Hi Folks,

lot of details crafted, not much to see but also a lot of time consuming work.

Hi Folks,

small Update, tested some welding seams, partly very rough and hard to copy on the original 331.

Hi Sascha,

How long will it take for the welding seam—— I reckon it was made by epoxy putty—— to dry? After that, does it shrink?
I have used one kind of the car body filler on other models, which took very long time to dry, and get shrank.

Hi, I used Miliput for the seams. There is no shrink at all, it is the Standard Miliput, you have round about 10 to 15 min for texturing. I think the filler you use (Polyester?) is only for very thin layers.

Hi Folks,

small Weekend-Update. I filled (UHU Endfest 300 with cotton flakes) the gap between the side armor and rooftop. I´am not sure if all JT do not have this gap, but 331 definitely not. Also new is the Persicope/Scherenfernrohr hatch. I made a new one, because measurements (hatch size) and screw holes differents from the original and blueprints. The edges of the rooftop are sharp now, I used some aluminium triangles and attached it also with UHU Endfest (hardened 75°C).

regards

Hi Folks,

some news about the JT 331. First thing is the new comanders hatch, I decited to rebuild it because it was easyer to build a new one for me. Next detail is the liftingeye for the "Saukopf", the AT thing is much too small. The Saukopf himself got some cast markings, but I am not realy sure about the "aKn". My pics from the Aberdeen 331 are very rare of this section. If someone have better resolution pics of that area, please PM me!

Hi Folks,

today some news from the gun elevation. I use a RB-35 gearmotor to drive a threaded bar. The stopswiches are missing yet. For the gun recoil I will use a high torque servo. I do not reach the complete 140mm recoil way because this is too much effort to fit the barrel mount ( extend mount and barrel and so on). The max. recoilway will be 50mm, wich is ok as compromise.

With the threadbar I hope to reduce the clearance to zero, for a very stable gun without wobbling while driving. Because of this the threadbar is in the center of the gun and supported by a spring to balance the extreme long barrel. If it works I will see soon... :mrgreen:

regards

Hi Sascha,

50 mm recoil length IMHO will hardly fit a Jagdtiger, because the huge recoil was like a trademark for this gun. Is there really no way to achieve some more recoil? My JT (made by Bigtanks) allowed me to install even 150 mm recoil length which was the stop point for a very hot gun.
kind regards
Gerhard

Hi,

sure, it will be possible. First thing is to turn out 80mm of the barrelmount, and make a new teflon sleeve. The main Problem I see is, the length of 140mm recoil way. This long way is only possible (scale) with compressed air. The solution (and all others too) need much of space (rails for guidance, cylider, airtank and so on) behind the front armor wich will collide with the batterys there. So in my opinion, this effort to get the scale 140mm recoil is too much. If I retired in 27 years, maybe I will think about it and make a drawing :mrgreen:

Did you have pics of your JT recoil? How did you build the mechanic inside?

Sascha

Hi Sascha,

okay, with the light weight Bigtanks barrel made of glass fibre braid I had much less trouble to realize a long recoil way and a sufficient slide bearing. I only had to use a servo with an extended horn and a slide bar for the end of the barrel. But I think this solution might also be possible with an Armortek JT, if a 60 kg servo is used. E.g. my Armortek Jagdpanther has such a solution for its recoil, realized by a linear ball bearing.

Barrel in foremost position:

I had to use rather flat LiFePO4 cells to get the available space for the recoil when the barrel is in maximum elevation position.

Hi Gerhard,

I had to think about the recoil last days... So I made a few scetches and I decited to build it. The plan is to install a 150mm Festo DNSU 16 Cylinder to get the recoil on the upper side of the Barrelmount. Beneath that, a rail to absorb the weight wile the recoil action. A small air tank with 0,4l and a compressor with valve, relais and so on. All the components are proven parts from my submarine models. More soon, now I have to made some CAD work to fit all parts together.

best regards
