Since I built my first chevalet back in 2011 I have redesigned the blade clamps at least three times, never getting one that I really liked on all levels. My constraints were lack of metal working tools and sticking to box store metal supplies. Then last winter I asked a friend who is a hobby metalworker to make me a set of clamps more like the ones that I remembered from ASFM. With his milling machine and lathe this wasn’t too hard at all.

Fast forward to last month when I decided to try to copy them for my chevy here in Canada. I still had minimal metal working tools but went to a steel supplier and got bigger stock than the box stores carry. This gave me a better chance.

To try to make a long story a little shorter, my plan was to cut a piece of 3/4” bar at 1” and then cut away a piece to leave an “L” shape. I would then fill the “L” with a separate piece of flat bar and secure with a screw to make the blade clamp.

For the shanks I would round and thread the ends of a piece of 3/8” square bar and fit one end into a tapped hole in the “L” piece.

Here are some photos that should explain all of the above.

These work just perfectly but require a lot of hand work and took almost a whole day to make. I’m too old to work that hard so …....... faced with the task of making four sets for the four new chevalets I’m making for my marquetry school I devised a “table saw” to do some of the work for me. It’s really just a mini grinder with a cut off disc to which I have added a reference surface and a sled. It works like a hot (literally) damn.
You can see my project post of the saw here.

I cut all these pieces in about a half hour.

The rest will be about the same as the hand versions but this represents most of the hard work ….... done.

Thanks for looking in.

Love the “table saw”. Necessity the mother of invention.
Don’t worry about getting older, it is far preferable to the only alternative!

Very creative, Paul. I like those special jigs which are accurate, and help to save some time so I can move onto the actual build. Great job.

You really developed a TOOL you can really USE!
... can you get a Patent on it? Saw & Clamps?
... Might really be worth it in the long run… :)


Thank you!

I bet, Paul, that a genius like you could divine a way to build a power hack saw, with an oil dripper. A much safer instrument for cutting metal – I used one in high school metal shop. (Yeah. Four years in metal shop was completely unmarketable after graduation. Not a day in the woodshop.

So many words. I need a nap.

I copied your original aluminum clamps Paul and they have worked fine for me except that I didn’t do the greatest work on the square holes through the saw frame ends and there is just a little twist that I have to look out for while tightening the blade. Just the same, I can see the advantages of the steel clamps when it comes to holding power and durability, so I will probably copy what you have done here if I can get the steel stock needed, excepting the grinder jig as I only need one set. First though I have to make a new saw frame to atone for my sins on the original. Thanks much for letting us know about this latest improvement and how to best do it ourselves.

That’s a great idea. I’ve been tossing around making something similar for a makeshift surface grinder but I needed some ideas. This is great.

Took me a minute to figure out why you used square stock an then filed it round, but then I saw it helps keep the blade from twisting. You could use your sled and grinder to do a bit of the rounding off too.

I found I would over-tighten the aluminium ones and seize the steel screw. Here are some photos of a really good fix on the square holes in the saw frame. They will end up perfectly square and in perfect alignment. I think they are self explanatory.
The last shot shows the nice clamps my friend made me. They don’t work any better than my new ones but they sure are pretty.

Nice fix paul. Steel working is not really than woodworking.

YEP. I Dont know.
Do you have a video of one of chevalets in action. I think I am getting the idea of what you do with them. I would like to see one being used. Thankyou Kindly.

I have several chevalet videos on my YouTube channel (paulm549) but this blog entry has a couple that will give you the general idea.

Thankyou Paul.
I can see why people who do marquetry would like one of these.

I don’t know the cost, but there are online machine shops where you send them the 3d design and they send you the parts. is just an example and one that I’ve used in the past. I was pretty pleased with the outcome.
