Blockage with maple

[Waka]

I was planning down some maple yesterday on my JPT 310 and found that when planning the shavings were coming off in quite long lenths width wise, this presented the problem of costant blockages in my 100mm extraction system.

My present extractor is the Schapach 2600, and I'm thinking that I may need a more poerful machine. Has anyone else experienced this while planing maple, also can anyone recommend a more powerful machine to overcome this problem?

It doesn't happen when planing oak or cherry.

Have you thought about going larger than 100mm? That will possibly be cheaper

Hi Waka

Have you thought about one of those dustbin lid interceptor thingies that Axminster do? Should stop the bulky stuff from getting to the blockage point and a lot cheaper than a new extractor - about £20 plus a cheap bin to put it on and an extra bit of hose.

Failing that, do what I did on my old extractor and take a pair of snips and remove the webbing from the inlet port.

NOW HOLD ON all of you who are about to vilify me for this apparently cavalier approach to safety and let me explain.
1. I only did this as a last resort, my extractor was a little underpowered and the blockages were happening so often as to be a real PITA.
2. I work alone and so I'm the only one at risk
3. I know NOT to stick my hands up the intake port while the machine is even connected, let alone running!
4. I only did it because the machine was only used with the PT, so no chance of picking up anything larger than a shaving that could damage the impellor.

I have also had to remove the baffle (on the SIP) extractor and the only set back if doing this is if you use the extractor for cleaning up the floor or deck when not connected to a machine. Any solid debris hits the extractor fan fins so I anticipate one day some internal damage?

Mark, I did the same thing. Mine is used exclusively on the P/T and only by me too. And I reckon it was more risky having one eye on the dust-ex when using the P/T than removing the grill and being able to concentrate on the job in hand instead of the blockages.

I believe that the grilles are a manufacturing approach to stopping people shoving fingers into unconnected hoods when the machine is in use. They may also serve some function in stopping bits of broken blade from being ejected, but quite frankly I fail to see their purpose on machines connected to a DX..... :roll: Possibly a case of overkill?

Scrit, the grille's on the dust extractor inlet rather than the P/T (unless I've got the wrong end of the stick?). I can see the point, if only it'd let the actual wood chippings through! #-o

[devonwoody]

minor point but the baffle plate gives a small support base for the tube and jubille clip to stop crushing of inlet?!

To stop you putting fingers into the impelller? :shock:

But if the inlet is circular and of sufficient diameter why would it need a support? I thought that by their nature cylinders are naturally very strong

I guess I should have explained more clearly in the first post, the blockage is on the take off of the PT which is 100mm diameter, I've not experienced any blockage in the hose to the extractor, so gong bigger diameter I don't think will solve the problem

I certainly don't want to fork out and get a bigger extractor becasue my 2600 has given me really good service and is excellent on all other types of wood I've used, it's just the maple. I've even tried taking off very small amounts and it still eventually clogs up.

Hi Waka

It's that Alf trying to tanglefoot me again! :wink: I don't have anything like that on my P/T, but my large spindle used to have just such an arrangement and it was a royal pain on some materials. The solution was to attack the cast alloy "prongs" with a hacksaw and file to shorten them I suppose the other solution might be to stop using maple, though..... :wink:

Waka, I was also under the misconception that the blockage was at the DC intake. I have the same PT as you (lovely aren't they) but the only time I have had any build up of waste in the hood was when I already had a blockage at the DC intake thus knocking down the airflow. This prevents the chippings being drawn out of the hood properly and then everything backs up.
There is a swingover baffle affair inside the hood on the JPT310, you can hear it go clang when changing functions, it's to alter the airflow path inside the hood depending on it's orientation. It's just a thought, but maybe it is jammed partially and not directing the airflow properly, I reckon that would stand a good chance of having the effect you are experiencing.
One other thing: how deep are the cuts you're making? Could it be "sheer weight of traffic" as they say on the M25?

See, Scrit? No tanglefooting 'ere niver. O And yeah, not getting your fingers in the impeller is a Good Reason for the grille but without the grille I'm not having to remove the hose every five minutes and am thus further away from the impeller and therefore the danger. However, while it makes sense to me, I absolutely don't encourage anyone to take a hacksaw to their dust-ex like wot I have done, so if you stick your hands into an impeller having done so Don't Blame Me.

Hear hear, Alf!

Silly question, but don't most folk use a hose on their dust extractors? You'd need 10 foot fingers to touch the impeller. Or do you lot use yous in a different manner to me? :wink:

....foot fingers? aren't they called toes? (groan)

[Alf]

Groan indeed... Makes a change that it's not me causing it! :lol:

Phil, you've put your 10 foot finger on it. If the thing doesn't get blocked, the hose is twixt you and the Bad Place. But when it gets jammed up round the grille, well you take the hose off to clear it, don'tcha...? Uh-oh, as the Health & Safety boys so often say, or words to that effect anyway.

Nice to see this post has some idle banter attached to my maple problem.

yes I guess I coud stop using it but it is such a nice wood to work with. As for taking too much off at a time I tend to do everything in small increments. Looks like I'll have to take a lookat the vanes in the hood.

Thanks all for the advice and scintillating conversation.

As for mods to the extractor, this would be like removing the guard from the table saw, and I'd never do that

We'm obverussley be 'avin longer fingers than ee.... :wink:

"Scintillating"? LOL

I nearly believed you then-NOT! :lol:
Seriously, I hope you gleaned something from all this. And glad to see you haven't lost your sense of humour. :wink:
