I‘m interested in knowing the manufacturing process of the motrcycle parts mentioned:piston,engine block, brake shoe. Also, a full equipment requirement for manufacturing these products and the dealers involved as well as the invoices for these equipment. It‘s not impossible but tasking
Most of the parts are cast aluminum or iron. Google the rest under casting machines equipment as it is too tasking to put everything here.
Pistons are usually made from medium carbon steel and turned on a lathe, engine blocks are made from steel and are made either by hand (expensive) or on a CNC mill,
they are usually castings, then machined to start off you'd need a furnace or something to heat a crucible up to high enough temperatures for the metal you are using to liquify you will need wooden mould's to make castings in casting sand once you've got the castings done you will need a milling machine and a metal work lathe to machine the parts from the castings, this isnt just something that can be done in a day, you need experience with furnaces and casting before starting as it can be very dangerous, to go out and buy the machinery required you'd be looking anything around ?13,000 for a milling machine the right size, and around ?2000 for a lathe the right size, if you just go straight onto using these machinery without any training you will definatly loose a finger or two, there not toys and a milling machine and lathe from somewhere like machine mart isnt any good for what your after as they are too light work and cannot cope with the bigger blocks to fabricate plus ontop of all of this you need the tools for the miller and lath and they can be anything up to ?200 each If your looking to do this as a one off then i wouldn't waste my time and money, but for a business id advise find somewhere what does engine rebuilds and try and get a job for a few years there then try and get a job manufacturing engines then build your machinery up gradually,
