Hi Everyone
I am Grant, I love to fettle and tinker with stuff so decided its time to fit the old garage with a "real mans machine" and bought myself a Warco WM250V Lathe.
Being new to the hobby, I discovered that for the money these lathes are ideal for the garage hobby fettler provided you spend a little time setting it all up.
I plan to gain a wealth of knowledge off you good people here so hope you all don't mind if I bombard you with a million questions.
Anyway once my lathe was on the bench, the next order of the day was getting it level, well, as close as my bench and setup would allow anyway. Armed with a precision spirit level I proceeded with some shimming.
Shimming at the headstock end:
Shimming at the tailstock end:
Levelling all done and it was time to give it all a good once over. Removed and cleaned chuck, removed and cleaned gears, aligned tailstock to centres etc….
Did some more research, watched some YouTube videos and learnt HSS is the way forward so on to grinding my own Facing Off Tool:
and Turning Tool:
I ripped a shaft from a old scanner I had laying around as I have read that they are hardened and machined to precision so used this to check the runout. I used a 0.001mm digital gauge for this job. As you can see in the next picture, it was rather difficult getting the digital gauge to 0.000 so I decided that 0.100 would be my new 0 for the test:
The value climbed to a maximum of 0.044mm 190mm down the rod and then started dropping back down towards 0. My bench does have a little bow in it so I am guessing the ways are following this profile. I also considered that the rod may also be flexing towards its end as its unsupported. I thought about drilling a centre hole and supporting the tool/rod with the tailstock but was unsure if this is defeating the whole purpose of the test???? Perhaps you could advise on this matter.
Checked the runout on the horizontal plane. Difference from chuck to end of tool/rod 320mm = 0.220mm.
Made the girl a little apron to catch the chips and offer the ways a little protection:
to be continued…..
