I've been working on the "Demon" engine for a while now, and I'm close to making the rods. The print says aluminum rod with brass insert, (brass not bronze?). Aluminum and brass I have on hand.
It took me 3 tries to get the main inserts correct. So I was thinking about making them like George does, entire rod out of bronze, needs no insert, but I would have to buy the bronze.
Another option would be to make them out of aluminum, with no insert like Doc did. I have used this method on slower running engines and it has worked well, not sure about the longevity in a higher rpm engine, and yes I know Briggs engines ran like that for years. I have material on hand.
So If you guys could give your opinions, especially if you have first hand experience either good or bad, it would be appreciated. I should also comment that from past history I don't put much run time on my engines.
Thanks John
Ps. Steve if you read this, I have the plans for the blower and I was wondering if the G-code for the housing was available, I don't have a lot of experience with writing code or drawing in 3d
