How do I clamp 2 boards at 135 degrees for gluing?


When it comes to doweling hard-woods I'd suggest NOT ot use the pointed brads that indent the opposing side to be drilled. While they work great for softer woods - like you think - they don't work all that well for oak.

For hard woods (when doweling) take apart a marker - get the ink-sponge that's on the inside out of it. If it's fat enough you can just put this in one of your dowel holes to mark the other side. Or drill a hole in a dowel - stick the ink sponge in there - and then put that dowel/with/sponge into the hole to mark the other side.

However: I don't rely on these things. I use careful measurements and/or templates . . .I think doing a template will make it much easier to get your drill-holes identical. To make a template: trace the end-silhouette from your rail onto cardboard or stiff paper (even plastic). on the template mark your dowel-holes and punch/cut them out . . . one template can be used to mark both ends the same.

Lots of opinions to choose from. Here's one that was dowelled in an Ipe rail.

That's amazing. There are no brackets added to specifically support that joint. There is no inner bolt, just dowel(s). And you're telling me that that doweled joint can be trusted not to break? (I'm not arguing, I just want to know.)

I know I would not succeed in trying to install a bolt and then a washer & nut through an access hole. But I've thought it through, and using a dowel (or dowels) seems feasible.

I feel guilty taking up your time when you're making kitchen cabinets, but once again I really appreciate the extremely specific information you have given.

I like the idea of a template. That I could do, on stiff transparent plastic.

I don't know if you have an opinion on these two questions:

* If I use two dowels, should they be arranged horizontally parallel, or one-above-the-other parallel?

* Why should I use wood dowels rather than brass dowels? Is it just because the glue will adhere better to the wood dowels? (The cost of the brass is not important -- I'm doing only one joint.)

It works with or without brackets.

The bolts ohmike, and havalife talked about are the best way to go. They are called "rail bolts". They screw into one side of the railing with a wood screw like end, and you drill two holes (one in the end of the rail and a bigger one in the bottom) and insert the machine bolt end in the other piece. Usually I go a little larger than the machine bolt diameter so you can adjust the pieces once you glue and bolt them together to get a perfect alignment. The hole you insert the nut into on the bottom of the machine bolt end gets a wood plug that matches the wood the rail is made from when all is done so you don't see or feel the hole,

Thanks for the "flexible hinge clamp" idea. I immediately went to my shop and cobbled one together to assemble a built-in bookcase that has a five sided shelf with a 135 degree angle. Works great

It's called a rail bolt.

If you use one of these there's no clamping needed, just some Tite Bond II.

Id use a Biscuit joiner, a jig to back up to and some bungies to pull the joint together while the glue sets.

OR use a rail bolt like Joe says LOL, LOL, LOL Darn guys a walking Hardware Store.
