49 Rigid help needed with the frame
« on: 17.04. 2017 17:31 »
Is there anyone out there with 1949 Rigid A7?
I am in the process of dismantling mine for restoration and need info on how the rear sidecar mount is fitted.

I have tried warming this area up with a butane torch (maybe not hot enough) and using a 3-foot-long lever, but it won’t budge! the teeth marks in the photo aren’t down to me by the way.
Can anyone confirm if there is a thread in the frame lug please.

I would also like to fit a centre stand but can’t see how this could be done, there appear to be no sensible fixing points. Any suggestions please.

G'day Allan,  *welcome*
I can't say for sure but I'd put money on a thread. Is there a similar lug on the other side?

While your waiting for the longstrokers to show up, head over to Pictures, Stories & Intro's and tell us your story.
Cheers

YA7 (1948) frame has a stud with a right hand thread. More penetrene and more fire  *eek*
The centre stand should have cast on lugs below the frame down tube.

Many thanks for the replies guys.
I have a copy of the original spares book for this model and it doesn't even show a rigid frame, I was most disappointed as I bought it just to verify that the lug was threaded.
I have a stand like the one shown in the Draganfly catalogue, which I had purchased as new old stock from ebay, there is no way that it will go on the rigid frame or even the 49 plunger frame that I have (no stand on that either).
Is the photo on Peters post a pivot pin for the plungers stand?
I have other photos but could not work out how to insert them in the text *conf*

This may or may not help.

Photos from 1949 parts book which covers all models in the BSA range.

First photo , the part indicated by the arrow is, I think, the part in posting above. It is described as "sidecar chainstay lug stud" and is for the rigid A7.

The second photo, the part indicated by the arrow is obviously the rear section of the frame but is described as "Chainstay and backstay complete"

The third photo is the frame front section

The fourth photo shows the centre stand and the same part is listed for rigid and plunger frame.

Hi,
Here is a link to the forum photo guide
http://www.a7a10.net/forum/index.php?topic=427.0
Remember to reduce the photos to a managable size, There are quite a few free programs to do this

ON the Draganfly web page you can see two lugs sticking down from the cross forging at the bottom of the seat tube
It appears that the stand should fit to these with two short pins 67-4848

 Picture is of my Plunger centre-stand;
Note the top of spring is not stock, it busted a few months ago and I bodged it *smile*

 Photo taken on Samsung Galaxy S5 using "Photo- Resizer" for Android and it works a treat. Can re-size existing photos or use it to take a photo.
  It throws ads in occasionally, but hit back button and they go away. I've been using for a year or so now.

 Not sure if it's available for iPhone, but think it is. (Photo of Icon attached)

Thanks for posting the photo Dutch.
I have a plunger frame from 1949, the frame number being prefixed by ZA.
Hopefully the photos will appear below, there are no centre stand lugs but someone has welded on a lug for a side stand.
I have photos from my rigid frame (also a ZA)  but its the same as the plunger.

 Al, I posted the pic so you can see where the stand lugs are, and your Plunger frame looks to have rough bits where they've been cut off - I can't tell with the rigid frame

  Me neither- sometimes I just happen to have a couple on hand, and have a couple of boat chandlers close by if I need things *good3*

Here are some more photos of the underside of both bikes, I cant see any evidence of lugs being cut off.
It would be strange to have the lugs removed from both bikes.
Could these bikes have had a rear stand, even though there is no sign of any?
My rigid A7 was attached to a sidecar, possibly from new, maybe a sidecar spec bike would not have been fitted with a centre stand.

 Uh yeah- can't suggest anything else, in the other Plunger pic it looked like roughness where the lugs had been but just distorted paint    *dunno*... unless it was a seriously intended removal   *dunno*

Er DuTch, I think your wheel alignment may be a tad off!
