How to clamp for gluing 30 degree angle

[wisardd1]

First post here, so here goes:

I am working putting together a simple quilt stand. 2x.75 stock 36" verticle with a 30 degree rake at the top (centered). It is similar to a stairway banner with a 30 degree rake. I am using a busquit cutter for the joints although I started out with tenons. Current I have the piece in a side vice on my table slanted at 30 degrees with the top on the ground pushed together and held from sliding forward by using a heavy weight in front of it. I placed some tension on it them clamped tight with the side table vice. Although it works, it feels so mickey mouse. I searched the net for clamps, looked under stairway tools, etc to no avail. I am trying to stay away from nails and screws. Any help would be appreciated. I hope this makes sense. I am using quartersawn oak and trying to stay somewhat in the arts and crafts tradition. And yes, I am brand new at this.

Welcome, Dale!

Let's see if I have this visualized right. What you're building... does it look a little like this:

...only upside-down? Except that it's upside-down now, so it'd be shaped kinda' like that right now? And you're gearing up to clamp it together like that?

If so... I'd be really tempted to clamp some scraps to the stock, then pull it together by clamping the scraps together. You can get around nearly any angle that way.

Nope more like a "T" with the top slanted 30 degrees down

The easiest thing might be to take some scrap plywood and build a jig that holds the parts in the proper orientation. Then instead of clamping the parts together at an awkward angle, you clamp each part to the jig at a normal clamping angle, letting the jig apply clamping force to the 30 degree joint.

The problem I have run into is sliding when adding clamping force. I am about reading to rounter out the design into 3/4 ply wood so I have a horizontal top to clamp to instead of trying to figure out something for the 30 degree angle. I guess I could call it the "Coffin Form Angle Clamp Jig" The piece would fit nice and snug into the form like a body into a coffin! LOL

Oh! Oh! Oh! I think I see what you're doing! You're making a PANEL, with the top board in the panel TILTED. Right?

Even for that I think I'd clamp a series of scraps to that tilted top board... possibly with one edge of the scraps beveled at 30 degrees... then apply all my panel-clamping force (pipe clamps & bar clamps) to the scraps.

Is the top edge of the topmost VERTICAL board beveled so the joint is a miter joint? That'd complicate things... a complication that could be overcome by clamping (C-clamps, g-cramps) scrap blocks both to the tilted board AND the topmost vertical one, then clamp the scrap blocks to each other. Kinda' like a hasp for a padlock on a barn door.

After the glue's set up, all the scrap blocks would come off... leaving no trace of any hotglue, since they were clamped instead of hotglued.

If your gluing that like I think you are, end grain to end grain then without a spline it's not going to be a very strong joint. Maybe you could pop a biscuit in there, if nothing else it would tend to stop it from sliding on you.

If that is similar to what he's doing, then I think I'd half lap the joints to get a whole bunch of long grain glue to long grain.

I agree with sawduster, the half lap method popped into my mind first also.

Exactly!
