Kryn, Pipeclay. Can you please move your conversation to PM's or marketplace. Thanks.

I did a quick re-assembly of the quill and spindle to check runout and bearing play. I am happy to report the quill spring is fine and the quill is a perfect fit in the housing with zero play - even without tightening the adjustment nut. You just have to love well made machinery. Happy about that.
After trial assembly, and using an MT2 alignment bar:

I get about 0.006" at 30cm from spindle 'root'. While not too bad, and certainly better than it was, it is not yet good enough - so some more straightening required. At least it likely means I will not have to make a new spindle ... which I am both happy and sad about at the same time. )
Additionally, although the existing spindle bearings felt fine when turned manually, when installed and measured there is just way too much slop. I'll be replacing those. Hopefully they are dead nuts on the same size as the current ones as it looks like Waldown shimmed things to perfection at factory. Here is the deal: there are shims between bearings, and shims at end of bearings to contain them between circlips. Phew.

SORRY about the O/T comments.
That's a sure sign of quality, I'll bet you won't find shims like that on Chinese made drill presses.
Could the "0.006" at 30cm from spindle 'root'." come from "way too much slop" in the bearings???

Hi Kryn: Thanks. I am pretty sure that the runout there comes from the bent spindle. I'll get new bearings in and we'll see. I'll be aiming for less than half of that - but that might take quite some patience!
Joe: I have found this: https://www.woodworkforums.com/f65/p...61#post1753161. Very cool! And also Bob's pics of the mount here: https://www.woodworkforums.com/f65/w...-photos-181817.
Good info. I had wondered how it might be mounted. For sure, the 5-step pulleys I have are not like any I have seen in pics here, but they might still do. If all works out, the intermediate pulley will be a great thing to do. The motor might want to be more than a 1/2 hp though (?). According some docs kindly supplied by Anorak Bob, Waldown had 3/4 hp for three pulley models.
But "make it work, then make it work better". I'll be aiming to get it operational first!

Eric, if Bob's already sent it, I'll do that for you. Bob, if you've already sent it you should have been nursing that back instead .. and _not_ sent it!! )

Greg and Eric,
The Waldown name plate has not yet been posted due to a hindrance of mobility and I do not have ready access to a scanner. When Greg does receive the plate, maybe it could be used as a starting point to photoshop (or whatever) a version of the plate affixed to the 8SN and the 2/3M.
Greg, I took this snapshot for you yesterday of the badge that is missing from your drill.

Bob, thank you - and no rush for the plate. Rest up. I'll do scanning or whatever.
Re the side plate. Thanks. Though, if quite an early model I am wondering if it should be one of these?

I'm not sure when the 8SN 'rectangular' one came in (nor when the pressed steel top box came in). This is an 8SN series II (it seems) with no top box .. and the rectangular tag:

I guess there must have been a time when it was just an 8SN .. and no series II or III. ... maybe they had the oval tag.

Greg,
Just to add to the uncertainty regarding vintage, here are some photos I snapped back in 2012 while visiting Melbourne of an 8SN owned by joiner extraordinaire, Matty Fazio ( 'L. S. Barker1970' on the Woodworking Forum ). It shares the same motor mount / switch casting as the 'anchor'.

Thanks Bob. )
That one looks later than the anchor and still have the 'art deco' front tag. Nice.
And just to throw in a little more confusion. The 'rounded vs angular' quill adjustment 'nose' in the head casting. Seems they had two sorts and I thought maybe one predated the other, but here is both in the same in the same brochure on the same page. Mine is the rounded type which 'feels' earlier - because they are angular even now. But who knows.

Also, at some stage the motor mount arms were secured by top nuts to the motor mount plate - but mine are pressed in (no securing nuts at all) - don't know which might be earlier, but granted one of mine is loose that might indicate they later secured them with nuts to stop that happening.

Mysteries eh.

Oh, and I forgot the other thing ... no pinch bolt for fixing the head to the column - it is secured by two grubs screws at the rear of the head. The anchor does not have this:

Hi Bob - fyi, I received an email last night saying you had posted here with some attachments, but the message does not seems to be here. A glitch somewhere perhaps.

Not a glitch Greg.
I deleted the post because I thought it had no place in your thread. I reposted the photos in the general forum though they well may be of interest to only you and me - https://metalworkforums.com/f65/t205...46#post1969746

Progress update. I've posted on another thread looking for the dimensions of 9 speed 8SN pulleys here: https://metalworkforums.com/f65/t205...ley-dimensions
Let's hope that catches a fish.
In my hoarder's collection of bakelite knobs I had some of suitable size, but incorrect thread, so I re-did those to fit:
IMG_20200607_091143.jpg IMG_20200607_091608.jpgIMG_20200607_101007.jpg
Lookin' good.
I also gave the spindle some more attention. I was measuring swapping between a MT2 test bar and a taiwan keyless chuck with some HSS rod. Some further hours of dicking about got it down to about 0.003" - so a good starting point. I might see how we go with that.
IMG_20200607_182313.jpg IMG_20200607_170842.jpg
The lid, motor and motor mount and other gubbins have all been prepped and painted, motor with new bearings etc. I had to do maybe three coats of putty primer and sandback on the lid to fill the pitting.

so, all going kind of okay. Then ...
IMG_20200615_175049.jpgIMG_20200615_175055.jpg
The sodding motor/mount doesn't fit! The mount interferes with the top box such that the mounting 'arms' hardly go into the head at all. Doh!!
I guess I had just kind of _assumed_ it would all be okay given the motor was an appropriate size, the right brand, the mounting holes all lined up, it was a waldown-ish colour. I did kind of suspect it was maybe a later motor and likely not original. But .. doh!!
Righto then. The 'anchor' is offering up some resistance here to re-entering the workforce.
So ... pulley dimensions sought, and, despite having a few motors about, none are correct, so I'll need to track down a suitable motor as well - hopefully I can find something 'period correct' ... ish ..... and maybe go for 1hp rather than 1/2hp. Let's see.
In the meantime, I've been looking into how to recreate the original tags. I have the sn# plate off the bridgeport to redo and also one from the shaper that needs replacing, so might be time to sort how to do that, Plenty of vids about so should be okay - except for the part where I do the artwork ...
Greg.
