mortice chisels

[neilyweely]

OK, posted before and not sure where it went, so again;

I bought some Draper mortice chisels last week off the bay, and stipulated several times that I needed a 19mm shankn on the chisel. However, despite being assured they were, they weren't! So, I bought another set, cheap, and got what I paid for. They are terrible!
A friend, with a background in engineering, and the machinery to match (rolls royce for 50yrs), states that he could bring the drapers (20.6mm) down to required 19mm. I know Draper aren't exactly 'cutting edge' (excuse the pun) but they are MUCH better than the ones I got for 20quid. They are all 5/8 inch chisels too, so will all come in very handy.

So, folks, you know these sort of things (at least better than I). Will this work ok. I wasn't sure whether or not I would be compromising the balance or integrity of the chisels?
I know nothing of such things, but guess the fella I do know is an expert, just wondered what you all thought. I am SO skint (new house, new workshop - say no more!!) I really can't afford to spend more money on something if it can possibly be avoided.

Can it be done?

Comments?

Are you talking about hand chisels or as I think chisels for a morticer?

I would not have thought grinding/milling off 1.6mm would make any difference to the balance etc?

Why didn't you send the originals back for not being as described and get your money back?

Mortice chisels for a mortice machine, needed to fit out a solid oak kitchen.

Olly
Have already complained and got a refund of price i paid, just not postage. which kinda suits me, as I can either sell 'em or fix 'em. Hence post. If they are 'unfixable' then I will put 'em up for sale on the forum here for the price I paid postage. So someone will be happy at least. For the money they are really quite good - very solid, loads of steel left, good quality steel and well machined. So, not bad, all in all.

I think they should be ok thru a lathe, maybe mount 'em by sticking 'em in a lump of wood, and setting the wood in the chuck!??! Will this work, yes?

Thanks for your help guys,

Neil

Did you get the Draper Pro chisels or the diy version ?.
The Pro's are excellent, hold a very good edge.

If they are the Pro ones I'd get them machined down if you paid a good price for them.

I'm no expert on these things but if the friend can machine them accurately then I can see no reason why you would have a problem just machining the shank down, in fact, what have you got to lose?

Machining 0.8mm off the diameter of the chisels <should> be easy with a metalworking lathe. The only problem might be if the whole chisel is hardened and tempered, but I would expect that only the cutting bit would be. And since they are sharpenable with a steel cutter, even the points can't be <that> hard.

They are the pro version, to be sure. Very nicely made, and with a little kinda circular dent on 'em where they have been tested for their hardness, I guess. So, worth keeping, yes?

hpl, my thoughts exactly, should be ok, eh?

and Dick M,
This was what concerned me, are they going to be a nightmare to work on, as the steel looks to be VERY good, and I was concerned that the metalwork 'chisel' or whatever it is they use may be only as hard. Having said that, like you say; they are sharpenable, so should be able to work 'em down to required 19mm. I think they are worth the bother, as these things cost a fortune.

PLeased with what Gardenshed said, sounds like I done ok with 'em, as I said they cost the postage and the inconvenience. So it's settled, I will chance it with the engineer fella. Thanks all.

Finally, has anyone ever done anything like this before, and if so, did it work ok?

Cheers then

Neil,
I may be barking up completely the wrong tree here, but are you quite sure your chisels fit directly into the body of the machine? Many morticers have different bushings to accomodate chisels with different sized shanks. Mine has 2 bushes, one for 3/4" (19mm) and another for 13/16" (21mm or pretty close to) Is it possible you have simply overlooked this? If so it would be so much simpler to get your friend to make a new bush of the appropriate internal/external diameters.

 

[neilyweely]

blimey mate, you might be right. It appears to have a collet, which looks like it may be removable. am gonna look into it.

Back in a mo!

This collet looks quite thin, not sure if it could make any difference to put another in! Perhaps it is operable without a collet?? (bush)

|Where can I get these bushes, and would I have to have a nu tool one?
This bush may of course not be removable. It looks like it needs a special spanner to remove it, so will have to wait till Nu tool get back to me.

Thanks a lot buddy

Neil it should be easy for your mate to turn a bush for you as you know the outer diameter of the exisiting bush and the new inside diameter will be a sliding fit to your chisels. No you don't need one specifically form new tool if your mate will make you one.

Axminster used to do (still do as far as I know) a reducing bush to accommodate the various sizes of shanks available.

A quick call to their technical people will probably sort it out.

You will need to know the exact diameter of the receiving hole in the mortiser, and the diameter of the shank in the chisel.

The bush is almost certainly just a reducer, not any sort of special collet. If it's the same sort of fitting as my Multico morticer, you just need to take the grub screw that holds the chisel out completely, then prise the reducer out. It certainly should <not> be a press fit, because that would negate the purpose of it being there, which is to enable either standard sizes of chisel to be used.
If I still lived in Cranfield, I'd be happy to come and look at it, but the trip from Aberdeen would be a bit impractical

I would send them back as they are not what was stated and also Drapers tools are no big deal anyway. I bought some assorted Ward and Payne and Marples chisels all with boxwood handles for a song and they are superb.

Drapers tools are no big deal anyway.

Draper Pro range are very good quality, we use them here all the time now.
They keep sharp for a good length of time and give a good clean cut.

think you may be referring to mortice chisels with a handle (boxwood ?), of which I own some LN, one BS, some Ward and Payne , some Marples, Sorby (I and R), invicta, Nurse and Co etc,etc,etc......And no Draper. I am not 'doing a gloat', just demonstrating my flexibility!!! In fact I am not sure Draper make a mortice chisel with a handle, do they?

However, as stated, the Draper Pro range of mortice chisels for morticing machines are very good indeed. I have compared them to some others and they are very well made, good steel and well machined. I have no problems with them at all as far as quality is concerned. Nah, they are excellent. And I am impressed by them.

I do not use Draper hand tools, for no other reason than there are alternatives which are easily available to me for less money with excellent quality. But I am not a tool snob, and if the tool is good enough for the job, then it is good enough for me. I own Hilti and festool, and use Ryobi and sip. All good.

So,

Sorry to drag up a old post but could someone please tell me where they got there draper pro chisel set from and what I should be paying for them?


Thanks
