Auckland Engineering Supplies (AES) on Beaumont St in Westhaven have a huge range of fittings and will probably have something like you need. I can probably find you a short length of 1/4" copper tube if needed and we are just above AES. PM me if you want me to have a quick look in AES tomorrow for you.

Hi guys thanks for this generosity I might give it one more go at looking today and if no luck will have to take you up on the offer. Might be able to get off work at 4.30 to have a look see. Is it just the pipe I am using cause I have tried about 7 places in total now? I am using the generic pipe that comes with the fish air pump which I think is 4mm??? Not 100% on that though. The pump I bought is the Aqua One SR-9500.

You will need to buy a hose barb to suit 6mm id hose. then use hot water to soften the hose and push it over. the hose will pop off cause of the heat made when it the smoker is alight if you use a smaller hose barb.
 
the ali tube i had was the nozzel off of an air duster gun i had lying about.

I got to say I like the concept of a cold smoke generator and the ideas in this thread.
 
Got a pig (Mrs Piggy) down in the yards that we hope to convert into bacon & ham soon.
 
 
So rainy day project this evening was to knock one of these smoke generators together.
 
I had an old aquarium pump down in the shed plus some hose for it
 
Found a piece of alloy pipe that had a hole drilled into it and a smaller diameter bit of steel pipe.  The internal diameter of the steel pipe is similar to the external diamerter of the pump hose.
 
Found a tin.
 
Drilled a hole in one side for the alloy pipe and a smaller one on the other side for the steel pipe.
 
Added a couple of holes at the bottom for the fire.
 
Hooked it all up and kicked it in the guts and suprise suprise, it works
 
 
 
The pipes are just sitting snug in their respective holes and can be adjusted.  I found that by sliding the intake pipe in further it pumped out more smoke.
 
I will let it run for an hour or two tonight and then hook it up to the smoker this week and see how it goes.

field test today and it seemed to go OK
 
Increase air flow helps and I will also increase size of hole for burn so ash falls out easier.
 
Also noted a build up of humidity in the tin.
 
May also try another tin with the pipes at the bottom, near the heat and no lid, just sawdust and see how it goes - should be less humidity.

no heat source - just doing a cold smoke of cheese, garlic, sausages (pre cooked) and eggs.
 
just a test of the smoking making unit

Got mine up and cranking last night after a bit of persuasion. I only managed about 30 mins of burn time maybe 45 but kept going out. I looked inside and the tin had so much moisture in it. It was surprising how long it lasted. I had them sitting in the hotwater cupboard for a few hours before the smoke but mayeb it was not enough. How do you guys prepare the wood chips before a smoke? The chips I am using are these ones here. Are they wrong??? http://www.trademe.co.nz/Business-farming-industry/Retail-hospitality/Kitchen-equipment-supplies/Other/auction-359742563.htm

i have never had a problem with my wood chips going out. my wood chips in the movie clips i made had been sitting for 2 or 3 years in my garage that is as damp as a wet winter.

maybe your venturi tube is to long or to short.  can you post up pics of your setup.

I will have to get them up in a few days as my camera has sh&t itsself but will do as soon as I can. Yeah I didn't think the wood chips would be a problem. What about the moisture in the tin during burning? It coated all the walls and was driping off the lip when I took it off.

Well My Mate and I made a new smoker and failed miserably.
 
I thinj i was trying to be to greedy and use a too bigger tube to hold the wood chips. I grabbed a piece of 100mm dia stainless and found that the chips will smoulder and a small amount of smoke will come out, but i think the excess chips between the smouldering ones and the venturi was cutting down the air flow to much.
 
I will get some 63mm or 2 1/2 inch pipe to try next.
 
Apart from that the one we made yesterday definately looked the part hahaha. will try and get some photo's up when i get home.

I have managed to get a new tin for smoking so instead of giving you pics of my epic fail attempt I might put up pics or dimensions of the new tin to see what your thoughts are on what the best design will be. If you have a similar sized tin or ideas then measurements would be great thanks cause i'm not sure if I will be able to get a new tin anytime soon and I am really want to get this up and going. Pics or dimensions to follow later tonightSmile
