looks like the same unit as I am using or a knock off of the same unit.
I asked about a replacement cylinder an they quoted a reasonable price + twice the reasonable price for freight
As it is only a cylinder with flanged at both ends I am looking at turning one up when the big lathe gets commissioned .
I was looking at a length of plastic pressure pipe & through bolting the top & bottom together
Some schedule 40 PVC might work too, as long as it wasn't too tall. Or for that matter, with the fitting on the top, It's should be pretty easy to make one.
But I ain't got no time for that, at the moment. Maybe a winter project. But I need to have this replaced within the week. Or so i'm thinking.
Before I started this cam job a little after lunch, I used the hand pump, and it worked as long as I didn't pump it more than twice.
