March Update: More Turret Modifications

Thanks for the encouraging words gentlemen. I needed a light kick up the derrier after the distractions of Christmas, tax returns and other delights.

Actually I haven’t been idle.

First off here’s a few pictures of the remaining work on the turret ring, etc.

Taking my lead from other postings on this site I decided that the turret needed some extra stabilising where it sits on the hull. This is especially necessary if, like me, you are replacing the bb gun with the Asiatam recoil unit because the metal barrel makes the turret rather nose heavy. I was also keen to try and disguise the fact that the (relocated) turret ring is still far too small.

First I acquired some of those sprung ball catches which are used to keep cupboard doors shut. I drilled four holes in my turret base and then glued them in place with copious amounts of glue and short lengths of brass tubing used as sleeves where they protruded above. In the end I decided that the rear one wasn’t needed.

These were placed so that as the turret revolved they would run around the hull top. I order to hide them – and to give the illusion of a wider turret ring when the turret was viewed from the side – I then cut out a plastic ring of the right diameter which I glued to the hull top. Note that this is not supposed to be the turret ring splash guard which was fitted to late model Tigers.

Incidentally, I found an excellent and cheap compass cutter for this purpose made by Jakar – the same people who made my cutting mat. For us Brits it’s £4.25 including postage on Amazon:



It is a little light to cut into thick plasticard, but the trick is to use the blade to score deep enough so that you can then separate by gently bending the card.

NOTE: Later on I found that, although the plasticard ring made he turret revolve smoothly, it also made it sit too high. So I removed it and all of the ball catches apart from the one at the front. The turret revolves fine...

Now I needed to make two structural alterations to the inside of the turret. Again these were for the installation of the recoil unit. I will deal with the actual wiring of this in due course – having only just mastered it myself!

Because I had removed the old commander’s cupola I had also lost one of the internal mounts for the old bb hopper. This is supposed to be one of the anchor points for the Asiatam recoil unit. Here I improvised by bending a thick piece of brass strip into a rough ‘S’ shape, gluing one end to the turret roof and drilling a suitable hole in the other. I then used a small nut and bolt to attach the recoil unit.

Another unforeseen issue was what I suppose I should call ‘Tiger’s droop’. The metal barrel is so heavy that it naturally sits on the bottom of the barrel sleeve attached to the mantlet. My solution was to glue a thick brass strip inside the bottom to keep the barrel properly centred where it protrudes from this sleeve.

Incidentally, I have also just discovered the joys of adhesive Velcro strip. This is very useful for keeping things from sliding about inside the tank whilst also allowing them to be easily removed when needed. So, for example I, I Velcro-ed the gun flash battery onto the inside rear of the turret.

Eventually I was able to reattach my turret floor and get ready to turn it the right way, mount it back onto the hull – and pray that it all worked..!

Your posts sir are a wealth of information. Too bad you weren't interested in the Panther or I would have mined you for details as you undoubtedly would pour as much effort to it as you have done for the Tiger.

Well, funnily enough my youngest son has an HL Panther... But I've got to finish this beast first!

Working hull MG ball mount

I did a separate post on this several months ago, but this is my refined version. The original HL hull MG leaves a lot to be desired. The older models (like mine) didn’t even come with a flashing version and the newer one is certainly an improvement, but there is nothing to replicate the working ball mount which they do provide on their Panthers.

One quick fix is the Asiatam insert which simply sits inside the aperture. It looks fairly convincing (although it’s not set in deep enough) and does at least allow for an improved flashing MG to be fitted.

My rather Heath Robinson-esque solution involved the following:

First I drilled out the aperture completely and used a spherical sanding fitting for my drill to shape it from the inside.

Then I found a suitably sized plastic bauble from a cheap girl’s hair band (in a lovely subversive pink) which I drilled out to accept the Asiatam MG with an additional hole for the sight.

This was then boxed in internally with some thick plasticard. One I had done this I realised that, although the gun could swivel left, right, up and down, it could also twist on its axis. It shouldn’t. Accordingly I inserted a metal pin in each side and cut matching slots in the sides of my plasticard box to prevent this.

The ball I used was actually too large (it should be about half the size) but once it’s in place behind the mount I like to think it looks pretty convincing.

By the way, I was worried that when I wired up my Asiatam flashing MG to the HL circuit it would blow the tiny LED (there was a warning on the site where I bought it). Eventually I plucked up the courage and it was fine.

If you leap forward you will see how I changed the zimmerit...

Why don't you just box the ball insted of putting it on a axis? Then you could get movment in all directions...

I did simply box it in at first, but that meant it could still twist. By adding the pegs and slots I still have full lateral and vertical movement, but the gun and sight aperture remain in alignment... Does that make sense?!
