Reproduction in resin OOP parts in 1/72

[63cpe]

Hi 'y all,

I'm getting quite enthusiastic about reproducing modelling parts in resin. I did earlier double airliner (1930-IRS/40-IRS era) seats on one strip of six, jet exhausts, jet turbine faces and the Aero a-100 engine (Hispano 12N) and some wheels. Now I'm doing an other set of reproductions. This time again some turbine faces, exhausts but also complete engine nacelles like: single Junkers Jumo 004 (Me 262 engine nacelle), double BMW 003a (Ar-234C double engine nacelle), 1/100 Sapphire ASSa 7 (from Revell Victor), Fw 190 engine front without cooling fan, Fw190 cockpit tub and a range of single seats and luxurious benches (from Cessna 172/O-2 and a three seater from an OH-13). See pictures.

...Anyone interested in repro resin parts?

Always good to have alternative engine source without stealing from an otherwise complete kit.

Lockheed Viking and Warthog strike me as having engines which would be nice to have a source of in resin.

Depending on the rubber used, I'd advise against lego for the mould box - the rubber can have a distressing tendency to leak through the gaps.

From experience, I agree wholeheartedly.

I'd keep an eye on the plastic tubs that you'd generally throw away - yogurt pots, margerine tubs, etc.  You'd normally dump them in teh recycling, but here's a further use.  One type I just spotted was the catering marge pots - the two/three portion ones that you get in hotels/cafes?  Ideal for tiny one off moulds.


The plastic seems to be the same as kit parts too, so it you run out of plastic card, dump the marge into something else and use the lid!

I disagree.

I use Lego to make the mould boxes too, I stuff the insides of the bricks with modeling clay, if you put in a tad more than needed it seals the gaps between the bricks when you press them together. I then smear a bit of clay into the vertical corners, I haven't had a leak since I started doing that.
Seeing as I use the bricks again and again, I don't clean the clay out of the bricks, just collect what I've put in the corners and reuse it.
If you have to make a mould box where the bricks aren't long enough, smear some clay on the end of one brick before you press in the next brick.

I also tried Lego bricks but got leaks.

I just make up boxes from scratch sheet styrene, thus I can make them any size I like to minimize the amount of RTV mold material which gets expensive.  I just use super glue or a hot glue gun on the seams of the box, then glue the box to another sheet for the bottom of the box.  Then pour away.   

Here are the boxes for my 2 part mold Pegasus Engine and simple one-piece molds of an aft nacelle for my Lift jet C-130, and a one-piece mold for an F-102 radome.

Very nice David, I  would be interested in some  engine pods  for future  projects, as I want to  kit/scratch  bash something using a  1/144th Concorde  and put some  big engine  pods in the wings similar to the  Bristol  T.188

OK, I don't have complete nacelles like the Bristol 188....yet...But PM whenplans get more serious.

Nice one  David.  The shape  of those kind of  engine pods is nothing  majorly technical, but still beyond me to get  them to look right.
