Air Gate slide unit

[divermike]

does anyone have a good plan for an air gate slide control? when I set up my forge a few years ago, I made one, quick and dirty, but it's truly a piece of crap. I would like to make a nice one, so if you have plans, could ya shoot em to me?
Thanks.

I just scavenge them from commercial equipment at the scrap yard

You can fund some nice ones, 3" & 4" round, on the internet for about $15.

Maybe the picture will make the trip. This was made from a scrapped cylinder tube, The wall is I THINK 1/8". Chopsawed almost through and made the gate from a piece of 12 or 10 guage. The rest should be self explanatory. The blower in the pic is of course not all it should be but it worked until I got the proper one. I even hooked up a shop vac to the gate for grins.

Regardless, your source of pipe to go to the tuyere will decide the gate size. I just use 3" vent pipe and adjustable elbows.BTW the stand is made from some seamless tubing I cabbaged on to that fits nice. Adjustable height is nice.

I have seen this made from duct thickness galv. sheet metal.

You can also use a dust collector gate. (gust some googling here)

Thanks for the responses guys, looks like the first one I made was not as far off as I thought, still needs to be replaced though.
