Thread: Anyone heard of RSB??

What a little ripper, outstanding score.

There is an RSB lathe on lathes.co.uk. The logo looks the same as the one on your drill.

Sorry I cant add any more info but I did manage to find a photo of Miller & Co.'s South Melbourne premises from 1938 on the Museum Victoria website.

Greg,

That is great info…. I now at least know it came from the UK.

Looking similar to the well-known "Relm" lathes, the RSB might have been made by Breeds, in Leeds, a company with a connection to Relm and whose lathes were sometimes branded "Atlas".

Started cleaning it up today.



I'm wondering if this is mean't to be a ball race for a bearing?? Also what are you supposed to use to tighten those collars? It looks like they have used a mallet & punch.

Not quite sure why this grub screw also has a nut.

Rear mount point for the pulleys to the base or motor mount.

Feed handle raises the quill and gravity feeds it, I think maybe a spring is missing from the top which would reverse this.

Looks to be an adjuster for side play on the quill.

The lock nut holds the setting.

May be a brass or bronze plug at the end of the bolt ?

G'day Desel,
I reckon the v-belt pulley is not original and would have originally been a flat belt type.
The drill in the attached brochure page, although a bit different, might give you an idea as to how the idler pulleys might have originally been set up on yours.
If I had to guess I would bet that yours was driven from an overhead shaft so the idlers would be positioned for the belt coming from above rather than below like the one in the brochure.
It looks like a really nice restoration project, good luck and be sure to show us how she finishes up.
Cheers,
Greg.

Yes that drill is "similar" and the vee pulley is definitely an add on as is the fabricated motor mount. It would have originally been flat belt drive, and set up in terms of pulleys very similar to the burke, which is the same as the junior and many others. Mine is actually a bigger drill than those but still a bench top drill.

Some did have a main drive pulley which connected to the line drive, others had their own motor at the base and connected where the line drive would be. These must have been around over a crossover period. Which of these mine was originally is unknown. Although based on the history of the RSB lathe it suggests that this was an late 1800s drill.

Actually re reading the image you found it says that, that model came in line drive and motor drive options.




I wonder what size the pulleys would have been and if there are some I can find or maybe some cast iron castors that could be adapted?

This is how I would eventually like to have this drill set up.


Only two speed or 3 speed maybe.

I estimate the large pulley should be about 4"x1⅜" and the speed of the driving pulley (aka motor speed?) 550 RPM based on various brochures.



This unit in the picture is a 10" Drill which has a height of 27½" Mine at a guess would be more like 40"


Any ideas on where I could get flat pulleys or what diameters I should be using???? were the belts a standard width 1½"???

Definitely think this was a thrust bearing but it has been castrated & lost its balls

Really thinking there is something missing from in here, There is a pin on each half and those flats must have served some purpose? Maybe a return spring?????? Any ideas??

This grub screw and nut hold the sleeve in place with that groove, do you think this is correct or modified??

The butchered grub screw here which has definitely been a hack job is filled on the end to work as a key. What should it have been?????

You might ask on the antique machinery section ... there are some post-drill guys there ... Vann for one ...

Re Alex Miller, I tried to find stuff here: https://www.woodworkforums.com/f152/dirtiest-own-181854

They were still in Melbourne 1972 at least ... from one of the photos.
They must have had outlets all over the place.

Cheers,
Paul

Thanks for all the pics, she looks like a beauty.

Sure looks like there should be a return spring in there to me.

Cheers,
Ew

Paul, thanks for the link. Looks like you found quite a few outlets.


Ew, I wonder if just a simple expansion spring was all it was or the two angled flats indicate more??




I have so many questions and the is so little info I can find. Some photos or adverts for "similar" drills, but they still don't show what is inside!


I'd love to know what mounted at the base? I can only assume it was a bracket for the stepped pulleys.

I deduce there was a two position arm with a locking screw at the elbow with guide pulleys. As the belt turns 90 deg over those guides I am thinking the tangent of the pulley would align with the centre of the drive pulley?? If I figure out the pulleys I can then work out the arc of the arm as it rotates between positions hopefully. Would the guide pulleys have bearings, or just greased up steel on steel? There isn't any bearings any where except for the one (thrust bearing) I believe should have been in the spindle.

How much crowning is required on the pulley and how much wider than the belt would they be?

What size would the second stepped pulley be if the larger was 4½" and how do I calculate the ratio of the pulley at the top to the pulley at the bottom and then to the drive pulley and to the rpm of the motor to get the correct drill speed. That is too much maths for me!

I also would like to know how the remove the chuck from the spindle. My guess is the spindle has a short taper which friction fits into the chuck?


This one might be easier to answer, drill chuck keys do they come in standard sizes?? It is missing on this drill and doesn't match the three keys I have. The chuck is un branded.



How hard would it be to set the table up perpendicular to the column and have the raised portion of the table redone on a surface grinder???


Ok I'll stop babbling on now…………..

Hi Dale,
I have info on the crowning of pulleys that I will dig up for you.
I also found the sheet you drew up for the drill specs you were after a while back (must do that).
Another thing I will try and locate at work is a 'Miller' brochure or any info we may have on them as a fair bit of our mining machinery came from Millers.
Great bit of work so far by the way.

Phil

Thanks Phil it be much appreciated.



I have been going over my options for the pulleys, finding existing ones (unlikely), modifying some steel castors (limited in size & width), making some seems like what I will have to do. I have considered steel, brass, and wooden ones. I may go with wooden ones at least to start with as a prototype, as you know many prototypes end up working so well they never get upgraded. I know the large wooden ones were segmented, in your experience do you think solid ones would work fine, and should the shaft run parallel to the grain?



I'm thinking the chuck may be removed like this??

Here is a start. I know I have more so I will keep searching.
