Pretty darn good for 3 hours of work, or did you reset that red clock every time you took a picture? :lol: I'm impressed with your work. Got a bit of an idea. Pour molding plaster around that piece of wax. Burn out the wax and make an investment casting that can be used as a mold for making many. Never know who else might want one. Bernd |

I too am a bit of a duffer when it comes to trig :scratch: :scratch:. Trouble was that my mother tried to drum the elements into me before we did it at school, and she used different 1920's notation - base, perpendicular and hypotenuse. Some Boys Have Curly Brown Hair Till Painted Black had something to do with it, but only served to confuse me when we were taught something different at school. Now, I do it the easy way, using the triangle calculators on here (some of the others can also come in useful): http://www.cleavebooks.co.uk/scol/index.htm Andy |

Thanks chaps, for your kind words, they are much appreciated... CrewCab - I wouldn't have dared go straight for the Ali, although as you say, these first operations have gone OK so far. Of course, it helps that I can abuse the wax mercilessly - most of the cuts I've taken have been full depth & full width right from the get go; obviously, I won't be able to push the aluminium that hard. On the other hand, the aluminium shouldn't bulge under clamping pressure, which ought to make dialling in a damn sight easier... Bernd - Not such a bad idea... but I think, with all the hassles of casting (making the mould bigger to account for shrinkage, actually doing the casting, and so on) I think I'll stick to making them out of billet. For whatever reason, add the word "billet" to anyting in the UK & suddenly it gets a whole lot more expensive.... I'm definitely considering making these for sale, provided I can get the machining time down to reasonable levels (which will almost certainly involve making jigs - :proj:) in the near future. Maths & trig - if you want, I'm happy to do a detailed write-up on the maths of setting your angles; but it's all high school stuff, I ran out of maths ability about 1/2 way through my A-levels (integration.... uck). Let me know if you do... |
