Just a little update today; I started the preparations for getting some of the parts resin cast.
I made up some MDF boxes with the mitre-saw and nail gun, and embedded the engine and landing gear half way in plasticine.
These will be the first 2 part molds I have made so I'm a bit unsure. But i've VERY (emphasis on VERY) carefully embedded them half way so I can pour the RTV on top and then remove the plasticine to pour the other half. I'll cut breather holes and pouring holes after the RTV is cured.
I was surprised how difficult this process was - its taken me a good couple of hours to get the plasticine smooth and tight to the components ensuring it is in all the detail.
These are the two compionents I'm most worried about, especially the landing gear as it has a few nooks and crannies. The tail plane is smooth and simple so that's OK, and the engine mounts only require a single sided mold.
RTV should be mixed and poured tomorrow, then real life calls, so I'll be unable to do any more until Wednesday next week.
