Interesting dowel jig design

Postby 9fingers » 06 Sep 2020, 16:03

I'm not a great user of dowels but I'm tempted to make one of these.

Clever use of bearings for the drill guide and easier/cheaper than buying hardened metal sleeves as guides.

a home-made version of the Wolfcraft dowelling jig. Nice if you can get the accuracy in the build

Yes, it only needs to be a little bit off and it’s not much use.

Surely the art of jig building is to be at least as accurate as the results you want to achieve from it.

I'd possibly make it from metal on the milling machine.

Are you sure you can make one without the use of a panel saw? :) *

I think dowels are unfairly looked down upon in some quarters. They are just cylindrical loose tenons, or chocolate finger shaped biscuits.


*of course I have no doubt you can

That was a very strange thing to use unless the builder does all his sawing on a panel saw as a space saver.

i've not watched any other of his videos to see what equipment he has in the shop.

That’s what I’d do if I wanted one. Having said that some of these shop made jigs are cheap enough anyway. I like making tools though so I don’t need much of an excuse to make my own. Some items I’ve made are arguably better than commercially made.

Done properly, a dowel joint is far stronger than a conventional mortice and tenon. Derek Jones when editor of F&C used a hydraulic rig to test joints to destruction; the dowel joint was the strongest of the lot. Strange but true and there are some clips on UToob of the original Dowelmax tests in Canada which Derek replicated with the same test rig - Rob

I bought a Joint Genie (I think it’s called) at a show a few years back.
Built a few bookcases using it.
Also great for drilling holes for shelf supports at the correct places.
