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. 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! Or as much skill for that matter! Has anybody any
idea how I could get a couple made? Cheers

A few options spring to mind... You could substitute a bearing (or a
pair of them if you need the depth) - ones with 13mm OD and 4mm ID are
common. Many modern bandsaws use guide bearings - usually you set them
just set back from the teeth and a fag paper away from the blade. Mide
(Eletra Bekum) did not, but I got an after market upgrade for it to
replace the original guide blocks with bearings:

You could get a set of coolblocks[1] - they are usually 1/2" square. So
drill the centre, then pin to a board and offer up to a sander. Rotate
the blocks around the pivot against the sander until you have made them
round.

See how I made a wood guide bush ring he

plastic chopping board etc)
