outwards in .... if it spelches then it should be on the inside and not seen. Sharp tool, fast as possible and do not force it ... let the tool do the cutting. Don't let it get too hot as you will "burn" the resin and leave the cut line discoloured. Best thing to do is work out which piece you will cut out / off and then practice on the bit that will become scrap before going for the proper cut. All that said, don't be put off ... it is easy to do. |
