Thread: Electricity Supply
08/06/2019 18:30:50

People made similar arguments 100 years or so ago as internal combustion engines replaced horses and steam. Other people, including engineers saw the opportunities and became very wealthy. The same thing will happen today with electric cars. There are big challenges to making it work but people will come up with solutions.

British engineering companies could and should have been in the lead on this, it's going to be a huge growth area.

The reality of nuclear power is that it's been around for decades, has been taxpayer funded for billions of £ in this country alone and has left a legacy that will last for decades and will cost billions of £ to clean up. No one wants a nuclear power plant near them and people are just scared of them. It's never delivered on its promise and unless there are major changes never will. It's a great idea though.

Thread: Model aircraft pilots angry over drone laws
07/06/2019 09:43:59

It feels like an over reaction to the drone threat on airports. I was listening to a Radio 4 piece about it a couple of weeks ago, a security expert seemed pretty confident that police and airport security now have the right technology but more importantly command and control to deal with any drones on airports.

Not done it yet and your point about guns - I think the difference is that many guns only have 1 purpose which is to kill people and preventing people from using them does save many lives - just compare America with the UK. Yes, that is a restriction on the freedom of people who want to own a gun which is price that we, as a whole, are willing to pay in the UK. In America, as a whole, they are not willing to lose that freedom but have the school shootings and all the rest of it.

The point about cars and driving, having MOTs and licences etc - I have never heard anyone seriously suggest that people should drive cars with no training or licence.

All these things are a balance between individual freedoms, the need to protect other people from deliberate or accidental harm and the costs / hassle involved in regulating things.

Thread: Viceroy lathe
06/06/2019 10:30:25

I have a Viceroy too and there are no mounting points for a milling head.

What I do know is that there are a huge number of minor variations of this lathe. Every one I have seen is different in some way. So it wouldn't surprise me if a milling head was offered.

If your hypothetical friend decided to get rid of the problem by pouring it out into the ground (which was a common way in the past to get rid of unwanted chemicals) it could cause a huge problem which would certainly result in prosecution as well as a major health risk.

They had Myfords then surely

Thanks for the link Alan.

I think they must have painted all the machinery in gold just for the film - it looks too perfect otherwise.

Thanks Ian - that looks like a great event. Andy

Thread: What to buy

What's the problem with something made in China? You seem pretty vehemently opposed to it.

Mark, did you get a reasonable quote in the end? Andy

Thread: Machine moving recommendations.
20/05/2019 08:28:42

What I did to move the smaller items in my workshop was to hire 20 stackable crocodile crates. Stuff like chucks and vices are too heavy for the cardboard boxes supplied by the removal company. They also hold any oil leaks. The removal guys did moan about the weight of them though which they hadn't really factored in when quoting.

Thanks Clive, that is really useful. Andy

Thread: Machine moving recommendations.
17/05/2019 14:46:45

There is another machine mover who advertises on eBay, if you do a search for lathes their listing will come up. I have never used them.

When I moved house a few years ago moving the workshop machines and the house contents on the same day was a headache as there was just too much to do - and that was less than 1 mile away. So if you can do them on separate days I would recommend it and I would recommend paying someone to do it. The cost of moving house is so high and is so stressful that an extra few hundred £ is a drop in the ocean - at least that was my reasoning.

Thread: Smart & Brown Model A
17/05/2019 14:21:17

Thanks Lathejack and Clive, i appreciate the advice and the offer of the manual PDF. The one I had my eye on is on eBay and is a Mk.1 - looks good condition though. What are the main differences between the Mk.1 and Mk.2 besides the shape of the base?

In terms of weight of this or a 1024 - I can move my Denford around with a pinch bar on my own, albeit its inch by inch - are these movable once they are in place without a big faff? Is there any space under the base to get a toe jack in for example so it can go onto pipes?

Hello

Does anyone on here own a Smart and Brown Model A toolroom lathe? What are your thoughts on it for the home workshop? Apart from the lathes.co.uk site there isn't much information out there.

My current lathe is a Denford Viceroy 280 - I would like a machine that is a pleasure to use but I am not sure if a Model A would just feel very outdated. I have seen a number of people saying they love their S&B 1024 lathes - is a Model A going to give a similar experience?

I enjoyed it today. It is very noticeable compared to a few years ago that there is a lack of traders with new machines on display. Chester had a small stand but no larger machines. No Warco, Amadeal, Axminster or Arceurotrade. I think the only lathe for sale was a repainted Myford. Nothing relating to 3D printing or CNC. If you want to by machine tools these days it seems like the only option is online.

Some of the models are amazing - my favourite was the 1/3 scale supercharged Bentley engine and gearbox.

Thread: Make new crossslide feed screw
02/05/2019 13:04:19

Hello - I am thinking of making a new feed screw for my Denford Viceroy 280 and fitting angular contact bearings and a new handle. The screw has a gear that drives the power cross feed.

My plan is to buy a 12 mm diameter lead screw rod from RS or similar (seems to be about £13 per m and available either in SS or carbon steel) and a new off the shelf gear if I can find one (or cut the existing gear from the existing screw). Cut the rod to length, machine it, fit the gear by pinning it and loctiting it.

Ideally I want a new feed nut as well. Matching bronze nuts (for the rod) costs about £30 but they all seem to have the mounting parallel to the thread whereas I need the mounting to be perpendicular to the cross slide (if that makes sense).

Has anyone got any experience with fabricating a feed screw like this or any ideas?

Any advice is appreciated. Andy

Is it an alloy or CI sump?
