The 'boat anchor' Waldown drill press
Hi all,
I picked this up last week or so as a fixer-upperer project. It is being referred to around here as 'the boat anchor'. It has no machine plates on it any more, and I can't find a serial number stamped anywhere either:
IMG_20200519_200404.jpg
It came semi-dismantled. I do have a motor - whether it is _the_ motor I am not sure - but I also see no year / sn on that either. I believe it to be a 5 speed as I have no intermediate pulley and (not knowing how they were mounted) there seems no place to mount one. The spindle pulley was just resting on top and also appears to be from some other machine - so, that might be a challenge. Oddly, the pulley is actually the same size as the one on the motor so it 'feels' like it should be the one - but it does not fit the splined spindle guide at all.
Gotta love that block of wood screw onto the handle there ....
The 'blue' bits (like the table) might also be from some other machine. Speaking of the table:
IMG_20200521_183420.jpg
.. it reminds of the Joker "why so serious" look. Geeeez.
I think it might be an 8SN series III, but I'm not sure. Any clues as to model and approx year range?
All help appreciated,
Greg.
PS - I have been through just about every Waldown thread I can find on this forum looking for info. I have seen RayG's and other restos. Good work there guys!

Sometimes the motors have the specs stamped into the casing, which is often quite shallow and can easily be hidden by a respray.

JS - thanks - no joy on that. I've been over the motor and nothing amazing there.
I thought I may as well show some resto progress and maybe ask some specific questions in separate post if need be.
An initial inspection showed the quill and spindle to have no play - so a good sign. What looks like wear on the front is very slight - you can hardly feel it with your fingernail. The spindle, at first sight, seemed good and the rack and pinion also seems fine.

The quill did not return though. The hand controls and depth indicator seemed in good order - albeit grubby/rusty. The quill spring is not broken, so I imagine maybe just not put back in correctly at some stage.

Paint is generally in poor nick.

The pulley situation is odd. The motor pulley seems to have lived its life on the motor, but, oddly, it is not keyed to the shaft. I do not know if this is actually the original motor ...
IMG_20200601_183221.jpgIMG_20200601_183224.jpg
The spindle pulley is just plain wrong and it also not keyed - I suspect it may be a middle pulley from a three pulley setup. But it sure ain’t the spindle pulley:
IMG_20200520_121437.jpgIMG_20200520_121445.jpgIMG_20200520_121530.jpg
The only two identifying marks I see are under the table - and behind the motor mount. I don’t know if either of them is original, but the motor mount is at least the same colour as other stuff, so it probably is.
IMG_20200527_182814.jpgIMG_20200528_130110.jpg
The shaft is pitted and fairly grubby and rusted. It took some effort to get it out of the stand - it was rusted in. But I got it on the lathe and hit it with sandpaper of ever-smaller grits to get something decent.
IMG_20200531_105859.jpg
It is a little bent, so may need some straightening.
We had two good days of weather at the weekend just passed so I figured I get in a couple of big days to strip what I could back to metal, prep it, and get it painted. Paint is dulux industrial enamel. Colour is “Jimbaran Bay” - I got that tip from another post in this forum that said it was close to a mix of that and some other colour. I just went for the Jimbaran Bay and it seems good. I have to say the castings are amazing quality.

Looking a little more decent now.

The top box paint was very stuck on and the rust patina was like welded to the surface so even with some wire wheel grunt it was hard going. I figured I’d just dump it into a small electrolysis tub and let it stew at 2-3 amps. Getting results.
IMG_20200601_195003.jpgIMG_20200601_194018.jpg
The spindle MT2 section is pretty beat up (understatement) , so at close of play today I went to skim a couple of thou from the outside to clean it up a little and …sadly, it is pretty badly bent. Like about 0.5mm just in the MT2 section.
IMG_20200601_185821.jpg
Ouch. Will stew on that for a bit. Happy, all bearings feel fine.
I did score myself a 13" D1-5 face plate that I was figuring I might turn into a table with some as-yet-unknown mounting arrangement:
IMG_20200530_153645.jpg
Time to go and flip the top box in the electrolysis bath. Later.
Greg.

Looks like some good progress there.
Unfortunate about the runout in the MT2 taper, though :/

We have the bench version of what I'm pretty sure is the same machine at work and it has 4-step pulleys, not 5 like yours. 8SN sounds familiar, I'll try to remember to check the plate tomorrow.

