Thread: is this a good enough dusty for a lathe

just wondering because within the next month or so i will get a dusty, and i wanted to know if this is suitabled to be hooked up to my mc900 and gmc bandsaw.

1200cfm seems reasonably good.

also, is it advisable to buy a attatchment to fit to the lathe, or is it not neccesarry? and if so, can someone provide a link to the one that is best ( preferably not home made )

one other thing:
carbatec or hare and forbes???????????????? not fussed about saving $20 for better quality if it is applicable

cheers

btw, any thoughts are welcome and if any one owns one of the two...telll me how they go.

Stirlo, the CT one looks the same as the Leda machine that I use. It is more than satisfactory for capturing the dust but don't expect it to get all the shavings.

CT also sell a 'big gulp' attachment on a stand that you can position behind the lathe to pick up the dust.

does any body have a "big gulp", and is it worth the $30.

btw thanx groggy

They are all exactly the same......all come from same mass producing factory in PROC and just get re-badged and marketed accordingly.
I did a "suction" (sorry i'm no engineer ) test with a Manometer of a "Leda" extractor and a H&F unit....both the same....exact same build too....
Go for the best price, or maybe the H&F unit because it has cloth bag on the bottom, more durable.

I have the H&F unit

Hmm, add 1 part imagination to 1 part determination, mix with some heavy cardboard and.....

it equals a 'big gulp'. now that you mention it, it doesn't look all that hard to copy, cept for the bit that would fit onto the hose

G'day Stirlo

Don't think there is much difference between the two as others have said. I would consider getting the one from CT so you could get this nozzle with stand as well

From my experiences I think you will find that it is virtually impossible to catch all the shaving, so I just put the nozzle next to where I am turning and sanding to catch the fine stuff that we shouldn't be breathing in

My experience with both single bag and double bag dust collectors is that the single bag units don't offer near enough suction to do a reasonable job. Also use as little flex hose as possible - the more you use the less efficient the collector will be. And use the largest diameter pipe you can also, I don't think 4" pipe is good enough for trying to pull dust and shavings from a lathe. If you go with the single bag collector pipe diameter and flex hose limits will be especially important.

stirlo, my recommendation for a young lad like yourself is to do an experiment and make your own dusty, really its not that hard. i made mine using an old washing machine motor. i just designed an impellor to place on the unit instead of the pulley, i cut the pieces out of sheet aluminium and pop rivetted them together. i made a cyclone unit to separate the majority of the dust before it enters the impellor and it gets, dare i say it, ALL the dust from the planer-thicknesser and the jointer. this unit would suck a golf ball through a garden hose. i might even marry it.

The CT one is $10 cheaper until the end of this month.
Seems like a good buy.
I am also in the market for a dusty.

G'day Stirlo,
Good to see that you're getting a dusty for the lathe & bandsaw. I wouldn't be trying to collect the shavings as such. What you do need to collect is the dust - that's what causes the grief with our health.
I made my own " Big Gulp" collector out of MDF & turned the hose spigot out of pinus crapiata & glued & screwed it to the back of the collector. I'll take a couple of piccies & post tomorrow morning for you if you like. The collector wasn't very hard to make, even for me. If some other fool can do it, then so can I!
Regards,
Barry.

How about some pictures of yer Thuper Thucker then? he asked with great interest.

Hi all,
I would first like to say I am not out to burst any one's bubble, but don't be fooled into thinking a dust extractor is going to protect you from the nasty stuff. I am not going to get into a big discussion on filter size as this has already been done on the forum but for those of you don't know.... The human eye cannot see particles below 100 microns ( this is one hundredth of a mm..... I think) yet particles as small as .4 of a micron are considered carcinogenic. Which is why HEPA filters go down to .3. The bags that come standard on "dust extractors" are usually 30 microns which is why alot of people in the know call them "chip collectors"
What am I getting at, you may ask?
Always wear a mask!!!!! Even a good quality disposable P1 or P2 mask that carries the AS/NZS approval number is acceptable. Wear it whether you're turning, sanding or just sweeping the floor, as I said the stuff you can't see is what can ruin your life!

p.s. If any of the above is false please chime in as I think we should know as much about this subject as possible, especially those just starting out.

hi guys, thanx for the suggetions and tips.

making my own dusty is out of the question because mainly i wouldt trust myself to make a good enough one.

making my own big gulp seems the way to go.

i already know that a dc ( specially a cheapo) wont get most of the chips, but the dust is wat i want it for.

josh, i always wear a cheap little mask and glasses and will continue to even with the dusty. and will upgrade to a respirter at a later date.

barry, i would like to see your photos.

benchdog can we see photos of your home made one

toolin i'm afraid i wont be able to afford a two bag one so a bag will have to do unfortunately. thanx for the tip about the pipe though. is 1-1.5 m too much hose for a 4" out let? and is the 4" too small if you have a big gulp?

cheers

A few things to remember when setting up your DC:

It was said earlier that DCs let a lot of fine dust escape through their filter bags, it's especially so when they're starting up. If it's possible have it outside or at least as far away from your your working area as possible.

The bigger the diameter of pipe the more air flow it will carry. A 6" smooth wall pipe will carry more than double the air of a 4" flex hose.

Use smooth wall pipe because the turbulence created by flex hose will reduce air flow significantly. Use as little flex hose as possible. Short lengths to hook the pipe to the machine is all you should be using.

Air, like water wants to flow in a straight line. Minimize the number of bends needed and use 45 degree bends instead of 90s if possible. Flex hose doesn't lay in a straight line therefore it will reduce air flow even more.
