Not only the original Marchioni. The next two iterations, Leitz and some Unifot/StarD, also have the long threads. When ordering the top handles (TEP-1, 2) for the camera platform, note that the Marchioni original (right) has two very long threaded bolts compared with the current KingHome Tiltall (left). This means that you will need some kind of tubular spacer placed onto the bolt to effectively shortening the threads inorder for the present handles to work with the original Marchioni. Steve Krauss (below) reports that the part "Hillman #880414" from Lowes works well. Again, this is because the current handles are not as deeply threaded as earlier. Change seems to be at the Unifoto iteration.
As example, this correspondence from Tom Conway - Hi Gary, I just now noticed that the new TEP-2 handle won’t lock the elevated position when screwed in all the way like the old one did. The short handle does lock it. I can see that this replacement TEP-2 wasn’t machined completely. The thread goes all the way to the end. On the short one, the thread is recessed back in about 1/4 “. Also I see that this replacement TEP-2 is aluminum while the original appears to be stainless steel. Can you please help me? I need the new TEP-2 part you sent me replaced. It is defective. It won’t lock the mechanism. Is there any chance I can get an original part? If not, do you have one that is properly made to replace this one? Thanks,Tom Tom- With TEP 1 and 2 and the original Marchioni, I have learned that the length of the receiving screw is part of the mix and can be solved with a spacer. - GaryGary- A ¼” piece of 3/8” copper tubing worked perfectly! The original short handle has the same thread depth, but is bored out to 5/16” diameter for the first ¼”. I would have done that if I had a floor stand drill press. My bench top drill press couldn’t accommodate the TEP 2 length. - Tom
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.
