Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Looks great !!! Now if you could only print that out in steel !I 3D printed Peashooter’s model today. Had to give my new printer a test drive.

Not strong enough with the material I used as it limits the “infill” to save on filament. I’ve never done stress analysis on PLA filament, which is what this printer uses. I doubt using solid fill would be strong enough. Although this gives someone a working model to make a jig to make their own bracket out of steel pieces and possibly a model to create a mold or possibly even directly “investment” cast with. They do make stronger filaments but my machine wouldn’t support them. It would have to be professionally done.I am very limited in knowledge of 3D printing. What type of material is used to do the printing? Is it strong enough to hold up to the stress of the braking system? Or is this used to make a mold to cast a metal part? I thank you for any information. This is one of the few parts that I need to complete my brake conversion.
Much easier to do if you got fab skills and abilities. Unless you have access to CNC equipment or people that can cast it for you. Not cheap if you have to hire someone!!!Thanks for the information. I have been planning on making my own bracket out of steel, just did not know if this was an easier solution.
I can fab it. It is just the time it will take to make sure everything works right. My brother has some friends that have CNC equipment that might be able to help. Always looking for an easier way to get it done faster.Much easier to do if you got fab skills and abilities. Unless you have access to CNC equipment or people that can cast it for you.

The only problem with any type of casting is you need the "pattern" to be larger then the finished product. This is due to "shrinkage" , and I'm not referring to "Jerry Seinfield" either ! I used to cast aluminum and brass back when I had my own small foundry. I still have some "molds" my father made for me. He was a craftsman carpenter.Not strong enough with the material I used as it limits the “infill” to save on filament.

East Jordan Iron Works is still producing them here in Michigan , as a matter of factThis is just a thought. I know that manhole lids and storm drain covers are cast in India. I do realize that those aren’t high precision compared to this bracket. I’m wondering if it would be Possible to get a company to manufacture it over seas.

It’s on grabcad. Just set up a profile with them and download it. If not I can send it to you tomorrow when I’m at work.Do you have that file?
I want to see if that can be made without casting/printing.
It CAN be made with a water jet or laser or plasma cam in pieces, then figure out how to assemble it all together as a weldment. It would be a G-code nightmare for CNC and casting wouldn’t be cheap or easy either.Do you have that file?

I agree that a weldment is likely the best way to make this in the safest fashion for the lowest cost and in the low quantities that realistically would be needed. A 3d printed jig is a great idea and having the printed bracket will let you verify that everything important lines up right.It CAN be made with a water jet or laser or plasma cam in pieces, then figure out how to assemble it all together as a weldment.

I’m thinking if I can’t get my hands on one of these brackets I will use the 3D printout to make a welding jig.

Check post 145 for pictures and more details: https://www.steelsoldiers.com/showt...ering-Thread&p=2068376&viewfull=1#post2068376I see that this bracket discussion is still ongoing. Don't have time - mood to go through the entire thread again but how many pieces we are talking about and estimate for max price?
My son does special blacksmithing orders for all kind of historic things, especially small order sizes. Below some pics of suspension brackets he made for a very accurate replica of the first electric trolleybus for the Czech Republic at the beginning of 1900. The pieces are about 32 cm high, weighing several kgs and very sturdy, as you can see.

I am not sure if he would be interested at all, but before asking I have to know a bit more details.
