Sharpening wood chisels

[Welderpaul]

This is my set up for, primarily, my woodturning tools. It's a slow speed Axminster grinder with 200mm diamond, 40mm wide CBN wheels, fine on the left and coarse on the right. I did have a Sorby ProEdge system until I tried a CBN wheel on a cheap grinder - have since sold that on sadly as it would be ideal for the OP!

CBN (Cubic Boron Nitride) wheels balanced alloy with the CBN abrasive bonded to the surface. Virtually no heat build-up!

Paul Sellers on YouTube has some great videos on sharpening chisels using a sheet of float glass using wet and dry paper.

I presume the chisel is sharpened end on to the grinding wheel - does this not create a slightly radiused cutting edge?

Most of the chippy`s I know keep their gear sharp using an oil stone, they never allow them to get so bad they need grinding. Just sayin

I'm up to 5 sets of chisels now. 2 marples, soft and easily sharpened. 2 Stanley hard wearing but a pita to sharpen on site and a cheapo set for abusing more than the others.
When the last sets ruined its time to get the belt sander out again.

Usually use a 4 sided diamond block to sharpen/hone on the job. As per previous post just bought another of these.

Mine was pinched years back. Work very well.

You also need to buy appropriate bushings for your grinder; the Axminster grinder comes with 32mm wide grinding stones and I had to shoehorn the CBN wheels in by machining down the bushings and taking the angle grinder to the shrouds.

Rutlands do a knock-off version of a Tormek, not tried it though. — https://www.rutlands.co.uk/sp+8-wetstone-sharpening-system+DK7180

unless they hit a hidden nail or drop them or if you buy good quality ones at boot fair for peanuts and need to true them up before use

Always have a cheap set of chisels for work like that.
Nothing worse than hitting a nail with a freshly ground and honed chisel.

Due another sharpening session. Down to my last sharp set again.

Yes, it will produce a hollow grind - beneficial for woodturning gouges where riding the bevel is required. I haven't got round to setting it up properly for chisel (as in non-woodturning chisels) sharpening yet. I think I need to cut some more of the shroud away so I can get the correct angles using the Veritas jig you can see on the right hand wheel; the jig on the left wheel is for bowl gouges.

I use an oilstone and an simple eclipse honing guide just for a quick tune up, or for more serious, I use a bench grinder fitted with a wide white wheel.

This is the Paul Sellers video I referred to earlier - I've done some basic sharpening with it:

 

[Welderpaul]

This looks a good set up. Tormek T-4.

A bit pricey though.

 

[bigegg]

I have an older tormek - a 2000?

paid £50 for it off the bay about 4 years ago with a load of attachments.
paid for itself several times over.
I buy battered Marples/Irwin/Stanley chisels at the car boot for 10 or 20 pence, make them up into sets with a fresh sharpen, and knock them out at 10-20 quid a set.


just after a drill sharpener jig for it now - but they're about £150+

that's a *lot* of drill bits.

I have 35 year old India oil stone and an equally old if not older eclipse wheel honing guide. I sharpen all my wood chisels, planes and my recently purchased spokeshave with it.

they work a treat .no need for all the fancy pricey gizmos and unless your using the chisels 24 seven they rarely need sharpening just a quick rub

I've used the 'old school' double sided oil stone that I had when started serving my time [6 years then], still using it 50+ years later without a problem. Never needed guides BTW.

one of those, a sheet of glass or a big ceramic tile, and some 600-800 grit wet+dry sandpaper works really well.
start at 240 for badly damaged edges.

yes but there is 2 angles on a chisel and the much smaller angle is the cutting edge which is very small, so small that you will never notice a radius

 

[jordan1]

Just adjust the pressure to keep it square, comes easy after all these years, bit more difficult now the stone is not as flat as it was, doubt this quality stones are available now.

i remember watchoing a youtube video of a guy using a wide diamond file to sharpen knifes.
i would imagine it would do this kind of work really well
had a handle with diamond inserts that looked a lot like these https://www.skiservice-shop.de/toko...MIi7bf7P2Q3wIVDouyCh0UWAo5EAQYAiABEgIYK_D_BwE
and a jig where the knife was clamped up and the jig held the end of the file so when rested on the knife edge it sat at the perfect angle.
if i find the video i will post it up
