More adjustments

After thinking about this a bit, I realized I should miter the ends. But that still leaves the problem of the roof poles having less tooth to hold on to when they rest on the ends of the "V" section at the top of the walls.

I'm going to use freemason technology to get out of the problem ;) Thanks to Dio for the reminder of this.

Basically, as long as the holes on all lathes are in just the same place, and symmetrical with each other, the lattice will be good. However, using standard measuring equipment to find these holes leaves a lot of room for additive error, and you end up with whole cm up or down at the end.

so I'll just pick an odd number of holes near the projected number the maths says is right, and use "intersecting circles" to get the exact points marked, to the mm.

My index will be an amount I am satisfied with that will give enough "tooth" for the roof poles. Then, I'll carefully measure that point, and its opposite (on the foot of the lathe).

Then I'll get a wooden batten long enough to touch one hole, and when swept up into an arc above the lathe, will make an arc section directly over the mid point of the lathe. I'll drill a hole in the batten, and draw the arc with a pencil. The bottom will be registered IN the hole with a nail, so it will be a clean sweep.

You make two arc sections, above and below, and then do the opposite hole, intersecting the sections.

What you have when you connect the intersection points of these 4 arc sections is a perfect line, perfectly bisecting the two holes.

Draw that line on the lathe, mark the center hole, drill it, and do it again, using that hole as the register.

what you are left with is a series of perfectly equidistant holes, and a pattern for all the rest of the lathes.

Gotta love those masons :) I'l have to secure the pattern lathe VERY well during this, but it will work.

Tomorrow I get the chop saw and commence!!
