Scheppach Tiger/Tormek/et al alignment technique

[RogerS]

I was wondering what method folks used to ensure repeatability of the grind angle.

I'm particularly thinking about how to maintain the edge at 90 degrees and also ensuring that the radius of the cutting edge accurately mates up with that of the wheel.

IIRC the jig that holds my chisels & plane blades allows you to slide the blade up to one side which, in my naivity, I always assumed that was 90 degrees.

As to the radius of the cutting edge, I use the Tormek angle thingy and grind to that, I've never been too woried about whether the radius of the cutting edge matches the wheel.

Maybe I ain't understood your question correctly, that wouldn't be unusual for me

I am refering to small Tormek, never used anything else.

Likewise Losos, never had a problem.

Are you having a particular problem Roger ?

Cheers, Paul.

Scheppach have recently moved their manufacturing from Germany to China. The prices have dropped hugely, and so has the quality I fear. I bought the smaller machine about a month ago, and returned it after the weekend. So did others. Very little was square. Consider such machines as "kits", that is, they require a bit of work to make them reliable.

This machine is also re-badged as a Triton.

After returning mine I bought the Tormek 2006. A vaste (!) difference in quality and performance.

Roger,

I set my bar at 9mm above the surface of the stone with a scrap of plywood.

Then true the stone lightly with the diamond tool. It should now be parallel to the bar. I do not move the bar again............

Then just note the projections for each tool which give the approximate angle you wish.

The key to my method is keeping bar at a standard height and dressing after fixing bar height. Pleas note that I usually only use the Tormek as a grinder for plane blades and cabinetmaking chisels. No carving or turning done here.

Many thanks guys.

Losos - I noticed that there seems to be a stop on the jig but not having a square to check it......seems like a good starting point though.

Chisel - what started me thinking about this was that the grind I was getting was so clearly different from that done by the manufacturer.

Derek - Mine's the larger version and build quality is still very good (although I did initially have a slightly eccentric grid wheel which was resolved thanks to excellent service from NMA)

David - I like your approach and will give that a try.
