Si https://www.google.com/url?sa=t&rct=...68911936,d.cGU I get up at 5:30 and decide I gotta try this thing. Now I've had my coffee and will bring my '92 up to the shop because it has a good sized vice on the tail. I have always been inspired by this poem we had to read in high school. I will leave it for you as I go make my first attempt. I want to get everything under the truck up to par before I deck it over with my homemade composite bed wood. Then on July 30th starts my annual week at the Puget Sound Antique Tractor and Machinery meet up at Lyndon, Wa. and I want to have this thing done. Here is your morning poetry read. :

 

Great inspiration, that's going on a wall in my shop. Good luck with your project!

 

Some projects are like marriage, you got to do it to find out why everyone tells you not to...!
Good luck

 

Well it seems to be a success! I pulled the dents out cold while pinching the wide section in my vice, 'Arctic style'. This pulled the whole thing straight to within about .10" or so. After that I did some heat here and there on the high spots and cooled them with a blast of oxygen. This does work in small increments. Then I layed it in my chocks across the truck's bed and made a long hardwood wedge. Using 1/2" nuts as spacers (each with 4 wraps of electrical tape). I made a pencil mark on the wedge at each end and called it zero/ Now I slid the wedge in the center and found the high spot. I heated it there, took 3 or 4 attempts, and now the shaft reads zero in the middle all the way around. Tonight I will make a quick track for balancing by kerfing some wood rails for a couple of new 20" planer knives. Placing them at each end I think it will roll to the heavy part and I can fine tune with the hose clamps. I might weld some steel for weights after all is determined. I don't see any safety issues with my repair. Further details tonight. Thanks all!

 

I commend your efforts. Now take a look at the cross yoke shown in the first picture or so. From the picture, that looks bad enough to set up a low speed vibration. What do you figure the driveshaft will turn, 3500 at the most?

Great job as always Gary. I agree about putting some BB's inside to
balance it.

 

Great job, I love it when something gets done that most people believe can't.

The poem will go on my locker at work as well as in the shop here at the house.

 

I have it on my level and near frictionless planer knife tracks. I have one hose clamp on it and it still stops with the hose clamp's screw at the top. This means it needs another clamp I think. Why does a fluid or BBs balance a driveshaft? I would think they would end up on the heavy or low side and just make it worse> ?? It would be easy to drill another hole at this point if it's a good idea. How much oil (I don't have any BBs ) like a tablespoon or 2 cups or fill it up? And Raystach, I don't get what you are saying. In the first picture I have not done anything to it yet, it is just clamped up, ready for my efforts. If I'm missing something I need to know. This is my first rodeo with straightening any type of shaft, and i know u-joints have a very weird set of rules in how they act.

 

Let me be the first to say this can't be done.

Oh wait... I'm too late.

Nice work!

 

The oil or BB's lay to the unbalanced side and balance it. Don't fill it as then it cant work.
But not enough will not work well either. I would not be afraid to put most of a quart in it.
Or like a cup of BB's I don't think the
sand would work as well as liquid or BB's. Never tried it or oil. I have used the BB's and
they work very well. Try it first with out anything in it. He;l
ya may not need any. You have that shaft lookin pretty. Ya can always ad
something later. This way ya can see how well balancing it from the inside
with something that will shift the weight really works.

A tire can be balanced this way as well Gary. Some tire shops do use
pellets instead of rim weight now with the new style wheels. This is where
I first learned of it in the 80's

 

I love to learn new things. I would wither up and die if I didn't. This website and all of you characters has added a very special dimension to my life and I thank you all.

 

As you also have to us. Me anyway. So add yerself to the characters list
my freind. This whole site has takin on a different meaning to me
sense I started following you around here. You help make it fun.

Excellent. My son is home from welding school and working for me this summer. I'll have to ask if he has any BBs left over from his sixth grade Christmas present, that is if he hasn't put an eye out with them.....
