Denford Viceroy knock-off trigger concept

Hi The carriage on the Denford Viceroy features a knock-off mechanism that can be used when threading up to a shoulder. When the bar is pushed by the stop, it knocks off the half nuts. The problem with this mechanism is that the exact knock-off point is not well defined. The knock-off is more like a...

Re: Backplate thread?

Hi
The tap idea sounds like a good solution.
I think of the thread as a rotary Vee. It has a major influence on chuck runout.

Is yours a metric or imperial lathe?

Re: Viceroy TDS1/2 PCS power feed

Hi
I think it is located in the gear set on the gearbox input shaft. From memory it is a length of 3mm dia mild steel.

Re: Backplate thread?

Hi With any error in thread pitch, you will end up with (nearly) all of the engagement happening on a short length of thread. As a result, there is a significant risk of plastic deformation of the lathe spindle thread. Any sort of deformation of the spindle thread is going to hurt accuracy. I recomm...

Re: Viceroy T.D.S 1/1 G.B - All finished

Hi
From memory, the shear pin can be found on the gearbox input shaft. This is on the left hand side under the hinged cover. Remove the twin gears to access the pin. If I am wrong, just let me know.

Re: TDS 1/1 Tooling size

Hi
I have standardized on 16mm tool holders for carbide tooling. I still use HSS a lot. I prefer 5/16 or 3/8 for that.

Re: Viceroy T.D.S 1/1 GB Apron Reassemble

Hi The apron is definitely made to hold oil. The gears dip into the oil and carry it up into the apron. There is a pin that indicates the correct level but the oil cup is set at a height that provides oil level. Just put oil into the cup until it nearly overflows. The oiling points (including down t...

Re: Phase Converter Help For Viceroy TDS 1/1 GBL

Hello 3 terminals means the motor is fixed 400VAC. 6 terminals means the motor will run 240VAC or 400VAC. With VFD, motor power peaks at the rated 50/60Hz. This has nothing to do with the VFD. It is because of the physics of motor design. For this reason, it is usual to fit a larger motor that provi...

Re: Viceroy TDS6 Drive Belt

Hello I would recommend you simply use the VFD run down option as an emergency stop. The aim is to stop the spindle rotating as quickly as possible and that is achieved with power on the VFD. There are technical reasons to avoid cutting power to the VFD supply. Under certain circumstances, it can da...

Re: Viceroy TDS6 Drive Belt

Hihere The poly link style belt is a good choice for a lathe. They are good at absorbing shock and vibration. I have fitted a VFD to my Denford lathe and I am fitting a 4kW unit to a larger lathe. On a small lathe with a 1.5kW VFD, you probably don't need a braking resister. I don't have a braking r...

Re: Before I go and damage the spindle/spindle bearings

Hi
I actually ended up with quite a lot of pre-load.
On the left hand end of the spindle are two nuts.
These are left hand threaded..
Just tighten the nuts until you get the desired pre-load.

Re: Easiturn 3 Tripping House RCD

Hello

RCDs should be tested every 6 months by manually tripping them.
Best to do at daylight saving when all the clocks need to be reset anyway.

Testing RCDs improves their reliability.

Filters can cause RCDs to trip if they have large capacitors/inductors.

Re: Easiturn 3 Tripping House RCD

Hi The RCD is probably tripping because of all the power capacitors in the mill control system. Filling the capacitors with electrons looks like leakage fault to the RCD. Try connecting a 100W incandescent light in series with the mill. If there is no fault the lamp will be dull, and the control sys...
