I checked out the new base from EFM and saw the way it was made, it was kinda cheap looking to me, figure I make my own.
As far any type of braceing, I think it fine and it not gonna twist, if it does, could always make another, lol

PS, I lay off now, and boss let me make the base in the shop, all the material are left over and free for me, love my job. I should be back to work 2 to 5 weeks. What eles can I make??? I know, new vent pipe for the boiler,from 16 ga black metal?? YES!

I'd make 3 or 4 ash pans with handles! :up:

Just make sure the ash door is even with the bottom plate. That is so the pans don't catch on the lip when you pull them out full of ash. And the door can't be too high or the stoker won't fit in. :)

Unless you fabricate a false floor you will be lifting the ashpan over the frame every time you pull the pan out. It may seem trivial now but it will become annoying after a while. The other option is to cut out the vertical section of the frame on the ash door side.

I second that :idea: Or make a cart with wheels that sits on rails and you could pull out the ash tubs real easy.

or like in a kodiak. there are 2 vertical pieces which act as a false floor that are a smidgen lower than the front and the pan slides on them fine. naturally you dont want the ash pan too high in there so as to restrict the air to the grate

It appears to have great compression strength, but I'm wondering about tension, albeit, it should be low.

None of the EFM bases had or has diagonal braces don't need them .
This one he made is over kill compare to factory bases

pics of frame before skin goes on tomm

You need side rails on the inside to hold the ash ring in place or you going to fill the bottom of base with ash
the ash will miss the ash tubs with out a ash ring in there .
Also you need to cut out the bottom rail in the front and make a ash door frame towards outside so you can slide ash tubs in and out with out lifting over the frame rail .

Amen to that brother. I have always overbuilt myself and my stuff from 35 years ago looks like yesterday. But, anyway, it's true that the bases aren't built that strong.

That would depend on what bases you are talking about the bases from the 40's 50's & 60's even the 70"s were built much heavier & stronger then the ones from 80's to today.
Like everything else today that is built made to throw away not to last a life time like things were in the past.
