Another workholding setup

We're all influenced by our backgrounds. Here's the kind of workholding clamp a lumberjack might devise.


Top view, a sign blank is clamped in place.


Another top view with sign blank clamped in place.


Top view, nothing clamped. Note the dogs placed in the holes.


Underside view, showing the all-thread slot. I'll come up with a better handle knob eventually.

I laminated a bunch of hemlock boards into one 102" x 16" x 1.25" plank.
I then set my tablesaw at 15° and ripped the plank into three pieces by taking 2 1/2" off each long side. The center piece was then shortened 6 1/2". The remaining 95.5" long chunk was cut 30" from one end.

The two edges and the longest center piece were then reassembled and glued. The plank now has a dovetail section in which the 30" long piece can freely slide.

Now surface the whole thing on your MechMate, both sides, cut an array of 1 1/2" square holes, 6" on center in both the plank and the dovetailed sliding piece.

Rout a groove and some crosswise notches in the underside of the sliding piece to accept a chunk of all-thread (I used 1/2") and nuts. Drill a matching hole through your end-piece and attach a handle to the all-thread.

Cut at least four blocks, 1 3/4" x 1 7/16" x 1 7/16". Finish the assembly if desired. I used linseed oil.

In use, it's necessary to clamp the assembly to the tabletop.

Nice going Jeff…. I was just considering using a wood tall vise approach too !
It must be a woodworker thing
Thanks for sharing !
BTW, how are you enjoying your wood table set up ?
Is it to YOUR satisfaction & tolerance ( finished work by the router that is !)?
Amicalement, Robert

Thanks Robert,
The table has been great, it is really quite stable and solid. Once you surface the spoilboard, everything is flat to the cutting tool.

There are lots of challenges to work through, but the table really isn't one of them.

I love the upper photo, I respect "git 'r done" guys.

But I'm unsure what the guy standing on forklift "A" holding on to forklift "B" thinks he's doing.

(I'm sure the operator in the bomb photo is absent because he's in the locker room changing pants)

The guy on forklift A is the "active counter weight system" When the load on forklift B is removed he is supposed to jump off

The Driver of the second forklift is not in the locker room.. He was last seen jumping over the far fence, in a single bound and has not been seen since

Table Hold-Down

Jeff:

Thanks for the hold down concept and photos. I am starting to build one for myself. Great idea and execution.
