Arm

I don't think you can avoid modifying the arms of the HGUC GM Quel. The lower arms are scratch build from plastic cards. The tricky part is to incorporate the elbow joint into the arm. Stacks of three 0.4mm styrene cards form the side wall of the lower arm. Holes are drilled through the stack to place the polycap for the elbow joint follow by puttying. Same thing was done in the middle of the arm for a polycap that will attach to the shield. I trimmed off the flare of the hand socket to decrease the size and epoxy puttied it into the other end of the lower arm. A hallowed out Kotobukya rectangular nozzle is used as the sleeve. I also used some think styrene sheet to detailed the elbow joint cover.



The lower arm is cramped with polycaps, some planning with drawings is needed to make sure there is enough space. With some luck, pretty good mobility can be achieved without too many trial and error. A final thin styrene sheet is used to add the surface detail (notches) on the side of the lower arm.



You may notice the bolt of the elbow is attached to the upper arm, instead of the lower arm as in the stock kit. You can saw off the bolt carefully using a saw scriber and glued onto the upper arm with the elbow joints locked in the upper arm. This is not the best arrangement since the entire arm are now in one piece and need extensive masking for painting.

One advise I have is not to go crazy when beveling with the sand stick. Care must be taken to check the surface after several sanding strokes. Or else you may have to putty and resand like I did here.
