My work hold in progress for S3

Post by designxtek » Wed Sep 30, 2015 6:00 am

Started drilling holes in my MDF wasteboard.

Added T Nuts.

I accidentally hammered one of the T Nuts too hard and it made my MDF warp a little around the area. :(
Hopefully it won't affect my work holding too much once I get the mounts done.

I will definitely get the aluminum threaded surface when Carbide3D comes out with it. I think the MDF will eventually warp over time.

If it warps you used too thin MDF...

I used the same type of nuts and 15mm plywood for my first wasteboard.
Now I'm using the type you screw in, and 22mm Plywood.
(I have 361 nuts, in a 19x19 grid... My fingertips hurts!)

There's a problem with those nuts that someone should have mentioned earlier...
Unless they sit very tightly, it's possible to accidentally push them back out if you insert the bolt a bit too roughly.

Done for now. I'm almost out of T-Nuts.

I did a similar thing with t-screws, and found that holding the object in place with hot glue worked extremely well. Have milled wood and aluminium....no issues with movement.

Hot glue? As in you hot glue a workpiece?.... Or you put in tee nuts then hot glued tee nut on the back to keep it inserted?

The CAM locks work much the same as the eccentric nuts — look at the shapes and hole placement, then envision how things would move when the mechanism was worked.

I believe we have links for them on the wiki: http://www.shapeoko.com/wiki/index.php/ ... mp_Designs

Hi there, I hot glue the working material to the waste board without anything else (e.g no clamps)
