Last August 29th I wrote about How I’ve made some work stands.
Work supports seem to share a category with clamps - there are never too many. This is just another method of making a T-handle lock especially good for anyone who has access to pipe and pipe fittings and needs another adjustable work support.
The pipe tee fitting is the key feature to this design. It is the locking mechanism which hold the height adjustment and lets the pot pivot. After I made the drawing I decided it might have been better to use the larger pipe for the segment which threads into the base coupler and let the smaller pipe run up to the bracket. This would keep the center of mass lower.
