Unlike a car engine where it is drawn through a small venturi then into a larger volume manifold, Hofi has a 13 x 13 tunnel is 169 sq inches to 12 inches id or 113 sq inches. That is 67% reduction in volume. An expansion chamber in the chimney close to the fire, such as a side draft hood where the smoke is drawn in, allowed to expand, then exits out a opening equal to or about the same size as the entrance, would seem to slow the smoke down. The only advantage I can see is to drop out any heavy particulate matter at the expense of slowing the draft.

Why would it be important to expand the gases before entering the chimney?

Herman, you already found the South African Highveld Forum hosted on IForgeIron.com They post their events in their forum so check back from time to time. Take some time and look around as there is most likely some of interest to you on the site. Welcome to IForgeIron.

Philip, photos of the process many times exposes the problems you encounter. For instance, you never mentioned how deep the coke was over the fire or the style of forge you were using. Both influence the process of getting the fire started.

Philip, can you provide us with some photos of the process?

Ask a question from Finland and get answers from New York USA, China, Romania, North Wales UK, UK, Severin Romania, Michigan USA, the name plate translated from a photo in Russian by a Russian woman teaching mathematics in China, and you get suggestions on how to get the hammer working. No questions about it, IForgeIron IS a International Blacksmithing site.

Jr's (Irnsrgn) wife Cookie has been admitted to the hospital with the flu and is getting fluids and antibiotics. Prayers would be appreciated.

A 20% duty cycle would mean welding for only 2 minutes out of every 10 minutes. My question is what do you do the rest of the time? Let the machine run idle, turn it off, or what? How can you tell if you are exceeding the duty cycle and what happens if you do?

You can use a Flemish eye splice for the cable, or use a hand turned splice. A Spelter socket is a device that you place on the cable, fray the end and then pour and fill with zinc. Another way is a coupling that is crimped into place, called a fold back or mechanical splice. Two of the easiest ways is to use 3 wire rope clamps per loop (Crosby brand come to mind) with the loop of the clamp over the short end of the cable. All three clamps should be aligned identically as mentioned. The other is a wedge socket, usually used with a clamp. Depending on the size and construction of the cable dictates your choice of methods. Also different methods have a different load ratings. I have used the clamps, the wedge socket and the Spelter methods, but never could master the hand tuned splice which takes a little practice.

Congratulations !! Now with just the right training , , ,

I just saw a NEW Lincoln buzz box at Home Depot for $265. That investment and a welding class should last most folks a life time of weekend welding. Welding on not critical materials is fine if the weld breaks, but when it gets serious, so should the welding. If your outside of your area of skill and expertise, get assistance, or even pay to have it done.

Yes, I remember the ad. We used the following long 20 years before the ad ran on tv. You can take a half gallon size fruit juice tin can and the old style can opener and do much the same thing. Just make 6 *V* shaped openings on the SIDE of the top of the can. Make two on the SIDE of the bottom of the can and with a knife form a small door. Bend this to the inside of the can for safety so you don't get cut. Place some very small sticks inside the can, not many, just enough to start a fire. The heat will rise in the can and out the air holes in the SIDE of the top of the can, heating the cooking surface (the top of the can). It makes a nice little stove that is very fuel efficient. A little dab of bacon grease, some food, and your meal is ready to eat in short order.

Bryce I have placed your photos into the IForgeIron gallery. This automatically resizes them to fit the forum format. The resized photos were then the linked thumbnails were placed into your text so if the viewer clicks on the thumbnail, it enlarges the photo. Click again and it again enlarges the photo to full size. How is this done? Click here ----> Photos in the forum

Thank your friend for us. Welcome to IForgeIron.

The 55 forge is a great forge for the beginner, it is inexpensive to build, and works. You may want to look at IForgeIron > Lessons in metalworking > Blacksmithing to get ideas for an anvil, hammer, and tools. Welcome to the site.

Why not look at the inside of a water tank? It is fairly thick and about 5 feet long. Diameters I have found are 14 inch to 18 inch. As to support, just build a stand to rest the bottom section upon.

BP0422 Mounting a Vise The Blueprint shows bolts being plug welded in place. Same idea, just weld the two pieces of metal together from the back side.

Many times I have seen fabricators, welders, and even blacksmiths clean off a work table with compresses air. Just a sweeping motion with the air nozzle and the table is clean. My question is about the safety issues of this procedure. It would seem that it put a LOT of dust and debris into the air which could cause respiratory problems. It would also get sucked into air compressors, or any equipment that moves air for cooling, such as motors. Then there is the accumulation of dust on the top of light fixtures, rafters, beams, and shop equipment such as lathes, milling machines, hydraulic cylinders, moving parts etc. Any comments or suggestions on air as a cleaning tool?
