Nice skills. It's a pleasure to watch a master at work. Reminds me of my late father, he was an RAF trained engineer & never ceased to amaze me & many others with his skills, wisdom & adaptability - mostly he used to say it's just common sense but, from what I see that's in short supply these days ! He liked draper gauges too - great quality, highly underrated. Best wishes Paul UK.

Your level of skills, experience and attention to detail is simply outstanding. After watching your origin video I have an even deeper respect for you and your wife. Y'all are legitimately self made people. Y'all's financial methods are top rate.

Pinky in the air while tigging . . . . gotta keep it classy. Seriously, that is really neat to see. I went to trade school in N.E. Ohio back in the eighties, near Akron. So Summit racing main headquarters and Original store location was about a 30 minute drive away. You could buy a SBC cam, lifters & double roller w/a multi cut keyway for $119.95, all day long. . . . _OR_ . . you could go to any number of local speed shops and get "renewed" lifters and a welded/reground seasoned cam for $50 bucks. A "performance" timing set from Napa was $40-ish.

[@powellmachineinc]

Facts

[@ericstalker7973]

Back years ago I learned how to check crank shafts for straightness. Surprised how many were not straight right out of the box. Especially the straight 6 crank shafts. We would put the crank in the block with the first and last main bearings. Then set up the Dial indicator gauge checking the center main bearing surfaces. Slowly rotate the crank shaft and bring the high spot up then take a Minny sledge hammer and tunk down on the web of the crank shaft. Slowly rotate the crank shaft and check for straightness. It's really cool, usually only need one tunk and the crank shaft is nice and true again.

I spent a few seasons as a crane follower at a steel plant and ever since watching the ladle pour the hot metal and see it flow thru the forms and turn into a steel beam as it came down the line before being chopped to length.

Every time you stand a cam on end, my ass puckers up and clamps shut. LOL. I knocked a cam over and broke it one time. I wasn't really in danger of being fired but his look of disappointment rivaled the look my mom could give.

[@powellmachineinc]

Lol, luckily steel cams don't break.

[@ArcAngel572nc]

I love TIG welding too! Its very hard to put the torch down once you strike the first arc!! Its very addictive for me. I dont want to stop once I start. Ill look everywhere for an excuse to keep welding. 👍

[@davidholcomb9961]

Reminds me when i used to rebuild Torque converters on old WW11 lathes; bolt them up to big old face plates and center the front hub and cut the weld until they would pop; then take a mallet and tap on the housing to ease the 2 halves apart. That's where i learned the basics of machining, welding and fabrication. That was a damn good job! Also learned the art of using a dial indicator to measure how far to run the tool post in before turning anything to size because the original lead screws and half nuts were replaced with threaded rod and a nut welded to center of the carriage! Yeah, old school, red neck machining at it's best!

[@The340king]

I have a 60 mm roller cam that got dinged when a wrist pin broke. It looks like it got a double line groove from a rod or the lifter in one lobe. I haven't checked the straightness yet. I am not sure it's the right grind for the application though as it appears to be a former Craftsman Truck engine. I may call you to discuss if the machine shop doesn't have something better. They were an ARCA builder in the past.

[@powellmachineinc]

Definitely, lmk

[@jeffreydurham5342]

You are exactly right, (as you know) let the lash get loose enough and that lobe is in its ramp to open the valve and smacks the shit out of the lifter making those marks on the lobes

[@georgecutler920]

[@powellmachineinc]

Cam grinding is almost voodoo to me 😅😅 I understand how the machine works but there is a lot of setup that I haven’t seen yet. I would love to see a cam getting ground starting from the very first step of setup.

[@TurboJohnRacing]

Crazy how hitting a cam or crank on the low side makes it spring back! First time I ever helped my machine shop buddy straighten one of my cranks was wild! Would be cool to see how the cam is setup so that the stone follows the lobe. How much can you change a cam on a regrind?

[@powellmachineinc]

It depends on core matl, current specs, ect, but it's easy to shrink duration and add lift, we can add duration but normally more than 10 degrees is tough

Can you repair some damaged lobes on a m278 engine. Mercedes v8 turbo twin overhead cam. Lobes have damage from failing roller rockers. Probably could just do a regrind.

[@powellmachineinc]

I would have to make master plates, so it would cost more than a std regrind

[@TheJohndeere466]

I would think you would want to weld that in some wooden v blocks and then use a magnetic ground right on the end of the cam. You have to be arcing through those v blocks onto the journals the way you are doing it.

[@powellmachineinc]

Na, good connections don't "arc"

[@bobhudson6659]

Questions for you. How many times do you think Daniel would have welded cams? 2nd. Do you not think Daniel would have noticed if there was arcing on the main journals if there was a problem? How about you give him credit for knowing what he is doing. Daniel also has to warrant the work he does. Would you warrant the work if there was a chance of arcing? Come on.

[@TheJohndeere466]

@@bobhudson6659 I've seen guys weld on a lathe while grounding to the lathe and I've seen what happens to the bearings. It puts little arc spots all over the bearings. Granted this is welding while the lathe is turning. I know I wouldn't do it and I've been a machinist for 40 years

[@MajRAV]

I have probably a stupid question, please forgive my ignorance. If you use weld that has a higher hardness than the lobe, say 58 hardness weld on a 50 lobe, does the original material on the lobe not wear faster than the repair spot? If the original material were to wear faster, then would the lifter eventually have an odd wear pattern?

[@bobhudson6659]

Ask yourself, why would Daniel weld on 58 Rockwell C material on a 50 Rockwell C material camshaft in the first place? He's been doing cams for a year or two so give him credit for some common sense - and experience.

[@MajRAV]

@@bobhudson6659 for sure! Hes an expert, full credit. I know absolutely nothing about machining, thats why i asked and mentioned I'm completely ignorant on the topic.

[@slightlycynical]

I'm a noob and I know nothing in comparison to video creator. My first thought when seeing this; Shouldn't you support the cam or crank directly underneath your weld point, so as to not cause warpage? I'm just a noob with curiosity and new to personally rebuilding engines. Genuinely curious

[@powellmachineinc]

No, , we concentrate the heat in a very small area, so it isn't "sagging the cam.

[@jmflournoy386]

we ran rollers on lobes much narrower than those, could you have narrowed? did you have to make masters. Some of the new CNC grinders will digitise a lobe and grind from the lift table (sigh)

We put our own profiles on it, I haven't seen a grinder that would digitize a existing lobe,
