Replacing a couple of knots

I've had these brushes for awhile and am finally getting around to replacing the knots.

Attachment 326433
The Ever-ready on the left is getting a Timber Wolf 20mm synthetic and the Made rite is getting a Maggards 20mm SHD badger fan.

Attachment 326432
The Made rite was really simple since it was already really loose. I used a few nickels to set the loft and it just needs to be glued up. I left it a little on the stiff side since I think it will soften up when it breaks in.

Attachment 326431
The Ever-ready went a little sideways. I was cutting the bristles off with some side cutting pliers and it snapped. It should glue back together so I'm not too stressed about it.

Now that I can see how it's put together I've got a couple of questions. It looks like the plug for the knot was poured/formed in the handle. I'd like to get the white part off, but it's pretty firmly attached. Any suggestions?

Thanks in advance.

Also the black part of the handle is completely hollow, so I'm not sure what to set the new knot against. Cut a chunk of wood dowel? I could do a stack of quarters, but I think it would make it too heavy. Again, any suggestions?

All I can say is to clip away at it. The glue and all. You will get down to some little bits after some time and maybe a tiny grinding wheel on a dremmil will take care of the rest.
What is the broken part made of?

Sucks about the Ever-Ready. I'm not qualified to give advice. The Made Rite looks great though.

I was hoping to get the white area off so I could drill it from the backside. Chipping away it is then. At least the new knot is smaller than this one, so I might not need to get rid of all of it.

The broken part is some form of plastic.

Cut a piece of cardboard to fit tightly in the hole, at the proper depth. Then you could glue gun it in to seal it up. Just something to prevent the epoxy from running down when you set the knot.

Or, pour it full of epoxy, to the height you want the base of the badger knot to sit at. I've done this before and it works well. A little extra weight feels nice in the hand. At least to me it does.

I usually use wine bottle cork cut to the desired height.

+1 to that!
I've added 1/2" steel Nuts in the bottom of an empty handle. Toss in a quarter or two to get the right higth, then filler up with epoxy being careful not to over fill. You need to let it sit for a day to be safe but it sure makes for a nice heft in your hand when lathering.

Thanks for all the good ideas, I really appreciate it. I thought about filling with epoxy, but wasn't sure it was the best approach. A little wine cork filler would reduce the amount of epoxy I need. I'll play around with adding weight before I make it permanent.

I would first, glue the handle back together with CA glue, because the CA glue line is invisible. It does not need to be super strong, because once you glue the knot in the handle, it will be glued from inside.

If you try to remove the filler and glue from the broken pieces you risk damaging the edges and you will have gaps or a dirty seam.

Once dry, remove the interior with a large drill bit and drill press, clean up with a Dremel with a cutting bit and small sanding drum, they sand easily. Hold the handle with a wood clamp, wrap the handle with some craft foam or few wraps of duct tape when you drill. Aim for a tightish fit, not too loose, and not too tight. You only need to remove enough to fit the knot.

You do not need to fill the hollow handle, I have used coins, wood dowels, corks, and nothing, just gluing the knot in with clear E6000. I have re-knotted several vintage handles and to date, none have failed. E6000 is inexpensive, easy to apply and clean up. You do not need epoxy, it is messy.

Test fit your knot and wrap your brush, with masking tape just above the glue line to keep the brush and handle clean and easy to wipe off any squeeze out, but most of the glue will go into the handle, if you go slow and slightly twist the knot as you insert in the handle.

Put an even coat on the handle sides with a wood coffee stir stick and a thin coat on the knot only about halfway on the epoxy on the knot.

Once the glue has dried, you can trim any squeeze out with a sharp Exacto knife.

Thanks for the sympathy Paul, but I only paid $4 for this brush so I'm not heavily invested. It's a clean break and should glue back up almost invisible. I like the way it looks so I hope to save it.

I considered gluing it back together first, but it looked easier to work out the old knot with it open. I hadn't thought about making the seam dirty, though...good point.

Got some decisions to make I suppose...

The cleaner it goes back together the more invisible the repair for sure. I have used cold cure for filling handles. It seems very effective. I have been too apprehensive to glue it into a hollow handle. My logic keeps leading back to they did the first time the knot was set. Then I get all worked up in what could go wrong and then just fill it.

Got the knot glued in for the Made Rite and have a couple of shaves with it. I gotta say the SHD badger knot is pretty nice. Not floppy at all and it has a really nice face feel. Makes lather pretty easily as well. It's not going to replace my boar, but will be a nice change of pace. The extra weight I put in the handle gives it a nice feel when I'm making lather.

It looks good
