bent yoke?

[shamefowjze]

i have a yoke that would make a good scaled down version of the st. louis arch. it warped/bent from front to back, the middle(4-5-6) is the part that is too low. is there any way to get a yoke close to straight one it's bent? i think this is the only yoke in the place that hasn't been welded.

Or, you could hobble it like Kathy Bates in Misery.

Best suggestion: Replace the Mo Fo!

Re: bent yoke?

Coors has a good point. I had this problem too on Lane 15 and I used one of those yoke repair kits (the ones when they snap) and it pulled it tight. When the kit's bar is on, it'll act as a straight edge and then you can see how much to torque it up.

Re: bent yoke?

Ed you give such sound advice. I guess you Bruns lovers apply theory somewhat differently than the rest of us.

Alex, what Coors said will work just rig your bracing so that you can heat and adjust at the same time.

If you can configure your bracing with C-clamps attached that would be safer and easier. Make sure you do not apply too much heat in one spot until you get close to being straight.

I'd use 6' - 8" clamps and set your jig so that your c-clamps are on the floor and the clamp handles are standing up. The bigger clamps will give you more leverage when tightening.

Take your time and make sure you pull the bearings out.
Good Luck

Re: bent yoke?

i had a feeling that would be the route to take. i appreciate your replies. guess it's time to make a jig and get a torch set! woohoo [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

Re: bent yoke?

no offence to anyone intended but to me personally the BEST idea came form MAGIC T .... mate replace the thing if once repaired its not perfectly squared up your bound for grief.

Re: bent yoke?

If you are just there to replace parts you might as well work for GM or Ford.

They would rather charge you $200 plus labor for a new starter rather then replace the $13 starter drive in the starter.

I have never been much of a parts changer. If possible, fixing the broken or bent parts can be far more cost effective than buying new. The only variable is time.

I bolt my split cushion planks together with 3/8" althread. Haven't purchesed a plank for years. Can't even tell you how much one goes for.

If I can save money I do it. Although a yoke frame can be tricky; Shams frame wasn't broken, just bent.

Re: bent yoke?

Two things I have found to look at in a non-broken used yoke:
straight run from front to back on each side, and twist.
Sometimes, after straightening or welding a yoke, the front end of it isn't in the same plane as the back, eyeing up the front bearing bores with the back channel. This twist must also be corrected or you will have a bind at the legs.
The downward bend at the 4 or 6 is, of course, caused by table jams under the bin/shuttle. When rebuilding a table assembly, if the bend is very slight (just enough to cause the cup to touch the top of the pin during respot), rather than risk cracking it while straightening, I flip it over. It's identical up-side-down as right-side-up except for the recess in the rear for driving out the rear leg pin.
Also, check the shaft at the 4 or 6 end. It may have a bit of a bend, too.
