Thread: kool mist
26/10/2009 19:12:57
Hi
I just googled this, it makes interesting reading.
one setup costs about £115.
 
I think I'll stick to my cutting oil for now tho.
 
cheers

Thread: Depth of cut
23/10/2009 11:32:20
I've got a Chester Conquest mill and it has a 3 armed handle which is pulled out for drilling and pushed in for fine feeds via a calibrated knob on the front.
 
this feeds down with quite good accuracy.
 
there's a bit of backlash on the feed knob but all the weight is downwards so it hardly matters.
 
for angled working I use a tilting vice and one of those electronic doohikeys for measuring angles.
the vice has an angle scale on the body but there is no datum to line up to  so I removed the scale.

Hi
 I've got a Chester Comet and the slowest that will go is 100 rpm and that is so hairy screwcutting to a shoulder I made a mandrel handle so I can cut by hand.
 
Perhaps when the warranty runs out I'll try doing something about the gearing.

Hi
couldn't agree more on the column tilt, get it truly perpendicular to the bed, do it up as tight as you can, throw the spanner away and buy a tilting vise .
 
something I learnt the hard way.
 
cheers

Thread: 4 Way Tool Holder ??
13/10/2009 21:52:21
I,m only a beginner too, but my personal choice is a quick change toolpost.
I've never liked the idea of having one tool poking into the work and three poking into me .
 
my two pence.
 
cheers

It must be nice to be able to afford the dam' stuff anyway, every time I turn any brass I look at the swarf and cry.
 
I could start a foundry I suppose........................

Hi
I know I haven't had my little Comet lathe for long but I've already got 12 and I got some bar last week to make some more.
 
you will find the main problem is finding somewhere to put them .
 
cheers

Thread: Hot air and stirling engines
22/09/2009 15:14:46
Thanks for the info Ian, I'll have to have a wander round a boot sale or two.
I made the displacer piston from thin balsa sheet eventually, seems happier with that.
 
cheers

Hi
A quick question, would a Stirling engine like mine (see pic from my last post ) work if I made the top and bottom plates from 5mm perspex?
 
I,ve got some smoked perspex doors from an old cabinet that are that thick.
 
then I could put a sealing groove in them.
 
cheers

Have you noticed how many people are reading this thread? I wish some one else would leap in and tell us what they are up to. I hope we are staying on subject or we might hear more of circlip's shopping expeditions, at least we are talking about our engines,LOL.
 
Hi
I wondered if anyone would like to see my first attemt at a Stirling engine ( my first attemt at anything really ),
 
 

 



It's Jan Ridders coffee cup engine featured in Model Engineer.
there are a few differences, mainly the plates are only 1.5mm instead of 5mm, I couldn't get any.
so the temperature equalises quite fast unless I put something frozen on the top, then it runs at approx 60 rpm for about 20 mins.
 
because the plates are so thin I can't put a groove for the displacer walls to seal into so I had to put insulating tape round the edge to seal the displacer cyclinder, removed for pic.
 
the displacer piston is 4mm balsa.
 
It didn't run first time so I made a better fitting displacer rod and changed the piston to balsa (the first one was a cut down CD.
 
I was quite amazed when it ran.
 
cheers

Hi

Thread: Coolant

Hi
I did read somewhere that if you get a fish tank air pump and put an airstone in the coolant tank it keeps it fresh.
just a thought.

Thread: Separating oil from steam and condensate
28/07/2009 21:00:36
I seem to remember in an issue of model engineer a chap fitted an oil trap in the smokebox of his loco,
 
it worked by passing the exhaust into a circular drum via pipes entering the sides at an angle, this swirled the exhaust round and round throwing the oil to the sides ,the oil then ran down the sides and out the bottom whilst the steam exited up the chimney.
 
I can try and find the article if you like.
 
cheers
Roy

Hi
Great minds think alike it seems.

 I couldn't believe it when I saw yours.

cheers Roy

Can anyone tell me where I can get a 6" saucer wheel so I can grind it properly.

Thread: Slot Milling
18/06/2009 16:48:36
Hmmmm ,power feed......drool drool.
 
sorry, got carried away for a minute there.
my mill is a Chester Conquest so I dont expect wonderous things but, yes, it is new and I am still learning ( or at least, trying to ).
 
I wasn't trying to disagree with Circlip, he must know more than me, Hell, everybody knows more than me.
 
I recently tore all the teeth off a dovetail cutter, shows how new I am.
 
cheers
Roy

I am a newbie and haven't been milling for long but I find that provided I take a very light cut and put a bit of tension on the slide lock I can get a much better finish "climb" milling than the usual way.
 
just my two pence worth
 
cheers

Hi
I just discovered I can have a photo album so I've put on some pics of my grinding rest .
 
I'm quite pleased with it for my first serious project.
 
cheers

HI Steve
the rest I'm making appeared in Model Engineers Workshop issue 109.
 
there is a slightly more complicated one, again by Harold, in MEW issue 89 but I'm not into complicated yet
 
can I post piccies on this forum?
I've got a photobucket account I use on other forums so I could show how I'm doing.
 
cheers

Hi guys
thanks for the replies.
 
I was beginning to think it was me, being a newbie to this game, but;
 
I just fitted a dial gauge to the milling machine bed and checked various things, total runout on the spindle is half a thou, its a chester conquest mill so I wasn't expecting miracles.
fitting the collet chuck and clocking the outside gave me half a thou so the chuck is OK.
 
fitting my home made saw arbor and checking that gave me 1 thou total runout.
 
fitting the saw , placing a feeler gauge tween tips and gauge and running veeeery slowly gave me a staggering 22 thou runout.
 
so its not me.
 
Jim,
thanks for the tip, I am making Harold Halls grinding rest at the moment so when that's finished I'll have a go.
 
I can't make them any worse can I
 
cheers
Roy
