  1. How large are the plant hangers?  Do you have a heated room large enough to hold the hangers, and maintain the proper temperature to set the power coating?

    Powder coating looks good until the first chip or crack in the coating.  Then moisture gets under the coating and pops it off.  There is no way to fix the resulting damage other than to remove all the power coating and apply another type coating.

    Contact your paint supplier and ask about the proper paint and proper paint viscosity for dipping.  Is that an air dry paint and how long does it take to air dry?  Will it be thin enough to get into all the small spaces?  What about the paint drips that will form on the plant hangers?

  2. Suggestions for minimum of space between the chimney and cap is 1-1/2 to 2 times the diameter of the chimney.  Draft can be improved by an inverted cone under the cap (with the 1-1/2 to 2 diameters stand off).  This helps divert the air flow out and away from the cap. 

    There is a thing called a high velocity chimney rain cap which is a larger pipe placed over the existing chimney.  I do not recall the suggested increase in diameter and length of the outside pipe.  The idea is to allow the chimney to produce draft and the outside pipe to act as a booster, sucking and introducing additional air into the draft.  By the design it keeps rain from getting inside the inner pipe.

  3. I ordered hammers directly from Hofi in Israel.  Each hammer was paid for before they left his shop.  This way he had full control of his standards on his hammers.  

    Suggest you contact him directly, and place an order for a real Hofi hammer through him.

  4. Open up the air supply to the forge.  I use 2 ea 3/8 inch bolts across a 2-1/2 inch opening, or 2 ea 1/2 inch bolts across a 3 inch opening.  I often use fines or coal dust with this set up and have no problems.

    You may need to sut slots in the forge walls in order to get the metal down into the sweet spot of the fire ball.

    Fill in the open spaces of the sides of your forge with clay.

  5. Is this what they call a half hood?

    First, open a door or window to make sure you are getting enough air INTO the shop to make up the amount of air that is going up the chimney.

    A 8 inch circle has an area of 50 square inches

    A 10 inch circle has an area of 78 square inches

    A 12 inch circle has an area of 113 square inches

    The suggested chimney size for a solid fuel forge is 10 inch and 12 inch in diameter.

    It is suggest that you use 2 ea 45 degree bends instead of a 90 degree bends so there is less restriction in the air flow in the chimney.  A straight chimney is preferred as a horizontal run can kill the draft.  

    The top of the chimney should be 4 feet above anything within 10 feet of the chimney.  Check for any air currents or eddies that may be caused by buildings, trees, or other objects that would affect the air flow around the chimney.

    As frazer said, we need photographs before we can make any suggestions.

  6. Then you use a stick welder, notice the new rod has metal showing on the end of the rod.  After using the rod, the flux forms a donut on the end of the rod.  You need to remove the donut to expose metal so you can make electrical contact again. 

    Sometimes you can break this donut by dragging the end of the rod, or by taping the end of the rod on a hard surface.
