What size are the mag post, starter, and bendix screws on a 19-25 Hogshead. What about the threads where you bolt it to your pan?
Thanks in advance, Jacob Mangold

Re: Hogshead thread size

did you really mean 10-32 instead of 3/16-32?
3/16-32 is BSF Fine (Whitworth Thread) and I'm pretty sure that is not called out here, though I don't have access to a drawing
am I about to learn something new this AM?

Re: Hogshead thread size
Well, that dimension source 'as-is" from the Bolt Listing on the Gallery, icon in the upper right of the Forum page. Took it for fact, so will send a note to have this pdf page changed.Scott_Conger wrote: ↑Sat Jul 08, 2023 9:30 amDan

Should have known too, that 3/16" wasn't right, did know it is a very fine thread, and takes care to place it, esp. in the alum hogsheads.

Re: Hogshead thread size

maybe I DID learn something today! (?)
I never knew about that nut/bolt chart so it's a legitimate lesson - and now the question is: is that info from a drawing, or is is a simple error? There's only a couple thou difference between 3/16 and #10 (ignoring the thread form difference)
It's little tidbits like this that I find particularly fascinating, particularly on the rare occasion that such a thoroughly researched subject is found to be in error. If you learn one way or another, I hope you will report your findings. Thanks much for the additional info via your link.

Re: Hogshead thread size
I have that list in its original format, but I like what Adrian did to it. I'll keep his version with the earlier one.

The Bolt Chart on the Forum Gallery was originally a pdf file that was made by one of the T Clubs out west....forgot who posted it originally. But Adrian Whiteman (NZ) did the great work of putting all in the series on the Gallery. He acknowledged some 'errors' are in the listings.....and has asked for help back when.
I intend to send him message on what corrections have observed and will of course add these, the Bendix cover, and the Starter Motor. Thanks all for providing the proper sizings.

Re: Hogshead thread size
Hi guys,
Yes. I put together the 'bolt chart' during that viral lock down using various sources and an original version done earlier.
I am more than happy to make corrections, please send me a PM with the corrections - AND/OR to fill in missing data.
(Thanks Dan - I look forward to the details
)
Kind regards
Adrian Whiteman
