Staring to get over this bug finally, not there yet but feeling a lil better as each day goes by. Got some castings from CR last week and in there was another set of the domed parts that go on the throat box. One was pretty bad with some air bubbles but the main reason was i messed up my first pair trying to add some more curvature to them. They became test subjects for this new pair. So why try and add more curvature? As far as i know and thats going by the maps the parts should be Wostok parts. The part's from CR were created for there Atlantia build and infact i was told i would need to trim a small amout off there diameter to fit the Galactica build. Well when looking at them they appear to be pretty flat with very little curvature to them at all. So this got me thinking on what i could do to make em look a little closer to the Wostok part i came up with an idea but but didn't do a great job with the original ones. As i said they became test pieces in the end.
So here are the castings as they come from CR. Pretty flat as you can see..
I marked out the chips with pencil before sanding them off so i could try and press the casting between two Wostok parts. I learnt with the first pair the chips would need to be removed to do this as the surface needed to be one level or distortion to the casting occurs. So sanded em off and then went ahead and dipped the casting in boiled water for a bit to sofetn. After a minute i placed it between the two Wostok parts and pressed them together using a clamp.
After running under some cold water i released the clamp and the outcome was pretty pleasing. About as good as i could hope for anyway.
Then i reaplied the chips going on the markings i had done previously. Not too bad untill i noticed looking at the reference later that some of the chips were out of position on the castings compared to the original. Not enough to bug me and left em as they are.
Finally it was getting em onto the throat box. I actually have one oriented slightly out but again it's not emough to bug me right now. Slapped the other bits together along with some more chippen and this is the outcome. Throat box is still just sitting in place so may be out of position by a whisker and theres a good chance it may be that way when it comes to glueing it the way i do things..LOL
