Thanks for the comments guys
Kent,
You always amaze me with the quality of your research,
I will be doing the early 211 and as such have now filled in the water drain slots in the coupola (The Photobucket site is down at the moment so i will post a updated shot when it is back on line). I have also filled the holes for the Pilze (2 ton crane) as these were not fitted to this tank.
Dale,
My work bench is on wheels, so when i want to get the Tiger down i move it to were there is a bit more room and drive down my car ramps ( just got to remember to chock the wheels and have a good heavy tool cabinet on the bottom of the work bench to stop it overballancing

).
The turret roof is standard with the late Tigers, i had to use my dremmel a bit on the loaders hatch cut out to make it fit the Armorpax hatch.
Brown,
I used Milliput for the Zim (lots and lots of packets), Milliput is a 2 part putty that when mixed is workable for about 1 hour and sets in 2 to 3 hours, Not sure if its available in the USA but there must be a equivalent.
To apply the Milliput i mix up a lump about the size of a golf ball and roll it out between sheets of grease proof paper to about 2mm thick, place the sheets of milliput onto the tank and press into place, It can get a bit sticky so spray a bit of water on it. The patter is made with a tool i formed from some scrap steel (It looks a bit like a small spade). to form the pattern i just press the tool into the Milliput to form verticle coloums.
Word of warning:- Applying Zim will drive you mad, it takes ages.
Regards
Steve
