Hi all, here's a little tale of woe that hopefully one of you illustrious and more experienced woodies out there can help me with.

Since Wed last I have been the proud owner of a brand spanking new Jet JPT planer thicknesser (insert envious snorts here) purchased from APTC for the not inconsequential sum of £1,349. However (you just knew that was coming), all is not well in Welling.

After drinking in the impressive sight of the HUGE packing crate for some time my big mate Simon and I set to with with numerous planks, beams, chocks, steel bars, scaffolding poles etc. Several hours and more then one heart stopping moment later we finally persuaded the beast safely from it's perch on a 5" pallet to the workshop floor, and thence onto the mobile base. Furious, but careful, work ensued with rags and solvent to get it cleaned down ready for action.

Now all I needed to do was fit sharp knives (the ones that came fitted looked like they'd been ground on a concrete doorstep!), check everything for squareness, plug in to my dedicated 16amp circuit, and get stuck in.

Problem was, when I put my engineers square up to it to square it to the table, I could clearly see it was only touching the face of the fence at the top and bottom edges. On closer examination with feeler gauges I measured a .35mm gap between the midpoint of the fence and the blade of the square. Of course I contacted Axminster who immediately agreed to replace the fence, along with one of the support brackets that was also duff.

Well, the replacements arrived this morning. In fact what I was sent was a more or less complete fence assembly including all the support arms and brackets, that had been removed wholesale from a machine in store. Although a bit grubby and clearly secondhand, the brackets look fine at least within what one can reasonably expect from pressed steel items with no machined faces to slide on. The replacement fence extrusion though is another matter, and is every bit as dished between top and bottom edges as the first, if not worse (this time I got a .4mm feeler gauge in the gap).

Once again on to technical at Axminster who went to their resident Jet engineer. His opinion is, in a nutshell, this:

1. He could not guaranty in any way to EVER find one that was bang on flat, if he could he'd have one for his own machine. The machines were made to a price and some sacrifice in quality more or less has to be expected.

2. I could make a hardwood facing, of Oak for example, and attach to or replace the existing fence extrusion.

I have to say that, despite my best efforts to remain philosophical about all this, I am less than inspired by either of these comments considering how much I paid for this supposedly "industrial" rated machine. I have long held to the beliefs that "you get what you pay for" and "cheap tools cost more in the long run" and therefore my question is this:

At what point does a tool cease to be "cheap", and more specifically, what is a reasonable expectation of accuracy in the manufacture of a machine at this level?

Axminsters technical chap, incidentally, suggested a fix; he would uplift the machine and sell me a comparable Rojek or Sedgwick model instead, with a bit of discount as a sweetener. I know he's only trying to help, but when you've parted with this kind of money on machine you don't really need to be told you haven't spent enough for it to do what it was designed to do.

I can't tell you how much I looked forward to getting the Jet, and I'm still confident (just) that I can get it to be the machine I thought I'd bought. But at the moment I'm a bit too despondent about it to think objectively, so I would welcome any and all comments and opinions.

Thank you
Mark[/b]

If you are talking about the JPT 310 I bought the exact same machine last year. I have to say that I have not experienced any vertical bowing in the fence. I did the set up with engineers square and all looked ok, mind you my eyes may be a little suspect.

I will check my machine when I get home later this week to see if mine is the same.

I have used the PT extensively in both modes and in jointer mode I can only say that I get a perfect 90 degree. Thicknesser mode also gives good results.
I don't think you will be disappointed with the machine, although I'm a bit disappointed with the Jet Reps comments, on a 500GBP machine I could understand it but not for the price of this machine.

My advice would be to test run the jointer extensively with different size of wood up against the fence and see if it makes a difference to the squareness, after all you're only talking about 0.35mm.

I'll let you know later this week when I check mine again.
 
Mark,

My sympathies, I have had a not dissimilar experience with my Schppach TS2010 table saw.

Before I go any further I should emphasise that I am not a legal expert and what I am writing is only understanding, however I think you have just cause to send the planer back.

There is some protection under the distance selling act which means that you can return items which do not match the advertised performance. There is also a point concerning the sale of goods that they must be of satisfactory quality. Under each of these points there could be some counter argument and then there is the point of returning the item. Did you keep the original packaging :? and what about the postage :shock:

You will also be without a planer for however long it takes to resolve the issue.

You could try and escalate the matter with Axminster, they are the one's you have the purchase contract with. Try phoning and asking to speak to the MD or Sales/ Marketing Director, better still if you can find their names first. Depending on how things go you could threaten legal action because the goods are not of "satisfactory quality". But if you are going to do this do it NOW.

