Hi Gary, I notice with some keenness that you are embarking on a junk conversion of a TS16. I joined this association when the same conversion took my fancy back in 2016 (I think). I think I was the first ever to convert a TS16 from a bermuda to a junk rig. And I am happy to say I never regretted the decision! And although I went on to sell the Hartley and built my current boat, a Michalak Blobster, I remember the Hartley with fondness.
I am now about to refit my Blobster as a junk rig, which will be not so nearly as difficult because she is already rigged with an unstayed mast and a balanced lug sail.
All the best with your conversion, and if there is anything I might be able to assist you with in your decision making I am only too happy.
