What are you machining?

[Kram]

Yes I did diamond file just incase it needed more side clearance but the thing is so small it was hard to tell. Seemed to cut ok

To get the perfect thread you would probably need a negative shim.

Here is the info from Sandviks threading pdf, it is well worth a read as it has a lot of good threading info.

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.

What’s a edge tailstock alignment bar?
I just turn a piece same diameter as tailstock barrel and clock across. Good way of measuring tailstock sled wear as well

 

[Kram]

Ground these two holders down so they wont hit the tailstock center next time. There was contact when threading but not enough to knock the center out. While I was at it I reground this carbide boring bar. The old tip too small to grind so ground it back to the shaft.

It's just a bar with centres and a ground diameter on each end.

Well I usually set it with the first clean cut on the job after I last moved it. Unless of course I need to centre drill something.

How much!?! I'm pretty sure I've seen DoubleBoost do it with a length of 10mm stud with big washers on each end.

Think I paid £30, it was in the early days of my lthing when I didn't know any better.

Why is it every motor and pully ive swapped has needed a 1mm or less bush/shim.




Only when i put the two together did i discover that the pully is bent. Explains why the old motor shaft had hammer blow on it.

Important job on this morning - we picked up a globe light for my daughter that someone was throwing away and it was missing a plastic bushing.

Only one thing to do.... unfortunately I only had steel bar in that kind of diameter so the bush weighs about as much as the rest of the lamp combined, but at least it’s now usable and spins.

Made four of these stainless adaptor thingies...



To hold some of these...



To go in here..



To look like this.... bath done as well. Made as I couldn't find the correct size, and was sent these wrong ones by the tap manufacturers, Ideal Standard!

Very smart, excellent work.

What stock did you use? I haven’t got my mill working so can make a hex.

Is your lathe in imperial?

You haven’t put a 9/16 hole through them then?

 

[grim_d]

@Brad93

Just round bar I had, screws are EN1A and nuts are EN8M.

You can do a hex in the lathe but it is a bit of a rigmarole. I'd be happy to put a hex on something for you if needed but I'm quite sure there will be someone local to you willing to help.

Or just drill a hole to put a bar through?

My lathe is a weird hybrid, everything is metric apart from the leadscrew, all the fasteners are still imperial though (just like my mill)

What's the 9/16 hole for? The base of my lathe has threaded holes for the levelling screws.

On my lathe the levelling screws have 9/16 holes to bolt it down once levelled.

So how do you thread imperial? Still have to use 63t or 127t change wheel?

 

[grim_d]

@Brad93, to bolt it to the ground?

The manual for the L5A wants it to be levelled then the base to be mortared to the floor... It's not critical enough for me to go that far.

The screwcutting leadscrew is imperial so it cuts imperial straight "out of the box". I use a 127t and a 40t to cut metric with a 63t in there for the .75 pitches.

There's pictures of me making them a couple pages back.

wow did it come with a 127? That’s handy.

Grout rather than mortar most probably.

@Brad93

No, I made the 3 gears necessary, read the whole post.

Yes, grout not mortar.
