Grinding machine for drum brakes.

[tonyfoale]

Great machine and a solution to a common problem, it certainly beats my method of gluing diamond cloth on sacrificial brake shoes and riding round the block a few times.
Great web site by the way, I will register soon out of interest.

Dan,
I have done similar, and it can remove the glaze and restore some braking but it doesn't do much for an out of true drum.

Very good design & execution. I'd made one change which would be to include a way to use a single diamond dresser to true up the grinding wheel. Otherwise you'll have chatter from the out of round and not concentric wheel.

Love your idea regarding grinding of old motorcycle brake drums. I had occasion a number of years ago to repair a set of drums from Yamaha road racing motorcycle. These four leading brakes were notorious for heat warping and were a real pain in the ass to keep in top shape. I set up a grinder attachment in my lathe to do the actual grinding of the drums. Working slick for the three or four I had to do. I've followed your work on motorcycle chassis development for a number of years and have been very impressed with your ideas and designs. I have a picture of design that you developed for a three wheeled tilting motorcycle. Did you ever build one of these bikes? I have had an interest for a number of years to build such a bike and was impressed with your design for a trike utilizing what I believe was a BMW boxer engine layout.

I always true grinding wheels with a diamond, internal or external. I get no chatter.

I can agree with that. They were large and so they made some sections too minimal to keep the weight down, with the results that you point out.

Unfortunately, that TTW (Tilting Three Wheeler) was one of the very few projects that I started and didn't finish. However, I have over the years been involved in numerous tilting projects as a consultant. One right now actually. I wrote the TTW chapter for the SAE book "Alternative Vehicles in the 21st Century" by R.Q.Riley. That is a very interesting book if you get a chance to read it.

Is this the design that you were thinking of?

Wow that's two surprises. Many thanks again. Not what I expected when I joined the forum and not I was aiming for. However, now you have put me under pressure, I am very competitive and so I find myself thinking what I can do to pull off 3 in a row. I'd better start typing.

Amazon and Paypal are the only 2 of those that I use. If the Amazon card is valid for either the UK or Spanish Amazons then I'll go for that. My email address is in my signature below.

Again many thanks
