earlsdoncobbler Posted March 27, 2008 Report Share Posted March 27, 2008 i have always had trouble i doing the black bottoms on cup plinths i see it says in the mastergrave you need to use a carbide cutter then use soft filler wax . i use a cutter maybe not the right angle then fill with wax that i brought from them but after i rub the excess off nearly all the wax comes out so i have to start again i do not do many of these any thoughts on this Quote Link to comment Share on other sites More sharing options...
Danny King Posted March 28, 2008 Report Share Posted March 28, 2008 Hi I hate these too I have a suregrave machine and I find the best results are using a spinning diamond tip, I run it thru the machine twice. Quote Link to comment Share on other sites More sharing options...

ANDY Posted March 28, 2008 Report Share Posted March 28, 2008 proper cutter job these are, i have a base cutter put aside that i can throw in with a nose cone and comes out great every time. just use an old base to get the cut right and your away.

ANDY Posted March 28, 2008 Report Share Posted March 28, 2008 forgot to add. with annuals,, I use a spring tip diamond and run it on clear tape to line up entry first. then I swap for a cutter and cone turn motor on and run the job. works great for me.

earlsdoncobbler Posted April 8, 2008 Author Report Share Posted April 8, 2008 i ordered a tungsten cutter from mastergrave which they grind for these plinths and they told me to use a fine plastic nose cone the result was top dollar the best i have ever done did it first with no practice so i will be more confident when they now come in Quote Link to comment Share on other sites More sharing options...
