4 x 8 mft layout
« on: July 01, 2018, 11:55 PM »
Hey!  I am looking to make a large workbench with a 4 x 8’ MDF perforated top with mft spacing. Where can I get a format that I can take to a local CNC shop to have them make it for me? Thanks!

Your custom top will need to be replaced at some point and so you will have repeating CNC costs. Check this out from Lee Valley:

For a one off cost you will have the capability to make your own custom tops time and again. It would take just over 2 hours to do a full 8x4 which is probably about the same time spent going to and from the CNC shop.

An even cheaper alternative would be to keep a master template and just use a flush trim bit to copy it. I made a stair jig about 10 years ago and afterwards flushed trimmed around 5 spare. Last week I used a new one as the old one was getting peppered with holes. Much quicker than starting from scratch!

I would recommend Peter's suggestion as well.  It's a well made system and was easy to do.  I only had one hole slightly out of whack and that was my own error - I drilled one of the 5mm guide holes through the rule which was on TOP of the other rule.  Doh!  But it's in the corner and easy to remember which is out.

Also, for what it's worth, I used Garnica plywood and got great cuts, but I did back up the plywood by placing it on a sheet of MDF.

Thanks, Peter!  Great system!
