(it's not entirely your fault Jo).
Hugh, I would like to see those photographs, I got the original (I think) layshaft with mine which I understand is uncommon.
I was under the impression that the high speed version (4,000 rpm) used a hard spindle in bronze bearings but that the standard (2100rpm) used a soft spindle in cast iron.
Mine are both the ME version but the later one was modded to allow for the higher 2100 RPM and less prone to break the headstock if you get heavy handed Jo
AS, What are we looking at, bearing in mind that my experience of electric flight began and ended with a 540 motor and 7.2V nicads (with a Mole charger - remember them?).
Something like this?http://www.hobbyking.co.uk/hobbyking/store/__18178__Turnigy_Aerodrive_SK3_6354_245kv_Brushless_Outrunner_Motor.html or are there bigger, torquier, slower, cheaper ones about?So, if I understand correctly 12v x 245 gives 2940 rpm. 3:1 reduction should be doable.
What would I be looking for in terms of a PSU and speed controller?
Jo, didn't you make headstock oilers for one of yours? Was that the high speed mod you refer to?

Was that the high speed mod you refer to?Yes I made drip oilers for C1, which allows me to work for longer without having to add a drip of oil every 20mins or so which is much better. But I do have to watch I do not knock the oilers off when I use the chuck key. The later machine has flippy cap oilers, they do not hold as much oil but more than adequate for most normal operations. But they redesigned the entire headstock on the later machines, the headstock cast was a bit thin either side of the bearings so they squared them up adding much more material. Jo
AS,STOP right there. This is taking up far too much time as it is .
Quote from: tangler on September 04, 2014, 03:53:23 PMAS,STOP right there. This is taking up far too much time as it is .<sigh> So typical of the youth of today - no time to do the job properly. Now a REAL engineer would be taking moulds from the headstock and digging a mine in the garden to mine the ore from which the iron will be extracted to cast into those moulds. That's the way we'd have done it when *I* were a lad, but these days everyone just wants the instant solution... AS
It doesn't look like the outrunner idea is going to work just at the moment - food for thought though, thanks AS.
The DROs are those as used by AS for his mill, I haven't done the mains conversion yet.
