re-surfaceing drum
« on: September 07, 2014, 02:35:44 PM »
I'm going to order some new linings from Wayne soon for my bike, and was wondering how people were surface prepping the drums for maximum braking?  Was driving bike this weekend and had to do an "emergency stop" (try at least LOL)  Disaster was avoided but really emphasized my need for better brakes on a bike that goes 45mph.  What grade/grit  sandpaper/finish you think would be appropriate?

I bead blast mine.  It leaves a little tooth, which should help.

When Tom narrowed a rear drum into a front drum, he turned the inside in a lathe to clean it up.

I worked in automotive machine shop for a lot of years.  After we turned drums(or rotors) we used 120 grit sandpaper to take the edge off of the tool marks.  Probably didn't always have too. 

CarryAll,  You should think about giving me a shot at your linings.  I will be posting some pics soon of my set-up for drilling and riveting the linings. You send me your shoes and I will send them back ready-to-go for $40 post-paid.

Here is a pic of a set ready to be put together.

nice work!
The bitterness of poor quality, lingers long after the sweetness of low cost!
