Fisher sand instead of sandblast?

Sandblasting is mainly for when they are left outside and get really bad. If you keep a water kettle on top for humidification or cook, you end up lightly sanding and repainting the top each year.

velvetfoot; You can see the fire with the fire viewing screen in place. The double door Fireplace Series idea started with customers asking for a stove for fire viewing. One of the fabricators, (Jake Jackson who lived close by) asked Bob Fisher about making his design. Bob wanted nothing to do with more door designs and refused. He soon took a ride to Jake's shop and found a Fisher adaptation. He left him finish out his quota to make Fisher's and was one of the few that parted ways peacefully. Jake became Frontier Stoves.



In 1976 Fisher added the double door model to their line.

Grandpa or Grandma? Flat top doors or arch top? There are "time period correct" and rectangular common style with chrome frame. (shown above called "Contemporary Style" - Black is "Classic") Grandma also fits Goldilocks, Teddy and full size Insert.
You CAN use a flat top door type screen on any stove, but you can't use a screen for the arched top doors on a flat top door model. The rectangular older type had latches on the screen to hold in place. The newer style for arched top doors sits on the hinges. The hinges are not spaced correctly on the flat top doors to hold the new style correctly.
New ones are not being produced. Let me know which one you're referring to and I'll give you measurements if I have them. I have the part numbers for most too. They were made by different manufacturers for Fisher, so what was used by different fabricators varied.

Here's a thread that shows the styles and what happens if you try a new style on a older stove with flat top doors;

Here's the first style with ball handles to match;

I would scrape what is loose by hand and wire brush, then paint.
Just scrape anything loose inside. No paint there.
Keep the draft cap threads and hinge pins greased and it will outlast you.
