Hi - does anyone know where I can get a set of the "cups" for forming brush knots. And... does anyone know the name of such cups? Or the terminology of brush making so I can at least search online?
The cups they use after weighing the hair look pretty standard. Just something to hold and keep the hair oriented correctly. Then at around 50 seconds they move it into a form and tamp it down, I suppose, to get the shape of the knot before tying it off with butchers twine. In the second video they tie the base off with more twine before being glued into the handle. I don't think your going to be able to buy these tools anywhere, and you'll likely have to make a couple of forms out of wood or something.
Contact Mark at Progress/Vulfix/Simpson. I bet he can help you or put you in touch with someone who has been making knots for a half century or so.
But why would a brush maker want to help me do something that takes some of their business? Anyway do you You have an email for him? Sent from my iPhone using Tapatalk
It's unlikely you present a great threat to Vulfix or Simpson. But Mark is also very dedicated to the traditional brush making craft and would almost certainly encourage and help you in anyway he can. Shaving brushes are still really a niche item and there is lots of room to grow. If you interest someone in shaving brushes then someday they will almost certainly buy more than one or try brushes from a variety of companies. Remember this picture?
Go on alibaba they will sell anything to anyone lol. Check it out I’m sure there called something else though.
I thought I heard a reference to them as "cannons". I don't where I heard it but I'm sure it was a shaving site.
I saw this too they are actually using 20mm cannon shells aka bullet shells. If you can get your hands on them and 20mm is your goal that's great. Here in Canada we're not allowed to buy stuff like that. But I did read that some of these guys are making molds with PVC piping and copper which is actually great because there is many different sizes to choose from. If your good with a blow torch and a Dremel bit I would assume you can even expand the copper further. I'm not good at this so I wouldn't even attempt. I found a link that may help. Didn't know this was such a difficult task to find a 28 or 30mm cup. http://www.instructables.com/id/How-to-make-a-shaving-brush/ Hope this helps anything I can do to encourage a new business
I think you could make a forming block out of almost any piping. You just have to be careful about the actual size. For example 1" PVC pipe that I just looked up on H-D's website has an inside diameter of 0.878" which is 22.3mm. That's not a bad size for a knot. The next size up would be to buy a 1" PVC coupling which measures 1.125" or 28.575mm. If you intend to turn your own handles then you can make a knot in any odd size. If you had access to a UK hardware store like B&Q you might have access to a better range of mm sizes, just keep in mind that nominal diameters and actual diameters are typically a little different. I'd turn down a piece of wood to make a tight fitting plug with a convex face to match the brush shape I wanted (bulb, fan or flat top) and glue it in place inside the pipe.
Or, you could have a machinist make it out of brass, any size you like, and Teflon coat the inside. I would do a 2 or three piece design.
I am finally revving myself up to actually make knots... I am going to get the forming tools 3D printed. Watch this space.
You are correct. The traditional name for the knot shapers is 'cannon.' The old texts don't explain why it is called that, but it is most likely because the molds were shaped like toy cannons and were made of brass. Edit: I don't remember if it was from a book, most likely "A brushmaker and his craft," or from a post by Gary Young (Simpson's family member and descendant). Gary was a wealth of information, and also shared other brushmaking techniques, such as "collaring," which gives a two-band brush a distinctive appearance.
The other tool needed is a board with nails driven into and through it. (AKA "bed of nails.") Once the knot is tied and the base trimmed, the knot is pushed into the spikes. Then glued together. This ensures optimal glue penetration. I would disregard that instructable above from the 2018 post. It's very wrong on everything. Practice with paintbrush hair before badger. Look for "china white bristle." This is the best grade of hair for boar knots. Best hair for paintbrushes too, come to that. Edit: you'll want to use strong but thin cord for knot tying. Carpet thread is probably the best choice, but Tiger thread might be a good alternative. Simpson's uses what looks like butcher twine. ShaveMac uses blue twine.
