Hello all

Let me tell you how I adjust the position of the universal support in a quick & accurate way.

I've added a nut on the rear of the threated rod (see 2 attached pictures)

If I push the universal support against the front nut, I obtain the position equivalent to "Hole A" (Tormek TTS-100)
If I pull it stopped against the rear nut, I obtain the "Hole B" position.

No need to insert the TTS-100 Inside the rod of the universal support, no need to lean and look carefully the contacts with the grinding Wheel. And the position is still accurately the same .

(this method is convenient for me as I use a diamond Wheel (allways same diameter) and as I need only 2 positions of the support )

Hi
After experiments several settings for sharpening the roughing gauge with the SV186 tool, I finally prefer the following :
- JS 6
- hole B
- protrusion 55mm

The result is closer to TORMEK recommandations when using SVS-50  (alpha angle=35° and a positive rake angle)
It works very well and the SV186 is helpful for the repeatability

regards
JR

YES !
I use to refer to your SHARPENING HANDBOOK , very clear and very complete
thank you again for this work .

By the way may I suggest a topic to add to :
I've tried to use the new SVD186 for sharpening of my rough gauge
this is made possible by the larger opening for introduce the tool

The best settings I've found are
- hole A
- protrusion 75mm
- JS6

Have you experienced also ?
what are your settings ?

thank's again

Hi Rob

Thank you for your prompt answer.

I am certainly new to the forum, but I practice the sharpening of my woodturning tools since several years with TORMEK machines.
Considering this I can humbly pretend to master the TORMEK principles and settings, especially for the sharpening of bowl gouges with the SVD-186 jig.

You remind me of the 3 variables to be adjusted :
- "jig setting (0 to 6)"
- "hole A or hole B"
- "protrusion of the tool" (55 , 65 , 75 mm)
I know thoses settins well and practice them every day, thank you anyway for taking the trouble to remind me that.

Unneeded also to tout the benefits and high qualities of the TORMEK products, I'm convinced and very satisfied with their system.


But my questionning about the graph in the manual persists and I'm still in search of a satisfactory answer .

Let's consider a single row, by example the 4th :
- the tool protrusion is set to 65mm
- the jig setting is set to JS3
- the hole used is A
With thoses 3 variables settled in this way How then is it possible to obtain such several edge angles as 35° , 45°, 55° and 75° ?

It is in conflict with saying that the 3 adjustments are sufficient to determinate a profile and only one.

Thank you for taking the time to carefully consider my questioning ... with the manual in one hand and the SVD jig in the other hand 

Still waiting for a rational approach and explanation of this graph.

Hello all ,
as a newbie in the forum I first send my Hello to all

My question is about the graph in the chapter "bowl gouges" of the manual (page 20 in the English version 3.1 or page 82 in the french version - Cf attached pdf file))
This graph show the patterns of various shapes of bowl gouges sharpening in a table 4 columns and 7 raws.

Before launching this thread, I've tried to fond out the logic of this table but until now it remains impossible for me to understand ?

If you consider one same column (i.e. the first left column), how is it possible to obtain the same edge angle (35°) with varying 4 différents JS presets (JS0 to JS3), (knowing that the protrusion P is allways maintained to 65mm) ?

thanks for your explanations
