Hey guys,

Just wondering what is the proper way to fabricate the anchors used to attach a tube. Not sure what they are called, but you see them all the time.

I have been welding a washer to the end of a tube, but I'm not too thrilled about welding zinc-coated unknown-grade washers into my structures. For larger diameter, I was thinking of just making circles out of steel plate.

What do you guys do?

Thanks!

(the little buckets).

 

Turning them from round bar would be "proper".

 

Ah ha. Thanks!

 

You would find a Mill and Lathe pretty handy for what you are doing

 

If it is a one off, I've used grade 8 or metric 10.9 washers and bead blasted off the zinc before welding. The lathe method would be ideal since you could make it nice and thick but VERY time consuming.

Best method is laser in my opinion but that just isn't practical for the normal fab projects.

Here are a few we did a while back:

 

ill use grade 8 washers for anything that isnt going to see much load. anything else and ill either use 1/8" steel or chromoly if neccesary "washers"

 

nice work nrg

 

I could bang one out on a lathe faster than you could cut and weld one, a lathe is much faster, if you have a good lathe with good tooling and the proper knowledge on how to use it.

 

You make those on a lathe. Drill, bore, cut off.

 

Thanks for the ideas! I don't have access to a lathe or mill, so I guess I'll just have to make them by hand for now.

 

go buy yourself a cheap import lathe?

 

I practically have to get a loan to pay off my electricity bill, the lathe will have to wait.

 

that sounds like a hefty hydro bill markku.

i make mine out of solid round stock. i have a couple lying around if you need them quick. if i don't have the size you want, i can proabably make some up.

When I did work for Lonestar Racing, the "anchors" they used were made from round bar, and were about 3/8" thick. Half of it (3/16") went inside of the tube, the part that went outside matched the od of the tube, and had a pre-machined bevel for welding. And there was obviously an appropriately sized hole in the middle.

They were freaking rad.

Pics for clicks, not the anchors, but shop pics. This place was pretty cool.

Most are threaded for rod ends but maybe they would work for you application....

aww that sucks man

well let me know if you need any little parts made. I have a machine shop in my garage, and i am in Canada so shipping won't kill...

 

i could prob make 2 dozen on a lathe in an hour. no joke a lathe would be fast for that purpose

 

Yeah same concept, but obviously not as deep

 

yea for that type part i make a stepped washer on my lath.its not very time consuming.drill the hole cut the step.part it off.

 

just outta curiousity, have you checked mcmaster?

Not for one off stuff. Maybe if you had every size OD bar stock laying around. Tell you what. You start off with a piece of 2.00 or bar stock and I'll start out with a piece of .125" cold rolled sheet. We can both make a 1.5" washer and lets see who is faster

Now I totally agree if it is a job where you will need to make a quantity. But then again, at that point why not have them laser cut for under a buck each.

 

How much would it cost to say......have 70 made with an o.d of 1.25"
and a hole size of 10mm on a lathe and roughly 1.5" tall? Also have the base/landing be say .1 thick and the walls be around the same

 

we have a similar part that we use on the upper a arm.the price is around 10 dollars for an order of 20.it would be even cheaper if you went to 70.the cnc laths can jam these parts out in no time.

 

What machine shop does work like that for 50 cents per piece in small quantities. You must be providing the material at least.
