The whole point of this thread is to get or replace' that part' part needed in the restore project.In some cases like this,a lot of  discussion is needed and I think it's to the benefit of all classic restorers.We want any who need a piece to get the piece,the right piece to help them along.Discussion,involving whatever that part might be,is certainly encouraged as long as the focus remains about the part requested and sometimes(like in this case) it's certainly going to take significant discussion to find the 'right' part.

Thank you for this. If it were just going to be as simple as "I need a _____," wanted ads in the classified section would suffice. Can you imagine trying to ask for the part Guido needed there?

Agreed. This thread has taken off in such a great way and discussions like this are a part of the "finding the right bobs and bits" process. As long as we don't diverge into a full discussion outside of the scope of the thread/ask then I think this is perfectly appropriate.

Mod input welcome. While this is not discussing the transaction such as address etc. it is getting lengthy on details. I'm not sure where this fits into the idea of taking this outside this string.

 

I pulled the stud from my Sears 4454 (middle stud in picture) and it matches your 4454 exactly as well as matching the mount for the recess area in the hub fork. 

It is the same length in all ways to my short stud with the reduced end diameter (top stud in picture), and the threads match. It seems you would need one of these short versions.

My short stud is the only one I have from a complete perfect (looks new) mount. I have to keep that.

 

My longer stud is the size I have an extra of. The threads don't match but are close and could probably be tapped over. I photographed it with a best fit position for comparing (bottom stud in picture). Worst case is you might have to cut off part of the top if too long, and dremmel a notch in the end for a screwdriver slot.  That would take the chrome off the end.  You will probably have to run a die on it to correct the threads. This could be tricky. You don't have room to run a die all the way. You would have to do as much as possible normally then reverse the die and work it on backwards which could fail. This will take some shop sense and experience to figure out. The long stud will not screw into a short stud hole without some thread mods. It looks like you could tap the hole in the RA housing tang instead. SO FAR your thread specs have not been confirmed but it looks like a mismatch for a long stud. 

 

I think it is worth a try if you want me to send my surplus long stud. Your drive might fit over the extra length and the threads don't need much but some.

I think that the longer stud will fit as well and if not, I can cut it down to size and use my Dremel on it. The threads will be no problem. I can run the die carefully and correct for the size. This stud will be the lifesaver for using the drive motor on the 6305 mount. I will PM you. Again my thanks. This thread is doing the job it was designed to do 100%. A great thread.

Is there any other missing piece? This is an ideal candidate for JBWeld. That is not really a load bearing piece.

I am looking for two of these circular red “Dynamax” stickers. If they are attached to the bearing cover/dec knob or loose doesn’t matter.

 

These will complete a Dynamax 6 and 8 for me.

 

Thanks in advance.

Thanks. I’m going to find a form for the ID and mold the missing piece  with PC Metal. But I would still like to line up a replacement in case the epoxy doesn’t work.

One of the declination arms on one of my refractors equatorial mount broke at the section that connects to the slow motion control mechanism. I used JB Weld (long setting time)  on it and it has been holding firm for several years now. It doesn't look pretty but is holding.

Someone here can surely describe how to make an exact replica. Good luck!

All - let's please take conversations about fixes and uses out to other topics so we can keep this thread as closely as possible related to asking for missing hardware.

 

Thanks!

so i just bought a unitron 142 at auction.  just the ota and tripod in their boxes but no mount or mount box.

 

if anyone has a 142 mount all alone , keep me in mind. 

 

conversely, before i incur the cost to ship this stuff home, if anyone by any chance has a set of legs for an r73 royal astro mount and for some reason would like to own a unitron 142 tripod in the box, i'd consider some kind of swap.  there's a pretty good chance i will be adapting the unitron legs to fit the r73 mount until fate sends a unitron mount my way.

This stud threads into hubs or locknuts so the nut can be tightened without tools, by hand. Anyone know what they are called, or where I can get some? Thank you!

try "machine handle" or "tapered lever handle" but they are described several ways.  mcmaster carr sells them.

 

you can also buy a shoulder bolt and have a machinist shape them on a lathe to suit.

Hi all! 
I was fortunate enough to receive an ATCO 1254 that I’m refurbishing. Looking for a .965 porro prism and diagonal. Not picky about brand. Thanks for your consideration!     FOUND!

I'm looking for a finder bracket for my ATCO 1254.  It has three attachment screws and it mounts onto the tube.

 

I have asked before in the want-ads, but without a picture it's hard to describe.

 

It looks like this:

I could make use of a carry strap and peep site for an Astroscan to complete mine.  I finally have a really sharp one in very good shape but it didn’t come with them.

 

Thanks!

A friend who's not a CN member needs a finder scope and bracket for a Towa 339.  He has the thumbscrews that mount it.

BOTH NOW FOUND!