The other option might be to take the fence to a local toolmaker and get a price for them to skim the fence face, I assume it is cast iron. You will probalby end up with a better fence than any that Jet could supply.

If you are generally happy with the rest of the machine this is probably the line of least resistance. If you go this route I would probably write to Jet HQ and tell them what you had to do to make your product work.

In my case with my the table saw, due to illness it was several months between the saw arriving and me setting it up, hence I decided to fix it up myself. As a result I spent hours getting it 'right' and am still slightly disappointed with some aspects, but then again I am a fussy so and so :wink:

Not sure if this is any help, but you asked for comments :)

Cheers,
John.
 
I thought I would throw my tuppence worth in Mark, for what it is worth. I think you are justified in wanting value for money and as I think you have pointed out, the machine is not fit for purpose. What the Jet rep is hoping is that you won't be bothered to go to all the fuss of returning the machine.

If this machine was being sold in Germany for example do you think they would put up with that reply, how much do you have to spend on a machine before they think it should be ground to precise tolerances?
To be honest I have just bought the Axminster cp150 and the fence is cack, but then I bring into question my ability to set it correctly, as well as the fact that it only cost £140.

However, could I reasonably expect the fence to sit true at the 90 degree position when you tighten the nut up? And at the end of the day my tolerances are far worse than the majority of the members on the MB, it is only their perfection that makes me want to achieve better results.

Rant over :D

sorry to hear that not all was well in Welling Mark.

Where abouts in Welling are you? I have a large amount of hard wood that needs thicknessing if you want to give it a good rigerous test ;) :p
 
I think you should return it and get your money back its the only way to halt the falling standards of accuracy .
I can remember reading a article where the sales manager for jet in britain said that customers could rely on the fine tolerances in jet machines .
How hard is it to find a good fence or machine one correctly.If the number of returns go up they will fix the quality problem.

I'd be happy to run some through for you as long as you don't mind waiting for a week or so when I'm less busy, and front up a little to cover the 'leccy and any necesary blade regrinding. PM me.
Or, of course you could always just come round and buy the deWalt that went on Ebay this morning. :wink:

Thanks everyone else for your comments, keep em coming I think this will run for a while. I've got some specific replies to people but no time to type them up at the mo'. Maybe later this evening.

Mark
 
hi mark, sorry to hear about your problems. Is the fence and aluminium extrusion or a solid steel plate. I have the record p/t with an aluminium fence and i have the same problem. found it was due to the way the fence was fixed to the tilt mechanism. When tightly bolted up the bolt was pulling on the centre of the fence and tended to force the fence into a concave shape. Try checking it without tightening the tilt handle up and see if this remedies it? i don't find it too much of a problem to be out, only when machining narrow boards.

Hi Mark

Sorry to hear about your problems.

I have the Jet jointer and I think it is the best bit of equipment in my workshop. I absolutely love it.

I've sent a pm to JetMan, Nick, asking him to look at this thread.

Cheers
Neil
 
Sorry to hear you're not happy with - kind of takes the edge right off the whole retail therapy thing doesn't it? Yes it's a lot of money, yes it's built to a price, yes you could get another machine or your money back, but have you tested it for accurate results yet?

Ike
 
Hi Mark, Apologies you are having problems. There's not much I can do at this time of night, but I'll look into this tomorrow for you.

I'm not aware of any other problems like this on the JPT310, but I accept that you do seem to have an issue. As you rightly pointed out, it is sold within a price bracket that means it should be built to a certain standard. I’m going to contact the chief engineer of Jet in Switzerland to get his views on acceptable machining tolerances - I will let you know.


I may not be able to reply now on here until late tomorrow night, as I'm working away tomorrow.

If I can help out I will.

Best regards,

Nick

intregueing isn't it that on a machine which is designed to cut wood
square to an edge, the fence should be suspect.

but as elsewhere, there are problems in most machines with fences.

rather like the base of a hand plane, how expensively do you want it
to be flat.

do you have a straight edge that you have run from one end to the other
of the fence and thus is that flat over the distance, and is it flat over that
length? not sure whether it matters over the height of the fence, since
you would expect that your edge would run along the bottom of the
fence, and thus the concavity should not affect the squareness of the cut.

i agree though that it is disappointing that the fence is bowed visibly,
but maybe it helps with stopping kick back :? :lol:

i would tend i think to try and sort out a few bits of different sized wood,
check with your engineers square whether the edges are square to one
another. then you can send to axminster some of the offcuts to show how unhappy the planing is, in which case you could negotiate a rebate for instance, but it is possible that you would want to use a replaceable
fence face anyway, but to have it forced on you is a bit of a bummer.

