Could it be a difference in voltage between the UK and Germany? :lol: :lol:
Or perhaps the lathe used, maybe the size of the operators cahoonies? :scratch:

I couldn't stop my lathe in that little slot even if it were running at half the speed... the problem I've got is the clutch doesn't work too well at the slower speeds, and the brake doesn't work very well at the higher speeds... and the whole thing has so much momentum it won't be rushed...
Bernd:
Found his web site here: http://shop.rb-werkzeuge.de/
About halfway down he has a pic of the tool. Interesting how something so simple has turned into such a complicated tool that I see now being used. Looks typical of engineers. Take something simple and design it into a complicated tool and sell it for hundreds more. :lol: :lol: But he's selling it for only €99.
Going to have to try and, or should I say, I'm going to build one just to see what all the flap is about. Glad I'm only a model shop and not a model production shop. :ddb:

Can't understand what all the fuss is about and why people are getting so heated?
It's a tool, it cuts single point threads simply and easily unlike any tool before it. Many people have made their own versions, nothing complicated needed so even absolute beginners can make one successfully. Only have to see John Stevensons under engineered stab at it to appreciate the simplicity required.
Everyone's attempt to date does the job so big clap all round me thinks :clap:
They are simple and they work flawlessly, what more do you want?
Nice to see different peoples take on the idea so keep them coming :thumbup:
John Stevenson:
He's also pinched my edge finder with the bearing :doh:
Anyway for those that haven't seen the tool I did that was on the HSM site here it is.
This is it in it's final version, the original tool was just a hole reamed thru a large brazed parting tool reground into a threading tool, with a slot cut in the bottom. The bottom keyed plate is machined from solid and bolted on to make fitting easier than try to mate up slots and side play on the pivot.
The whole original toolpost with the red tool literally took under an hour but I had got the tool holder blank.
Link to youtube to show it working.

Because I have also used the die pieces out of Coventry Dieheads for a long whole I then wondered if they would work on this tool so the second holder was made. Basically it mimics the red tool and just holds a die piece.
For a test i took a piece of 16mm rebar reinforcing rod, probably the worst material know to man, beast and next doors cat.
Set up in the lathe and went for it, vid here.

And a close up of the thread here.
Some tearing but given the material it got to be the best thread I have done on this crap. I use this tool to thread everything now and I do a lot of threading running a repair jobbing shop.
