Well I have had a brown box sitting around for a while, been busy with other projects and costumes, now it's about time to start on my hero bucket which will be the last of my hero conversion. This is an ATA helmet which I have decided to modify to a hero 3 teeth per side version, a TM is being saved for as we speak
I started by using my hobby heat iron to apply heat on the inside of the lid on the teeth that needed to be removed, gently moving the iron around while keeping a flat piece of triangle of plastic held tight on the other side, took a bit of time as I didn't want the teeth to completely melt through. This worked well but left a very small ridge around what had been pushed through so I spent some time with 240 grit sandpaper to remove the ridges, then went to 600 grit and on to 1200 grit. Once the sanding was finished I buffed with some cutting compound and it came up a treat.
Sorry no photos of the teeth at this stage as I go a bit ahead of myself and went right on to sanding the inside, drying off, masking up then a couple of coats of satin black.
