The stick out of the cutter is causing a lot of chatter. Also, the stack of washers will never do. Make a larger tool holder out of solid steel. Next, to keep the cutting tool closer to the face plate make the compound parallel with the cross slide. I appreciate your effort to improve your lathe. Cheerio
I'd be careful drilling out the centre. Drills will always make a hole slightly larger than their intended size. Might need a reamer to get it spot on. Then again might get away with it.
The bore in the first faceplate was too tight to slide onto the spindle, so I had to drill it out anyway, and even after that it was still pretty tight!
I have no idea why folks like to leave the top slide at 45 degrees. Put it at 90 degrees either way and you should be able to reduce your tool overhang heaps.
The two toolpost locations are on front left and right corners of the top slide, so angling at 45 degrees actually gets that corner closer to the workpiece for me.
The centre mandrel will be a lot easier to extract if you turn a low draft taper onto it. Much easier to knock out if it isn't parallel.
Turning a taper on it would be very easy if I had a working lathe to do it with! ;) lol
new subscriber here, thank you so much Alan.......best wishes from Florida in the US.....Paul
well, you know the casting is solid anyway.........cheers, PB

Cool, keep going!! Greetings From Brazil

The persuader, love it
Commenting before watching. Wondering if the title “First Faceplate” is ominous foreshadowing.
Yup. Ominous foreshadowing. Sorry about your luck. Glad you kept at it.
Plan B sound good !
Could it be that the faceplate is not mounted very solidly on the spindle and shifts a little bit while machining?
No, I didn't do a good enough job of keeping the mandrel at 90 degrees while casting.
7:40 , holy smokes......shorten up the stick out on that tool.......
the vibrations you are getting must be tremendous......
How NOT to do it. Can be almost as useful as "How to do it"!
