Thanks,

They are made by a German company named Maedler, but they don't sell online, you have to find a dealer to buy through.

Oh well, I have scrapped the brass axle and roller bearings, the old one still seems to hold up for the new owner but I just wanted to make the axle out of steel and get the tapered bearings as someone here suggested!

I aslo have bought a house outside town and did a makeover on the garage that was in quite bad shape.

So here are some pics of the new crusher im building.

























Don´t laugh at my TIG welds, I have just started to learn how to weld with it !










This is how far I have got, I have printed the covers for the beltdrive and flywheel as well, next will be making the flywheel and mounts for the covers.




I also printed a little dust seal for the bearings as they are exposed to the outside.




And lastly, an after and before pic of the new shop!

Nice work as usual. I see you fixed the jaw teeth like we discussed last time. Hope this works out well.
I like seeing crushing equipment being built. I haven't had enough time to get more done on my stationary crusher.

Good to see you back it Kalle

Congrats on the house purchase & great job on the garage makeover, nice & bright in there now. Did you use LEDs for lighting?

Per your tig welds, they look better than mine, I still use my mig more than the tig. As Reg use to say, "gob it on & grind off the excess" ...though I think he does a lot less grinding off nowadays

Yeah, I had them made the right way this time.

I hope to finish this one and keep it, I will finish the crusher unit this winter and pick up next autum to continue with the frame, conveyor and feeder.

Thanks Joe,

Yeah, its a pleasure to work in there now!

No its regular armatures I have, I got these armatures for free from a friend. But I did went with another bulb (right word?) in them, these have a more white light then the regular used bulbs and are perfect for me.

Yeah you can always grind the welds but I think TIG welds are good enough looking even if they are quite bad, at least compared the bad MIG welds!

I really love my TIG welder, its so clean and you can do small welds, I just need to practice more to get more experience and less shaky hands!

Now it was time to turn the flywheel and the extra weight for the beltwheel.
I only had a 100mm chuck on my lathe and it cant hold pieces as large as the flywheel so I had an chuck adapter made by a local machineshop to get the boltcircle right and then I turned the last steps myself.
Now I can fit a 125mm chuck and this lathe will last me a few more years!

Here´s some progress on this project.

First I turned the internal hole for the flange mount on the spindle.


Then flipped it to turn the outer flange to fit on the new chuck.
I had 0.01mm runout on the spindleface with new backplate.


Here mounted and started to turn the flywheel, I had a runout on the chuck on about 0.03-0.04mm, that was measured on a drillbit in the chuck. Good enough for me.




And just a pic of my 10 year old chinese lathe, it has served me good over those years.








Also both covers are printed, also made on a cheap Wanhao 3D printer.

Fine machined and printed parts you got there. Have you evaluated adjustable bottom opening/distance of the jaws?

Thanks!

I don't really understand how I can do that? Can you explain a bit more please.

I see now you got a joint for a threaded rod as part of fixing the lower end of the moving jaw. Than one got the possibility for a adjustment, say +/- 5mm should do. manual adjustment is fine

Now I get what you was talking about, I thought it was the jaws on the chuck!

Yes I have adjustable jaws in the crusher, I can adjust them probably 10mm in each direction.

Made some progress on the crusher unit, its pretty much done exept from paint.

Now im waiting on some lasercut metal, luckily the guy who cuts for me had all the files that got lost when my harddrive crashed a few years ago.

Awesome work!

It was already looking great, but the printed guards make it look much more scale
