266812 | Bill Ghio | 2018‑10‑17 | Chisel handle rehab |
Bought a chisel. Too grungy for any normal person to touch, but I thot I saw some potential and it was cheap. Looked like a pervious (ab)user lost the handle so resorted to a steel hammer and went back to work. Later he found the handle and forced it into the now mushroomed socket. The sharp edges on the inner side of the mushroomed top soon dug a groove in the wood till by the time I picked it up the handle wobbled around like a spinning top about to topple over. Because of the goodly amount of rust and really hard grunge covering it I resorted to an unmentionable to remove the "patina”. Found it to be a Buck Bros. 1 1/4 inch chisel w/ about 8 1/2 inches of good steel after grinding it back 1/4” to get past the chipped off corner. It will never win a beauty contest, but is now a serviceable blade. On to the handle. The handle was in good shape other than the conical part that inserts into the socket. Seemed a waste to toss it. Carefully marked its centers and put it into the lathe. Turned the cone into a 1/2” spigot, drilled a piece of hardwood to match, a bit of glue and I had something to work with. Back into the lathe to turn it to fit the freshly cleaned socket and Bob’s your Uncle. Don’t know why I never thot of this before. Bill |

Bill, I believe you’ve come up with an original solution to an old problem! I’ve been reading OLDTOOLS for about two decades; the only similar repair I can recall, and this is VAGUE, drilled the main body of the handle and attached a new piece of wood which was then turned to a taper. Your solution seems better. Your spigot goes to the bottom of the socket. The stress of a hammer blow does not go through the glue joint. (At least, not if my understanding that the spigot includes the tip of the original taper which still rests on the bottom of the socket. Finding mushroomed socket chisels is extremely common IMHE. Some were sold without handles; certain tradesmen beat on the sockets from day one. John Ruth In windy Metuchen, NJ |

Brilliant. Will you re-work the socket? Ed Minch |

I use one of the plumber’s tapered readers to cut the mushrooming off the inside of the socket. Works a charm. Bill Sent from my iPad |

Sounds like another case of necessity being the mother of invention, if I understand what I am reading. If reshaping the mangled taper by shaping and gluing a chunk of donor wood on to restore the lost material and tapering it in the lathe didn’t work, I’d be surprised. I also see no reason why the glue joint has to fail with this approach as long as the old and new wood join line is essentially continuous. Might still need to adjust the taper a bit with soot or similar to fit the socket, but using the tapered reamer ought to reduce the need for it. If done well, Bill’s method might even be invisible. So it is curious why we haven’t heard of this approach before … ? While patenting the idea probably isn’t going to make anyone rich, this might be another way to salvage more of the orphan socket chisels in the world. Charlie |

I see a lot of mashed sockets, but no mangled tapers on the handles. This could be a very uncommon repair. Regards, Steve |

My understanding of socket chisel handles is that you want the internal tapered piece to go *almost* but not quite to the bottom of the socket. Otherwise it will in time work itself loose. My experience bears this out. |

You don't need lathe skills. Being handy with rasp and file are good enough! YMMV, Gary Katsanis Albion New York, USA ---- Kirk Eppler |

Unfortunately, my lathe skills may need brushing up before I attempt this." You'll probably get a better fit by scraping in. without extending the tenon. Cut a sixteenth or an eighth inch or more off the end of the tenon, and whittle back the shoulder of the handle the same distance. Put the handle in the socket, align it to get good straightness, and wiggle the handle around a bit. The dirt from the socket will offset onto the tenon and will, at first, show you where you have to trim back. Later you will have to use a little scrap of carbon paper wrapped around the tenon. Set register marks so that you can put the handle back into the socket in the same orientation each time; you don't want to rotate the handle in the socket as you transfer carbon, since the socket is probably oval or bumpy on the inside---especially if it is a welded socket, not a forged one. 've done this many times; I usually fit by scraping in even if I've made an entirely new handle. Tom Conroy Berkeley |
