My BT48 Vac Table Project

[Brady Watson]

The shame of it is, that little Festool probably sucks harder than the pump.

Quick question about the plenum......
Does it matter how dense the grid pattern is? In another words, does a less dense or more dense pattern make a difference with the sucking power?

Larger air volume is better than lower.

So how is the vac project going??

Very nice Idea, looks good

More to follow soon.......plenum done (something out of the ordinary) and now 3D printing some custom clips and brackets to hold the ally square tubing underneath the table.
Been busy finishing off my sim demo centre and getting civil aviation certifications that has had me tied up in red tape......so have not had a chance to do anything on the bot for a few weeks.

FYI - 1" squares with .25 to .5" channels are fine. You can go .125 to .25" deep and get all the airflow you'll need. Use a downcut bit to keep from knocking the squares off.

Oops too late Brady....already cut the plenum.....0.375" deep, 0.75" x 1" gap........
Ah well see how it goes......worse that happens is I do it again.......
Thanks for the advice anyway!
Cheers

All that fancy cutting won't give you any better performance than just a downcut with channels...It's been tried 6 ways from Sunday, including ball vs V-bit vs square etc. As long as you have channels to evacuate the air from the plenum, you're good. What you have will be fine - unless you throw a really high Hg" vac at it - you may get some dimples in the surface.

Yea I know......must have been my arty side that made me diverge to a fancy cut. Next time I'll be more practical!!!
