Steve Sells Posted December 13, 2019 Share Posted December 13, 2019 it looks like you used a heavy board for the air flap Link to comment Share on other sites More sharing options...
natkova Posted December 13, 2019 Author Share Posted December 13, 2019 It is 5 mm thick about quarter of inch , eood.is not to heavy, its thick but not so heavy for flaps I think. Would twist board make me a problem for gasket/valve? Board Is twisted like this ( and flaps come like this on top I( would air leak underneath I do not know I think it wont that much , but i am not sure.

ThomasPowers Posted December 13, 2019 Share Posted December 13, 2019 You want as good of a seal as you can get. I used T6 Aluminum sheet metal for mine and installed a layer of wool felt around the opening to make the gasket. Two reasons for this: If it is the valve to the outside---the intake, then you lose efficiency and after a couple of hundred thousand pumps you may regret any losses! The second is that if it is the inside valve then any leaking can pull hot gasses of small bits of burning fuel into the bellows (unless you have a check valve on the output).

natkova Posted December 13, 2019 Author Share Posted December 13, 2019 I think I need to but somekind of frame that is level as compered to the flaps, now it is not leveled I used to skip that part, I would take picture on sunday and see what can be done, so I dont need to rush with covering I gor these two hides for 30 dollars 60 convertibilr mark, wich is used in Bosnia and Herzegovina. To be honest I ignored and I guesed that flaps would cover all of board but board is twistes. Link to comment Share on other sites More sharing options...
natkova Posted December 15, 2019 Author Share Posted December 15, 2019 I made ribs today, I tried old fashioned way, but as iam a litle bit lazy and wanted to save good piece of lumber and lot's of time I used board instead of lumber pieces that are glued and niled together. Here because midle board eas splited a litle bit I disnt wanted to risk it spliting even more , so I used one small blocks on two siedes under midle board nailed them to baord and drilled them, than I punched those rods in that blocks instead of middle board as you can see Link to comment Share on other sites More sharing options...

I checked today i have leakage on flaps, i wont put leather in it, problem is because board is twisted, flaps dont sit flat on it, i think i would need to somehow glue some board on this board which have badder flatter shape. This create place where small bit's of air can leak, i don't want to put leather and see disappointment. Middle board shape is better, but i don't like how those flaps are hinged i think i need to work on them again. In previous setup, there were only some kind of leather strips without even using boards. Guy who made those bellows used leather an some xxxx metal striping to hold that leather. Iam thinking to build valves like this guy did . Link to comment Share on other sites More sharing options...
grimcat27 Posted January 3, 2020 Share Posted January 3, 2020 Just cut the back off of a leather couch. That way its free. Link to comment Share on other sites More sharing options...
natkova Posted January 4, 2020 Author Share Posted January 4, 2020 I redo valves, I used tehnique that is used in fireplecebellows just put one piece of leather over that would qct as gasket. Why ?Because board is not flat, so flaps cant sit on it properly On 1/3/2020 at 3:55 PM, grimcat27 said: Just cut the back off of a leather couch. That way its free. I have hide but.I.hesistate to attach it on bellows, I had bad.expirience with bellows before, I check everything just to.make sure, and I noticed that.mine 8mm (millimeters) staples sre too short to hold cowhide, I think.I.need.something long as 1/2 inch.

ThomasPowers Posted January 6, 2020 Share Posted January 6, 2020 I prefer to staple and then put a thin strip of wood over the staples and screw that into the bellows board. Link to comment Share on other sites More sharing options...
natkova Posted January 6, 2020 Author Share Posted January 6, 2020 Thomas I have issue with board it is not.so.flat, I cant find flap that would sit flat on it. I can make another bottom board it is not hard, but I dont want , I want to keep this board as lon aa I can, I want to restaurate it, use old parts as more as I can.

I had some shelving that was badly warped and that's what I did and it worked well, took several weeks sprinkling water on them to flatten them.
