Oops, looks like a computer hiccup posted this twice. Doesn’t seem to be any way to delete it though…
I had what I thought was a really good idea, but it didn’t pan out at all. I’m currently making foundations for the bents on a trestle, casting them in place using forms made of foamcore. Until now, I’ve just been spooning a mix of mortar and vinyl patcher into the forms, but it’s messy. So I bought some pvc pipes, a brass nipple and a short piece of thin hose and built myself kind of a mortar injector. Basically like a really big hypodermic needle. Figured I could just put the end of the tube into the form and pump it full.
Well, unfortunately it doesn’t work at all. Trying to push the mortar through the tube, it just packs down and doesn’t move, no matter how thin I mix it.
