After a days drying, i reassembled the parts. you can see the green frame. The best way is to stand back and spray the paint on from a distance so it goes on very lightly. it took me two times to get an even coat.

i tested the Roco wheels on the Faller front axel. the on/off switch is in the foreground, the GWS Pico Servo is on the left. The beginings of my brass frame are on the right

i trimmed the mounting arms off the pico servo so it will fit in the bed snuggly. using a dremel with an odd short tip drill bit, i carefully cut a hole almost perfectly for the servo to come through the bed. definatley wear glasses while using the dremel

to make a back cover, i trimmed a sheet of copper to fit in the back opening and bent an angle to hold itself and eventually be connected to the chassis and frame. i then cut a hole for the faller on/off switch and took it outside to paint. i filed down the platic switch and painted it at the same time. fits like a glove! i haven't decided how to secure it to the copper sheet. i might use two micro brass screws

now inside the bed, of course it fits well. almost too well as it's difficult to get in and out without scraping the paint. the end result! i know the faller on/off switch is a big one, but i think i did a good job of blending it in.

i finished making the frame peices. the bent frame rail is to provide the steering servo clearance to fit and operate. i used 3/32x3/16 brass rectangel tube which is just slightly deeped than the frame on the roco minitank. i used an exacto metal saw and mitre box to cut the peices, pliers to bend the one rail and a dremel for grinding and polishing. i used the wrong soldering iron (low watt iron for electronics) and it took a long time to get it right. use a high watt iron.

i carefully cut away pieces from the stock frame and painted them. the front frame piece will be used to screw to the frame and snap the front cab to. it will still be removeable as it was originally. the small pieces including the tow hook (i plan on getting a trailer) are for detail.

these are practically all my components needed. it's taking longer than i wanted but it's coming together. i use a 12"x12"x1/4" stone sample (marble i think) from the office as my work surface to prevent myself from burning, cutting or otherwise damaging the table.

i used 1/8x1/8 brass tube for the rear axel mounts. i dremeled out a little over an 1/8 on each side, bent down one side. i will either solder them on tho the frame or drill screw holes and screw them on. i'm leaning toward screwing them on so the rear axel will be serviceable

using my dremel, i cut out the space for motor and spur gear in the bed. i double checked to make sure everything fits well. a tip i learned early in my career, measure twice-cut once

i drilled holes in the frame and axel moounts to mount the axel mounts and body to the frame. i'm using size 90 x 3/8" brass machine screws and nuts, my lhs was out of washers, which i will have to go back for. this is a simple arrangement without using bearings and other performance enhancemet peices. i'll try to incorporate those in the next project

What are you going to do to the body? I think it looked better green, but if you are going to put decals on it, that would be cool too.
