i just built a routing table out of 3/4” MDF. when i mount the router underneath with a bit placed in the Collet fully in, it doesn’t really reach the cutting depth that i need.. so i started pulling the bit out about 1/4”-3/8” and doing my routing like that. any thoughts on this? should i have used 5/8” MDF? sometime is doesn’t feel safe like the bit might break or something.. though i might just be paranoid.

any recommendations would be great!

I never run my bits all the way down, I’d have to go out to the garage to look at whats in there now, but I’d think1/4 out you’d be fine with most bits. I wouldn’t pull it out more than half the length of the bit’s shaft though.

Or you could use the router to take away a little material on the underside, so you can still have the strength of the 3/4 over the rest of the table, but get the router up a little higher.

check outthe Router Forums site , they have lots of Info on instllaing routers in tables. Try useing a router plate that is only 1/4 or 3/8 inch thick. Look at this link and others on installing a router Plate.

Have fun and be safe

I think you’d be okay letting the bit out that far. I usually seat the bit fully then pull it up an 1/8” or so before tightening the collet. I would think that as long as the bit was in far enough for the entire depth of the collet to be in contact with the bit shank, you’d be okay.

In a pinch I pull the router bit up so it’s even with the inside of the collet. This way the collet still gets full grip on the bit and you get a bit extra length. I mainly do it with spirals.
