What are you machining?

[Seadog]

Just the bed levelling to adjust as it cuts a bit of a taper.

Is it bed levelling or the tail stock offset?

Very tidy looking thread

It came out perfectly, en16 is a lovely material.

Like you I don't mess about with the compound, straight in.

Bed. To be honest I never perfected it so it's about time.

Got an edge tailstock alignment bar for the tailstock.

I need to get a decent machinist level and set mine down.

One for sale here, strong money but if it's calibrated that's a big bonus because they are a pain to set up. Nice level though, same as one of mine.

To be honest you don't need it, a good quality builders level will get you close enough to adjust using the two collar method.

A builder's level bubble is unlikely to even move when a sensitive level will go full swing. Not the same thing at all.

My Bosch digital level measures to 0.1 degree but I think it’s still only 0.5mm a meter.

Whoosh.

If you use the two collar method you don't need a level at all...

Quite, 6 minutes of arc. My engineer's level is 10 seconds I think, 36 times more sensitive. Might even be 5 seconds.

Well, why even mention using a builder's level? By the way a 2-collar method is fine if the head is aligned by the vee ways. Not much cop for something like a Colchester that has an adjustable headstock.

For a bit of funsies old chap, we need to get our kicks somehow in lockdown.

I think I'm funny...

Brad won't have an issue, his headstock is on vees. Interesting though, how would one align the headstock?

One of my wives friends had been trying to level the washing machine with a Starrett engineer's level and been driven mad.

I bought her a level from screwfix and nabbed the starrett.

You gotta take the twist out of the bed first, then align the headstock with the jacking screws using the 2-collar test or a test bar in the spindle. The more wear you have, the more you're going to have to work at it.

Here's the Colchester test sheet.

Warco did not supply a circlip for the tumbler gear on my lathe. They did say they would send one out with a spare fuse, never arrived.

So gets a superglued retaining ring instead. I want to try cutting a LH thread, so need it reversed.

 

[Kram]

My attempt at a long screw, 240mm long LH thread 14x2TR

0.8mm deep, few more passes to go.

 

[Kram]

Helps if you put the correct insert in the tool! That was a 1.5ISO. Should be ok but needs realigning, which I can do easiest by loosning collet and moving the work. Its about 1.5mm out.

 

[Kram]

Done.

(Volume low I used air duster!)

 

[Kram]

Cleaned. Chip tray has not been this empty for years

 

[dobbslc]

What are the Warco lathes like?
You seem to do really nice work on your one.
Better that a Chester lathe?

 

[Morris]

Currently machining a front clutch piston for a Torqueflite 904 due to being a tad clumsy with the original. Can't find a second hand one and new ones seem extinct.
Roughing out at the moment, doing a bit now and then between other stuff.

 

[Kram]

It fits my shed and accurate enough. Without the motor upgrade it was rubbish, but apart from that I think chinese 10" lathes all about the same. A good used Harrison would be better, this only makes sence with limited space.

Anyway the 14TR2 thread not perfect. I did not bottom out the insert as I thought I was past full depth, so I think it needs to go back in for another cut. The split nut is tight (on and off) normal way round. If I put it on split end first it is free spinning
Marker pen rubs off the root.

Is that the left hand thread you did with the right hand insert?
