Has anyone built one of these machines? It looks like a fairly simple setup, small hopper with a plunger to pack the Sandy cement mix into a die of the curb shape.
Never seen any with a plunger, they all vibrate which consolidates the concrete tightly. Pretty tricky to get the right mix to make run good and smooth
My buddy had a professional unit in which the plunger packs the Sandy cement mixture and with the same motion advances the unit. All you do is steer and shovel. Kinda like a kids play-doh press.
Harbor freight made one years ago but no longer carry it.

Just realized why I thought they were all junk. I must have been using incredibly cheap vibration only machines.
