Broken piece attaching flue collar

[Snipedangles]

I bought an old VC Resolute. The bolts in the back to the flue collar and extension were corroded or cemented on. Could not apply any torque without stripping the head. I ended up having to drill out, but the screw forced the bit off a straight path. I tapped in new threads; due to the odd path, it left little room to edge of stove, and a piece broke off. I can get the flue collar tight, but it still worries me. Is this safe?

That looks pretty tenuous. It's going to need reinforcement.

Thank you for the reply. I was thinking of putting a nut/washer and cementing. Bad idea?

Bumped into a Resolute II for $500. Considering I have to buy a flue collar extension ($138) and the broken piece I am contemplating buying that. Though I like the Resolute I look (top griddle)

Would using a nut, washer, and cementing constitute as good reinforcement?

I bought another one.
