under the frame i attached 4 2" casters that are slightly recessed. I knew i would wan to be able to move it around when cleaning off the patio, but not have this thing sitting on huge wheels looking unnatural.
Hey Kirks, This was something i was going back and forth on upfront. In my head i knew i could knock out a simple box frame using something like 2x2's or 2x4's. Then though about wrapping it in some fireproof insulation to deal with the heat, etc.. Ultimately I used 1" tube iron, welded together. This was a little out of my wheel house, so i took a hand drawn schematic (i'll upload) to a local welding shop, and traded a case of beer for their work :)
Hey there L2B! What i did was use clamps to hold the hardie in place. Then pre-drilled with high speed titanium metal bits. Then came behind it with the self tapping star screws that you would normally use to attach the hardie to.
I ran into the same issue-- which is ultimately why i built one of my own. I decided to build it a little taller than standard fire pits you would see ad Home Depot. This way kids aren't always pulling the glass out. I also chose not to give it a long shelf on top, so my little ones don't smack their heads into it. Actual Dims: L48" x W26" x H29"
Hey Kevwal, thanks for your comment. I searched around a bit. A struggled between how turnkey, vs piecing it together. ultimately i went with something like this: https://www.amazon.com/American-Fireglass-Stainless-Burner-8-Inch/dp/B0051J1POK/ref=sr_1_5?ie=UTF8&qid=1532011136&sr=8-5&keywords=american%2Bfireglass%2Bh%2Bburner&th=1 The "H" burner blends well and covers a nice area. You can probably get it cheaper, but this has worked well, and hasn't showed signs of rust despite leaving it uncovered in the rain.
Hey Dan -- great question. I played around with different looks until i got the blend i liked. I bought mixes off amazon and walmart. I went for some as the bigger 1/4 inch size mixed with smaller pieces. I also bought some that were reflective, so they would cath the sun during the day, and glow with the fire at night!
