Norma though I haven't built a frakenweber, I believe Steve has built something similar and recall that he was able to get pretty good results. Since Steve has also built his own WFO brick by brick, I'm sure it will be a piece of cake for you 2. If it doesn't work out for some reason, you can always go the LBE route if you want. I think trying something new that hasn't been "proven" can be fun and rewarding when you get it working. I'm thinking where would we be if we didn't have the drive to experiment and everyone just made Lehmann pizzas?
Norma I think using the original lid to mold the dome is a good idea. You can always eyeball it to see if you'll have enough room in there for the refractory cement, clearance, and pie. I would aim for a minimum of 3" and a max of 5" of ceiling height.
I think your idea of adding kiln pieces to the insulating cement is a good one although i'm not sure exactly how to go about it.
Another idea is to cut down firebrick, stack in a circular shape, and cement them together from the outside. You can then pour a flat circular dome piece to stack on top.
I'm sure there are a number of ways you can proceed with your project. I'm sure you and Steve can build something that will make great pizza. Good luck, Norma.
This is the pizza oven Steve built at Reply 2 http://www.pizzamaking.com/forum/index.php/topic,10057.msg88734.html#msg88734
but he added, I think, refractory cement and perlite to his pizza oven. I don’t think Steve’s oven mod can get to the high temperatures I would like to try and achieve. His grill oven mod does make great pizzas though. He takes his oven mod different places to make pizzas. This weekend he has a pizza making job in another state with his grill mod. I am looking forward to his results.
I know Steve is very handy, but don’t know how easy this mod will be. I think it is going to take some thought and work to try and make it bake okay.
Thanks for telling me that you think the minimum of 3" and max of 5" of ceiling height would be good.
I did contact a kiln person that has classes and makes many things to hear what he might think. He hasn’t gotten back to me yet.
Thanks also for your other idea of using cut down firebrick, stacked in a circular shape, and then cememt them together from the outside.
I know you have made all you mods, after experimenting for awhile.
That experimenting thing can take a long while, as you already know. I also like to experiment, but without Steve’s help on this one, don’t think I could try and pull it off. I just don’t have the “handy” experience Steve has. I am also with you if we just stuck to the basic Lehmann dough we wouldn’t have learned what we did so far. I always like to venture into the world of unknown.
These are some articles and pictures about Pizza Hacker’s 22.5" Frankenweber and also other conversions if anyone is interested in trying to build something like a Frankenweber.http://www.bitethis.net/2010/08/underground-market-oakland/http://www.fornobravo.com/forum/f43/forno-clamshell-another-charcoal-grill-conversion-9229.htmlhttp://www.yelp.com/biz_photos/s2yVNwYH40gr-aKbz30gEg?select=abF9Emgog8H5AMDpnMGIighttp://www.sfgate.com/cgi-bin/blogs/inoakland/detail?entry_id=69760http://pizzacommander.blogspot.com/2010/06/pizza-hacker.html
I also have other links, if anyone is interested in looking at them. Maybe after this thread, if might help other members that might want to mod a 22" Weber.
