Your lever operated holder on the QCTP looks good – I can imagine using it for cutting keyways in bores – any change of a write-up ?

Trust you Neil. And now I have a picture of Paul with a boat on each foot a pipe strategically placed skipping over the water at a rate of knots.

A keen photograther friend Roger Walton wanted to take some pictures before I stripped it so here is one.

Just one question:- Did the bushes and shed survive?

[BazyleParticipant @bazyle]

Not much left of the Fergie's outer bearring. But why would anyone design a hub with no scallops to drift out the outer bearing shell and barely 15 thou of the shell exposed.

Went to the Bolnhurst country and vintage fair. Met a chap I had worked with years ago who now owns a nice Fowler engine with old style travelling van. Although well into retirement he still works full time in his garage turning parts for all and sundry in order to fund his engine. I expressed surprise that there was such demand left – enough to keep him in full employment that is but he has no problem, and its all done without advertising, just word of mouth. In his spare time he is building not just one but two 5" Brittania's,, well done Ian.

Also took the opportunity of introducing myself to Martin Perman of this very forum who was exhibiting one of his Lister engines – nice talking to you Martin and I hope it has stopped raining there by now.

I thought one of my fathers day cards felt a bit thick through the envelope, my son had slipped a new Zeus book in with the card. Just in time as my old one is falling apart. Thanks Chris, just the ticket!

Neil I keep of the baked beans it has same effect as the nickname.

V8Eng it is an illusion with the camera the shed and bushes are a long way off the flames seeing the positions the professional photographers get into for shots not all is what it seems.

Just went to York to buy another batch of American piano wire from the local model shop to make another lot of paired valve springs.

Old Renno red eyes got through the MOT this morning I tried getting Classic car insurance for it but most insurance companies are not happy if it's your only transport.

Back to the workshop for a few hours then have been invited out to taste the local churches brews.

Rik,

It was a pleasure to put a face to a name, one of the conditions of restoring and showing Stationary Engines is the fact that you have to spend the weekend constantly damp, you get used to it this evening I took my friend back to Bromham and we saw two Dragon Rapides flying in formation your way, one blue and one silver.

Bees again, now that the swifts and swallows are here I am starting to lose bees, in fact I have now 2 Queen less hives as the Queens have gone out on mating flights and the birds have taken them. The swallows fly over the apiary and take bees, Drones fly up and make a drone congregation and a virgin Queen seeks this out and so do the swallows.

I am now in the process of trying to find a Queen (mated) and been lucky enough to find one near Folkestone and the cost £35. collected.

This happens nearly every year and puts me in a difficult position trying to re-queen hives. I usually unite 2 hives together and that way it gets a queen, thats whats happened, again as the new Queen has been lost. Frustration.

Thanks Bob,

I'll try to put something together in words and maybe drawings. I've created an album and added some more photos to it. It's basically finished now except for a handle, removing machine marks and I might even paint it!

is the QCTP fitted to a WM180 ? – if so any problems (it looks rather like the ArcEuro supplied Piston) – even as an absolute beginner on the lathe the 4way post is already my least favourite item

Edited By Frances IoM on 20/06/2015 22:53:35

[Ed DuffnerParticipant @edduffner79357]

Hi Frances,

Yes it's the WM180 and the toolpost from Arc'. It has a replacement sleeve and a bored bottom section to fit on the WM180 compound slide.

Regards,
Ed.

Got up early in case I was needed as second tug pilot (weather is duff so no), and then proceeded to produce a load of scrap in the workshop.

This is what happens to poor quality tooling that contributed to the scrap:

It's the mechanical equivalent of 'Widlarising' and the bits will be going in the recycle bin. The ex-taps and die were definitely poor quality, bought many years ago before I knew better. I think I know where they came from, and I don't use that company any more.

Andrew

Addendum: Widlarising – named after the legendary IC designer (µA709, LM109 and the Widlar current source just for starters) who advocated smashing any component that had caused problems with a hammer. It stops some other poor sop using the same component, and it makes you feel a whole load better!

