Close Cell Foam-How to Cut?

Posted By Linton Rohr

Hi Judson.
I like having my larger EP's lie on their side, too.
After tracing the layout lines, I typically cut all the way through the foam with a sharp filet knife. Once you pull out the resulting plug, you can slice it lengthwise, and place it back in the bottom, if you want the cutout to be less deep (I use 2" foam).
I was thinking one might be able to produce a rounded bottom, by sawing with a curved hacksaw blade, or perhaps a semi-submerged hole saw, but I haven't tried this. Could be difficult.
I think I'll just stick with my square cutouts. You can fit a round peg, or EP, in a square hole. wink
I'm getting ready to reconfigure my case, too.
What kind of foam did you get?

Jellies at the Monterey Bay Aquarium

Great shots, Fred. I like them all. Isn't that place great!
I haven't been there for a few years myself.
It's about time for a trip up the coast.

Big Bend National Park

Posted By Linton Rohr

Thanks Bill, those are great shots!
I was able to visit Big Bend in August of '05, and would love to go back.
The scenery is beautiful, and the wide open spaces are liberating.
The night sky is truly stunning. One of the darkest places I've ever been!

Follow up on the Power Supply modification

Posted By Linton Rohr

Cool. You've probably got room for a beverage or two in there too, eh Floyd?
Hehe. Seriously though, let us know how it works out. I predict success! grin

Do I still need a barlow/powermate?

Posted By Linton Rohr

Dennis,
I'll second what Dave said.
I'm thinking about selling my Big Barlow, too, but I want
to be prepared for those rare nights where "the veil is lifted". 8O
The Paracorr would be great if your reflector is a fast f/ratio, say f/5 or less,
but you certainly wouldn't need it for your (f/10?)SCT.
There's always something to "reinvest" the money on though! wink

Discovery- THE FINAL(!) STORY

Posted By Linton Rohr

That's great, John!
I'm glad it's finally on the way.
I received a reply from Bill myself, in response to my earlier attempt at intervening.
I will not post it here, nor attempt to psychoanalyze it.
Suffice to say, you have got results! grin

Here's one for you..

Posted By Linton Rohr

Oh dear. Good luck, John.
I have had two recent transactions where "someone else" did the packaging.
Not a good plan, at all. In one instance, my bino's were bouncing around,
(in a case, at least) inside an oversized box, with no packaging material whatsoever!
That was someone's son. Most likely, someone's dad will work better! wink

router bit - wood tubes

Posted By Linton Rohr

Sounds like you're talking about a bird's mouth joint, Kreig.
You could cut that with a table saw, with a dado blade set at the proper angle.
Or just make two passes with a regular blade.
The angle would have to be pretty accurate to get a good glue joint all the way around.
Here's another method of joinery, where the "angle" isn't so important.

That's great, Jim! Thanks for reporting.
Sounds like you had a very good first light experience.
Congratulations on the scope, the mirror, and getting a couple good nights to try them out! grin
