Next step. Since I intend to use the gun for more figures I decided to try to make a copy of it using a putty mould. This is a method I\'ve only used for one sided parts up till now so this was an experiment.
Left to right, up, then down. When I say talc this can be dusting with talcum powder or smearing with vaseline/lipbalm. Haven\'t yet figured out what works best.
- Talc flat surface and flatten a blob of putty on it. Talc the original.
- Press in the original. Make some holes as mould guides.
- Let cure, talc mould + original. Flatten another blob of putty and press it over the mouldhalf+original you already have.
- Let cure, remove original, talc the mould halves (whole inner surface of the mould, not just the cavity), add some putty.
- Press mould halves together and let the putty cure.
- Done. Remove copy (note, this is a new mould since the first one was damaged - hence the \"mirror image\" compared to the other pics) andclean up.
- Original, copy from mould, cleaned copy (barrel will be added in brass. Ugh, just noticed I need to rework the cartridge as well).
This was my first attempt and I think the method works ok for a two part mould but I will have to experiment to optimise the process. Main problem was that the copy tended to stick to the mould, especially if the mould was damaged. That\'s how the mould was damaged in the first attempt. It\'s a fairly fast way of making copies, especially if you can use a putty oven. Copies were far from perfect but good enough to use after some cleaning. Surface was uneven and this could be because of the talcum powder (either directly or because of enclosed air while curing in the oven. Things to try:
-Effect of normal opposed to oven curing.
-Material of the copy (I used a Milliput fine/green stuff mix).
-Moment of removing the copy (seemed to work best when not fully cured).
-Mould release agent (talcum powder/grease).
