Topic tags/keywords: clamp

Hello all,

I have been thinking about and working out a design for a hall/entry table that I would like to make for my home. The design would involve creating some curved legs using, I think, the bent lamination technique. I have never done bent lamination so this will be a first for me. I have looked into the vacume press approach but I do not want to go that route at this time. I would prefer to go the route of a bending form (positive and negative form) using clamps. There is a good deal of information out there regarding this subject so I am comfortable on how to proceed.

The problem is that I can not find a source for the kind of clamps that I will need! I have been looking for a source for the big, heavy-duty, “deep-throat”, I-bar, style of clamps that I see in many of the on-line demo’s / articals that I have studied. Typically, when I see these clamps in these articals they look to be “very-old” / vintage tools. I am starting to think that maybe these kind of clamps are not easily available today.

In any case, if anyone can give me a pointer as to where these items could be obtained, I would greatly appreciate it.

If there is one thing that I have learned in my 20+ years of building furniture:

“you can never have too many clamps”

Bessey makes some deep throat clamps. I have some that are 7” deep. I also have some long deep throat clamps that have about 5” deep throats. You might do search under boat building supplies or different clamp makers.

Think about scrap plywd jigs custom notched by you with strategic wedges driven home to serve as clamps. Especially if your alternative is buying a bunch of expensive clamps you may not use often. A solution i’ve successfully employed a time or two.

If I needed a clamp with a deep throat I would make my own wooden screw clamps. There are places where you can buy the mechanical parts and add your own wood. Alternatively, you could remove the mechanical parts from a clamp you already have. You can make this clamps with a very deep throat but the deeper the throat, the less squeezing power you will have. You can compensate for the loss of squeezing power by separating the screws further. Use a good strong wood such as hard maple, white oak or ash.

FYI – Rockler has 12” wooden screw clamps on sale for $9.99 (reg $16.99). They have a 6” throat. 6” may be enough. If not, you could either replace the wood with longer pieces or add an extension to the 12” clamp that you screw and glue to the existing clamp.

Thanks for the feedback guys. Looks like Rockler has an excellent selection of the Bessey bar clamps that will fit the bill (Bessey TG Professional Series Bar Clamps). I have not ordered anything or even looked at Rockler for many many years. I will also try to check out the full Bessey catalog to see what else they offer.

I had not really considered the jig/wedge approach but I have seen this done before. I think if I were doing more production work this would make a lot of sense (i.e. build a good solid jig or 2 and keep them around the shop for a long time/many uses).

richgreer: I think your idea about the wooden screw clamps is a good one and I’m sure I could make that work also. For some reason I have just never appreciated these style of clamps. I have had several for a long time and they just sit in a bottom drawer.

Thanks again for all of the feedback,

If you want the heavy duty Bessy clamps, try any welding supply. They have the depth and strength you are looking for.
