The Warco’s proberbly no cheaper to run as you can do the job much quicker on the DSG. Ian S C

I wish you luck with your DSG 17t ; I can recall working on a similar machine in 1962. and I remember that it was "built like a brick *****" but ran and cut as smooth as silk. The firm is still going strong; a look at their website may be interesting. Ken Preston.

Wow Ray,

Makes my Warco look like some sort of thing out of Noddys toytown. I wish you every luck with it. Keep us posted as to what projects you are planning.

yes I have a 13×42 DSG easy nice machine Has it got graduations on the tailstock

[Ady1Participant @ady1]

Now that's a REAL lathe…makes you go weak at the knees

[Raymond AndersonParticipant @raymondanderson34407]

Mark, yes it has graduations on the tail stock barrel. Bob, my other lathe is a Warco GH750 and it's a pleasure to use never any problem [only ever replaced the halogen bulb] and I have had it since new in about 2000/2001, and I find I still use it more than the DSG!!! although good as the GH750, is when I do fire up the DSG, it's on a whole new level. As far as projects go I don't make any models, I prefer making tools/tooling.

Ady1, You would certainly be weak at the knees if you tried to shift it.

Ken, It was one of my brothers [he's a foreman turner] that found the DSG for me, and you have decribed it perfectly.

Regards to all,

Raymond.

Damn fine machines perhaps the best money can buy.

7.5 pony motor, how you powering it?

[Raymond AndersonParticipant @raymondanderson34407]

Jon,

The DSG is powered by a VFD that has been sized to the motor, the unit is made by Siemens and is 230v single phase in. The drive has to be almost twice the motor power because of the single phase input. The unit was very expensive but worth every penny. The electronics engineers at the brothers work kept me right with the electric side of things.

Regards,

Raymond.

[Raymond AndersonParticipant @raymondanderson34407]

Jon,

Some more info for you, The drive is in 2 boxes 1 about 300mm square and another smaller box about 200x150mm that is connected to the larger one. by a screened cable [but I don't know how many cores, as I have never looked] It was this smaller box that the electronics lad had a laptop connected to. The larger box has 2 digital displays for various parameters and the smaller 1 has 1 display. It would be easier if I had a Digital camera but the neighbour [who's camera I can borrow] is away at the moment. I will post some photo's later.

The drive was very expensive 4 figures,and I don't mean £99.99 but it was the best way of powering the DSG in the absense of 3 phase 415v.

Hope this was of interest to you.

Regards,

Raymond.

One has just went on fleabay for 300.00 in very tatty condition.

I use a 10 hp rotary converter from Transwave cost £1200 which was offset a bit by selling my old one. Nothing complicated to do just wire it in to the main house supply and away you go.

Agree with all that is said about DSG lathes. Find my 17x 72 which dates from 1960 is far more accurate than my Myford Super7. Both have had the beds reground but the DSG is just a joy to use with all the controls so easily to to hand.

As a matter of interest for the last 10 years it has been powered by a home made rotary convertor without any problems (touch wood!) which I switch on and off with a wireless fob.

[Gray62Participant @gray62]

Hi Peter,

What is the capacity (HP) of your homebrew phase converter?

Dou you have any details/diagrams etc for what you have built, maybe worthy of a writeup in MEW

regards

CB

[Peter BellParticipant @peterbell11509]

Hi,

Not sure of the capacity but it will run the DSG and Abene mill at the same time with an input current of around 35a depending on cut. The DSG normally runs around 15-25a again cut dependant.

It;s just a 415 autotransformer and capacitors really but I start the pilot motor in star and then run it in delta using timers to reduce the switch on surge. Unloaded it only runs about 3 or 4a but it runs even small loads like the tool & cutter grinder, log splitter etc very easily and I spent a bit of time optomising the capacitors.
