------------------------------------------------ |

On my bench the maple arm is 2 1/4" by 4" and the center of the screw is about 6" out. Ain't no little girl that will break that. The 1/2" steel bolt holding the arm to the bench would fail first.

Perhaps I shouldn't have generalized and just supplied the facts as I observed them with my own eyes and ears. Once upon a time, when I had very limited shop space, I bought a Frid-style bench with a shoulder vice from a famous manufacturer. It was not cheap. One day, as I was working intently on something at the tail end of the bench, I heard a loud crack from the other end of the bench. Looking up in alarm I saw my daughter, then about 9 years old, cranking on the screw with all her minuscule might. I don't know what cracked, but something did, and it wasn't her. I stopped her immediately, but I have little doubt that had I not, she could have broken that vise. I haven't done a structural analysis to determine which particular part would break, but I'm confident something would. Maybe an engineer can tell us how much force is developed by a half-inch screw being turned by say 50 pounds at the end of a 12 inch lever? I'm sure it isn't an issue if the vise is used properly. But it just kinda soured me on the design. Blake >>> Tom Price |

I am not an engineer, but the number can't be less than 600 pounds.

You also need a support for the screw strong enough to hold it, which normally means around 2" of hardwood. Even a shoulder vise with 8" of travel thus has 2" + 8" of screw between you and a thin workpiece, which I don't like. A Record #53, OTOH, will open (quickly!) to a full 15". You can also hold a long item (e.g. 3') centrally in a face vise, where a shoulder vise only open to one side or the other. However, racking, vertical workpiece holding, and DT are better addressed by a shoulder vice. If one vice type were *without disclaimer* better than the others, there wouldn't *be* any others.

Blake Ashley wrote: > Maybe an engineer can tell us how much force > is developed by a half-inch screw being turned by say 50 pounds at the > end of a 12 inch lever? Lessee. A full turn of the lever moves the end through 2 pi R inches, i.e. 75 inches The screw moves through 1/2" per revolution. So the mechanical advantage is 75:1/2 or 150:1 A 50 Lb force thus becomes 7500 Lbs! Even 10Lb becomes 1500 Lbs BugBear (who hopes he got that right) ------------------------------------------------------------------------ |

Cool! Where'd you get the twin-screw set up? Did you fab that up yourself? Or did you take apart a Veritas twin screw? I'm asking because I have two vises that I've been thinking of turning into one big twin-screw end vise, but I need to figure out how to hook them together with chain like that. ----------------------------------------- Bill Taggart ----------------------------------------- > -----Original Message----- > From: oldtools-bounces@r... > [mailto:oldtools-bounces@r...] On Behalf Of Sean > Sent: Wednesday, October 05, 2005 11:17 AM > To: oldtools@r... > Subject: [OldTools] Face Vise > > > > Bill T posited in the Face Vise thread > Sometimes a holdfast can get in the way > of what you're trying to do - like > planing the face of a board > > > easily remedied as shown in the jpgs > at the attached URL: http://www.mm.com/user/deanj/bench/bench.html > > altho you'll note the vise as well > > > > > > > > __________________________________ > Yahoo!

Bugbear asked: >Does anyone know the pitch of large (e.g. 2") >wooden screws?< I'm tempted to reply, as Bugbear himself so often does, with just a URL: http://www.fine-tools.com/gewind.htm But no, there's no way I can restrain myself from talking; you'll be lucky to escape in an hour (see you this albatross around my neck?) The Schmid 2" screwbox (at the url) has a pitch of 2.5 t.p.i. and their 2.5" screwbox has a pitch of 2 t.p.i. By the way, I have one of their 1.25" models, and it is a superb tool and my pride and joy as a pressmaker. I wish I could afford the big ones. The Schmid sizes are right in line with historic practice. I have measured perhaps half a dozen binders' presses with screws in the 2" to 3" range and the pitch is in the range of 2 to 3 t.p.i.; probably 2.5" and 2 t.p.i. is most typical. It isn't absolutely standard: I am pretty sure that I have seen 2" screws pitched as fine as 3 and as coarse as 2, and I am pretty sure I have seen 2.5" screws as fine as 3 t.p.i. I have an old woodworkers vise screw, so badly cracked that it is unusable, and I think this is 3" and 2 t.p.i. I don't think I have ever seen a screw larger than 3" or coarser than 2 t.p.i. (I have data on this, but it is at home and I am going from memory). A lot of 1.75" screws seem to be 2 t.p.i., if I remember correctly. The Schmid screwboxes and taps are rougly ten times the price of the common Taiwanese ones where sizes are comparable (approx. $350 opposed to approx. $35 for 1-1/4"). For 1" and finer the cheap ones are perfectly OK. However, for all sizes over 1" the Taiwanese boxes are pitched too fine; and using the German ones is a joy: they are stable, clean-cutting, and easy to adjust. More than worth the extra money for them as has it. Tom Conroy Berkeley __________________________________ Yahoo!

He didn't... People have pointed out that I read 1/2" as pitch, when it was most likely OD. Further research reveals that Record sell a 1-ton (2240 Lbs); this is a small 100mm jawed engineer's vice. Lee Valley shoulder and face vise screws are OD 1 1/8" inch, pitch unspecified. Some pixel counting on http://www.leevalley.com/wood/page.aspx?c=2&p=41664&cat=1,41659 make it look like 7 TPI. Which makes for a lot of force... ratio is 75: (1/7) = 525:1 10 Lbs -> 5250 Lbs (~= 2 Tons) Does anyone know the pitch of large (e.g. 2") wooden screws?