Yep, Type 8 SN Series III. The 4 speeds are 470, 1000, 1830 and 3950 RPM with a 1450 RPM motor.

Hah! Righto. Thanks for that. Unless they also made a 5 speed looks like maybe I have a different motor and pulleys.
Well, keeps life interesting eh!
Thanks again for that. Kind of you to have a look.
Greg.

Hi all,
I had a go at straightening the spindle to see if I can get it back into action.
Introducing my very expensive straight-o-meter. Some angle iron with holes in it held in the vice and a few aluminium pieces - a 'stop' and two 'v' pieces.
IMG_20200602_184838.jpg
It works very well. Get a bar on it and see where the greatest bend is. Try some variations of where the V's sit to get an understanding. The Mt2 section is beat up so I burr-filed that back to make it smooth-ish again so it'd ride in a V.
Process is: mark a high spot, get it on the shop press. Bend it some. Check. Repeat about 100 times. Have a cold lager. Here is the press setup using two small V blocks. I machined a 'collar' for the shaft side that was same diameter as MT2 section so it'd all sit flat in the v blocks.
IMG_20200602_193323.jpg
To get a different view on it, I also chucked it up in the lathe. When I made the chuck backplate I gave it some play on the register so I can loosen the screws and tap things true in it. "the poor man's adjust tru". This made it easy to get out, bend, put back in, tap true in about 5 seconds, then re check.
IMG_20200603_183519.jpg
The spindle is a bit mysterious - it seems the outer of the Mt2 section may not be true to the mt2 bore. I think it may have got a skim on a lathe some time and was already bent. On the straight-o-meter I have the bend down from about 0.55mm to about 0.01mm now (with the indicator inside the bore), but putting an arbor in there gives me a few thou runout. So kind of confusing - I've even run an Mt2 reamer in it to lose any high spots. But, the 0.01mm thing is progress of some sort.
I think I'll just get it in the quill and mount it and measure it in situ. If it is sh*te sh*te sh*te, then I'll learn how to make a new spindle I guess.
In other news, the top box has finished its series of dip-then-wire-brush sessions in the electrolysis bath and I've hit it with the wire cup wheel. Shown here fully naked sitting atop:

I think they're cool. They look like an art deco train, or the rocketeer's helmet or something.

Hi Greg,
I somehow clicked on 'wants more pictures' in your initial post. Ignore the request.
Nice to see another Waldown being rescued and resuscitated! Before I acquired my 3M drill a succession of clowns had attempted to chain drill the table in half.

I couldn't live with it so I purchased a new table from Waldown. Fifteen or so years ago they were affordable.

Hi Bob, nice to hear from you - I hope you and the fam are well mate.
Re the table - our units must have been used at the same TAFE or something. )
I priced a Brobo table yesterday, they were $385 + GST. But, I have a lead on one that may be in better nick. Fingers crossed!
Hopefully tonight I am off to measure up the pulleys on a working specimen. After that I'll make a plan as to whether to try to use the two I have to make a 5 speed model (though with a thinner belt I imagine), or make a couple of four speed jobbies anew. We'll see. I also have a feeling that ultimately I might be up for making a new spindle as well - time will tell. I did ask Brobo about replacement spindles - they have none.
As it is also missing the machine plates, I'll have to work up how I make those as well - been watching a lot of vids on that.
Hey, would you have the faintest ideas what year range this might be?
Greg.

Hi Greg,
All is well over here. Isolation works for me!
I would imagine early sixties for your 8SN. At some stage Waldown modified the return spring housing making it larger and graduated. The 2M, 3M and 8SN all shared the same revised housing.

Here's a link to some Waldown history that should prove interesting if you have not yet chanced upon it - https://motofaction.org/tool-reviews...y-information/

It is obviously different and the fixing hole locations are closer together than the original but it's yours if you want it Greg.

Thanks Bob - that sure is a very nice machine you have there. Thanks for pics. What approx year is yours?
I note the dual quill adjustment nuts, and also the placement of the power switch and altered motor mounting arrangement.
I had a feeling (in my bones) mine might be an earlier example. The return spring housing on mine is the older type you mention for sure.
The small hole above that housing is an oil hole I imagine? Mine also has one front and center on the quill housing, so I was figuring it'd be for oil.
Is that block on your spindle stock? MT2? Maybe for some greater rotating mass or something?
Thanks again,
Greg.
PS re the link to history: yep I did find that one!
