Mod’s on electric plane for backing out

[Andrew Donald]

Is it possible to regrind HSS blades on an electric plane to back out carvel planking? I thought I saw it on A2A but can’t find now

[wizbang 13]

I grind mine with an 80 grit on a disc sander.
of course, this na work for fine carpentries....only for shoveling material out de way
what reason that one cannot jus grind it convex?
other than the hard /sharp part of the blade is only in the edge.
I think a 16 grit @5000 rpmx9 inch hard backer would shovel wood out as much wood as fast and safer.

Good idea, the sander. That may work even in my hands. And you can see it as it happens, few squiggly pencil lines. Of course only Bruce would come up with that!

Festool

What plane is that for Nick. I have the baby Festool EHL 65 one handed.

Dont worry I think it’s the big one. Isn’t one one for mine - bugger

Possible the video you are thinking of is on the Tips from a Shipwright youtube.

Every professional shop I have worked in has at least one power plane modified for backing out. I have seen them done by grinding the blades convex and also seen ones where the entire sole and blade are ground. Both work great. I have also used both 4” and 8” grinders to back out and that works as well but create significantly more dust which can be a problem if working in a yard.

I ground a curve on an old set of knives for my old Makita planer, worked great to rough in any backing out of planks. Then finished up with one of my wooden planes.
I just adjusted curve to get the maximum blade showing without hitting the shoe

Dust vs. shavings.

Yes, you can profile the blades to cut a hollow.

Arbortech Power Carving head might do it.

The Lancelot (14-tooth) and Squire (22-tooth) work really well for hogging out wood, like the rolling bevel in a stem rabbet.



It's not as scary as it looks. There's a clutch built into the disk that lets go if it hits something like a nail. The chain stops and the disk keeps spinning: no kickback.

Wouldn't buy a Chinese knockoff of it though.

I've not used their Holey Galahad, but I like the idea:

I should’ve prob said, im talking maybe 1/16 or 3/32 on softwood and both those tools are way too serious. I’ve got an Arbortech and I wouldn’t dare. Not enough control for visible insides of a boat. I’m gonna try Bruce’s idea first. Note on Nicholas response he said “hogging out”. I think an 80 grit x 8” sanding disc would be a much more suitable radius.

I believe I said backing out, in my experience the modified power planes are very controllable. That said for as little as a 16th I would just use a round bottomed back out plane.

can’t see it myself. Dunno where I’d start looking for a round bottom plane and I’m too lazy to make one. It’s electricity for me

im locking thread before it degenerates any more. Thanks for all the replies some good suggestions.
