Tom - So if I follow the 5/16" depth reasoning, that extra bore size IS a sort of spacer when the original TEP1 reached the bottom and begin to tighten. I wonder what the thinking was vs today's Tiltall? May I add this info to that blog post? - Gary Gary- I think I’d call it a sleeve that has to slide between outer cylinder and the threaded shaft. Feel free to put the info on your blog. If I get a chance, I’ll make a drawing showing how I think the mechanism works. -Tom
Another update from Steve Krauss (Feb 2014) - I finally had time to run by Lowes and get some steel sleeves - 1/4" x 3/8 x 1/2" - they work PERFECTLY, just as you indicated. These steel sleeves I got are dimensionally identical to the handle - same outside diameter, slide perfectly over the threads, perfect function. It's a "Hillman #880414". Thank you so much for your fine parts and help. Now I have two fully-functioning classic Tiltalls! With my carbon fiber Gitzo I'm well equipped.
