I'm not convinced either, the may have been some relationship between the companies in the area but they seem to be distinctly badged not producing items under a joint name. Dunno.

Does it give any specs in the newspaper ad, or what it sold for??

Thanks for that. Did you get the same spec spring for both the Waldown & Servian?? I see the come in different lengths and coil diameters. I would suspect this in turn equates to tension or force required to pull the lever forward and potential kick back.

Full travel of the quill in my drill equates to a 280Deg rotation of the handle…. Would a smaller spring be better in my case?? Not sure how to select the appropriate one..



I also note that they suggest using them as vacuum cleaner coil spring, volume tube coil spring, safety belt coil spring. Pity there is no hard rubbish currently, I may have been able to find a few to test from old vacuums. I assume they are use to retract the cord.

Hi Dale,

The reference appeared in the Sydney Morning Herald on 19th August 1931, in a machinery auction listing.

The SCRUTTON RSB might be a clue... but so far it hasn't led anywhere usefull..

SCRUTTON RSB Pillar Drill, R and F Table with 7½In swing, Cone Drive.

R and F - I assume that to be rise & fall.

First I have heard of Scrutton.

About the only kind of relate Scruton reference I could find, they had a foundry and exported but looks like the wrong kind of product.


ABOUT WILFRED SCRUTON LTD

Wilfred Scruton Ltd is a well known and family run business located in the heart of the Yorkshire wolds. We have evolved over the last 100 years to become one of the main Agricultural Engineers/Dealers in the country and worldwide export.

Wilfred Scruton Ltd is a long-established and family-run agricultural machinery dealership. The business began in 1896 as a foundry, casting plough shares and fabricating horse ploughs etc. incorporating a joiner’s workshop repairing cart wheels, sheep troughs and tumbrils.
Of course, this was all back when farmers bought locally-manufactured implements from their local blacksmith. As the industry had evolved, so has the company; with our customers reading articles and visiting events worldwide to find the most appropriate machinery for their budget and requirements, the company has gradually grown into a dealership with local and international suppliers.

Scruttons may have been Like Miller Machinery on the brass plaque a reseller, again similar to McPhersons. Or maybe a local manufacturer with some links to the UK?

I selected mine based on images of the Servian and the broken spring in the Waldown - and the width and diameter of the space available.
I settled on 7 turns and 50mm diameter. Then I looked at the proportions of the spring thickness in their photo. The two springs I got were a little thinner material than the original Waldown spring but there is a fair bit of adjustment in their preload. I set it to go up lightly with the chuck on the quill on both.

Thanks for the info Joe.

Hi Dale, below is a scan of an illustration of a drill that looks similar to the one in your photo's. It is from a catalogue from a supplier by the name of Croager Bros. who had a place in Homerton, London. There is no date in the catalogue, but I'm guessing it was around 1939 as there is a footnote pasted in about certain piricees may be subject to change owing to the outbreak of war. It dosn't state what make except that it is British.

Not the foot shifter, so you can switch between the slow-fast pulleys and turn the drill on & off whilst still at work.



I'm following this guy up in the hope he can give me some details on the headstock cone pulley, bearings and any keyways etc.

I have a 'RSB' lathe which I have always assumed was made in the 1920's. For many years I have never been able to find any reference to RSB or ever heard of another machine than my own, or ever met anyone who has heard of RSB Sometime last year the 'Lathes UK' site suddenly published photos of a virtual facsimile to my machine and states that it is the only one known (although my own is in much better condition) Here is the link (for what it's worth) to the site page;http://www.lathes.co.uk/rsb/

Ok I have a question on bearing surfaces and tolerances.



The Spindle drive pulley would be fixed to the top sleeve by a grub screw or bolt. These turn as one and run directly on the machined top surface and the bore in the cast iron body. Note oil or grease nipple on front.



They are soley located by a groove in the top sleeve and locking grub screw through the cast body.




There is a second grub screw filed on the end to a key in the top sleeve, which mates with the spindle key seat and drives the spindle. Not a lot of surface area for power transfer. This doesn't look original to me.




The spindle has two locking nuts, over a brass thrust bearing race, the bottom of the race machined into the top of the quill.
Inside the quill is a oil groove with a side feed hole.




There is a brass Washer at the base of the quill, with a locating ridge running circular around the top mid point, mating up with a groove on the base of the quill.



The quill runs directly up the hole in the main casting. The casting does have a slit cut the full depth and a clamping bolt which will close the hole up on the quill slightly for adjustment.

So that is for the description, now for the questions:

• Where is the main bearing surface to keep the machine drilling square? No run out.

• How much run out is considered acceptable

• On each of these shafts and bore what tolerance/fit should there be? Also what affect does grease or oil have in this.

• The quill and spindle appeared to have black bearing grease on them, would this be correct

• Restoration vs repair - To make this drill a regular user should I look at adding bearing cases to the drill as per more modern drills? Keep in mind this drill seems to be extremely rare but missing a larger portion of original parts. Although new parts could be made and original ones kept with drill.

• In the thrust bearing would the loose balls have been packed with grease

• Are bearing cases more accurate and better than bronze bearings, or just less maintenance

Better look at the bottom of the table. Some pretty rough casting work really.

A few hours of hand sanding has cleaned up the pillar. Would like to using a buffing wheel and some rouge on it to get into the scratches and pitting. Don't have any of that kit though.
IMG_4991.jpgIMG_4992.jpgIMG_4993.jpgIMG_4994.jpg


Figure the locking nuts are supposed to be tightened with one of these…..Known as a Hook Spanner or "C" Spanner. Now where do I find one the correct size??????
I think those nuts need replacing also they are a bit chewed up.
IMG_4995.jpgIMG_4996.jpg
That nipple was full of grease, by the way.




Played around with making a little mock clamp for locking the arm.

You can get adjustable C spanners, they do say 25-50mm etc. I have bought mine locally, here is one on ebay though http://www.ebay.com.au/itm/Draper-Ad...item54052037e2

Have to look into it. Thanks

From memory it is someplace around 31-32mm those collars/nuts.

No I hadn't seen that and it is absolutely fantastic!!!!!

The model shown is slightly different to mine and I wonder if it is the heavier one mentioned later on.

Knowing the name: Messers. R. S. Brookman and Co. of Britain is a great lead. They say anyone interested can write to them for a copy of their booklet covering all machines with up to date prices. I wonder if they will still send me a copy

Interesting it mentions a number of optional table variations. mine I guess would be: The angled or drop sided table in the square.

http://www.london-gazette.co.uk/issu.../2447/page.pdf

RSB stands for Richard Samuel Brookman… R.S. Brookman & Co.
Looks like he had a partner (who didn't get his name on the door) and bought him out on the 16th March 1912.

Nice work! that might just be the clue that unlocks the mystery..

Here is Grace's Guide for R.S.Brookman. Note the reference to a 1967 patent?

http://www.gracesguide.co.uk/R._S._Brookman

That London Gazette, might not be the same Brookman, might be his father? That was in Middlesex, the 1930's RSB is in Leicestershire ?
