Dome assembly Premio 2G110

[DocHop]

Hey,
Dome pieces were much tighter together prior to cap being placed. Upon application of cap for dome all pieces had to be moved outward to permit its placement. I now have about 1/4 to 3/8 inch spaces between all modular oven pieces. Will this be a problem ? I also have a 1/4 inch space between the oven floor and walls.
Thanks,
Peter

I just built a premio 2G 100. I also had space between the interior pieces. It does not appear to be a problem at all. Just make sure you pu on a good thickness of mortar on the outside seams and push it into the joints.

sjdritz,

Thanks for your prompt reply. I'll apply the mortar today and get one step closer to dream pizzas !

Probably the divisions between the castings in manufacture have created this gap and have not been accounted for in the design of the size of the last piece. it shouldn't make much difference, just follow the directions and push plenty of mortar into the cracks from the outside.

David s,
Boy did I push alot of mortar into those cracks...have now covered it up with plastic to set overnight. FB Mortar instructions say curing can start at 24 hours...what is your read on this ?
Thanks,
Peter

Peter,
Follow their instructions. Calcium aluminate cement only requires 24Hrs curing and does not need the extended curing like Portland cement, although waiting longer would not hurt.

Does anyone have advice on curing BEFORE putting on the insulating blankets? I noticed in another thread that Heidi from FB said that they recommend finishing your oven before curing -- but it seems to me that if one of the goals of curing is to force the moisture out of the refractory pieces, wouldn't it make more sense to have them open to the air -- and then add the insulating blankets AFTER it's cured? (I also want that to be the answer so I might cure it more quickly and have pizza sooner!) Thanks.

The glass wool blankets are quite porus so the steam will pass through. I did my first few cures before applying the insulation so as to check the refractory mortar...good to hear you have the dome together !!

Re: Dome assembly Premio 2G110

Oh hey Peter, didn't realize that was you! Yes, you were certainly right - the pieces were REALLY heavy. But they're up there on the hearth now, which is good because last weekend my husband broke his collarbone. No heavy lifting now for several months! (The insulating blankets aren't very heavy, are they?)

I'm hoping to mortar this weekend - when you said it took you 3 hours, were you working by yourself during that time? Should I recruit help?

Re: Dome assembly Premio 2G110

Elise,
Hope your husband heals quickly...they say a good WF pizza will do wonders . I did the mortar work myself, get 2 inch trowel, a spray bottle, bucket and the mortar. Wet the seams on the dome prior to the application as per diagrams on the disc. Remember to place the eyelets so you can secure the insulation later. The insulation is not heavy but it is nasty stuff so use long sleeves, goggles, gloves(rubber textured from HD or Lowes) and a mask. Guess it took me about 3 hrs. I secured the insulation later(4-5 days) with wire secured through the eyelets. Can't wait to see your photos...I just finished the stucco on the durarock I'll send a picture.
Cheers,
Peter

Mind if I ask what may be a dumb question? What are "eyelets"?

Re: Dome assembly Premio 2G110

Rushhour...I used stainless steel screws which had a closed circle at their end...perhaps there is a more precise technical term for them. I placed them at the base of the oven where it meets the insulation in the refractory mortar. Once set, they are a great way to affix wire in an attempt to stabilize the insulating blankets.

Re: Dome assembly Premio 2G110

You are really better to make them from thin wire. The heavier they are the more heat they transfer to the outside. In kiln building, blanket is held in place with very thin high temperature wire for this reason. The wire can be placed in the mortar joins between the bricks.

Re: Dome assembly Premio 2G110

Ohh ok...Thanks
I am doing something similar. Since my Premio is mounted on a steel frame, my plans were to just tack weld very small washers around the base and run thin wire thru

Re: Dome assembly Premio 2G110

Thanks, Peter! My husband had his surgery today and silly gullible friends have offered to help with the mortar - yay! I got the eyelets and will remember your warning about the fiberglass blanket. Hope to have pizza by mid-October (we call that 'winter').
