Whilst working on the Z 62 twin I had a another need for my Vailley Tempest so after acquiring a Mick Reeves Torquemaster of the other model site I proceeded to modify it to suit my needs. Hear is the finished product, great for the large Temp V, Typhoon, P-40 Warhawk etc where you need to get the head into the cooling chin & swing a big prop. Its about 8.5" from the top of the plug to the center-line of the crank. The last pic shows it on the twin set up but it is in my estimation not up-to the job without a slight mod I have in mind for the future.
