I'm going to answer this ignorance and them I'm done.
If you can't walk up to a machine and run it, you are the LAST person that should say anything about how **** gets done.
Second, Jon Kasse still uses a cave man block mill to do his ****. You want to call him a cave man, go ahead. Your arrogance is appalling.
You come on a thread and criticize the OP for using mild steel because of weight. How idiotic is that? Does he have a TIG welder? Most guys don't (I do and I can use it...do you and can you?). There is more than one way to save weight. Instead of criticizing the OP maybe you can help him learn other ways to reduce weight.
The most sad part of this whole deal is your assumption of the ignorance of the OP, in that you ASSume he doesn't know weight is a factor, and that it takes more HP to move more weight. That's an assault on the intelligence of the OP. You don't know his circumstances or anything else. Shame on you.
As for your "secret" oil mods I'll pass. I know in FACT how you fix it. I've done it.
Get over yourself.
