Model T Ford Forum: Forum 2014: Bow length
Top of pagePrevious messageNext messageBottom of page Link to this message  By Del Judd on Monday, August 04, 2014 - 11:27 pm:

I have a 1924 Model T touring car. I am working on the top.

I need to know the length of the bow on the first set of arms. There are two different markings on the bow.
Thanks

Del,

This looks like your 3rd posting so welcome to the forum. The 1923-25 USA tops are basically the same (first 100,000 had straight line cut all the way back to the rear and after that they curved gently down about 2 5/8 inches at the rear (ref page 327 Bruce McCalley, “Model T Ford”) and the rear window changed in late 1925. Note the Canadian tops were introduced earlier in 1920 (some say 1921) but they had approximately 5 different top bow designs with minor differences. (Ref from memory – the Canadian Service bulletins – so not as reliable as looking it up.)).

There are some excellent tech articles that used to be easy to access from the MTFCI site, they were collected by Tony Cimorelli and are still available at:
http://www.cimorelli.com/projects/touring_top_rebuild/index.html

He has great illustrations of installation on his 1923 touring he owned at that time: http://www.cimorelli.com/projects/touring_top_rebuild/index.html

And he has the lengths of the top bows that he used at:
http://www.cimorelli.com/projects/touring_top_rebuild/index.html which is shown below:





Phil Mino has done a great job of documenting the dimensions of the one man top used on the USA 1923-1925 Model T Tourings. See his postings at: http://www.fordfarm.net/25TrgTop.html

(The 1926-27 measurements are at: http://www.mtfca.com/discus/messages/118802/173560.html?1291318078 and they include some relevant information you can use in fitting the bows that overlaps 1918-1927 when the bend is in the metal top irons reinforced with wood.)

Respectfully submitted,

Hap l9l5 cut off
