Pleased to see you have seen the light, good decision if you have any doubts, some pictures will certainly assist in providing reasons for the failure.

More info re make and type of starter and motor would help to give some advice, pictures speak a thousand words.

I can imagine using a 1mm wide parting/grooving tool on small diameter rod and tube, no need for extra width if all is set up correctly. Recently did some grooving for cylinder fins in EN16T, tool is ground HSS and .60mm width, fin depth is 2mm.

Change your feedrate to something around .004" per rev, looks like your feed is on thread cutting rate.

The bolts will probably be too long to use with the heads recessed if they are intended to be used in the outside slots.

Only when powered up, the Z axis will need some kind of brake to prevent the head dropping with power removed.

+1 for Emco and Denford cnc machines, I regularly use an Emco F1 cnc mill, a Compact 5 cnc lathe and a Denford Orac cnc lathe which is a bit bigger than the Emco 5.

All are simple to use and can be converted to modern control systems with minimum outlay, they already have adjustable ball screws fitted to both axis, 3 axis on the F1 mill.

I currently have 2 Emco Compact 5 cnc lathes ready for conversion for anyone interested.

I was told by the machine supplier of my Herbert 0V the taper was an R0

H7 will provide clearance within certain limits, check online for details of engineering fits for shafts and bored holes.

Measure the PCD of the 36 hole circle and the chordal distance between hole centres, the dimensions obtained will allow you to calculate the exact hole position for the additional hole, make a jig to use when drilling the additional holes.

Like John I also use an Erikson Tenthset boring head, adjustment is .002mm on diameter per division, allows very accurate boring to size. This is a No.12 and uses 12mm diameter tooling shanks

Download the manual from this group, joining is FOC

Drilling deep holes in any kind of masonry requires an drill with unworn tips, otherwise when the hole becomes deeper the less worn drill flutes are bigger in diameter than the front section of the drill, result is the drill stalls in the hole.

I would think heating to silver solder the 2 pieces of EN8 would change the properties of both pieces and possibly cause a weakness in the spindle.

Best no doubt to get the job outsourced if you can't bring the lathe up to standard, turning between centres may help to get both ends parallel for the distance required.

I had the same model many years ago, my first milling machine, and one thing I remember is having to remove a taper pin from the leadscrew for some reason, possibly to remove the screw from the table.

Hi Bernard

Is that the fwd/rev switch operated by an apron lever ?

Looks like Wiki has it wrong on this topic, not the first error on that platform. !!!!!!

Hi Peter

What are considered "out takes" please ?

Emgee

Green grit wheel for grinding carbide, or you can use a diamond impregnated wheel for a good finish.

Thanks to all who responded, some very useful information taken on board before making any more videos, some of the points I have always followed but some hadn't been considered.
