long way round this , i want to have a crack at making some bronze in my furnace , to do that i needed a better crucible so i bought an A10 clay graphite one now to use it i need some lifting tongs and a pouring shank which i dont have so i will make some , but to make them i need a ring roller so i will need to make one . so i have the rough design in my head and it requires some gears so i am making those i did not want to by involute cutters so i ground a hss profile cutter and have been making the gears with the help of little douglas my shaper . and i am enjoying myself and thats all that counts few pics of some gear cutting in the shaper .
oh yeah should mention i used one of the change gears off my lathe which is module 1.5 to test fit the grind on my profile cutter. so my home made gears should be real close to m1.5 , i am making 2 40 tooth and 1 30 tooth gears . still have to make my mind up either grub screws or keyways yet , i suppose keyways would be the right way to do it .
