    I'm contemplating mounting one on my '28 RPU. I knew there was O'Brien who's repoping them.
    Now I just found out that Summit is selling one under the brand Cal Custom, is it a renamed O'Brien or a different one?
    If it's a different one, which one fits best?

  2. I have a brass one for a 26-27 T that I tried on a 28-29 cowl. Seems to fit pretty good. I'd make you a pretty decent deal if it interests you.

    Although two piece windshields on roadsters do not seem to be popular items here, I love the look and have loved driving behind mine for many years. There is much less air turbulence (noise) in the cockpit than with a flat windshield. The disadvantages are getting yourself to sit low enough in the car so that flowing air goes over your head instead of in your eyes, and the difficulty of designing a top that provides headroom inside, attaches to the windshield in a good way, and still looks nice. I encourage you to purchase a windshield, and make it work. Enjoy the journey. HFH. 3ADA05FE-7E6A-4538-8742-7DEEA1792DC2.jpeg

    Is that a Riley grille? your car looks super nice.
    I don't think it's gonna be a problem to sit low for me since I'm 4'9.

    Yes, it’s a Riley grille that was given to me many years ago. I’m also not very tall. I made my windshield out of wood, got a pattern maker friend to tweak it (for shrinkage) and brought the pattern to a local foundry for casting. Good luck with your project. It would be great if you could post some pictures of your progress.

  7. Not popular!?!?!?!! They are hugely popular but cost $$$$$ and take a LOT of effort to make work and look right. That is the only reason you don't see more of them. Always dug your car!!!!!

    Making a folding top,trick is the header and how to hook it too the windshield post{ all three is best in the case of this type windsheild. I was going too try an make a folding top for my Buddy's roadster,after he said he'd like one !;; I played around with ideas ,to help out, who has the 2 part type "V" windshield.
    Oddly to meo_O,was his resistance too putting small brackets or pin,of any kind near the top of post,,{ So asked,your self, know there has to be away of hooking the header bar down?} The other weird thing was his not wanting snaps around the rear cockpit lip ! too hold the top ether.
    I could not hold it by magic,so I did not make him one. Told him to find Harry Potter :D

    I needed a top for my own roadster,and I'm low $,so try to do all my own stuff.
    Here a tech I did years ago to help out any that may wish to try,may save a few mistakes an get some ideas.; https://www.jalopyjournal.com/forum...top-a-how-too-do-it-tech.857951/#post-9479688

    Evening. There was once a Model A RPU body builder. Let's say his name was Last Refuse. I bought a body from him, that was a story, but it came with his "Halleck, Duvall, style" windshield. That was not what I ordered, I wanted a regular glass. I have straightened out my issues and have a flat glass windshield but have never taken that one out of the box. If this would help you I would be in for $200. and freight.[​IMG]

    By the look of it I understand why you didn't take it out the package. Sorry.

    F-head, that’s a beautiful roadster that you built! I’m wondering if you still have it and if you ever worked at making a top for it. I have to also say that I loved seeing pictures of your ‘41-‘47 transformation. The chop improved the lines of the car immensely. You certainly got it right. Thank you for sharing pictures of your work. HFH.

    Hi HFH
    Thanks for the compliment, I sold the roadster around 10? Years ago, it lives in Spokane now
    Never built a top
    Still love the Hallock W/S though

    Hi Chris,
    Sorry you never got an answer to your question about where to buy a windshield. I think that any windshield will require a certain amount of fitting as I think gas tanks are probably not all alike. I live about 90 minutes from O’Brien Truckers. I have seen him at swap meets for many years. In fact he came to a car show for traditional hot rods in my back yard many years ago. I have always heard good things about him. And if you decide to make your own windshield as I did I am happy to help you. HFH.

    @jackandeuces Is that an O'Brien?
    @hfh I have a couple of complete Jaguar XK140 roadster windshield I could use one, but I really like the Hallock look on the 28/29, especially the way it blends with the square spots on the cowl.

  20. Dennis Obrien is a great guy that has done work for a lot of us on the HAMB over the years

    Like I said in my previous post, any of this style of windscreen takes effort to make them work. You will have to tweak the frame, the body or both. Read Dennis' description

    Hi Chris, if the Hallock suits you that is what you should do. I have no idea how the Jaguar windshield would look on a model A but you will probably learn something by trying it. Please post some pictures. Even if you don’t like it. Don’t be afraid of getting it wrong. Trying different ideas will lead to getting it to be right for you. HFH.

    I started out with a Hallock on my roadster and ended up switching to a chopped and leaned back factory style windshield. My Hallock was from Steve Sellers and Dennis O'brien bought his patterns. I'd buy one from Dennis if I were in the market.

    I’d make one out of 1/8” thick stainless with the glass sandwiched between, and held together with machine screws. Not necessarily a exact copy, but somewhat similar. Can do a lot of screwing around before spending $1400.00!

    You're right, but time is something I'm lacking between the customers cars and the farm to renovate, it's actually the first car I own on which I buy so many aftermarket parts, usually I fabricate or renovate old parts, this time around I simply can't afford the time. I much prefere spend $1400 on a windshield than $4000 (including $1500 in material) on an electrician to lay a main cable and 2 big circuit breaker box in a couple days. In the end I save $2500 and probably a couple days work over fabricating the windshield, if I was working 8 to 5 for the minimum wage it would be different, at least that's the way I see it.

    B2143347-0719-4E70-A4FD-79FD586DB3C1.jpeg These are the patterns I made about 30 years ago. I’ve made three windshields. The first one was bronze and the others are aluminum. On the windshield I’m currently using I cut the tops off the castings so there is no metal over the top of the glass. Milling for glass is done after the castings are made.
