Big move coming... Multi-Group post

Ken
 

Hi Guys,

I recently retired and find that I not have the resources to continue living in Illinois due to several factors. Among them are continuing medical expenses incurred a few years ago when Rose came down with cancer. At that time I had to sell my 26.5 inch mirror, grinding machine, tools, HAM Radio equipment, etc to pay some of the bills. In all, the recent economic downturn, lack of sufficient savings, increase in the cost of living coupled with lower than expected retirement income is causing us to rethink our futire. One sad story among many I believe.

Because of this, we are hoping to relocate to Costa Rica. In order to do this, we are going to sell our home. Sell, give or throw away EVERYTHING we have left that we don't anticipate we will take down to Costa Rica with us.

I still have many books, a 10 inch refractor lens assembly with fiberglass OTA, 2 ea 20X3 inch Fused Quartz octagonal shaped disks to be generated round, Vacuum deposition equipment, Telescope making and HAM Radio parts, Tools, etc... much too too much to list individually here in the time we have left before departure.

I have saved this stuff over many years with intentions of doing something with it. These are my treasures and are too good to throw away but I know that I will not be able to move it all individually on Craigslist or eBay and really don't relish the thought of parting it out to strangers. I have had to come to the realization that this stuff is just that... just stuff.

So... If you have a truck, a few dollars and a plan, get in touch, make an offer. For the larger items that sell, I might be enticed to deliver as long as it's not a negative cash flow for me.

If you want specific information regarding what I might have for sale or to give away and are interested in picking it up or having it delivered, please contact me directly.

Thanks

Ken's Pre-Estate sale, Vacuum controller - SOLD

Ken
 

Granville-Phillips Vacuum controller and Gauges have been SOLD and are headed to Andrew in Sunny Florida.

Still have the 6 inch Diffusion pump stack of equipment seen on page 2. Looking for offer, if none received, I'll put it on eBay next week.

Willing to work on shipping and possibly meet half way or ???

Yep, and all fitted to the chamber and stand, but sadly still in storage, was just about ready to do a first pump down test when I had to move, three plus years ago. I NEED A SHED!

Drew, the hurricane was ~1100miles north of my present location, thankfully! Didn't I help you install those baffles? I seem to remember doing something along those lines.....

Well I guess it's about time I got my gear packed and headed off to uni.

Vacuum pump oil

Ken
 

Just looked and there is a wide variance in price for vacuum pump oil. Probably the best deal was 4 Gallons of Robinaire Premium Hagh Vacuum pump oil for $71.99... That's only 18 per gallon. Also say same item for $110.00 shipped free.

Wait until you spring for a gallon of Dow 704. It's like buying a good insecticide. Cheaper to vacuum coat the bugs.

Have fun.

Ken - KB7H
Re: Baby George learns to sprint

Ken
 

Yes...

I bought 2 Gallons of Robbinaire High Vacuum pump oil on eBay a couple years ago I think it's used on refrigeration pumps mainly but would work OK in a pinch. I also have a half liter of KRYTOX and somewhere (I haven't run across it yet), almost a gallon of Dow 704...

I hope that hasn't disappeared like my box of filaments, feedthroughs, view ports, etc. I hate it when I can remember having something but not where I put it for safekeeping.

Ken
 

New album posted today. Ken's Pre-Estate sale - page 2.

Showing the 6 inch diffusion pump, various valves, cooled shevron baffles, stainless baseplate (20 inch), and pool filter bell jar.

This is a project, not a kit. Everything will need to be disassembled, cleaned and tweaked, reassembled etc before being able to be used but this collection of components is a very good start towards having a working coating chamber.

Not shown in this group of photo's is the Hy-Vac 28 mechanical pump that goes with this setup.

Someone make me an offer then be prepared to come and get it in central Illinois or make arangements for me to meet you half way or ???.

Hi Gordon,

I am just looking for a diffusion pump which is capable up to 600-1000L/s.
I have seen you have two pump for the system.Does one of them separate for sale?
If yes what kind of diff. pump is that?
Sizes ect..

Hi, Everybody!

I bought an old CVC coater a few years ago, intending to fix it up and start coating telescope mirrors. But I got too busy making the mirrors, so this coater project has languished. Now it's time to sell this to somebody that has the time and energy to put her back into working order.

