I'd simply drill that out to the next common size and sleeve it with K&S brass tubing or equivalent.

Next fix is in, new 3/4 inch wick stock for the burner tray.  I got the wick off Amazon but it actually came from Lehman's Hardware which is a pretty old store in Kidron, Ohio (Amish country).   

After cutting three slices up for the Bing' burner try, I have enough left over to last me (and the next owner) a life time!  Hopefully the donor Bing will be in tomorrow to get that sight glass cover on!

I needed to repair my pressure valve as the spring broke and the washer disintegrated.  I was really worried about the pins coming out of the popper, as they are like two legs of a cotter pin poured into the lead top. I stressed finding a acceptable spring & washer and I found what I needed on McMaster-Carr.  As luck would have it, they have a warehouse 20 miles away from my Atlanta Mid-Town apartment and was able to just just pick the parts up!  Super-duper score saving on shipping and being able to visit their warehouse (it is HUGE)!

Anyways, here is a picture of it repaired with the original spring on the far left, then the two springs and the washers.  I did end up snipping 2~3 turns off the 8969T322 spring.

• I used is the tighter spring and its part number is 8969T322  - 316 Stainless Steel Corrosion-Resistant Compression Springs 11 mm Long, 3 mm OD, 2.280 mm ID
• The washer part number is 98689A243 - 18-8 Stainless Steel Washer for M1.8 Screw Size, General Purpose, 1.98 mm ID
• I didn't use spring 2006N213 - 302 Stainless Steel Corrosion-Resistant Compression Springs 12 mm Long, 3 mm OD, 2 mm ID

Ain't that the truth! 

I am glad I got that replaced as the old washer literally broke in half when I was trying to pull it apart for the replacement parts.  Actually, I think 1/2 of it disintegrated as I couldn't really find it that half!  It would have sucked trying to get the bits out of the tank if that hand happen when I was pulling it out or if the washer popped while the tank was under pressure!

The pins are not what you would call in good shape but they should hold until it is someone else's problem.  The Stainless Steel & Washer should last much longer than 100 years (pins, doubtful).  I'll need to remember to dab some oil on it when I am done steaming it - perhaps that will slow down the rust on the pins.

well, I wasn't going to pure out a quart on it, more like a drop and work it into the spring / pins.  Though I be sure to keep that in mind and wipe any excess off :-)

You did a wonderful job with this one, Richard... It looks and runs great!     Glad I could be of some help.
