Testing my 3-D printed two-stroke IC engine!! 

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 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

I ended up making a metal hub instead, but I thought about embedded metal nuts into the print. 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!

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

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!!

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

@@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.
