I'm am late updating this thread with the progress. My friend decided to go with a WSP 26mm HMW knot. Setting the knot went very quickly. He has been using the brush and reports that he loves it. Now for some pics. 400-4 with knot set. His 400-4 next to my 400-3 Overall very pleased how the project turned out. Even better to help a friend with such a project.
Now for the next project. I was able to get my hands on a 400-unmarked brush for my next restoration. This is what I started with. Managed to unscrew the brush without to much effort. The knot was fairly easy to remove. Then the real works starts. Starting with 180 and moving up thru 5000 grit sandpaper for several hours of sanding. Finished off with some aluminum polish. End Result Now I need to decide what kind of knot I want to use. I will most likely use a file to enlarge the top opening from 25mm to 26mm and polish again before setting the knot.
I found a rubberset 400, unmarked(I guess). I found it in the wild. plan on adding it to my brush collection. May our may not, need reknotting. Will add more and better photos later.
There were three different model 400 brushes, marked 3, 4 and unmarked. It's my understanding that the markings had to do with the length of the bristles.
Could be. Don't you have a #3 that needs a new knot? I just helped a friend set a knot in a 400 unmarked this morning. I find them very addictive to work on. Here is a pic of Wade's brush we finished up today.
I do...I should measure it. If you find is so addictive to work on them I should just have you work on mine lol (You do a great job btw)
Thank you. It turned out pretty well. During sanding and polishing we discovered a hairline crack just below the bristles. Lucky that it did not go all the way thru and did not affect the finished product. This was the third one I've redone. If I'm lucky enough to find myself a #4, I'll be done.
You are right that it has sort of the shape except for the flutes. I was just thinking of using it, but I think it is a little short. I want to do one from scratch. The Omega handle was my inspiration for my current project.
