An interesting newsletter article.

Nice write up. I do take exception to the statement that "detailed drawings of the wood parts were never made." We have in fact procured several drawings of specific wood parts that go into the assemblies. The most interesting thing on these drawings is the dimensioning, we have seen wood parts dimensioned to the 1/64th, 1/32nd is more common. Here is a clip of a header piece that goes over the front doors.

These dimensions are targets, I guess, as there are no tolerances specified. In practice expect the builder focused more on the assembly dimensions rather than the piece parts.

Excellent Jon, thanks for the feedback. I was hoping for some additional input from the wagon experts.

It was true regarding the 150-A. I have many for the 150-B which was fully documented. The same situation applied to '28-29 Briggs Fordor models and '29 Murray Fordors, although much of what was drawn for 1930 was applicable to '29 versions.

The article is a nice summary but some of the specifics are a little off and not a big deal.

back in da '60's while doing drafting, the rule of thumb was if you dimensioned in fractions, ± 1/64, if in decimal it was ± .010 if not called out on da print.

FWTW, YMMV

I can tell you from experience that when you lay out a part on the wood from a drawing that is spec at 1/64 of an inch you better have a sharp pencil or scribe. My problem it is hard to see a scribe mark with my 65 year old eyes.
