Traditional clamps for soundboards and backs. Available in two sizes, spool clamps are fast, safe, and indispensable in your shop.

The smaller violin/mandolin clamp opens to 1-3/4"; the large clamp opens to 5-1/2" for guitars or cellos. Repair shops should have several dozen of each size on hand for typical gluing jobs. Cork lining on the hardwood spools helps protect the instrument.

Great clamp!

By James Stevens from Dixon, CA

StewMac has always been quick to deliver & helpful with great tools for instrument building. I now have enough of the spool clamps to build several ukes at a time. They are very well made & easy to use. I'm a retired wood shop teacher & could have built them myself but why bother with the price so cheap & the clamps made so well. One thing could improve them would be a quick release butterfly nut.

Great product.

Don't know how I managed to get away with using woodworking clamps in the past. These spool clamps give a nice even pressure. Suggest that if you're considering buying these get 3 sets so that you have plenty spare if you have an awkward piece to work on.

Spool Clamps

As with previous Stew-Mac products that I've purchased, the quality of these spool clamps is superb. A while back I made the mistake of purchasing a few cam clamps that were made overseas. They were cheaply constructed and virtually un-servicable. Keep up the good quality of your products Stew-mac. I can highly recommend your clamps.

Too time consuming

By GavinB from Perth, Australia

I always found the amount of time it took to prepare and then tighten up these clamps whilst racing against drying glue was too long and made it one of the three jobs in building a guitar that I felt I could do without....the other two being sanding and removing binding tape! i decided to give the alternative, being cam clamps a go and far prefer this option for gluing tops and bottoms to the guitar sides.

Effective and cheap

By Alberta Luthier from Alberta, Canada

Light, strong, effective and cheap, is what you want in clamps. Luthiers never have enough clamps and I just added a swack of the little ones (to replace worn old ones) for doing violin seam repair clamping; where they promptly paid for themselves. The bigger ones are great for cello and guitar seem repair clamping.

Simple, yet effectice

An amazingly simple tool, but quite effective. Could be a little bigger in diameter, but as they are, they work fine.

They arrived on time, were of an excellent quality and exactly as described.

I was going to make two dozen of these, but these were actually cheaper in the long run!

Buy Enough!

By George McIntosh from Benton Il.
(Customer's Reviews) Saturday, August 28, 2010

I have been a luthier since 1962. I recently had to remove and repair the top of a 1935 Tonk Bros. large body guitar (X-brace and bridge plate). I had not purchased spool clamps because I use rubber bands. Only the spools would work in this case. They worked very well but you need 4 sets, large size. It is always nice to have enough. G.M.