Ed Duffner`s toolpost slotting tool is a super idea. Now I know what to do with that 1MT socket toolholder that just just hangs around gathering dust.

Shock horror! Opposing cricket team fielded two ladies who turned out to both be excellent bowlers. But we won so reward for most of yesterday working on mower and tractor repairs.

This is probably the wrong place to post this; but I don't think it merits a new thread:

Manchester Evening News, last Thursday, featured Nasmyth's Steam Hammer.

I spent all day trying to set up my imperial lathe to cut a metric thread.I thought I had got there but the sums don't add up.

So I have a 4 TPI leadscrew and want to cut a 1.2mm pitch thread. I don't have a 254 tooth gear and I can't use Geo Thomas's Myford gearbox metric conversion ratios either.

I work out that 1.2mm pitch is equivalent to 25.4/1.2 = 21.166 TPI. So if I start of at the headstock and have a 20 teeth cog, then a shaft where the 20 meshes with a 60 and on that shaft there is a 30 that meshes with a 60 on another shaft. So I have got a 6:1 reduction, so if this shaft was linked directly to the leadscrew, I would be cutting a 24 TPI thread.

But I want a 21.166, so I have to step up the 24 TPI to this magic number. I reckon stepping up by the ratio of 9:8 will be extremely accurate (1.2008 actual pitch).

The real problem is that just before tea, I used a step up ratio of 63:36, 7:4 and I got a MEASURED pitch of 1.2mm.

When I came in, I thought I would write up what I did, so it would not take all day the next time. That's when I calculated that my choice of 36/63 should give me 1.54mm pitch and that 9:8 should be the correct ratio.

Should I ditch my vernier? have I got some slippage and the numbers just seemed OK. Anyone got any references/suggestions or words of wisdom in general. I shall be checking the number of teeth on the cogs compared to their labelling!

Fitted the anti vibration feet to my mill. (big improvement)

While I was grubbing about on my hands and knees I also connected the wiring (that I should have done ages ago) to the emergency stop kick bars.

Yesterday evening the woebegone young lad from over the road brought in his Golf cylinder head.

(ally head + exhaust stud) * (young lad + big spanner) =

Drilled out the sheared stud, drilled, tapped oversize M10 to take a liner. Tapped that to M8 so he can use standard studs.

I feel your frustration Clive. Nevertheless, I found your post most interesting and educational – thanks for posting it. I hope you find yet another queen at reasonable cost soon. Coincidentally, I have just watched the bee-eater bird episode of "To the Manner Born"

You've lost me. What is your whole gear train that you actually used to cut the thread?

Frank,

I would check the actual pitch of the leadscrew first.

[JasonBModerator @jasonb]

Frank did you measure just one turn of the thread? better to measure over 10 or 20 turns as the error in using the venier will be less

[Clive HartlandParticipant @clivehartland94829]

Bees again, I have now found a Queen Bee breeder near Folkstone, trouble is, 'Operation stack' is happening due to a strike in the French port. This is the route I need to take to get there for the Queen bee. I will have to leave here (Gillingham) at about 0700 tomorrow. I understand that all traffic is being routed via the A20.while lorries are stacked on the M20.

The Queen Bee will cost £35 and is already mated. She will come in a cage with a few attendant bees and the cage has a candy plug which the hive bees will eat away and at the same time get the Queen pheromone so that she is accepted/. You cannot bung the Queen Bee straight in the hive as they will kill her.

[frank brownParticipant @frankbrown22225]

I;ve cracked 1.2mm (I think). . .24 on spindle meshing with 60 on shaft with a 38 which drives a 36 into the 2:1 leadscrew gear box. Ten turns on the chuck is 12mm -+ .00 on a reasonabley priced (cheap) digital vernier.

I have looked at calculating other ratios, I think 1mm is 20,60,38,36. Like 1.2 but lead screw is rotating 20% slower, hence change from 24 to 20 as the spindle gear. In the same vein, 1.5mm should be 30+60+38+36.

.8mm and ,7 are inscrutable at the moment, 1.25 needs a 25 tooth gear which I have not got.
