Brace reamer bit?

[Fuzzie]

Not sure what I'll use it for but it followed me home anyway.

I was literally using mine today for some round tenons. If you get an appropriately sized tenon cutter then these staked joints are really something... I takes multiple whacks with the mallet to unseat them. Bordering on a glueless joint if cut right.

I think you'll find a project for it eventually

Two have followed me home. I believe these are too shallow (too short a taper) for tenons, and are for plumbers etc to relieve the ends of pipes.

Of course I may have been misled...

Not sure I follow you Luke. Maybe a picture would help.

I can perhaps imagine it could be used to flare out one side of a hole that receives a round tenon so it can then be wedged in solidly, but as Vann says it would be a fairly extreme flare.

I was cutting joints like these:

Only they were through tenons so that I could plane them flat on the other side.

This is the first one I found...

The second one is smaller and came with a bunch of other brace bits.

I'm sure I've seen them in an old cattledog since - but can't think where, ATM.

Cheers, Vann.

Yes Vann, here it is a Repaimans Deburring Reamer.

Luke, Notwithstanding the drawing - which looks like the tip of a cricket stump to me, the rest of that article seems to show a very similar bit but with a shallower taper. The real trick would be to find a matching tenon cutter. http://www.wonkeedonkeetools.co.uk/s...ered-spoon-bit

Also my understanding of a spoon bit is one of these http://www.highlandwoodworking.com/m...spoonbits.aspx

Yeah, I knew I wanted to make these style joints eventually, so I picked up a Veritas pair. I believe the reamer and tenon cutter, which is basically a glorified pencil sharpener, were around $70 all up. Throw in the $15 brace and it's not a bargain buy, but it's all you need for tapered, round tenon joints.

You may be able to make your own appropriately sized tenon cutter by using some wood, a plane blade, and the reamer itself? Sounds reasonably doable I think. Just gotta be super precise when reaming out the hole which will later define the tenon profile.
