Swapping engines

I would be surprised if Grant hasn't already fabricated one. How about it, Grant?

Have you been spying on me? Actually, on the first engine I did I was rather naughty, I just used a tap to change the threaded hole to take a standard right-hand SAE bolt, see post #9 here,

I then thought about using a smaller bolt that would pass through the threaded hole, with nuts at both ends to accomplish the same thing.
Finally I bought a left-hand die and and some bronze rod and made a couple of tools. It was not easy and not one of my great tool making moments... I thought I had documented it somewhere but can't find it.
It is also possible to use a clamp to compress the tensioner, which I tried the first time round, but the clamp tends to slip off the tangs.

I watched the video in which you mentioned you had retapped the tensioner to convert it to right-hand threads. That probably wouldn't occur to me, but as always I admired your ingenuity. I showed a couple videos in which you made some tools to a metal fabricator I know and he said, "Give that guy a metal lathe and other equipment and there's probably nothing he couldn't make."
