Olds R20 single bore slide mod

[JoshE]

Hi all, has anybody here experimented with a single bore slide on an Olds R-20? Possibly a .508" slide. I love the my R-20 , but the slots can be squirrely and very wide. Are there any slide sections out there that might pair well?

I have an A-20 and R-20 and everything is interchangeable, and for this discussion specifically the hand slide/tenon. Is it reasonable that a good tech could take the tenon from the the A-20, pair it with another slide, and get good results?

Thanks!

The R-20 (Recording w/ F-attachment) is dual-bore 0.495" / 0.510".
What single-bore diameter would you like to use? 0.508"?

I am thinking a 0.508" slide, but if anybody's tried anything else I'd like to hear their thoughts
