Yes, that is a Ryobi grinder. I bought it because HD wouldn't cut 20 foot rebar and I had a charged One battery in the truck. One less cord on the bench.

Only have one front axle as these purchased parts are 416 stainless and required a redesign as I won't weld such a part due to stress and material. Sure, it could be done but the part is designed and purchased so use it as intended. I did one steering knuckle and it worked so the team will use the university machine shop to replicate.
I also fabricated the knuckles from A36 1/4" plate. Fun welds for a change.
The hardest was the rear triangle. Laid it out, jigged the dropouts and tacked it up. After welding, the wheel dropped in with NO cold setting of the spacing. 135mm on the money.
