I have about $45 in this. $12.50 in the steel, and $32 for the upper and lower sets from Aircraft Tool Supply.
As you can see from the pic, I did put the angle on the base to aid in getting those holes that are hard to get near trailing edges. I also added some felt to that angle to prevent scratches. There is a 1/2" bolt in each of the pillars, with the nuts attached inside the upper tubing.
I do want to thank Phil Cobbin for giving some advise for this. Mine isn't quite as robust as his, but this will do everything I need it to do. I have a 21" throat, so it should reach everything.
