I am going to feel the ground shake all the way up here when you finish Black Betty Great Video Wayne Thank the shop for the great info and have a great time with MR CW
@TheDieselStop i understand that he knows what he's doing and i understand that those areas don't matter as much but it seems to me that if there were an area that had a thinner coat it could chip/peel. not meant as an insult in any way
@ils360 Coating the tops and skirts normally runs $36 per piston. The main bearing set for a Cummins cost $50.40 and the rod bearing set cost $28. The turn around time is normally 2-3 days in shop. I know you have that bike project & it might be different in price on smaller pistions but I dont know for sure. You should just call them.
@michaelovitch The coating on the piston skirts is normally about .0007" per side. The bearings are normally .0003"-.0005" per side. You should let you engine builder know this and he can tell you if it's going to cause clearance issues. Normally if your running on the fat side then don't worry about the coating, but if your running on the tight side then you want to take the coatings in to consideration.
it looks like all they are doing is a 2 stage bead blast on each of the pistons and then putting a primer and a finish coat on them and baking them in the ovens to make sure it stays and cures properly , i know the "trade secret" is in what's actually in the stuff they paint it with but with the main ingredient for the tops of the pistons being ceramic that part shouldn't be too awful hard to figure out either. what's got me puzzeled is the piston skirt coating (1st paint job)
@dilauroj94 I blasted and painted for a few years. I read Waynes comment... I was just stating that he touched it AFTER blasting which in my mind is worse than BEFORE blasting as you were questioning. I dont know the specs of their coatings so im not gonna argue, maybe your skin oils are efficiently removed when he warms them up (which i doubt because he is just warming them so his coating adheres better). Anyways, enough spam from me lol
@VicGord WTF??? I just called him and had no idea he was stopping by. Thank you for letting me know because he damn sure didnt. He was in AZ last night so he will be here in a day or 2.
it doesn't look like he takes a whole lot of care spraying the skirts in the vid... seems like he skimped in the wrist pin areas... not that the coating does a lot there but it would help keep from peeling if it had a very uniform coat. but it might just be the video making it look that way
i have a question. he put the pistons in the bath to remove all the oils and solvents that were on them, but he also touched the pistons with his bare hands. wouldnt this put finger print oil on the pistons?
@kingkongbong123 First off this is not paint. If you did watch the video you will see that the skirt of the pistions were not touched after blasting only the pin boss area that does not matter. You should had ask if there were any other steps after blasting before you started your rant & you would had found out there was steps that nobody got to see. I would had said the same thing if I never got to see the process. There is alot that you guys did not get to see.
@kingkongbong123 now i didnt say all that. maybe youre in this business but im not. i was just asking whether or not it made a difference, bc i dont understand or know all of the science behind it. and wayne left me a comment back, READ IT!
@dilauroj94 I fully agree, he also touched freshly blasted steel, thats even more of a no-no, if fingerprints can cause epoxy coatings to fail, i dont see why this would be any different. He should strive for a little more perfection than just masking it properly... Not hating but this guy should put his money where his mouth is. Cool videos though!

Nice Video...Can't wait to see the next part! We're all interested to see the final product.

Amazing everything there is hands on no mechanization processes. A quality job is being done. Curious to see how they do the bearing shells.
@TheDieselStop i understand that he knows what he's doing and i understand that those areas don't matter as much but it seems to me that if there were an area that had a thinner coat it could chip/peel.

Very interesting series on PolyDyn coating pistons. Thanks for sharing !!

@KrankieV2 The the wrist pin areas do not matter as much as the skirts. He has been doing this for 40 years and knows what he is doing.
nice series of videos Wayne, awesome stuff man.
@dilauroj94 Keep in mind that the pistions are blasted & put in the cooker after that.

@POLYDYNTX7
Ok !

@ils360 The link for PolyDyn is below the video you can call them if you would like.
Sweet video can't wait for part 4.
What is the thickness of the coats added to the pistons and do this change the preconised clearances in the pistons/engine block matching ?

That's alot of masking. I hope its worth it. Thanks for another cool video dieselstop.
Very interesting process
@KrankieV2 I dont know maybe PolyDyn will reply to you I am not sure the reason for that.

So that machine he put his hands into is basically just a fancy sandblaster?
How much extra heat will the ceramic coatings be able to withstand? Thanks for the video!
@TheDieselStop im thinking it wouldent hurt to get the piston for my motorcycle polydyn'ed
@tedhaze1 Thank you.
excellent vids man
@TheDieselStop how much was it for one piston if you don't mind me asking
where would i go to have somthing coted like this dose he have a online place?
That's sweet

@gogmorgoaway Yep called a blast cabinet.
