Juicing crop feedstock for ethanol - Page 14

 

Jim,

No one is responsible for my mistakes except me. Thanks for the axle
idea, but after CAD-ing it I think it is a step backwards for
construction simplicity and cost. Channel iron for the frame on the
other hand may have some potential.

Thanks,

Curbie

 


The disclaimer is standard on rec.crafts.metalworking when someone
asks if they can hang a 2x6 the width of their 2-bay garage and use it
to pull an engine. I toss it out preemptively now.

Personally I'd make the rolls from a discarded hydraulic cylinder with
end plugs turned from barbell weights. The axles could be cut from the
cylinder's piston rod if it's long enough or you find a pair. If I
couldn't get bearings to fit I'd make needle bearings from welding-rod
needles, boring the outer race to fit AFTER welding it to its mounting
flange. Music wire is another possibility.

The wheels, axles and needles are stainless because the platform
stacker lives outdoors, under cover but on damp dirt. The stock wheels
were hopeless outdoors.

Keyed shaft is convenient if you don't have a milling machine:

Taper-lock is an alternative for gear attachment that doesn't
absolutely need the key:

OTOH you don't have to buy too much of stuff like that to spend the
price of a lathe or mill-drill.

Jim,


I started a file with your links in it, just added this one too.

Thanks,

Curbie

Gee, all of a sudden I'm thinking of
using two railroad "trucks" on top of
each other. I don't know how you would
power them, but they have the
axle/bearing issue pre-solved...and are
probably reasonably priced
