Feedscrew Reconditioning

NOTE: If sending in a parts for inspection that has plastic resin on it or in it, then a SDS for the resin MUST accompany the parts.


Standard Rebuilding

In most cases, feedscrews can be rebuilt at a considerable cost savings over replacement. Flights rebuilt with Stellite or Colmonoy Hardfacing normally last longer than a new general purpose feedscrew.

We can rework root diameters, change compression ratios, replace broken drive ends and tip ends, repair I.D. threads, etc. Rebuilt feedscrews can also be hard Chrome plated or Nitrided.

Most standard rebuilding can be estimated over the telephone. Standard rebuilding consists of inspection, grinding down the flight outside diameter, building up with Stellite #12, grinding the root diameter to clean-up, adding the surface treatment, finish grinding, straightening, and polishing. Phone estimates are not firm until inspection has been completed. There is "NO CHARGE" for inspection. You will be contacted with a firm price and no work is ever performed without your approval.
