lawnmmower buggy

ahhh yea. lol. u got tools to do it there tho

Sorta better than home but still not everything lol

i have the engine plate off and mocked up where i need it. next time i borrow my neighbors welder ill mount up my mock engine so i can secure the engine plate. i am getting a little 90cc 4 wheeler that doesnt work for the front end suspension, steering, spindels and maybe some other parts or projects. pictures eventually

i have a job again start working tomorrow. so i might be keeping my mower and starting this again. i think i decided on kenda bear claws as my cheap tire swap as i cannot find ags in the size range im looking for... i want to tranny swap this and put a 5 speed under it with a pulley setup to try and hit 30-35 mph eventually if i get the chance

Glad to here ya got a job

Thank you. Its nice having a job again....

anyone have comments or suggestions on running a 4wheeler engine in my mini buggy? like what size would be good for a 1 seater? im looking for 30-40mph as top speed instead of 60-70 because i want as much torque as possible. and i might do that on this and build in a live axle into the frame. or another future build.

priced out tires. its 200 for 4 tires. kenda bear claws (23x10x10) and sti tech 4 mx (20x6x10)

To me I would run a 250 or bigger where you getting these tires

and im probably gunna save the 4 wheeler engine for a different build when im better at welding and have money saved up to do what I want. When I get to the 4 wheeler engine it'll be doing around 50mph on a custom steel tube frame with full suspension. Sticking to the twin mower engine with a 700

thanks to the infamous doc sprocket. i know have rear suspension designs made out
long swing arm in the rear with a frame extension up for my spring mounts. possibly dual coil overs one on each side. long springs mounted back for as much suspension travel as possible.
swing arm mounted on the sprocket jackshaft. 1" shaft for jackshaft with pillow blocks and probably flange bearings for the swing arm. or maybe something like this

You got it. You'll have to mess with spring positions for optimum spring rate. Largely depends on what you get. Cheaply, you could use the rear coilovers from an '80's motorcycle.

well i was debating on using atv front coilovers for the soft spring rate but as you said id have to play with it a little. there is a formula for it but i dont know the formula to find the proper spring rate. id also need a bump stop to keep from maxing out the spring and binding it up tho. another thing would be how to mount my front suspension. i think i have that figured out but i wont know till i have the buggy being put together and the front end off an atv to use. i want to angle it some to adjust for the forward stance of the buggy and to help with the shocks by rotating the assembly so the shocks lean back from the wheels some

You're probably best to mock up the stance, and then adjust the caster so that it will be about 10* off the road (NOT the chassis).

That's what I was thinking doc. Thank you for doubling on that for me.

Anytime.

Is there a gear box like a 700 I can get that may be high low gear also that way I have a wider power range depending on circumstances? Or would a 5 speed work fine?

700. Lotsa ratio possibilities, and you can remove gearsets, too if you wish to.

Ok because I want a first gear as low as possible. For the tough moments that I just need to crawl around. And a good middle range for mudding and high range for getting places

i cant seem to find a solid steel 1-1/4" axle for my buggy. just hollow tube. i dont want to spend 50$ to buy an axle and it end up not being strong enough for what i want so im going all the way looking for a solid axle.....

if anyone has any ideas... i found solid aluminum axles 1-1/4" or hollow tube 1/4" wall chrome moly axles 1-1/4"? which one would be better? or stick with 1" solid chrome moly

im looking here and there are a few selections available

original build is back from the dead. what would be a good starting size set of sprockets to run on a 3 speed 700 or similar model tranny/gearbox to achieve around 12-15 mph

my list so far. anything else i may need? i added locking collars and nuts to bolt the wheel hub on to my list

did you add money?

thats on another list thats being added up. i cant make a total till i get the atv that im going to chop for this. ill add the current list tho
