Re: Mixed Pep/Foam War Machine and Gatling Gun with Stronger Mount and other WM weapo
Thanks for the eBay tip made007!
I was just trying to figure out how I was going to fiberglass that little shoulder pod and make it firm enough to accept Bondo and sanding ect...
I was going to basically fill it with Bondo resin, but thought, "HEY! I haver a case of 320 and 321 smoothcast.:lol
So I turned it over and poured in 1oz od 320 as that is a 10 minute set up, rotated it around to evenly coat the interior...then did another 1oz before it hardened...
It worked out awesome!! :thumbsup The piece is as hard as fiberglass and just made my job simpler by far!
Just to show you how strong it turned out! This is one coat resin outside and smoothcast inside...
Plus it sands and is plenty strong for Bondo!
Soooo, Since that went well I decided to risk a shoulder bell for an experiment since they build fast...comparatively. *sigh*
Prepped edges with tape
Promptly poured in 6oz of 320 and rolled it around to form a skin.
Have to watch how tight you tape it...it sets up faster than 10 min but is very liquidy for the first 2-3 min
ended up with this,
I had to go back and do each side of the bell individually as not enough material stuck to the sides and it was too thin and floppy.
So in all it went well, but learned;
.use small amounts, the larger the batch the hotter it gets and the faster it cures. Almost messed up as it all started to thicken on one side of the bell mid rotation.:confused
.DO-NOT STICK ANYTHING IN THE HARDENING 320!!! Not a gloved finger, a popsickle stick or paint brush... when it goes OFF and starts to turn white it is incredibly sticky!!! It will stick to the object and pull it completely out of the area you are covering! Don't ask how I know and I wont tell. :confused
:$
. plan on doing it in sections that you can keep the dependant areas or lower parts evenly covered rather than expecting to coat the whole piece. That wont work. Here, on a piece like this, doing it in 3 sections would work really well. middle x 1 than sides x2.
.make sure your tape is very secure as big leaks = BIG messes that have to be fixed:angry
I.E. 30 min with dremel/covered in plastic dust/with respirator in 100 degree heat.:cry
. de-mask edges for clean-up once 320 goes all white.. it is still soft enough to clean up with an X-acto knife.
. For larger pieces, gonna use the 321 with 30 min set time.... more to report on how that goes later.
