|Thread: J&S 540 way lube question|
Did not think J&S would bother making a pump for themselves, but like electrical components would simply buy them in from a specialist company. I know of Andmar and visit their website, but like most machine tool spares companies, their website is not very good.
I will email them and see if they can help me with a few bits and bobs i need.
This is a good thread, information on The Jones and Shipman surface grinders is scarce and difficult to find. I bought a 540 last year and am waiting for this lockdown to finish, so i can get it painted and reassembled.
Does anyone happen to know if the Hydraulic pump in the base that powers the table, was made by J&S, or did they buy them in ? I need two copper gaskets for mine.
|Thread: 316 Stainless|
I used to machine, and fabricate and weld the 300 series stainless steels a lot. it work hardens very quickly, so you need to push on and not let the tool rub or it will become a nightmare to work.
|Thread: The Current War (Film)|
Yes, Tesla was an actual engineer, but a bit of a recluse, its only at this distance in time we can see how good he really was.
I was reading about Sir Joe Whitworth a while ago, he was another borderline nutcase , he fell out with absolutely everyone he had any dealings with, notably Armstrong, his former friend. He could cause a row in an empty house.
George Stephenson, was very good at claiming others hard work as his own, such as the laying of the railway over Chat moss when really it was Joseph Locke who devised how to do it. Stephenson was also good at, if anything went wrong, blaming everyone else.
Henry Ford and his well known anti-semitism, his private "security" guards and his controlling ways ? Hitler actually based a lot of his ideas on Fords scribblings, and the gestapo were modelled on Fords security force. There was a brilliant documentary about Ford on PBS a while ago, if Ford wanted to get rid of someone from his employ, he would set his thugs to bully him into leaving, and then he would be dragged into a secluded place and have the life half beaten out of them.
Ethics in Business, what was the name of that delightful chappy who fell off the back of his yacht about 30 years ago after raiding everyones pension fund ?

|Thread: Boring Head|
Buy a decent one too, the far east import ones can have dials that mean nothing. I have one here and its neither metric or imperial, i should chuck it in the bin ideally. I bought one made in California, Criterion i think and its miles better. You get what you pay for.
|Thread: 3 phase - radio puzzle|
I have a old shortwave receiver in the shed, normally on the 20 meter amateur band. I noticed the other day when i powered up the vfd on the mill, it sent the receiver haywire, couldn't hear a thing.
|Thread: The Current War (Film)|
I think Edison was a bit of a gangster to be honest, ethics and fair play were not things he let bother him too much.
|Thread: "I'm calling about your accident" - how does this scam work?|
I remember see an american advert for an ambulance chasing firm of lawyers, many years ago, and thinking how appalling it was. Someone said to me it would be like that here in years to come, and low and behold, it is. No morals or ethics. Same with this "ppi" rubbish.
Is it one of these reverse the call charges scams ? The longer you keep chatting the more you pay ?
|Thread: Wiggler or edge finder?|
I have a Starrett edge finder and swear by it. Use it all the time. I have a cheaper one but its not as good. if you have a look at the sururban tool channel on youtube , they do a test of the various types, the edge finder wins it i think.
|Thread: Electric Cars|
I tend to agree. The modern world that everyone in power seems to be striving for, seems a boring, clinical place.
|Thread: Lack of Quill on Milling Machine|
My Tom senior has a vertical head, a head without a quill and it was a pain to use. The vertical head was merely an add-on to update a machine that was outdated, a horizontal mill. Another issue to me was the huge lack of travel in the z-axis, about 4-5 inches between the cutter and the table top, maybe ok for very small work, but hopeless for anything else.
My solution was to graft a Bridgeport varispeed head onto the large cast iron overarm. Its transformed the machine completely, i have much more space under the head, can drill holes at an angle if i tip the head, its been a worthwhile project.
I think scraping as a process has been put up on a pedestal and is being worshipped as a "long lost black art" by some. I think its like filing or hand fitting or something similar, not a process that is to be feared or to be overawed by. But to be undertaken with patience and common sense.
|Thread: Chinese tacho - beware|
Quite a lot of the large motor manufacturers such as mercedes, BMW etc, have factories in China to make components, or complete cars for those regions. Triumph motorcycles are touted as being made in England, but again a lot is made abroad, Malaysia and India i believe, frames, suspension components, switchgear etc. The design and engines are made in the UK.
So saying anything is rubbish because its chinese, or made in the far east is fraught with danger.
|Thread: Is this cheap type of VFD worth buying?|
I have to laugh at people slagging off chinese electronics when probably 90% of electrical devices are made there. The high end Apple £1,000 phones are made in china, as well as the rest of their range. Televisions, computers etc etc. I bought two vfd's made by huan yang for the surface grinder, set up was easy and they work fine, and did not break the bank.
|Thread: Dro scale positioning|
Got the dro kit delivered yesterday. Popped out to the shed today and had a quick look, i don't see any way to mount the scale on the front of the table. Looks like i will have to mount it on the rear and lose a bit of movement in the y-axis. There is simply too much going on, on the front of the machine, with the powerfeed limit switch, oiler, and the nut that clamps the table in place (its a universal).
|Thread: Chinese carbide inserts.|
Doubleboost on youtube does reviews of banggood tooling. Most seems ok, especially for the price. The problem i have is the very long wait for the goods once you have ordered them. I am waiting months now for a set of parallels for the mill.
|Thread: Dro scale positioning|
Yes John, that looks like a solution, something i will consider when i get the dro kit delivered, I have enough movement in the x and z axis, but always found the y a bit limited and don't want to lose anymore if at all possible.
Just splurged out on a 3 axis dro kit for the Tom Senior. It seems that the way to mount the x-axis scale is to mount it on the rear of the table. This is going to reduce my meagre y-axis travel by an inch or so, which i don't really want to do. I was thinking of mounting it on the front of the table, but this would interfere with the limit switches for the x-axis power feed.
Anyone any novel ideas for mounting this scale without losing y-axis travel ?
