Turret access hatches were made in the already mentioned way, using clear acrylic rod turned on a lathe and detailed with some plastic card. The smoke dischargers were made from aluminium tube cut to the correct length and attached to a plastic strip  mounting bracket. I added the protection plates that cover the smoke dischargers by cutting some thin aluminium sheet from a shaving cream tube. These were then bent to the correct profile and attached with superglue.  

The two turret search lights were made using sprue drilled out to the correct diameter and attached to mounting brackets. Antenna were made from steel fishing wire attached to plastic mountings, these were then superglued to the turret. The commanders rough aiming device was made from thin aluminium sheet cut to the correct size and attached with superglue. The turret extraction fan was made from sprue and strip and added between the two turret hatches.  

WHEELS:

The Ratel has seven wheels which I needed to scratchbuild. This was the most difficult part of the model. After a couple of attempts I finally got one which was acceptable to me from which I could make copies. The process of making the wheel started with a number of pieces of plastic card being glued together to form a lamination. This was then cut to a rough cycle. The piece was then placed on the lathe and turned unto a disk. The rim detail was then turned. The wheel was cut to the correct shape. I made the tyre part about 1mm smaller than needed as I still wanted to add thread to the tyre part. I then cut a piece of plastic card with a hole and inserted the wheel into this piece of plastic card, this formed the centre guide for the tyre thread and divided the wheel into a left and right section. This piece of plastic was then glued and trimmed on the lathe to make up for the lost thread. I then cut small diamond shaped pieces of plastic card and attached this to the entire tire running surface on both sides to represent the thread.  I then put the wheel into the lathe and sanded al detail to achieve a even surface. This worked quite well and I was happy with the results. I then decided to make copy the wheel. I added some black tint to the resin thinking that this would represent the tyre the best. I did not like the results as the tyre was too shinny. I then cast he rest of the wheels in the normal buff colours resin. One wheel was then placed on the lathe and the rim hollowed out to form the back of the wheel this would then serve as the spare wheel on top of the hull. I added the locking device for the spare from plastic and thin copper wire. The rims were painted in the SADF brown and the tyres in dark grey.
