It lives! This army isn't dead, it was just resting. It was put on something of a back-burner while I worked on my Chaos Marines, but they're all done now. There was also something of a delay while I waited for an order from GW. Along with a couple of Reaver Titans, I'd ordered some spare 40mm round bases, which were out of stock and meant that it took over three weeks for the order to be dispatched. It's arrived now, though, so I can resume this project just in time to get it back on schedule.
So the next unit in this army is a standard-configuration Warlord Titan:

When I got this model the card disc from the base was missing, so I fashioned a replacement out of some plasticard. The small gun turrets on the back are lance batteries from BFG ships. I'd have liked to have stuck with purely old-school parts, but I didn't like the holes in the back of the carapace and didn't have enough banner poles to fill them all (and wasn't that keen on them anyway) so I decided to make an exception here.
This model was all finished and painted a week or two ago, except for the Turbo-lasers, which I didn't have until I took them from one of the Reavers that arrived yesterday. I had been going to replace them with a pair of Quake Cannons that I scratch-built a couple of weeks back, but on getting the model I discovered that they were far too big. Consequently I've assembled that Reaver with a Volcano Cannon and Gatling Blaster instead, and the QC-equipped Reaver will have to wait until I can find some suitable weapons.
Coming next will be a standard-configuration Reaver Titan, which will bring my total for this month up to 1500 points. I've decided to revise my previous schedule, since 500-1000 points a month seemed a bit feeble in an AMTL army. The new plan is this:
August: 2 x Warhounds (550 individually or 500 as a pair) - DONE
September: Warlord (850), Reaver (650) - (1500)
October: Reaver (675), Warhound (275), Forge Knights (400) - (1350)
November: Reaver (725), Warhound (275), Thunderbolts (150) - (1150)
December: Warlord (800), Forge Knights (400) - (1200)
It remains to be seen when Forge World will have their Thunderbolts back in stock, so there may be some revision to this schedule yet. Also, I'm still not completely certain about the weapons on that second Warlord. I'm currently thinking of going for a cheap(-ish) combination of two Gatling Blasters, an Apocalypse Rocket Launcher and a Laser Burner, but is that likely to be any good? The other combo I was considering was a Laser Blaster, Gatling Blaster, Turbolaser and Support Missile for 900 points, but that's a pretty expensive Titan and I'm not certain whether or not it's worth it.
