Thanks Steve, I'm in no hurry, so will wait and see if they reply. They are now selling on ebay and don't even respond through that medium,,,

Matt

Steve,

I've never really looked at the PeWe site and they offer some interesting accessories. Like Paulimot, PeWe are based in Germany so you can get them delivered without the worry of of import duties etc. (until Brexit changes things!!)

I also notice they do a holder to hold a die grinder/Dremel type tool - could be useful for internal grinding etc.

I still suspect that most of these units are all made by Create of similar in China.

Create do a retracting toolholder but I can't get any response from them...

Keep us posted.

Matt

The only thing to check for is that toolholders fit when they arrive. I think quazlity control can be a little poor. I bought a few from Create Tools last year and one didn't fit very well. I also have an original Multifix and all the holders seem to be interchangeable.

Matt

Can I suggest Paulimot

I have bought Multifix from them in the past and prices are comparable to Create Tools (who probably make them)

Delivery for my last lot (Size A) was free and took a few days by DHL.

BTW, I still can't get hold of Create Tools who make a retracting toolholder - mind you, they are based in Wuhan!!

Matt

The topslide has that feature already (Std o the VSL) It can be adjusted whilst in the lathe so a nice feature. I actually want to make a new set for some castings I have.

The cross slide is nut is very slim and there is no realy way of doing this mod.

Matt

Hi,

Does any knowledgeable person happen to know the specs of the threads of the top and cross slide screws? They are trapezoidal but I'm not sure of the sizing.

The plan is to make some new nuts myself.....

Matt

Hi,

Has anyone been in recent correspondence with Create Tools in China (The manufacture Multifix type tool posts & holders). No response to any emails from myself.

I am aware they are based in Wuhan so I was wondering if they are currently operational.

Matt

Clive, That is interesting as my Doc has never mentioned about potassium with Ramapril medication. Off to google it now....

Clive, there's a new venture for you!!

Matt

Robert, I'm in Sout Somerset, near to Yeovil.

Matt

Brian, I think I have one of those somewhere - will expeiment over the next few days.

Matt

Clive,

All interesting stuff.

The motors are, I believe, as follows:

The main motor is a dual speed 0.5hp/1.5hp 415V_ac 3 phase motor.
The speed change motor is a dual voltage (240V_ac/415V_ac) 1/20hp three phase motor.
The coolant pump motor is also a dual voltage (240V_ac/415V_ac) three phase motor. ( don't use mine)
The carriage feed motor is a 90V_dc motor.

The issue with the main motor (so I am being told) is that is is fully balanced and thus not a good idea to replace.

Matt

Mmm, it;s the same reply most of the time - "ought to be OK but..."

The 10HP verion is eye watering in price and definitely a no no.

Matt

Andrew, Dave frm Direct Drives says that I can operate it this way. (DRO's are powered separately)

Anyway, I'm glad you have a firm graps of electronics, unlike me!

Matt

Dave, you are so right - all cloaked in mystery!!

If I could find the surge on start up in high speed, then all would be easy to ascertain. Personally I'm sure the 50% overload will be fine but I thought I wouls try and find out if anyone else had gone through this process.

Matt

Robert, they appear to be quite different. The Digital phase converter is 'plug & play' and it means I can change motor speed and operate all 4 3 phase motors on the lathe without issue. If I used VFD's I would need to completely re-wire the machine. I'm looking at their 5HP unit.

This is an example of the 5HP unit: **LINK**

Matt

Before I go any further, I am asking about a Digital phase converter rather than a VFD or similat inverter.

I currently use a rotary converter for my Hardinge lathe but (no matter where I place it) the noise is just a little too much for me so a while back I considered a Digital option from Drives Direct. Lathe itself is fairly quiet.

My question is whether a 5HP unit will be OK for the startup surge of the Hardinge (the main motor is 1.5HP) or has anyone installed one of these units? It is a big chunck of money to 'experiment' with and to go to the 7HP unit would mean I have lost most of my limbs in payment! Dave at Drives Direct has not shipped one to a Hardinge user and so can not advise.

Matt

Bruno,

I thought it probably easier in the first place that I PM you but discovered I can't. Can you email me on: matt@clockworld.co.uk

yes, I'm about to embark on finishing off a partly well made version. Need to get my head around the boiler and pipework,

Marr

Er, I'm a little worried now, probably about 20 in one drawer and then I realised all the copper/hide ones. Then let's not forget all of my tiny watch/clock ones. Oh and what about all my lump hammers, sledge hammers, brick hammers....(and I also have not included mallets!)
