Wadkin PK restoration

Here's the place to talk about all your table saws, bandsaws, routers and dust extractors. In fact anything that makes noise and uses electrickery.

Wadkin PK restoration

Postby wallace » 12 Jan 2022, 18:30

Since I finished the bandsaw yesterday I thought I'd crack on and start this thing. I got a message a couple of years ago asking if I knew of any history to it. All I knew was that it was an early generation 1 machine. Oh and I wants it.

I offered to buy it but he was not ready to sell it. But he did say if and when he would contact me. Going forward I messaged him every few months to see if it was for sale and eventually he must of got sick of me asking so he offered it. The price was high, twice as much as I knew I could buy one for elsewhere. But like I said earlier 'I wants it'.



His place was not suitable for pallet collection so I drove to halifax and put it in my VW. I remember it well because after I'd loaded up and secured everything I had a little rest and had some food and coffee. It was then I saw a middle aged woman saunter up to my window and ask, 'do ye fancy any business luv' in a very yorkshire accent. I declined but did offer her a butty, she looked knackered.



Anyway I digress, I've been looking forward to this one for ages.

Do you see the 115 stamped after the PK, that is what number it is but wadkin started at 100 so my machine is the 6th machine built.



Image



It was built on 13th sept 1928



Image



It was overhauled 4 years later and it looks like the speed was changed. Can you imagine a machine nowadays being tested for 6hrs.



The thing that floats my boat is that the PK was unveiled to the public at the 1928 trade exhibition, maybe this is my machine.

Image



This is the first time I've done a generation 1 and their are lots of modifications on later machines



Image



Image



The ruler is etched into the table, later a chesterman ruler was inset



Image



These bolts are for extensions to acomodate a longer slider



Image



Image



Image



Image



Image



Its had alot of work done to it at some point, it has a modern dc break and a crown guard from a much later PP



Image



Back in the day this is what was in use



Image



I cant imagine why the PK took off

Nice.

I'm already enjoying the 'spot-the-difference' with later models.

Yours was only the second PK built as an AC powered machine - PKs 105 to 113 having been built as DC machines (230v or 460v) although several of those were modified to AC before leaving the factory. I guess even back then DC was loosing popularity.

Cheers, Vann.

This one is going to be a good one, do you have a matching crown guard or are you going to keep the one off the PP on it?

The P.J. is an interesting one, I've don't think I've seen a table saw with a tilting table in use, must be very awkward to use when tilted with the weight of the timber bearing into the blade thanks to gravity.

Vann I knew you would like this one, dont you have a tag picture of an earlier machine.

Trevannion, I have a crown guard off a AX but I think it has the mounting hole diagnally and not right angles, I also have a nice brass crown off a big rip saw bench but that is meant for a 30" blade so no use. Ideally I would like a wadkin & Co crown guard.

I actually have one of those PJ machines I got it from a really old foundry in blackburn. The sad bit is its had its double arbor mechanism removed. It has some crappy pillow block bearings with a spindle holding a metal cut off disc. It was being used to cut off sprues on castings.
Can you imagine doing a 45 degree rip on the thing

I made a mistake in my earlier post this machine was the 11th made and wadkins machine numbering starts at 105. Thanks to Vann the wadkin statistician.



Wadkin added flip top oilers on later models here for the raise and lower shaft.



Image



I find you dont need much heat to free up stuck pins



Image



Image



This has definately been taken to bits in the past. The tapered pin has been wacked in too hard. I had to drill it out.



Image



Image



The grease nipple has been rubbing when tilted



Image



Image



I found a broken stud which someone has attempted to drill out not so well. I wont be able to drill it out so might try the doubleboost method of welding a nut on it.



Image



Now this is a bit odd, this is where the gear for the tilt is attached,



Image



Its almost as if someone messed up the pattern for the base casting, and forgot to add a hole and a raised area that would normally be machined flat for bolt holes.



Image



Image



And this part has been cobbled together, the bit where the shaft goes through is nicely bored with oil grooves inside, but there is thick steel welded on the sides for the bolt holes.

Hi wallace. I have a picture of the tag off PK 110 (in Scotland) and of the test page.

wPK 110 6150 Scot.jpg
(456.7 KiB)
PK 110 test 6150.jpg
Tested 24th July, 1928 - 20 days before PK 115.
(493.24 KiB)

After seeing that mess they made with the tilt gear on PK 115...
PK 115b.jpg
(108.69 KiB)
... I tried to blow up the only photo I have of that part of PK 110.
PK 110a.jpg
(131.3 KiB)
As far as I can make out, PK 110 has a cast boss there. That would suggest the 'bodge' on PK 115 is not a modification to early PKs - but a machining cock-up specific to PK 115 (if I'm seeing the detail correctly with these old eyes :eusa-shifty: )

Cheers, Vann.

That makes sense especially the way the section is drilled out of the main casting. Someone probably screwed up the machining and it had to be bodged.

Ive been removing the old paint mainly at the bottom where it was really chipped, theres no point removing every bit because the filler they used is really solid.



Image



Image



Followed by a load of aluminium filler



Image



I've done quite a few PK's and never thought to put the casting on a bench to work on.



Image



Wadkin would stamp parts with the machine number to keep them with the correct machine. Looks like someone picked up the wrong bit.



Image



This part is off an earlier version



Image



This poor thing has certainly been in the wars, the fence plate has been welded and re machined



Image



Also the blade flask has been snapped and welded back together



Image



Image



A later version of the trunnion

There's some great restoration channels on Youtube, but none of them are as good as this......

Hmmm. I suppose you could pick up a better condition fence plate off a later machine, but I guess most of the other battle scars you'll have to live with.

I can't tell, is the blade flask aluminium or cast iron/brass?

Cheers, Vann.

:oops:

I saw one of someone restoring an old adjustable wrench which had over a million views and people gushing about how fantastic it was. It was ok but nothing grand. :D

Vann whoever did the repair on the fence plate did a great job, it must of been done properly with cast iron rods because you cant see the repair on the other side. Normally people use nickel rods or braze which sticks out like a sore thumb.
The blade flask is aluminium, and quite crude compared to the gen 4 ones, I was going to shine it up but I'm not so sure. It is quite distorted by the welding
