There's not much apart from replacement to fix bad pitting in rods. You could try some low-temperature silver solder in the worst pits, then file the solder smooth with a flat file, and finish off with emery cloth tape. OzDozer, Feb 24, 2012

What is the best way to repair a worn shaft?
Restoring dimensions in a worn shaft is an easier task. Although overlaying with fused powder or copper alloys can be done with an oxyacetylene flame, without melting the shaft material, the process still softens the steel. Plasma thermal spray is the preferred method, because the shaft material is heated minimally.
Can epoxy fix pitting in rods and shafts?
However, the cost of these epoxies generally makes Cat parts look like Wal-Mart specials. The problem with trying to fix pitting in rods and shafts is that you need to prepare the surface in the pitted area so that the epoxy can bond to it satisfactorily. This is often impractical, because the pitting usually comprises lots of small holes.

Is spray welding strong?
High-Velocity Oxyfuel Spray Welding Gas achieves supersonic speeds while at the same time powder is injected into the flame. The process provides dense thermal spray coatings with less than 1% porosity. The result has high bond strength and fine as-sprayed surface finishes. Oxide levels are also low.
What is spray weld?
Spray welding is a term used to classify several welding procedures in the form of thermal spraying. It is an industrial activity that involves atomizing and spraying a powder or wire onto a metal surface at a high velocity with compressed gas.
Can splines be repaired?
When your splined shaft suffers damage or you notice wear and tear one option is to simply replace it with another. Alternatively, a salvaging operation can be resorted to, to save the part. Note, however, a repaired part is unlikely to preface the same strength and confidence as one that is new.
Can you repair axle splines?
One of the best features of Metalink™ polymers is their incredible compression strength. This allows repairs of spline shafts and keyways. Stripped spline shafts can be returned to service using Machinable Repair™ Compound by following this guideline.
What is a driveshaft spline?
Splines are ridges or teeth on a drive shaft that matches with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.
Why is a shaft worn out?
Shaft Wear and Damage In the mining industry, shafts can become worn or damaged due to vibration, friction and abrasive media.

What is a shaft sleeve?
Shaft sleeves are cylindrical metal tubes designed to protect pump shafts from erosion, corrosion, and wear at critical points, such as at the stuffing box.
Why does my car shaft leak?
While a careless installation or seal misapplication can be the cause of a leak, in many cases the problem is caused by a shaft that is worn because the seal has become a “grinding wheel” that cuts a groove in the shaft.
What is a repair sleeve?
What, exactly, is a repair sleeve? A standard repair sleeve is drawn from a specialized stainless steel alloy. The outer diameter of the sleeve is then finished to provide a high-quality sealing surface. The resulting sleeve finish, texture, and roughness are optimized for use with elastomeric radial lip shaft seals. In many cases, the repair sleeve actually creates a seal running surface that is often superior to that of the original shaft (Fig. 1). A typical thin-walled repair sleeve adds 0.022 in. to the nominal shaft diameter, which means the original shaft seal size can still be used. This sleeve eliminates the extra inventory and possible problems that could arise if a larger ID seal was required.
What happens when a radial lip seal is grooved?
If the seal surface on the shaft becomes grooved, a radial lip seal cannot effectively keep lubricant in and contaminants out.
Can you install two closely spaced shaft seals?
In certain applications, it may be necessary or desirable to install two closely spaced shaft seals. To accommodate this application, the outer repair sleeve’s flange can be removed, permitting the inner seal to slide over the outer sleeve and into position on the inner sleeve.
What happens if a shaft is broken in two pieces?
If the shaft is broken in two or more pieces because of fatigue cracking across most of the section, not much can be done to restore it to a useful part, except possibly in exceptional cases by special means (see example in a later paragraph). But before you throw a broken shaft in the scrap bin, investigate the failure.
What is a shaft made of?
Shafts commonly are made of hard steel. Welding procedures can affect repairs in many ways. High-alloy steel is prone to cracking when welded, unless special procedures, such as preheating, are put in place.
Why are shafts important?
Shafts are important, highly stressed mechanical elements used to transmit rotary motion from a driver unit to a driven part. Like any other component, a shaft can fail by one of a series of failure modes.

One of my putter shafts has some pitting on it, and I want to get it the heck off! How should I go about doing this???
Feedback
I would just replace it with a new shaft. Most .370 iron shafts will fit a putter, depending on how the hosel is configured. A slight amount of heat until the epoxy loosens and you pull the old shaft and reshaft with a new iron shaft. If you need a special, bent shaft there should be some available through MALTBY or GOLFWORKS. Hope this helps.

You might want to understand where the rust is starting from - from the outside or the inside.
