Postby cacticlayton » Mon Jul 15, 2013 5:46 am

hey guys I need a little help with this. The hole that I drilled for a 2" pipe connection came out to big and I little off center. So I'm trying to figure out where to go from here. Another concern is that I worry that the lid wont be able to support much weight. Any ideas will be helpful, Ive had this thing just sitting around for awhile now.

I was shooting for 2", but I ground it out to much. So now I plan to go 3" but my main concern is how to strengthen the lid so that it will hold the weight of a column.

Order in a 3" easy flange and you need a leveled table or bench... the set the lid on the bench...
Place the ezflange on the lid centered and level it in place in two directions @90 degrees to each other... then solder it securely... then remove the excess material from inside the ez flange... get a 3 to 2 reducer, a gasket and clamp and your good to go with a column at 2 or 3 inches..

If you are concerned about the strength of the lid....... just split some scrap copper pipe and solder in a few ribs inside the lid... that should stiffen her right up



Oh by the way, that looks like it would also make a fine thumper also

thats what I was thinkin too FS, but when I set a ferrule on it I was worried about the strength of it. I guess it will just have it's limits. I will solder on a ferrule tonight and see what happens. And if its not strong enough I will puts some ribs in it. Great ideas guys, I'll keep you posted.

As long as the table is level your good to go... :text-goodpost:

have fun sir.... and clean the heck out of it before you solder ferrule and copper both... :mrgreen:


with the conical shape i just don't see it being weak? but if you think so i would solder the ribs in first maybe in case it pulls or warps a bit .... :confusion-confused:

I think it will be fine as is, now ive just got to figure out what kind of column I want to put on top of it. Since its only a 6 gallon pot im thinking it will be a stove top pot still but we will see.

You don't have to use a ferrule directly, you can do it with a flared pipe end or a cylinder .

This was actually a cylinder made from sheet, but the principle is the same with a tube. It was going to look like this at first, but I turned it into a water sealed pot in the end.
