I thought this might be an interesting thread. Perhaps to exchange ideas, perhaps parts, comments.
On my list is:
1. Refurbishing a Unique Arts Rock Island diesel. Largely a matter of a good cleaning, going through the electrical system, some lubing. Hasn't run yet since purchasing it. Have to find appropriate set of horns.
2. Scratch building a steam loco body to fit onto a spare Hornby clockwork frame. Documenting how I did it for a future post.
3. Fitting three LEDS into Marx Wm Crooks, an 0-4-0 and a MPC SW1. Need to fabricate mounts.
4. Rivet trucks onto four prewar Lionel Baby Ruth boxcars. Repaint one roof.
Whats on your workbench?
