Why I Oughta...

Last week, my pizza oven build update included how I had purchased a 10" wetsaw and mortared in the first course of the cinder block stand .  On top of that first course of block sits the rest of the stand, but I opted to simply dry-stack them in place.  The height of the oven floor is one of the biggest build considerations and I'm aiming for between 44 and 46 inches in height.  Based on some tests, that's where I'm comfortable and want to aim to hit when I build the stand, add the insulation and place the floor.   The floor is made of medium-duty firebricks that are 2.5" thick.  Set on a thin base of high heat mortar and/or sand.  Call it 1/4".  4" of insulation below that puts me at 6.75" of height.  The hearth has a little bit of flexibility in it - thickness-wise.  But, call it about 4 to 5 inches thick.  That means, I needed to do a little math to figure out how many courses I needed to build.   46 inches minus 6.75 inches = 39.25".  Sub

With excavation started on the site of our backyard wood-fired pizza oven (on our drywell) , I need to move from the theoretical (What could an oven look like?  How high should it be?  What would it need to be made out of?  How many cinder blocks? What layout?) In my recent post on excavation , I ran through some mental math to figure out what size the hole needs to be, what size the slab will be and how wide the block foundation will be once constructed.  I ran through both a 10x8x16 block scenario and an 8x8x16 block scenario.   The 8x8x16 is the traditional block, but I was considering if the extra 2" block in the first (one or two) courses is appropriate to all for the footing of a brick face on the sides of the oven. Off I went to Menards to poke around in the construction block section.  Back in January, I posted the details of how there are L-shaped cinder blocks that help make proper corners and I wondered if I should be using those to make a square pizza oven stand .    I

Earlier this week, I posted my 3-D model using LEGO bricks of my proposed wood-fired pizza oven stand that would be built from a couple different sizes of standard cinder blocks - 16x8x8 and 8x8x8.  In that post (and using the model), I determined that I needed 4.5 blocks deep (from front-to-back) and 4 blocks wide (side-to-side).  That gave me a 74" deep by 64" wide block stand.  Or 6'2" deep and 5'4" wide. But...there's a new development.  At least...new to me, the novice bricklayer.  Turns out, there are 'corner' cinder blocks.   I discovered this fact when I was at Menards looking over the block inventory.  Here's a few photos showing these L-shaped corner-forming cinder blocks  below and how they work together with normal blocks.  These are 12" block compatible. Below is a drawing from Menards that shows the dimensions of these L-shaped corner cinder blocks in 10" width: There are so many variables that I still need to work out

I've been busy getting to know Sketchup - in an attempt to create a true, accurate model of my (hopefully to-be-built-in-2024) backyard wood-fired pizza oven .  But, I also figured out a different, three-dimensional approach that will work (at least for me).  The stand of the oven is built from typical cinder blocks:  16x8x8 (16" long, 8" tall, 8" deep) and half-blocks of 8x8x8 (8" long, 8" tall, 8" deep) that are commonly available from any big-box hardware store.   I was playing around with sketchup one afternoon when I realized that I could build out a model using some common bricks.   I wanted to get a sense for how the stand would come together and also begin to build out a parts-list for the blocks.   I went up to the kids lego bins and quickly figured out how to build this: Part 3001 (2x4 brick)  has 8 studs on top and is the typical rectangle brick that you think of when you think of LEGO bricks.   Using a one-stud for 4" each direction, t
