Hello, my first post regarding my first lathe.. Managed eventually after many failed attempts at buying a lathe to get a Myford M Type Picked it up Sunday, chap even knocked the price down when I got there :-)
It came with a selection of gears, tools, chucks etc
Managed to get it installed and gave it all a good clean and it is bearing signs of many years neglect and abuse
The lead screw half nut mech is very vague and stripping the half nut of the lower has revealed that it is very worn and IIRC looked like it has tried to cross thread at some point I have joined the Drummond yahoo group and had a look in the files section where there is a set of diagrams for creating a bolt on half nut to the casting making subsequent replacement trivial
I am certainly in no hurry to get screw threading as I am a novice and realize that there is plenty to get my head round before I will require this feature (not used a lathe since school - which was many many years ago)
I have pondered as to whether it would be possible and easiest to remove the casting, clean up where the threads were and silver solder some material (maybe using tube) and have it re threaded and then mill the top half of the tube away leaving a fresh new half nut?
Can anyone see any problems attempting this?
The bit above the half nut, is this also supposed to be threaded or just a pad to support the pressure of the half nut when engaged? This "pad" bit is bolted through an vertically elongated hole in the carriage, I'm guessing to make it adjustable? does anyone have any info regarding how to set this up correctly? could it be that mine is just mal adjusted as the half nut does have threads , just thinner than the screw's and not square (gone pointy)
Also the tail stock is a morse taper, but which one? (M1 and M2 seem to be common sizes quoted for Myford parts on the bay of e) If I take the chuck off and try and fit the morse attachments I have into it they "seem" to fit but not as nicely as they do in the tail stock,though I didn't try and clean it out before trying so could be traces of swarf and hammerite that seems to have been liberally spilled everywhere, good job they didn't attempt to de grease before doing this as it seems to be coming off easy enough (are they supposed to have an internal morse taper here? again which sort should it be?)
Thanks in advance Apologies for the long first post and if I have used the wrong terminology, I am a newbie and enjoying the learning curve so far...and perhaps still a little too enthusiastic in finding out about this machine
