I'm wondering what the condition was of your stove such that you determined you needed to take it apart...what were the "symptoms" so to speak?
Ray has not posted for almost five years, according to his profile. I do not know if he still reads posts. However, in the original post in this thread, he wrote: "It is time to disassemble it and remortar it, as it is getting harder to control the air to the firebox."
That has been my experience too. The controls had to be tightened down more than previously to keep the stove from overheating. My Waterford Stanley is from some time pre-1992. I am unable to be more specific.
As for the smoking you mention, scrape the top of the oven and the flue-gas passage on the right side of the oven. Use a
radiator brush down through the bonnet. Then scrape everything out from underneath the oven through the cleanout port. That all should be done about once a month -- so you are long overdue. Clean the chimney. If that does not take care of the smoking, re-cementing your stove may help. Take a look at what Ray did -- his is a good tutorial.
I re-cemented my Stanley a couple years ago, and the cement fell out so I had to do it over again. I am pretty sure I used Rutland's cement that first time, so when I re-re-cemented it this fall, I used Hercules brand (which is an Oatey product). Of course, the jury is still out, but my stove has been drawing very well since I first lit it this season.
the door pulls aren't securing on the stove.
The door latches can be disassembled and (carefully) ground to tighten their grip. Probably your hinges are worn, too. If the hinge pins can be changed (unlikely, if I understand the age of your stove) that would be a good plan. If pins are
not replaceable, replace the door gaskets and hope for the best. There is at least one way to shim door gaskets, but I have not tried it.
I wish you the best. The Stanley is a good stove. If yours is not too worn out, it should serve you well.
