This thread shows a method of reassembling the SPT clamps onto the Mark V end castings.

The SPT clamps have a right hand thread bolt in one end and a left handed bolt in the other. Screw them both all the way into the clamp handle. Back them out about 1 1/2 turn each(6 flats each). With the left hand thread on the left, slide it into the slots on the casting.

Rotate the handles(pull up on the outside) 2 to 3 turns. This pix shows the handle clamping onto SPT mounting tubes. When installed properly, the ends of the two screws will tighten against BOTH spt tubes and still NOT have either handle end press against the casting. The casting thickness is not always the same so the handle may not be centered when tight.

Install the clamp on the other end the SAME way(LH thread to the left again). If you want the clamping action to be when rotated down, reverse the handles end to end(pulling up on the outside will loosen etc.).



This thread is one of several which illustrate a method for reassembling a Mark V. Please post a reply and inform me of any errors or confusion. They WILL be fixed!
