Did you find drive sprockets or build them yourself?? Tracks are from a??
My mini dozer build
- Thread starter OTHill
- Start date
I looked for sprockets to buy but couldn't find big enough ones so I cut my own. My plasma won't cut 1 in material so I cut 1 main complete sprocket out of 1/2 in plate and another rim also out of the same. Welded them together to make 1 in.thick. Same with front idlers and all the rollers. Tracks are 300 mm width by 52.5mm pitch and 74 link if I remember right. They fit numerous machine
Closer view of sprocket build. I used free software called sprocketeer. Very easy to design sprockets of any size or pitch. The trick I found out though is that a 52.5 mm track takes approx.a 50 mm sprocket because the thickness of the track doesn't allow the track to hinge on the center of a pin. I cut 3 or 4 trials out of 14 ga.before I got it right
Gonna share a little more of the start of the project which I should have done at the beginning of this post. I've thought of a project like this for a long time so when I ran across a fire damaged portable welder with a mostly undamaged Kubota engine for a reasonable price I bought it. A beautifull starting and running engine with 3400 hours! Next problem what size? I surely wanted it big enough to ride comfortably and do some usefull work. The engine had the front grill intact and looked like it could have dimensions to start with. I pictured a machine maybe 4 ft.wide and six ft.long. So sat down with Corel draw on my computer and came up with the following.
On the left is the size and shape of the original grill with some tracks sized to what I thought would look right. Now don't laugh anybody!! On the right I progressed to a side view with a six foot operator in block from to make sure he would fit. So here is how you start designing a dozer when you don't have an engineering degree

You don't need to have a degree,,, if you look through history many, many people dropped out of school yet did great things. Some people will even argue that a engineer degree will quash peoples thought process and have written books about the stifling of great minds, that a university will do. Whatever the case, I've designed many things by looking at current machines and made improvements. Or at least attempted improvements. 
Where are the tracks from????

Thanks AlyA. I've never even wished for a degree. I've just happily invented all my life. I've always detested things that were hard to service but low and behold by the time I was done crowding the hydrostatic pump and motors into to small a space I've come close to doing it myself

Camso and Soucy are by far the largest rubber track builders in the world but the real question I should have asked is "what machine are the tracks made for?"

Late to the party here but did you complete a blade for it or other attachments or implements? The machine looks great.
Working on a blade right now. Gonna be six way hydraulic. Bought a 2 spool joystick already for lift and angle and need to get a solenoid operated diverter valve for the tilt.blacktruck said:
A little more progress today.
Some shots of A frame and mounting.
