Great get Steve! I saw your ad on amart for a eq head box, any luck with that? There was a discussion on here a while back about somebody making a copy of the box. Does anyone know if that ever happened? Pete




that was me...i had a friend make some of the old style
that would fit the mount that the cradle would not
come off.
had to do minor tweaking but they worked out fine.
sold a couple and sadly only have one left.
congrats on a good score...cant wait to see restoration on this one.
heres a picture of my custom box.

I bet that was a relief. Now lets see if you can get it back in I have had a few where they came out and then for some reason would not go back in without jamming up.




Maybe a little wet sanding will smooth things up.

Thanks guys -
Yes, wet/dry sandpaper should do the trick just fine.

Brian, thanks about the box. I do have someone that offered to sell me theirs. I am double checking with them if it is for a mount that the cradle is fixed.

That is a nice looking box Brian. Maybe I should you buy some mahogany and get out the table saw and see how hard it would be to make one. Are the corners joined or just glued together?

Did your freind make them for plans or did he make them with an old box as an example?

Have spent most my free time working on the mount. Went to move the counterweight to a new spot and the "top" popped off. Amazing all the times we moved it and hauled it here it never came apart, and I never noticed. Always surprised I didn't have 2 weights with this...

Oops, let the cat out of the bag. That has a new happy owner. I traded the mount for another scope I really wanted. Need things to look at and things to look through. I think you know what I mean That mount got me a triplet refractor that when I compared it to some other scopes I have, I quickly sold it. I want that 4" mount back

Your confusing me, so you have this light - http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/5482599/page/0/view/collapsed/sb/5/o/all/fpart/1 ?

But not the mount? If your light is extra, please send me a PM.

Starting working on stripping the mount base today. Anyone out there painted one of these before? Happy to hear advice on having it powder coated vs. "rattle can" spray painting. If I powder coat it, I will have to strip the upper portion of this piece as well.

you can use the black epoxy paint that they use to paint car springs with. Use 400 wet sandpaper to feather all edges between the unpainted area and old paint. It also would be good to use an automotive primer before painting. Paint using very thin coats to avoid runs. Patience and effort will provide excellent results.

also, make sure there is not lose paint left. Use a brass brush to clean the base completely.

Steve just strip it with Jasco and paint with black primer maybe some filler, then sand and paint it with rustoleum satin black it looks as close to the original paint as anything out there. 1954 155 some parts are original and some needed paint. You can't tell which are which. I use rubbing compound and wax when the painting is done to finish it off.

Re: Powder coating new [Re: sgorton99]
      #5494160 - 10/29/12 07:10 AM

Stuggled with the question of powder coating vs spray as well. I ended up spraying my Unitron 152 OTA because I was afraid of what the heat of powder coating would do to the baffles. But I went ahead with powder coating the mount because of the knocks it is likely to take during use. Having said that a big advantage of doing a spray job is that it is easy to touch up and if you take care you will end up with a finish like Clint's. I will be posting some pictures of a powder coated mount in the next few days to finish off the Unitron 152 restoration thread I started a while ago.

For those of you on the East Coast: I know there are quite a few Unitron aficionados looking up at the skies as Sandy comes into view. Good luck Guys and I hope the meterologist predictions turn out to be incorrect or at least wildly pessimistic.

Stay Safe

Jon
