I was able to make it harder to open the air intakes by doing the sponson first. Should have opened the holes first. Anyway, the screens for the Tamiya kit are the same width, but about a millimeter shorter in length. Looks like I can make it work.
The seams are sealed, sanded, and textured (with super glue and cornstarch slurry dabbed on with a bamboo skewer). I use silver paint to help me see any gaps.
I cut strips from sheet styrene to extend the holding straps to the brackets. Super glue, with a little corn starch, filled the gap. Then all was sanded smooth.
Even though the tracks are glued and dry, a little heat from a hair dryer softens the bond. Very carefully, the tracks can be threaded onto the vehicle.
The sprockets have to be constructed so they can spin freely, or this method would be very difficult. The rest of the wheels have been glued in place, but if they could turn, it wouldn't hurt.
In a few minutes, the glue bond tightens, and you're done! I started with 89 links per side, but after wrapping around, and sagging the track, the connection point was at 83 links. I always try to connect on the bottom.
I don't think you could use this method if the lower hull wasn't modified (raised), like I did at the beginning of this project. There would be too little clearance to thread things through!
