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I have tried Drags, they list a 6430-40 for WNG but theirs is 5 inches long, as is their 6430-39 (same parts) listed a superseded so not the original spec.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

Re: WNG long twistgrip
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

Re: WNG long twistgrip
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.

Re: WNG long twistgrip
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

Re: WNG long twistgrip
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.

Re: WNG long twistgrip
Did you make the brass bit for the cable Ray? Lathe plus rotary table in the mill perhaps?
