EN1a should be fine.
I've now got front and rear QCTP.

How far away from the chuck are you parting off? It looks to be quite away?

Thread: Quick change toolpost
13/10/2018 15:31:43

I use a "222" on my Chester Crusader (Ø300mm swing) and a "000" on my Sieg SC4. Both are perfect size.

I could have possibly got away with a "111" on the big lathe, but most of my tools are 16mm shank.

Going over to a wedge QCTP has transformed the tool holding.

Just be aware that tip quality can vary, last time I bought a "bargain" holder and 10 tips the tips were pants, ended up getting some decent tips that cost many times more but they made an unusable tool usable.

Very good point Jason!

I had some from Ebay a few weeks ago, total rubbish, clearly reject items!!

**LINK** are my choice for inserts usually.

Thread: Rocol RTD shelf life
30/09/2018 09:16:39

I've just read the data sheet for it...

That said, RTD liquid is the best I've found for stainless threading. I do now use an extractor fan though, as the fumes are bit bad.....

Thread: Extra axis on lathe?

I'm very pleased with progress so far. I'm powering the spindle with a Makita battery drill for now. Its working very well!

Just need to sort out a spindle brake and indexing ring for the back of the spindle next.

Nice idea.

I had thought of trying that on my Crusader, but .015" size difference put paid to that one....

At work, we've had a fair few over the years.
