And for those of you across the pond a fag packet over here is the common term for a cigarette packet, not anything else!
Thread: DRO on a Mill/Drill?
23/09/2011 17:32:27
I have fitted this head http://www.warco.co.uk/digital-readouts--scales/293-digital-readouts.html to the Warco economy mill with simple scales and have been happy with them. Since fitting them I have found them very useful. I to have wondered about going for a more expensive option but decided against it because of the cost. If I need to put holes on a PCD I will jsut work out the coordinates and do it that way.

Thread: Bridgeport Milling machine help

Paul says it is a 50K Ohm potentiometer, you have fitted a 500 ohm pot, this may be the issue, is it possible to try that?

Thread: Linked drive belts from RDG

It might be easier to fit a T-Link belt if you can find a supplier of small quantaties, the rivet type links can be awkward, however thaere is probably a cost implication.
Thread: Motor as Dynamo/Generator
06/07/2011 12:38:01

Have a look at the Stuart Turner dynamo . Not available anymore (?) but very easy to make something similar and this design gave a useful output at relatively low rpm . The main reason for its sucess is that it's armature and magnetic circuit are relatively large diameter and with a lot of iron in them . Another attraction of this design is that it looks something like a real generator of early days and its size is in proportion to the engines likely to drive it .

 

Look at Forest Classics, they sell a dynamo that looks like the Stuart Turner one.

Thread: rotary tables
31/12/2010 10:34:26
If you are getting a rotary table that can be used vertically then remember that it means that the item being machined is 3" or 4" of the table, just make sure the mill has enough vertical travel to allow for this.
Thread: Boxford spindle speeds
10/12/2010 16:59:04
Andy,
 
That sounds exactly like the information I need. I assume the motor on the 3-phase and single phase machines run at the same speed, if so you have answered the question.
 
Thanks,
 
Baldric.

I have a single phase Boxford AUD MKIII but the speed plate is missing. Can anyone post a picture of this or let me know what the speeds are please.
 
I have tried to post this to the Boxford Yahoo group, but until you are know your posts are moderated, after several attempts over a month I have given up trying there.

Thread: Boiler for Stuart 10v
07/07/2010 13:10:57
thanks for the information, the GLR kits seem about right for my requirements, not sure if I will get flanged plates or not, the actual flanging does not worry me, more that I end up with formers I have no use for. Has anyone built one of these boilers, if so what do they think of the kit.
 
The Idris lubricator looks like what I need.

Can anyone recommend a suitable boiler for a Stuart 10v? I am looking to either build one from scratch or a kit as a learning execise before moving on to other larger projects so do not want to just buy one.
 
Also does anyone know of a source of plans for a simple displacement lubricator that would suit the above engine?
 
Thanks,
 
Mark
Thread: Beginners start here in Model Engineer

Hi There
I have received a phone call from a reader saying the Beginners' page in Model Engineer concerning the Stuart 10H and 10V is to advanced for the beginner.
What do other members think? Am I making it too technical?
He thinks I should not be using a mill as beginners don't have one.
 
regards David
 
 
Since this thread started I have not seen any further articles in Model Engineer about it, are they going to continue as they seem to stop part way through.
Thread: MEW 162 - Phoenix Battery Drills
18/03/2010 13:33:14
Posted by Peter G. Shaw on 18/03/2010 12:21:48:
 
Incidently, whilst I haven't looked at the idea in any great detail, just suppose, the mains plugs and sockets used for the drill were wired the opposite way round to normal, ie the socket wired to the drill. This would mean that it was impossible to connect such a drill directly to the mains, would it not?

 
Not a good idea, just changes what can be plugged in, in this case the battery. There is also another amins connector type see here. This is/was used in the broadcast industry, problem was that the BBC used it the other way round to other comapnies, so hired equipment was a bit dodgy, but there again only engineers had to deal with it and no one was killed!
 
My take on this is that for an experiment it is OK, but there ought to be a warning against it for long term use, just use a different connector.

Quite a few begineers do have mills as they are cheap, or have lathe/mill combos. I liked the way that with the base plate you showed machining it in the different machines. I am actually waiting to see if you suggest a way of machining the main support for the vertical engine in the mill as I would guess this would be easier if you have both machines available.

Thread: Humidty
08/10/2009 13:47:35
I remember someone mentioning somehwere that a dehumidifier in the workshop can help keep rust at bay, but on a timer is no use, it should be on a switch that comes in when the humidity reaches a certain level. Does anyone know where to get such a switch, preferably inline like a timed switch.
 
Thanks

Thread: Rivets and Riveting
07/07/2009 13:28:06
I was just going to post the same company website that has details on rivets.
It is worth noting that the length can vary with diameter, for example look at the small and large diameter snap heads.
 
One thing to not with hot riveting is that as the rivet cools it pulls the plates closer together, when doing large rivets you can hear this happening even if fully bolted before hand. With small rivets the heat will be lost to the surrounding material very quickly so may be of minimal benifit.
