I have a spare rear brake drum for a 2 speeder if anyone is interested. I had 2 made for a recent project I was working on and this one is now surplus to requirements. The drum is turned from the solid and is drilled to fit onto the 2 speeder rear hub and also drilled to fit a sprocket (not included you’ll have to supply that yourself!!). Note a small amount of finishing will be required – 3 of the 6 holes will need tapped to bolt it to the rear hub – the other 3 holes are for locating pegs – also the drum is bare metal and will require some sort of finish to be applied, i.e. paint!
These are a great job as when the sprocket wears out you just unbolt it and fit a new one. Cost is £170 to include postage to mainland UK (what it cost me). Tried to upload a couple of photos but the file was too large!?
If you pm me I’m sure I could email photos.