The bell chamber is about 23.5" in diameter, and about 27.5" tall inside. I am including a rebuilt roughing pump, and a rebuilt diffusion pump, neither of which has been used since I bought them. I did run the roughing pump for a minute to make sure it would pull a vacuum. There's also a bunch of stuff like coils, aluminum pieces, SiO, diffusion pump oil, an evaporation boat, a fixture and so forth.

I have a write-up on the system, plus many, many photos on my Web site at . Click on the coater item under the "What's New" area at the top left of the page and have a look. Enjoy yourself, and feel free to make any offer on the system that would work for you. It's gotta go, so if you want a good coater project, this is a great opportunity for you. Thanks!

FOR SALE items posted tothe photo section of this Group

Ken
 

As promised, I have started listing the remaining items that I have related to my aborted attempt to set up a working vacuum coating chamber. This has been a process started at least 25 years ago during which time I have gotten close 3 or 4 times but never quite got it all together.

The items I have posted today are in the "Ken's Pre-Estate Sale" folder. The first 9 photo's are of a NEW (I bought it new) Granville-Phillips Vacuum Controller with manual, cables, connectors, Convectron Tube, and 2 Bayard-Alpert ION Guage tubes. It's never been hooked up other than plugged in to have the photo taken with the digits lit. All items are new/unused and everthing is there to set up a complete vacuum system.

I expect to sell this for no less than $500.00 plus postage to your laboratory. That is about 1/4th of my investment in these items.

I'll wait a week or so to see if there's any interest on the Group at that price then list it all on eBay if not sold here.

More to come...

Re: RGA head substitution

Chris
 

Off the top of my head I would be very cautious in investing money on a RGA/El-control match. Nowadays, RGAs are usually small PC controlled quadrupole mass spectrometers with a mass range of 100 to 300 daltons. I don't have hands-on experience with operating a spetrometer with a different brand electronics.
The working principle of quads are mathematically complex (Mathieu equation)and the control logic is mostly proprietary. The operating parameters for the half dozen or more electrical parameters (AC, DC, RF) are instrument specific and different from one manufacturer to the other; the control algorithms are very complex. This makes a successful match between different mfgrs nearly impossible. Also some of the sensitive electronics is usually mounted on the vacuum unit itself while the power supplies with rest of the data processing electronics is separate. I have a SRS RGA 200 where the entire electronics is integral to the spectrometer. The only connections are an RS232 and 110VAC. The control software runs on W-2000.
Modification to the electronics is difficult and requires that you have all the schematics, the time, the knowledge of mass spectroscopy instrumentation etc.
The best way other than luck in finding the exact electronic controls, is to determine - as you suggested - to find out if an OEM model is sold under different names and then buy the matching unit. You will most likely not get any help from either manufacturer.
Good luck.

Has anyone had any luck substituting one manufacturer's RGA head for

The controller I have is a Spectramass DAQ100/DXM. It has a BNC and a

seems to operate correctly. I've been looking for an RGA head for the
controller for a long time. I see lots of similar controllers up for
sale, but no heads.

OTOH, I see heads for other brands of RGA systems. Has any list member
successfully adapted one of these to work with a Spectramass system?

By any chance did the Spectramass product line get renamed from, or to,
a different brand, perhaps through a merger or acquisition?

Group (and my) status...

Ken
 

Well,

Guess I just had to "Whack" the hornet's nest to get a buzz going.
The Group will remain as long as there's some interest and activity.

I have managed to locate a big box full of goodies, I had mislaid it when I moved back up to Illinois from Amarillo two years ago. I'll make a list and take some photo's this weekend. Right now I'm under the weather after having all my top teeth pulled yesterday. Getting old sure ain't for sissies!

Now that I'm retired, we're considering a move to Costa Rica so I won't be getting my vacuum system together after all these years of collecting stuff. Hopefully I can find someone who will take everything and pick it all up here. That would be the ideal situation as parting it out and shipping to a bunch of locations would be a pain but we'll see what interest there is.

Better go take another pain pill, check back after the weekend for the goodie list.

Thomas,
Are you too busy to continue Group moderation in my absence? I can appoint another to help out if you wish.

Andrew,

Your diffussion pumps has an individual connection pipe to the chamber, or somewhere they join to one pipe which connects to the chamber.

I ask this because I have no possibility to connenct them individually just through one pipe. And underneat somewhere make an Y or T to joint them.
