getting 12"-18" of snow today - 3 feet drifts in my driveway
at present. Going nowhere :) for awhile.
Got bored and made a few updates to projects.
Here is a small update I made to the A4 railway Launcher.

I added the forward cradle/saddle and repositioned
the aft saddle to where it goes.

Regards

Hi, I was going to do a test print of the launcher frame in 1/72nd scale
just so I didn't have to chop up the frame. I wanted to see what it looks
like in one piece to figure out better on how to approach the platforms.
But, at the last minute I decided to go 1/35th scale. Attached are few pics
showing the print as it just finished and after doing a first wash in alcohol.
Just a little warpage but that should resolve itself as parts dry.

Materials:
14.28 ml of resin for the basic parts (~ $2.12)
28.72 ml of resin for base and supports ( ~$4.28)

Total build/print time was 5hr 42 minutes

Regards

Just a quick pic of the basic frame parts removed from supports.
I added a few side-to-side, cylindrical supports (seen in pic) for
printing just to reduce any warping and twisting etc - those will
just be cut off once the parts are assembled together.

Hi - basic frame partially assembled. Had to use a little squadron putty to
fill in some very slight gaps and still needs some sanding etc but the basic
frame ends came together well and the overall geometries are pretty straight.

Looks very good Greg :thumbsup:
Do You use cyanoacrylate glue?
Does this 3D resin behave different then other resins used in limited editions kits from companies like Aires, CMK, Verlinden?

Hi - yes, I mainly use super glue (cyanoacrylate)
for this material. When its dry, the super glue acts
almost instantly. The material is quite different from
traditional model resins though. Its a bit softer for a
time after being printed and it can usually be cut easier
(like if you need to use an xacto knife to alter its shape etc).

Note - you can also use standard testor's modeling glue in
some cases (after its thoroughly dry). It seems to work quite well.
Not sure how these glues continue to hold up over time though.
I have used it in areas that I thought needed greater strength and
it seems to work just like standard plastic.

Regards
