hi, as anyone made there own bandsaw guides? i have a wadkin 20" saw. bought it off ebay and did not notice that the bottom guide was missing! new ones are a bit pricey. :x
Are you talking of the complete assembly or just the contact wheels/blocks? Have you tried talking to a local model engineering club, someone there might like the challenge.
This may be of some help.

Jimi43 has made me up a set of lignum blocks which I will be fitting and trying later this week. I also easily obtained replacement thrust bearings for my saw from eBay. Details of both the blocks and the bearings towards the end of the thread.
