I stole the idea for this thread from the Classics forum...  They have a similar one tat has been going for a month. Please post if you did anything ATM.  Did you find a part? Work on something tricky? Use a new technique?  Here is a spot to share your idea when a starting a fresh thread would be too much work.

I'll start!  Today I combed Ebay for star nuts, thumb screws and found some great industrial lazy susan bearings which might make for a good start on some rotating rings See here:

Yesterday was better, I found a bag of 10 miniature ball bearings for $3.00 that I can use for Crayford focusers, and I measured some Schott glass blanks I have.

I did a little work on drawings for a 10" ultralight truss-style rich-field Newtonian.  Hope I someday find time to start building it...

Printed a holographic plate that kingjames posted a thread about a couple  days ago to test a 8" f4.475 -1conic.

Today I cut a piece of plywood to size and laid out a mirror cell triangle on it , tomorrow if all goes well, I'll try cutting it out.

Last night my glued 10" mirror finally came un-glued after 20 years so today I bought some silicone glue and am waiting for it to set.

Continue to drill holes & hunt for hardware to complete my $23 EAA camera (check the EAA forum for the buzz).

I was grinding a small mirror blanks. (3~5 inch)
For miniature replica cassegrain telescopes.(    pretty fun )

^{Today I did a bit of CAD work designing my Ultralight 12.5" F/4.3 dob. I'm getting really happy with how the analysis of load and deflection is coming out! This will be an Ultralight, but it WILL manage the close tolerances required for collimation of a faster dob with Parracorr .}

 

^{It will be awhile before I build it.  I'm still designing at least two projects ahead of my builds--which are seriously getting slowed down by -5 degree F weather!}

Mount for 20x80 Binoculars or small refractor.

Like a TV but add slow mo.

I'm rebuilding my old 10" solid tube Dob into a more easily transported truss type.  Here's the mirror cell, ready for priming and painting.  This took me part of three days to get to this point.

With the onset of super cold weather, snow and ice, I took the time to complete my hypertune while I wait for my belt drive conversion kit.  Next up while waiting is to disassemble and regrease the motors, then finish hacking up my Moonlite to finish my focuser build.

some detective work on the hc <-> mount comms for hdx110

[Alex Parker]

Three hours of testing hypotheses about why the collimation shifts on my dob as I move it away from zenith.  Found a lot of things are AREN'T the cause...

[pbunn]

Drilled and tapped some holes on my camera bar to allow me to mount a Rigel Sight next to the optical finder. The bar has a DSLP mount, an optical  8 x 50 mm finder, a dovetail holder for my ST80 and now the sight.

 

Did some more research on the MyT and bought an adapter to mount either a MyT or an AP Mach 1 to my Losmandy tripods.

 

Too cloudy to do much else.

Turned a lens cell on the new lathe. It put a big smile on my face.

 

  And I worked on the bluetooth adapter to allow skysafari to communicate with the  Minitower.

 

Lastly set up a new (upgraded) computer to use with the 3D printer.

I bought some vintage wood cases and spent the morning clearing out the interiors. Tonight I'll sand them and get them ready for fresh stain and some poly!

[brave_ulysses]

pics or it didn't happen!

 

good thread, mr cunneen

An award on my first post?  What an honor!  This must be in the "no such thing as bad press" category. 

 

I know John, it's cruder than crude.  You're not even seeing the pile of cardboard strips I've been through, and I removed the taped-on meter stick I was using to rough gauge element spacing and eyepiece distance.  Thanks for the reply.  Very friendly people here.

All the best,

Follow up with the stenciling and lights installed, with meteorites.
