Would anyone know where I can get stainless steel counterweights for my Atlas mount. I realize it would be for cosmetic purposes only but I'd like to find some if I can.

If not then another choice may be to find the cheapest stainless counter weights available for any mount and have the center hole sized to fit your counter weight shaft. If your cw shaft is thicker that makes it easier since you can just take it down to a local machine shop and have them drill out and smooth out the centers. If your cw shaft is thinner I am not sure how they would work it out.

Edit: Here is something to consider. Thread

The easiest (but not the cheapest) way would be to adapt a Mach 1 1.125" counterweight shaft to the mount. Then you could easily use the relatively inexpensive (around $100) AP SS weights.

If the shaft is thinner, the easiest way to adapt it is to have a machine shop make a bushing to press-fit into the existing hole.

I actually just finished making a custom steel counterweight out of an old flywheel for my AZ/EQG and made the center hole bigger on purpose so I could put a plastic bushing in to avoid marring the counterweight shaft. Also tipped the tension bar with brass for the same reason. :)

The stainless steel weights I've used here (and those I've seen) have a brass or bronze bushing already pressed in. I guess you'd have to push those out and replace them with ones using a smaller inner bore. Then come up with longer pin bolts, drill and tap the bushing, etc...

That would be like chrome plating a fracking AK-47. ;)

I'm a failure at anything mechanical and electrical and doubt that I could do anything with the excellent suggestions everyone has offered. I had looked at Robin Casady's page and taking a cue from Whichwayisnorth's link, I emailed Robin to see if he could customize them and how much they would cost. I'll post back if and when I hear from him.

Perhaps he has something in the ID you might be able to use?

I got a reply from Robin. Unfortunately he is not making any new stuff and just looking to sell off existing stock. He only has 5 lb weights. If I get them customized it would work out to $451.00 for 4 weights. I hope there is a less expensive solution elsewhere.

I think they look cool but I'd rather just use the Orion CW's and use the extra money for other accessories, but that's just me! I even use the 7lb CW that is made for the Sirius but it works fine on the Atlas mount.

I hate to say it, but the AK-47 is chrome plated where it counts.

What's this about Robin Cassady just selling off his stock. He's shutting down?

Is that a good thing? or A bad thing?

Like the AK, the Atlas is a plain Jane tool, more a Timex than a Rolex...

Got ya!
Although, I find that stainless steel counter weights greatly reduce my exertion and stress of moving them compared to painted weights which can scratch or chip so easily. Same with an anodized mount head, you can put it down without as much fear of damaging it compared to a painted mount.
I hated (and sold) my Tak EM200 mount because moving it without doing damage took everything I had physically, the mount was like a 43 lb, (with saddle & pier adapter bolted on), painted faberge egg, nice to look at but hard to keep it that way.
IMO non painted surfaces are a big plus when dealing with heavy things like mounts.

This is what he replied in his email:
"That could be done with the 5 lb. 5" dia. counterweights, but I am almost out of all other sizes. I have decided not to make any new parts and am just selling off what I have in stock. The counterweights have a brass bushing pressed into the bore. We can remove the existing bush and replace it with a custom bushing if we know the exact size of the counterweight shaft.
Cost for doing the custom work is $75 setup fee + $15.00 per counterweight. So, the more you do in one setup the cheaper per counterweight. Add this to the $79.00 price of the counterweight and add shipping.

Thanks,
Robin"

Sounds like he is.

If its for the atlas az/eqg (or if the atlas has the same 25mm (1") countershaft), the 1.125" bore counterweight will work fine.

I ended up getting brushed nickel plating done on my Atlas counterweights. May not look as nice as stainless steel counterweights but not bad either. I'll take some photos when my mount comes back from Orion.

Darn! didn't know Robin Casady was closing shop. His counterweights were and are a good alternative to vendor weights. The spring-loaded brass plunger is something nobody else thought of doing.

Honestly? Spring loaded brass plungers have been around for a very long time. I have some 14 year old stainless steel counterweights with spring loaded brass plungers that were not made by Robin Casady. All Software Bisque counterweights for the Paramount GT-1100S, ME, MX and ME II have them.

Oh. I stand corrected then. I haven't seen any vendor CWs with those springs that keep the brass plug from blocking the CW hole..

I was thinking the Meade LX80 counterweights at $30 a pop. But they are 1.125"

It's a sad day, Robin Casady was awesome. Best plate I've ever purchased and totally worth the cost.
