Welcome back and glad to hear all is well after the fireworks and all.

The grinder definitely needs larger diameter sprockets but I don't think you'll need to up the speed. Can you also maybe change the bottom of the drive from a flat surface to something more knife edge or tapered a bit.

How much larger of sprockets are you thinking of using?

The hammer, But you need more speed there for sure..
Keep it up, looks great!

cheers Mario,
bigger sprockets are a must, but cant change the flat surface as that's the bottom of the gear box.
I think I will look at another 10mm in diameter (60mm), I will see what they have on their shelf and its gota be cheap.
and the hammer, yes there is a lot of changes needed.

had to rebuild the road I destroyed with the grinder, so took a little time and had a play while thinking about different ways to do the hammer.

It's kinda sad to see this thread not updated regularly anymore, you have a lot of innovative ideas built with basic tools & good ol' fashion know how... hope to see you back 'er someday soon Andy, long overdue to see that tracked crusher in action.

hi Joe,
yes way too long but with starting my new business running a small excavator and truck theres just not enough time in the day.

thinking really hard about employing someone to help me out so I can get some more family time and of course play time.
The crusher can move under its own power but I need to redesign the conveyors as there is not enough clearance underneath .
Just need to find 10 hours and she will be finished.

hope fully things will slow down in winter and I can finish it.

How’s it going Andy ? Haven’t seen you online in a while. Had any time to break out the rc’s ? Roadrunner looks and sounds great

Hi all and merry xmas and a happy new year.
Im still around and even charged some batteries for a bit of a play, but that never happened.
things are getting more organised so i have some spare time in the day.
because its summer here Ive been getting around as much as i can in the roadrunner and doing a few hot rod shows.

Skeeter , from memory the geared motor in the dump truck was around the 30rpm
range.

cheers andy

Thank-You, sir for the info.

I have GRU in mine for now, but IDK if the other builds are worth the $$, when one could simply place a gear motor on it, & have the SAME effect for far less!

So glad these photos weren't lost. Love the changes the 4200 went through to become the monster it is today.
