As you say, a bit long in the tooth but still a good bit of kit. We've always used their stuff at work. Although it's always made me laugh that when you are expected to record the way you got the results you write "Fluke!"

Welcome!

I think I've got my head round it, so are they saying that if given three presumed flat pieces, A, B & C, that if A&B, A&C and B&C all contact each other fully (by evidence of engineering blue or whatever) then they must be flat as any convexity (of A for example) being counteracted by an equal concavity of a mating part (B for example) would result in them not fitting flush with a third component (C)?

I'm not very academic so that took me a while.

This thread is a proper education. I think I need to invest in some Rizla! I had no idea it was so useful, especially in setting up the mill.

"Anyone who isn't like me is an idiot".

Aside from the few genuinely light hearted attempts at humour there are some real elitist idiots commenting on here. Pigeon holing people because of their headgear, how childish. I tended to wear one because I don't like getting sun burned and they don't get in the way when rushing to get your head under cars in the pit-lane.

This forum is becoming a real hotbed of misery and small minds. Pathetic.

I think I'd disagree with the counsellors statement. After my amputation I was more affected than I thought I would be, I requested a chat with a counsellor via my GP, who told me I should man up.

I tried manning up for a bit, then got into a very dark place, from which a counsellor (which I paid for from my own pocket) managed to help me from.

As a side note (unrelated to the above), I wonder how many of the blase comments above were made by people in careers which have brought nothing to society? I spent a few years in motorsport, helping rich people drive round in circles. I should be consigned to the junk pile with all the other narcissitic trades I guess.

It may have an electronically actuated brake.

I'm fairly ignorant in these matters, but I don't let that hold me back.

The shape of the firebox looks quite LNER if that helps to narrow it down (or insert a red herring).

I'm an SP8! North Dorset near Shaftesbury. However my Model Engineering Society is BA13 4LY, at Westbury.

nice to see another Model Engineer in the area.

At the end of the day this is supposed to be fun....

On the MoD apprenticeship at Boscombe Down we had to make something similar, but a cube rather than an octagon. Mine was easily, easily, the worst made one in the room.

I would heartily recommend "Car Brakes" published by Crowood Press. In fact I firmly believe everyone should own a copy, even if you don't own a car.

Jon.

To be honest for most small pieces the power feed isn't needed.

So it sounds like you need to change the gears under the cover on the left hand side. Did you get any with it? If not you may need to invest in some to allow you to select the speed you need.

I've only recently started screw cutting on the lathe so I've been messing about with the change gears quite a lot lately!

Personally, (and I am very much a novice and not doing best practise), I use thin brass shims to bring whatever tool I'm using up to the correct height (I also use an ML7). For some of the more commonly used tools I keep meaning to machine a correct size shim but I never get around to it!

I use a combination of HSS tools (so literally lumps of steel that I grind to shape on a bench grinder) and carbide tipped tools. What sort of things do you plan to make? Where are you in the world?

As with everything, positively every person who replies will have different opinions! Techniques vary, some people swear by HSS and don't touch carbide, some people can't understand why people still persist with HSS. I use both because I feel they have different strengths.

It's a lot easier to learn this stuff with someone there to help, if you haven't already, when lockdown is over, I highly recommend joining a model engineering society or similar, I have learned so much from those eager to share their skills.

This thread is a real education. Lots of pictures and suggestions for why certain results are achieved. For someone like me this is excellent reading, thanks all.

Fantastic work.

This thread has been a real education. Maybe this sort of thing should be a Model Engineering Magazine article if it hasn't been already.

I'm completely unattached to ARC, but I did recently buy a Sieg SX2.7L after a lot of spreadsheets and research. It's perfect for my needs, and as I bought the starter set with it (which has a fantastic set of clamps for example) I've been able to throw myself into quite a few projects.

I chose to spend my money up front on the bit that would be hard to upgrade later, the large (for its price range) table. If I want to add DRO or power feed later (As I am sure I will) then I can save up for that and install relatively easily.

I had a small issue with the quill DRO so I messaged them and without quibble they put a fresh one in the post.

I've had that happen to me on a helicopter I was babysitting in the US. The aircrew couldn't work out why they had no pitot-statics.

Horrible job pulling all the larvae out with a bit of locking wire.... *barf*
