LW I've sent you a PM

 

[loz]

You have to quote the whole lot then delete the bit you don't want. No easier way.

Why didn't I think of that Thanks Wizer

LW

Just fixed that for you !

 

[duncanh]

Tekno - thanks for comments. I've got a Henry to myself, and generally keep it stuck under me arm :wink: , but I don't think any system will be effective. I mean, it hangs in the air for ages IMO.

An ambient air filter is what you need to remove dust (that's been missed by the extractor) from the air.
I use a Microclene 400. I vacuum its filter at least once a week using my Camvac. It's on pretty much all the time and you can see the airborne dust moving towards it.

.... Maybe it's a female thing, but I prefer the 'male' end on the lid, so you see a clean rim on the business end.........

LW, this can be a problem dependant on what is stored in the box, items have a habit of finding their way onto the recess ledge , or just overhanging it. this then stops the lid from fitting in recess.

With recess on lid anything contained in the box is held clear of the external lid locating recess by the spigot..

Hiya LW, nice boxes .... Realy like the Yew, its great !

What Duncan says about Camvac / Microclene is spot on for a 'reasonable cost' solution.

I have only got to the Camvac stage so far ... And its a great wee machine. Next stage is the Microclene bit...

My Cammy was , IIRC about £130 ( Delivered ), and ..well you'll know the price of the M/C's I'm sure ...
Still a reasonable outlay, but as Chas says, what price lungs ? ...
I guess we have to 'budget' these types of items into being part of our 'kit'.. as they are kind of essentials I suppose.

Can't speak highly enough of the Camvac... Its great.


Excellent progress on the boxes, though !
Looking wonderful ! 8)
Get yourself into the competition! 8)

 

[Lightweeder]

OK, ok, it goes on the list :wink: :wink: after the power sander, the hollowing tool and the buffing system. Oh, and the sharpening jig - and the new 5/8" gouge because I sharpened the b*****y out of the other one :evil:

At my age, something's got to get you :roll:

I hear what you say Chas. I promise to try it your way - one day :wink:

 

[mark sanger]

Good work lightweeder.


Nice boxes, well done.

I have skimmed over the thread so apologies if this has already been mentioned.

Have you ever seen or used collect chucks. I make mine out of ash/oak and use a jubilee clip. Then you can put you box lid in them and tighten the jubilee clip and compress gently around the box to finish off the base etc.

I will post a pic if it helps.

I remember seeing something using a jubilee clip mark. Yes, would much appreciate a pic. Thanks

Thanks all for dust extraction advice. So.... can I get away with the Henry (which is actually quite powerful) and a small suspended Microclene :?: Jenx, the camvac does look good, but I can't have both and it looks like the Henry might do for the immediate dust, while the Microclene does the ambient dust. Sorry to drone on, but does that sound reasonable :?

 

[wizer]

That should be fine. You'll be surprised how much the Microclene takes out of the air. Just have Henry on when you're sanding. He'll die if you try to use it while turning.

What have you got in the way of a mask?

 

[mark sanger]

Hi Lightweeder

You must get yourself a mask.

If you buy a cheap halogen 50 bulb/light on a bendy arm, they sell then in Focus. Shine this at an angle away from where you are working. If you see dust particles in the beam you should be wearing a mask.

Don't buy the disposable paper/clothe ones they are a waste of time for wood dust. You need one with a valve. They are a bit uncomfortable but I expect more comfortable than carrying round an oxygen bottle.

If you look on a dedicated woodworking/woodturning shop website then they will have the best ones to get and explain it in detail.

And lstly don't take your mask off once you stop sanding/finishing as it will all still be in the air.

Sorry to go on but it is important.

Any way on to the collet chucks.

Made of Ash/Oak or any similar hard wood

this one here is 70mm dia x 90mm high with a 60mm recess.

Turn the basic shape between centres,

turn a spigot to fit you chuck.

Put it in the chuck and drill it/turn it out to a depth of 55mm and inside dia/hole of around 48. You want the wall thickness to be about 10-12mm to flex.

turn a recess for the jubillee clip to go round

Then turn a shoulder inside to take what size boxs you normally make. this one is 55mm.

