That just amazes the hell out of me that you can take a bent camshaft put it in the press bend it back and then put it in the cam grinderhit it with the air hammer ping it a few times to straighten nit out and it dont crack or break in half. I have seen camshafts that were in an engine that had a lot of damage to it and the camshaft was broke in half. Just amazes me that you can actually do that to any camshaft. That is real cool to see it with my own eyes because if someone told it could be done i probably would not believe anyone. Awesome nice job great work bud. That is going to be one happy customer thats for sure. Every time i watch your videos i learn alot and thats no lie.
Thank you again for spending your time to put together another informative video on how and why ,l look forward to these videos plus it's saved me from making mistakes on my current rebuild, l always look forward to your videos much appreciated Roy from oz
That's a lot of work, cool how you just put it in the press, pump pump, pull it out hit it with the air chisel, wamo fixed 😂 great job, thanks for sharing, all the best to you and your loved ones
28:52 I really like it when you use the machinist blue, we can see where it takes away material easier when you use it. Please use it on the videos more like you did a few of the others, also zooming in on the lobe would be awesome.
I ain’t never straightened camshafts, but, spent a fare amount of time on a press. I’m thinking a manual press, either a heavy arbor or a hand wheel - screw type, would be less hit or miss then y’all’s air / hydraulic press… Thinkin’ I’d give the customer a disclaimer on that one, in case it broke, down the road, for all the straightening y’all had to do, to rescue it.
How often does a cam "blow up" in the press, and how much does it hurt when you get hit by the pieces? This has clearly happened at least once to you, can tell by the way you stand to the side and as far away as possible.
Tell the shop to tell that dude it's a race engine. Those are to come by. Don't buy 1, ya buy2 if that's your combo you usually run. That way this don't happen. Or at least 1 in repair while the other one is running.
How deep is the hardening process? I can't keep a crank bearing on a 10/10 grind, wondering if its because the nitriding is broke through or if it's a balancing issue.
No, that's a wives tale, the nitride is gone at .005 or .008 probably, think about cast cranks... there not hard, also we've turned thousands down with no issue's, nitriding is just a "extra layer, the crank is still hard,
it can't tell you anything unless you do it enough to 'calibrate' yourself to dial in a bunch of 'spring back'. (and that makes it even more nerve wracking)
@@earlbrown both designs have ramp. The rough grind before we receive it, is the difference. Check out our "Powell Cams" channel, we explain all this in detail.
hey i got a black and decker valve refacer,yours looks like a Sioux,i got the same rimac spring tester. how i just watched your previous post good info,thank you
