I could fess up to using the scraper, but I wont as the judge would sentence me with non parole, for using hand tools.
Look guys, even I'll admit that non-MDF looks better and sniffs better when barbq'd on the laser... however it's costly... not subsidised by NASA,Pottzy!
RC, I picked the sheets of walnut up at the timber show in Melbourne many years ago... this is what I have left after cutting 3 puzzles out of two small 7mm thick sheets (wastefully dressed down to 5.85mm) and I was so disgusted in myself that I was prepared to blaspheme and quote measurements of around 24" x 5 1/2", that was "reduced" to the on sale price of $55.
The design was great, the laser was accurate, however, one doesn't take into account the idiot that leans on the "Z" axis button of the laser to have a peek at the progress, and wonder why the cut was out of focus.
If your first cut is too short... Take the second cut from the longer end... LBD
