Hot Rods Typical roadster windshield frame wall thickness

Can anyone tell me the tubing wall thickness of typical late teens to mid 20s roadster windshield frames, or know of a source for the channeled tubing the hot rod vendors use? I'm building a 1917 Dodge Bros cut down phaeton to roadster. I know it's out there somewhere, I just can't seem to find it. Thanks.

 

The hard way,is make it your self
;; 1/2" EMT [ sand off the no-rust topping] ,cut 5/16 to 3/8" slot;; Can be done by, make jig to hold it,and run a diskgringder blade through one side< for glass with lots black RTV silicone filling the tube so glass is held well{ clean up smooth/add RTV as needed.
Or,find some small box tube [ 5/16 or 3/8 box,cut off one side= slot,weld into 1/2 EMT done as above/ then same with RTV; but less RTV to hold glass { remember to use 2 layer safety glass }.
That is fairly close tom what I had to do,too fix a rusted out frame. I'll add a photo,when I find it.
Ok; pic,,This was before welding a lot more spot welds,and then cleaning up welds. { by the way,Box tube side cut off with band saw.

 

Try these guys. I just checked the listings, and it didn't show your vehicle but, They have extrusions and build windshields that are not on the market. You'll be surprised at what all they still do.

 

Sounds like you are looking for the first, but I threw in the other two also.
You have to consider how the glass and channel/frame are going to be attached.

@Pist-n-Broke thanks for the link, I had not heard of them before.

 

Alright, thanks guys! Dana Barlow,puhleease don't overestimate my skills!

 

No problem Rod, Click on the link then go to Resources and then to Windshield Channel Cross sections. There are shapes of all the frame profiles they can roll form. It's way kool. Hard to believe anyone is still doing this. I had them build me a new frame for my Rockne Coupe. I had been hunting for 30 years and once I found them, they just made me a new one. You can't beat that.

 

Dana; That looks Painful, Time consuming, Difficult, A major Time Loss And a Ton of finish work. There profile 1378 or 3 would have done the job for you in far less time and the material is Chrome Shop Ready.

I'll use this picture to illustrate the difference between DIY and pro.
Yes, this was a very low end DIY, and the pro is chromed.

 

7/8" of 6061 t6 aluminum round bar stock , method of choice to cut a 3/8" slot , miter the corners & machine screw together , used thin bicycle tube for bedding , been together for 25 years without problems .
I used my table saw with a jig to cut the channel , 9 passes to get 3/8 by 3/8 , power miter saw to cut corners with a jig .
As R to R says CCR now sells an extrusion ( about a year after I posted what I'd done on the T bucket forum ,I'm sure it was a coincidence) wink wink
Use blue loctite on SS fasteners in aluminum , I've found it prevents corrosion

 

Yes, whenever you are screwing one metal into another and you want to take them apart again, it's a good idea to consider various coatings. I got out of car service work years ago, but noticed GM especially was coating a lot of fasteners. Bikes have used this for decades due to vibration more than electrolysis, but our stuff tends toward lots of NVH too. I'd say this is one modern process that is wise to incorporate into our trad builds.

 

Yup, Over the years,I've used the hard way a lot,; Time* n welding stuff* I had,a long with lot of scrap metal * to make things ,but often low on the $ . I feel good about making stuff vs buy it.
