I have dabbled a little in resin casting, mainly making my own resin pen blanks, but I have been thinking of purchasing a pressure pot to remove the bubbles in the casting.
Pressure pots are quite expensive so I have been looking at what else I can use it for.

It suddenly occurred to me that I can incorporate resin in my toy making, and this is my first attempt.

I decided to make the “four quick and easy planes” plan set.

I started to make the helicopter, and cut out the main body, I cut out the windows and will replace with resin ones. The pictures show me taping the windows on one side of the helicopter.

I wasn’t sure if the tape would hold the resin in, so I clamped the body to a solid board.

I start by mixing the resin and add a tiny amount of blue to give the impression of glass. The pictures show the type of resin, and colour I use.

After I add the catalyst, I stir thoroughly and after a short time the resin will thicken, I can then pour and leave to set.

This is where I am now, I am so please that there was no leakage even thoughI just used tape to seal the windows. I am not surprised to see the bubbles, as far as I am aware I will need to purchase a pressure pot to eliminate these. My next task is to sand flat and go through all the different grits to get a clear resin.

I have seen a guy over here in Oz using a modified Pressure Cooker as a vessel he puts smaller items in to minimise bubbles during curing. He pressurises via a threaded section in the modified top where the weight would normally fit.

Not my current project as I am looking to vacuum forming small windows (white-walling for tyres etc) and the like.

I realise you would be limited by the size of the pot but is assumedly DOES work!!

I have seen on the internet people using a paint pot from Harbour Freight as a pressure pot. They do have to make a few modifications to this, you might want to check that idea out

Thanks for the suggestions, I have been researching the pain pot idea, as they do come up a lot cheaper.

this looks to be a good idea - I often struggle to know what colour paint to use for windows- this would solve the problem

This is as good as I can get the windows, I went through the grits and then the micro mesh, but unfortunately I can’t get it any clearer.
I am going to order a pressure pot next month which will eliminate the bubbles, also I think that the resin was going off. I like the slight blue tint on the windows, I will continue with this idea, All your comments are greatly appreciated.

Google polishing resin will get you lots o hits on how to get it clear. It's basically highly polished. You might not be able to do it in this case because it is in the wood.
