|Thread: Milling cutter advise|
No matter what diameter the cutter when face cutting you are only cutting on a small length of each tip. The larger the diameter the larger the torque required for the same cutting details. I find an 8mm diameter cutter ideal on my SX2P when cutting features in steel generally. Larger diameter may have to be used for side milling to cover a larger depth.
|Thread: Ideal Dimensions of Vice Clamps|
The clamps need a reasonable heel to sit on the table otherwise they will be compressed into the table. A line contact like those Vic has shown will end up marking the table as some cast iron table are soft. Create a clamp with a heel of say 3mm wide.
|Thread: ER 40 Milling nose|
Why not change it to R8. You can hold most tools directly and use an ER holder if required. Putting a thread on the nose risks wear, although in the hobby workshop will outlast most of us.
|Thread: Milling cutter advise|
I have a the same machine but use steel, until recently I stuck with a fly cutter for larger surface widths but now use a 40mm dia face mill. Both are good but the 4 inserts on the face mill allow deeper cuts where required.
|Thread: WHY THE TANG?|
When you consider the amount of tools and holders that are fitted directly to tapers with no other anti-rotation device, then why would a drill tang be considered an anti-rotation device as against a removal device. Drills can be had in all morse taper sizes and each size covers a standard drill range with some overlaps. When considering small drill diameters on a 1MT the drill will break long before the tang twists. I think the tang was an evolution created by some one in the past to overcome the problem of removing a taper that caused less damage then driving a wedge between the tool and the end of the spindle.
|Thread: Problems reading from a 3.5" floppy disc|
You could try a recovery program if it just a case of a corrupted disk not physically damaged. I have done this a long time ago, cant remember the software I used, but have done it with all types of modern sticks and cards. How many reliable data files you can get back will depend on the cause of corruption, it may be just the FAT which is corrupt and just needs rebuilding. Usual WWW search should find a freeware recovery program.
Oh memories. Like most I walked to school and back from about the age of six, traveled on the bus alone from the age of nine to get dinner at my grandmothers when my mother got a job in a department store. No family car so holiday travel by train, on arrival at Scarborough boys with trollies would carry your cases to you hotel. Mornings on the beach then back to hotel for dinner, back to the beach then back for tea and even supper provided.
Used to travel to Nottingham in the fifties and early sixties by train or bus, remember the trolley buses about then.
Father in the RAF for most of the war as an air frame repair fitter. He seems to have visited most large aircraft aerodromes during his time.
|Thread: Hermes Parcels|
Just had a parcel delivered by Hermes, it was an Amazon item but suspect came from China. The date on the package was 27 August, should have arrived 3 September, and Pilot was listed as original carrier. All in all not too bad.
My query is though, my Hermes parcels were often delivered by a pensioner in his electric buggy. The actual Hermes agent was his daughter, how are they insured (or not). Does Hermes actually check that their agents have buisness insurance on their vehicles, not the buggy. To me they cut as many corners as they can at the local level so what is it like higher up the transport chain, I cant say I have every seen a vehicle with Hernes name on.
|Thread: Cutting oil ( Suds) resistant paint|
During my years in machine tool manufacturing we experienced numerous times when coolant reacted with the finish in coolant tanks. We used two pack epoxy on the machines themselves but used specialist coolant equipment suppliers for the tanks etc. We never had a problem with the machines and I don’t know what caused the reaction with the coolant tanks but some coolant acted like paint stripper. If you know what coolant you intend to use then do a test with, paint a bit of metal and submerge in neat coolant to ensure it is compatible.
|Thread: Logging in to MyBT|
Michael. Most likely a phishing email, never use a link in an email to go to any of you accounts or where they ask you to reset access. If you look at an email purporting to be from a supplier you can see things that don’t look right, non UK language phrasing is one and obvious spelling mistakes. I always shut down the web browser and open up again to go to a providers web site.
|Thread: Any vet's/retired vet's on the forum?|
Sorry to hear about your cat. Our vet for many years, we had one then two cats, was very much an animal person, not so much a people one. He was great and charged us peanuts for his services. Then he retired and sold the buisness to an international group that have bought up most local small practices, The prices went through the roof, fifty quid to walk through the door, foreign vets that my wife had trouble understanding and little idea of what was wrong other than the price. When our last one became ill, after spending about £300 at his vets and getting a quote for a £1000+ to explore his symptoms we moved to another local vet. This one has a farm animal practice as well but our practice is run with young friendly vets who think of the owners as much as their animals. Any way within two visits they new the problem and we lost him, but their charges were in the 10's not 100's. What I am trying to say is there are some practices to steer clear of and talk to locals with animals and find their experiences.
|Thread: Logging in to MyBT|
Cant find the email now but earlier this year BT switched their email servers from Yahoo to BT. The switch over created some minor glitches. My normally on Mail failed to connect for a time but did the next day, after a lot of head scratching.
Be careful with any email purporting to be from a service provider, many are phishing, I always view these type of emails in their raw source as this shows the sending IP address, mostly coming from the USA or Netherlands.
|Thread: Faceplate workholding.|
Why not mount on centres and tap a hole off centre to use a screw as a driver. This still leaves the od clear and the part is fully supported.
|Thread: Warco WM180 or Sieg SC3-400?|
I have had a Sieg SC3-400 for over 4 years. In that time I have had no problems with the machine. You have to think of what the average diameter you will be cutting. I am making a 3 1/2 “ loco from stock material an at the moment just machined the smoke box ring at just over 4” in diameter. I had to turn this in stages any way with different setups and allowing the part to cool, not the motor, as I cut with carbide and no coolant. I very rarely cut for a long time on the lathe, even if I am on it all day the cutting time in a single cycle will not be long.
|Thread: 0.8 straight wire|
These supply model shops and I have got wire similar to what you want in the past. Look at the web site and find a local stockist.
|Thread: Surface gauge reconditioning|
Why not scrape them. Good little exercise, I still have my apprentice one from nearly sixty years ago, was well oiled before putting away for fifty years, now back in use.
|Thread: Paint for mild steel sheet brazing hearth.|
You can get a heatproof paint from Wilikinsons, meant for fires and bbq’s. I use it as a simple cover on bear metal while building my loco. It stands up to a blow torch very well, I have brazed bits after cleaning locally and surprised at how much paint remained close to hot area. Sorry can’t remember the name, it is a spray or tin for brushing.
|Thread: Lathe turning speed in relation to different metals|
There is a lot of science involved. Basically it is how the material being cut reacts with the cutting edge of the tool. If you compare the same material with different cutting edge profiles it will give you some idea. Tool manufacturers such as Sandvik have numerous solutions and in production machines it may take numerous trials with a particular machine to get to an optimum tool life. You can search online and find many articles on the science behind it all. With small hobby machines and a single type of tool for everything much is trial and error, what works for doesn’t for another.
Bazyle, you forgot Celebrities, that list of unknown people that think everybody should know who they are.
|Thread: Whats this tapping head?|
It’s a, I assume geared, tapping head. Made as a special to fit on a flanged quill drilling machine probably. The drive input which I can’t see may be a tenon. Used to design these for years in my working life. Don’t know Bush, ,Albert some one near Newark may remember the name. As a total special not much use unless you can mount it and use a single drive spindle to tap with.
