Hi, I'm sure this question must have come up before but I can't seem to find an answer. Does anyone know if it is possible to purchase replacement guide bushes (the plastic bits) for Tormek jigs. I find that they tend to wear quite quickly resulting in a fair bit of play which leads to inaccuracies when grinding. It seems a ridiculous expense to have to replace the entire jig when all that needs replacing are the two twopenny ha'penny bushes. I have searched high and low to locate them with no luck at all to date. Here's hoping someone can point me in the right direction!
