Doing a scarf joint in Wenge, seems to destroy the edges of plane blades in short order, O1, A2 and T10 steels, 30 or 45 degree microbevels. This single scarf joint took 5 sharpenings to get done.

Yes, very very hard wood. Might be better off doing that on a disc or belt sander...

My experience says it's splintery and smells funny.

I was just thicknessing some Wenge sides this afternoon (doing a laminate set this time) - 2 splinters, the sandpaper survived, I says its a success.

A lot tougher on tools than the cedar and cherry I've using for the other layers of the laminate.

You mean for a wenge neck? The peg head scarf joint? QS panels seem to plane out ok but I've never made a neck out of it and had to cut across end grain. Tell ya one thing I found, CA is an amazing filler for wenge ;)

nasty wood!
The pores go on forever.
But-treat it differently.
Not like the woods you used to working with.
It's a different animal.

I am building a wenge/sitka dred and i really like the wenge. Ready to glue the back on and have had no problems yet. Tap tone is fantastic.

Colin, I really like that set-up for holding the scarf while planing. I always struggle to get them clamped. I'm going to steal that idea! So simple but I never thought of it. . .

Cheers Bryan, very simple and holds solid. Scrap of 3/8" marine ply 3" x 4.5" or so (for strength) with 4 long screws into a 4 x 2.

Oh yeah that is a very clever idea. I've always used the Cumpiano double stick tape method but that's brilliant.

I'm sure someone's done something like that before, hardly advanced engineering.

The only instrument I’ve made that has needed significant repair after a year of use was a wenge OM (back and side cracks)

It looks good and sounds good, but I’ve stopped using it due to its many problems.

Smells horrible
Splinters
Hard on tools
Not difficult to bend, but temperamental.
Splits along the grain

There are much better options with less issues, so I’m not putting myself through it again. Life’s too short. :)

It can definitely be problematic...
