RazoRock 400 Knot Removal and Swap.

    I received this RazoRock 400 the other day. I'm not a fan of Synthetic Knots. So, when I ordered the brush, I also ordered a Whipped Dog High Mountain Badger Knot, knowing I would swap the knots.

    Before the operation.

    After 5 minutes in a Vegetable steamer. The hairs separated from the plug inside. No saving the knot. At first, I held it for 5-10 minutes in front of the vent, which gave it a good steam, but it didn't show signs of loosening. So, into the steamer basket it went.
    I will next have to meticulously dremel the glue plug out, and try not to mare the finish. If anyone else has ideas, I am open to suggestions.

    Just wrap the ferrule up in duct tape, just in case, and use the Dremel.

    I will do that, after I give it a good boil, in water. I noticed that when I pulled out the knot, the glue was slightly soft. When the handle fully cooled, the glue was rock hard. Safest method first.

    Who knows, if it gets soft enough, you might be able to pull it out, probably in pieces. If you use the Dremel, it might be better to do it while the knot is hard. You might gum up the bit while the knot is soft.

    Stick it in the freezer, then whack the glue with a small chisel or screwdriver and hammer. The glue might shatter like rock candy and fall out leaving a clean hole.

    Success!!!!!

    Boiling the ferrule in a pan of water, for a few minutes softened it up. It chipped away, and crumbled, when pried with a small
    Flathead Screwdriver. I had to reheat it three times, because it cooled quickly. When I approached the bottom, most of the remaining plug came out. I then just scraped away with the Screwdriver. This was remarkably easy, and I would do this way again, in a heartbeat.

    Glue Plug out. Next will be the Whipped Dog High Mountain Badger Knot being set in Epoxy.

    FYI, this is very soft Aluminum, that they use. If you chiseled on the inside, and set the end on a hard surface, the side touching the hard surface would surely dent. Good thinking though.

    Very nice work. How deep is the ferrule?

    Sorry, I didn't measure it.

    I epoxied the 24 mm Whipped Dog High Mountain Badger inside, and let it cure. There was room to spare, for the knot. The Ferrule looked like it would fit a 26 mm knot.

    Finished.

    Does it have any backbone? Looks over soft.

    It's fluffy, and it holds a lot of lather. Not even close to what my Omega Boars backbones are.

    That's cool,... you should try a badger from Maggard, firm, full, AND soft, I love 'em.


    This is a Maggard, and it's dry in the pic, not bloomed.

    Mine is wet, when the picture was taken. I don't think that made a whole lot of difference. I will say, it is Very tightly packed knot.

    If the ferrule is deep is there not a chance of an air bubble behind your knot or if not completely sealed with epoxy and place for water to accumulate and rot the knot from the back outwards ?

    I set it in good. I also twisted it, and added pressure, to make sure it was seated well. . As I have mentioned, the diameter of the hole was larger than the knot, about 2 mm extra room.
