Nice one, I do a similar thing but different if you know what I mean

I start off by mounting two 12" pieces of wood to my desk leaving the track width between them, the wood is to keep the tracks straight while im building them.
I place a about 50 pieces of track between the wood blocks and when they are all lined up I put dabs of glue on the joints and allow about 15 mins for the glue to set.
After this time the glue is set on the inside of the track (where the dabs of glue were) but the tracks are still flexible enough to place on the tank and form round the drive sprockets and allow for track sag.
The first run goes half along the bottom wheels around the bottom drive sprocket and part way along the top of the wheels (allowing for sag on a tiger Panther etc).
I then make another length of track up and put this one over the rear drive sprocket and shape in to fit the first part of track but I DONT glue the two halves together.
When they are set you can remove them from the tank so you have the pre-shaped tracks already for painting and weathering and once the model is painted you can put the tracks back on the model and using a small amount of glue join the two halves together......like I said ....similar but different
