Ariel W/NG (Unknown Part)

It's listed in all the parts books as "Prop Stand Stop Plate" #1454-40. Hardly anyone seems to know about it including Ariel experts. I've got this "factory" picture and scaled it up the best that I can and made a copy from 3mm plate.

I've no idea why it was considered necessary? Along with Ariel's thinking that the regulator under the saddle should need a metal shield/watershed? But interesting items to make and fit. (Thanks to Mick Holmes who made my watershed....He had a pattern) Ron

Re: Ariel W/NG (Unknown Part)

Hi Ron
I can't figure out what that "stop plate" is supposed to stop. It looks like it'd only stop the stand from rotating vertically.
Does the entire propstand & mounting bracket unit rotate on the bike's mounting lug?

Re: Ariel W/NG (Unknown Part)

Bob it just stops you swiveling the prop stand up any higher when you stow it in the spring clips. To my mind, the bottom of the pannier frame would do that anyway. My only other thought, is that it might help you to locate the holding clips whilst sat on the bike??

Here's my bike before I added the stop plate. The part number indicates that it was fitted to all W/NG's from 1940. Ron

Re: Ariel W/NG (Unknown Part)

Does it keep the rider or pillions leg away from a sharp point?

Re: Ariel W/NG (Unknown Part)

I don't know Ariels at all, but in that top photo, it looks to me like an L-shaped bracket, one end of which forms a double-sided tab washer around two flats of the pivot bolt (or nut). Does the "stop plate" simply stop the pivot bolt from turning / coming undone ?

It seems to be a wasteful large part if that's what it is.

Re: Ariel W/NG (Unknown Part)

Nothing like that Rik. The pivot bolt has a locknut anyway. But I've managed to download another picture. Ron

Re: Ariel W/NG (Unknown Part)

Could it have possibly been to guide the prop stand into its spring clip before the introduction of panniers made it unnecessary?

Quite so Hamish, but why carry it on right through to the 1945 models?:thinking_face: Ron

Re: Ariel W/NG (Unknown Part)

It seems incredible that not a single example is known to have survived. Not even in NOS boxes. Were they actually still fitted, or did they forget to remove them from the lists?..or perhaps it was deliberate as deleting would have meant a Ministry of Supply costings review.

Re: Ariel W/NG (Unknown Part)

Is there any info in the rider handbooks, will look at some photos when I get back home this evening.

Re: Ariel W/NG (Unknown Part)

This is the factory picture that I'm using. ( from memory I paid £35 for a hi res copy from IWM) It's from a late 1944 contract S5514. Ron

Re: Ariel W/NG (Unknown Part)

Ron, I can't see why a guide would be fitted that high. It would work better lower down.

Could it be spring steel and might its job be to stop the stand from pivoting backwards if the stand has been pulled down and as the rider dismounts. Is there any other system that prevents it swinging around ?

Where does this stop line up if the stand is extended ?

Re: Ariel W/NG (Unknown Part)

No info in the rider handbooks,the photo below of an RAF Ariel with out panniers shows the plate but bent upwards,the stand has been removed for some reason,has the stand bent the plate upwards?


There is an unrestored WNG used by the German army,but cant find photos at the moment,but cant remember if it had its side stand still fitted.

Re: Ariel W/NG (Unknown Part)

So you've just got astride your W/NG while it is on it's field stand, pulled it upright ready to start it and holding into the twistgrip with your right hand you twist round and reach with your left hand to get hold of the field stand to stow it in it's clip.
But you can only reach about 1/4 of the way down the field stand which makes an accurate slotting of the free end into its clip happen about 1 time every 4 attempts. Unless you have the guide plate!
Stand raised against against the outer underside of the guide plate and a smart push inward snaps the stand straight into its clip.
Individual prep of the machine would involve adjusting the plate position up or down to ensure accurate alignment of the plate/stand/clip (with a hammer).
Just another example of the level of finesse applied by Ariel.

Re: Ariel W/NG (Unknown Part)

Yes Rupert, exactly my initial theory. But still strange that so far I haven't come across an original or heard of anyone that has? Ron

Re: Ariel W/NG (Unknown Part)

Easy part to regard as superfluous, remove and throw away...

Re: Ariel W/NG (Unknown Part)

Yes I guess so.

Will you be at Cheddar tomorrow?
four of us are going to give it a go. The route will still take us past Morrisons at Wincanton where we look forward to breakfast!! Ron

Re: Ariel W/NG (Unknown Part)

I can't see the point of it and I think it may come under the heading of silly ideas...I know the Ariel has a different stand clip to the M20 version but in that case fitting the field stand to the clip while seated on the bike isn't something I could manage I don't think, the clip exerts too much pressure on the stand leg and the leverage from that position is poor..But then that may be why the M20 doesn't have the stop plate....Does the Ariel have a measurably more 'limp' stand clip than the M20?...Ian...
