[PSUBS-MAILIST] k250 size

[Jon Wallace via Personal_Submersibles]

 All Kittredge subs use 2:1 semi-elliptical.  The length of the straight flange would be the only variation and the plans do not specify that dimension.

 On a 36" ID cylinder, a mating 2:1 semi-elliptical head would be 9" from the inside center of the head along the major axis to the plane at the curvature break at the end of the cylinder. If you're measuring (or if the plans show) a 14" depth of head, that would seem to indicate either that the head is of a non-standard elliptical form, or is torispherical (not elliptical), or is simply manufactured with a substantially longer (5") length of straight flange than is specified by the rules.

I am curious to know which?

Hello, quick question for the k-250 owners/builders. What are the dimensions ( specially the length) of the pressure hull ? Thanks
