Allright folks, here´s an update: probably because of the extensive paintjob I have given this rubber blaster, the T-tracks - which are part of the mold so it´s all one piece - became tacky and seem to "melt", so for all of you getting one of these bad boys, consider thoroughly if you want to paint it.
I decided to cut them off and replace them with some black plastic tracks, so I cut them off using my trusty exacto blade... aaaand cut myself.
put a band aid on it and continued:
As you can see, I have decided to go for the "Move along"-layout of tracks (above the rubber bapty you can see my SWAT-level DD Bapty with the same tracks-layout) and drilled holes accordingly.
I then used some black plastic T-tracks from Super6 Props, cut them to shape and used my heatgun to bend them.
Here´s what the original screen-used prop looks like:
And here is what my finished blaster looks like (the Sheartech blaster is the one at the bottom, DD at the top)
And finally a pic showing it with some other project I´m working on atm.
Oh yeah, and I can definitely say that I prefer working on Sandtrooper lids...
