Great work!
Thank you both. Darkbulb does have first hand knowledge. I restored one for him as well. Maybe he can post some photos.
The process on restoring a 400 is straight forward but time consuming.
1. Unscrew the collar from the base. I used a strap wrench around the collar and a table top vice with plastic inserts. You could just as easily use two strap wrenches. It will help if you use some painters tape around the brush collar to prevent deep scratches.
2. Remove the old knot. with the collar removed I cut the old bristles and drill a hole through the center of the knot. Then use a screw driver and press down around the knot. I find that the old glue cracks and breaks away.
3. Sand or polish the handle. This is where you will have to decide how far you want to go. To get a mirror finish takes time working from 180 or 220 grit sandpaper all the way to 3000-5000 wet sanding. Then aluminum polish with a soft cloth.
4. Pick a knot. The collar will hold a knot of 24 to 25mm at the plug. Setting the knot is pretty easy and there are several different methods. I used the 2 part epoxy putting to build a shelf for the knot at the correct depth and then set the knot with silicon. The one pictured above was different in that the Omega has a bigger knot. After the knot was removed from the Omega handle, the plastic sleeve taken off. That leaves a knot with a plug of around 25mm but the hair just above the knot is around 27mm. This required the opening in the Rubberset 400 collar to be opened up to accept the knot.
