Come on.....
Who has a set of original bows that can be measured.
The width is dictated by the size of the box..... The height once fitted into the box brackets...... The first bend should be at about 85 degrees so the top section will be partly bowed upwards when fitted to the box.... that should keep the tarp slightly higher in the center so it will not sag with water..... I think the approach by Chris of doing them in two pieces then cutting to proper width has a lot of value..... a simple inside dowel at the overhead joint with decent Mig welding would solve the problem. Are the bows interchangeable between ealry 2B1 and later 2C1 boxes.... as I am interested in the cab 11 box ....... I bow to the experts. Bob

Bows
I don't know if the bows on the #12 cab box, with the fold down sides, are the same size as the #13 cab solid side box. Obviously I don't know the proper box identification numbers. If the two box types share the same bow dimensions then the Oshawa Museum has a set. The #12 cab Ford truck I donated to them had a set of original cargo box bows. Perhaps they could be used as a pattern, or measured for reproductions.

Thank you thank you!!
Gentlemen: Back on focus!!!! Just got off the phone (2hrs) with Joel to try and get the proper answer to his dilemma. Thanks "Boobie" for the" needle in the bum". I have strongly suggested to Joel to get on the phone and call the local regiments, as there are are a couple of 15 CWT'S floating around in the Niagara Peninsula. What I have suggested to him is a template of each bow and cross member, plus photos, and from there, he can take them to his metal shop or a local business and have them fabricated. Hopefully, he will share this info on the forum. The input from all the members has been greatly appreciated and enlightening, so Joel will keep you posted on the out come.
 Robert PS: and no more G'D Horns! R.

TooT TooT.....!!!!
Gord..... you are right the Oshawa group as a cab 12 with the same box as my cab 11....... but is it the same for the cab 13.... all you really need is the radius of the curves and overall dimensions...
Now...Joel.... the aircraft museum in Hamilton had a cab 13 15cwt.... not sure if they sold it.... but it had bows..... not sure if original. I already have a new tarp made by Stew Loy and Co'y and will probably adjust my bows to fit the height of the tarp for a better fit...... or amybe allow for the bows to be adjusted downwards if the tarp shrink over time.... I can check with the CWM in Ottawa but not sure if what they have is original.... Now horn wise Phil Waterman as a discreetly place air horn near the top section of his C60 tall radio box.... which commands a lot of attention when used on the highway....... Bob

TooT to you to - but back to the bows
Hi Bob
Yup added the air horns after one to many little cars tried to become wheel chocks. The regular horn is for the polite Toot the air horns for getting their attention. Now back to the bows, I've been thru my photo collection to see if I could find what a "original" set of bows would look like. I'm not sure there is a single correct design. I've found period photos with the top of the bow flat across form the to side bends, others with a little peak in the middle others with a significant peak in the middle. Then look at the non cargo versions with the bows and canvas added to disguise the special purpose truck as a plain cargo. There also seems to be a lot of difference in do the bows have fore aft bars or boards. Which gets into the whole question of will the truck be parked outside with the tarp on in the rain or snow? Because if the answer is yes the fore aft connections tend cause the canvas to catch and hold the snow and rain. Cheers Phil

Photos....
Phil/Bob: I scanned and emailed a couple of pages from Bill Gregg's books, down to Joel. Given the photos and measurements from the book, Joel should be able to manufacture the bows for his 15CWT. If he's got a talented person in his shop, he shouldn't have a problem. I know he's also trying to get in touch with some local 15CWT owners. Just has a problem getting the owners to return their emails! Cheers.....Robert

I have an original bow off a 2A1 but they're a bit different to the other 15 cwt bows. They are made in two pieces and welded together at the centre.
