Re: Looking to build a dividing head

I do believe one of Dave Gingery's "Build a workshop from scrap" series included a book on dividing heads. He laid out and drilled the plates by hand on a drill press.

Re: Working with small wood pieces/patternmaking

I have banned wood on all my metal machines :D Filthy 'orrible dusty stuff. Valve core print? So you need a negative (mould) to make a core? If you mean valve as in automotive cylinder type, I'd make a reamer, probably out of an old valve. Hog out the block with drills, then ream to size and shape. ...

Re: Newbie - Buying first metal lathe

As to the insert tooling, they like to be run hard and faster than you may be comfortable with, starting out. Some shapes can be fussy with lead/clearance angles.
Very generally i'd say it's easier to get a good finish with HSS.

Re: Newbie - Buying first metal lathe

I'd warrant that most people are glad to offer help, and if you do ask something that's been well covered, or too basic, you'll get told to RTFM! Lathes have been around for hundreds of years, going back to treadle lathes driven by a rope wrapped around the spindle and to a sprung tree branch. Tis a...

Re: casting in the third world

I do a bit of casting. Usually in shorts, crocs, no gloves (Cast Iron I use gloves cos it's really freakin hot and my tongs are too short) The body has it's own very good pre-warning systems. IE you know when you're too close to something hot because it gets uncomfortable, so you move away. If you d...

Re: Enlarging Taper in Tailstock Quill--Pros? Cons?

"Don't make what you can buy" - Exactly the opposite of how I do things. Depends how you value your time I guess. I'd rather be making the things I need, than making the tools to make the jigs to make the machines to make the things I need. I've done enough machining (trade engineer) that it isn't ...

Re: Enlarging Taper in Tailstock Quill--Pros? Cons?

"Don't make what you can buy" - as earlgo said, if you can source the part that's your first solution.

If you can't then making a whole new quill would be my choice.

If you do decide to modify it, I would look for/make a piloted reamer to avoid the potential yaw issue Harry mentions.

Re: Newbie - Buying first metal lathe

I'm not at all knocking HSS. I run it almost exclusively on four of my lathes. Learning to sharpen it properly is a foundation skill as far as I'm concerned. I can free hand it, though I was taught by a very old, very grumpy and very frugal scostman. If you need a guide or rest, no drama at all, the...
