550 bellcrank old style


Recommended Posts

You should be able to use the new style and just not use the fail-safe rod through-hole feature.

My machine started as a 550, but I upgraded to the fail-safe rod when it came out and like the added assurance that the powder bar returns. Might be worth considering adding the fail-safe rod retro-fit kit.

Grump, I am a partner in a fabrication/machine shop. I could easily reverse engineer the product and laser cut it. That's not what my question is. It takes several hours to even get the digital data base, and make a prototype, all at the expense of making product for profit, which we would be losing screwing around with this one off item. I'm not someone who spends 60 hours with a file and dremel... if that's what you mean.

We spent over 800 hours on this similar solar tracker project and still lost money on the prototype contract. The old saying is still true, not all money is good money. I have to pay my employees by the hour, plus benefits, plus cost of the 10,000 sq ft shop operation. Somewhere along the line, my partners and I have to make a profit. Between design, programming, fabrication, testing,we lost a bunch of $$$. It's always cheaper, faster and easier to buy the original part. The photo is not our own, but a similar project. And, no, this one didn't work either....

Not if the original part is no longer made.

My shop can reproduce any part on the planet ever made, even the original Luger in .45acp, but not for a profit, but for a huge loss. I'll never pay off the machines in my lifetime, let alone anything else in the shop.... And this is just a little nothing stamped part. If it's still available, it's far easier to buy it.

Stand-up band-saw and a polisher would be faster. I think 2 hours if you paint.

This is the very first version of the bellcrank, introduced in May, 1985, and discontinued by 1988. No originals are available. Are you trying to maintain the original initial design, or make the powder measure function?

My thoughts exactly.

Or, you could just use your old one as a template and cut the fail-safe rod through-hole lobe off the "new" one you have in the picture.

Another alternative is just don't use the fail-safe rod and it will function just like your old one. The only difference between the old one and the "new" one in your picture is the extra material on the bell crank for a through hole for the fail-safe rod. It isn't like the new-new current ones that don't use the spring return.

I'll try to remember to look through my old parts box and if I still have the old bell crank it is yours.

I know this is a little old, but all you have to do is cut it in half.  Takes a couple of minutes, I've done a few of them.

I know this thread is a little old...  But...

 

Does anyone know what Dillon part number this is?
