Hi Frank. Where did you get your gaiters?
I made them myself from the recycled waterproof lining from an old wax jacket, two BA Club Baggage Tag Straps (I'm a bit of a magpie

) and some velcro (non adhesive type as the glue messes up the sewing machine).
The lower ones are based on a set I bought from DaveW and the upper ones I developed on the same wrap around principle.
The Smooth Waterproof surface inside make it easy to clean off any old grease that has oozed out.
If you fancy having a go I could email my drawings (send me a PM with your email address if you do)
