Thread: which lathe?
28/11/2019 11:43:48

+1 for SC3 from ArcEuro - unless the bench space is an issue as the next job may be longer so SC3 was my choice in place of the SC2.

You need to include the tools that you need to complete your jobs as well, so the collets Robert suggested and a drill chuck as well as cutting tools ought to be on your list - but buy as you need and don't try to get everything possible at once - I suspect many of us have bought things to fully equip a lathe that have never been used in practice!

Thread: Inside chuck jaws

Posted by Robin Graham on 26/11/2019 01:42:08:

it's only a matter of reversing them and remembering that jaw 1 becomes jaw 3 when putting it them in backwards to grip larger diameters.


I have just picked up a small lever 3 jaw SC chuck to go in a rotary table. It came with no instructions, but no problem - why would you need instructions - until I read the above.

Is this jaw reversal usual and necessary?

Thanks for your replies

If I put up a post that is considered unsuitable for any reason and removed by the moderators will I know about it?

A couple of posts I have made from work have not appeared on the forum and I wonder if it because they have been moderated (I hope not - I try to avoid anything too off the wall) or blocked by filtering at this end?

Thread: Knurling tool operation
23/11/2019 13:37:18

Thanks guys


22/11/2019 17:37:03

Have just ordered a knurling tool of the clamp type - I wish to use it to finish some parts of the Hemingway/Thomas height gauge.

I have never used a knurling tool before so some suggestions for lathe speeds and whether to do it under power (at present I assume this is correct)

The parts are about 1 1/8" mild steel and 5/8" brass.

Thanks for any help.

Thread: Tungsten or Alloy Steel Taps and Dies
17/11/2019 14:43:07

Browsing eBay and I came across a cheap set of taps and dies that are described as being made of 'alloy steel'. Later found the same set under a different brand described as being made from 'tungsten steel'

Not interested in buying either set but just curious to know what 'alloy steel' and 'tungsten steel' are and are they similar to carbon steel, high speed steel or muckmetal?

Thread: Angle Grinder stand

For a 4 1/2” Grinder. Any recommendations?

They seem to vary in price from £10 to over £50!

I bought the Einhell one from Machine Mart but it looks as if they only sell the larger one at present - however it is a clone of the Wolfcraft and I am happy with it.

What I have done is screwed it to a piece of 2"x2"x12" approx wood so that I can clamp it in the Workmate when I use it rather than having it fixed and so in the way or alternately just floating about the place.

Thread: Grinding and cutoff discs for angle grinders
14/11/2019 21:47:47

Used to work with a retired toolroom grinder, in a place where we sold the disks and he hated the things and always told any customer who bought any about them shattering and embedding themselves in a concrete pillar in his toolroom.

Put a bit of a dampener on counter sales, but he was sincere!

Thread: Allchin 1.1.2" boiler
06/11/2019 17:47:29

It is an interesting position to be in - we know nowadays that there are better ways of doing things, but if we do things differently to the design drawings when does it become a different design and calculations etc need to be produced?

Just curious!

As far as I can see the throatplate needs flanging on the sides backwards into the firebox and forwards into the barrel. This makes for an interesting shape to the copper where the backwards flange meets up with the forwards flange. Must be possible, I imagine all loco type boilers have this double bend at this point, but can't find a photo of one in my limited collection of books.

Not necessarily. This is the drawing of LBSC's Tich loco throatplate, although admittedly some boiler designs do have the 'forwards and backwards' flanges you describe.

Not far from me. Very helpful and nice people.

Thread: new computer

I have been a very satisfied customer of these people for a long time - they have taken over the Morgan Computers business. Most recently an A1 reconditioned iPad **LINK**

Remember a new system will probably have Win10 installed perhaps unlike your present one - many people don't like this and some of your present software may need updating, but with win7 going out of support it is hard to recommend a different version if you are going down the Microsoft route.

I remember reading about someone cutting through iron bars using thread wetted and dipped in sandy dust off the floor. Took ages so the cut was disguised with more dirt.

That was how jade carvers cut the extremely hard jade.

Thread: Lathe chuck guards - how many folk use them?
01/11/2019 10:59:05
Posted by David Davies 8 on 31/10/2019 15:44:31:

Hijacking the thread slightly, what does one do about guarding a shaper, which is possibly more dangerous than the above mentioned horizontal milling machine?

I don't have a shaper, but used to use one regularly at a previous club. A magnificent beast, it would take on jobs that the millers wouldn't touch - but it was too easy to listen to the rhythmic cutting and be distracted by conversations and other things happening in the workshop during a longer cut.

A hacksaw machine (mounted UNDER a bench!) was another tool that could be set working and then left to get on with it on its own with less attention than it perhaps deserved.

So to add to the take care and use common sense advice I would add pay attention!

It is safe to say we cannot now build steel boilers without being coded welders and using certified materials, with all the entailed rigmarole and costs. We don't want dissatisfied boiler inspectors!

Like Duncan above, never let it be said that I am at all pedantic, but however without differing at a practical level, the boiler code does not quite say this.

Para 6.2 says that "If welding is undertaken by anyone who is not a coded welder the inspector shall require that weld samples be made available for inspection and testing prior to the commencement of the welding of the boiler, or that the welder should have proof of test pieces being satisfactorily tested within the twelve months prior to the jointing being undertaken. Weld samples shall be tested by appropriate testing laboratories."

In practical terms it would probably be beyond the reach of most of us to meet the conditions required, but also note that steel is not mentioned and with TIG machines available on the High Street, complying with the code would imply that this applies to TIG welded copper too.

Thread: Jacobs model 6414 chuck - removal

If yours is the same model chuck as on this Wolf Cub drill this link shows you how to remove the chuck at about 6 mins in.

Thread: Coke for brazing purposes

Is coke generally available? Last time I looked to buy some it was unobtainium in small quantities. (I did find a local coal merchant selling it by the ton.)

This is where I have seen it - close to me, but perhaps not to you.
