Not a cheap hobby, is there any hobby that is really cheap, you might say something like bird watching which is alright until you want binoculars then do you pay £10 or £1000, We have to do something to keep all our marbles. When you consider a day out can easily blow through £100, with fuel and food and that is just for two people. Also remember you cannot take it with you.

Like many I keep coming back to this to see if it has been solved.
We know a date 1908.

Do we have a country, UK or USA.?
Can we recognise the numbers in relation to something around at that time which is not relevant now, or has changed significantly.

I have no idea at present but will keep digging.

I used to have one, went the way of most advertising items. Can’t remember where I got mine.

I am signed up with the Government Gateway for when I was self employed. The only details I ever gave were my National Insurance number and normal bank account details for repayment of overpayment. I suspect as others a scam in process, trying to get information for some sort of grant payments, my son in law needed to supply passport information for education grant.

Kluber NBU15, if you can afford it. Seriously what ever you decide to use ensure you keep to the recommended amount according to the bearing type and size. Too much can be as bad as not enough.

If time is money then not as long as if it isn’t.
Material removal rate of machine used is an indicator, then it is up to the operator and his/her reluctance to use that removal rate.

Make in multiple parts to reduce machine time, could be made completely with bought parts fitted together. Cost versus time.

I bought my shed new about 15 years ago, so good test of time. After putting it up I stapled polythene sheet to the inside, I think it was damp roof membrane sheet as it is thick and easy to use. Then I put mineral wool batts between the uprights, both walls and ceiling. Finally I boarded the inside with plasterboard, if I did it again I would use thin osb. Some board got wet when I had a roof leak and replaced the plaster board with 3mm packing ply, the sort of stuff used for making transport boxes, it’s probably the cheapest sheet material you can get. The only thing I haven’t done is the door, but if I spent more time in there I would make better fitting doors.

I think the articles have been transferred to purchasable dvd, free articles are only open for a given time.

Probably not possible but increasing the diameter of the drive and driven pulleys can increase the available grip.

Bill, yes they are used with split sleeves I mentioned, no problem using them in a chuck also. I assume split sleeves are still available from some tooling companies, did find this specification for the drill tang Drill Tnag Dimensions from the USA.

Can’t quite see the detail but I think they are parallel drill sleeves. When using smaller drills, say under 10mm it is cheaper to use tanged parallel shank drills than morse taper. Used a lot in production drilling setups where you have a taper shank spindle. The shanks are specific for a small range of drill diameter and the drill has a pair of flats on the end of the shank which fits into the sleeve for drive, pushing the sleeve into the spindle grips the drill. Specified them a lot in my design days for multi spindle drill setups. There was a similar question some time ago ( years).

Steel is going to be the cheapest material, by that I mean EN1A, 230M07 or EN3B, 0070M20, both in bright not black. Keep diameter down to below 25mm, this will make parting off a little less stressful. Brass is an easier material to cut with either high speed steel or carbide tools so is worth a try but the cost is greater. I would avoid aluminium unless you intend to use it in your work, it appears a lot on YouTube videos as most are from the USA and it is more prevalent there than in the UK, i don't know what the cost is in the USA but in the UK it is more than steel. By practicing on the material you intend to produce items from you are learning about the cutting tools as well as the material as there is a geometry difference at the cutting edges. Also avoid silver steel at the beginning, it is tougher than simple steels so more difficult to get a good finish.

A professional rebuild likely very expensive. I used to work in the machine tool industry and typical costs at the time for rebuilds to new condition but better accuracy, difference between mass manufacture and individual build, was in the region of 2/3rds list price. With hourly rates north side of £100/hour plus parts you want get much done if the machine has to be stripped, repaired, and rebuilt with paint. You may find someone with the skills but not the tools to do a sympathetic rebuild without major refurbishment. Perhaps take the insurance money and do what you can yourself.

i used to work under a technical director, a doctor of engineering, who used to carry a six inch slide rule in his jacket pocket. Whenever he was asked a mathematical question, usually regrading hydraulics, he would go straight for his slide rule to perform the calculation. While he slid his rule I would perform a mental calculation and give him my rounded answer which he would eventually agree with.

Perhaps as with the discussion on Hydrogen central heating system we should move away from battery driven calculators and revert back to mental arithmetic with slide rules and log tables. Perhaps teaching maths without electronic aids is due a come back.

How would the disk be used? If it is used for small data file just backup/copy the files changed. A full backup of all the data on the disk is not necessary on a daily basis unless used on a multi user access setup.

I assume you are talking of the NHS app not the NHS COVID 19 app, they are two different things.

I installed the NHS app as this is the one that gives your vaccination details, amongst many other details of you health records. You may be able to install the app then register each of you independently to use it. The registration method I used uses photo id for the initial setup, some form of photo id then a selfie. As previous have a google.

Use a fixed centre on my SC3, slide the tailstock to part for light end force, lube with oil. As long as cutting forces on the part don’t bend the part or force it away from the tool then support should be enough. A live centre should be centred with enough force to make it turn with the part. Always check for heat in both the part and the centre while in use, particularly with higher speeds, obviously that all depends on size of part in relation to the machine. I have burnt centres, many years ago, you learn from your mistakes, we hope.

I have just fitted magnetic with Eason display from Machine Dro. Magnetic are smaller then optical and more resistant to coolant etc. All the information is on their web site. I did fit a cheap scale on my previous mill but it only lasted about eighteen months when it started reading randomly even though no damage was evident.

Grip a diameter in the jaws while machining, this will ensure that the jaws don’t rattle about and are forced to the correct side of the scroll wether for inside or outside holding.

Looking on Companies House, the company does not have John as an officer of the company, so probably just slow in replies.
