Thumper

[Coyote]

So here I am in the process of my new pot still build. 15 gal keg, 3" column, Mixed copper & Stainless. 5 - 1/2" x 14" tubes in a 3 inch shotgun.

5 gallon Sankey keg for a thumper.

Now here is my dilemma, Have always wanted to watch what was happening in the thumper. Sight glass in the thumper!

Oblong Stainless Steel sight glass welded in, 3 inch wide x 12 or 14" viewing area.

Have not been able to source one yet.

Anyone able to offer helpful suggestions?

Thanks in advance.
