Bellows depend a lot on how they are made and set up. I built a double lunged set I could pump to welding heat with my pinkie. Another smith I knew used on at a "historical site" where it was set up by someone who didn't know squat about them---he messed up his shoulder from having to HAUL down on the chain using is weight to get it to budge.

Mine used heavy tarpaulin canvas I got for a couple of bucks as scrap from a company that made wind wings for drilling rigs in OKC.

For a nozzle---look out for one of the '50's/'60's kitchen table legs that were tapered steel pipe---cut both ends to get the right length and right nozzle size.

If you were a good scrounger you should be able to make a set for under a dollar...(cost of nails I bought at the fleamarket for a bellows I made for my Y1K set up...)

How on earth do you view the pictures on an iPad? all I get is "Page not found" and no one has replied tyo my "contact us' messages.

this is an international site, I dont know what part of the world you are in but the admins may be in a different time zone
