WH6, what radius roundover bit for 1/4" ply

#1 Post by Seth »

What size roundover bit is appropriate to use with 1/4" BB ply? Want the edges to be as "soft" as possible. Is a 1/4" radius bit too much?

Just the outside edges and port/hand hole. Don't want to bullnose the mouth.

Thanks guys :thumbsup:

Hey Seth,
Rather than a round over, I'd be inclined to Aris the wood (ie knock the edge off with a plane) then sand to suit.
Far to easy with 1/4" ply to take to much with a round over, and it's hard to put back again...

DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" KL3010LF , 2 x 28" 3012LF.
WH8: x 6 with melded array wired series/parallel.
Bunter's Audio and Lighting "like"s would be most appreciated...

Even using a 3/8" radius only reduces the minimum cross section at the joint by 1/16". A 1/4" radius doesn't reduce it at all.
