Guest John1918 Posted November 24, 2008 Share Posted November 24, 2008 Does anyone know the source for the Model T rim bolt pictured? My Ford friends are either don't know or won't tell but I think they come from a USA supplier. The Ford ones are cheap at $2 but are about 0.45" too short for the 1920 Dodge. If the source could be located it might be possible to get them to make longer ones for the Dodge. Length for the Dodge one -also pictured, is 3.25" counting the head or 2.875" (2 + 7/8 inch) bolt length x 7/16" UNF. The Ford one is high tensile steel.John Link to comment Share on other sites More sharing options...
JACK M Posted November 24, 2008 Share Posted November 24, 2008 A bolt is measured from the bottom of the head. Link to comment Share on other sites More sharing options...
platt-deutsch Posted November 24, 2008 Share Posted November 24, 2008 Could you buy Carriage bolts and just reshape the head on a grinder ? Link to comment Share on other sites More sharing options...
Guest BobD735 Posted December 1, 2008 Share Posted December 1, 2008 I wish you the best of luck locating the 7/16" X 3 1/4" long rim bolt. I need a few of those also.Carriage bolts have a low profile head, and are threaded the entire length. Link to comment Share on other sites More sharing options...
Guest John1918 Posted December 1, 2008 Share Posted December 1, 2008 I am using 3 inch high tensile bolts and they are OK for the job. I turned the head down a bit but it doesn't look like the real thing and they haven't got the square to stop them turning when undoing the nut.

Guest simplyconnected Posted December 1, 2008 Share Posted December 1, 2008 I just spoke with a cold-heading company that makes them for the Ford guys. They will do a 'run' of 3" (or 3-1/4")length, but I don't think you guys can use that many bolts. Maybe if there is enough call, we could make this happen.Dave Dare Link to comment Share on other sites More sharing options...
72caddy Posted December 1, 2008 Share Posted December 1, 2008 What was their minimum order? Link to comment Share on other sites More sharing options...
Guest simplyconnected Posted December 1, 2008 Share Posted December 1, 2008 Set-up time is what we're paying for. A National cold heading machine pops them out so fast you can't even see it happen; 10,000 bolts with rolled threads in one hour. After that comes heat-treat and plating. End result is a perfect, hardened bolt, made to exact dimensions.They already have the dies, but it takes a few hours to set up the machine for a run (-which is a lot of work. A crane lifts the dies.). The actual production time for this run is nothing.If there isn't much demand, the only other alternative is a screw machine operation where the bolt is cut from round stock, producing a much weaker bolt.What is the correct length needed? 2.875?

gboy Posted December 2, 2008 Share Posted December 2, 2008 Depending on cost I could use 100 - 200 bolts, I know there are people out there needing these bolts. We need to get the word out to our DB brothers. Link to comment Share on other sites More sharing options...
nearchoclatetown Posted December 2, 2008 Share Posted December 2, 2008 The DBC newsletter would be the place to do a survey. Are you going to Rockwell an original bolt or have one tested to make sure the new ones are strong enough? Link to comment Share on other sites More sharing options...
Guest simplyconnected Posted December 2, 2008 Share Posted December 2, 2008 We'll make them the exact same hardness as the Model T bolts. This company has lots of experience making them. I love originality, but quite honestly, these bolts will be much better.Did you see the picture at the top? Looks like a Blacksmith made that top bolt. Today's steel is much more defined, which makes heat treat much more effective.Remember, the bolts need to be tough, NOT HARD! Glass is hard, and therefore brittle. We case harden, but leave the inside tough, yielding much higher tensile and impact strength than the original bolts. Link to comment Share on other sites More sharing options...
nearchoclatetown Posted December 2, 2008 Share Posted December 2, 2008 I understand what you are saying. It just scares youknowwhat out of me that there was discussion about useing normal carriage bolts. Link to comment Share on other sites More sharing options...
Guest BobD735 Posted December 2, 2008 Share Posted December 2, 2008 In your quest to provide a rim bolt of the correct size and structural integrity, you might want to consider that other car manufacturers of the 1920's, who used the same Kelsey 32X4 rim, also used the same rim bolt.Rather than limit your survey to Dodge Brothers needs, through the Forum, you might want to provide owners of Chalmers, Essex,Studebaker, Hupp, Paige, Scripps Booth, Packard and Hupmobile, the same opportunity.

Guest BobD735 Posted December 30, 2008 Share Posted December 30, 2008 I contacted Ed Labounty. He was able to provide me with the rim bolts that I needed. Thanks for the tip Jack.Bob Link to comment Share on other sites More sharing options...
