Another Workshop Time Waster: 3000 Gallon Masonry Cistern
awemawson:
Are you planning to build it like a ferro-cement boat hull, using mesh and rendering it, or are you using cut blocks?
At the moment it looks like the Gilded Cage that the singer would be in in a 1960's smokey club :lol:
vtsteam:
It will get horizontal rings of rebar decreasing in spacing toward the bottom to take the hoop stresses and increasing head pressure, then one layer of expanded metal lath and one of chicken wire to shape and hold the cement plaster.
Three layers of sand/cement plaster to finish about 1-1/2". Two issues I see are dealing with the lath sheets conforming to curves in 3D, and the first coat plastering probably working alone. Friends have offered to help, and I may have a mixer helper (though maybe not) but if it's going to come out an unfair leaky mess, I want to be the one responsible for it!
If a 60's style singer shows up, I may leave it as-is for the duration of the act! We find few of them wandering through these woods however.

Steve, I researched ferro-cement boats decades ago, well before the interweb. The received wisdom then was that you need someone on each side for the first coat as the 'outside man' tends to push the pug all the way through, so needs an 'inside man' with a float to push against.
.... maybe times have changed ... :clap:

Andrew, was this the way that the 'Fire barges' were built for the London Blitz?
I certainly recall a couple on the River Tyne.
I'm too busy to look at the 'box' but I caught a glimpse of someone pouring cement overhead onto a skeleton frame covered with a tarpaulin. Maybe it was TF1 from France. I fell asleep!!!

Having seen the intriguing shape of the structure I was wondering how Steve was going to finish off the inside, or more importantly (perhaps :scratch: ) how he was going to enter and exit the shape, so I remain an avid reader..
