[Artemisia] Cord Question

[Aghren the Brus]

Leather lacing might hold against the heat. Leather was what was used for 
power transmission in the early days. I am thinking of the flat lacing for 
leatherwork, not bootlaces. Splicing would probably be your weak point. A 
well glued double-taper would be my suggestion on that.

When I was picturing this lathe in my mind, I saw v-belt sheaves with string 
running through them. For leather drive-belting you should use a conveyer 
belt-like smooth pulley. To keep the belt centered it should be slightly 
(smoothly) crowned - like a 1 degree slope from center so the center 
diameter is slightly greater than the edge diameter (imagine a pop can that 
froze and bulged).
Additiionly, v-sheaves create heat. That why v-belts are so hi-tech (to 
resist the heat).

Leather belting will probably glaze and harden with use which might make it 
slip. To counteract this you need a belt dressing. A common leather belt 
dressing in this applicatiion is bees wax-based and is available 
commercially thru industrial supply stores (but a tube would be 27-lifetime 
supply for you). Rubbing the lacing with plain beeswax would work.

Another item that would work (even on v-sheaves) - an o-ringsized to fit. 
Not period, doesn't look period, but it would turn wood.

Good luck,
