Rumford-izing a fireplace

Hello Permie Pyromaniacs!

After some measured success in building a RMH (much thanks to this forum) , I am taking on an old boxy fireplace. It never drew very well, despite having a good flue and smoke chamber, so I am thinking converting it to the Rumford dimensions (following the specs from Rumford.com). But, in typical fasion, I have no idea what I am doing! I know that Erica and Ernie mentioned that it can be done. But, I don't want to do a huge messy rebuid. My idea is to mortar up fire brick using fireclay/sharp sand and hand plastering a "throat" using metal lath and natural plaster.

But has anyone done it?

Any ideas what I should use for plaster for the "throat shape"?

Thanks for any help.

Lorne Babb : Membership has its privileges ! You're in luck, Simply Google-ing Videos of Building Rumsford Fireplaces will connect you to a mother load !

It also gets my quick rundown on selecting U-Tube videos. U-Tube Videos should be rated like a poker hand. A full house is a good hand -3 of a kind and a pair kicker !

The three of a kind is The videos with a 1)build, 2)use, and a 3)follow up video sequence -all about the project you are interested in .

Are things clear does the poster keep up on his comments answer questions and have useful communication with visitors ?

Generally a single "Look what I did'' with no follow up is a kiss-of-death!

And a couple or more videos on another subject shows the poster is proud of the work he does and is pretty handy
