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 » 15 Oct 2019, 17:43

I sold my beloved pk recently so to cheer myself up I bought another one. The old one had really big tables and took up a lot of room in my shed. This one is normal sized.

Image

Its a rough old thing

Image

Image

This one dates from 1941

Image

Image

Image

Image

some one never believed in extraction

Image

Image

Im surprised the tilt and raise still worked

Its suffered some damage with a cast lug being knocked off. On later pk's this is attached with a hinge bolted on.

Image

I thought it would be safer to cut the pin then risk break the other lug, it took ages to hacksaw through with only an inch of blade stroke.

Image

78 years old and comes out pristine

Image

The part must of been put in place drilled and tapped and not moved

Image

Original paint under the tag

Image

First time I've seen witness marks on a wadkin

Image

To remove the handle just drill the peened over part and give it a wack

Image

Bondo time

Image

Image

Everything disassembled and in its own box

When you put all this filler on the main chassis casting are you making it better than new?

As in, is it just years of dings you are filling or are flaws in the casting the factory would have just left being filled too?

As always enjoying watching the dirty work with my hands still clean.

Its a bit of both, wadkin were very good at fettling raw castings and even early machines had a generous layer of filler before paint. On the lower portions of this its down to bare metal its had that many dings. On later machines I think they must of used some kind of spray filler because you find it on the smallest of parts, which would take far to long if applied by hand and sanded.
On older machines it was a black lead filler which if sound I leave as much as possible and just add to it. I'm going a bit over the top on this because I'm trying some new paint which is 5 times the price of my usual stuff so I want it to be as good as I can get.
The filler I'm using is a metal based filler which I find to be much better than car bodge.

This is the stuff I use for filling. Its a lot denser than normal filler plus I like the finish.

Image

wadkin on tiptoes

Image

Image

Lots of casting crud to remove

Image

Image

I thought I's treat myself to a new mop, not impressed. Its made from different types of recycled fabric. I cant imagine nylon is going to work on a mop

Image

Because I'm painting the base with the trunnion arms in place I thought I'd clean the bolts up first and then mask them off.

Image

A bit primer will help highlight any bits I've missed

I used to do it the old way of glueing some sandpaper to a board and doing each flat at a time, through the grits. I recently bought some Velcro stuff so stuck it on he little disc sander. Now I can give each flat a touch up and change the abranet quickly to the next grit

The handwheels are a bit crusty

Image

Stick it on the lathe spin and clean up with a flapper disc on a grinder

Image

Go through the grits

Image

Image

Image

The bone handles are rough but they clean up lovely

Image

Image

Image

Image

To fill in the bottom of the lettering I leant it over and used a 2 pack high build primer

Image

Image

Followed by top coat

Image

My spraying was not as good as I'd hoped

Image

I mixed too much 2pack paint so sprayed some drawers I had in my stash. I really like the bisley type drawers. These will be great for spindle moulder tooling.

Image

I went around the electric enclosure door wording with a Dremel

Image

I never had a spanner big enough for the but so stuck it in the vice

Image

And a big bar and stilsons to loosen it

Image

This was a bit disappointing, to get original SKF bearing is £25O

Love it Wallace! Love it. Shame about the bearing. What are you planning with that?

I'm sure you could get an alternative bearing at a better price. I think it is only the motor bearing and so not taking a huge load?

What are the key dimensions? I can look it up if you like?

Thanks Bob the spec is

RL16 - SKF Imperial Double Row Self Aligning - 2x4x13/16inch
I've found a modern equivalent which is NLJ2" for £14O. I also found one in Australia cheap but it has a designation of MRB.
I think it would be prudent to put a half decent bearing in because its a bit of a task taking the 35Okg table off to get to the motor :D

Simply bearings have one listed but not priced.
This one https://www.ebay.co.uk/itm/NLJ2-RL16-UL ... 4054323590 is £150 a but better than £250.

Not sure why they are using a self aligning bearing in a motor? Maybe to cope with less accurate machining of the castings.

Lots of single row deep groove options will fit too.

HTH

After much searching I found some replacement bearings, to get original spec for the big one was too expensive for my little wallet so I had to go for a pressed steal I did manage to get a Hoffman for the other end. £1OO for them both which I'm happy with.

Image

Image

The motor went together really easily with the bearings being a push fit.

I made some stuff shiny

Image

Image

I then got stuck into the frame that supports the sliding table.

Image

When it was first built, it was set up at the factory and each eccentric pin had a hole drilled to hold it in place. Assuming no ones swapped things around I should be able to put it back to factory spec.

Image

Image

The bearings are good quality but seized solid. Replacements are about £14 each so I will stick these in a bathe of evaporust and see what happens.

Image

The pins cleaned up ok

Image

There are 6 plane bearings which are used to adjust any lateral play in the slider. I'm surprized the pins aren't snapped because they are very hard and brittle with a very small eccentric head which the bearing runs on. You can also align the double mitre to the blade using these.

Image

Image

I presume this frame was planed

Image

Next up is the bit that holds the motor mount and pivots to achieve different cutting angles. Its quite a lump

Image

It had lost a hinge lug at some point

Image

I thought the easiest way to fix was to put a rod in and weld over the top and then drill the rod out

Image

Not pretty but a grinder and filler will fix that.

Image

It worked

Image

The fence is in good condition.

Image

To get the pins out you have to drag them out with a bolt. On later models the pin holes go all the way through so you can knock them out.

A bit more done, the column for the crown guard was a bit crusty and took a good 4 hrs to get to bits

Image

Image

Image

I think this is the first time a stud extractor has actually worked

Image

Image

Image

Everything got a coat of zinc primer followed by a coat of filler primer

Image

Then topcoat

Image

Image

This is for the slider carriage, its supposed to be brass coloured

Image

But it looks a bit West Coast Customs

Image

I picked up a nice catalogue recently which had this nice lump in it, 36" blade

So you are on the lookout for a 36" blade saw now?

:)

Enjoying the progress as always. Thanks for posting.
