The guys at the engineering shop shovel all the oily sawdust into a big wooden packing crate, about 8' x 8' x 6', then in winter use it to heat the building. There is a carpentry place next door where they get the sawdust from. They also collect any wood offcuts for the same purpose.

Hi Baron,
Not sure if you have been reading the Weir pump thread but you have just put a wood heater on the 'I must make' list.
It sounds like I am going to have a good fuel supply from this lathe. ( insert smiley as the computer is packed away and I have to use the phone for a bit)

Look what has arrived. Still to come is the Granite slab which measures 1600mm x 1000mm and hopefully a Kondia vertical mill, a Waldown pedestal grinder and a Waldown drill press.

Apologies for the quality of the pics but it was early, little light and I was excited

Before you ask, the rotary table is 12"

Hi all,
it's full steam ahead (pun intended) on this thread again. The boss has given me nearly three weeks in a row to get some badly needed restoration work done.
I'll finally be able to finish the Worthington pump, I'll be making the new piston rings today then giving it a test run. After this, I'll be starting on the rather large Mumford wall/banjo Pump (must see if I have a pic), looking forward to that project.
I'll put up some pics tonight.

I managed to get some done today, not as much as I would have liked but a good start nonetheless.
First job was to go out and get the modern equivalent of Ebonite (hard rubber... think bowling balls).
The modern stuff is called Ertalyte (PETP).
We had this stuff on order for the Weir type feed pumps on the boilers as they originally had Ebonite piston rings (water end) in them. The piece we ordered was a lot bigger in diameter than required for the rings on the Worthington pump so in order to not turn most of it into curly bits of string I decided to turn the larger rings for the boiler pumps then do the smaller ones.
A bit tricky but all went well.
Hopefully I can start the smaller rings tomorrow.

Nice one Phil... 3:1 was what you were thinking of, wasn't it...

How does that stuff machine, does it come off in long strips and tangle around everything like some other plastics?

Hi Ray,
Hmmm, I may have exceeded that ratio just a tad but if I spun it fast enough I could create a gyroscopic effect and...

Ertalyte machines like most other plastics (well, it does for me

) but with some creative tool grinding it could be made to hit the back of the head of the guy machining on the next lathe, if there was one

.

Phil thanks in that post you have answered a number of questions of methods that wasn't sure how to do or if they could be done that way.

You ain't seen nothing till you have machined rubber, way worse than acetyl or nylon. If the stuff Phil is using has a good elongation % it will be just like the PU rubber i have been turning.

Glad to see you posting here again Phil, and with the new Colchester in use!

Hi Ray,
When I was an apprentice my boss told me "you are only limited by your imagination". He may have been right

Hi Ewan,
This stuff is easy to machine, compared to rubber.
I have to say, I am loving the bigger lathe. I had to use the Bantam as well today, it's a fine bit of kit that one.

On to today. I nearly got the rings finished, just a couple of stumbling blocks along the way. I needed a 1/4" UNF nut for another job. No luck with that amongst a gazillion whitworth nuts and bolts

Some more pics.

Hi Phil,

Nice pictures, showing some very interesting machining techniques.

I did wonder what the warning label said though !

**krisfarm** · 28th November 2014, 08:06 AM

Hi Phil,
Great photos and machining with the attached text , innovative tool grinding for the ring cutting tool. In situations like this we all need a long nose live centre and a face plate with a few extra slots in it.

Phil I had a similar couple of Tech teachers, tradies and boss. Then there are the fellows on here who have re-opened my eyes and mind for that I thank them all.

Love that special tool you made.

**DSEL74** · 28th November 2014, 02:11 PM

Phil, is that Colchester the student or Master? I have the master 2500.

ThanksBaron,
Sometimes wondering how in hootin' hollerin' I'm going to do this, with what tooling I have, is half the fun

.
The label with the skull and crossbones (this will make you laugh) is entirely about feeds and speeds and tool angles and how if these parameters aren't strictly adhered to they won't be liable for stress fractures, warpage and any other failures that may occur. Nothing is mentioned about health issues (if there is any).

Thanks Bob,
I wasn't sure if the text in the pics helped or hindered. Gotta agree about the long nose live centre. Didn't need it eventually but it sure would've been handy. Besides, where is the fun in having the right tools.

Hi Dale,
That one is the Triumph 2000, I'm pretty happy with it though the topslide is in bad need of some work.
I'll save that for a time when I am walking aimlessly around the workshop with nothing to do

I nearly managed to get all the rings machined but had a couple of other chores to do first.
One of them being repairs to the very boring bar I needed to bore the rings to size.
The best interruption was picking up the Alfred Herbert drill press (last 3 pics).
While driving around I saw a planer on the back of a truck with other antique engineering equipment. Needless to say when we got back the truck was gone.
Investigations have begun and I should know which way or the other about it on Monday, Fingers crossed.

Hi all,
A bit more today and yesterday (with a few distractions).
I got the rings finished then had to make a jig to hold the rings and cut the gaps.
Hopefully tomorrow I will be able to fit the pistons and rods and if all goes well I may be able to give it a dry test run
