I gotta try to find this somewhere else.
Still looking but here’s another one.
Some Facebook videos can't be shared due to privacy settings on their end. 
Man it was a good one. I shared it on my Facebook page but couldn’t here. Bummer.
And I haven't figured out how to capture the videos to replay elsewhere.
Yep. Above my pay grade. My youngest would just push me aside and clickety click and it would be done.

What are they doing welding a broken cam or building up lobes to grind them down?
Repair. A lobe went flat (possible roller lifter failure)
I'm going to talk to my welder and see what he thinks.
I find this very interesting.

I wish you could see the better video that shows the welding

I'm curious about cost. I have a bbc roller with a couple serious divits from the previous owned who spun it too fast, with too little spring.
Guaranteed repair for half the cost of a new cam? I'm in!

My local cam grinding mob has been doing this for years. I was always hesitant to try one that had the lobes built up with weld - i always stuck with what could be ground from what's already there but plenty of people seem to be running them without issues.
Sometimes scrolling through the posts from a smartphone thumbs accidentally hit disagrees or thumbs downs and we dont realize it. Its happened to me quite a few times.

Hard face rod? I didn't attempt to watch the video. Just find a guy that welds up earth mover buckets or something similar, lol.
This guy used a Tig machine

Done right there's no reason it shouldn't work and be reliable. Cranks get built up by welding and ground all the time. Probably more often in commercial/industrial applications where time is money. Amazing what some guys (not me) can do with a welder.

When my junk **** Crane lifters were failing at a rate of 2 lobes per pass, I was having Ken at Oregon Cams weld and regrind the lobes.
Never had a failure with a welded lobe. Plus, he was doing dozens of blown alcohol cam repairs. Those guys are murder on valve train.

What did he charge, compared to a new roller?
Is he local to you.

IIRC, it was 125 bucks for the first lobe because he had to weld it up and then copy the lobe. Unless he already had a master for the lobe. I was using lobes he didn’t have a master for.
After that, it was 75 a lobe to weld and grind. BUT…that was almost 20 years ago now. So I’m not sure what it costs today.
It think it was on the comments on the drop-down menu where I saw 50.00 per lobe. I have a small block cam I would gladly pay that to fix the one lobe.

WTH?? Did he drop his prices??
$50 a lobe for welding and $150 for grinding to profile, was what I saw in the video where he was doing a cummins cam.
