I am a newbie working on a picnic table, making this one: http://members.shaw.ca/bomr/ptabl.htm
I have all the wood cut and I am ready to drill for assembly. But, I want to make sure that the holes are drilled perfectly so the angles and dimensions are right on - I don't want this sucker to rock!
My challenge is to get the 2 legs aligned at a perfect 90 degree angle and while they stay aligned unclamped, sandwich them between the 2 top beams so that the top beams are centered perfectly and at a 45 degree angle to the legs.
I can certainly come close. But 'wiggling' as the article suggests isn't getting it perfect for me. Maybe I don't have the right clamps but I haven't been able to clamp the legs together (odd angle) in a way that allows me to get the top beams on good enough.
I have a speed square to help get the angles right. The problem is more of clamping and holding it still while I 'wiggle.'
Suggestions on the best way to clamp the legs together while I get them situated on the beams?
I was thinking of starting with one leg, and using a small screw that goes only half way through the bottom top beam so as not to mar it. Then I can put the other leg onto the top beam, aligning it at the right angle, assuming the first leg is on the top beam properly. Then I can put on the top top beam, and drill everything and remove the 'clamp' screws.
Sorry for the confusion. I know this makes no sense unless you are familiar with this design. Just figured I'd give it a shot. Any and all help is most appreciated!!
