Thread: Hello from Norfolk

Hi Jon

NR16 any use?


Thread: Should I have 3 phase supplied to my house?
30/05/2019 10:00:55

As others have said - It all depends on where you live. In our last house, a new 240v supply was required before completing the driveway. This was modified to a 3 phase supply for very little extra.

However when we moved to rural Norfolk with it's existing 63A single phase supply, the quote was £65,000 for 3 phase. This was out of the question, but they did condescend to up the fuse to 100A, when re-routing the 240v.

A rotary converter was circa £1000. This runs the mill alright, but I find the noise excessive, even when moved next door to the workshop.


Thread: Learning CAD with Alibre Atom3D
28/11/2018 15:29:43

Not quite how Google operates, but if the Alibre web address was entered into the search box, the MEW link would never show, although the proper Alibre site could be accessed.

However if the same address was typed directly into the web search box (top left hand corner in I.E.9) I was taken straight to the correct link.

According to my interpretation of the blurb, you can install on several computers, but have to use the key with the computer you want to actually utilise. Not really a problem, as you cannot be in two places at once.


Thread: What did you do Today 2018

In an attempt to try and find things when I need them, my "system" is to have various heights of 600x400 plastic trays positioned in modules with the locations shown in a database on the PC.

A requirement for a mobile module had arisen and it was completed today.

These are my original static modules made for the old workshop

Most difficult part was trying to work out how to post text and pictures. wink

... and does anyone else remember the plastic-handled round files, which could be bent to shape ?



Like this Michael?

Thread: Knurling tool design & wheel size
14/06/2018 11:21:05

I made the Hemmingway kit some years ago. If my memory is correct, the actual wheels are a bit of an oddball size and the choice of knurl is limited from Hemmingway. However choices were available from Cromwell Tools.


Thread: Glow plug lengths
11/04/2018 23:09:21

.... The longest plugs that I have are the Model Technics 4stroke type. They have the same thread length, but have a bar across the bottom.


Those are what are called Idle bar plugs. The idea being that the hot element is screened from the incoming fuel charge by the bar, as in a 4 stroke engine there are only half as many requirements for Glow as the two stroke.

. No access to a milling machine atm so did it 'old school' with much hacksawing, drilling and filing.

Looking good. Now that is what I would call serious dedication. yes

I'm enjoying this riveting experience.smiley

I don't know why people insist on manual gearboxes just as I don't understand why so many people insist on reversing into side-by-side parking spaces. In that instance, I drive straight in, stop the engine and get out. Each to his own....


Interesting observations. I'm entirely with you on the former, but have to disagree with the latter....sometimes. We were always taught to park with the vehicle facing 'outwards'. So in cases of urgency, a safe and quick exit was possible. I could just imagine the pandemonium if, for example, fire engines had to reverse out.

But...on a visit to B&Q frinstance, it makes sense to have the boot of the vehicle easily accessible by parking nose-in.

Greetings too, from just south of Bunwell.


Thread: mitutoyo digimatic micrometer 2293-766-10 instructions
20/02/2018 15:49:09

My Mitutoyo is the 293-605 version which reads to 0.001mm. When replacing the battery, the Zero/ABS and the Preset buttons have to be 'played with' to ensure readings are correct. Press and hold the Zero/ABS until the screen shows all zeros, then the Preset button. The time interval to press-for varies with what you are trying to achieve.

The mechanical correction is carried out first, as others have described, with a small C spanner, then the screen display altered to match.


Thread: What did you do Today 2018

Thanks for your comments Martin. I did ponder for sometime as to what size to make the holes. Settled for 26mm to just catch the bottom of the taper. In these particular holders the holes could be somewhat bigger so the tools settled past the taper, but that would be no use for the ordinary collets, as they would just fall though.

The material is water resistant mdf as I find that a lot more stable than the ordinary brown stuff, especially in an unheated workshop. Excellent point made about oak, diabolical for steel tooling.

Finished a couple of holders for my R8 tooling which had been scattered around on a piece of ply.


Thread: Newton Tesla Electric Drives

Another of the small advantage of the NT 3 phase system is when changing gear. My lathe manual states the motor should be stopped when changes are required. Unless the gears are perfectly lined up, changes can be somewhat difficult. Whereas winding the revs down to minimum, almost stopped, means the gears just slip into engagement.


Thread: Metal Bandsaw - quality?
08/01/2018 14:22:11

I've had the Femi 2 speed for many years. I first saw it demo'ed at one of the ME shows at Ali Pally. The vendor was cutting 1mm slices from a circular bar of 50mm steel....


Thread: How effective are phase converters
08/01/2018 10:26:09
Posted by John Haine on 08/01/2018 08:54:42:

More than one post on various threads here talk about sharing inverter across several motors. And vfds can be had relatively cheaply on eBay. Time to bury the rotary converter imho.

That's an interesting observation. Would a vfd supply allow the powered drawbar, machine light, and X drive motor to used without the main spindle motor rotating?

My machine (in gallery) was only available in a 3 phase version unfortunately. The pic shows the rotary next to the machine, before the noise became too intolerable.


07/01/2018 16:47:41

Another vote for a Transwave rotary. The local electric company wanted circa £65K to supply 3 phase. I was a bit lucky in getting a 100A main fuse in place of the 63A. surprise

The inverter works very well, it is not load dependent as are the static ones. Have to agree that the only downside is the noise of the thing. I moved it to another room, so not quite so bad. Just turning the radio up a bit, helps though.


Thread: MEW263 - Postal non or late delivery?

They are all sent out together, any differences can only be down to the Post Office.


I thought Gary was on to something with his W & S, but BB knocked that one on the head. surprise The difference in PO efficiencies is interesting.
