there is probably no way you can grasp what we did here from the six photos above, but i’ll try to clue you in a bit. the goal was to build an easy to set up, collapsible, reusable, form for building domed masonry wood fired pizza ovens. this one is 6 feet in diameter and 26” high. we have made other forms in the past, but the ‘easy to set up part’ always eluded us. my brother in law, peter moore, of vermont brick ovens decided he finally wanted to ‘do it right’. of course we had no idea what ‘right’ was but eventually we settled on the 24 piece ‘turtle shell concept you see above. in the first photo you can see the handwheel that, once the mortar is set, controls the ‘collapse’ process. the second photo shows the ‘build’ form, to which we screwed the 120 curved laminate piecess that make up the 24, 5 layer ‘shell’ sections. the third photo shows a completed dome from a previous oven. the fourth shows us fitting up the oversize sections to the final 8 rib form. the fifth photo shows the form set up on site last friday. it only took about 20 minutes to shim it and set it up and get it ready for the bricks. the last photo hopefully gives you some idea of the complexity and size of the finished oven .. lots going on here. if you are curious, there are many more photos and descriptions of the process in three posts on my dorset custom furniture blog. i try not to whine too much, but this one was a real challenge, and when it left last thursday, i was glad to see it on its way .. we’ll be going back for the ‘collapse’ ceremony later this week .. all for now .. dan

Interesting project. Nicely done. How did they do it without a form? Work slow and let it be self supporting as the mortar hardened?

Dan,

This is far too complex for my puny brain to comprehend! Your work is amazing.

Nice one Dan.
Might be able to make a boat builder out of you yet. :-)
Does this have to come out of the mouth of the completed oven when collapsed?
Very nice job and great thought process.

Nice work! I built a arched pizza oven that works great but I could see the time saving advantages of this design .

Nicely done Dan. It looks like it is made in small enough pieces to be collapsed and taken out a piece at a time after the mortar is dry, but it seems there must be some magic to the collapse process, so it will be interesting to watch the finale. It does look like the jack in the middle is lowered and maybe the pieces are hinged to fold inwards or something like that. Sorry, I can’t help playing the guessing game.

thank you all for your comments. regarding the removal, the 8 rib pieces that the shells are stacked on are just slipped into notches in the top hub, not hinged, and should be easily removed through the oven door once the hub is lowered with the handwheel .. best. dan
