flat chisel back - only at cutting edge or along entire length?

Page 1 of 4  
Hello,
I have a new set of Marples blue-chip chisels that is flat across the chisel face (as much as I can tell), but is slightly convex along its length, maybe about 1mm out at the end if I lay a ruler flat at the base of the face.
Is this slight convexity normal, or should I return the set? I am aware I have to "flatten" the face before honing, but with a slight round along the length, getting a straight cut by, for example, lining up a chisel against a block of wood clamped to your workpiece is made more difficult. Most discussions on flattening the face discuss the area right at and behind the bevel.
Thank you!
- Daniel

Return the set, the back needs to be flat. My own are like mirrors over about 2".

the tide seems to be turning against Marples lately. did I lead the charge? :)
(In my humble, highly unqualified, seldom respected newbie opinion, the Marples are tres substandard, due to the softness of the metal they are currently using; just like the Buck I tried for grins.)

You're bound to find that one of them will live up to your expectations.

I'll take you up on that, Charlie. I've been super busy lately; the only time spent in my shop lately has been to clean it up. I still would like to try your shoulder plane, too. I'll bring a couple of the Sears chisels so you can give 'em the once over.
I still have your phone number (surprise) after my hard drive crash. I'll give you a call next week, at the latest.
Take it easy...

Yeah, sure ... whatever ...

Well, you're right on two counts.

Well, just last week I chopped a dozen mortises (1/2" wide x 1" deep by 1-1/4" long) with one of my "substandard" Marples mortising chisels (the ugly plastic yellow-handled ones that Garrett Wade used to sell as a set). Didn't even have to hone the blade.
Then I used my 1" Blue Chip to do the final cleanup on the matching tenons. Yeah, it was only paring, but it performed exactly as expected.
I reckon I've chopped 50-60 sets of dovetails with my Blue Chips since I got them in late 1997. And guess what? I haven't had an edge fold yet, and the only time I chipped an edge was when I tried to use a 1/8" chisel in cocobolo.
I've chopped a hundred or so mortises of various sizes with the mortise chisels. And guess what? Not a single folded or chipped edge.
Of course, I guess I'm one of those wreck idiots, so what do I know?
Chuck Vance Just say (tmPL) I'll see your anecdotal experience and raise it.

no, you are just an asshole who can't figure out that Marples now suck. (An asshole for the tone of your reply; not for your reluctance to recognize that many people here share the same low opinion of Marples as I do. Bet you skipped those posts from approximately 10 other folks over several threads, since I first posted my experience with Marples. Or you just discounted their opinions as you did mine, you egotistical prick.)

Thanks, Dave. I couldn't have asked for a better response from you. First you call people idiots for daring to have a different experience than yours. Then you try to take credit for changing others' opinions. Now you up the ante and call me an asshole and a prick (egotistical, no less ... pot meet kettle) for daring to have a different experience than yours.
Truly outstanding work. Please keep it up.

maybe you should re-read YOUR previous super rude, egotistical comments. I only responded at your level. except for the name calling. Your attitude towards my recounting the facts of current Marples quality has been persistently RUDE.
And you still haven't responded to the fact that many others share my opinion.
Judging from your comments about "a better response", your sole purpose in posting your earlier comments were to piss me off, rather than to have a polite discourse on the topic of chisels. You reap what you sow.
Welcome to the FIRST spot on my NEW twit list. My hard drive crashed recently. I hadn't seen anything here to complain about in the past week, running without filters, but then again there were only a few guys on the list, besides all the filters for obscenities.
anything further you write will be for the consumption of your cronies. Talk to the hand!

