Tbh if your a quality welder it 100% should transfer i should be able to give you a schematic and you should be able to 100% build it as a quality welder. Thats literally there job. The too hot is just silly... it either is a good weld or isnt. Ask an iron worker.
that analogy is just dumb. Did I start in cars? Sure. Flat rate sucks went to RVs and trailers. Then moved down south and went to tractors and forklifts. Thats like saying because I only have car experience in dont know how to fill a tractor tire with washer fluid.
Anyway
Same thing with a quality mechanic. If it has moving parts he should be able to figure it out and fix it. If not hes a parts changer. We do t have the choice i. The field sometimes. I get the point of feel and eye. But if you dont have that natrually you prob should put the wrench down. Add repair manuels ontop of that and yeah if a trade mechanic cant do it.. A bike doesnt even have as many parts as a single wet brake system or have enough hydraulic pressure to cut you to the bone. Theres nothing on a bicycle mechanically that scares me to fix. Even if it takes me a try or 3. Its a $50 junk yard bicycle not $150k forklift or $400k combine. Im not scared of breaking a part that I can find in the garbage pile on bulk garbage day. Again not being mean its just the truth even your crazy $6000 carbon bikes. I deal with batteries that cost more lmao if im on here asking a question its because I haven't touched it yet. Ntm the tools...

the eliteism here is absolutely wild. I always knew cyclists were snobs (not all of you) but damn this forum set it in stone. God forbid im confident in myself and my work to work on a 30 year old bicycle. Fk what i know about equipment and systems a bike tech would scream in horror just looking at.
