Either silicone or epoxy (Goop would work too) whatever you use, you only need to use enough to hold the glue plug securly. With epoxy you would probably be fine just gluing the bottom, silicone is a little more flexable so a little more to come up around the sides of the glue plug would be better. In either case you don't want it to squeeze up out of the hole into the hair. The exception would be a wooden handle where you would want to coat the raw wood around the inside of the hole. In that case a thin layer before you set the knot should do it. With your faux ivory, should be no problem. Remember once you have enough glue in there to cover the bottom of the plug it only takes a very small amount to fill the space around the plug and squeeze out. Too little is WAY better than too much.
This might be a really stupid question, but the factory knotted brushes I have now, they look like the base is drowned in glue so it's glued all over the inside of the handle. Am I mistaken? Let's say I get the handle sanded perfectly. It'll be 21mm. I get the 20mm knot that's 20,6mm. I know have .2mm on each side of the base inside the handle. Isn't that supposed to be filled/sealed so water does not pool inside?
If you shake the excess water off after you rinse it, it will dry just fine. If that worries you just keep adding glue until you fill the space, just be careful once the bottom is filed it will not take much.
I'm looking forward to seeing your final product. I have a badger brush that I would like to reknot. It is scratchy with little backbone.
Thanks guys. I have some solid info go proceed on now. I'll post pictures when it's done. It might be soon but it might also be later. I've spent way too much this month already, but hey - why stop???
Okay, knot arrived today. Time for an update to this thread. I decided to once more secure my handle in my bench-drill and see if I could get the remaining glue. Also I needed to lower the hole a bit, as the knot-base was a bit thicker than anticipated. All in all I got a hole that went down a few extra mm and the remaining glue all gone = perfect hole! Sadly a tiny mark on the edge from my last drill-session. Doesn't really show with the knot installed, so I don't want to do anything further in that regard. #05 Shavemac Silvertip 20mm knot / 48mm loft. Looks great, that badger. It's the first time I have a badger of that grade in my hands. It's not as soft as I thought, but perhaps that'll change when I get it wet and start breaking it in. #06 Just as the TV kitchen, I've cheated a bit! It's not glued yet, but just for shows this is what it'll look like when I find my glue in the workshop. I think it looks pretty okay. It's a dirt cheap handle, nothing exotic, but it has a good grip, which is why I decided to use it. #07 Man I can't wait to use it. Finally a decent badger. All I need now is a synthetic and then I'll have settled my SBAD ... I think... maybe... Thanks for all your help in this project. I couldn't have done it without!
Apparently, Loctite Super Glue doesn't work with the handle and the base. Wouldn't adhere. So I'm off to the store tomorrow after some 2 component epoxy.
ahhhh, that went much better. Got the epoxy today, sanded the parts and glued together. Now I need to wait for it to dry.
Still waiting for it to try. I believe it said 6 hours till good but 24 for complete. What bugs me is that I don't even know if it works - I mean, maybe it'll fall right out. Thanks btw
It really turned out great, congratulations! Let us know how you like it after you take it for a spin.
Thanks! I got it installed a few mm below the edge of the whole. That resulted in the bristles being held kinda tight at the base giving it a very "non-bloomy" look. I hope it'll bloom fine with time. Hard to measure precisely but the result ended with ~20@46mm, give or take. 5 hours to go before first test-drive!
Lol counting down haha I remember doing that with my f2 finest knot when it came. Now its my go to brush. My boar silvertip and synthetic get no love. And I gave away my pure badger
After a wash in Williams SS I finally got time to shave. http://theshaveden.com/forums/threads/sos-january-27-2014-february-2-2014.36017/page-4#post-636552
Looks fine, good job. Almost too good. You took a needless risk by working on the hole more than necessary, and the result is the chip that never should have happened. That little bit of glue would have been of no consequence at all in the final reknot. If you needed to seat the knot a couple of mm deeper it is far safer to remove material from the bottom of the knot. The other thing you mentioned is the hair above the glue plug of the knot. It is very firm and difficult to compress (as you now know) so for anyone contemplating a reknot, a smaller knot size will often work better. The other thing to consider is that I see no reason that the knot could not be " bloomed" before it is installed which would give you a better gauge on seating depth and bloom. Just some hopefully constructive comments.
Thanks for the comments. Noted till the next job but I need to mention that the chip occured in my first drill, not this last part to remove the remaining. It went so well at first I got a bit cocky and slacked attention. I had no trouble fitting the tight plug in there. Firm yes, but very easy.
