I have a nice BROWN &c FLATHER SHEFFIELD beech brace reinforced with inlaid brass plates, containing a strong bit spring, which I occasionally use with centre bits etc. There is some wiggle between the rosewood breast pad and the body, probably the result of a missing washer, perhaps leather. Both the breast pad and the body end grain are protected with brass plates, and between the two is a tapered washer. The head wiggles due to a gap in that assembly. The gap is a scant 1/8in. I could make a leather washer to fit there, but I was thinking that a lignum vitae washer might be a better choice. Comments or suggestions appreciated. Don |

Hey Don How’s about a photo? I’ve never seen a wooden washer on a brace (at least I didn’t recognize it as a washer). I suppose you are thinking of lignum v. Because of it’s self lubricating properties? A leather washer would have a bit of give which might be useful in this situation with seasonal movement. Cheers from Waterloo Claudio |

Thanks. Looks good! I don't have a washer cutter, but should be able to do it with dividers, if i go with leather.

Probably most people already know, but it's important to use vegetable-tanned leather, rather than chrome-tanned. The later leeches out acid that destroys tool steels. Most leather used for clothing or upholstery is chrome tanned, and not suitable for sheaths, holsters, or anything that comes into prolonged contact with steel. -- Claudio On Tue., Oct. 12, 2021, 7:23 p.m. Matthew Groves, |

Claudio: However, at only about 3/32in in thickness, and situated between end grain body & end grain cap, I don't imagine an LV washer would have moved enough to disturb anything, regardless of it's grain orientation. I've taken Kirk up on his generous offer, as a leather washer seems most appropriate. I would have tried Lignum Vitae, but it seems less likely to have been used by the makers. Else, where would it be? I apparently neglected to research this brace when I acquired it in Ottawa years ago. I recall it was a busy summer, and I've been busy in the Galoot-time decade since. Today I found some info on the makers on gracesguide.co.uk Brown and Flather were neighbours during 1841. It appears the brace was made between 1817 when Brown went into business, and 1850 when the Brown and Flather partnership expired "by effluxion of time". Really! That's what it says. Henry Brown patented an anti-friction brace at some time before 1849, and Flather advertised himself as making it after dissolution of the partnership. I'm unable to say just now with certainty whether my brace implements that patent.

Hey finally got my email back!! I hope hahhaha Not traditional But several times in my life I have made a home made thrust bearing. Round up some tiny bearing balls. (cut open a little ball bearing with a cutoff wheel) Take a normal thickish steel washer that fits the application, and drill some holes for the balls. 5 is usually enough. It'll work like greased lightning yours scott -- ******************************* Scott Grandstaff Box 409 Happy Camp, Ca 96039 scottg@s... http://www.snowcrest.net/kitty/sgrandstaff/ http://www.snowcrest.net/kitty/hpages/index.html |
