Halo Reach M45 tactical shotgun - The Molding and casting process (PIC HEAVY)

It would probably help if you attached handles onto the MDF support boards, that way, it'd be easier to help you rotate it/hold onto it if you continue to slush them by hand, at least for the heaviest molds
 
I never fail to be impressed by not only the talent of the people on this forum, but also their willingness to spend the extra time and effort to teach others.

Great build Streetrocks!
 
I know it has been a while since I had a chance to post here, but I happily have progress to report! I completed the pump mood and after finally working out most of the kinks in the various molds we now have this:

The first shows all of the individual parts, while the second shows its mostly assembled ( I left out the trigger and the housing on purpose). The entire thing is very light, roughly 5 lbs, and it is very well balanced. It is cast in smooth cast 65d, and feather lite. Most of the pieces are so light they will float in water.

I will be posting up a junk yard thread shortly
 
Is there still an interest thread for this?

I have a for sale thread going in the junkyard at the moment. You can also pm me.

Had some requests for closer shots. Here are all of the parts close up with flaws or seems pointed out. As far as bubbles and seam lines, I try and take care of most of them before I send out the parts. The biggest problem areas for bubbles are the hex nut details, though I should be able to mitigate most of those with future pulls (I've been in the process of tweaking my casting methods for each particular mold). The majority of the seam lines I tried to keep inside the parts, or in areas that were unseen. There were some small flaws in the pump and stock molds, issues between the print layer and subsequent layers, though most are easily fixed with very minor sanding. Here are the pictures (it's about to get a bit pic heavy):

Small bits: only a few very minor bubbles, and the seem lines are in unseen portions, and easy to clean up:

Upper receiver/rail: extremely small bubbles in the rails, some bubbles in the hex nut details. These should be mostly eliminated in your casting

Barrel assembly. Very very minor seem lines, few bubbles in the small screw details, once again, should be fixed in your pulls

Pump: some bubbles, one seem line at the back, and some surface imperfections on the grip. Easily sanded/filled, I used a small wood chisel on the larger bubbles of resin
