Thanks, I planned on making the grate removable after reading several threads but was going to use the 20mm to make it.JKalchik wrote: ↑December 10th, 2018, 5:57 pmOh, WAIT!!!!!!
Make a removable grate, don't make the bottom of the firebox the grate.
A removable grate has a few advantages. You can dump the column into the ash box if you have a run away. You can shake the grate to knock the ash loose. You can pull the grate out if you want to unload the charcoal column. Personally..... I don't see any advantage to a fixed grate. YMMV, though.
I don't pay for the gas work do but have plenty of 16mm round bar.
