that looks the same as mine and I think the rpm's will be better.
as for the crusher , that was supposed to be the next job until I saw your grinder attachment.
so you will just have to wait until im done with my grinder LOL.
good thing is now that the roller has been gutted of parts for the grinder I now have all the rc parts I need to make the crusher mobile, but still have to make some adjustable motor brackets for the crusher because I cant find the right size belts.
one day it will happen, but for now its summer and I really want to make a start on the cliff road with my grinder.

did a little more on the grinder,
I have shortened the collars on the sprockets to get them in closer to the head, and it should work better closer together.
and of course I have painted it before its finished, made a few brass brackets to hold wiring but a few more to do yet.

I think I will weld sprockets on and bore a hole through the sprockets so at a later date I can just put a shaft into the hole and add another set of sprockets if I need to.

more progress but a little slow.
made more brass brackets and fitted a solid line for the cables to power the grinder, and then run out of paint......

Need to do something about the wires on the bottom arm as I think they look like C@#$p.
also want to widen the track base by about 15mm each side, will be easy enough to make some spacers up and longer bolts.
But that's a job for tomorrow

today I finished the painting and cleaned up the cables on the bottom arm and installed two new toggle switches on the engine cover, 1 for the lights and the other for the grinder which is fused at 3amps.
also had to repaint the arms due to the new colour matched paint was different, spoke to the paint lady and she said sorry and gave me two cans for the price of one

Then I made up some spacers for the track bodies, 15mm wider on each side.
this has now caused me another problem, as it only just fits on the lowboy
I need to rewire the track motors now because the cables are too short, and I found out why I blew a track esc, wires way too short and shorted together

wider track setup



and the problem Ive created

well Im back,
had a small problem with a truck load of lightning .
basically it blew all the telephone jack points off the wall, fried the big TV and all other associated electrical things on that circuit, melted the TV aerials, toasted the wifi modem ect ect.
the insurance company loves me now, but at least nothing caught fire.

So, with no internet or TV I headed to the shed.

have been playing around with the grinder and need to make a few changes, I need bigger sprockets as the motor bottoms out too soon when grinding, also ordered a quicker motor.
Will try the bigger sprockets first and see what happens.
heres a quick video of the grinder at work, and a little taster of another idea I had, this needs some more internal work and more speed , but I think I can get it to work
