    C1's Texture or No Texture ?

    I recently started a thread about windshield weatherstrips and the two ribs found on originals. Thanks to all that responded with great pictures.

    Although my original post was pirated (apology accepted) by a discussion about whether C1 steering wheels had texture "grain" or where they smooth from the factory, I decided to move this topic to another post because I found it to be worthy of additional discussion. The way I look it, we are here to share and learn and if possible add some clarity to some of these debates as long as the evidence is convincing and credible.

    To that end, I would like to enter some evidence that I believe is pretty compelling and very credible. Through my original post I met another NCRS member who happens to own an original, documented 24,000 mile 1957. This is a four star Bow Tie (headed for #5 in San Antonio) and was featured recently on the the cover of the Restorer magazine. He was gracious enough to take some pictures of the original w/s I wanted and was willing to do a little detective work on the steering wheel dilemma as well. This car is the real deal and is well known by many. The VIN is 34** and is an April production car. As I have learned over my thirty years in this hobby, there will be opposing viewpoints even when the evidence is clear, so let the games begin. BTW- these pictures show front facing surface, back surface and spoke areas. I do have more views, but thought I would start with these four. Once again, thanks to the owner of this car for playing an integral role in advancing this discussion further.

    Re: C1's Steering Wheels-Texture or No Texture ?

    no doubt in my mind that grain was present on original, factory installed steering wheels. i once got to examine a NOS over the chevy counter 56-7 red steering wheel that was purchased in the 60's and was still in the old black and yellow gm box. the grain was evident and deep. he wouldn't sell it. all 3 of our 57's have or had graining before i sent one to have restored. i've got a beige wheel around here somewhere that is a POS but its still got some grain under the spoke attachment area of the wheel. mike

      Garry: I have owned my 60 for over 43 years and like Mike my original wheel although most of the grain was missing there was still some visible grain around the spoke area. Since then I had the wheel restored.

        Garry, Appreciate your new thread. I'd have started one but have been away. I asked this question here years ago but never got enough of a response.

        Thanks for those remarkable photos. Quite obvious to these eyes. Yes I see it and believe it. Mike and Stephen, also thanks for your input.

        If David has the prints, I'm wondering if those revisions had something to do with a variation to do with this. I'm convinced I see it in the pictures, but why on earth are some without grain. I have seen so many without grain. Is it possible that all of it wears off in use? Seems unlikely, especially behind the area at the end of the spokes. I'm baffled.

        David, does the print describe what the material is? What type of plastic?

        But this brings up another question regarding the cracks I see on the wheels. Maybe those cracks were once the grain and with age have shrunk or expanded. In other words, the texture/grain features turned into the cracks I see. re there any plastic/chemical engineers out there that can opinionate?

        This is a original 1956 wheel.


        This from my '59. Those features you see are actually cracks. But maybe they were once grain?

          Re: C1's Steering Wheels-Texture or No Texture ?

          Yes, I am the guilty party who pirated the weatherstrip thread. Sorry about that but the comment about grain vs non grain was too compelling to ignore. As I indicated I was surprised there was any question about grain in C1 steering wheels. Page 14 & 15 of 6th Edition of J G is correct with regards to having grain, unfortunately it does not show a picture, probably because they never saw one. Will repeat my comments: The C1 Steering Wheel and Horn Button Ass'y was made by Inland Manufacturing Division of GM, Dayton, Ohio. It was released for production 9-27-55. The blueprint indicates it was redrawn on 5-16-57 and 9-11-57 with NO change. On 3-14-59 there was a slight change when part #762551 was replaced with #764837. This was only a screw & washer ass'y located on the horn button contact. The print does not specifically mention grain in the mold ass'y #76087 but there is no doubt the wheel did originally have a grain texture. If I can locate, I do have an excellent colored photo of the grain in the wheel from '56 #009 removed at Sebring and never used. Would offer the photos use in the 7th Edition of the 56-57 Judging Manual but I doubt the "hierarchy experts" will accept since they have implied on an unrelated 56-57 Production Number subject that I "have not kept up with the ongoing research".

            Re: C1's Steering Wheels-Texture or No Texture ?

            Rich, et al. Shoreline beige and Venetian beige wheels are more prone to cracking along the entire surface than any other colors. All colors tend to crack with larger cracks at the spokes area. Both of my 62 bow tie cars have significant amounts of grain on the wheel. The fawn one, wrapped in a leather wrap from January 64 until I removed the wrap in 2012, has grain around the entire wheel. Not nearly as prominent as reproduction grain however. Almost every ORIGINAL 56-62 wheel I've looked carefully at (150+) have had graining both front and back at the spokes area if not elsewhere.

              Does the blue print show the change difference in the holes beveling of the spoke holes?

                  Dave,

                  The 56-7 wheel spoke holes were slightly beveled, 58 and up spoke holes had straight edges and not chamfered.

                        LOL....I have my fun some day I'm sure.

                        So I'd still like to know why my original wheel has no grain(the red one above). I've had it 31 years. It looks exactly like when I bought it. The wheel didn't have any texture/grain then.

                        Here's the reproduction, offshore, POS wheel for a '61 I have here. I absolutely positively hate it. The grain is cheesy, seam around the perimeter, soft feel, overall just a yukky wheel.

                          You apparently had your fun this weekend. What a great experience that was for you. Congrats again on a great car. Your documentation and ability to tell the story over the whole process was as meticulous as your restoration prowess.

                          Somewhere I have the name of the guy in MI that restores steering wheels. I believe his name is Richard Dunham although I could be wrong. He did a beautiful job on my original '56 wheel several years ago. Have you spoken with him on this topic?

                            Richard would tell you that they all had grain originally. He and I have spent plenty of time driving to Regionals and discussing Corvettes.

                            Recently he saw a 58 wheel with chamfered holes. He wondered if it may have been an interim wheel or... as a former GM engineer with us noted, if the GM tooling was just wearing out which is the real reason later wheels have no chamfer.

                              Patrick,

                              As per normal production stuff, they used up what they had on hand before installing the new stuff. In 56-7 there are some prime examples of that one of the best was the late Dave "Fergie" Ferguson last 50 1957 which had some early '58 engine parts and also '56 parts on the car.
