Thread: Wadkin RB Buzzer

Hello Vann, what's your opinion on the old style fence slide as apposed to the more traditional rack and pinion

I have insufficient experience with either to give you a knowledgable answer. However...

Both my Wadkin PK saw and my Wadkin RB buzzer have fences that slide in dovetail grooves. It's a bit clunky. In the case of the PK dimension saw, there is a micro-adjuster that gives the accuracy needed once the slide is locked down (the micro-adjuster is a pleasure to use). In the case of the RB the "clunkiness" doesn't affect anything as precision is not required.

The Rev. Forsberg (the High Priest) has the rack and pinion on his RM planer/thicknesser, and has it running freely so that he can almost spin the handwheel for easy adjustment. He's said he's looking to acquire an RB - but a later model with the rack and pinion. He obviously thinks they're sufficiently superior in use to be worth waiting for (but then again he's the High Priest, so his Wadkins have to be of the highest standard ).

I want to true up my timber and either fence will allow that with the same accuracy. Being a weekend woodworker, I don't see myself using my buzzer enough for the sliding adjustment to become a nuisance. If I used my machine on a daily basis, maybe I would find the handwheel adjustment sufficiently superior (if I could find one at a suitable price).

HTH.

Cheers, Vann.

Not a lot of RB buzzers on the market in recent times, but here's one that showed up in England.

RB 519a.jpg

RB 519, test 27047, of 1946.

wRB 519 27047 UK.jpg

Note the second type of fence, and the second (knobbed) type of handwheel (for adjusting table height). Also the narrow "Brookhirst" door.

Finally the motor: a 2850rpm, 2hp motor by English Electric.

Cheers, Vann.

It's been a long time (nearly a year) since I updated this thread. Then again it's been along time since another RB showed up.

This one is from the UK. It's the first RBD to show up - the 'D' indicates it was built as a DC powered machine.

212a.jpg

Now sporting a modern (finned) AC motor.

212b.jpg

Note the second type of fence... (the lowest numbered RB with this type of fence - so far).

212d.jpg

And the first type of main casting, with arch... (the highest numbered RB with this feature - so far).

212g.jpg

It has the second type of handwheel - solid (not spoked) cast iron.

212c.jpg

Also note the earlier stand - without a built-in electrical cabinet.

212h.jpg No "Brookhirst" door.

It has the standard, 3 stud 'clamshell" cutterblock fitted to all Wadkin RB buzzers.

212e.jpg

And the additional 2 stud "clamshells" for moulding knives (not fitted to the first dozen RB buzzers at least)

212f.jpg

RBD 212, test 700, of ???

wRBD 212 700 UK.jpg Lowest test numbered RB tag (so far).

During the past year new information has come to light, on the Test numbering of earlier Wadkin machines (pre 1939).

Just a few years ago we thought maybe the first two digits of the test number was the year of manufacture (even though it was obviously wrong in places). Then someone (wallace?) got hold of the test numbers for each year (from 1938 on anyway).

We thought that maybe the machine serial numbers started at 100 or 101, then someone (Jack?) heard from an old Wadkin employee that they started most series at 105 and (with the exception of MNs) that seems to be true.

I've noticed some anomalies in the test numbers. My own RB for example, is one of the first produced, being RB 116 (of 1925) with test number 4374. Two obviously later models: RBV 231 and RBV 255 have earlier test numbers (1041 and 2359 respectively). I asked at AMS about test number 1041 and initially they couldn't find it.

Two machines with the same test number !!! And neither of them the one I asked after. I checked the number and it was definitely correct.

wRBV 231 1041.jpg RBV 231, test 1041.

Does that mean there were three machines with the same test number? Yes apparently...

Originally Posted by AMS

After they started they used test numbers up 9000+. This sequence went on until circa 1930. The machine with number 1041 in this sequence was MB 357 in 1923.

They then started again at test number 1000 in 1931 and used this new sequence until 1938 when they appear to have just stopped. The machine with test number 1041 in this new sequences was AZA 159 in 1931.

At the same time they restarted with the second sequence at 1000 they also started a new sequence beginning back at number 1 in 1931 and continued this third sequence until they finally closed down in 2009. It is this third and final sequence that included RBV 231 as test number 1041 in 1932.

So it would seem that any machine prior to 1938 could be numbered in one of three sequences. That explains why there are Wadkin Ltd tags in amongst the Wadkin & Co. tags - different sequences.

This machine is obviously newer than my RB (test 4374) of 1926 - so it can't be numbered in the first sequence. The test number (test 700) is lower than 1000, so it can't be numbered in the second sequence. It's therefore the 700th machine tested in the 3rd sequence, started in 1931.

