I have read the threads on this but I am wondering if it should be done with a high or low rpm and or high or low feed speed. Also what about a lubricant?
thanks!
thanks!
Even with a plexi bit it is very easy to crack the plexi. Definitely practise on scrap pieces before you try to do it for real.
I also found that having a piece of wood under the hole you're drill is essential. You want to do your best to not let the material grab the bit, this will definitely cause a crack.
... do you use a solid piece of wood to back it up or is there a hole in it?
