Thread: Small Blade Sharpening Jig

Hi JM. Very clever jig. I have done this freehand but your bevels look much nicer.

Hi Mountain Ash


I was also looking at Linear Bearing Blocks that you could mount attachments to with the four mounting holes - possibly another 4mm Aluminium plate with 20 smaller magnets to hold flat knives and the like.

Cost for the block is $5.92.

Hi Jono

I used this method, utilising the Veritas small plane jig and a bench grinder with the Tormek BGM-100 guide, in 2010 ...

This was great for grinding the shoulders of chisels and made a great set of Stanley 750s ...




More recently I came up with a less complicated method for converting bench chisels for dovetailing ...

This involved a simple guide on a belt sander, which re-angled the sides ...



Good for dovetailing ...

Hi Derek,

I was searching the internet for information on dovetail chisels and did end up on your web site. I actually did not know about the Veritas jig and the Tormek rest until then... I could not find the Veritas jig for sale and the Tormek is around $100 I think.

CNC online shops sell all sorts of parts, brackets and 12mm rod - this led me to DIY my grinder set up - at low cost - my 12mm rod rest is not as easily adjusted as the Tormek with screw but the T slot aluminium works fine.

Ideally the grinding stone diameter should be larger than the grinder motor body diameter so you can flip the chisel and use the same stone.

I like the belt sander improvement

Jono, I omitted to compliment you on your version. My apology. Actually think that your blade holder would be better than the Veritas here as the magnets are stronger.

With some scrap aluminium, two magnets and a few hours it was done.

First I drilled two 25mm holes (to suit the magnets) in 4mm aluminium with a spade bit and then cut to size with a jigsaw.

The aluminium edges were filed with a body file - they are fast, clean and don't clog up - unlike normal files. The other item below is the adjustable plate that supports the blade.

The two magnets are epoxy glued in one at a time to avoid them jumping out with magnetic attraction. Also discovered magnets can be broken.

12mm rod mounting blocks are attached and adjustment screw added.

The old Titan chisel is ground and ready for work!

Very good result! It's hard to get much past 8" on wheels without getting into some danger or high cost.

I grind the bevels freehand on an 8" contact wheel on a belt grinder, but it's not really that important as the learning curve is maybe steep at first, the chance of skin removal early on is pretty high and everything with a contact wheel and belt and drive is getting expensive.
