Clear Canopy issues and possible solutions

[paul1598419]

Is it 116.6 degrees because that is what you made it to be, or could it not be 180 degrees with the optics on a ledge down the center of the aluminum tube? If so, then this idea could work...... at least it seems so. Having such a small flat glass window doesn't look as nice as 180 degrees of visual access, but I guess if the flat window is easier, then it is your build.

Sorry...we do not have enough lateral room to accomplish a " slide up/slide down " cover....must be a rotating construct.

CDBEAM :undecided:

Ok, well back to the drawing board.

 

[Alaskan]

can the cover be a cylinder which slides forward out of the way instead of turning it with a slot in it?

Or maybe a cylinder that's removable?? :thinking:

It's your build Alaskan, just trying to help brain storm.

Well.....with the Cyan Cannon build....we really have no room to put the optics down in a channel....so...they must stay on the flat bridge....which equates to 116.6 degree.

I propose we use a dual tube design....a " Tube in a Tube " concept.

A Main tube machined from Aluminum....with a 116.6 degree slot removed...full length.

Then use an Acrylic tube, same length, thickness and OD/ID. Machine out a chord of 116.6 degree.

The Acrylic section will then be epoxy fixed....into the Aluminum section.

When the degree angles are done correctly....the Acrylic section is " inlayed " into the Aluminum Main tube.....and we have dual construct ....with the same OD and ID.

See the attached drawing. Gort Shroud TIT V1.

Because the openings are beveled/angled...the fit....will be like a keystone geometry. The Acrylic will drop down...so far...and stop. Likely a very thin application of clear epoxy will fix the Acrylic to the Main tube !!!:eg::eg:

The end result will provide a Field Of View (FOV) of 116.6 degree. Not the Full 180....but much improved over the 48.8 degree of the flat glass plate design.

I have a method figured out on how to machine the tube sections. There may be some...er..ahhh..waste pcs as we "transverse the Learning Curve" !!! So it goes !!

Stay tuned as this continues to unfold....for we are again in " Undiscovered Country "

I like it. But, please don't take my questions and suggestions as criticisms. I am just trying to understand what you are doing.

:crackup::crackup::crackup::crackup: Oh Yea....see what Zippy sez about this !!!

Actually....Paul....your thinking got me motivated to figure out how to have a bigger window.....in a word............Synergy !! ......................all of us.......Brain Storming...Thanx !

As to the machining complexity...the TIT design will be more straight forward machining......and delver a 116.6 FOV !!

As I mentioned....the challenge is figuring out a method....on how to hold the work piece's...to machine the slot and companion piece in a tube material....took me thinking on and off during today....but...I now have a plan !!!

Well, Some of you know how I prefer to CAD all details out.

This discipline is especially important....when you only have one shot
at getting a location right in a build. It is very disappointing to drill a location bore wrong....in a work piece you have many, many man hours invested in. Typically, even if a re-bore is possible...it is not hidden...and looks bad !....and I find...not to my standard !!

So....to that end....I CAD things out....and even then...sometimes screw it up !!

See the attached drawing on the Gort Shroud TIT rotation projection. The Rotation Stop/Bolt must be located either aft or forward ...and not in the bridge/flat section. The Optimal location is shown in the drawing.

And...a corresponding transverse slot must be machined into the Aluminum portion of the Gort Shroud.

This detail is in preparation for final work on the Cyan Cannon Build, as the CC will use the Gort TIT design.

We march forward !!

Thanx....and " Zippy " sez thanx too !! :crackup:

It's going to be one beautiful build when you get finished with it. Looking forward to seeing the end product. Alaskan is going to have a build for the record books, so awesome. :drool: Best wishes

CD, there are never any waste pieces, only pieces to be used for another project. :crackup:
Honestly though, if you're not making a few "tryout" pieces, you're not doing anything.

This canopy design is shaping up nicely, it's going to be a slick addition to this build!

Your tube in tube designation is perfect, can't go wrong with TIT!

 

[paul1598419]

I am looking forward to this build with baited breath. :crackup: It is looking great, so far.

 

[CE5]

can't go wrong with TIT!

Was Gort, male? female? or gender neutral? yeah, TIT is way better than MOOB- manually operated orifice baffle.

Gort...was the strong and silent type....as to gender....:undecided: Switch Hitter ??? :crackup: Gort was just a " Bad Ass " :eg:

As to the nomenclature...for " Tube in a Tube "...TIT....Just a coincidence !!!
Sometimes....the Universe hands you these random acts.....and...ya just gotta deal with it ! :beer::beer:

BT....Regarding " waste pcs "....I gotta pile of'em !! but They are always; 0.5 mm too short, 0.5 mm to small dia...or 0.25mm too thin !! Hmmm....Karma....for me being such an ____ ____ !! :crackup::crackup: Whatever !!

Paul....Thanx...The finish line is in sight...No More Changes !! :eg:

And...lessons earned on the CC build....will be applied to several future builds !! :yh:

So it goes !

BTY...Wadda think of my new Avatar ??? Catchy...idden it ??? Gort has the social skill set...I aspire too !!!! #1 Gortism: I do not like what you are doing....so....I incinerate yo Happy Ass !! Wadda Bad Boy !!

I'd swear that's from an old B movie. Can't remember which one, but nice find. :yh:
