Sharpening jig blocks

[21William]

I find it much easier to use jigs for sharpening so I made these blocks for some recent tools. The rectangular block is for my 10mm round skew, the large triangular block is for my 1/2" point tool and the smaller one for a 1/4" detail tool.

M6 set screws hold the tools in place whilst sharpening.

There are no pictures William.

Strange, I can see it fine. It is hosted on PB. Can anyone else see/not see the picture?

 

[Phil Dart]

Your picture is showing just fine William.

John,, just double check you are logged in.. If you're viewing as a guest, you can't see any images at all.

 

[Penpal]

Intriguing how does that work for you mate?

Brilliant idea William.

 

[Penpal]

For me there is one clear picture of three versions one on each tool, just how do you apply these in the process?

Peter.

 

[21William]

All tools are firmly held in place in the blocks with a set screw. For the skew chisel you place the block on the grinding table and grind the first face then flip the block 180° to grind the second face. Same idea with the triangular blocks, just grind each face in turn with the flat of the block on the grinding table. After I made these I did do a search on YouTube and found a couple of folks that hot glue the tool inside a couple of hex nuts to do the same kind of thing.

Wow comprehension followed thankyou. I have a triangular tool now I can sharpen it for the first time with confidence.

Yes, trying to get three equal sides can be a challenge without a jig. I've sort of managed it but a jig makes it so much quicker and easier.

Very informative I like your metal jigs did you use a milling machine to make these?

 

[wm460]

Once I get my mill back together I will make some of these.

 

[21William]

Yes, made on my milling machine. The triangular blocks were made using a spin indexer.

The triangular blocks were made using a spin indexer.

I need one of them.

 

[21William]

I need one of them.

They do come in handy!

 

[Penpal]

My visions of all the need toos means priorities have to be made but this appeals to me as a great way to go. Thanks.

Peter.

Unfortunately they don't make them for ER40 collets.

 

[21William]

No, I've not seen one for ER40. Mines designed to take 5C collets but came with an adaptor to take ER32 collets.

You could use a ER40 hex block though for making the triangular guide:

I like this idea. It works well.
