Mike I seem to recall JasonB has a little used one of those to dispose of  :-X

Not ready to get rid of yet and it is the standard length table, long table is a bit much overhang for all but light work. Though it would make a bit more room for the new CNC.

Splash out on a SX3.5 DZP they make sparks fly :)

Cheers, Jo and Dave,            I do appreciate your offer. It's a pity about the Atlantic :shrug:   For the present I shall pursue plan c and modify the RH nut.     Terry   Thanks again

Fair enough   but the offer stands.   Keep it warm on the back burner... :cheers:

I thought you were in Lancashire = UK is there another one  :o


JB welcome to the world of having multiple machines to choose from :-X Next you need a couple more lathes, but a DRO on the one you have would be a good start   ;)

Hi Jo,   I am in Lancashire but Dave steamer is in the USA
I have made a little progress, the short screw is now complete apart from handle keyways.   (need to buy a woodruff cutter)
At first the nut would only engage about one turn so took another minimum cut...just polishing in reality......nut engages easily. I thought I'd cocked it up :'(   However I set up my DI and tested axial movement and could only get just under 2 thou.  I know it will bed in but it has to be better than before.   Next move is a new square thread insert for the RH screw nut.
I must admit I may still buy the Sieg....... :thinking:

Thanks All for your interest and support.         Terry

More progress,   sort of ;)  need to cut the keyway    no mill, not even a vertical slide!  However I clamped the leadscrew onto the small lathe toolpost, put a 3/32" endmill in the 3 jaw.....one keyway :whoohoo:
Next move was to bore out the acme insert and make a new one with a square thread. Feelers give the gap at 0.062" and the thread width is also 0.062"  Later I shall grind a new tool for the job.  Good news is that the assembled short leadscrew assembly is perfect :cartwheel: I expected an improvement but not to this degree            Chuffed!!

.On the last lap now. I've cut the RH square thread in the nut after making a replacement insert. I have to admit to finding this bit stressful. I do not have an accurate means of checking the thread during the process. All I could do was rely on the accuracy of my toolbit grind and the backlash equipped cross slide dial. Eventually I got the leadscrew to start but go tight. Not able to decide if the problem was thread width or depth I tried engineers blue. After considerable tickling I chickened out of further cuts and settled for a small bit of stiffness. (it will bed in :shrug:) Nearly re-assembled it looks as though the old Raglan is good for more swarf making so that is the end of this thread.  I have appreciated all your inputs, thanks for looking in :ThumbsUp:       Terry

PS.. laptop playing up so will post photos asap :headscratch:

Hi Kerrin,        Not likely!    Just a small slide valve mill engine,             Cheers             Terry
