Title: A little rotor resto
Post by: oldschoolace on January 16, 2015, 05:19 PM

Thought i would bung this up as i came up with a nifty way of restoring and polishing round things like hubs, posts or as in this case a rotor  :)

I was trying to find some way of holding the various parts of a rotor while i tidied them up. Sanding by hand can be a pain and its difficult to keep the grain running in a circular motion, especially if you want to try and preserve original machine marks as i did with this rotor.  I have sandwiched things between two large penny washers before now but its not ideal and if they slip they can leave marks on the piece. After a little thought i found the perfect solution, Rubber bungs and door stops!

Both can be found with holes in the middle which you can drop on a bolt, cap with a nut and mount in a hand drill or pillar drill  :daumenhoch:

In this pic i have an orange bung from a chemistry lab, a door stop and a bung from a wine making kit. All have a taper which make them perfect for gripping the work

Not totally finished but pleased with the progress from this:

The bungs can be found in any dimension and really make the job alot easier  :daumenhoch:

Almost forgot, make sure the piece is well seated square on the rubber so it spins true in the drill.   :daumenhoch:

If you need to do small parts, look out for dremel type sanding drums in cheap kits.
These normally use the same principle.

Great result.Nice and shiny but still kept the original machining marks.A rare rotor as well.If you ever feel the need to move it on let me know!  :daumenhoch:

It's the speedwheels spinner Ed was after for a age, quite possibly the only one left out there hence the delicate approach  :)
