Oh I had stuffed up the post above showing the "key" - so here it is - a little loose rectangle of steel that locks the cog onto the axle

Its a long old job - particularly when I lack all mechanical skill 
Hopefully it'll get there in the end though!

Sorry to be an engineering pedant, but a woodruff key is semicircular shaped. A plain rectangular one as far as I recall doesn't have a specific name other than 'key'.A great "Lazarus" thread and an interesting read............I think the little key is properly known as a Woodruff key
I'll do a longer post when I have the time - but I got a finish coat of varnish on the table top today so I thought we would have our first "before and after" shot

On an allied subject, does anyone know the proper name for the thing at the bottom left in this picture?

Its a round collar with a grub screw that slides over a pivot to hold things in place. Feels like it should have a fancy term!

Well I started today off with completing the stripping of the parts I broke down earlier in the week and then got a first sprayed coat of metal paint on them

I then hit a point where I needed to continue the disassembly. This meant breaking down the frame of the mangle. So I needed the big socket set

Step 8 - Disassembling the Mangle Frame
Having got all smug about having the large sockets - it was inevitable that the first nut I tried to remove from the axle / pivot that allows the mangle to rotate beneath the table, I had no socket to fit
I do however have a very large adjustable spanner. I don't need it often - but I'm glad to have it when I do

Having been pleased with myself on that score, the nut on the other end of the pivot was completely siezed. I broke out the blow torch to loosen it - and was careful not to be smug. I'm not sure if it was burning paint, shifting rust or expanding the metal that released the nut, but release it did.

Having got the outer bolt off - I noticed there is also an inner nut

Even with both nuts removed, I could not slide out the pivot - there were collars with grub screws at each end of the pivot preventing it from sliding in either direction. You can see the collar at the bottom right

The grub screw had a weird square head - but fortunately a pair of mole grips released it

Even with the collars released, the axle was held in place by the end panels of the mangle frame. So I decided to remove the other bars holding the two sides together.

First I pulled the cotter pin and took off the upper cog

The "Oil" lubrication spot made me smile - its been a long time since this saw any oil!

Having removed that, I unbolted the catch that secures the mangle assembly and prevents it from turning down under the table

Having removed the catch, there was still a cross member holding the two sides together

I unbolted this

Then I took the big cast iron stretcher off the bottom

Only the pivot secured the two sides now. There was also a strannge bolt shown centrally locking the cog against the frame side

I removed this

I then found that this cog was actually threaded onto the axle - a vice was needed to remove it

That removed the last of the small parts

and the large parts were fully broken down for stripping and re-finishing

So there we are - the whole mangle is now broken down into the individual cast pieces. I will need to take a while now to strip, clean and re-finish each part. Then we can see if all these photos and notes helps me put it back together again

Just a quick post today - most of these posts are a "photographic map" so that I can remember how to reassemble the mangle. Given disassembly is now complete, I will be spending a good while stripping and re-finishing the major components. Each will go through a similar process to the smaller parts - paint strip, scrape, wire brush, spray
I did the stretcher today and some of the last of the smaller parts
Stretcher stripped of paint by British Red, on Flickr
First coat on stretcher by British Red, on Flickr
Each piece needs to be sprayed. left to dry, turned, repeated on the back. Then start again on the next coat. I won't bore people with that happening on every piece. I will show anything interesting like the re-finish on the rollers when I get to that and eventual re-assembly

Section 7 - Restoring the rollers
All the major parts have now been cleaned and repainted, so its time to address the rollers
There are a couple (literally) of woodworm holes

So two coats of woodworm treatment before it goes any further

Then I filled the holes and ribbed down - notice how the paint came off?
Filler by British Red, on Flickr
After filling I applied a liberal coat of wood hardener to stabilise a couple of soft patches. Notice how shiny the wood is (the hardener is dry)

At this point I got all scientific. I wanted waterproofed grippy rollers. So one of these latex or rubber paints must be ideal

On it goes - quite streaky and thin on the first coat

Second coat will improve it no doubt

Wrong!
I think either it could not adhere to the hard smooth rollers - or reacted with one of the many chemicals on them.
It had to go

Section 8 - Restoring the Fasteners
Having done all the hard work of cleaning and stripping and grinding and spraying and painting and sanding and varnishing....
I really didn't want to put the mangle back together with these
Rusty fastenings by British Red, on Flickr
I probably could get imperial sized replacements, but the metal is sound - just surface rust. So out with an abrasive wheel

They cleaned up quite well

The screws though, I'm not prepared to put back - the heads and threads are too far gone. I have measured them