Most box makers standardise the sizes of the boxes they make and have set size collet chucks and templates for form etc.

Then put your jubilee clip in and mark how long the screw/tightening mechanism is. You then take it off and carve away under this as in pic 4.

If you do not then the metal band under the screw will push one side in more than the others and it will not run on centre.

Then using a suitable jig/wedges to cut circular material on the band saw cut twice at 90deg to each other down the length. This will make the four slots ( make sure the carved out bit is in the middle of one of the side.
You can cut the slots around 2 mm wide. This will give you quite alot of clamping movement.

Then make your box to fit the collet. Pop it in an tighten it up and you can finish the bottom/top etc.

You can make them any size length ( within reason) and change the recess depth inside to suit. If you make the distance from the jubilee clip to the front face around 25 mm then you can skim it out and back quite a few times if needs be to fit different sizes before you need to make another.


Hope this helps. If anything is not clear just ask. I will get back to you after the weekend as am away working over the weekend. I never knew turning would mean so much driving.

It never said that in my Lathe instructions !!

 

[CHJ]

I am sorry to keep banging on about this but as Mark says, if you can see dust in the air, or settled on a surface anywhere in the shop as a result of your turning/sanding then you need a mask that works.

An air cleaning filter is good for keeping a cleaner shop as far as removing dust that can spoil a finishing process when disturbed but you must remember that if there is dust for the cleaner to collect then there is dust for your lungs to do the same.

Even cleaning mask or cleaner filters with a shop vac is suspect if your vacuum cleaner does not have fine enough (hepa?) filters to prevent re-distribution.

 

[duncanh]

If you can't afford a powered respirator then how about one of there designed for MDF. It's like what I used before I got the powercap.

When I used it I put a piece of kitchen roll over the filter to act as a pre-filter. The speed at which it got coated and needed replacing was alarming - round about once per week.

[wizer]

I'm not sure we've established that LW is or isn't already using a mask yet.

 

[Paul.J]

LW.
This piccy shows the very fine dust,that looks like smoke,coming from drilling the timber,and as you can see it is been drawn into the dust pipe that is still a few inches behind where the drilling is taking place :shock:
If the extractionj wasn't there the dust would jst be thrown round all over by the lathes speed.

 

[Lightweeder]

Oh lawdy :shock: I bought an expensive mask, but my glasses steamed up and I couldn't see what I was doing - not a pretty sight

Duncan - that mask that looks like it's designed for germ warfare wouldn't go under my welders' mask. Otherwise, that would be just the ticket :!:

I'm taking your heed and buying a proper system, but I've only got half a garage, so I hope I can get away with something relatively modest. If not, then so be it. I'll get it. But do I have to buy the two, ie the extractor and the ambient air thing. Can I get away with the MC100 suspended over the lathe, and the Henry stuck up my nose :evil:

Need your help. Thanks

LW

 

[Lightweeder]

Mark - thanks for the post. I can work something 'round that. Much appreciated.

 

[jpt]

THESE are good masks and fit under full face visors.

I also wear glasses and used one of these for about a year before getting a full face air mask. They vent out of the bottom of the mask through a valve so dont mist glasses.

How much can you actually see through your welding mask? Don't most of them have just a small glass part in front of your eyes?
I know it's more to spend, but I used one of these flip up safety visors from Axminster. Only £7 (plus postage, of course). Also useful around the garden when strimming or using the hedge cutter.

You probably could get away with just a microclene and your Henry, then add an extractor when you have some of spare cash (hmmm, if only!).

I'll try to remember to take extractor, microclene, visor and powercap along next week if you want to check them out.

 

[Lightweeder]

What I call a 'welding mask' is really a full-face visor, so Duncan - similar to the one you showed me.

John, I think that also looks like an option, but it doesn't get rid of the problem of ambient dust.

Duncan - thanks for the offer to bring your kit along next Saturday, but please don't go to that trouble. I can just imagine how much hassle that would be - I'm coming to the conclusion that I'll get the Camvac, used with a decent mask, and if that doesn't seem to do the trick, I'll add the Microclene on later.

Much appreciated lads - thanks.
