making a base plate help please ?
OK i'm not generaly thick but I am trying to get my head round one thing, making the hole and lip for the pc type bush's. I am using acrylic, I have 5mm thick and 2mm thick and the way I was going to do it was make the base is this, I have used the Erbauer standard base and coppied that, cutting it out using my rotozip and the circular cutting tool, the way I thought you found the center point was to mount the new base plate on the router and then by using say a V bit gently plunge the router to just pierce the acrylic, I thought that by doing that would make the hole central ? am I right ?
then using the center hole I have just made (only small hole by the way say 3mm?)
then using a forstner bit to sink a rebate to fit the bushing adapter plate. finally i could use any number of bigger router bits to cut the through hole with the new base plate fitted?
does this make any sense ? because other than this way I cant think of a way of making sure the base plate hole and fitting for the adapter plate would be central