Hi all,
thanks everyone for your support and comments, knowing I have this kind of combined wisdom at my disposal is extremely comforting to say the least.

I'd like to clarify a couple of points because I feel the mood I was in when made the original post (and my interminable rambling) may have clouded the issue somewhat.

First and foremost I may have given the impression that I have a grievance with Axminster and/or Jet regarding the standard of customer sevice and the machine respectively. This is not true, and the way things are developing seems unlikely to become so. I certainly am nowhere near a situation where I would consider threatening legal action as an appropriate course, and I would like to apologise to anyone who got the impression I was that upset.

Despite a couple of rather odd (and as Nick put it "undiplomatic") comments, Axminster have been prompt and courteous with their attempt to rectify things - remember the replacement parts only arrived this morning - up to and including an offer to uplift the whole machine and replace it with a similar model from another manufacturer at a discount price. They have also given me until the end of the week to make a decision, during which time I intend to make time to take their advice (and similar advice from members here) to test the actual results from the machine after fitting the best combination of fence parts currently available to me.
Meanwhile, Jet are also on the case. And thanks to this forum, much quicker than I could have hoped for. The machine itself is, I still firmly believe, the best choice I could have made given my requirements and budget, and essentially sound save for this fence problem. I have every reason to think that once it is sorted out (and I'm sure it will be) the machine will go on to give me many years of faithful service.

As for the fault itself, it seems I left out a salient point in my original post. I'm guilty of forgetting that I'm the only one who's been obsessing over this purchase for the last month or so, poring over the catalogues and driving up and down the A2 to study every detail of every machine I could lay hands on.

The fence itself is an aluminium extrusion much like on almost every other machine in this class so there is no "machining tolerances" as such involved in it's manufacture. And because it is aluminium and the walls of the extrusion are only about 2mm thick I don't think having it machined flat is an option.

I'll let you know later this week when I check mine again.

Thanks Waka, I'd appreciate that. If yours is flat maybe I've just been unlucky - bad batch or somesuch.

When tightly bolted up the bolt was pulling on the centre of the fence and tended to force the fence into a concave shape. Try checking it without tightening the tilt handle up and see if this remedies it
Been there, done that, no joy. good idea though.

but have you tested it for accurate results yet?

Ike
Ah.. no, not yet. But if a 150mm high fence is bowed i just dont see any way it can produce the same angle on the edges of 2 pieces, one 75mm wide and the other 150mm for example. They simply have to be different because the bow will cause them to be held at a different angle relative to the table.

Thanks again for all your comments, and your patience with what has turned into another rather wordy post. I'll see what happens over the next few days and post any results worth talking about.

Cheers

Paul, we appear to be at cross purposes here. The issue arises when planing the face edge not face side. For this the flatness of the fence between the top and bottom edges is absolutely critical to getting a consistent angle between these adjacent faces. Imagine using a shooting board that presented the plane to the timber at a different angle depending on the width of the timber. That's exactly what happens on a machine with a dished fence when the face presented to fence is narrower than the height of the fence.

Mark
 
I recently bought a Charnwood p/t and have the exact same problem, it cost me £385 so the cost of the machine seems irrelevant, except the bow on mine is over 1mm! Perhaps the extra grand is worth about 3/4mm.
I have thought of fitting a false fence but it needs to be at least 1'' thick to stay straight, which would make it a 9'' planer not a 10''.

I hope you get yours satisfactorily sorted out and will watch with interest for any fixes.

If there are manufacturing tolerances on this type of product should the manufacturer have a duty to state what they are in the technical spec?

Good point Andy, and goes pretty much to the nub of my original query - maybe I should have titled it "How straight is straight enough?". Just about every component of everything ever made starts life as a drawing with dimensions and tolerances, otherwise Quality Control could not exist. What I would be interested to know is what those tolerances are for this item. I'm due to speak to JetMan soon so hopefully I will get a definitive answer on that, and then I'll have a much better idea of where I stand.

Mark
 
mark, sorry when i first read i wondered whether that lengthwise was the
problem.

however i am not convinced that the bow is as damaging as you think.
as i said, as long as the wood hits in the bottom right corner,
then the rest should be fine, but happy to be proved wrong :cry:

paul :wink:
 
Paul, I wish I knew how to post pictures - this would be soooo much easier to explain with a drawing. The problem is the fence is concave from top to bottom. Since you apply the force to the fence rather than the table when planing the edge, timbers of different heights will be presented to the blade at a different angles depending on where the top edge of the timber touches the curve in the fence.

Hope that makes things a little clearer.
Mark
