Hi Brian
Good question about the postman, mine is the same, i guess bubble wrap & lot's of Fragile sign's on it, do not bend etc, maybe a pencil in the belt tray would stop it bending or make it more rigid
As for the price i guess that's up to you really, as you put in all the effort, i have no problem parting with £10 + P&P as this is the only part stopping me running my cat
Btw i forgot to say they look great, fab job Brian