Dave, you're applying a personal experience of yours inappropriately, and reaching a faulty conclusion. Marples don't "now suck."
Think of it like a car. If you bought a lemon, would you then conclude that the maker "now" produces nothing but junk? Of course not. Your one personal experience isn't a reasonable measure of the maker's entire product line.
I believe Chuck was trying to point this out to you -- that's why he included his yellow-handled Marples mortise chisel with his Blue Chips in his defense.
The truth of the matter is this: Various chisels having different levels of quality have been marketed under the Marples brand. (The same thing happens in virtually every large tool maker, including Stanley, and even -- hold on to your seat! -- Veritas and Starrett.) It's because the large producer must heed the market. The chisels you purchased are substandard (apparently -- I'm trusting your opinion on this). That's about all you can say.
In reality, the Blue Chips are a medium grade that will perform quite well for the average woodworker in ordinary use. Being a medium grade, some particular examples naturally will be substandard; some will be very good. The occasional blade will be excellent.
In general, they (the Blue Chips) are OK. The best woodworkers recognize them for what they are, use them appropriately at tasks for which they are suited, making sensible and reasonable adjustments to the edge and their technique so that the tools will work well enough to produce excellent work. They will not look back. They do this with virtually all their tools.
Many average woodworkers will find them satisfactory out of the wrapper and would give them no second thought, except to wonder what all the fuss is about. Finicky yuppie newbies with more money than need for the tool, and who "always buy only the best" will complain that the tool is junk, return it or throw it away, and buy a German or Japanese import of equal or slightly better average quality, while sniffing their superiority at the "lesser" mavens of the wreck who would defend a tool that does the job only adequately.

I would hazard a guess that you made this claim rather foolishly, having no knowledge -- nor even evidence -- to back it up. You're free to retract it.

Now YOUR response is the one that Chuck the attacker should have presented. You are correct that my chisel experience with Marples was limited, BUT if you go through the archives (don't bother) you'll see quite a few others to agree with my assessment of Marples quality.
No knowledge of WHAT, specifically? The edge crumpled after a few moments use. My other chisels don't do that! I've got 15 other chisels, all of which I can rely on.

And Dave wants to know...

No knowledge of what you claim in the quote above. To wit, "Marples are ... substandard, due to the softness of the metal they are currently using."
If you know it to be a fact, that the Marples chisels are now being made with a different metal than previously and that in fact this new metal is softer than what was used before, please do share how you came upon the information. I suspect you were merely fishing for an explanation of why your chisels failed. My suspicion is supported by the rest of your post:

for craps sake's Jim the proof is in the pudding, so to speak. I don't need to be a metallurgist to know that the chisel was a POS. If you saw the chisel in question, I think you'd be hard pressed to give it a passing grade. Same with the Buck. Their qualities were identical.
I don't know why you are obsessed with "proving" me wrong. In YOUR mind I'm wrong. so be it. Knock yourself out.

If you *were* a metallurgist, you wouldn't make a statement like you did. It's wrong, and it shows that you don't know much about metal, or specifically, how Marples makes their chisels and why yours didn't work the way it should. You're not expected to, of course, this being rec.woodworking. The problem is, you make an incorrect assertion as if it were fact, and then are surprised and defensive when you're called on it.
Look. It is ok for you to say, "The edge on a Marples chisel I just bought failed when it shouldn't have." You know that much. It's not ok for you to say, "Marples chisels suck now because they use too soft a metal." That is codswallop. Get it? There's no proof and no pudding involved. It's black and white. One is something you know, the other is meaningless blather.

I'm not obsessed. I'm not trying to "prove" you wrong. You were wrong all by yourself. I just pointed it out. You asked what I meant, so I showed you *why* it was wrong. You then think I'm obsessed with proving you wrong. Not at all. I'm trying to help you to be right. The fastest way you can get there from here is to admit your error (even if only to yourself) and move on.

Uh, no, in FACT, you're wrong. What I think or say has no bearing on the truth of the matter. Unless what you claimed were actually true, you were wrong with no help from me!
Cheers!

I'm waiting for you to post his reply. I've got him filtered, so can't read it without your repost, and won't change that, but I'm almost willing to bet...no, let's see what he says.

tell charlie for me he's #2 on my recently reconstituted twit list, ok? thanks!
But unlike HIS request to see quotes of filtered posters, I prefer you leave him hidden to me. I've gotten my quota of aggravation from him for a life time.
Now let's see if you honor my request...
