What to build?

[mechanicalbrain]

well you could do a remote control lawnmower or a nice control box for robots (the one im doing is NICE it does everything and a bag of potato chips).

I would make a motorized Lay-z-boy. In fact i think i just may. But yours can be powerd by a weedwaker...which would be fun. You could make it R/c which would be funny to watch people sit in it.

thats just creepy ive had that exact thought i even looked up cheap chairs. you know you could take a old robot and bolt it directly to a chair. asuming the motors were geared right.

enter a featherweight robot wars competition...
(we did this and had a robot called 4am. Cookie for guessing why )

Okay. I've got my 3hp horizontal lawnmower engine running quite well now. Now I just need a project to build around it.

I was thinking Gokart but it is a little too small don't you think? I'm thinking it wouldn't be fast enough or powerful enough.

I was thinking big RC Car but it is a little too big (steering and brake actuation is the problem, I don't think even 1/4 scale servos would do it would they?).

I suppose I could make one heck of a scooter (stand on style) but again brakes would be a bit difficult to implement

Do you think it is powerful enough to hook up to an alternator and make a decent arc welder (like 130 amps)? Or would it kill the engine every time I tried to strike an arc?

I was thinking of making a generator but the power doesn't really go out very often, and when it does, it is usually back up in <35mins.

What are your thoughts? What should I do with this thing? I don't want to have to do any machining, but I do have limited access to an arc welder to lay down a few welds if I need to. I'd like to do this project on the cheap, but I am willing to spend a little bit. So, what should I do with this gem of an engine?

ups ? lol
you could put it back in a lawnmower and enter lawnmower racing ...
i'm stuck for ideas...
