Get it good and clean and epoxy them. It just holds them for easy assembly and is not a structural issue.

Are the gaskets for the base sold as a kit?

So she's finally together. Still have to finish a wet return, connect the stove pipe and build a coal bin. But she should be ready to fire soon!!

=================================================================================================Hello hardcorehardcore,

Are you going to install a drop header(I hope you are)as the drop header will allow you to push dry steam to your radiators much faster as your drop header will send more dry steam faster to the radiators and your drain line to the water level in the boiler is plumbed at the end of the drop header.
You can increase the amount of dry steam by increasing the size of the pipe after the steam chest tappings and your boiler will push the dry steam out very fast and the radiators will receive the steam much faster and heat faster and the heating system will not have to work as hard.

There are lots of good pictures showing drop headers used for steam heat on the web and much information about them on the heating help forum which is free to visit and join.
After you see how the drop headers are assembled on the boilers you can easily do this with the EFM unit you have to make dry steam.

Look at his pictures above.

Hartford Loop for the win!

Maybe it is just the angle of the picture, but to me it looks like this Hartford loop is tied right into the boiler, rather than the header. This might be ok if that boiler taping is above the water line, but I do not think it is.

The Hartford Loop is tied into the drip connection 2" below NWL. Drop headers are only nessacary for modern oil and gas boilers with much smaller steam chests. This thing has a massive steam chest so there is no need for it .

Agreed on the header - but I always thought the Hardford loop tied in above the NWL. Some quick Google searches reveals that I was wrong.

Nice job on the iron work. Looks good.

I don't claim to know the details of plumbing a Hartford loop, just know if you don't have one plumbed properly.... Good luck!

For what its worth.

Your coal boiler is going to create enough steam with a drop header so that it barely runs over long periods with your demand and burn less coal. Keep in mind water expands 1,700 times when converting it into steam and the use of a large drop header will let it work that much faster to make dry steam.

If your going to install and use an Underwriters loop it has to have an 18 inch minimum height above the steam chest.

The supplied picture shows a small drop header and a return condensate line with this steam boiler.

The drop header ship has sailed. It is not required, so let's wait for the pictures of the EFM in action

The header and Hartford Loop look good to me.
