Microscope adapter

Hi I purchased a Bausch & Lomb Stereo Zoom 4 microscope from ebay USA. This is for electronics, which use parts small enough to require a microscope to work with. To reduce shipping cost, I found a microscope with a mount but no stand. The plan was to buy a computer monitor stand and make an adapter...

Re: Countershaft drive belt tension.

Hi
Each end of the pulley shaft is machined like a two pronged fork.
These fit around the adjustment screw in the slot.
If one slot is higher than the other, the shaft will jamb.
It is as simple as that.

Re: Countershaft drive belt tension.

Hi If your belt is of the type that is made up of linked segments, then these belts stretch a lot. That is one of their features. I suggest you start by removing the belt and degreasing it and the pulleys. I oil my gears with spray-on chain lube. It goes on runny but the solvent evaporates to leave ...

Re: VBiceroy 1.1 TDS GB Pulley size for vfd conversion

Hi The major reason I replace the step pulley with a single pulley was because I always had problems with the motor pulley working loose. The easiest way to solve that problem was to fit a single pulley. With the back gear, that gives 2 gear ranges. That is enough for high torque, low speed operatio...

Re: Model Engineer Workshop : Cross slide copier

Hi Attached are some photos that show a cross slide copier attachment. This is designed to copy the profile of a template onto the end of a bar. This is something that cannot be done with the factory copy attachment. I have used parts of the factory copier to make the cross slide version, but nothin...

Re: Denford Viceroy TDS VSD conversion

Hi Five years after a post that said I had been working on my next VFD conversion, a Brazilian made Nardini lathe, here is the result. It isn't a Viceroy lathe but I used the Viceroy to make parts for the conversion. This included pulleys for the poly-vee belt conversion. I replaced the entire elect...

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

Hi
The extra cross slide is just a copy of the factory one but with Tee slots. It is a lot like a Myford version but scaled up. Nothing special.
I have never had it mounted on the lathe. Never needed to use it.

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.

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.

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.
