Anyone do fabrication or oddjob building?

[hex0rz]

Overall, a matter of issue has come at hand. In my beekeeping endeavors I have realized that lifting heavy things on consistent basis is, has and will take a toll on my back. Since then, I have set out to build contraption aid me in my endeavors.

 

But I have come to a sort of road block in doing so. I have some fabrication experience but not enough probably cut mustard. It's more due to not knowing what is at my disposal.

 

I want to build a hive lifter. It's essentially a dolly that I can use to lift for me and move  hives around with. It is also powered by a gas motor to aid in propelling it across terrain. Boxes get heavy. Like 80 pounds a box. Trying to design this unit to handle about 4 to 6 at a time.

 

I can get motor, clutch, drive wheel with sprocket, but need something to give a reverse feature. Anyone know where to source a small transmission to obtain this feature?

 

I'm also not sure how to size the motor properly and what gear ratios to have. I did a calculation online but it said it would go almost 30mph! I don't need speed. Max 3mph but lots of torque. But centrifugal clutches are 12 tooth. Maybe transmission can help me out. I also need to figure out how to make it 2wd instead of 1wd.  

 

If anyone's intersted I can show the build.

Could you modify a garden tiller?  Many of the have reverse and that wouldn't go too fast.

I want a combination of these two:

Old Snow blowers are also great for scoring parts

There's a little Dana unit I used in an offroad buggy.  Usually they're found in gold carts, but it's got forward and reverse, a 10.15:1 ratio (Can be had in other ratios), and a limited slip in it. Dana H12-FNR.
