Chisel and plane iron honng - Convex bevel

[Benchwayze]

Someone who believes in a 'rounded' bevel on Chisels and irons.
Is there something in what Jacob says?

I am going to try this on a couple of my old chisels...
(Can't say I'll be investing in Diamond stones, but I'll report back next week. )

The only surprising thing is that so many people are surprised by it!
It's just normal sharpening fer crissakes! It's "modern" sharpening that's gone peculiar.
Usually done with double sided oil stone, sufficient for most purposes, but Sellers is being a bit more thorough.

If you actually look carefully at what he's doing, the back of the blade is being lifted :shock: on the strop. The paper cutting test is a good one, but the chisel isn't really cutting it cleanly as far as I can see. A nice demo but once you see through what's happening it's not all that impressive IMO. Using a Kell guide is almost as quick and I don't need to strop the edge about 30 times as it's already like a razor, the stropping just refines it a tad...two or three times is enough - Rob

As a fair beginer at sharpening I was suprised to see the burr being removed with a sideways motion at the end, is that common?

I've always done it that way or very similar.

Well I dunno, but I fancy if a neophyte came on this forum and said they needed to do that much work on the strop after their "fine" stone, I'd be advocating saving up for a finer "fine" stone. Other than that, well whatever rocks his boat. In its own way, it's as crazy to me as the lengths of precision that Mr C goes to, but as long as we all end up with sharp edges so the surgeons can fix out digits back on with the minimum of fuss, that's the main thing.

Well Alf, cant say the surgeons reattached a digit, but one did spend 1 1/2 hours sewing back a severed nerve on my right thumb (you would not believe how awkward it is with little/no sensation on the outside edge of your dominant thumb!) after I managed to slice it on a random tidy up. Wasnt even doing any woodwork, just picked up a chisel roll and placed it on the shelf, not noticing the chisel sticking out. There was a moment of 'oh bugger, Ive done summat there' and a fair bit of bleeding, and a very embarrassed moment the next morning at work when I presented myself for the theatre list rather than just running it
Anyhoo, I'll stop rambling now. Oh, and it was a flat bevel, none of this antiquated rounded nonsense

You can do it how you like!

Well yes he is overdoing it - I guess he feels he has to to be credible; mustn't make it look too easy!
Infact for most purposes his middle stone would do.

I was thinking exactly the same about the extreme stropping, a couple of strokes is all that's needed on a suitably charged strop.

As it happens I've recently been using 1micron diamond paste on my leather strop (£3.50 from arceurotrade before Anybody tears into me for spending large ammounts) and the results are very impressive indeed! Try it, there's a good chance that you'll be as impressed as I am!

Thanks for the replys

Paul seems to spend longer stropping than my whole sharpening process takes.
(About 1 minute 30 seconds on a good day).

I use two stones with a third (old fragment) to raise a slurry on the 800grit stone.

One of those dangerous and complex mechanical devices, (an Eclipse guide) maintains consistent angles.

The process is clearly explained and demonstrated on my 4th DVD.

best wishes,

I've never hurt myself to any degree in a Woodworking situation, But when I was an apprentice, I did cut a huge gash up the inside of my forearm, when a spanner slipped as I was setting up the tooling on a turret lathe. That just missed an artery but didn't need many stitches. The most dangerous hobbies that I've had in the past (apart from falling off motorbikes!) are Fly Fishing and Cricket!

Actually the major Cricket one was quite incredible! I was skippering my local village team against a team just off the A40 near Burford. They had a bloke who just had a huge go towards mid-wicket at anything he could. I put two players out on the mid-wicket boundary and then put myself (never ask anybody to do a job you wouldn't be prepared to do yourself Ho.bleedin' Ho!) at mid-wicket about 15 yards from the bat (basically in case he got a top edge and skied the ball). About 10 minutes later he hit one going like a rocket at chest height and just to my left. The next thing I remember is looking at my right little finger to see the end virtually hanging off and blood literally pouring out. As it's such a lovely Ground for the Family, I had a Wife, two dogs and all the associated paraphernialia for a nice picnic at the Cricket to collect and charge off still pouring blood through we'd found to wrap round itto Burford Community Hospital where they called in the local MD on callout for the day. He took one look at it and my Wife at the time swears to this day that he went green and looked like he was going to be sick. He then said that I should go straight to the John Radcliffe. So we get to the Radcliffe (with 2 dogs, etc.etc.) and A & E was heaving! So I sent Wife and dogs home and said I'd call her when finished. After a two hour wait and a couple of x-rays, the Doc. says (and I'm not joking here) "I can put back the dislocation in your thumb and the two! dislocated knuckles in your little finger, but the tissue damage I'm not capable of handling, so I'd like you to show up as early as you can after 8am.at the Plastic Surgery unit at the Radcliffe infirmiary (middle of Oxford) So I duly turned up as instructed and several hours later I was shuffled in to see the Surgeon, who turned out to be an Australian, pretty much of a sporting age and build. He said "Oooh. that's pretty nasty, how did you do it?" So, I explained it to him and as you will probably have worked out by now, he asked "Did you catch it!" He put 27 of the most intricate stitches in it. The end of tha little finger is about twice the size and pretty much nerveless, but I can still bend the finger!

The Fishing one is far less dramatic, but somewhat of a comedy. I was trout fishing on Exmoor and had to present myself at the Doctors Surgery with not one, but TWO flies firmly embedded in my right ear! While he was looking it he said that he was well used to removing Flies from Fishermans ears, but never two in one ear!

When I was teaching I used to horrify the kids about chisel safety...and the true story goes thus. Once upon a time a woodwork teacher had a very sharp chisel in this hand, which he thereupon put into the pocket of his traditional carpenters apron. He then had some sort of accident (fell, or maybe knocked against the bench) and the chisel went through the apron, through his trousers, down into his leg...and neatly sliced through the femoral artery.
He lasted about 30 seconds...took a bit longer than that to clean up the floor :-& True story - Rob

 

[Benchwayze]

Very interesting Tony. Quite a story... I certainly wouldn't want to experience that. But it's a shame you happened to pick on fly-fishing and cricket; two of the most pointless pastimes I could imagine! Cricket? Aside from the boredom of it, I couldn't stand the peaks of despair and jubilation, our lot give us. And the fly fishing? That's about the only thing I don't like about DCI Christopher Foyle!!! :mrgreen:

Oh! I have had my regulation, three episodes of 'dropping' a motor cycle'. I got away with it except for a bruised posterior and a few scrages.

Please note folks, I do NOT want to hijack this thread, so I'll reserve my 'chisel' story for another time.

Oooops! Sorry Rob... That really wasn't intended as a poke. I just realised it could be seen as such! (And only a fool would put a chisel or screwdriver in a pocket. )
:?

Out of interest, when was this? In about 1973, I was in the JR having tendons in thumb sewn back together, and while the surgeon who did it was brilliant, I wouldn't like to have been treated by his Oz understudy!
