January 30, 20206 yr Hey Made these tall jackstands the other day for working on cars. They are not quite done yet but the bases are complete. I made a couple jigs so they all turned out the same and I'm pretty happy with how they turned out. They are made out of sch 80 seamless pipe some 1"×1/4" flatbar and 3/16" plate. Finished they will be adjustable from 15" to 22". Let me know what you think. Edited January 31, 20206 yr by Mod30 Resize large photo.
January 30, 20206 yr Excellent...probably worth sandblasting and powder coating because they'll be around for your great-great grandkids to use. What hole diameter and pin were you planning on for the riser? Since that's the weak point on these (being built like a tank), I was curious what your plan was for those cross pins.
January 31, 20206 yr Powder coat can get chipped or dinged and can not be repaired easily. Water gets undeer the power coat and starts to rust, progressively popping off more and more of the power coat. Suggest you sandblast, prime and paint. Any chip or ding can be covered with paint and your protected again.

The sliding top section will have to be just bare metal and polished up otherwise i think they will bind because the 1 1/2" pipe in the 2 " is a pretty tight fit. The pins will be 1/2" grade 8 bolts. I might try to mill a ball detent with a set screw into the bolt pins but I'll see how that works out. The sheer strength of a 1/2" gr 8 bolt on a tight fit like that should be quite a bit, actually probably stronger than the legs. Anyways. thanks guys.

February 8, 20206 yr Author Jackstands now finished before paint. Probably try them out today on the truck to put a grease nipple in the slip yolk on my rear driveshaft.
