help to find old post

I think about as year back or so there was a post showing a drawing of the angle of cross cut on a standard firebrick for igloo dome construction.
If I remember right the brick was not cut on a 90 cross cut as normal for cutting your bricks in half. I don't think each brick had both sides angle cut but just one cut to cut the brick in half helped with the way the brick would then need less mortar and kind of fit better. It may have been tappered both sides I cant remember but I think there may have been some thoughts shared on how to precut the bricks a little differently for each course. I am thinking especially for the upper few courses I want to tapper my bricks this time.

A second thing I will throw out as an idea wondering if anyone has thought of something similar to try is making up a special jig to lay the top 3 courses totally seperate from the rest of the dome. Calculate the circumfrance needed from the last course standing on oven before you build this and then mortar it in place as one heavy lid. Last time I did a castable lid and it was ok but may want to try this idea instead. What do people think of this idea....wayne

I often remember posts I read and can't find them again.. the downside to a successful forum!

I think I remember the post you're talking about. Maybe 15*? I seem to think it wasn't that critical (actual angle), and it wasn't too steep of a cut.

thanks folks....I have found it. Post was from "Lars". His idea was to make one cut through full size bricks so the half piece will have one edge at 4 inches wide and the other edge will have a 5 inch width. So one angled cut gives you two pieces but one edge of each piece is not really tappered it is still at the factory 90 degress. A picture would be easier but I hope my explaination is working. I just may try this............wayne
