👍😎 Great video Charlie. Hey IMO if its within .010 thats close enough to warn you when youre getting to a reasonable limit. Just my opinion of practical useage.😐 I bored a SBC once and on the race track it blew a nickel sized hole in the cylinder wall.... Which measured .060"... A thin void that was undetected... Sleeved it.
I need to get a good ultrasonic thickness tester. I am doing a head for a big cube application and I went thru into the coolant jacket in a few spots getting the throat size up to 85% oh well. Just have to weld it up. It is feeding 130cubes thru a 2.25" valve so it needs what it can get.
Cool presentation, thanks. Have you ever tried all purpose grease instead of your gel? I like it because it doesn't rust out what it touches and can be reused over and over. Just have to calibrate with it and at least it works for me.😎👍
@@servediocylinderheads If they can sell cell phones pretty cheap, the electronics in a sonic tester should be a reasonable price... But they don't sell many, do they?
You usually get what you pay for especially on equipment but I watched a documentary recently on the true cost of making some of these electronics now🤯it was dirt cheap! Like the cost of a new iPhone…downright upsetting to find out. Not upset at the poor Chinese people who slave away to make it either- THE LOGO MARKUP! 😖
Great video Charlie. I have a PR8 I’ve had for years but haven’t used a lot because I was not very confident in the readings I have gotten! Is there anything different you would do on aluminum?
Aluminum needs to be calibrated for aluminum. It has a different ultrasonic speed. I go back and fourth between aluminum and iron alot so, I need to calibrate every time I change heads or intakes.

I never had luck with sleeves. Thanks
Thanks for the demo Charlie, very educational 😊
Glad you like it. Thanks
good added info

Good stuff

I don't think I have. What I don't like about grease is it is like roofing tar....gets everywhere!
@@servediocylinderheads
No that's silver antiseaze that does that. LOL 😂😁👍
Charlie have you seen the new ultra sonics you can buy for 100 oe so dollars
I'm curious how accurate they might be
Mine was more than 10 x that, but that doesn't mean the cheap ones will not work. I have a cheapie somewhere. It was horrible.

@@MidnightOilsRestoration I agree, I would like to write that I never regretted buying high quality stuff. True, I did need to save up to get it!
@@servediocylinderheads I absolutely agree with you, buy quality-buy once!
👍💪
Thanks Charlie. You are a good teacher. Have you seen the latest DV and Eric W. Videos?
I have. I like them both so I have no comment.
@@servediocylinderheads I understand for shure. I think the same.. DV invited him to his shop all expense paid.
@@dondotterer24 I don't see that happening. Eric has a family to support.
@@servediocylinderheads that's true

Hello Charlie , I was wondering about mission imposible 318. Is the project still going on? thanks
D.V. and Andy have all the parts I worked on. I have not had an update. I have asked if I could help anymore. Thanks
So what do you think is a good rule to keep as far as thickness is concerned? 0.100?
Yes. Thanks
.125" between bowls
What sonic tester head is that?
Good question. 5 mhz, 9" shaft 1/4" diameter
When I bought it the engineer said it would do iron and aluminum. Thanks
