Pompeii PDF Plans vs. Website plans

[Ken524]

Hello,

I'm studying everything with a fine tooth comb before I begin work on a 42" Pompeii.

I noticed the website and PDF materials lists show dimensions of:
Foundation - 80" x 94"
Block Stand - 72" x 84"

Then on p.13 of the PDF and
http://www.fornobravo.com/pompeii_oven/foundation.html

The recommended dimensions are:
Foundation - 77" x 86"
Block Stand - 69" x 76"

Why are they different? Is this an oversight, slightly different design or am I missing something?

Cordially,
Ken

I think, It's not exact, but 72 and 84 are both divisible by eight. The actual measure of a concrete block is not 8 by 16, but 7.5 by 15.5 I think one may be a mortared dimension, and the other a dry-stack dimension. 4 and a half times 15 and a half is 69.75.

Based on some recent discussion on some of the threads here your other option is to build it slightly big. You can always make a smaller floor and dome and have room left over for insulation. It is a bit trickier when you near the end and realize that you are tight space wise

Thanks for the responses. I like the "build it slightly bigger" approach. Seems like I can design a block layout that will involve less cutting.

I'll try not to make rocket science out of this and keep it simple!
