Wadkin PK Ripping Fence
Hi all. Now that my Preston bandsaw is usable (not finished, but usable ) I'm beginning to look at getting the Wadkin PK up and running.
The saw itself is still in the rathole. The saw is not getting a full overhaul, merely a de-rust, and freeing up of of as much as I can (without dismantling the saw), with the odd bit of new paint to keep further rust at bay. The crown guard, arms and stand were nearly finished when it got consigned to the rathole. As was the sliding table, and the double mitre fence was progressing. The biggest outstanding job is the ripping fence.
So last week I dug out the fence, and disassembled it, followed by removing the remains of a repaint, and a general derust.
F1.jpg The best photo I've got of the fence as found (taken a few days before the saw was purchased in July 2015).
F3.jpg Partially disassembled (last week).
The fence is in reasonable condition. A bit battered, but not horribly so. The taper pin through the collar of the micro-adjuster is bent and will be replaced (a ♯3 x 1½” long), and one of the four grub screws for aligning the fence plate is missing.
Also, the base casting of the fence has a bolt that is damaged, and I'm not sure what it's supposed to do...
F2.jpg F5.jpg The bolt head - posed for this photo today.
Turning the casting over, the stem of the bolt extends into the dovetail groove in the table.

The hole in the casting is tapped (⅜"x 16tpi = ⅜" BSW) so the nut functions as a lock-nut. The bolt is bent...

... and the end looks like it's broken off.

Anyone know?

A User Mod?
I've search far and wide for pictures of details of the PK fence. The best pictures I've found so far are in Auscab's thread on CWW "A Wadkin PK in my back yard" https://forum.canadianwoodworking.co...ack-yard/page2
fetch-3.jpg fetch-2.jpg Jacob's fence off PK 1947 (of 1956), the fence on the right in each photo belongs to Auscab (and does not appear to be made by Wadkin).
There's no sign of that bolt, so I'm no wiser. Maybe it's a user modification - but for what purpose? The bolt extends into the dovetail groove, but is too narrow to be a guide, therefore I presume it had a dovetail end to lock the fence mechanism. But it is threaded in the casting, so a dovetail couldn't be tightened .

Keyway
Looking further at Jacob's fence base, I see that his has two screwed-on keys that engage in the dovetail slot, to keep the fence aligned.

On my fence the "keys" are part of the casting - and are well worn.

I might have to consider having a slot machined and fitting bronze keys, as fitted by Matt Matt and described in his CWW thread "What A Wadkin PK Great Day" https://forum.canadianwoodworking.co...eat-day/page30 (don't try reading the whole thread unless you've got a week free )

Hi Vann.
What year is your saw ? The fence has the same PJ32 pattern stamp that is on my early saw .
Ill see if I can get a pic of my early fence . I don't remember a bolt being there though . Why is it sticking out in the under side direction ? The fence wont go on if its there of course. Could it be a user mod pre set sort of stop . so you could loosen and tilt the fence to the set up angle which stopped on the end of the bolt ?
One thing I wonder about the tilting fence on the PK is, Why have it ?? The tilt fence option.
The blade tilts and is much better and safer to do angled cuts with the blade tilted and not the fence.
Could it be because Wadkin used the saw fence from the PJ Saw and that never had tilt blade ? and they stuck with it ?

My guess would be like you said a user mod to try and fix the worn keyway on the base. The keyway stops any slop in the fence. Your fence is from an early saw but has a fine adjuster knob like the later fences. The two pins that the fence pivots on are fun getting out, on the later fences the dowel goes all of the way through so can be knocked out. On yours they have a threaded hole that you can use a bolt to wind them out.

Just to clarify: it's a worn cast key, rather than the keyway (I haven't checked the dovetail keyway for wear yet).
Auscab, thanks for the photos. Just looking at the differences:
- the micro-adjustment knob is turned steel, not cast (like a G1 PK);
- the four screws to align the fence plate are bolts wit locking nuts (on mine they're 1/2" x 1/2" Allen screws with a fine thread - 19tpi );
- the sliding tee handle to adjust the fence plate (mine just has a nut). I see in the "A Wadkin PK in my back yard" thread, that Jacob's PK fence has a small ball lever handle in this location;
- also in the "A Wadkin PK in my back yard" thread, I see that both your other PK fence, and Jacob's PK fence, have sliding tee handles to adjust the fence angle (to 45*) whereas I have a nut there too. So this is missing from mine.
But back to my bent bolt - I think it's safe to conclude that the bolt is a user mod - and can be dispensed with. I'll have to try the fence base in the dovetail keyway to see if replacement keys are required.

Isn't that knob on my last fence pics , from PKA 390 a G1 knob?
I only know of two knob types and I thought this was the early one . Same as the UK PKA 266 I thought, but there is only an end shot of that.

left is PKA 405 AU. And right is PKA 266 UK

Knobs and Handles.
Yeah my bad. I remembered (badly) that the knurled steel knob (1st type) was only found on G1 PKs, but having just checked the type study I see it is also on G2 PKs.
I've just finished trawling through photos of ~32 different PKs (yeah I know - I need to get a life...), about 20 of which showed some detail of the fence. The most common arrangement of handles and nuts is this:
PK97.jpg PK 1479 of 1952.
Only three or four had a different combination. So might look at getting another sliding tee handle made up.
