Or get quite a few made and flog the surplus on ebay?

The blade guide rollers on my c.40 year old Burgess bandsaw are badly worn
and because of it's age replacement guide rollers appear unavailable. They
appear to be made of nylon, 13mm o/d, 5mm i/d, 10mm long.

Measured with what OOI?

I'm sure Steve on "The Repair Shop" would just turn up a suitable bit of
nylon in the wink of an eye, but I haven't got a lathe like he has!

Few have these days.

Or as much skill for that matter!

It's mostly practice.

Has anybody any idea how I could get a couple made?

Any job like that is likely to cost more than the saw cost to replace
(these days) so it's down to finding someone with one and some nylon
stock that wants to do it for the S&G's.

I wonder how well some 3D printed ones would work? I'm only setup for
PLA and they would be very easy to design / print [1] but it depends
how much friction was on them and how hot they got as to how long they
might last?

If we are confident in the dimensions I'm happy to print you some (4?)
and stick em in the post?

Failing that, when I get round to the end of my own list and near my
lathe ...

Cheers, T i m
