Looking at period pics the WNG twistgrip it is quite a bit longer than the standard Amal type. I have read on another forum that they were 7" long (inc the housing) compared to 5 1/2 for the normal one you see, and the photos seem to bear this out. The extra length is present whether it has a rubber grip or the later canvas one. The 'dummy' grip on the left side is also longer than normal, about 6 inches compared to 4 1/2 normal.

Looking at the parts books the dummy grip 6430K-39 is the same part number for the WNG AND the 1939 singles meaning the singles must also have had the longer grips fitted ?.

The twistgrip assembly is 6430-40 for the WNG and 6430-39 for the singles. I am assuming the difference is because the WNG did not have a chrome plated housing but could be wrong?

The 1944 WNG parts book gives an Amal part number for the twistgrip 16/117C....the C I think is for canvas. It is still the long version as shown in the bottom image of an original 1944 WNG. There are 16/117’s listed on Ebay but they are the short ones.

I have tried Drags, they list a 6430-40 for WNG but theirs is 5 inches long, as is their 6430-39 (same parts) listed a superseded so not the original spec.

So...does anyone have any leads on where I can get a longer twistgrip? I saw a NOS with canvas grip went for £102 on Ebay earlier this year !!

Try Stuart Bray, he lists a lot of wd parts.
And deals in ex wd bikes.

That part number goes right back to the 40 models .I can't see a problem lengthening the shorter one. Does anyone have the dimensions of both.? Nev

Anyone enlarge the classic short grip or are difference?

Why don't you make one? I purchased a stock piece of aluminum seamless pipe on e-bay and machined to size. The brass part is pressed on, as the original.

Hi Ray!
Many thanks for the pics.
Can tell me the lenght of the tube?

Hi Luis.
You will have to get dimensions from one of the W/NG guys.
The one I made was for a civilian Ariel having 1" handlebars.
I did have to enlarge the inner diameter slightly and machine the outer to match the original.
Make it a bit on the longer side. It will be easy to cut to proper length later.
This is not a difficult job, if you happen to have a lathe or access to one

Thank you Ray, i have a lathe.... i have 2 Lathes!
One in my house

One in workshop




Alan above say the lenght, but know the correct tube length , it would be better!

Hi Luis,
I would make the part over length by an inch or so and press the brass cable holder on. I would then check the inner depth of the canvas or rubber grip you will be installing.
This should give you a pretty accurate length. Find out what is the standard, stock length for the long twist grip mechanism to be sure you are within the ball park.
BTW, nice lathes. I used a South Bend "Model A" similar to your green one.

Did you make the brass bit for the cable Ray? Lathe plus rotary table in the mill perhaps?
