|Thread: Looking for a Sharpening Service for End Mills & Slot Drills please|
Unless they are very special cutters, is it really worth paying £3 - £10 for resharpening when new cutters won't cost much more, if anything, with careful shopping around?
|Thread: Harrison M300 advice|
This is the best I can do. I sold the lathe a couple of years ago.
From memory, the angle of the V is 70 degrees, but you had better check it!
Here's an auxiliary boring table that I made for my M300. Clamps to the cross slide with wedge blocks as per Harrison's design. Plate was ex 12mm and screw holes are M10.
|Thread: ME handbook Capstan and Turret Lathes|
I also have a copy but postage from Ireland will be quite expensive. If you can wait until July time, I will be in Blighty then if you haven't been satisfied beforehand.
|Thread: High Speed Bench Drill?|
Send me a private message with your email address and I'll send you all the info. There is too much to put here.
It uses a linear bearing for the vertical slide. The screw holes are spaced to accept a Myford vice and extra counterweights are available to maintain a neutral balance. It mounts on the milling machine table or in the main vice easily. It may not suit Barry's requirements for the high speed but Mike mentioned a very valid point about sensitivity.

|Thread: Help with choosing band saw|
I would second JB's opinion of the Femi bandsaws. Stakesy's was the cheapest place when I was looking and service was also good.
|Thread: Thread with steep helix angle?|
Here's another way to make a rope knurl
|Thread: Help with Excel|
At long last, I have machined the .375" concave radius in the parts that I was making.
Thanks to all the suggestions and help offered.
|Thread: Ortec Digital Read Out|
I remember those units. The scales were sourced from computer printers, but not sure about the box of tricks, but probably used some of the electronics of the printers of the day.
Doesn't help with your problem, though.
ps Sorry, I've just noticed MG's post above!

|Thread: Help with Excel|
Well, there's plenty of food for thought in those replies!
DC I know where you are coming from, but although I'm not good with maths I can use a calculator to convert from Metric to Imperial. In the end, I doubt that a thou or two either way will be noticed after it is covered in paint. Thanks for the links.
JB Following a suggestion, I'll use a button tool to do the cutting.
Bernard. I'd thought of using a graver but access is too restricted (There are actually two parts end to end, to be split later).
John, I need help with both formula writing and the spreadsheet. Andy says he will send me a spreadsheet, so I'll see how that goes before getting back to you.
I need to machine a .375" concave arc in aluminium.
I consider the radius too large for a form tool because there is not a lot of metal to hold in the chuck, although the small end will be supported by a centre.
So, I would like to create a table in Excel to give me the cross slide and longitudinal infeeds. The tool width will be 3/32" and the curve will be smoothed afterwards with a file and emery cloth.
Searching Google, I can only find info on drawing freeform arcs. Can anyone explain how to make the required table, or point me to an online instruction. I don't have any CAD programmes.
|Thread: Contacting YouTube contributors|
Is it possible to send a private message to a YouTube contributor?
I would like to make contact with barumman, who I believe is a member of the SMEE (and may be also a contributor on this or other model engineering forums).
If anyone knows of this gentleman, would they please point him in my direction.
|Thread: Recomendations for a Keyless Chuck?|
The only disadvantage of a keyless chuck over a conventional type is that when used in the milling machine, a lot of headroom is lost.
Maybe not an issue on larger machines, but it needs to be taken into consideration on smaller hobby type mills.
|Thread: A great Victorian BRITISH Scam!|
The wife of an acquaintance in Oregon has a collection of more than 100 sewing machines. All different shapes and sizes. All fully working and like you, I was amazed in the quality of the workmanship of the period.
|Thread: (again) buying new European made lathe|
I have a Wabeco milling machine. I bought it in favour of a far eastern equivalent because of where I live and I liked the idea of a 5 year warranty and 'German' quality. It was nearly 3 times the cost of the equivalent far eastern machine.
My machine was made in the far east and finished / checked in Germany. It was about 2 weeks over the 5 year warranty period when the European built-in inverter blew up. The UK supplier of Wabeco tools wanted £1000 for a new motor/inverter combo. What I did was buy a separate inverter for 25% of the price and wired it into the original motor. Still going strong.
Moral of the story: Just because it is labelled as 'Made in Germany', or wherever and there is a long warranty period doesn't make the tool any better than a far eastern machine.
|Thread: Plans and castings|
Or, if you fancy making a Stuart engine, look on eBay for the castings. That way should get you a set at a lot less than what Stuarts are asking. If they are being sold without drawings, these are available from Stuart Models. Other designs also frequently come up for sale. Probably best to avoid part built engines, at least to start with - you never know what horrors you may come across.
|Thread: UK fires up old coal power plant as gas prices soar|
10 years or so ago, there was an experimental tidal generator in the Bay Of Fundy (Canada). Talking to crew members of the support vessel, they told me that the generator lasted about 6 months before being destroyed by boulders being washed to and fro on the tides trying to pass through the generator. Apparently, it did produce good quantities of electricity when it (briefly) worked.
On one of the previous posts about Pumped Hydro, this system, but using sea water, has been working in Okinawa for about 20 years. There is a plan to copy their design in Co. Mayo, Ireland where a lake 150m above sea level is located very close to the sea. Like most things in Ireland, it might get built one day after all the bureaucratic interference has been overcome.
