The Official Armortek Forum - World leader in one sixth scale metal kits

Hi Guys

When screwing in m4 * 10 CSK to the end of shaft CE256 it says to shim if required - would it not be more elegant to use a shorter screw.

Also is a shim the same as a washer?

thanks

Bob

Hi Bob

Although these shim washers were not mentioned in my version of the Tiger 1, I still used them but could not remember the exact reason why I used them. Had a look in my build log and it became clear why I resorted to use them.

viewtopic.php?p=61561#p61561

Under one of the photos I wrote, "Wheels were locked in place with the kit supplied fittings and using 0.1mm shim washers so that when the screw is tight the road wheel will still turn freely. Most wheels only needed one shim washer but three wheels needed more than one shim washer."

When I was tightening the countersunk screw, the road wheel was either locking up or it became difficult to rotate. The shim washers were used to be able to fully tighten the countersunk screw and keep the wheels free wheeling. Shortening the screw will not solve the problem.

Shim washers are usually very thin washers used for adjustment purposes. A normal washer is too thick and will most probably introduce another problem, namely, lateral play in the road wheels.

As you can see, these washers come in various sizes and thicknesses. They can be stainless steel, steel or brass. I think I used the 0.1mm washers and added as required so that when the screw is tightened, the road wheel turns freely and there is hardly any lateral movement of the wheel.

Hope this made sense.

Thanks for the advice Vince.
Now I can't get the torsion bars to fit as they are too big.
Do I drill out CEO256 a smidgen or shave a bit of the end of the torsion bar.
many thanks

I don't understand what you mean. Remember that my Tiger is an earlier version than yours but I suspect that the part numbers are the same. On mine, the torsion bars do not go in CE0256! They either go in CE0259 or CE0260 depending on the size of the torsion bar. At least on mine there are 5mm and 5.5mm diameter torsion bars.

Also if the parts are not properly deburred than that could be the cause of why the torsion bar is not properly fitting.

OMG Vincent - I am a total numpty.

I just assumed that the torsion bars were the all same.

I did wonder why they were in two packs!!

Thanks so much for your advice.

Thanks God I asked on the forum and you were there otherwise I would be asking Armotek
for a load of replacement parts.

All the best

Hi Bob

I found I had to dress the ends of the torsion bars with a file for them to slide in correctly, also check the holes where the grub screws go in as that can also stop the torsion bars sliding in cleanly.
Good luck with your build.

I need all the luck in the world to complete this build Gary!!
So many pros on this site and I am just a noob although I have nearly finished the UC so I thought I was getting better
I painted the UC but this one I will probably leave unpainted.
Also using plenty of Loctite that gets everywhere!!
all the best

If Its any help Bob,i labeled my torsion bars and arms with model making masking tape and marked the Armortek ref to the label,some months down the line i am now able to ID the arms and bars at a glance as they have been test fitted and painted a few times since first unpacking them,but it was a great help at first as i too didn't spot the different sizes of bars at first myself,there is also a small dimple beside the grub screws holes to ID the different sizes of arms,i think Vince points this out on his build

hope it helps

With regard to the original question regarding shims, it should not be necessary. I had this issue on a couple of wheels on my build, but it was because the bearings were not properly seated - my fault. Check this first! Of course, every vintage is different and there is a chance that an occasional wheel actually does need shimming.

Hi Guys

Many thanks for all your advice.

It's quite a project for a noob!

Not least the weight of the thing - how on earth does anyone turn it over?

Just ordered a table lift.

thanks

Bob
