Re flat leather belting, on the Metalwork forum one of the members was giving away and posting a stash of belting his work was throwing out.
He sent me up some stuff for my lineshaft.
Oxx and Bert from memory but just have a browse.
I have recently bought connectors here in Oz online from a mob down the ‘Gong.
I have a few presses for attaching these and a loan might be possible if you need one as I get up to Brissy a few times a year.
