Thanks Jameel,

I'm planning on going to the WIA again this year, so I'll have to look you up. Maybe you could cover up the vises for me so I'm not tempted!

I like the looks of that clamp. Have you tried it on your SW?

I have the Incra ones and they work well with my JMP.

Looks to be very similar. Curious what you see at the key difference?

I ran out and bought 3 of the Incras after seeing this. One thing I'm not wild about with them is that the bolt is 1/4-20 which has too small of a head for the slot. It works but I'd be happier if the bolt head was larger and had a better purchase beneath the table. I tried the obvious (a washer) but it made it so thick that I couldn't clear the underpinnings of the table. That would prove too cumbersome. I may try to find thinner washers or try to file some down. It'd be cooler to buy John's new ones......... I'm in.

That's pretty much what I did with my Woodpecker clamps which are very similar. I filed down the width of the washers & brazed one to each of the bolts -- works just fine.

Hello,

JKC,

It works just as well on the SW!

Everyone,

I would also like to get some more of these and outfit all my Jointmakers; let's try and talk John into doing a run of these!

Okay, I'm up for that. What's the best strategy? Flood him with emails?

I like that self-leveling feature the convex/concave curves create (the orange/champagne interface). I really am not impressed with the quadrilateral wooden blocks supplied with the JMP-v2 as hold-downs; I find them quite a kludgy feature of an otherwise spectacular piece of engineering.

That set of curves I refer to, however, still allows only a single axis of leveling orientation. If it were a ball-and-socket interface, it would be multi-axis. Is that understandable, or have I confused Dear Reader?

Build 'em, John!

AlaskaRanger,

I completely understand the ball and socket design idea, but you would only get a benefit on a beveled work piece and even then, would it hold it down, or would the wedging cause the wood to slip out under force of cutting?

You might try it with carriage bolts and file the round heads square to fit into the channels under the JMP table.
