Hi Vinny I think Tom will be right and you would be able to lock the windscreen partly open at any angle you wanted for ventilation, if it was balls between thr two halfs it would probably rattle closed as you bumped along the road ? Is there not some sort of model T forum or club you coukd ask someone to confirm what the original bracket is like.

the two photos are actually showing one hinge,
Easy way to make it is to use round headed rivets in the male half by drilling the holes then use a tapered pin reamer to open up the hole from the backside then drop the rivets in and one smack with a hammer your done, you need rivets I just bought a bag of a hundered cause I needed 8 .125" rivets .250" long. I can drop some in the mail ladys bag if you want. To press the indents into a piece of angle is going to take some pretty serious pressure. From looking at the two parts they were probably made in a drop forge press

I just did some googling and found some other style hinges and they're definitely NOT bearings. This morning right before I posted my "detent" comment above, I was picturing the two halves set up as detents with a bolt, spring and nut. The first few pics I found were of brass hinges, with detents (not round but rectangular), spring, bolt and nut. Almost identical to what I pictured. It's amazing what comes to my mind at work when taking a break with my e-cig looking out the back window at the parking lot. That's also where I solve my programming strategies.
Anyway, I'm going to need at least 50 rivets (I'll lose, drop or screw up a couple at least) so rather than take yours, where did you get them and I'll just buy a bag. Thanks for the offer tho! As to the indents on the other half, I'll just hit them with a ball nose end mill. I'll have some milling to do on them anyway. BTW, the photos are just both sides of the same one. I have two of the same ones here but the other is in pretty bad shape and wouldn't photo well.

Ok, I found some for about $11.50. Fastenal doesn't have them locally and although Grainger has them they closed the local store and the next closest is 20+ miles away into the city (read: heavy traffic). I'll be posting pics as this project progresses. Thanks again for the offer Dallen.

I spoke with a friend today who owns a model T stake truck and he didn't recognize the hinges in your pic. His has a piano hinge with a scissors mechanism to adjust the tilt.
The rivet idea is a good one, or if you already have the ball bearings, maybe you could drill some smaller holes to locate them and weld them in place from the back side. Tom ![[Image: TomsTechLogo-Profile.png]](http://tomstechniques.com/wp-content/uploads/2013/11/TomsTechLogo-Profile.png)

Just be sure that when you install the bearings, to put the bottom of the ball toward the smaller hole before welding them so they are standing right side up.

Tom, until Dallen came up with the rivet idea I was thinking about spot welding the bearings in the holes. Not sure if we have a spot welder at work tho - I assume there''s one somewhere on the complex but it's easier if it's in our own fab shop.
On the hinge style, I'm so far aware 4 different designs. The one I have here, two different mounting styles of those brass ones (they mount from the side instead of the front) and the piano that you mentioned. Wouldn't surprise me if there are more styles. |
