Has anyone ever looked into having rear-wheel hub splines repaired, such as by filling with weld and re-machining the teeth?

I've not seen anyone posting a thread discussing this, so I would assume the answer is 'no'. Of course this could be done, but unless the ST's owner was a machinist with access to appropriate tools, it would likely cost more than purchasing a used wheel and final drive. Rebuilding the final drive involves shimming the gears - not a big deal but again, it requires tools, parts, and some experience.

There was a guy in our BMW club who was a machinist, had his own business, and after he retired was making parts for antique bikes, but, sadly, he passed away a while ago. He had the expertise, knowledge, and a full machine shop at his disposal, but I would think anything short of that would involve paying for the work.
 
You’d have to be one heck of a machinist to pull that off. Of course, anything CAN be done but what are you willing to invest to get it done.

the main "dish" is forged steel; a glowing hot lump of metal dropped into a mold, a huge 'hammer' slams from above with several tons of pressure to shape and harden the thing...
After cooling off the raw part get machined: bores set, machined on a lathe, the splines cut...

I don't thing that anything you'd arc or spray weld on that area will have the same metallurgic rigidity...
And setting up the machine + the hourly rates for the shop will exceed the price of a new set of OEM splines by far...

That's if you can find the parts.
 
There are a few commercial offerings of such a repair in the BMW airhead community. Hansen's BMW in Medford OR was well known for this service. It was a weld/machine in situ operation at that time by an outside vendor (Paul Sturges). IIRC, was about $175 back in the 90's. Nowadays, there is a machined spline available, needs a cut & weld operation.

Need a motivated individual to create the same part for Hondas. Do the ST1100 ring gears fit any other models?
 
There are guys in Pakistan. India. Probably elsewhere....can machine anything..forge anything. Cast....half hour or less. It is all there for the looking on You Tube. Working on the dirt, sandals or bare feet. all the tools imaginable.....well...except torque wrenches.

Larry, what machine are you talking about?
 
It could be done, either weld atop the old spines and cut new grooves or cut off the worn stub and weld on a new one. Getting the right dimensions for the stub, grooves, etc., would be the hard part. Thus, the recommendations of a good metal fab shop.

For the ST community, it doesn't happen enough to really warrant making a new part as there are used ones available for much less than the fab costs. One could get a part number and try to cross-reference it with other Honda bikes too to broaden availability (GW? PC800?).

I have a great deal of respect for these guys - they work magic (well iron and steel) with old (aka primitive) tools, however, I suspect the warranty might not be up to Honda's standards. Seriously, were you marooned in Pakistan it might be an option, but for @Larry Fine in Richmond, VA ebay would be a better option.

Not really that complicated provided the correct machinery is available. It is a pretty straight forward machining job for any competent and properly equipped machinist who has the correct dimensions. Nonetheless doing so would be cost prohibitive for anyone paying standard rates to have it done.
 
Never heard of this on an ST, but did replace my NT700 rear drive complete with one from a NT650...

However, not relevant to the ST so would as others probably indicated, get a decent one from a written off ST or an inexpensive parts bike....

Any other route would be an engineering nightmare with no guarantee on results.
