Thread: Spindle rouging gouge, Woodcut jig thingy

Here is the U flute profile on that P&N SRG...

With the same leg setting you used I got this...

So, a straight across grind can be achieved. I also eased back the top of the wing just a bit to reduce the chance of a catch on those top edge tips.

I positioned the slide back to the 100mm mark to give a 45° bevel, but that will depend on where you have the bracket for the slide screwed down in relation to the centreline of your grinder. From memory, I think the back of the bracket is level with the centre on mine.

Not that I'm suggesting you grind your SRG with the jig. Much quicker and easier to do a straight across or very slightly swept back grind on the tips with the platform. But, if you were ever wanting to tidy up the bevel a bit it is an option.

Don't hesitate to get back if and when you move onto using your jig for bowl and spindle gouges. I'm sure there will be plenty of advice on offer!

Neil,
It’s been quite a long year an quite busy,as it only just hit me like a freight train going sideways, that these numbers are actually metric,
An when fine people like yourself say I set the slide back a 100 mm , I now COMPLETELY UNDERSTAND WHAT YOU MEAN, I will have another play after the Great Big Marketing day is done an dusted an we can all look forward to Hot cross buns on the super market shelf’s.



Cheers Matt

I've not got around to my workshop since then so I checked the online manual for the Tru-Grind and it has the following...

Tru-Grind jig setup.jpg

"For 6”(150mm) wheels align the rear edge of the Tru-Grind base plate with the centre line of the grinder. For 8” (200mm) grinders bring the base plate forward to about ¾” (20mm) from the centre line of the grinder"

The height of the spindle is also important.... "Height from the bench to the centre of wheel should be 150 -160mm (6-6½”) for both 150mm(6”) and 200mm (8”) grinders."

The other variable is the position of the depth block for setting gouge protrusion from the jig, which is given as... "50mm (2”) back from the edge of the base board or bench".

Of course, you can position your slide wherever you want, but then the numbers on the slide and leg angles will be meaningless from others unless you have the slide fixed in the same position and you are using the same gouge protrusion.
