Im in the process of setting up some dust extraction for my lathe and purchased a big mouth hood - was going to buy the axminster floor stand to support it, but decided at nearly £100 it wasnt worth it.
Anyway after a bit of pondering and searching online I came up with this:

If anyone's looking for a solution to supporting their hood, this is really cost effective - fully adjustable Monitor bracket which is currently available from Ebay or Amazon for £18.99! - I know.. theres no Vac attached yet, but hopefully thats coming soon

Terrific support. It will take a wacking great suction to feed the hood. Show us some pics after its installed. Using my vac systems I have to use ear protection. By showing I have a heap of shavings outside the vac after turning pens.

how effective is your hood? Are you using it for sanding only, or chip collection too?

! currently do not have extraction on my lathe. Once in a while, I clear up the shavings. I dont turn bowls, so do not generate huge quantities, but it does amount up over time. I have wondered about fixing a hood to my lathe and the other end to a camvac, but it isnt really at the top of the list yet.

The support is a great idea Burt, out of interest what size extraction unit have you ordered?

You will need allot of airflow for that hood, or it will need to be extremely close to your workpiece on th lathe.

Hi Mark

Don't have the vac yet so can't say how effective it will be but thinking of going for twin motor camvac which will be primarily for sanding (I don't mind sweeping up shavings)

i have the twin motor camvac. It certainly has some suck on it. It is a shame that you arent nearer so we could try it out.

I like that idea a lot. Looking at it I would buy a Locking lever to make it easier to raise and lower on the support.

Extractors with a set up like this will not take all of the chips away unless you can direct them into the mouth of the hood but if sanding correctly IE from the bottom it will take the dust away. But then that is what you want removed. I still have a pile of shavings at my feet after a good turning session, which is something I could do with right now.

That's a good idea. I have mine on an anglepoise are but my hose is only 63mm, yours looks like 100mm. I have the twin camvac & it works fine.

Take a guess
Great money saving idea on the stand :thumbs:
I use the same hood on the back of my lathe but ended up cutting it down as there was too much loss of suction from the inlet at the back to the front edge of the hood though mine is on a LPHV extractor rather than a HPLV extractor like a Camvac.

I'll be interested to learn how you get on with it.

That is a concern as your cam vac unit is 108 lts/sec works out at 388 m3/h when most HVLP units start at twice that volume. (base calcs on 1lt/sec at 3.6 m3/h)

You can only try it out and see what happens but would be interested in what you get.

low pressure high volume- the bag type extractor, usually for chips, e.g. off a planer thicknesser
high pressure low volume- the vacuum cleaner type extractor- usually for fine dust from saws, routers etc

LPHV? HPLV? Anyone?
Click to expand...

Chip extractors (fan units) are the Low Pressure High Volume (LPHV)

The Vacuume units are normally High Pressure Low Volume (HPLV)

The vacumme units normally have the high filtration rates filtering out fine dust.

The fan systems normally have the bags with low fiktration rates and don't take out the fine dust. Filter cartridges are available but do effect the flow rates through the fan systems.

Hope that helps phill.

Edit.. Doubled with Mark, same answer tho.. There is another option for fan systems, put a cyclone on it!

LPHV = Low pressure high volume; this is not the usual abbreviation however it is normally the other way round. HVLP (High volume low pressure)

HPLV = High pressure low volume.

I agree.. :thumbs::thumbs:

That must put me in section 1 then...:funny:

Keep it on track Silver.. Means the same thing but agree we had it the wrong way around, glad you are keeping us in our toes Walter. :tongue:
