Follow the instructions on the JABOD or the Side Blast 55 Forge. 

I used the Side Blast 55 Forge for over a year and could not see any damage to the sch 40 pipe used as an air inlet. This was HEAVY use much of the time at welding heat.

The original 55 forge (bottom blast) did erode the end of the air pipe after a couple of years. That pipe was standard, used and thrown into the dumpster, auto exhaust pipe . Even then the damage was only about 1 inch erosion to the thin wall tubing, and fixed by drilling a new hole in the auto exhaust pipe to hold the grate. Elapsed time was how ever ling it takes to drill a 1/4 inch hole. 

mine is 2 inch and don't know how long it is 

What size, schedule pipe, and pipe length were called for in the JOBD building instructions?

What size, schedule pipe, and pipe length were called for in the Side Blast 55 Forge building instructions?

i don't remember. 

i used that pipe for this forge

Then I suppose it would be time to actually read the instructions on how to build a BOX of Dirt Forge or the Side Blast 55 Forge. This is a critical component in building your mower deck forge.

 

Hint A site search for JABOD has 167 results. I did not search for the 55 Forge (side blast version).

i watched the video on Purgatory iron works. forges pt 3 or 4 

And what was the pipe size, pipe schedule, and pipe length that he recommended?

i really don't remember its been a while since i messed with it 

i got one good heat with the rebar 

You are typing, I am actually viewing the forge #3 which is 13 minutes long looking for the recommendations that were made. 

i think he was explaining the process of it i know he gave specs for the brake rotor forge.

Now actually viewing the forge #4 which is 7 minutes long looking for the recommendations that were made. 

also take a look at #5

Now actually viewing the forge #5 (Language alert) which is 13+ minutes long looking for the recommendations that were made. 

 

I have watched his videos and located the answers to MY questions as to the size pipe, schedule of the pipe, and length of the pipe that he suggests. Yes it was just that easy. 

i got the forge ready to go but my brother being on his side of the family and don't get side tracked. i have to pick him up Friday which puts back everything by a day and if the coal doesn't come when i call well were back to throwing wood in the barrel and making charcoal.

When you got the forge ready, what size air pipe did you use? What schedule or wall thickness, and what length pipe?  Was that what was recommended in the videos?

2 inch and I welded to fit no leaks water quench test 

watch the video I will post probably Saturday upload a link and close the thread 

This is where things start to get confusing. We were talking about the JABOD and the side blast 55 forge.  My questions as to pipe size, schedule, and length, were in reference to those forges.

Your photos and current project is a bottom blast lawn mower deck forge with a brake rotor.  Please specify which forge you got ready, JABOD or the bottom blast lawn mower deck forge with a brake rotor. 

By my count, we have gone from 2 forges using coal (understood but not specified) to 3 forges and 2 types of fuels, and then to making charcoal from wood. 

 

We must stay on ONLY ONE topic at a time. Please specify which forge you want to discuss AND what fuel is being used for that forge.

the rotor forge and gone from charcoal to coal

plus the variables 

To be specific, is the rotor forge you mention the same as the  bottom blast lawn mower deck forge with a brake rotor?

Do you know if the bottom blast lawn mower deck forge with a brake rotor can be used equally well with either wood charcoal or coal as fuels?  Or is there some sort of modifications involved when changing fuels? 

well I've been using hot coals that come out of the fire with air blast but the rotor should hold up 

You did not answer my question.  Is the rotor forge you mention the same as the  bottom blast lawn mower deck forge with a brake rotor in your photos?

as purgatory iron works

if yes then yes 

its close but not exact 

 

The answer should be 

1) Yes, you wish to discuss the  bottom blast lawn mower deck forge with a brake rotor in your photos.

2) No, you wish to discuss another type or style forge. 

 

Please answer by indicating the number of your choice. Once this is established, we can proceed. 

yes I wish to discus the bottom blast brake rotor forge that I just posted pics of
