You make some great looking brushes. This post is very timely for me. Have not seen your posts before. My youngest Sister asked me earlier this year to make her a shaving brush holder/stand as a gift for her husband. I have finished the stand and over the past week or so was thinking of maybe including a nice custom made brush with it. Had been researching brush knot types and was wondering how the knot is secured into the handle. Never used one myself, I am an rotary electric type of guy:biggrin:, tried razors and lather in my younger years but preferred the triple header electrics. Any way I was wondering if you might know of a tutorial available for make the brushes or perhaps you could provide some detail on your method.
Again those are some great looking brushes and I have scanned through most of the entire thread.
Hi. The knot is secured using 5 minute epoxy. I usually drill the knot hole with a forstner bit a bit smaller than what the final opening will be. For a 24mm brush I drill with 7/8" bit. I go down about 15mm-17mm as most knots sit about that deep in the handle. After the knot hole is drilled I drill a 11/32 hole at the bottom of the knot hole. That is about 15mm deep. I cut some threads with my 3/8 tap in that and mount it in the lathe using a chuck I made with a 3/8 bolt embedded into a piece of ash I turned true on the lathe and shaped into a cone shape to make it easier to shape the handle once mounted. I use tail stock without the point to shape the handle axially and then when I am done with that I remove the tail stock and even out the bottom of the handle and usually dish it out a bit making a very shallow bowl at the bottom. That prevents the brush from sliding on a wet surface, but is not strictly necessary. Once all rough turning is complete I take the handle off the lathe and adjust the knot opening to fit the individual knot I have for it. Then back to the lathe for sanding and polishing. I use progressive sand paper grits up to 1500 with resin, then hit it with plastic polish. With wood I do a similar coat as on pens using CA and sand and polish that as on a pen.
Hope that helps!
