hi, first post here. Very interesting forum. I am looking for some help please. After much searching I have finally got myself a small Randa lathe. It was missing the change wheels. Even more searching and I have now got a full set of gears too.

I now need a banjo or change wheel carrier so I can connect up the Leadscrew feed. Does anybody have a spare they could sell me, or good pics, or drawings of one. I feel I could cut one from some 10mm plate, snd weld on a boss/clamp.

Thanks in advance.

Kind regards. Paul.

They look like the banjo pivots on the rear leadscrew bearing part and is nipped up with a nut + collar
 
These look very similar

Yeh, thanks Ady.
I have seen that site. I actually have a grayson one. What I need are the length of the slots and the position and angle that the second slot runs off at. It does not look like 90 degrees.
Thanks, Paul.

That looks like a very close relative of the Myford ML4 to me. I parted with mine some time ago but I'm sure someone here has one.
 
Cheers

I've got a genuine RandA one. Give me a day or two and I'll find it and scan it.

Hi Paul, below is a photo of the bango as fitted to the "New Type A & B RandA 3" " lathe. There are a couple of other views in my RandA A & B type bango album.

 
The total length of the straight slot is 3" X 1/2", the curved slot is 2.2" long by 1/2" and is on a radius of 3" centre to to centre of the split mounting hole, the hole is 7/8" bore and is 1.38" long. The striaght slot starts at approx 1" from the centre of the mounting hole. The thickness of the slotted part is 1/2" X 1.45" wide near the hole, and 1.7" around the hole, but the rased portion of the hole is 1.4" in diameter. The curved portion of the slot is 1.2" wide. The pinch bolt is 1/4" BSF. The split running the length of the mounting hole is approx 1/6" wide.
 
Hope this helps.
 
Regards Nick.

Nick,
Those pics are great, just what im after! Thankyou very much for taking the time to give the measurements too.
 
Ive spent a long time searching on line for pics like that with no luck. These forums are great.
 
If this banjo is a spare I am willing to buy it from you should you wish to sell.
 
Chris if the one you have is for sale, then the above also applies to yours!
 
If I cant obtain one then I will get my plasma torch out and fab one to these dimensions from 1/2" plate, with the boss welded on. I cant see any advatage of having the raised section around slots, unless anyone knows better?
 
Thanks again for being so very helpful.
 
Regards Paul.

Hi Paul, glad to be of help. It shouldn't be to difficult to fab one up. The raised section around the slots is most likely to save on metal in the casting prduction process.
 
Sorry mine is not for sale.
 
Regards Nick.
