Thanks guys - but I'm not going to give up the day job just yet...
Now, over Christmas and New Year I have been doing what I hope is the last major structural work on my turret... (he wishes)
This one's a bit convoluted, but it all started with a problem I was having with my turret elevation.
Some of this will only be of use for those with the Taigen recoil unit installed in the Heng Long Tiger 1, but most will also work on a standard BB tank.
Correcting the front of the turret roof

I have already covered the basic problem with the front of the Heng Long turret above. Basically, the turret is a little too long-nosed - presumably to accommodate the bulky BB mechanism and the elevation motor at the rear of the turret. I elected some time ago not to try to change this, rest assured, I HAVE NOT CHANGED MY MIND.
However, I was also having some problems with the elevation of my Taigen recoil unit, which kept on sticking at maximum elevation.
When I looked hard at it I realised that there was something else odd about it - the maximum elevation was very high (the mantlet went right to the top of the turret roof) while the lowest elevation (or maximum depression) barely reached horizontal.
Whilst (ahem) a nicely erect gun is fine for a vehicle on the march (when the breach was secured inside the tank by a lock to prevent damage by vibration), it does not look good for a tank in the field - let alone in action. After all, any tank's ideal firing position is hull-down aiming at targets slightly below the horizontal.
Now I have no idea whether this is a problem which others have experienced with the Taigen recoil unit, although I have read elsewhere (and I agree) that the degrees of elevation / depression are rather limited compared with the BB firing model.
So I tried to think of a way of fixing it. The solution I came up with simply involved adapting the resin elevation bar which comes with the Taigen unit. This has a slot which fits over a crooked gear shaft in the unit, meaning that when the shaft (and hence the slot) is at it's lowest the gun is at its highest and visa versa. Bear in mind that in most photos (including mine) the turret is upside down whenever this is shown.
So, in order the
reduce the elevation and increase the
depression I needed to I needed to change the position of the slot so that it sat
higher and thus the gun
lower. And all this is upside down! Got it? I did - eventually...
So here's my 'simple' fix:

- The resin elevation arm from the Taigen recoil unit was cut with a razor saw to a depth of about 2mm.jpg (27.62 KiB) Viewed 3958 times

In my next post I will explain why all this was also necessary to correct the front of the turret roof (I also changed the front of the turret sides). In a nutshell it is this: if the gun elevates less you can better replicate the true appearance of the area behind the mantlet. What you want to change is this:
