Swarf production is in full swing.
« on: May 29, 2010, 05:42:08 PM »
Yer 'tis then.

This years quota of swarf has started with a vengance  :ddb: started machining up the parts for the little pump I got from southworth engines.

 
 Family group shot.                                                                                     Finished Columns.

    
 Going old school with a 'sticky pin' setting up on the rotary table,                  Now just about to start milling up the pump base.
 not happy with all those new fangled doo-hickeys.

I wont bore you all, all in one go, so here's a link to my flickr page http://www.flickr.com/photos/techno-ludite/sets/72157624037389809/ with the rest of them.

The next post I shall try and include a few more of the ones that I forgot to get pics of.

Looks like your having fun  :headbang:



Sticky pin eh?  I'm obviously not old.... erm, school enough to know this one  :scratch:



I don't know about this castings stuff.... I would have thought you could make those bits from bar stock? Then again you'd need the plans I suppose?



Still looks good :thumbup:

I'd liked to appologise for using profanities on this site.

Swarf production was stopped last week due to a really horrible case of 'man flu', these head colds can knock you sideways when you least expect it and there is no mrs ludite to mop my fevered brow when I do come down with the lurgy, and wouldn't know it those buggers at ( profanity alert ) work :whip: needed me to do something or another   :coffee: .

But here is the latest offerings to the god of swarf production  :bow: ,

    
  Undercutting the pump valve.                                                                 Group shot #2

    
  Pump valve drg.                                                                                      One of the pump unions.

  
   Cylinder bottom finished milling.


And the rest are on my flickr page, http://www.flickr.com/photos/techno-ludite/sets/72157624037389809/  as usual

Hmm it looks as though I've made a bit of a balls up on the pump valve machining, oh well back in the lathe it goe's again tomorrow night.

Techno.

Must be a great feeling being back on deck!. Its looking good.

Divided… sticky pin= chewing gum or plummers putty stuck on the end of your  collet holder or chuck with a needle or any sharp pointed pin placed in it , turn the spindle on and slightly hold the revolving pin between two fingers and get pin to revolve true just like a wobbler stick center finder only this set up is only worth about 5 cents works every time.

Keep up the good work brother..           Anthony.

No machining tonight just didn't feel like it, carp day at ( profanity alert ) work  :whip:.


The use of the sticky pin was shown to the apprentices on our first year training course away from our companies. by the milling section instructor. What you do is put a dress makers needle in some 'plasticine' pointy end out, stick it on the end of what evers in the chuck, spin it up, touch on on your work piece till the needle point stops wobbling about and there you have it, centre of the cutter over the edge of the job, move the workpiece to the required dimensions and as we say 'bobs ur uncle' an 'fannys ur aunt'.

If that lot makes any sense, then i've explained it better than I thunk I did.

Hi All

Bin busy this morning. I'm a great believer of a picture telling more than I can put down into words, so sorry if the write-ups are lacking.

   
  Form tool ground up correctly.                                                                Milling the wings.

   
  Finished milling                                                                                     Valve in-stu in the union to see if it fits.


  1st off.

 
  Its there somewhere                                                    Ah there it is.


And the rest are on my flickr page.

Hi All

Been a slow month so far what with losing my mojo  :scratch:, then getting back at the weekend  :med: . So here are the latest updates on the pump so far.

 
 Machining the back face of the valve plate.                                               Finished machining.

 
 Shuttle valves part finished.                                                                   Trial fit of the shuttle valves.


 Gasket clamped between valve plate and body.

Gonna try and get some more done this weekend so keep looking.

Hi All
S'bin quiet on the swarf production front of late, finally managed to finish the pump last nite, my neighbours will be glad when I shut my workshop up for the winter no more security light flashing on and off. Anywho here's somemore pics of it, tested the water side this morning an she pumps ok, just need to rig it to my boiler or an airline to see if the steam side works as well.

 



TL  :)

And this is the engine and boiler set that its going to go with.



And using utube for posting vids is a lot easier than using flickr   :ddb:

That look nice. a few questions where did the casting kit come from and how big is it I have tried to work it out but I think I am wrong at 3 1/2 in tall

Morning/Evening All   :wave:

Yes the pump is just over 3" tall and I got from a company called 'southworth engines' http://www.southworthengines.smartemail.co.uk/ the company advertises in the back of 'EIM' and elsewhere I expect, the cost of the kit was just under £30.

Nice work on the Pump J.L...couple of questions ...are the Southworth pump part tolerances very tight to the drawings...and where did you pick up those Clico Clamps?
All the best for now,
                           John.

On the one I've done, more like a male appendage in a bucket, but I've tried to get as close as possible to the drawing dimensions with the kit I've got. And regarding the edge clamps not legally, I used to work on 'Harriers' at BAE nuff said. But give these people a try http://www.skinpins.com/fastsideclamp1.html or any company that deals with aircraft manufacture, I see that your in the emerald isle see if you know anyone that works at shorts brothers in belfast.

Behold my latest baby, not bad considering I'm single.



Yup she works at last, it was a bit nerve racking to say the least when she took her first breath's at 16:02 today, got to sort out the plumbing and wot-not.

Hi Peter

Thats a very good question, I think when I posted the vid it was a fluke 'cos now I can't get the darn thing going again. I think i'll need a separate steam take off for it and then set up a by-pass for the water system.
Hopefully now site work is starting to drop off I can get back at it again before I shut my workshop up for the winter.
