Hey I'm finally back with another update! I had to slow things down because I'm back to working 6 days a week, 10-12 hrs a day . Though slow, progress was made on the kit over the last two weeks, focusing solely on the tracks:
As I mentioned earlier, the kit's vinyl tracks are inappropriate for an Ausf.D. These represent the 40cm wide tracks with the sold guide horn and chevron pattern ice cleats that weren't used until the Ausf.H, mid to late production IIRC. It makes sense why Tamiya did this as their old Ausf.H has the same tracks. The Ausf.D tracks should actually be 36cm wide with hollow guide horns and smooth track faces.
Digging around my stash I found some old Model Kasten indy links that I thought might work as a replacement. Here's a comparison photo of the kit tracks and the sprue with various Pz. III/IV track links. Included are the same mid/late Ausf. H links, Ausf, H early 40cm links without the ice cleats and 36cm links that are correct for Ausf.Ds.
But the kit sprockets will not work for the 36cm links as the sprockets are waaay too wide! Scrounging around a Dragon Ausf.D Vorpanzer kit I found that it has an extra set of sprockets (??) so I put one together and compared it to the kit sprocket....big difference!
Checked the Dragon sprocket with the MK 36cm links:
Looks like I had a winner!! UNTIL......I counted the MK 36cm links and realized that there are only about 100 links included with the set!! HUH?? Pz IVs usually had 90-100 links PER SIDE!! DOH!! So the MK links were ruled out along with the Dragon sprocket!
Back to square one! I decided to take a look at that entire set of leftover Dragon Ausf.G Magic Tracks that I used a few for the spares; there are easily enough links for both sides. Here's a look at the links (taped to a piece of wood) compared to the kit tracks:
They're the same width as the kit tracks, but the holes for the sprocket teeth look too small...I'll probably have to modify the sprocket a bit. They have the hollow guide horns, which are a plus. And the raised cleat can be sanded down to make it look more like the 36cm links! OK, NOT perfect, but I think they'll work pretty good in improving the look of the kit.
First step: Sanding down the raised cleats. To do this I laid some double sided tape onto a wood jig I used for T-34 tracks and arranged 10-12 links cleat side up and used a medium grit sanding stick to sand down the cleats.
And after they're done, cleaned up and compared to a MK 36cm link.
Here's the modification I had to make on the kit sprockets. I had to thin out about 10 rows of teeth so that the Dragon Links would fit.
A few links dryfitted onto the modified sprocket and compared to the vinyl tracks. I think its a big improvement! Not only will the track faces look more appropriate, they hollow guide horns are more accurate and I can put some sag on the track runs which I would have a hard time doing with the vinyl tracks!
With my limited bench time, modifying 200 links and the sprockets took an entire week. When ready I used the "doog method" of installing the indy links. For each run I layed down 102 links onto a stretch of double sided tape with a metal ruler to keep the run straight. Then I brushed on Testors liquid cement for the entire run, let it sit for an hour and then gently removed the track run from the tape and wrapped the still pliant track run around the suspension. Balls of tissue paper held the upper run in place and helped form the sag.
Here's how she looks now with the tracks finally done and installed (to be removed before painting)
Yeehaw! Assembly done and now on to the paint booth!
