Re: Volvo G990 Grader
Some more circle making pics. To start with a "quick and dirty" jig for adapting the bracket base to the radius of the circle ring.

Re: CAT 374D L
I see, its a bug and not a feature :D Well, in any case, the chain plates might dig in a millimeter or so (actually half a millimeter if you have the 6 mm pitched chains), but then the rollers start...

Re: CAT 374D L
Impressing as always! But it looks like you let the chain actually slide against the housing walls? Never seen that before. Don´t you think that will create noise and an aluminum slurry?

Yep, I meant the length of the neutral axis ;). Btw, what dimensions are we talking about in your case?

Re: Volvo G990 Grader
Can sure agree on that. I actually calculated and marked the length to cut before bending. The first cut was just a bit too long (and luckily not too short).

Re: Volvo G990 Grader
For the wiper I expect some experimentation to be necessary (since plastic kind of yields to the cutting tool). I´ll start with PTFE and hope that I can somehow produce a working wiping lip.

I´ve found another foundry to entrust with the next, much beefier part(s). Hope they´ll do better.
In the meantime I´ve started making cylinders. They come in two rather small sizes, namely 10...
