would you be willing to make and sell just a shaft cut with threads for 12" of travel and if so how much would you charge ? Could it be done with lighter stock such as a nylon round shaft ?
how much _what?_ That spool holds 6km of "100lb test PE braided fishing line" or 1000ft of 440 Paracord. I have about very roughly $200-$300 USD invested for parts and probably 10-20 hours in designing and building it. I will build you one for $1500 USD plus shipping. Or you can just find all those parts on ebay and build it yourself for a lot less LOL. The shafts are 10mm "stainless" shafts. The chain is O4C stainless roller chain, and the sprockets are of course same pitch and fit 10mm shafts. The bearings are called 10mm pillow block bearings. The motor I salvaged from a worn out 12v air pump. I did custom machine some parts so you'd need to do that or have a machinist help you out.
