Air-cooled engines from this era are really something special, aren’t they? The people who created designs that are still loved after all these years are truly great.




It really makes things look brand new (´・ω・´)Shiny!

I was puzzled about how to remove it.
• If it’s just once, punch it out roughly
• If you want to consider future use, make something simple
I was going “hmm, hmm, hmm?” and decided on the latter…
The next problem becomes “how do I make it in a snap?”
For me, “cutting” and “welding” are the easiest.
I didn’t want to use a lathe or milling machine, so I made it by process of elimination.
The window slot dimensions are about 4.2 × 23 mm.
I cut SUS304 t=2 mm, 22.5 × 15 mm in two pieces with a shear, and welded them to a scrap SUS pipe.
When making tools like this, I think “if it doesn’t look decent, you’ll lose it, right?”



If internal pressure builds up and it pops out, that would be scary.


I hope that with each job it gets cleaner and runs better.
