Op's piccy is standard issue nothing wrong with it same as my Harrison.
Cross slide i have one nipple open, so put finger over as i pump the carriage plunger.

Just use an oil can press in then squirt, job done.
Other areas do have a ball and need same oil can pressure or wont feed in.

I have my own two volume bible to refer to as I am wholly self taught and most of my machining knowledge came from this book.
It's called Machine shop practice by Karl Hans Moltrecht.
It's an American book with lots of b+w photos of machines and set ups.
Date in the front shows 1979 but the photos look 1960s to me.
I always consult it before embarking on a new project.
Another fantastic book is Machine shop trade serets by James A Harvey another american tome. First printed in 2004 its much more up to date and full of hints and tips gathered by the writer over 30 years of journeyman machining. A lot of his work looks at speeding up monotonous work to make earning his money easier, but its all relevant and downright clever.
Never far away from me to look at and realise how much I have yet to learn.

Bridgeports are almost exclusively either R8 or 30/40 taper, so don't require any great effort to be knocked out. Simply loosening the drawbar does most of the work.

As John Mc suggests, consistently getting a Morse taper stuck means you are over tightening. If the taper and socket are clean, knick-free and lubricated, you shouldn't need much more than a smart tap with a brass hammer to release it.

Having a tee-shirt which declares me to be a Founding Member of the Grumpy Old Mens Club, I am one with the feeling of SOD; my family are quite used to my Bah Humbug approach to Christmas.

But I do not hate Christmas as such. I hate Christmas for what it has become. The whole message and magic of Christmas has been lost. Children getting bigger and bigger more and more expensive presents which the parents can't afford and the children expect but don't appreciate. Compare that with our youth when parents were hard up and we were more than happy to get anything at all.

Christmas adverts from end of August onwards, shops stuffed with Christmas goods for months before, compulsory Christmas music blasting from every shop for weeks, and then the shopping. Horrible. Hide in the shed time. Tons and tons of food bought, because we 'must have some of this' or 'some of that', how much goes to waste, must stock up as the shops will be shut for one whole day.. How much do we over-eat and drink? We buy as well bottles of booze that never gets drunk for ages, plus that bottle of 'whatever' that no-one drinks but we'd better get a bottle in 'just-in-case' cos Aunty Whoever drinks it and if she turns up'....

There is not this hype in France, or at least the part of Brittany we go to. Things are so much more calm, the lack of hype and great expectation means Christmas is so much more enjoyable, though still expensive!

Whatever happened to the message of Christmas, to peace and goodwill to all men? It has all ended up as one huge raid on my wallet, depriving me of essential workshop goodies and depriving me of essential shed time, that's what's happened to Christmas.

Bah Humbug to you all.

Chris

PS. When we moved to our present house 10 years ago some idiot had planted a Christmas tree in the garden years before which by then was 45 foot tall, give or take a yard or two. Dominated the garden, took masses of space and light, hid a beautiful copper beech tree behind it. Cost £400 to have it cut down, but well worth it. Beware, those thinking of planting this year's tree. Ours is a suitably plastic and fibre-optic jobbie, will give years of service, none of this £25 plus a tree rubbish you end up putting on the tip 2 weeks after Christmas Day - why clutter your house with it, shedding needles, why not go straight down the tip and just throw £25 in the skip and save the mess and wastage. Bah Humbug. My wife really loves me, this time of year...........

Morning folks.... while we’re on the subject of Boxford lathes - has anybody dimensional drawings of a splashback for the lathe? I could makeup a simple one but I sure it would be usefull with a shelf option for the Dixon QCT holders. The retired edges will make it sturdier as well.

Yes, same problem on an AUD - don't oil it so much. It really doesn't need much.

I do know Bob very well, drag bike racing is too small of a world not to know Bob or Pete Davies. I would love to see pics of your bike if you can find them. It was Bob that showed me how to Bronze weld before i built that frame.

He's just retired from racing (and work!) and his bike is up for sale...here it is. It's entirely built in his workshop on manual machines - cylinder head, frame, bodywork, the lot. It's 1700cc, supercharged and running on methanol.

Hi Dave,

I’m not sure how well the shoulder bolts will do the job but worth a go. The original plan was to use rollers from roller bearings, readily available and quite cheap but only available solid and I want to keep the mass down on the moving bits!

Pistons have all been milled and drilled and the bolts cut down and hollowed out to make the pins. Rapidly running out of 5 off parts to make

Few pictures of my motorcycle. Built from scratch in my sisterscellar. It's been quite competitive so far, winning the 2016 championship and 2nd this year too.

Lots more info and build stuff at **LINK**

Slightly OT but 'World at war' is very good if you are interested in WW2

Some time has passed since I fitted my ELS to my EMCO V10P lathe, and so far I am very happy with how it all works, so much so that I have just finished fitting the same system to my new EMCO 14D Lathe ( well, nearly one year old now..)

Makes threading a real breeze! And gives a very nice autofeed with no gears...

Posted by Sam Longley 1 on 14/12/2017 08:07:01:

I have a Warco WM 16 ( the one with the 2 morse taper bought new) & I doubt whether I could actually machine a single groove like that in less than a couple of hours. Let alone the rest of the operations for the fitting.The vibration etc would be horrendous even with brand new cutters from ARC.( not cheapy ones)

Do others find a WM 16 capable of such a task?

A cold afternoon in the workshop - +1° C inside when I went out. Decided to put a little heat on with a single radiant bar heater which raised the temp to +5° by time I had had enough! Managed to get a left handed thread put on a shaft for a potters wheel build for a neighbour. All turned out nicely - if you pardon the pun! Seasonal greeting and wrap up warm if your escaping to the workshop! John

made a tool holder for my dickson toolpost, lots of angles to mill got the grey matter going.

Finished off my mother’s xmas present today - a display cabinet of tools left by my father, an ex- Vickers apprentice who later worked with Barnes Wallis during the later years of the war, and afterwards became a teacher (of engineering workshop theory and practice as it was officially known by those in the know, metalwork to everyone else).

Many of the tools he made himself, but he was a big fan of Moore and Wright, Browne and Sharp and Starrett. The mic was a B and S and always carried in the pocket of his white workshop coat.

The case is made of teak reclaimed from a refurbishment of Exeter library many years ago, and the photo was taken before I fitted the glass and beads to avoid reflections.

Thanks George and Eric. That's enough information for me to give chalk a try. On the downside I shall have to develop a steady hand!

My current, rather slow, method takes three stages and is in line with Thor and Andy's advice:

• Step 1: Centre the work roughly using the jaw markings
• Step 2: Centre more accurately by turning the work relative to the tip of a knife tool. I do this first by eye - closing the gap and then check with the cross-slide graduations
• Step 3: Adjust with a DTI mounted on a magnetic stand on the cross-slide as per Thor. With patience I can reduce run-out to zero (within the limitations of my 'inexpensive' 0.01mm DTI)

Get thee behind me NJH, Chris and Thaiguzzi! I am tempted. The longer I spend in my workshop the more I want a QCTP. I hadn't thought of a Quick Change DTI but now you mention it the advantage is obvious. And xmas is coming.

Apart from the time taken to centre my 4-jaw chuck, its main shortcoming is that it won't grip anything less than about 3mm diameter. Which leads me to my other desire - a collet chuck.

I'll report back later how well I get on with chalk.

Many thanks,

Dave
