Steve..... or anyone with RBTG's

Try Wess tabs (cat # 8020)) from Reel 3D...what I do is....

1) Take the black masking side of the mount...in whatever format RBT
4,5,7,W, or F....and put your chips on the white pin bars...but with the
emulsion side up.  In essence you are mounting the image reverse here
(not pseudo though)....but on a light table...you need to have the black
mask....so you can adjust for your window and edges, right?

2) Then ...when you get the chips where you need them...tab them down
with Wess tabs.  Dont worry about the tabs causing any bump or raise in
the surface arae that might affect the focus plane...ever so
insignifigant here

3) Then...take the universal white half that houses the glass...and set
the glass chips in the nesting channeled apertures

4) Take you tabbed chips on the black half and press down on to the
white half with nested glass pieces...snap shut.

5) Do your viewer or projector check...and if you need adjustment...

6) Place mount back down on light table...white side down/black mask
up...and carefully slip your fingernail in on the sides....and run them
down the top or bottom edge...while lifting up a bit....then put a
finger underneath the black half and on to the white half to hold it
down while you gently pivot the black half over and unsnap.  

7) Make you adjustments...reset you tabs (They are removeable)...and
test in a viewer or projector once again.

5) Practice makes perfection...but once you develop a technique for
yourself....this gets very easy...and in fact at NSA in Bellvue this
year...I demonstrated this standing up in the hallways of the
hotel...for someone that had an image improperly mounted.,..and I did a
quick adjust for them...but they had tabbed the image down to the black
halve...so I just handed them the glass halve...while I made my
adjustment...and then we snapped it back shut. (DO NOT TRY THIS AT HOME)

6) For my next trick...I will perform this on the wing of an airplane
while Penn and Teller advise us not to try this.... Paul Wing shoots
hypers off the other wing....call it "triple Winging it!" (Copy of this
went to Paul as well!)
