    Default Wadkin RB Stand Type Buzzer

    What Not another Wadkin RB buzzer thread .

    Yes, one o the worlds great procrastinators (me ) is working on another buzzer. Another Wadkin buzzer. Another Wadkin RB buzzer. It's a form of avoidance - I'm avoiding finishing my other one, 'cause I can't make up my mind on a few things.

    Anyways - the cutterblock on my first buzzer had been abused and distorted, so I looked around for another cutterblock. I knew of an incomplete RB and made an offer.

    RB 501.jpg RB 110.jpg RB 111.jpg

    It's missing all electrical components, motor, motor pulley, belt guard, fence, cutter guard and all tags. I suspect a PO repainted it, and was going to convert it to single phase - but never got there.

    After a little negotiation, in November 2017 I went and picked it up. I couldn't just take the cutterblock - had to take the whole thing.

    RB 503.jpg

    Initially, I was only going to steal the cutterblock. The rest went into my rat hole.

    But over the intervening months a few things have come together. Bits began to escape from the rat hole and acquire a new coat of paint.

    I really must get around to painting out that blue (on the inside). The tags aren't original to this machine.

    Cheers, Vann.

    Default Parts - pt.1.

    In October last year I bought this seized wreck for $60, for parts.

    RB 504.jpg

    I think it's probably spent at least 10 years exposed to the damp New Zealand weather (along with three other radial arm saws).

    Here you can see the 1/2" rod that sits parallel to the arm, for positioning the travel stops. This shows the extent of the rust where the rod passes through the traveling carriage.

    RB 506.jpg

    In addition to a supply of knobs, Whitworth bolts, and a handwheel, this saw provided some parts suitable for a 2hp RB buzzer - including 2hp switchgear identical to this (but with contacts in better condition).

    RB 505.jpg

    And various tags and tag screws - including Earth tag, lubrication tag, wiring schematic tag, and a serial and test tag.

    Default Parts - pt.2.

    In January this year I came across this neglected Sagar under/over. I was told it was going to be scrapped.

    RB 510.jpg

    RB 509.jpg

    RB 508.jpg

    My second RB didn't have a fence, so I offered some money and became the owner of a rusty fence.

    The RB still has the bracket for its fence rod.

    RB 511.jpg

    My initial thoughts are to acquire a rod to fit the bracket, and mount an adaptor plate on the back of the Sagar fence. It would be a non-tilting fence. However, I brought home not just the fence casting, but also the tilt components and the rod, handwheel and bracket. If practical, I'll fit the lot. If not practical, it'll be back to plan A.

    This is getting close to a workable project.

    Cheers, Vann.

    Default Parts - pt.3.

    It'll need a motor. The CK radio alarm saw 2hp motor is probably munted (and doesn't have conventional mounts anyway).

    I have a Brooks 2.5hp motor that wouldn't look too out of place (the original motor would have been English Electric).

    RB 513.jpg RB 512.jpg

    The footprint isn't right - but an adaptor plate would rectify that.

    I very recently purchased this 2hp motor - but haven't taken delivery yet. If it's better suited, it might get the job of powering the RB.

    Default Parts - pt.4.

    It'll also need On/Off buttons.

    I acquired this off a damaged 1974 Wadkin CC.

    RB 516.jpg

    Now freed-up, cleaned-up and painted. It would have once been labelled "Wadkin Controls" but that lettering has long gone.

    RB 515.jpg I should have taken a better photo before it got dark .

    It's not the right era for this machine, but it'll do until something more appropriate comes along. At least it's a genuine Wadkin part .

    Cheers, Vann.

    Default What Era?

    So what is the right era?

    It had the second style of fence which appeared in the mid-1930s but was replaced by the RD style fence by 1950.

    A better indicator is the style of handwheel. The handwheels are spoked which makes it later than RB 519 of 1946. The handwheels are 5-spoke cast-iron, which I believe changed to 3-spoke aluminium in 1949.

    However I noted an even better indicator on the base. Early stands had no opening for the On/Off switch.

    RB 517.jpg RB 255 of ~1934.

    Later an opening was provided for the On/Off buttons.

    RB 518.jpg RB 418 of 1938.

    This flush opening was last seen on RB 567 of 1947. After that the base casting was modified to provide a raised rectangular boss for the On/Off buttons. Note that RB 563 (4 numbers earlier) has the raised boss - also note that RB 563 was tested later than RB 567 (maybe it's base was defective and they had to wait for one from the next, modified, batch?)

    RB 519.jpg RB 611 of 1948.

    In conclusion: the handwheels dictate that this RB is later than RB 519 of 1946, while the button opening indicates it's earlier than RB 563 of 1947.

    So this RB looks to have been numbered somewhere between 520 and ~567, and manufactured in 1946 or 1947 (as such, that 1946 CK tag isn't totally wrong ).

    Default Brookhirst.

    I completed and fitted the "Brookhirst" door today.

    RB 520.jpg

    The door is a particularly poor quality casting (maybe cast during WW2 for this 1946/47 machine?). On the left of the next two photos (taken some months ago) is the "Brookhirst" door off CK 1011 of 1946 - a very fine casting. On the right is the door off the RB.

    RB 521.jpg Note the ripples and voids in the RB door.

    RB 522.jpg Note the mounting bosses for the switchgear on the inside of each door.

