I used to some breaker points from time to time. It never was very big business here, most rentals just send the dull bits out over and over! I had a few good customers who would send me a few hundred chisles a year to repoint, but they are all out of business now. For the last few years when I have aproached any contractors about tool dressing they have expressed a preference for simply replacing dull bits! I have worked on a few of the bigger ones too, up to 5". Those big points are a huge pain, just for the weight. These big monsters come in the shop so seldom as to not be worth the trouble. I have to locate a die I haven't used in 8 months and rearrange the whole shop to get the crane in....= barely worth the hassle.(The money on those is pretty good, but I see such bits so rarely ) Tool dressing is really good work, I would like to do more, there just isn't any demand around here. Is there any way to scrape up more of this type of work? Ive been through foundries, boiler companies, paving contractors and rental companies. The local utilities seemed promising but have a contract with someone else that has him working at about 20% of my cost!( $1 per point!) A few things I haven't seen mentioned is those bits that aren't worth sharpening. I did work once for a boiler company. Their previous experience with a tool smith was with someone I happen to know and trust did a first rate job for them. They complained quite a lot about his bits breaking and being substandard ect. I knew better but took the job anyway, about 400 chisles 5/8&78 size. About 120+ were so badly cracked and stressed that i clipped and clipped and could not find sound material in them. These bits i brought to the customer and explained that they were unserviceable. the customer would not accept that this was not my fault or that of the other smith. I should mention that many of these bits were bent past 20 deg, and almost all were mushroomed quite badly. I have no idea what was done to these bits in their service life but by the time they came to me they were pretty much done. That customer was one of only two who I ever found truly angry with the service I rendered. Frustrating since there really wasn't much I could do.
