This was shown in the August edition of Scootering, as manufactured by Frost Auto Restoration Techniques. They sell 5 for £13.50, which strikes me as exceptional value.
I didn’t have time to order these from Frosts, so I made my own.
You will need 25mm box section steel, 1mm sheet steel, some square section steel bar (approx 8mm) and a few old M6 threads and wing-nuts.
Cut a square of mild-steel sheet about 50mm x 50mm and drill an 7mm hole in it. This will need to be made into a square hole using a file so that the square section steel bar slips through. Now put a bend (flange) in one end so the small plate has some stability during welding (otherwise it might distort). You will cut this flange off after welding.
Now cut some of the M6 thread and cut a slot in one end so it slips on the sheet metal. Weld (or in my case, bronze weld – less heat) the thread onto the sheet metal as shown. The sheet metal can now be trimmed down and the flange removed.
Turning to the 25mm box section, drill 7mm holes in one side at 25mm intervals. Next, cut the box section into 25mm lengths (so the new 7mm hole is in the middle) and then slice the box open with a slot cut in the face opposite the 7mm hole. A 1mm cutting disc in the angle grinder is excellent for this.
Now assemble the tool. You may find that the thread needs to be trimmed to get it into the box section. The 8mm steel bar is cut into lengths of approx 20mm, and slipped into the square hole. It is not welded into place, as it has to be removable.
I trust you can now see how this works. I think it is really neat, and will be put to use in the SS90 resto later today to attach the side panel, and later the floor pan seam.
If you have time, I would contact Frosts or these items, cos I think they are excellent value.

Sticky any mods?
