My Compstar stroker crank has the reluctor tig welded on. The crank in the pic is just a stock LS2 one I'm practicing ideas on. I've been using OEM parts to practice on before I apply them to my nice parts.

Polishing the thrust faces on the connecting rods with a strip of denim. I was surprised at how many nicks and gouges there were on these. Titanium connecting rod thrust faces are typically coated because of way the metal galls itself. I will be be coating these shortly even though they aren't titanium just because.

To the OP. I noticed in post #201 that you edited for grammar. Your attention to detail in your typing is much appreciated. I am interested in this build and it means that I can read the updates without getting a headache. I cannot imagine how some can get thru life without knowing what simple words like "your" mean.

Got the pistons and wrist pins coated with microslick after sanding/deburring sharp edges, polishing, etching. I still have to coat the tops with the thermal coating. I meant to build a crankshaft polishing stand today but ran out of time. I will be polishing it to have a isotropic/non-directional finish vs the unidirectional one it currently has. Also tested coating a extra set of rod bearings with the mircoslick. They turned out really nice. Oh and I also put a very light chamfer in the small end oil holes of the rod.

Just thought the wrist pins looked cool after burnishing them. Kinda like a black chrome

Tungsten Disulfide .6 micron and Molybdenum disulfide 1.5 micron powders for the piston rings and other things.

Piston ring on the right has been coated with Tungsten Disulfide and ring on the left has nothing on it. The tungsten will reduce friction and retain more oil for a better seal and less wear.



These roller lifter bodies have been coated with Diamond Like Carbon (DLC) coating. It's great for wear but the coefficient of friction isn't as low as tungsten or moly coatings. I coated over the DLC with the Tungsten Disulfide. Notice how the one on the right has a slightly grey/metallic sheen to it now.



Roller chains have issues with squeezing the oil film out of the roller/bushing and between the roller/gear teeth. I coated the chain inside and out (even between the rollers/bushings) with moly/Tungsten to provide a solid film lubricant so it will always be lubricated.

Man, I sure hope you aren't shooting yourself in the foot. I hope you have had success with this coating(S) BEFORE.

Nah I've never used it before myself but tons of other people have..They are very common nowadays.

Bearing and valve coated with mircoslick and tungsten left .....uncoated valve and microslick coated bearing right

I can get a 20second spin on the wrist pin inside the piston if that tells ya how slick this stuff is.

Filed a groove to pressure feed the rear thrust face...



Here's a better pic of the uncoated and coated rings

If you're not careful this thing will be so friction free that once you get it started, you won't be able to turn it off....

LOL. Wooops LOL

Haha I wanna see if I'm able to turn over without a wrench and just my hand. I doubt I'll be able to but then I'd know that it's doing something
