Getting closer and closer. Still needs some cleaning of the side tables. Might need advice on how to get them clean. Perhaps if I had a big enough container to immerse them in bleach for an hour or so.
Today, I changed out all four wheels. The small ones are new and they lock, which is a nice feature. Had no problem pulling off the large wheels. Started with application of a bit of heat from a heat gun but ultimately found that it wasn't necessary. Pulled off a bunch of wheels today. From the Platinum, from the 1000 frame I'm breaking down (bit by bit with the help of PBBlast), from one of the grills we picked up the other day. Wanted old style wheels that were in good shape as a starting point.
Here's the Platinum up on a block with the old wheels off:

Bucket just large enough for one wheel at a time:
Here they are after soaking for about 30 minutes. Still a bit discolored.
Wound up putting them back in for another half hour. The final result was great.
Today, the new drip tray and grease catcher arrived.
Here I'm holding it on its side. Look at how nicely the whole thing holds together. You experienced fellas have no doubt seen this before. For me, it was a nice surprise.
Here's the new tray pushed in part way.
And here's the grill with the new tray, new small locking wheels and the bleached old-fashioned large wheels.
I have a cover for the tank, thanks as always to a suggestion made here. Just a bit of cleaning left to do and then the tank cover.
Samuel is sending me a set of complimentary burn tubes so I'll probably install them too.
Getting really close. Suggestions on how to clean a bit of rust off the stainless frame and on getting the side trays looking like new would be appreciated. Thanks.
