You could try captive nuts in the hub to increase clamping pressure. Or maybe look for a metal mounting hub for that shaft diameter and you could bolt the flywheel to that.
I actually made a full metal one, it is way over built, I just used some scrap which was some 1/4 inch flat bar, but it works really good. My next issue is that my mounts are to weak, I think I need to lower the compression ratio. Thank you for watching!
I tried that before, but the crank shaft is extremely hard, so I will need to use a blow torch and soften it before I can do that, but I can give it a try!
I did that, but I like how you’re thinking! I think that if I make a metal hub it might work, because when I use the 3d printed one it just strips the threads, so if I use a metal nut sandwiched in 2 pieces of the 1/8 inch steel flat bar I think I should get enough torque on it to work. Thank you for watching!!
@@strangeman4200 I am using hatchbox ABS filament, because it is strong and heat resistant, the crank case is PETG, and the cylinder housing and the head is the ABS.
Super interesting that you printed all of this #smart

Keep it up!
might need to play with ways of making a keyway system work
I ended up making a new hub from metal, but my uncle actually suggested that!
Thank you for watching!
@@aroundtheyardfun looking forward to see how it does

Screwdrive proved to be a good purchase…LOL
try use a thinner bolt and drill a hole right through the crankshaft

Oh. Okay. One solution is to file it down with like an angle grinder so it has a flat side@@aroundtheyardfun

No problem. That sound like a good idea. By the way which plastic are you using?@@aroundtheyardfun

how about embedding metal nuts in the printed part?
I ended up making a metal hub instead, but I thought about embedded metal nuts into the print.
