I made this the other day after getting fed up pulling the chuck round by hand when cutting threads.  Inspired by something Tel posted about basing his on an anchor bolt - well that is a 16mm masonry anchor! and an m8 bolt is a nice sliding fit in 10mm od copper pipe in a bored out file handle. I call it my Tel handle - because it isn't pretty but it works well  Thanks for the inspiration mate ;D Andy |

A tip I was shown by that old maestro, Tom Bartlett of SMEE was to use a large handwheel instead of a cranked handle. If you should forget to remove it before starting the lathe, then you don't have a lethal device flailing round. I found one at a very reasonable price on a second-hand dealers stall at an exhibition. It has a tapped hole near the rim so that I can fit a handle if its absolutely necessary, but for most jobs its not.

Guys,
One could easily make a hand wheel out of plywood/MDF. Perhaps even build one up from layers and have a hand-friendly tyre.

The important thing to remember when using a mandrel handle of any kind is that if you are also using a carbide tip, NEVER let the chuck turn backwards. It will break the tip. Most annoying.

I'd fit the handle anyway - here's a tip from the old messtro from Oz - a bit of quick mental arithmetic, and counting the turns as the handle reaches the bottom of its 'circle' allows you to put a pretty precise length of thread on a rod, or in a hole, with die or tap. Not baggin' out your idea Ulster, just pointing out one of the benefits of the handle. |

No problem Tel. The tapped hole helps in the same way. Problem is, the telephone rings or I have a senior moment and all the good work is wasted. Any cure for advancing years? (Except for a 'trophy wife' that is!)
Regards, Geoff

The fluffy animals behind the lathe must be well house (workshop) trained!

Cheers Tel, its difficult but I manage. Sometimes I seem to spend more time cleaning and putting stuff away but as Russell points out I do have two well trained fluffy things behind the lathe that work well.

Paul Whilst waiting for a new starter switch a while ago I decided to give it a good clean and and a touch up with paint. I acquired it from work as a none runner and rebuilt it, now its my pride and joy.  |

G'day all.
I shared "Ulster's" concern about the flailing handle particularly as I like to drive the lathe back to the start. Before you ask. you can't use the threading dial when cutting inch threads with a metric lead screw. I do like the challenge of using the thread dial and engaging the half nuts at just the right time; reminds me of synchonising generator with only a set of lights or watching the synchroscope.
Last week I was in the hardware store and I purchased a wheel about 200mm diameter and a long expanding bolt. So it off to the lathe where I made up a spigot with an expanding collar. The design changed as it went along but the outcome works.
I'd post a picture but Ace's workshop shows me up.
Regards,
Ian
