if any one has been following the duel over spain thread, you know im building a 109D against ted mameres rata, this kit came with vacformed canopies (theres one spare so i have a little leeway) and i could do with advice on painting (before or after its cut out) and the best way to cut it out

Guten Tag Baron!

I see you are everywhere! But you can't escape me! :-)

For the canopy I would make the following:

1 - Mask it first or protect it with masking tape outside AND inside!

2 - Put some Blu-Tac inside to strengthen the canopy.

3- Cut with scissors if you want, but not nearer than 1 cm of the canopy! Some are brittle!

4 - Cut with X-acto knife but leave 1mm on the outline of the canopy.

5 - Dry fit!

6 - Carefully sand the excess away...

7 - Dry fit!

8 - Carefully sand the excess away...

9 - Dry fit!

10 - Carefully sand the excess away...

11 -Dry fit!

12 - Carefully sand the excess away...

13 - Attach with white glue (PVA) and NEVER with Cyanoacrylate or the canopy WILL fog (see below what happened to me with my first vacuformed canopy!)



Hope this helps!

Jean-Luc

P.S. I only do this to have the privilege to destroy your beautiful Messer with me Rata once in the air!

i followed your steps except i used a dremel cutting disc to shave the excess off, and used wood glue to stick it (the stuff in the pic)

Hi Phil

You're a brave man taking a motor tool to a canopy!

But nice job - the fit looks great! BTW... that "wood glue" probably is PVA as Jean-Luc suggested.

As regards using cyano... if you dip a clear part in Future / Klear prior to attaching it, you shouldn't have a problem with fogging. Carnauba wax is also good at preventing this.

All the best

Hi Phil

not that brave, there were two provided so i had a bit of a safety net! and i now have a spare 109 canopy. i forgot to say i did dip it in kleer before it went on, i now have a little more confidence with these, so i can use the replacement canopies on the he 177 kit i have.......
when i eventually work up the bottle to start it!
