Thread: Have You considered getting a 3D printer

Downside to this industry are muppets who print weaponry which could bring in regulation like what happened with drone technology

There are a lot of muppets out there

You mean like the regulation of Lathes and Milling machines which has been proposed repeatedly over the years by clueless politicians with no manufacturing or machining experience who don't realise that it's impractical and stupid to try to control illegal misuse with bans and regulation?

Do what you do in other rooms where smells are frequent, use an extractor.

There was a time when all you had was HSS. People seemed to manage quite well too.


There was a time when all you had was hand chipped flint, people seemed to manage quite well too!

HSS was adopted by Model Engineers when it was literally Cutting Edge in industry, the desire to stop time and manage with what Great Grandad had when he was actually using the best available technology at the time is quite funny!

Thread: Coventry Quick Change Tool System

Cutwel have remanufactured the Quick Change tool system with the R8 adapter at under £100 and the holders priced better than previous stocks, Leigh Cole at Cutwel assures me the holders are back compatible with the old system

Thread: Hey you! What lathe? Why?
08/02/2021 23:53:25

I used to espouse an Emco Maximat Super11 (later big bore model), latterly I transferred my affections to the rather lovely Harrison M300, typically when a new lathe finally came my way it was neither of these.
When choosing a lathe keep in mind that 4 things in life are sure, death, taxes, that you will want a longer lathe and that you will at some point wish for more capacity through the spindle.

Is there more than one Emvio as they don't seem to have any CNC machines listed?

Syil maintain their own site for their UK product offerings but Emvio Engineering are the current UK agent for Syil, it used to be some box shipping outfit but now things are much different.

I've had my Syil X7 running without problems for a couple of years now, one of the things which encouraged me in the decision was the involvement of UK based Emvio Engineering as the UK agent, customer service has been outstanding.

Thread: Where do you put your chuck key?
10/05/2020 21:46:49
Posted by Sam Spoons on 08/05/2020 13:03:15:

The things you need close at hand when working in the lathe? Things like keys for the QC tool post and tool inserts and the toolholder needed for the job but not for the current operation?

The obvious place for the chuck key on the Boxford is on top of the headstock with the spare tool holders on the back of the cabinet behind the bed but is that good practice (I always stop the lathe before reaching for anything but leaning over to get a different toolholder seems wrong somehow)?

Good practice is safe practice, if you always stop the lathe it's safe, I keep all of my tail stock tooling and head stock tooling on the wall behind the lathe, along with most of my QCTP holders.

Thank you Gentlemen I didn’t make myself clear. I have a full set of drills offering the minor point sizes between the 2-3-4 mm etc.

I was asking in relationship to Milling cutters. My preferred supplier is ARC Euro and they only sell milling cutters in the full mm sizes and not in sizes between the 2-3-4 mm etc.

The steam way I want to cut are not holes in the steam chest but are ports ie the size I require is 2.4 mm wide x 9.25 mm long hence my question do I go up a size or down if I only have milling cutters to the whole mm size

If slots required "On Size" cutters we would all end up with an infinite number of cutters, you use the next size cutter down but you cut the slot or pocket to the correct size!

Use a shim disc between the inner races to provide the required pre-load.

Thread: Bending Stainless

Posted by John Olsen on 30/01/2020 22:50:45:

I have tried to silver solder stainless, with the right flux it can be done but I would not recommend it. TIG welding is the way to go with stainless, it is easy to do and provided there is no gap, you often don't even need filler. I found when making tanks for my steam launch that flanges are not needed, in fact they are a liability, and a corner will weld very nicely.

If your piece is shaped like I think it is, I would look for piece of tube the right size and the length you want the flange, and cut a piece of flat to match. Then I would Tig weld around the edge.


316 will form, why muck about?

Machine DRO (Allendale Electronics) sold Sino DROs, if you ask them I'm sure they will be able to help.

Thread: Workshop insulation
11/04/2020 19:19:07

My workshop was, until recently, a 5.2m x 3m Yard Master garage of plastic coated galvanised steel construction.
I devised a means to fix wood into the U shaped internal supporting members of the walls, filled the spaces with insulating sheets cut to fit and boarded out the interior walls with 18mm OSB. The roof was insulated with 25mm Celotex.
The workshop stayed above 10C in all weathers in Yorkshire with just a desktop PC running and I never had any issues with condensation.

Thread: Myford Super 7 with 'Big Bore Conversion'
07/04/2020 14:09:57
Posted by Mike Poole on 06/04/2020 23:03:41:

I doubt it would be practical to build a big bore headstock from parts, it would be a long and expensive shopping list. It would make more sense to part exchange your current machine for a big bore I would think.


That's what Roy Milner did, with most of the parts being taken from the headstock being converted, no new gears or pulleys were used.

Posted by John Haine on 05/04/2020 14:08:49:

why on earth they didn't just make it ER40 in the first place I don't know.

John Stevenson suggested a native ER40 headstock would be the best option for the Super 7, I think Myford were just making a point of ignoring him and common sense by finally employing the MT3 design which one of their employees had come up with in the 1960s or 1970s.
Perhaps the "New Myford" will go with ER40 sometime in the middle of this century!

NIck..Did you strip your headstock and have you any details and bearing numbers? Ive contacted Roy Milner and hes not making any more big bore headstocks.

So i may attempt it myself with a bit of help.

Thanks Pauly

I haven't needed to strip it yet and it's used every day for production work at the moment, I currently have a rush of orders owing to people being at home with nothing to do but fit upgrade parts to their projects.
When I get around to stripping it I will put all the dimensions into CAD and I have an idea or two for improvement when I convert my spare head,

Thread: New chinese lathe or old Myford lathe

If you can find a reasonably priced one then a Myford S7 in good condition might serve you well, if you can live with the lamentable headstock through capacity. 25 years ago I paid £700 for a 1964 Super 7 which is still turning out precision work.
The problem is that for what people seem to think is a reasonable price for a second hand S7 you can now usually buy something just as good and newer from a reputable UK based supplier.

Stainless has nothing to do with this sad story.
The cheerful purchase of Mystery Metal because it is seen as cheap is the story here.
If you buy known materials you can look up heat treatment and cutting speeds, this saves you looking like the chump who has bought Scrapbinium cheaply and now cannot do anything with it.

Thread: Indexable Carbide Turning tools

The ideal depth of cut is about 0.6 times the tip radius.

If you are the sort of person who likes to make shallow finishing cuts I suggest CCGT inserts with a small tip radius.


How does that jibe with a single step 30mm to 25mm reduction in 303 on my S7?
