model a frame dimensions & identification
Can anyone tell the total length of a model a frame, Measured from the end of the frame rail to the end of the horns. Also how can you tell the difference between a 28/29 and a 30/31. Any help appreciated.
Thanks, Bob |

Re: model a frame dimensions & identification
The print I have is from WWW.wescottsauto.com
My puter's in terrible shape, I can't post anything or print out anything. However, I have a 103 1/2" wheel base. To which you add 10 I/2 for the horn and 1 5/8" (possibly 1 3/4" The picture isn't clear) for a total of 115 5/8 ". Warning, I have found this Dwg to be off on hole locations. Terry |

Re: model a frame dimensions & identification
The difference between the '28-'29 and '30-'31 is brackets for certain bodies (slant window in '31 comes to mind) and the height for the radiator mounting pads is about 1/4 inch different. The early frames had a solid motor mount as part of the front cross member. Over the years some brackets went from stampings to forgings. The brake system changed . What are you trying to do, a driver or a show car (there is a big difference or a show car but you can work around most of the differences on a driver)?

Re: model a frame dimensions & identification
If generalities are all you are after, that print is fine but if you start looking closely you will see errors/

Re: model a frame dimensions & identification
Here's another frame dimensional diagram that I saved from somewhere - I've hardly looked at it, so can't comment on the accuracy of the shown dimensions.

Re: model a frame dimensions & identification
Is there anyone that has a drawing like the one that Randy in Ca submitted for a 1930/31 frame. I assume these two frame dimensions are the same although very different than 28/29.
Thanks for your time and any help. Cape Codder |

Re: model a frame dimensions & identification
Randy / Cape / Steve - actually, everyone. Randy's drawing is the Wescott drawing (Wescottauto.com). While a lot of us appreciate having it avaialble, it seems to me there are errors and omissions. Ex: the 23-1/4" dimension at the bottom of the rear section doesn't add up. Add the distances between fittings from the same baseline and you get 22-1/8". There's another version of the drawing that has the front cross member in section view that I kind of have a hard spot with, too.
Anyway, I couldn't find a complete dimensional print for my frame (1929) so I started a CAD drawing, but don't want to use my 80+ year old frame as a reference. I'd like to locate bolt holes, sizes, rivets, etc. If anybody knows where it's already been done, that would be great and save me some effort. Otherwise, if anybody be interested in reviewing and giving me input, I'd be happy to post a complete print of the frame on the boards when it's done. Sorry for hijacking the thread. |

Re: model a frame dimensions & identification
Sorry, I didn't notice Brent had already mentioned the errors. I checked out Steve's website, (excellant, BTW) but it would take a lot of parsing through docs, and I'm not convinced I will find what I'm looking for.

Re: model a frame dimensions & identification
Does anyone have the hole locations for replacement frame horns, as to where the front apron mounting bolts should be?
The fender holes I can use a transfer punch. This is for a 29 pickup, and the horns had been replaced, and no holes were drilled.
