a round dryfit build
« on: April 24, 2018, 06:03:50 PM »
So my old dryfit with rocwool insulation got infested with mice this winter.  So I had to rip it down and decided to try remaking it using round castable homebrew bricks.  The castable homebrew uses sand:portland cement:fireclay:masons lime (6:1:1:1).  I will make 5 of these bricks to make an oven with an inside diameter of 44".  I will use angle iron for the roof support as in the past.  Will cover with 10:1 perlcrete for insulation that is less inviting than the rocwool.  The pic is the first firebrick.  Each brick is 11.5" high and 4" thick and weighs about 90 pounds.

I'm thinking of redoing the front and vent of my oven with castable -- watching with much interest!

Here is what it looks like with all 5 blocks and a mock-up of the entry, not sure how I plan to do that yet so trying a couple of options.  Tried the inlay on the block that will be the back block, worked out ok.  I cast all the blocks in my basement as it has been too cold up here in CT for outside pouring.

Pete,

I like the name you chose for your oven ;D.

Good luck with it.

That is a super cool project. Can't wait to see it finished.

Here is the base (from the old oven as well).  The top of the base measures 6 ft x 6 ft.  Used 9 log sections with the logs around 12" in diameter.  I used some chainsaw joinery to fit the 4 x 6s into the logs and then a bunch of 2 x 6s jointed into each 4 x 6.  Two sheets of cement board and then about 4.5" of 6:1 perlcrete.

Made some progress this weekend.  Cut and layed the hearth bricks, placed the big firebrick blocks on the hearth, placed the angle iron and layed the roof bricks, and added a perlcrete insulating top.

That’s a monster! Looks great. Reminds me of my first dryfit, but yours raises the bar.

So the perlcrete dried enough for a test run and I thought it needed some insulation on the sides before it would maintain good temps so I did use rocwool around the sides.  I will replace the rocwool with perlcrite as time allows.  Enclosed with paver façade bricks (still need a few more) and fired it up.  It worked pretty well, the increased size required more time and wood but then that size gave me more flexibility cooking.

It's been a while but I found time to finish the front section.  Brick tetris.