    On the CK the switchgear spans almost the full width of the door. The RB has mountings for a narrow switchgear panel roughly half the width of the narrower door. The CK switchgear won't fit the RB door. I intend to mount it to the back wall of the switchgear compartment.

    Also note the standard "Brookhirst" door off the CK has a groove cast into it, around the inner edge. This is to mount a rope seal (to reduce dust entry). The RB door is simply machined flat around the inside edge. I've now glued a layer of cork to help seal against dust.

    Cheers, Vann.

    Default "Here's a Dish I Prepared Earlier."

    So with the base nearly finished, and my son coming round for tea, we lifted the base off the saw stools, and lifted the main casting and wedges onto the base.

    RB 523.jpg

    RB 524.jpg

    Then this morning I fitted the infeed and outfeed tables.

    RB 525.jpg

    RB 526.jpg

    And you may recall the Sagar fence I picked up in January. I positioned that on top as well, to see how it might fit.

    RB 508.jpg RB 528.jpg RB 529.jpg

    RB 527.jpg

    Still a long way to go. I'll have to design an adaptor bracket to fit that fence. I haven't started on the motor shelf, nor the motor - and I'll need to obtain a suitable double vee pulley for the motor. Then there's wiring, and the contactor (which needs all the contacts cleaned, then mounting). A blade guard, and pointers for the depth-of-cut scales. And numerous other small tasks.

    Cheers, Vann.

    I made up an adaptor bracket.

    RB 530.jpg RB 531.jpg RB 532.jpg

    It wasn't really designed, it just sort of grew. The angled plate is from a piece of 1/4" plate I had. The longer piece is 12mm bar - I needed the extra thickness as I wanted to tap the bar, as there is no room for a nut behind one of the two holes. Joining them was my first weld in maybe 18 years and the almost finished product involved a lot of grinding, and some filler .

    It fits on the fence like this:

    RB 533.jpg The bracket is in primer for this trial fitting.

    And the whole thing bolts together like this:

    RB 534.jpg All those bolts need to be shortened.

    You can see the reason for the angle here. I wanted the fence to go back as far as possible - and it allows the fence to go back to 1/4" from the back edge of the table.

    RB 535.jpg I've picked up the two existing holes for the original Wadkin fence bracket.

    In that position I get 9 1/2" inches of clear table.

    RB 536.jpg

    Not bad for a 9" buzzer .

    With the fence fully back the adjuster bar sticks out a long way. I don't know if I can afford that much wasted space behind the machine. With it adjusted fully forward (so that the table is fully covered) it still protrudes nearly 5" (it came off a ~16"-20" wide Sagar planer/thicknesser)

    RB 537.jpg RB 538.jpg

    As the narrowest timber I'll be buzzing will probably be in the region of 3/4", I think I'll be looking at shortening that bar by ~6".

    Cheers, Vann.

    Note: kindly excuse my use of imperial measurements - I've always felt that something designed in imperial should remain imperial, ever since I was given a job, shortly after metrification, that required cutouts at 914mm centres.
    So that's 914mm, then 1828mm, then.. umm... 2742mm, then... Hold on, if I flip the ruler over that's 3', 6', 9', 12' etc .

    Default Livery.

    The livery (or colour scheme) for this machine uses the appropriate grey - the lighter of the two Wadkin greys - RAL 7011. To break the all grey colour (even the machined surfaces dull to grey) I decided to pick out the handwheels in red (same colour as used on the raised "Wadkin" letters).

    I'm still not sure they're a good match .

    RB 527.jpg

    I used the same red on the handwheels of my (still incomplete) Wadkin LP - but being an earlier machine, the LP has the earlier darker grey, which doesn't look quite so clown-paint-ish .

    aLP 73.jpg

    And I spotted this Wadkin overhead router on ePay in the UK. It uses the lighter grey with red handwheels - and doesn't look right to me . Maybe I should have gone for black, like wallace does on his machines.

    RB 539.jpg

    Well I'm not going to repaint the handwheels now. Maybe later?

    Cheers, Vann.

    Default Fence Finale.

    I've painted the fence adaptor bracket - black. I looked through my meagre supply of random BSW bolts and found some 1" bolts and a single 1" bolt to use (rather than cut down the precious 2" genuine Wadkin-made bolts I'd used for the trial fitting).

    RB 536.jpg "BSW" How cool is that!

    I've seen metric bolts with an "M" on the head, but I think these are the first I've seen with "BSW". I painted them (black) to keep the dreaded rust at bay. I've recently tried blacking bolts by heating and dipping in oil. Unfortunately I threw out the old used car oil, but the results using clean oil just aren't as... black .

    I then assembled the adaptor bracket and the handwheel bracket.

    RB 531.jpg RB 530.jpg

    In the end I cut off 5" instead of 6". I'm not sure why - I guess I can cut more off later, but it's much harder to put some back on.

    RB 534.jpg

    It would have been nice to move the whole fence 2" towards the outfeed table to achieve this at the table lip...

    RB 533.jpg

    ...but that would have required moving the fence to here...

    RB 532.jpg

    ...which in turn would have required either drilling a new hole in the table (as the bracket would need to be cut away where the existing hole is), or loosing the use of an inch or two of table width. I'm not going to do either at this time. Lets see how it performs in service (whenever that happens ).

    And now - the fence, fully assembled.

    RB 535.jpg
    Well, fully assembled apart from that missing " bolt below the handwheel, and the clamping bolt that goes through the brass handle .

    Anyway, on to the next task.

    Cheers, Vann.
