The joint I was referring to is not the one at the chamfer line, it is the one below it.  As stated though, if it is going to be banded or otherwise reinforced it is fine.

As for the floor level joint being an issue, it is in mine, I built wall-on-floor, and it does get jammed in there.

The height of the side wall is normally 8-9".

Thanks Tscarborough!   I can understand drawings!  lol

I think I will put the 1" shims underneath,  then the regular sailors and reinforce it with concrete similar to yours and Jon's! I'll start the pitch at the top of the sailor.

Is the ratio different for the concrete to reinforce the sailor than the mortar?

Yes, it should be concrete not mortar.  The difference is the addition of larger aggregate with similar thermal characteristics.  Take your waste from the firebrick cuttings and:

Just to warn you, making that firebrick aggregate took me a awhile.

Oh I can imagine it took while. I'm trying to think of an easier way but doubt there is one... Can u give me a mix for that concrete?   I got 6:1:1:1 sand, Portland cement, fireclay, lime. But do I just add a part of the fire brick to make this a concrete?

Tom, correct me if I'm wrong, but I think it was adding 2 parts grog to that formulation. I did all that parts measuring with a small bucket when mixing.

No, that is right, 2 parts, but reduce the sand by 2 parts.

Thanks again!!!  I'm gonna use the left over normal concrete sand for the concrete and get fine sand for the mortar joints.

Jon I saw you wrapped wire and a piece of rebar in the concrete for your sailors and I haven't seen all of tom's build to know.  Because my sailors are gonna be a little shorter, will concrete be enough or should I put some fence wire and rebar in the concrete mix?

And of course I can't find 'hydrated' lime.  Not at brick stores,  Agri-supply,  tractor supply or lowes... is this usable or the wrong product?

Put that in a bucket, cover with water (do not stir), keep it covered with water and in about three days you will have hydrated lime.

I cut welded wire mesh to strengthen mine. Tom's was a little different. Here is a link to a bunch of pictures Tom posted. I looked at them regularly. His reinforcement is shown on Aug 12.

Does it change the over all mortar/concrete mix or should I add a tiny bit more hydrated lime because of the water?

Put away the scale (never thought I'd type that  :-D) - masonry ratios are  by *volume*.

A shovelful is the standard unit - add water until the texture is right.

No, it will just take a tad less water. And note that as long as you keep it covered with water, it will last forever, and, in fact, get better with age.  3 days is the minimum, in the old days they used to slake the lime for a project in a slaking pit onsite for up to a year before use.

Awesome info.  This works out well.  I can cut bricks (which should be a metaphor for something) all weekend and first of the week actually start mortaring.

When I first started this,  I was trying to get an accurate total cost.   it was a giant pain (for me) to come up with how to transfer tons of rock and sand to yards then shovels.

A better measurement is a standard 5 gallon bucket. To the rim is .77 cubic foot, make a mark 9" from the bottom and you have 1/2 cubic foot, more or less.

I should have asked here!  lol that's perfect.

On the 1" shuns you suggested under the sailors. Should I mortar the sailors to them or let them float?

One more question and I'm ready to cut.   You said to cut the 2 1/4 to 1" and that I would have to cut for height and width.  Can I just cut 1" pieces out of the 9" tall part and only cut once?  Then stagger the joints from side to side?
