Make a perfect "MFT" with Qwas raildogs

[sgryd]

Absolutely not a pest. I'm flattered that you want to know more =)
After all, I hadn't been able to build this at all if it weren't for all the inspiration and ideas here at FOG. I'm glad to be able to share back to the forum.

About the boards you're wondering about.

- All interior faces are drilled with 6 x 32mm hole rows. My heavy duty sliders have 6 fastening points, hence the 6 rows.
- The middle board is a sandwiched 19+6+19 mm MDF. Target width was 45 mm to be able to mount sliders on booth sides.
- Side boards are sandwiched 19 mm MDF + 6 mm birch ply. The mdf is on the inside and flush with the 45x45 extrusion
- All boards are routed to fit the 10mm tracks in the 45x45 extrusions.
- The top of the middle board also acts as support for the sub table top (12mm birch ply)
- The middle board is not centered. This way I can store 2x SysMax in one of the wider drawers.

Great job Michael!  You've inspired me to make an assembly table with an MFT top!!

Credits..
I  mentioned that this forum was an inspiration. Thought I'd mention the two posts that really put me on the extrution-track:
Mattfc's excelent rexroth builds
Qwas 80/20 build that got me thinking of not putting an ordinary MFT on top of the bench, but to build it myself instead.

Thanks for taking the time to share your results Michael. Could someone let me know what the spacing of the 20mm holes should be? I've heard it would be 96mm is that correct?

Nice idea Michael. Now I guess I will HAVE to buy myself the hole drilling kit that I can't really afford!

Very nice LARGE MFT top.  [big grin]

I just made an MFT extension table, but to get the grid of holes, I clamped it to the existing MFT and routed each hole using a bearing bit.  It worked perfectly, but it was pretty time consuming.  I also have 2 holes that are a bit off because my bearing blew up halfway through! 

Great concept, I'm doing it your way next time!

Michael:  I see none of the pictures in your initial post, but I certainly would  like to.

I also need to see. The pics.

I would love to see these pictures. I am trying to decide on the make my own or CNC route.

Thanks

I agree pictures would be great to see.

Thanks

I was "100% CNC", then I got a quote for $400...
Now I am 100% make my own.

Considering a row of dogs on the long axis followed by a row orthogonal to that to get short ends square to a long axis.

I read this a year ago, tried it and it does work very well. The OP is a genius...

I've included a photo that might help describe the process - make a row of 20mm holes at each end of the sheet - these 2 rows at each end must be dead square and parallel to each other. Rail dogs on guide rail drop into the row at each end. Mark your 96mm spaces on the LR-32 rail and rout the grid.

Notice the outside row of holes offset from the main grid in the photo - a row like this at each end and the LR32 rail with rail dogs, plus a router and a 20mm bit is all that's required.

It's very accurate too...

Evernote to the rescue.  Been clipping interesting posts for the past several years.

This is one of those older threads where the pictures went mysteriously missing.  Thanks for posting your saved .pdf, [member=21405]jturner421[/member] !

+1 on Evernote.  I've been using it since it came out and have 100s of pics from the FOG saved up.
