I got the leather pieces from ebay. If you search for leather at hobbies and crafts section, you'll find plenty of them at very good prices. Try to get a thinner (1-2mm) leather since it is easier to work on.
For this instructable you need:
- a saddle in bad shape
- scrap leather large enough to cover it
- impact adhesives (i.e., Evo-Stick for UK)
- a ballpoint pen
Below are the origins of the saddle and the final looks of it.
There are not many hazards/risks with this job. Watch out what you are cutting with scissors, I know one story involving scissors where a joke ended up with death. Impact adhesives are mostly solvent based, so I advise you to do this job at a well ventilated area, or you may get high (unfortunately :-). But really, don't forget that these adhesives are carcinogenic, really.
Step 1: Strip the saddle from old cover including glue remnants.
Step 2: Measure twice, cut once.
Cut the leather using scissors. I used pinking shears (zig-zag scissors), cuts look way cooler and professional. Zig-zag cutting may also help folding the concave edges, the edges won't crumble too much.
Step 3: Glue the leather and saddle edges.
Please read all the instructions and warnings on the adhesive packaging!.. They are important stuff and there are good reasons why they are there.
Step 4: Stick the leather on the saddle, finish the application.
Impact glue is a wonderful thing. It holds strongly immediately, but also it is very elastic. Great stuff.
Put the plastic pieces and screws back in place (i.e., the rear and nose pieces in my case).
Adore your final product.
One note, though. I found out that my leather was not water-proof. Even worse, it sucks water like a sponge. So, I have to keep it covered with a plastic bag to save it from rain. :-) Maybe someone has an idea on waterproofing it (but without ruining its looks)...
Comments and questions welcome!..
