I need to decide which tank to do..

But headlights and IR light are things I need to make

Need to order 2 more wheels as OZ ones generally have 2 wheels on the front and we used different headlights

Cheers

Sean

Hi Robin - great work so far. I like the little extras re the bin handles. SImple solution yet effective result.
How are you doing with your catches and filler caps? Did you have a pattern, or have you made your own? Would love to hear how you do this in the absence so far of commercially available add ons.
Regards
Kevin

Hi Kevin,

I'm in the process of trying resin casting (not very successful yet :( ), the master catch was made from plastic strip and a paper-clip, I need to cast 20 (this includes 8 for the turret bins). I copied a picture I took at the Tank Museum and basically guessed the size :) , only the paper-clip part will be workable
I've also built a filler cap again from plastic strip and ground it into a round domed shape, I came up with 2.33cm diameter in 1:6 from roughly measuring the AFV Club 1:35 model, may be too small?

All very interesting Robin - let me know how it goes.

I reckon I need a day at Bovvy or anywhere else I can fill an SD card with pics of these Centurion details. I'm in Guernsey so will have to wait until the New Year now. Meanwhile I continue to read books, glean what info I can from pictures on the web and of course in this forum.

Regards

Kevin

Hello,

Much better weather this weekend, sunshine 8)
Finally acid etched the main hull parts.

Should get them together over Christmas.

Here is the master filler cap:

The mess is from all the grinding :)
I may be getting closer to success with the casting, it seems to take much longer for the rubber to set than the 24 hours stated. The latest attempt is solid but sticky, I'll leave it another week.

Good find Neil, good price too, I spent ages looking for jewellery box catches.
The lower main body of the catch may not fit on the lower part of the box though? looks about 20mm?

This is a halfway holiday report :)

I created the missing bolt detail around the centre by glueing on spare nuts and filling the centres with Milliput.

I'm not sure if it's that easy to see, but I created some cast texture with Tamiya putty on the idler mounts.

Looking good so far guys.

I see you addressed the "missing" bolt detail from the drive sprocket. I used M3 bolts and nuts to achieve the same thing, the cap heads fitted inside the hub with no fouling the taper lock bush.

I am going to try and fabricate the locking bar set up for the castleated nut at some point so i will post pics when that is done.

Keep up the good work, Mick

Hi, I have a quick question about the idler assembly, in the instructions it says the axle should be screwed fully and firmly home but I end up with a gap at the swing arm face which translates through to the spigot eye only having half the shaft inserted:

I'm worried this may affect wheel alignment.

Thanks,

Robin

Hi Paul,
I had the same result in my first fit, the axle needs relieving a little where the threaded portion butts up to the arm.
I did this in my lathe but you could manage it with a small file. The lack of a relieved area stops the axle screwing
Right home. Hope this helps, Mick
