Hi Everyone

I am repairing a very early English made cast iron fuel tank , age approximately 1910. .

The drain plug is is a brass/ bronze stopper. The problem is I cant identify the thread type/ size.

The stopper plug is 0.424 inches diameter x 25 TPI.

My thread gauge identifies it as 25G

Can anyone identify this please

many thank ray

Hi martin thank you , can you direct me to that link please? ray

HI i am contemplating buying another DRO for my mill.

Short of buying a very expensive unit such as a Newlall or similar, there are currently numerous china made DRO units on Ebay for less than £75.

I currently have a number of magnetic reader heads all with the standard 9 pin plug. Assuming I purchased a china made unit , or any other unit with a 9 pin fitting. , what are the chances of my magntic reader heads working with a strange main unit? do they all use a similar language to comminicate.?. This question is assuming the box I may buy has the same 9 pin plug as my readr heads. thank you

HI,

I am wondering what make of tool boxes you all use.

I have Britool multi drawer boxes which are excellent and also a number Wolf multi drawer Boxes. The Wolf ones are very close to the Britool quality... Short of paying SNAP on prices, which make of boxes do you all use. For several months I have tried in vain to buy more WOLF boxes, but they have totally disappeared .!!! Appreciatte your thoughts on various makes and their quality of construction. thank you

Hi Duncan ,

thank you will check my manual again .

Agree we are talking feed shaft only

.kind regards ray

HI ,

Can anyone advise me please

On the Myford 254 lathe (any variant) Feed shaft from the multi speed gearbox to the saddle / apron.. When using Power feed or cross feed, as a safety measure, is the drive protected by a shear pin or adjustable slip type clutch?

On some Lathes such as the Myford 280, there is a user adjustable slip clutch built into the saddle. so it acts as a safety measure , or if you are using a bed stop will trip out when the saddle reaches the bed stop..

I have checked the manual and can't find a reference to it.

Appreciate the advice , thank hyou

Hi yes 90 to 1 ratio. IE 1 turn of crank equals 4 degrees. Thank you ray

Hi , I Need to cut a gear with 13 teeth. I have available a Vertex H/V rotary table.

13 teeth work out at every 27.692 degrees. Any advice or suggestions on the

best plate to use please , many thanks ray

Hi I am working on a project and need a rack and pinion.

I have discovered that the bed rack on my Myford 254 appears to be 6 TPI and only a small cross section of approximately 0.3 inches wide and 0. 625 inches deep.

This would be an ideal size for my project.

Enclosed is a photo of a similar rack off a Myford super 7.

Can anyone suggest a supplier for one of these racks please, or indeed one off a Myford 254, or anyone breaking a 254.

Thank you

Hi Apologies for the delay.

I Have now added photos of the Motor spec plate and wire instructions. It appears the Motor was factory pre wired 240 volts, but as per wire plan can easily be wired for 440 volts. Thank you ray

The motor has 9 wires. ( see plan sketch ) Cables are named

U1, U2, U5,, V1, V2 , V5

and W1, W2 , W5.

I have a standard 3 phase , 3 cable / live supply I.E. No neutral.

any suggestions on which wires should be joined

and which should be connected to the live feed inputs please

HI

I have just purchased a RF 31 BENCH MILL.

It is made by RONG FU Taiwan.

It is new, unused but "shop soiled"

I need a few additional parts for it.

It is well made, robust and heavy weight is 600lbs +

I have contacted the original supplier in USA, - -his name plate is on the machine.

He says he has no european contacts and cannot help..

Does anyone know of an agent or supplier in UK or Europe

I appreciate all advice thank you

HI CHAPS

I have 2 sets of DRO with magnetic pickup from EMS which I fitted 5 years ago. One is 3 axis fitted to a mill and the other to a lathe. the magnetic strips are VERY easy to cut to length. I even fitted a bit of magnetic tape onto the down spindle sleeve on the mill. They are very resistant swarf and coolant . They have worked faultlessly on every occasion. I have just ordered a third unit for another lathe. Good product, good service, very helpful and extremely knowledgable. EMS Without doubt.
