I don't wax on, wax off I use WD40 PTFE or SILICONE spray and the PTFE is great for double glassed window hinges in fact any hinge no sticky residue for dust and grime to stick to

Wow and straight lines good work the only time I would use a spiral if it's to big to turn in the saw and I have no choice, I won't be doing fonts again with them in a hurry. Roly
Well I've always hated spiral blades but I needed a No1 or 2 ultra reverse but didn't have any but I did have a spiral and can't cut a straight line for toffee and I can't go over the top of letters without chopping the tops off is it the blade or user incompetence.I think it's the latter. So I bought some more Flying dutchman UR blades and I'll wait rather than ruin the job. So see the worst cut I've ever made he didn't shepherd me on this one. Is there anyone else feels this way.

This is my third saw and by far the best. I went from two bone shaking saws with keys to change blades to the EX21 a Moskvitch to a Ferrari and touch wood should anything go wrong I'd buy another. Love it. I tuck it up to bed each night Roly
