(01-03-2018, 01:52 PM)tube sizes Wrote: further to first post and other replies here are few pictures and details
the outer original tube with car and has thrust bush on end Part BM136 has OD of .561 and ID of .360
The first rotationg tube brass and part bm130 has OD .497 and id.401 ---- this is problem as will not fit into above part.
the final inner brass tube ( which fits above) Part bm129 has od .375 and id.320
Any idea's
PS when I get this sorted I will turn up a few insulators - if anyone can sketch one up will be happy to make a few extras as appears quick turning job (will be in Nylon 66 )

You can make these out of hardwood/ nylon/ ebonite or similar.
