A week ago I posted on the WTB a request to buy some old brushes that need to be restored. I have received two so far with three more on the way. After reading the posts here on restoring I have been coming along fairly well. In the picture below is an Ever Ready H40 and a Made Rite(?) 3 that I have de-knotted and I'm in the process of smoothing out the holes for new knots. I plan on a Black Badger for the Ever Ready and probably an XH Finest for the Made Rite 3. Both are 22 mm. For knot removal, I used three different sized drill bits and got as much out as possible. On my first handle, the Ever Ready, I did over drill the holes into the abyss below but still have enough left to remake a platform for the new knot. I am smoothing out the sides and bottom of the hole with a Dremel grinding bit attached to a small Bosch variable speed hand drill. Still more to go and I may try redoing the lettering on the Made Rite 3.Thanks to all who have posted good information and instruction for brush restoration.
