More stuff

Some more pics.

I have dug out the trial version of my taper turning attachment, this needs a couple more mods to it to finish it off, i.e. marking fiducal lines to define the taper being cut, a more positive return screw action 'n stuff like that. As always I have used old drill MT's where possible & being commercially produced are as accurate as can be.The ball nose (from old ball bearing) was silver soldered on to provide some lateral movement in non protected centers (methoughts  ) still have yet to prove it's practicality in  tests  .
 






Clamp type knurling tool, all the knurls in my pics were created using this






Will post some more later (hope some of you are not getting too bored)

Bored? No way. WE LOVE PICS

Thanks for posting
The taper turning centre looks to be a handy bit of kit

You make it look easy....

Dont quite understand the tailstock taper tool, but it looks neat and well used

You put the tool in the tailstock and mount your work so it's riding on the ball end, then you use the knurled adjuster to move the ball off-center. Now when you turn the piece you'll be forming a taper with the thin end nearest the chuck.

I don't see how degree markings are going to help however, unless you always turn a taper of the same length. If you off-set two different-length pieces the same amount (according to markings) you will get a different taper for each. Or is this something catered for by the reference to 'fiducal' lines?

That IS a neat idea though, and nicely made.

Thanks for the comments guys.
My concept of the 'fiducal' lines was to indicate settings for the more common tapers used i.e. 1,2,3, MT perhaps  'indicator lines' would be a better description (symantics?) I agree with your comment about different lengths producing different tapers but these lines would only indicate standardised 1,2,3, MT lengths  & I don't foresee myself doing anything other than common tapers  so a couple of lines set up from either side of center line would be a helpfull quick ref. If you want to create a 'spot on' taper you can always set up a master taper in the headstock & set your compound slide using a DTI, or if you are really clever you could use 'Trigonometry'  to calculate the offset, mind you I would simply use the taper charts from 'Zeus' if I needed to be that accurate 
Am looking at posting more pics this weekend so bfn
