Thread: Help choosing a Chinese lathe please
02/09/2019 22:47:22

Neil

The machine mart lathe looks expensive in comparison to other brands.

I bought a mini lathe about 18 months ago and spent a long time comparing specs etc.

In the end I bought a CJ18a lathe from Amadeal. It doesn't have the brushless motor of some of the Chester or Warco ones but has a 100mm chuck as standard. It was delivered very quickly. May be worth considering.

It's not just ARC. I ordered two items last week , one from Warco and one from Amadeal. Both were ordered late on Wednesday evening and both were despatched on Thursday and arrived on Friday.

Thread: Which Stuart models can be done on a 7x14 lathe with no mill?

For information, there is an Amadeal cj18 lathe for sale at the moment in the 'for sale' ads on this forum.

Thread: Need to drill a hole digital caliper
07/06/2019 15:10:03

I had the same problem. I used a tungsten carbide drill bit from this range: - **LINK**

I tried a masonry drill and it did sort of work but not as well as the tungsten carbide bit.

Thread: Where is best to buy??
03/06/2019 13:47:40

Macc Models seem to have good prices for small section brass. 1/4 inch brass hex is 90p for 12 inch length, but postage is extra so for a one off piece would probably be more than you paid.

No assocition with the company, but I have bought from them. Quick delivery too.

Thread: Connecting a pair of motor controllers.

Does the potentiometer have a switch? If it has 5 wires it could have 3 for the potentiometer and 2 for a switch.

Thread: Should I have 3 phase supplied to my house?
30/05/2019 11:44:27

A similar question was asked on this thread:

https://www.model-engineer.co.uk/forums/postings.asp?th=138585

some of the comments were incorrect, but you may want to have a read. Some comments were from forum members who have had three phase installed.

You can get a quote for 3 phase by contacting your electricity distribution network operator (DNO). The cost will depend on the location of the nearest suitable 3 phase main cable and the supply capacity you want . If you don't know who your DNO is, you can find out at this website:

Regarding your own internal wiring, a commercial/industrial electrician will be able to quote for the necessary work.

I suppose it depends how much you want to spend.

Here are links to 2 suppliers of steel cabinets:

Glasdon

Or you could make a brick cubicle with a concrete flag as a roof.

It may be that your leds can be dimmed if you have dimmable leds and the correct type of dimmer. This is one I bought recently:

Dimmer

specifically advertised for leds.

Thread: miniature 3 pin sockets
27/03/2019 23:39:42

It sounds like Mini Din connectors would be a good choice if they are small enough for your application. Available from 3 pins upwards and with chassis or pcb mounting sockets. I buy connectors from CPC. They are local to me but do quick free delivery. **LINK**

Thread: Making nameplates
13/03/2019 21:57:35

The etched brass in my previous post is 28mm diameter.

13/03/2019 21:55:48

I etched this after using pressnpeel sheet with the design printed using a laser printer.

I heated the brass in the oven and then pressed it onto the sheet.

I used Sodium persulphate from CPC as the etchant. It is clear so is easier to see what's happening than ferric chloride. It works best at 50 deg c.

13/03/2019 21:04:57

You could try Pressnpeel. It is a blue sheet that you print onto using a laser printer or photocopier. You then iron onto your brass sheet and when peeled back it leaves the black resist for etching.

I have used it for producing PCBs but recently made a couple of etched patterns onto brass for wood brands. I didn't manage to etch very deep, but deep enough I would think for a loco nameplate. I intend to use this technique to produce nameplates for my 16mm scale loco.

Thread: Metal Cutting Power Saw
11/03/2019 22:53:48

Ron

The Evolution Rage saw has a TCT toothed multipurpose blade not an abrasive one. I have a Fury saw which also has a TCT toothed blade. I have used it mainly for wood but have cut 1" square section steel with it. I have had it for about 4 years and it still cuts ok with the original blade, although I have cut steel a few times. I bought it after a demo in my local B&Q where they cut steel and aluminium.

Were they all put in at the same time? Methods, regulations and materials change with time so some parts may be to later regulations. Old setups may be left untouched until a repair is done at which point the latest regulations will apply.

Martin C

As Martin says, it is most likely that the line all the way from the pole transformer was originally bare wires but that work on the high voltage line (or at least the transformer pole) has been carried out later. Possibly refurbishment / replacement which would include replacing the low voltage wires with insulated Aerial Bunched Conductor (ABC) at that pole. The rest of the low voltage line could have been replaced at the same time, but cost or company policy or technical constraints may have meant that the minimum was done.

I seem to remember in a book on the SOE reading that they employed various artisans to make complex timers and guidance systems for secret weapons in a house somewhere, but annoyingly my memory has deserted me as to the book.
