    Honestly, Steve is probably the perfect teacher in my mind. Just gets to the point, No unnecessary blah blah. I could learn very quickly from Steve.

    I have been taught , you weigh the big end ,and make sure all weigh the same by grinding them to the lightest rod, then weigh the total rod and grind the small end to make them all the same weight. It seems to work out the same as yours but is better because it eliminates one process and is more sure . Hope this helps someone . I run a balance machine many years ago and learned all macines in a several shops.

    I used to balance jet engine rotating assemblies and this really brings back some good memories. In some instances we would actually introduce a known imbalance in centimeter grams, then spin the assembly. The computer would provide a solution set with PO1-P07 balance weights that would thread into the rear spinner cone. We would measure the imbalance in amplitude of mils (0.001") which is where the fan blade would oscillate off axis. Could even use the equipment to determine individual frequencies of components that ran off the accessory drive gearbox. If the imbalance was too great the engine would require a complete fan blade restack. What made this whole deal so challenging was it wasn't just the weight of a blade, it was how far from the center of the engine that weight was located. The further away from the center the weight was located, the more influence it possessed. Even though designed to be identical, every blade was never the same.

      When I first started listening and talking about Steve people on the internet did nothing but trash him. It used to piss me off because some people that didn't know better used to listen to the idiot trolls that used to kiss another builder's ass. Thankfully Steve got the last laugh and I'm glad he still ignores the haters and shares everything that he does.

      @@Matty.Hill_87 it’s crazy how many people will play make believe in UA-cam comments. Especially when it comes to heavy equipment/tractor trailers, they’ll say some of the funniest stuff too. I had one guy try explaining why it’s hard for him to go from the low side the high side because apparently he could only flip the range lever while he was shifting and not while it was in gear. I’m assuming he thought that would change the gear because he saw a guy in a 13 or 18 splitting the gears on a video. Then I got guys in company trucks try telling me their autos are faster because they never “miss a shift” lol it’s the kind of stuff I used to think as a boy watching my dad drive his semi.

      @@oldandboosted . People Should run a engine catch tray with deep sides that bolts to chassis of the car. Engine diapers are one solution, but if oil is spilt or a oil pressure line is leaking it is way harder to diagnose because you can not seee the lower section of the engine. Also if they get soaked in engine oil they become a fire hazard. Check out Steve's latest video when al 8 connecting rods disintegrate on the engine from the Bosstmaster2 and it puts massive holes in the oil pan. The catch tray catches everything and does not oil down the track or put oil under the rear tires. Plus a engine diaper also makes the engine run hotter. It is worth while building a good quality engine catch pan.

      @@MJTAUTOMOTIVE I agree but not every car can run a catch pan. Sometimes the engine oil pan hangs down below everything else. If you cannot run a catch pan, then you must run an engine diaper. I agree that catch pans would be better but an engine diaper is easier for most people. Steve Morris's car is basically a pro mod. It was built to accept a catch pan.

      @@oldandboosted I agree that all vehicles are different. but a catch tray can be custom made to suit just about anything. even if it id only 3/4 of a inch from the oil pan, it is still a better idea than a diaper. Engine diapers are a pain to get to fit correctly. When Running that sort of horsepower the vehicle should be modified to make a catch pan fit. If you have a diaper and the engine lets go, you have to not only repair your engine but also replace the diaper. once they get oil soaked, you can never get the oil out of them. I had a vehicle in for a tune fitted with a diaper and it caught fire on the Dyno. The owner had a leak on a turbo feed line before h
      He bought in to me and said that he had cleaned and degreased the diaper and the engine bay. After a couple of low boost pulls i started to see a little bit of smoke. Once we stopped and shut the vehicle down the smoke coming from around the lower part of the engine just below the left hand turbo manifold, up it went. It was not big and we got it out very quick, it did not do any damage except burn a little paint and scorched the sheath on one of the battery cable wires. I think it might be just Me, but i do not like them. If that would of happened on a full pass a the track with a lot more heat, we would never know what would of happened. So in other words I manufacture and fit a lot of catch trays.

    The likely reason that the temporary test weights show as being too light is because they were placed inboard of the counterweights instead of centered on them. The further in they are the less their weight will impact the end balance. If you wanted test weights that better simulated the effect of the mallory metal you could use magnets. If you place half on each side of the counterweight it'll better simulate weight placed in the counterweight.
