Ya’ll remember a thread I started a while back about blown burner and building a forge. Thanks to the nice knowledgeable folks and especially Stacy I’ve pretty much got it built. A VERY special THANK YOU to Stacy for sending me some much needed stuff for the forge.
Above is a view of the front of forge, the blower is mounted to the side rather than at bottom of cart. Based on Stacy’s advice the burner tube is installed so the flame is pointed toward the rear and upward a tad. This causes a swirling action of the flame to help heat the interior more evenly and the flame never directly hits the billet. That is a BIG plus!
The burner tube is 1-1/4” pipe from 90 to forge. 1” might have been better? Not sure but this seems to work pretty good. It wouldn’t be hard to change if needed.
Above is a view of the 10” pneumatic tire mounted on the forge end of the Harbor Freight cart. This is only one of Stacy’s “best” suggestions. At $4 each those tires are the best investment of all. Makes pushing cart so easy on grass.
Above is a view from blower end of cart – the tube for thermocouple is visible. With the ceramic sheath extending an inch or so inside forge the temperature is monitored nicely. The movable rack mounted in front of forge is another one of Stacy’s idea. The rack slides in for storage and slides out for use to hold the handle of billets. VERY handy. Visible is the burner tube angled toward the rear, but the angle upwards doesn't really show.
is a short video showing the flame swirling. Note the mixture is a tad rich (lots of dragon breath) to better show the swirling action of the flame. I think I got a finger over the mic causing the sound to drop out.
Above is 10 layers of 1075 & 1095 tack welded for a billet.
Above is a single brick to close off front for forging. The billet is inside heating to set weld. If you could see the billet is a pretty even heat from one end to other.
The billet is a bit more visible after playing with photo some. From the even color inside you can tell the interior is a pretty even. This is what angling the burner tube toward the rear and upwards forcing the flame to swirl around the interior.
