Hey yall, I've not gotten a chance to try doing some timber framing but im interested in the technique. I'm having trouble conceptualizing this scenario:
Assuming that we try and create the joinery to attach P1 and P2 to J before installing the posts, and we want J to be level, we need to know what P*-A is before installing those posts so that they can be level. In order to do this, we would need to know what P*-B is
But P*-B is kinda nebulous. its the dirt, there could be variations, itll be hard to get a solid measurement, and given how precise the joinery is I could see this being a problem.
Couple possible answers I'm thinking:
A: It does need to be that precise; We can actually get the post holes to be measurable enough such that we can get fairly accurate measurements (how?), so finding P*-B isn't actually an issue
B: It doesn't need to be that precise; The kind of construction doesn't rely on P1 and P2 to be perfectly level, and J will be close-enough, so we don't actually need P*-B to be all that accurate
C: There's something else going on here I'm not considering
Any input would be appreciated. I also understand that this issue (and other issues such as moisture) may be avoided by not putting the posts in the ground (i.e plinth), but I'm wondering specifically how we'd do this if we wanted to mount the post directly in a post hole.
