oasiscdm found the way to do this "off the grid" so to speak. Look closely at the pics in this post. He has a spacer bar clamped to the IT. The spacer bar is gauged from the floor of the oven. The spacer bar keeps the course level into the arch while the IT maintains the angle of the brick in relation to the anchor point. It is an ingenues technique. It could have been what the Romans did 2000 years ago

. Thanks, Joe, that will make it much easier to avoid catching the droop
. Most of the inner arch is up, course 2 & 3 complete and tied into the arch and course 4 mostly finished and tied in on the left side. It took much longer to cut the tapers on the arch than I thought but it got easier as I went. The inside of the arch doesn't look all that great but I'll clean it up with a grinder once the arch is complete. I know no one will see it once the oven is built but I want to make it look better for my personal satisfaction. The last thing I did before tidying up yesterday was to set the anchor for the 5th course so it will be ready this weekend. Ok, enough of me talking. Pictures tell a better story and I've got a bunch this week so it will take several posts to get them all in. Here is the first set.
. Some touch up work will be necessary on the underside of the arch where it sat on the form. I'll need to tuck point some of the joints and get the grinder after some stray mortar but I kind of expected that. I think I remedied the minor case of the droop I caught last week. Take a look at the photos and let me know if you see any lingering issues. Won't be any more real progress for a couple weeks. I have to go to NC to my nieces wedding next weekend. As always, thanks for following along.
. During the next firing I pulled plenty of coals into then entry to sanitize the area