As RBV 231 is also from the 3rd sequence, and was tested in 1932, I conclude that RBD 212 was tested after the start of the 3rd sequence in 1931, but before Test 1041 of 1932.

So here is an updated and revised list of the 35 Wadkin RB buzzers identified so far.

RB 109, test 4359, Oct. 1926 - New Zealand (RIP in 1987);

RB 745, test 35560, of 1950 - United Kingdom - Wadkin Ltd. tin tag;
RB 793, test 38322, of 1950 - United Kingdom - Wadkin Ltd. tin tag;
RB 830, test 39773, of 1951 - United Kingdom - Wadkin Ltd. cast tag;
RB 839, test 41647, of 1952 - New Zealand - Wadkin Ltd. cast tag;
RB 876, test 42337, of 1952 - New Zealand - Wadkin Ltd. cast tag;

RB 1024, test 50316, of 1954 - New Zealand - Wadkin Ltd. cast tag.

It looks like RBA 158, RBA 183, RB 190 and RB 193 - previously thought to be from 1937 & 1938 - are actually earlier machines from the 1st sequence - based on their Wadkin & Co. (pre-1936) tags

Cheers, Vann.

Amazing research Vann . A single one has not turned up in Australia ?

Okay, info in from AMS:

RBA 158, test 8623, of September, 1930, - United Kingdom - Wadkin & Co. cast tag;
RBA 183, test 9335, of May, 1931, - United Kingdom - Wadkin & Co. cast tag;

RBD 212, test 700, of July, 1932 - United Kingdom - Wadkin & Co. cast tag;

Cheers, Vann.

That makes my brain hurt

Cheers, Vann.

Wallace this week sent me some photos of an RB he's just acquired.

RB 356.jpg
Looks like the cutterblock guard has been given a hard knock , bending the supporting shaft - lets hope there's no other damage.

It's a early-ish machine, from the Wadkin & Co. era - RB 256, test 2360.

wRB 256 2360 UK.jpg

As both the serial number and the test number are one higher than RBV 255 of 1934, I think it's reasonable to presume that this buzzer also dates to 1934.

Note the second type of fence...

RB 358.jpg

...and the second (knobbed) type of handwheel.

RB 359.jpg

No "Brookhirst" door on this one, just the rounded opening at the back, matching the one at the front of the stand.

RB 357.jpg

Also note that there's no opening in the side of the stand for the On/Off buttons. All the electrics were external on these early machines.

RB 360.jpg

And finally the motor: a big ugly single-phase beast. Wallace says it appears to have been single-phase from the factory - the first single phase RB listed.

Way back on page 3 of this thread I wrote:

Then on 2^nd September, 1925, they added a late specification, No.101, for the supply of 12 Bench Planers - High Speed. For some reason the Prime Minister specifically requested that The Luton Tool Company (Luton, UK) be asked to tender.

Attachment 413816 This appears to have been signed by the Prime Minister ...

Well, I'd never heard of The Luton Tool Company, so when this "bench" buzzer showed up recently, I thought I'd record it for posterity - or as a comparison with Wadkin.

Luton1.jpg

Note that this is a 6" model - more comparable with Wadkin's 6" RA than the 9" RB. I assume Luton also made an 8" or 9" model.

Luton2.jpg

Luton3.jpg Luton4.jpg

Luton5.jpg Steel lips (good), but no skewed knives (not so good).

Interestingly, I could find no reference to The Luton Tool Company on the Vintage Machinery site, and plenty of references to "Luton", but none to The Luton Tool Company on Grace's Guide either. Must have been a small company.

Cheers, Vann.

A rather rusty specimen to add to the database.

RB4a.jpg

RB4b.jpg

It's a early Wadkin Ltd. machine - RB 409, test 9969 - of 1938.

wRB 409 9969 UK.jpg

This machine is different as it's flat-belt driven. I knew that lineshaft drive was an option but this is the first flat-belt driven RB seen. Note the flat pulley on the end of the cutterblock spindle - and the lack of electrical information on the tag.

RB4p.jpg

The previous RB in the list is Wallace's recent rebuild - RBV 256 of 1934...

Originally Posted by Vann

Like both of those machines this has the second type of fence...

RB4fe.jpg

...and the second (knobbed) type of handwheel.

RB4k.jpg

But when it comes to the base casting this one shows a few changes since RB 256. They've added an opening for On/Off push-buttons under the infeed table (and then blanked the opening, as this has no electrics). And they've deleted the rounded opening at the back, adding a switchgear compartment with a full size "Brookhirst" door (presumably empty as no electrics). Some later RBs had a narrower "Brookhirst" door.
