This is one of the linkage arms for a dual carb intake I have on my '36.....any ideas on how to fix it so it might last? I've not had any luck with finding these sold as a singular piece so just trying to see what might be a good fix for this.

I know nothing about 3D printing, but would it be possible?
 
I would think if you can clamp it around something similar in diameter and then “V” out the crack, you should be able to weld it up and grind it back down to look pretty factory.
 
aluminum? guessing off inner web pictures. Worst case some zinc based pot metal. Probably can be weld repaired. If not that is a fairly simple looking piece to reverse engineer and machine.

Carb Linkage Arm for Holley 94, Stromberg 97, Rochester 2G

These extended throttle shaft arms are cast in the original Eelco molds from the '50s. The shaft hole is 9/32" for the Stromberg and Holley 94's but can be used on the Rochester 2G if you run a 5/16" drill through the shaft hole. The top hole is 3/16" and fits all of our linkage parts with the...

I'll have to look check those out!

I'll probably use a combo of @skyhighZJ prep suggestion and @Tom@Hilltop_Machine JB killer weldz and see how that holds up.

Anybody ever try and make something with a sand cast?

You'll have more in JB Weld than those parts cost... new... unbroken...

plus any welder worth his salt should charge double to deal with that stuff.....well they do anyway. It will take twice as long to clean that mess off.

Some guys like the OEM/NOS/period correct aspect though. I have a buddy who literally just had some drum brake springs repaired for a concourse 73 Camaro. Then you also have the sentimental weirdos out there that like to keep things the way they were when they're daddy gave them the keys. I've been guilty of it myself with my 96...spend 10x more on something to refurb it, than just go buy the new one...because the one on the truck is the one my dad bought.

this is exactly what I was thinking.
I don't know what kind of stress this part is under but if it were made of nylon would it not work?
I could make it :D

Probably not too much stress, just need be able to clamp down on that rod and not move when I give it gas. It's in close proximity to the exhaust headers below so that may be a limiting factor to how long something printed would last.

Alumaweld rods.
Clean it, vee it, grab a propane torch.
 
Found this aluminum piece hiding in my jeep glove box.....Might see if I can whittle a replacement out of it. The linkage from Speedway are 1" shorter and for a different shaft diameter so I'm holding off on those for now.

I’m all for dabbing somehting do the I did that factor.

Just wanted to make sure you did see that speedway has about 4 different sizes and styles available
 
Unless you just need that look, you could just take a piece of 1/2x3/4" flat bar, drill the two holes at the correct spacing, grind down the small end so the nut gets some thread, and put a set screw in the big end.
 
Here's a nice manucad rendering:

I'd like to retain the look....for Right now if can get both carbs working together I'll consider it a win . Aluminum is gonna be easier for me to shape with the sawzall while @jcramsey holds it for me :laughing:. There's actually another main link that may be easier to replicate.
