they see themselves as problem solvers
I have one you'll find amusing. In (what was) the Iron Curtain countries Harley-Davidson WW2 leftovers are very valuable but extremely expensive to rebuild. "We need those small needle bearings for the transmission shafts, but $$$ and hard to find". What to do? They used short sections of wire coat hangars, cut to length, packed in heavy grease.

Quite a few years ago, when I had plenty of time and no $$$, I cobbled quite a few piles of old junk together. They always ran surprisingly well and nothing ever failed.
Even on old junk, cleanliness and attention to details matter........ and it helps if you kinda know what you’re doing(which is about how it was back then....... I “kinda” knew what I was doing).

I had the same problems with galling trying to use the Speed Pro Hi Po rocker shafts with ductile iron rockers Ended up only using either Iskys or RAS shafts, that cures those problems I had to learn the same lesson on CAT aluminum roller rocker arm also, don't use the Speed Pro Hi Po shafts on them either

When the rocker grabs the shaft it's usually a volume/pressure issue. I don't like idle oil pressure less that about 45 pounds hot. It's also why I always use a HV pump. You get more oil there, sooner.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
