Making All Wood Cam Clamps

Some men have thousands of reasons why they cannot do what they want to, when all they need is one reason why they can.

Martha Graham


I need some clamps to hold guitar sides against the guitar top while I am assembling the guitar on the work board. I really wanted to make all wooden spool clamps, but I am facing a deadline. To make wooden spools clamps I would have to buy a wood threading tap and die set, then wait 2 weeks for Lee Valley to ship me some nice maple dowels. Then I'd have to turn the spool tops and bottoms on the lathe, not that that would be a bad thing, but as I said, I'm on a deadline.





The plans that I followed to make these clamps can be found here. I thank ShopSmith for posting all those wood working tips!

The plans are quite straight forward and easy to follow, though there is a misprinted dimension, it has to do with where the hole for the pivot is located on the cam lever. Double check all the plan measurements before you begin.

There are also plans for making laminated cam clamps out there on the Internet, you just gotta do some surfing.





I didn't want to spend a lot of money, so that ruled out buying a bar of aluminum to cut into bars. I ripped some 3/8 thick strips from a nice Douglas fir 2x4x10, then ran those strips through the thickness sander so they finished to 5/16 of an inch thick. I cut all the parts, then began laminating every thing. The bars were laminated into the lower jaw so I didn't have to drill a bunch of holes to make the mortise. Then I laminated the upper jaw around the bar making sure that the jaw could slide along the bar.




Why laminate every thing? Why not, I don't have to drill and trim mortises. I spent maybe 6 six hours making these clamps.

Why Douglas fir? I had it on hand, it is one of my favorite woods. Douglas fir is strong and this stud was milled from a third or fourth growth tree, this wood is awfully light which is a plus at this point. Remember, these clamps are going to be used only to hold guitar sides in place during assembly. I don't need clamps that can produce 300+ pounds of pressure to squeeze out a bunch of glue.

Wow, how nice to have a bunch of clamps that didn't cost me $20-$30 a piece.

  1. Can you please advise the correct location for the hole on the cam lever.

    Thanks

  2. Nice job! I've thought about making such clamps for a long time. Do you pad the contact faces?

  3. Thanks, Tico!

    Yes, I will glue some cork to the contact faces to pad them today.

  4. I like these Wilson. I bet they will be a real pleasure to use.

  5. I advise that you get out your ruler and measure the plans that you have down loaded from ShopSmith before you begin making these clamps. If you can do basic addition and subtraction you can figure out the proper location of the hole for the cam lever out on your own.

  6. Wow, how timely for me, that I found your clamp making post. Thank you for taking time to notify everyone!

    O.K, timely for me because I was going to go to a Woodcraft store 20 miles away and purchase two of their cam clamps that are on sale in the next week for $8 each. This in order to copy how they are made.

    I have several steel bar clamps from the Harbor Freight Useless store. It is quite easy to break the plastic clamp as it is ratcheted tight, and I have been saving bar stock for conversion to clams. At about $2 each, new, and with a bunch of D.F. ripping waste, I will try to follow your steps!

    Thanks again, Wilson!

    1. Hey, Bruce! I am glad that I saved you a trip to Woodcraft, these clamps are fun to make. The next set I'm going to make out of walnut, because that is what I have on hand. Walnut, maple, birch, beech, cherry are all great wood to use. Once you make your clamps you may want to put a screw in the clamping arm for added strength. Don't know if I show that in the post pics. Thanks for viewing my blog!

How to Make a Traditional Froe Mallet

What holds the Holy of the Holies, what did Brahma become? Wood. Why will aspen always tremble? For the nails driven into the cross. What makes the color of wood? The soil it tastes. Cradle, fiddle, coffin, bed: wood is a column of earth made ambitious by light, and made of beauty by the rain.

Kim R. Stafford, Having Everything Right, 1986.

Rive, verb, to split
Shake, noun, a split in a piece wood. (Heart shake, ring shake)
Shake, verb, (Middle English), to split.

I know I should have been in the studio working on my back log of guitars, but the day was so nice and warm with a tall blue canopy, I couldn't stay inside. I decided that I needed to make a proper froe mallet. This style of mallet is traditional to northeastern California, primarily Tehama (where I'm from), Butte, Shasta and Plumas counties where making shingles by hand from sugar pines was an industry. I don't know if it was used in any other region along the Pacific Rim, other parts of the United States or even o…

The New Workshop: New Roof, Snow, Rain, Sub-zero Temperatures

A snowflake is one of God's most fragile creations, but look what they can do when they stick together!

Author Unknown


Cold weather and snow delayed me in getting down the corrugate tin roofing on the new workshop. January 3rd proved to be a day of snow flurries and sunshine which at least allowed me to install the roofing. Then it snowed six inches.


The temperature fell to -5 degrees Fahrenheit and it kept snowing...


...until there was 22 inches of snow on the ground. And the temperature fell some more to register -14 degrees Fahrenheit on the thermometer.



Yesterday, the temps warmed up to 36 degrees Fahrenheit with the wind gusting up to 50 mph and we lost power for about two hours.

This morning we woke up to rain and warmer weather. I am very glad that I got the new workshop "dried in" before all this snow fell.



The high reached 40 degrees today with rain and snow flurries, there is a good six inches of slush underneath all the snow. No wind to speak of today, though…

Basic Hand Tool Kit for Making a Classical Guitar, Revised

Ours is really a simple craft.

James Krenov, The Impractical Cabinetmaker, 1979


So, you want to build a guitar.

Since the original post, Basic Hand Tool Kit for Guitar Making, click here to see it, is the most popular post on this blog, I thought I would revisit it and adjust it to what I am using now to make a classical guitar.

The first thing I recommend doing is to buy or borrow copies of the following books:

Guitar Making: Tradition and Technology, by William Cumpiano and Jonathan Natelson
Making Master Guitars, by Roy Courtnall
The Guitar Maker's Workshop, by Rik Middleton

These are required reading before you begin making a guitar.

Also required reading are these books by Roy Underhill:

The Woodwright's Shop
The Woodwright's Companion
The Woodwright's Workbench
The Woodwright's Apprentice


Why these books by Mr. Underhill? You will learn valuable wood working techniques if you make any of his projects. The dovetail joints used to join a drawer together are far mor…
