I will check the exact size tonight - I know I went right off of Bobby's site and he lists 2 sizes for the 1" spud, I'm almost positive I ended up with the bigger size, 1-5/8 instead of 1-9/16. I had a really good week on Ebay a few months back and scored several Greenlee punches in useful sizes.

The small size would probably make for an easier solder job since the fit would be more snug, but I managed OK with the 1-5/8 hole.

I will confirm the size tonight, maybe we could work out a deal and I could ship it to you as long as you ship it back. You're not too far away

I used the cheap Harbor Freight punch kit with good results. The hole was a tad smaller than the diameter of my welding spud, so I just took a step bit and drilled around the edge of the hole until it fit. The manual says its 1 1/4" but it makes a bigger hole than that. I was able to make two holes with this kit in two different kegs, but Im not sure how many uses you will get from a $20 kit. http://www.harborfreight.com/knockout-punch-kit-91201.html

Harbor Freight punch sets are "Electrical Conduit Punches" & punch a hole for conduit fittings.

Here are the stated sizes and the actual hole size:

Die - Actual Hole
1/2" = 7/8"
3/4" = 1-3/32"
1" = 1-11/32"
1-1/4" = 1-11/16"

So, with that stated, be very careful.

Thanks PJ, the spud needs between 1 9/16" - 1 5/8". In other words the harbor freight ones are either too small (1-11/32") or too big ( 1-11/16")

A dremel tool would allow you to fit the coupling in place in just a few minutes.

Also Silver Solder is your friend in this adventure. Kit @ HomeDepot

No welding required.

I got mine from Amazon, I wanted to buy from Bobby, but he was out of 1/2" spuds and Amazon had both. The 1" spud fits a Camco ripple.
