Has anyone ever tried spot welding the engine to the frame instead of bolting it to the frame?
I'm not sure what kind of metal the happy time engines mounts are made of but I would think spot welding it on (rather than bolting it on) would make for a much more solid mount . If anyone's ever tried it I'd like to know how you made out.

dont weld anything, theirs no need to, the bolts hold fine. I think the mounts are aluminum so welding might be hard as well. Dont weld it!

no welding here please -- there are many reasons -- just a few are

the different types of metals -- bicycle frame metal type -- engine metal type

different thickness of metals to be welded

vibration would crack through these inferior weld points

welding could weaken the frame

question -- would you want to weld your car engine in place ?

I am thinking you would have to be an experienced welder to lay down some near perfect beads to keep it from vibrating loose and cracking the welds.

Not sure about spot welding it, may need to be tig welded??

Any professional welders on this forum have any thoughts?

welding it would permantly attach it to the frame material. the welds arent going to break if there done OK, dont have to be perfect, but when you weld the material around the weld will become weaker. this weaker area is where the frame will break or tear. your motor will still come loose when it tears away from the frame

just two -- of many good points made

bottom line is --

welding engine to frame is what this one time welder would call

VERY SILLY IDEA !!!

when that engine breaks off -- it sure does make it hard to ---

Yeah your right, car engines and motorcycle engines are not welded in place.
Good point.
