Did you go back and read that post from last year that jma referred to a couple of posts ago?SONinjaGuy wrote:Anyone have tips for making a square-base tower jig. Last year, I wasn't the senior tower builder so it didn't matter if I was good or not, but now I am and I don't want to be making towers without a jig anymore, as they are never very successful.
It's described in the context of a 3-leg tower, but applicable to a 4-legger. There are lots of ways to approach.
The.....very, very basics, in terms of "tips"?
Read back through this year's posts and last year's. That will bring your level of understanding WAY up.
You're locating 4 legs in 3-D space.
You need to dimensionally define where you need the ends of the legs to be-for lower/base portion, and for upper chimney portion.
You need those dimensions, pretty darn precisely, from the theoretical, vertical centerline of the tower
You need to build something solid that holds the legs in your "design configuration". That probably means 2 jigs- une for the upper/one for the lower
It needs to be strong enough to hold the legs so they can't move while you attach your bracing between the legs.
You need to be able to lift the tower (or section) off the jig when you've added the bracing (i.e., not glue the tower to the jig while you're glueing bracing to the legs)
The more precisely you can build the jig, so the legs are positioned symmetrically around the centerline, the better you will do.
