You, the man, Daniel! So, many machine shops in eastern N.C. only do basic stuff. Surfacing heads flywheels, etc. Maybe, valve jobs. Ask them to align hone a block or regrind a camshaft. No, were not set up, to do that. What, a shame. The craft is dying. Thank you, for what you're doing.

Doesn't change in cam base circle call for different length pushrod ? Longer pushrod will add weight that valve spring must control. Spring Shims should fix that. Those costs would be add'l to $300 regrind fee.

Thanks for explaining the cam grinder in more detail and showing the cam plate function. Really cool machine. I take it it's an older machine?

[@powellmachineinc]

Yes, it was made in the 50s, we completely rebuilt it 8 years ago

[@diggy-d8w]

When I first started watching, I didn't realize how expensive these "cams" were. The Harley you worked & mentioned like $4,500 and I was taken aback. So the strength/hardness of these cams is such that they are an expensive part, hence all specialized machines to save what can be saved & to get them into as close to specs as possible. When you mentioned the "hardness" of the lifter vrs the camshaft that caught me - how would anyone be able to trust what a website/amazon says about this? If I were racing I'd have a way to know but I'm just a dumb guy who wants to know it's right.... exceedingly difficult for folks like me. I guess that's where you come in. peace Dr Powell

[@powellmachineinc]

The Harley deal that was 4500 was a billet crankshaft, not a cam, but we do billet tool steel pro stock Harley cams that are real pricey also

[@diggy-d8w]

Yeah, I've just learned about how they make these parts & the difficulty of that process along w/ the quality. Prior I thought these things were cheap & just poured into molds just as fast as they needed? For you to own equipment all aimed at repairing these cams it tells me the value of the part. It's fascinating to see you reading the surface of the metal as you speak about things that might cause what we're all seeing. I'll be here for the next one.... thank you, Sir

[@GeorgeFarahGNR]

Wow why was lifter not centered on the lobe, looks like the cam was back too far, any signs of cam hitting cam plug?

What's typical cost of regrinds? Just to compare differences in buying a new cam. Also can you cam Dr a cam that has larger cam journals? I have a few from years past I think they were old Nascar cams if I remember right. I'd be curious to know their lift and duration.

This is kinda a dumb question but this channel is one opinion I would trust….if a few cam caps are flipped upside down as in the letter aren’t running the same way as the rest…would that cause any wear/dmg to a cam?

They need to be on in the correct location and direction, as they were bored from the factory, so you would have alignment issues

No

[@jeffreydurham5342]

I believe the reason being that you wouldn't want one lobe being different. It would be very difficult to regrind one lobe to match the existing ones on the cam. If you had a master that matched the existing ones you still have a smaller base circle.

Not normally, we manufacture new camshafts, but every now and then someone won't pay there bill and we sell there cam

[@olduhfguy]

I gather that the only difference between grinding flat tappets vs rollers is how you dress the wheel. Since the name brand grinders are going to a CNC grinder that can allegedly make a cam from a blank in 15 minutes, would you say doing it the 'old school' way is better or worse than a fully automated shop ? I'd like to believe you can give a cam better QC than someone throwing a cam in a machine, closing the cover and having a coffee......
