A little while ago I was lucky enough to get a new wonderfence setup to complement all the other Incra doodaddery that's gathering dust.
Well, I blew it all off and had a play with it and the metric Master Reference Guide.
What was obvious were the lower number of joints compared to the Imperial version (51 vs 26, absent some of the good ones too). So, I wrote to them and asked a few questions. Well, they don't want to produce another metric MRG or produce any more tapes, but we discussed how they are generated and discovered... the secret sauce....
SOOOOOO... I have the beginnings of a neato spreadsheet that will create box joints, dovetails, double box/dovetails and double-double box/dovetails with metric bits and self-customised tapes.
In it, one places their desired bit diameter, bit angle, cut spacing and it will generate TWO things... first, calculate the missing parameter of either Depth Of Cut or Cut Spacing and SECOND it will generate all the tape measurements.... the blue cuts and the red cuts.
You can then mark these in mm on the back of your existing tapes, or make new ones, or follow the printout. It won't generate pictures.... yet (later, Ill write a java program to do that)
Obviously this in no way eliminates any of the books. It is to complement them. The program will assume you know what you are doing.
My thoughts are to use multiple different dovetail bits to generate truly exotic joints. These calcs can't readily be done by hand or guesswork (unless you can do tangents and divide by Pi in your noggin).
If you are interested in getting a beta to test out, say so here. :cool:
