Well I picked up this little brush along with an OS mug. Pulled out the knot, sanded out the mold lines and widened it to fit a bigger knot. I'll add some filler to give it a bit of weight, as it's quite light.
It's pressure fit set right now at 52mm, right were there is a little shelf for it. I'll try it out and adjust as needed, but have a feeling it will stay at this loft.
Old knot came out fine, sanded up fine, I still have to polish it up.
The knot came from Larry at Whipped Dog, it's a 24mm Silvertip, it's soft and appears to have nice density and flowthru (based on a test lather) and I'm very happy with the bloom, the service was great, price was fantastic and Larry was amazing to deal with.
Overall, I am happy how it is turning out. Once I get the knot epoxyed, I'll polish the handle up and put it to use.
