HOW to balance an aluminum driveshaft

25 years as a machinist here. A dead blow tap like you're doing on the chuck key isn't likely to cause much trouble, but the reason why it's a no no to use a hammer on it is because the scroll plate inside the chuck is usually cast iron. It's the part that moves the jaws in and out. What I've always done is used a pipe as a cheater bar on the chuck key. Use your body weight and you can get some real holding power in. Keep up the good work!

But it’s rubber? If I put all my body weight it’s still not enough, as you saw in the video… - plus our company makes our balancers and they said it’s fine so I don’t understand …

@@darklydemons4497It's not the issue of your hammer being less hard. It's the shock load of a hammer blow on the cast iron scroll plate inside the chuck. It's a big swirl looking thing that has slots the chuck jaws ride in. Cast iron is brittle. Often times the scroll plate followers are hardened so it's functionally the same as driving a cold chisel into it. And your body weight is absolutely enough if you use a large enough mechanical advantage, hence why I suggested using more leverage with a piece of pipe. I keep a 3 foot length of pipe to get extra torque on the check key in my tool box. I've never lost a part since I was an apprentice. If you look up the specs on that off the shelf chuck it'll likely have a warning against using a hammer on it. For the record I'm not telling you not to do. Just telling you why it's considered a bad practice in 99.9% of cases. You clearly aren't swinging all that hard at it.

@@clockworkleather their company manufactures the balancer. Their scroll plate might not be cast iron.

[@clockworkleather]

@@CM-xr9oq they likely just buy those standard lathe chucks and install them. Just like most machine manufacturers. And yes they might not be cast iron internals. Again. I'm not saying she's in the wrong. Just saying why people say not to do it. That's it.

@@clockworkleatherunderstood, I didn’t think of it by this perspective. I’m honestly not sure if it’s cast iron inside but you’d peaked my interest. I’ll lyk, I’ll talk to our engineers😉

[@justinkorpela7955]

Watching your videos puts a big smile on my face your so talented 😊

[@dummy3333]

That's one thick, long, stiff shaft, and you're very talented at handling it. (Sorry, I'm sure you get these daily. :) )

[@controldatablock6687]

Don't the cast iron yokes play a role in the balancing/imbalancing the the shaft? For every different yoke used with say the same shaft, won't you get different readings every time? Thus when the customer puts their yokes in, the balance may be different ?

[@darklydemons4497]

Yokes? Do you mean the flanges ? The yokes are welded on and some are aluminum based, not many (with aluminum) is cast iron (not saying it’s not common) ,, anyways. It’s tapped down for run out, then welded, then assembly (which tap down and assembly/snaprings/dropped pins/crushed thrust washers will greatly effect the run out) then going over to balance we have fixtures and flanges that would be in your car or truck and the driveshaft slips in. So the part I attach in this is just what’s in your car. It’s like a dummy. Anyways, changing the flanges/fixtures will not effect run out. Also while balancing you want to check run out and 0 it out (I didn’t show in video cus I try to get it to 0 before welding). Hope that answered your question?

Awsome work. All i get is dudes that look haggard to work on my driveshaft. Lol.

[@madislandguy]

Judging by the blood all over the hanging plastic sheet, I would guess that the previous employee didn't tighten down those 2 chucks enough.

[@darklydemons4497]

This made me laugh out loud

[@korn38ktm]

look up what a cheater bar is as everyone else noted, hammers hammer and that can not be good, like how you should not use an impact on all fasteners

[@darklydemons4497]

im gonna use what I’m given by my company. My company isn’t gonna splurge and buy other equipment. And im sure as hell not gonna buy it with my own coin 🤷‍♀️. I wish people would understand this is a manufacturing company that just wants everything done quickest and easiest way and they aren’t gonna spend the extra money on little things when you can use impacts on literally reg bolts. - also these fasteners are replaced often and aren’t included in the sale of the driveshaft itself. Although you can buy them from us separately. - also just talked to our engineers and the whole chuck is hardened steel and confirmed and extra time that THIS WILL NOT MESS UP THE CHUCK. I trust my engineers who made it over anyone.
