The pier is made up from 1-1/4" aluminum angle, 6"x36"x5/16" wall alum tubing, 3/8 SS turn buckles, 3/16 steel pop rivets, and 2 specially machined 3/4" alum plates. The crutch legs are made from 4 pieces of alum angle fastened with steel pop rivets. These seem strong enough as is, but I will have them spot welded before painting. The advantage of this design is saving the welder time of assembly and me $$$. The key to this pier is the machined plate where the upper legs are fastened. It is a triangular piece with a 6" hole bored in the center and three 6" bosses machined 120* apart. This is the classic Schaefer design and now has been used in many portable piers. The mount is being powder coated now, so I will post a shot of the completed mount later. lynn Edited by Lynnblac (04/24/09 06:15 PM) Post Extras:       jsiska professor emeritus Reged: 07/12/06 Loc: NW Ohio Re: Pier for a Schaefer Mount [Re: Lynnblac]       #3069234 - 04/26/09 08:59 PM Edit   Reply   Quote Quick Reply   Very nice.

I've been planning just such a pier but with wood legs. Do you mind a few Qs? Where did you get the 6" alum tube? What is the finished height of the pier?
