I use MDF, 3/4".
If you don’t have time to do it right, when will you have time to do it over?

A simple variation on that theme: a grid of 1/4" holes, some 1/4" dowel pegs from Rockler (http://www.rockler.com/product.cfm?page=2504) and some 4-degree wedges in various widths cut from 1/4" MDF. The pegs fit nice and tight in the holes because of the flutes.

The clamping method I will be using once my CNC is complete will be aluminum T-bars spaced 6" apart parallel to the X-axis. The space between T-bars will be filled with 1/2" MDF. The T-bars will be screwed and epoxied to the torsion box top surface. The 1/2" MDF will be held down with countersunk screws going into threaded inserts in the torsion box top for easy replacement.

That looks very secure Lee. :D

I have used a combination of bolting down and wedging against shelf support pins placed in 5mm holes.

However I overtightened one of the bolts and pulled the Tee-nut up through the MDF spoilboard thereby ruining it before it's time. :cry:
So I have been forced to spend the money and buy these:

I have bought enough to solve the clamping issue once and for all, I hope. I will also use a series of Tee-nuts set into the underside of my spoilboard and 5 and 6 mm holes into which I can fit the shelf pins and 6mm dowels.

My ideal solution would be vacuum however that is a long way off.....

Oh yeah....

Once I get it all sorted I will post some pictures. :D

It will take a while because the day job is taking a lot of my time at the moment.. ;)

Finally got my Spoilboard top replaced!!!! :D :D :D

As I posted earlier I overtightened a few T-nuts and pulled them part way through the old spoilboard so I was foced into replacing it.

I bite the bullet and purchased T-Tracks and installed the onto my machine with a 6" gap between them and there I have screwed down a MDF board to which I have fitted 6mm T-nuts and lots of 5mm holes. The 5mm holes are to accommodate shelf supports.

Looking at the picture above you can see the 6" MDF boards.


Looking at the picture below you can see 6mm steel nuts next to the holes where the T-nuts are and 6mm Steel Spring washers next to the holes where I have inserted screws to hold the board down.

All the other holes are the 5mm holes

Now I am going to make a number of PinchBlox like items:

And a nylon block to fit into the T-tracks. I am thinking of fitting 6 per track and then I will be able to permanently install the front track. That should ensure that I have enough blocks so that I don't have to remove the front tracks to install more in the future.

When I get them made I will post more pictures.

Looks like you'll have pretty much complete flexibility to clamp however you need to with that setup. Nice table! :)

Thanks Luke; that was the functionality that I was aiming for.

That table is almost perfect.

However I have a nagging feeling that I have missed something.........
