YEP - you've got it - I already checked and unfortunately hollow bar with 30mm I.D. and sufficient material for my spindle nose O.D. (58mm) isn't available - so its a piece of solid bar for my lathe...

This lot will catch someone's eye...

Looking at many of these posts including Michael G. with the youtube video where he cut the back plate threads to finish that one off has got me thinking.

For lathes with screw thread spindle...

Obvious downside - hurdle that I encountered was finding backplates with the spindle nose thread available anywhere sensible, shipping costs from the US on ones I did locate were equivalent or more...

Check the condition of your spindle nose internal taper - very likely it will be pristine hopefully

Yeah cobbling together a mosaic of information from manuals of similar machines is the way to go - I have the manual for mine, to say it's light on is an understatement...



Have a look at the...

MT4 potentially means that you could get an ER32 or ER40 -> MT4 adaptor and have it go straight into the spindle nose taper for a collet chuck.

Is yours the 12"x36"?

I like the belt drive,...

MT4.5 is actually good given that the bore through the spindle on my machine is ~35.5mm, but unlike the full integer MT taper accessories there isn't off the shelf tools available unfortunately.

Check your spindle nose taper, mine's MT4.5 which is a PITA to find anything for, your machine looks very similar.

Till J&H explained how to make one - clever technique - I was wondering if there was a special niche breed of cattle, bred for unfortunate shaped lumps

You could probably achieve a result with a few flat leather washers - got any belts in the wardrobe you've grown out of, or a quick trip to the op shop?

I wouldn't normally have considered a step drill, except I was being cavalier due to the 'cheap' price of the $5 set and needing to enlarge the bore through a...

That really sounds like a job which is perfectly suited to a 16mm annular cutter in a mag drill?

Do you know anyone with a mag drill?

Thank you for this, I'd just watched a few youtube 'reviews', was partially convinced, then read this - I won't hold you liable as I know there may be some gotchas.

Fascinating gadget as a laser engraver, no actual experience with any engravers, however from numerous youtube videos, even on softer metal materials, vibration is the enemy.

Hi Baron - I had started to read that Brooks TCG thread a few days ago whilst researching something else, it's a long one bookmarked now for future reading
