I like it but fear the engine will drop out when my weld fails here (green arrow).
I know 1/4 plate is probably fine, but this is gunna be ME hot gluing it. I guess the 3” backbone will help prevent it from folding if the down tube and “rafter-like” supports in the rear are good.

What are frames called that don’t have a down tube? Like if the engine was suspended from the backbone?

Build a cube / box “engine frame” that hangs from the backbone… then put engine plate on bottom of engine cube?IMG_7036.jpegimage.jpg

You take worry to a whole new level!
Even crappy welds would be plenty strong.
You are easier to please than Reddit…

Reddit was tough on the welds that connect the head to the frame…

“that would not hold”
“35/100”
“I agree 3.5/10”
“A little cold, inconsistent speed, too many bad stops and starts”
“That welder wouldn’t pass the trade test”
“Not the worst I’ve seen… Rated 14ga out of 1/2 inch”
There’s porosity in them. The stops and starts are trash.”
“I would not def not use this with a 212cc…. Second picture top left there’s porosity and on the bottom right of the tube they didn’t wrap the weld around. It can start cracking upward especially from ****ing around and all the vibrations from the bike. This thing is dangerous. I used to do Harley frames. Please don’t use it or get it redone by someone who can weld.”

Again I'm no expert. I do see the porus areas and some of the stop starts could use work. I don't think i could do better. But I will say that you couldn't tear that apart. The parent material will fail before that weld will.
I rode my kart around with the front end tacked on. Didn't go anywhere.
Reddit is a tough place.

I assume most people who post “Rate My Welds” photos are posting beautiful rainbow TIG dime stacks.

Everybody on Reddit is online skill level 2000.

“First Time Welding, How’d I do. Go ahead and Roast me.”
