Thought I would share a pic of my revamped portable forge cart. Finished it up yesterday and gave her a run today. Could make a few changes but all in all it accomplishes what I wanted. Sure was easy to roll it out of the basement and back in when I was finished. If I had the anvil portable I'd be set.
Cheers,
Ken
P.S. Thanks to all that have posted the 1 part portland cement / 3 parts sand mix. I've been using cat litter which works but is not very durible. Tried the above mix, forged for several hours, cleaned out the forge and it's still in good shape.

Very nice!

Looks nice and practical. For the portable anvil, I use an old gas cylinder dolly to move my stump/anvil around.
