Attaching blower to tuyeer

[jkeller]

This should be a simple one for everyone to answer...

I bought a small forge, but the tuyeer is not connected to the blower. What should I use to connect the two?

Many folks will use the flexible metal pipe you get for venting a clothes dryer. It's mostly 4" diameter, but you can crimp and fold the ends to fit smaller openings. This is what I am currently using. It's ugly, but it works. You will have to improvise to get a tight fit.

For a permanent solution, I am planning to weld up a short section of pipe to a plate to fit the bolt pattern of my tuyere. I hope to weld a necked-down section to fit the blower, and possibly and air-gate in the middle.

Also consider that once your metal pipe is far enough from the fire that the heat doesn't travel, you can adapt to PVC if you need some inexpensive versatility.

Anything to get the air to the fire.

Clothes dryer vent, worm drive hose clamps and duct tape. Last week my vent blew off of my fan. Too much back pressure I guess. I wondered if I made a mistake with the duct tape etc, but it only took 10 minutes to duct tape it all back together and it is now working fine.

In the past, when the situation required a more heavy duty solution, I have had good luck using flexible exhaust piping (for automobiles) and band clamps. They are heavy enough to take quite a bit of heat, come in a variety of diameters, and are relatively easy to locate in auto parts stores, muffler shoppes, and junkyards (the flex pipe normally conects the motor to the exhaust system on most small cars). Hope this helps!!

Scrap driveshaft tube measures on the O.D., so 3 inch flex exhaust piping fits over 3 inch driveshaft tube real nice.

I also use automotive pre heater hose to move the air from the squirrel cage blower to the piping under the forge. I make the connection with duct tape, it holds up just fine in my experience.

I also use aluminum dryer vent and I created a reducer out of 14inch aluminum flashing to neck down into my tueyer. This allows a snug friction fit that I can pull with minimal effort when I hook up my electric blower. It took about 10 minutes to roll it and pop rivet it.

Thanks

Here is what I did. I got the tap at a junk store for $2 and found the pipe in the scrap pile. Air is supplied with an old vacuum set to blow.

Note the improved ash dump, much easier, thanks to Irnsrgn.

My fire pot is so big because I burn wood. Coal fire pots are much smaller. the fuel you are going to use determine the size of the fire pot.

My local hardware has 3 inch aluminum flex dryer vent hose as well as the 4 inch. I am currently using the 3 inch. It was a little tight fitting over the blower. This works very well but it is ugly and does not seem very durable. I think I will be checking out the auto parts flex exhaust pipe option soon.

Puppet,
Using a tap to regulate air flow has to be an original idea. Good thinking! I have some 2-3-4" brass butterfly valves that probably will work a little easier. Thanks.
