1932 bumpers: straight or slightly curved?
In reviewing a post from 10/15/2013 I ran across the following relative to the curvature of the 1932 bumper:
"It bows outward 1/2" in the center between the bolt holes measured on the back of the bumper." I have three bumpers and all three appear to be original. The first is bowed outward by 3/4" between the bolt holes, the second is bowed outward by 1/2" between the bolt holes and the third is straight as an arrow - no bowing. At the center the first bumper bows a total of 5 3/4" outward, the second bows 4" and the third bows 3" outward. How much should an original bumper bow outward at the center? |

Should not bow out at the center at all.

Re: 1932 bumpers: straight or slightly curved?
With respect, I've had far more than my fair share of '32s and their bumpers over the years and in my experience, the only ones that do not have a slight outward bow between the mounting bolt holes are the reproductions. I do not have a copy of the original engineering drawing to support my view that they weren't straight hole to hole, but hanging on my wall is the next best thing, a NOS '32 bumper and it is bowed like that in the center of the first photo.

Re: 1932 bumpers: straight or slightly curved?
I have had the same experience. Repros flat between the holes, originals with a slight arc.

I have written to the Ford museum to see if they have the drawings. If so, I will post what I find.

Re: 1932 bumpers: straight or slightly curved?
From my limited experience the bumpers are under tension when bolted on and that tension causes a slight bow. Is this correct?

Tom,
That happens some of the time with reproduction bumpers given the obvious different grade of steel used in those bumpers, it can introduce the slight curve in those bumpers when used with original brackets, which are obviously stronger than the reproduction bumpers. With original bumpers and brackets, no additional bow is introduced in the bumper, at least in my experience. |

Re: 1932 bumpers: straight or slightly curved?
I made my own 32 bumpers out of stainless steel using the remains of an old original one for a pattern. I did not like the the reproduction ones .

Re: 1932 bumpers: straight or slightly curved?
I wrote the Ford Museum requesting the drawings for the bumper, part B-17757. Only to be advised that, "We do not seem to have ANY Model B or V-8 part drawings OR release info for part numbers between 1754 and 2000. Even if there was no drawing, I would have expected to find releases if the part number was correct."
Both the 1932 Ford Book by David Rehor references the bumper as part B-17757 and the Price Parts List V-8 and 4- Cylinder Cars 1928 - 1932, effective date December 20, 1932 (page 70) also shows the bumper bar as part B-17757. Any suggestions? |

Re: 1932 bumpers: straight or slightly curved?
Please re-read what you wrote as the bumper part number is five digits and the response you quote is for four-digit part numbers.

Re: 1932 bumpers: straight or slightly curved?
Steve/IL.
Thanks and understood... Otherwise: Just received an update from the museum. "The engineering release notes for B-17750, Bumper Assembly, indicate "Drawing Size: ND" (ND = No Drawing). We DO have drawings for B-17757, Bumper Bar, with dates from September 1931 - December 1931. There is also a drawing dated May 23, 1938. (Apparently, the part was kept in production for awhile, for service/replacements.) The 1938 drawing is FAR easier to read than the 1931 drawings." I will order the drawing. |

Re: 1932 bumpers: straight or slightly curved?
B-17750 would have included the bumper end plugs and not just the bare bumper.
I will be interesting to see what the drawing reveals. I hope that there is more than one drawing reflecting the two (at least) suppliers who made the bumpers for Ford, one with the large knuckles on the ends and the other with small knuckles. |
