Hi Everyone,

Here is a guy called Steve Bedair that built his own wood chipper:

Pretty impressive stuff... However it may be a lot simpler and cheaper to buy one like this:

Here is a youtube video of the Titan in action:

That looks a very impressive machine to me and buying straight from the manufacturer means the spare parts will be easy and cheap to source. 14HP should also give you more than enough power to handle substantial branches. The chip output in the video is very impressive and the final chip size looks small enough that very little, if any, processing will be required. This could save you the trouble and expense of buying a dedicated wood pellet making machine which costs thousands of £!

You are quite the progressive Ape!
An excellent compilation of info you have brought here for the experimenter![in this case me]

This Gasification is very cool, We recently had some Tornados come thru my part of the USA!,There are quite literaly Trailer Cars of shreddings to be had for the taking?

The power of Nature is absolutely Jaw Dropping ............

I've been Very busy trying to make ends meet lately,perhaps making "Gas" will help towards that end!
Thanks for all you do ............

Hi Chet,

If you liked the other stuff then I think your going to love this! 

I cannot afford an EGU and I don't want all the kiddies playing without me so I went back to the drawing board and came up with the Poor Man's Exhaust Gasifier.

This is made from common automobile exhaust parts and all clamps together, no welding!

As you can see exactly the same principles apply as used in the Everyman Gasifier but this is a much cheaper option.

Here is a major UK exhaust manufacturer that has every part you need available via ebay. Call them or email them to specify the exact dimensions you need for each component:

I have put pictures below of every component listed on the Gasifier drawing.

All of the joints are made by tightly fitting sleeve components and clamps. Use fire sealant on assembly for an airtight seal. This will dry hard and form the custom gasket.

The Gasifier is supported by a frame made from stainless steel box tubing:

This can be bolted together so you do not need to buy a welder, but of course you can weld it if you want to.

Avoid these hose clamps if you can as they have a mild steel bolt that will rust out quickly:

Use these instead they are fully stainless and heavy duty:

Here is an interesting thread on clamps:

http://101club.org/forums/viewtopic.php?t=4750

Also do not use galvanised clamps as they will react with the particular sealant mentioned in this thread and create hydrogen which is bad in an environment with an operating temperature above that of hydrogens auto ignition temperature.

The bottom of the Gasifier is sealed by simply pushing it down into a square block of modelling clay and then bolting it to the frame with U bolts. To empty the ash simply unbolt the gasifier and lift it up, kick the clay out of the way and put down a new piece, then bolt it back to the frame:

Obviously the EGU's are better quality with thread locking and sealing but beggars cannot be choosers. You can add a stainless steel threaded rod down through the fire tube to shake the basket as with the EGU Mk1 if you want too for static application.

Exhausts are normally in the range 1.75” to 3” so this is why we have a 3” fuel hopper. Interestingly MIJ Exhausts advertise up to 6” diameter tube for making custom flues for wood burners, it's just a pity they do not make a 3” to 6” adaptor sleeve clamp Maybe they will make them if there is enough demand... and it sure will be handy to have a 6” wide fuel hopper!)

So what do you all think ? Simple and cheap enough ??

Hi Everyone,

I have worked all night on this and I am shattered so the brain is not working quite so well, and 15 coffee's has not helped much with the headache.

There is another option for the fire tube:

http://cgi.ebay.co.uk/Universal-8-Exhaust-Silencer-Box-3-Inlet-76-4mm-/280614588666?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4155eed0fa

This is the clamp on type with a 3" inlet so it will be compatible with the joining sleeve. What you need to do is use a hacksaw to cut the large end off, then you need to reach your arm right down inside with a dremel and use a cutting disc to remove the perforated inner tube that creates the silencing effect. You also might be able to cut the tube from the 3" inlet end which will be a lot safer! Be sensible! 

This will give you a large diameter fire tube that in this example can be 40" tall. The cutting disc might bite on the holes in the perforated tube so be...

EXTREMELY CAREFUL NOT TO CUT YOUR FINGERS OFF! I am not joking!

However what you will now have is a large fuel hopper

Hi Everyone,

Just a quick note here to let you know that you can mix and match between the EGU and the PMEG parts.

If you have gone the route of threaded pipe fittings then you have probably chosen a 2" NPS Fire Tube. Barrel Nipples of 2" NPS are cut from S40S Seamless Pipe and therefore the OD of the pipe is 2.375" or 60.33mm as we can see here:

http://www.zx55.com/shopexd.asp?id=5053

You could then use a Custom Made Exhaust Pipe Adapter Connector Sleeve Joiner:

http://cgi.ebay.co.uk/Exhaust-Adapter-Connector-Sleeve-Joiner-Clamp-Clamps-/220783509427?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3367b8ffb3

Just tell them that you want to join two pipes with OD of 60mm and 76mm and it should fit really nice.

This will allow you to use an exhaust back box silencer as a fuel hopper, once modded as I have described, and this will greatly increase the fuel capacity of your EGU for relatively little money. You could also visit some scrap yards looking for cars and trucks that have stainless exhaust systems and just cut the pipe and take the silencer home. Lorries for example often have massive stainless silencers because they last for the life of the vehicle and do not need replacing every few years as the mild steel ones do. Its about the $ remember

The 76mm dimension is because the back box I linked too has a 3" inlet tube for connection, if you use a different exhaust then the inlet OD might be different so check before you order the sleeve.

This will give you a very high quality unit
