[QUOTE="y4k, post: 210501, member: 4904"] Am thinking of attempting a trommel build now that ive finally got my welder :D was looking through some old posts for ideas on gearing etc which i think ive got sorted out with pushbike cogs and chain but im stuck on actually turning the barrel and where to find a cog big enough to surround it. Obv the size of the barrel will depend on the size of the cog i can find, hope im making sense because im confusing myself as i type it haha but ive seen builds where the chain goes around and over the actual barrel which i imagine would be as easy as cutting the centre out of an existing cog and welding it to the outside of the barrel but the only cogs ive been able to find (motorbike sized) would mean the barrel would be fairly small. Im not looking to build something huge but maybe 20ltr bucket size...any ideas of where i could find a cog that size? [/QUOTE]
