« Part 4: Arm Support Part 5 of Chevalet Build series Part 6: Saw Frame »

The Pressure Roller and Clapping Jaws came together quickly. Making the pressure roller was the most work, but I came up an “easier” way to make it. I’ve seen others make this out one large piece of wood, but that seemed like a waste of wood and a lot of work. I started by cutting out the center of pressure roller, using a template from my SketchUp drawing. Then for the “ears” I found a hole saw that was about the right size. I cut the ears from a thick piece of stock, then cut them free at the band saw.

I then just glued the “ears” onto the center arm. Then it was just doing the final shaping with: rasps, skopeshaves, and a little sanding. These “ears” really only seem to be “spacers”, the real work is being handled by the steel rollers. So I really don’t think they have to made “integral” to the arm.

The “flexible” upright arm that the pressure roller rolls against, was made from Beech. I “thinned” the center section down at the table saw. The plans call of it to be glued and screwed to the seat and front seat leg. I only used screws, so it could easily be replaced or adjusted. It seem to be holding strong, with only screws.

The foot operated peddle was next. There is dovetail that connects the post to the foot rest. I cut that by hand.

The last thing was to make the clamping jaws and they are tapered slightly. They are somewhat small, so I didn’t want to the do the tapering with any power tools. I used my Jack Plane, and it made quick work of the tapering.

The jaws are only “taped” into place for now, so I can do some final adjustments on the height. On Patrick’s blogs he talks about the correct fit for the jaws. You can read more about this process here. I do my final tuning later.

I also added the diagonal support to the saw frame support. I didn’t do any fancy joinery for this. I just glued and screwed it in place.

The last thing is to work on the saw frame, which I started yesterday also. I’m hoping I can finish the saw frame up today and do the first test cuts!

wow it is really taking shape. I think you approach to the clamping jaw should work fine. The glue joint should be plenty strong. It looks like you are almost there.

Yep, that looks like a chevalet to me.
Again, very nice work.
BTW that’s the first time I’ve seen “ears” I think but then I’m not very observant.

Mike, that looks awesome. The only thing I can see from the pictures that I think you might have to tune a bit is the contact area of your jaws. It looks like you have good contact only at the very top edge. You will want to taper the face of the moving jaw at a slight angle to the back so that you get solid contact for an inch or so from the top of the jaw.

Other than that, a very solid build.

Paul – I’ve seen different “styles” of the pressure roller, this is just how Patrick has it on his plans.

Mathew – I agree the top edge of the jaws will need some “tuning”.

Nice work Mike. It won’t be long before you are cutting marquetry with it. The beech looks great too.
