Hi Patrick.
Yes I have fitted rubber pads to my tracks successfully.
I went to my local cobblers (shoe repairers) shop and bought a piece of rubber sheet aprox 6inches x 12inches and 3mm thick for about £3-00.
All that remained was then to cut it into blocks the size of the track pads, chamfer the edges of one side only then fix to the track pads with a good quality superglue ( I use 'ZAP A GAP') which has held well for me so far.
Photos to follow soon.
With regards to your earlier questions, The steering servo I used was a standard Sanyo servo which came with the radio kit.
I have looked on ebay for the diff that I used but have not yet found any,
the type I used is an HPI 'MT' two way diff but I would think any TWO WAY diff would do the job, dont get a ONE WAY diff as that will not allow you to go in reverse as it is designed for petrol car use (FORWARD DRIVE ONLY)
Hope these comments help,good luck with the build.
Cheers, Noel.

Question:

1/ Why use copper pins? (no rust? or better colour?)

2/ How do you plan to hold them in?

3/ Does the rubber go on the plastic top pad?

Thank you for the info, I will go to my bootmakers and get said rubber sheet. Also thank you about the diff, I would have made the mistake of getting the wrong sort of diff. :oops:

007kiwi:
1/ Yes no rust and softer on the plastic and the steel ones are only held in by the splines at one end as you can see in the snap. :P

2/ The pins are held in place very tightly by the ends of the track links. For the last bit of the link I had to force the pin in with a vice. The link pivots at centre of track link pin only. :lol:

3/Yes. :) endee's information will be used.

Fabrice:
Yes good idea I will have a look at buying a complete car, maybe 1/10 scale Tamiya and canabalising what is needed. :idea:

First track is finished. I am glad I did this first as I did not realize how repetative and brain numbing it could become. If you get one of these kits I would suggest that you do the same as it gets the uninteresting bit out of the way.

Image

For the second track I will mostly be fixing the links with hollow 1/8 inch diameter tube. The tube will be tapped to 8 BA. Then I will fit steel 8 BA bolts which have 10 BA heads. A full size 8 BA washer will be used. I know this will take longer, but it looks much better. The BA bolts with smaller than normal size heads are well known in the Live Steam model engineering world.

Image

The next snap shows how much better the 8 BA / 10 BA fixings are?

Endee,
I have notice that the diff in your model is offset from the centre line. Why is this?

Funkner,
Its one I have considered before but I have far to many projects at the moment some will never be built so I may have to have a clearance to make some space I also have a 1/6 Tiger that needs a lot of work so we shall see maybe after Christmas

Adding texture,
The 250 like many German armoured vehicles was constructed of slabs of armour plate. Armour plate is not perfect and has a pitted surface.
The ARMOR HOBBIES 250 has an very shiny and smooth finish.
Pitting can be replicated by the use of a very small round-headed dental burr.
With the drill turning at a very slow speed and using the smallest round headed dental burr texture can easily be added to the surface of the 250.

[img][img]http://i56.photobucket.com/albums/g164/ ... CN1328.jpg[/img][/img]

Using the edge of the burr a very light pressure is best, no more than the weight of the drill.
To much pressure will result in to much texture and the 250 will look like a concrete sdkfz.

[img][img]http://i56.photobucket.com/albums/g164/ ... CN1329.jpg[/img]

After pitting is complete with the dental burr the excess plastic swarf may be removed carfully with a scalpel.

To finish I have smoothed the surface with 1200 wet and dry.

Those plastic grills will have to go!

I want to add a weld edge to all those smooth corners. Any suggestions?

I will not be using the ally axles or chrome plated screws which hold the wheels on which came with the kit. The items supplied with kit are at the top of snap.

[img][img]http://i56.photobucket.com/albums/g164/ ... CN1337.jpg[/img]

I will be fitting steel axles and to hold the wheels on I will use 6mm cap heads. The replacements can be seen in lower part of snap.[/img]

I have just had yet another look at the superb Armourpax's Armor Hobbies 250 completed.
I think I might as well give-up now and go back to making lace :oops: :cry:
