Anyone have any good websites that explain the process of making a piston? Thanks

Are you a skilled machinist with access to a high precision lathe and mill?
perhaps he just wants to know how its made?
Check this out
Yes and no. I have access to a machine shop (my dads fabrication shop actually) but he doesn't have a mill. I have experience with mills, having set up a couple cnc mini mills at my old high school. I have done basic machine and fab work, nothing serious, but my dad is very skilled at it so i'm not to worried about it. Yeah that website is very cool. i talked to my dad and he said it would probably be easier to just machine it out of a solid aluminum rod instead of casting. I'm going to think about it more and more research, but im interested in it.
The best pistons are forged. Going from billet will give you a weaker piston. Also pistons aren't round.
yeah. but what about heat tempering a billet piston? yes no? and damn you, now i remember the whole not round part.lol arn't they smaller at the wrist pin? if i only had a 4 axis mill at my disposal.
Also they add silicon to the aluminum to make it handle the heat.
heat tempering the aluminum won't make a difference...the process of forging, and casting to a lesser extent, creates a stronger grain pattern.
i thought about making pistons too, we have some pretty high tech machines at my work but the problem is working out how "unround" pistons are.
So, start with a big block of forged 2618, and cut into that. that way you will get full material uniformity.
the skirt is the biggest part... and the crown goes in for heat expansion.... and depends on a cast sleeve... aluminum plated which is best for heat .... theres to many variables.... best to get a wiseco booklet.... measure up a piston and order one...
A lot of moped pistons are round and some of them even have the same diameter at the crown as they do the skirt. Maybe this is somewhat OK because they are so small. I have long suspected that the "kit" pistons are pure alu and the lack of silicon etc allows them to expand too much. Would'nt a ceramic piston be good?
they run ceramic pistons in F-1 cars dont they? i know that doesnt transfer as much heat to the cylinder which lets them stay a constant round even through heat ranges? not sure on that one... most kit ones i have seen where cast aluminum pistons with a plated aluminum sleeve...
you can do what bidalot does
i do believe its a regular alu moped piston with silicon/kevlar/something on the intake and exhaust sides, ill take a picture when i find my camera

really really not the same as forging it into a piston shape, sorry
maitland...one of these you mean?:

did you know that f1 engines are made to such high tolerances that they engine is essentially seized just sitting there? They literally have to pump hot coolent is through and warm oil added into it to be able to turn the damn thing on.
Just a fun fact for everybody....hehe
i dont think most moped pistons are forged anyhow. aluminum pistons dont really need to be forged, it just allows them to be lighter and stronger. you could get away with making one out of a billet of aluminum on a lathe, but it would probably be way better to buy a quality piston and build your project around that.
yeah noogie, thats it.
just watch world's fastest indian.
You know that an F1 driver letting off the gas experiences more G forces than you or do stomping the brakes at 100mph?
