So just what is so revolutionary about remanufacturing shave tools? For years people have been boring the holes oversize and using larger pins, or inserting bushings and using smaller pins. Or hitting it with a hammer until it works (kind of). And these methods have worked. At least for a little while.
However, these methods also cause more problems. Special size pins must be kept with the tools they were made for and are not interchangeable with the rest of the holders. When holes are bored oversize they are often not in proper alignment and therefore must be bored larger, allowing the pins to slip and the holes to wear even faster than before. When bushings are inserted and smaller pins are used, the tool becomes less stable and more susceptible to chatter during heavy cuts. And we all know what hammers can do.
What all of these methods fail to consider is the cause of the problem: that you have a very soft steel body riding upon a hardened steel pin, which inevitably causes wear in the shave tool holder. Our process takes care of this problem, and this is why it is so revolutionary.
Our process greatly reduces wear, increases the stability of the holder, and allows you to use standard size pins!!
The
R & D Shave Tool
Remanufacturing
Process
First, your shave tool holder will be disassembled and evaluated, and a quote will be called or faxed to you as soon as we have determined the extent of the remanufacture necessary. Then the tool is sent to the shop and the remanufacture begins.
Step 1: The disassembled shave tool holder is surface ground to make sure that all parts are square and that our readings from the parts will be true.
Step 2: The locations of the bores on all parts of the holder are charted and recorded.
Step 3: The holes are jig ground oversize. The size of the hole is determined by the amount of wear in the hole and the amount that the holes must be moved in order to make sure that the holes are in line with each other.
Step 4: The parts are sent out to have the holes hard chrome plated smaller than the original dimension. The chrome is harder than the pins, and now the tool will have one hardened surface riding on another, reducing wear. The chrome will also resist damage from chips and filings better than the soft steel that the tool is made out of.
Step 5: Once the shave tool holder is received back with the hard chrome plating, the part is cleaned and set up on the jig grinder. We now refer back to our chart and grind the holes in line and on location to the size proper for that tool.
Step 6: After checking to make sure that the holes are the proper size and alignment, new pins are inserted. Our pins are longer than the standard, and maintain contact with the tool even at the extreme edges of the tool's movement. This makes for a more stable tool, especially on heavier cuts. It also prevents chips and filings from entering the holes, a prime cause of shave tool holder wear and failure.
Step 7: The tool is reassembled and checked again to make sure that the movement is smooth and stable. Then the tool is packed up and shipped back to you.
If necessary, we can also repair the dove-tail tool holding area. All of this will give you a tool that works better, sometimes better than new. And it is vastly more affordable than buying a new tool.
While this process was developed for pin style shave tool holders, we have also done work on both the dove-tail and square block style of tool holders with great success. We also repair the movement on recess tool holders.
