Hi everyone, I've inherited an ELU TGS172 from my grandpa who passed recently. The saw seems to be in pretty good condition. However its missing both the mitre fence and riving knife, though it looks like the assembly for the riving knife is all there.

Does anyone have a template of the riving knife for this saw and thickness of sheet required to fabricate this myself? I believe the TGS172 and TGS173 have the same riving knife?

I did try to purchase one online here in Australia but after the order went through I got an email from the vendor saying the knife is no longer manufactured and was issued a refund. If anyone knows where I could purchase one that would be great too.
