I cant wait to see this finished.....

I've watched the vids John posted on Youtube, machining the parts 'n' all....quite entertaining too  :lol:

Bob,
I hope you get a lot of enjoyment out of using the machine as much as you have had putting it together...

hi all well the extension fits but im going to have to make it lighter so this will involve cutting it in have then boring etch have out then welding them back together that ant a problem all that needs doing gnaw is make a stand for it sort out the electric's on that point dus any one no the type of capacitor needed for the motor the one that's running it at the minute is my sper one of my lathe any way pics as promist

Bob,
For the capacitor,
Do you have any details on the motor you could post up please

Looks good Bob , why do you need to make it lighter?  Is it not raised a d lowered by screw mechanism so would lift ok and be more rigid ?
  Keep up the good work Bob , it's almost done  :thumbup:

yep its raised by a screw but its jamming on the Colom not a problem going up  but jams on the downward move support the mill head not a problem I don't think I will loos out in boring out the middle  will still have a wall thickness of 30mm carnet go bigger as it will go in to the slots that john made

That's some extra reach you have there.

I think I may settle for half as much.

Sorry can't help with the capacitor details, my EMCO is three phase.

hi all just a bit more clocked the head in tonight I had to put sum 0.25 mm shim in the top you will see them in a pic to tilt the colam over to clock it in put the vice on and clocked that in to I need to make sum t nuts up right the in fo  on the motor is sa follows TYPE AOR-63-4
D/M 0.18 volt 440 amps 0.55    55Hz U/min 1380 KW 0.24   N.R 617103 and the make of the motor is wiener starhstrom  werke right pics

Bob,
For your motor capacitor, you most use an Steinmetz connection, the capacitor value could be calculated by the following:



C = 36*P* [(220/U) Squared] * 50/f where: C is microFarads, P is motor power output in kW, U is the single phase voltage and f is frequency in Hertz.

Bob,

Doesn't the cap you robbed of your other machine have a value marked on it?

Is the motor definitely three phase?

I'll do the calc and tell you the value of the capacitor you need....

Ok,

Rule of thumb is 70 mfd per 1kw ......
If the kw rating of the motor is 0.25 kw, then a 22mfd capacitor is what you need...but it must be rated for 250v AC....

The info I have on my EMCO indicates that they come in two versions (electrically).

The single phase 0.16 Kw (0.25 HP)

and the three phase 0.25 Kw (0.34 HP)

I have the parts list and exploded drawings for the machine if you need any parts info.

Dave.

hi all thanks for the help on the cap the one that's on that's off me lathe can not tell watts printed on it cos its all bin rubbed off lol but the lathe motor is bigger    there was a chap on the bay selling the two of them I.E the one for the lathe motor and the one for the mill motor I sent him a email asking if he wood sell me the one for the mill or give me the info of the one for the mill  but got no answer back er  don't think its 3 phase as its running on 240 volt

If it's 440v it must be 3 phase Bob
