So this hand tool thing is starting to get out of hand.

I was making some full blind dovetails last week and thought I was doing just fine. I was actually but Patrick Edwards, hand tool guru, said I could do better if I had a miter jack. OK, a miter jack it is. So about two days and $25 worth of box store Oak (and a press clamp borrowed from my veneer press) later here it is.

This is something I have never even dreamed of, truly a creature of the galoot halls where guys like me feel like cowboys at the opera. That’s OK though, I’m here to learn. It turns out that this somewhat simple jig easily creates amazingly perfect miters. ...... who knew? ................and that’s not all. On the back side it serves the same function for 90 degrees. ..... and serves as a clamp for cutting / chopping the dovetail parts of the joint I was making before aiding in the production of the little miter on the corner.

I think I’m going to like this new friend. I’d like you to meet ….... Jack.

EDIT: I should mention I used a plan I found online, from Shop Notes.l

Ok, that looks perfect. So when are you going to start selling off your power tools?

Iv’e seen a few in the antique stores, kinda pricey and needed TLC. Use plans of any sort or just winged it? I’m liking what I see and looking forward to a report on its use!

Like a Fancy Shooting board?

Would it be possible to make some Inserts, etc. that would fit into your existing vice?

That’s COOL… never saw one like that before.

Thank you.

Wow. You have really turned.
Did you use hide glue too? And I think it is missing your trademark logo on the end :)

I am missing something about these shooting board things. Doesn’t it get chewed up every time you use it? The plane will gouge (or at least plane) some of the wooden structure away.

Neat though. I could see liking that.

Paul, when I get over “cowboys at the opera,” I may build one of these. Nice post.

I don’t know Jack either, but I can smell a galoot a mile away. And this sure smells galoot-ish. But it is so cute it just makes me want to build one too. Too cool Paul. I do agree, it is lacking a circle logo.

I can see where the Donkey’s Ear keeps the plane from changing the jig, however, Jack looks vulnerable to the plane.

very nice miter jack, it falls in line with the shooting boards and donkeys ear. They were once called “screw miter shooting clamp.”

John, no power tool clear out sale anytime soon I’m afraid, sorry.

Kevin, plans from Shop Notes. I added a link to the post.

Joe, you can add a cleat on the bottom to suit whatever vice you want to use. Mine seems to work well in the wagon vice.

Steve, of course it’s hide glue and yes the jig does get chewed occasionally. I asked Patrick the same question and he said that you just need to re-surface now and then. I can live with that.

Philip, check out the plan link. The dog’s ear is a little different and it’s included in the link.

Rance and Steve, OK tomorrow I’ll add my cypher.

Thanks all for the comments.
