Hi Steve,you have caught my attention with your 2mm MDF discs,would you care to elaborate on thih method or do I have to buy a DVD???.
Peter.
No you don't have to, I'd just be grateful if you did, it's how I get to eat.
I use it for 1/16" blades. Wider blades might need thicker MDF, of course, but the principle is the same.
Guides conventionally support the body of the blade, but clear the teeth. That way the teeth do not damage, nor get damaged by, the guides. But with very narrow blades there is virtually no body to support. My 1/16" blades are like coping saw blades, there is nothing there.
I cut a disk of MDF and stick it in place on each blade guide bearing. Instead of clearing the teeth, the guides can now be positioned over the whole blade. And Instead of using a piece of paper to give me clearance, I set the guides to touch the blade. As soon as the machine starts, the teeth cut into the MDF, creating all the clearance it needs and no more. Just like ZCI on a TS
Of course, if I use it for twisty-turny work the MDF disks get chewed up more quickly than if I stick to straight cuts, but they are easy to replace and cost nothing to make.

Shall we form a club?
I've no objection to people spending their money on kit to do a specific job, I enjoy doing so myself when I feel the need, but I can't help feeling that this is a solution looking for a problem, that's all. And of course, I like it when they spend their money with me rather than with somebody else
BTW, I remembered that my mate Brian has a little Inca, small but nicely engineered and that came with a rear thrust bearing that looks very similar indeed to the gadget in question, so they are obviously not the only ones to think it is a good idea. But again, the Inca has guide blocks rather than guide bearings, so are dead easy to replace with Cool Blocks or Tufnol or some such, again giving zero clearance support.
