Thank for your assistance, I have download the book.

The gun is the RBL 7 inch 110 pounder screw breach loader in service from 1861 until around 1900, weight was 83cwt, HMS Warrior in Portsmouth Harbour has at least 2 of the guns on show.

Chers.

My son has just started making one of these 7INCH Gguns. He is short of some details. Do you have any Breach block details please or is yours a muzzle loader.

A belated thanks to everyone who contributed to this thread. I have actually sold the F3, it was good machine but I ended up needing a much larger machine so I sold it on.

I all ready run a toothed belt drive on a BT30 vertical milling head which I have designed, It used a 25mm wide belt, runs quiet as a mouse using a 1.1kw motor.

After reading all of your suggestions and comments I have decided to stick with my 1hp motor and try out a toothed belt and have a look at a polly Vee as well , although my large lathe runs on a polly vee at the moment but am not that impressed with it.

I thank you all for your comments and suggestion and will see what sort of success I have.

I want to be able to change speeds without stopping it.

I am still going to use the 2 step pulley on a V belt from the motor to the countershaft, By using a 1.1 kw motor will give me a better torque range than a 1hp motor which I currently have fitted, I am not making large components as I have a much larger lathe. I am working on a project which requires a large number of non ferrous components,I have a virtually new Myford capstan attachment and a multiple tool holding cut off slide. Some of the components need threading so need to be able to change speed, I used to be a tool maker and often tooled up medium to very large turret and capstan lathes.. I just wanted 1 toothed belt pully with a mod on it so that if needed I can still use the back gearing.

I am thinking of converting one of my Myford Super 7scto a toothed belt drive from the countershaft to the spindle, The plan is to power it with a 1.1kw 2 pole motor on a VFD, normal Vee belt from motor then a 1 to 1 ratio toothed belt to the spindle, reason for a 1.1kw motor is to compensate for loss of power I get from using a .750 watt motor at low speeds.

Any recommends or advice would be appreciated as am filling in my time as am self isolating.

Thank you both, the info and links are most useful, I am hoping to get the milling machine later this we or early next week.

Looks like I will be taking possession of an Aciera F3 milling machine.It uses W20 collets, my question is does anyone know the external dimensions of the collets or does anyone know where I can get a drawing, reason I ask is that I want to make short arbors to mount my tipped face mills on. Also anyone know of a W20 collet supplier or is it just look on ebay.

Thank you both for your comments, they have given me food for thought.

No doubt this subject has come up before.I have acquired an unused Myford turret for mounting on the cross slide, what is the recommended hole size for the tools and what is the hole size, depth and offset for the clamping bolts. Also is it best to wind the cross slide in as far as it will go to mount the turret . Any help would be most welcome

Just an update, we have tried the needles and they work, however it is back to the drawing board as although the car actually runs it needs some choke so running a bit lean, I am now making some more needles with a different and slimmer taper, am trying to steps every 1/8th inch so will see if I can manage it on my Clarkson tool grinder.

To everyone who commented thank you, I have managed to make these needles, I ended up removing the complete milling head from a small Clarkes milling machine I bought years ago from machine mart, I mounted it on my tool and cutter grinder, I then put the nickle silver rod in an ER32 collet and spun it at 2000 rpm against a 6 inch cup wheel, it worked a treat. I have just to put the circlip grove in them and we will try them out later this week, I will give an update about when they are intalled.

Jason , am going by the measurement I have been given by John, the guy that wants them. Thaiguzzi, I think John may have spoken to Amal as I told him they still make carbs, if he has not spoken to them I will tell him. I must admit that I want to have a go at making them, some of the things I have already made for John are bonnet mounted pennant holders for two of the Queens cars in her collection, recently I made a worm and wheel for a windscreen wiper gearbox on a 1938 Vanden Plas bodied Bentley and reconditioned a 1927 Rolls crankshaft vibration damper which had been stood for nearley 60 years. I do like a bit of a challenge, I have found out that the numbering on the drawings for the needle seems to relate to the fuel mixture rate at different throttle openings rather that different or variating tapers. I do however like to find or aquire advice from people, The response I have had with helpful comments, ideas and advice from my request is really appreciated.
