That’s right it’s soft. That’s why it can be cast because of the lower melting temperature.
I should have known better back when I cast aluminum in Jr. High. But that's been so long ago I forgot Live and learn. Should not be so noticeable with paint on it and fire going. Jeff

It could be worth your while to check the prices at a local company that does powder-coating. Sometimes they just want to recoup a little of the cost of keeping the oven going and don't charge a lot.

Your project is fun to watch, and I look forward to seeing the finished product. On the contrary, you are living and learning. If only I can get off my butt to finish my to-do list, that would be great!

GeHmTS,
If you only could see how long my list is. I repeat do not buy a fixer upper when your older you will regret it. lol I still have the master bathroom to do and the living room the stove is going in and then the big money the kitchen. But This spring the first thing is a shed and a work bench I'm sick of storing all my yard tools in the garage and work stuff. And the worse part is when I get ready to start a project something happens. Jeff

Just for motivation...I purchased a 52i for a steal last October,sat in the guy’s garage all summer and rusted quite a bit as you can see..but finished product ...looks amazing and heats just as well

Stove bright satin black..on the frame I used rustoleum bbq paint which has a rust preventative in it
How many cans of the stove bright satin black did you use? Thanks Jeff

Rust is mainly caused by condensation of invisible water layer on the metal surface. This condensation may be due to a difference in temperature from a hot to a cold surface, particularly when the cold surface drops below the dew point. For example, the rust you see on car exhaust is an example of this effect. There are corrosion resistance oils on the market which are hydrophobic that do work. Paintings the metal is another solutions.
Do you have an example of which oils? Like PB blast? Would I spray the frame
Of the stove? Would I spray also inside the stove (heat exchanger, etc)

Eeps24 I only sprayed bolts and nuts with PB Blast and Kroil but still nuts and bolts broke off :( I spent a lot of time getting the bolts and nuts out in hard to reach places now I'm reluctant to try and remove unless I really need to. I would not be spraying oil inside the stove unless your putting it on nut and bolts you want to remove. Jeff

I'm on rain delay from sandblasting and let me tell you about Rust (you all already told me) that stuff sucks it's already starting to form again on the parts I sandblasted so I went to the store and got some paint as soon as I can blast and paint I will I hope today if it clears up. Jeff

There are chemicals you can wipe on,to prevent the light surface rust,but,not all are compatible with all paints and primers.Any metal that has been "blasted",any type of media,should be washed with mild soap and water.A air hose to dry parts works well.Then immediately spray on some primer.Most people will do sections at a time.And,yes,you can get the primer wet,as if you are working on a large panel,and blasting in sections.

Well the weather cooperated with me today for the most part. I have all of it done but the bottom pan and under that so not much more left to do and have it primed up. :)

I have a few questions is there polarity on any of the motors auger/distribution/combustion motor?? My vacuum line runs about 6-8" then goes into the side metal box is that where it stops? And if anyone has a clear Image or directions of theHarman air bypass kit that would help. Bob did you find it? How many cans of the stove bright satin black you think it will take?Thanks Jeff

Impressive! What a transformation, huh?
Thanks :) and yes it turned out great so far. Now the bottom pan and under the bottom pan. Will post pics when that's done. Jeff

Looks good.The first attempt was drilling the auger tube,which is now obsolete,as they found the bypass tube works much better.Will leave you 2 links,if they allow it. https://www.hearth.com/talk/threads/harman-accentra-gummy-stove-syndrome-solution.45548/ https://hearth.com/forums/threads/who-has-the-gummy-fix-on-their-harman-see-pic-how-do-u-like-it.20022/
Bob,
The first link shows a hole in the auger tube?? Is that where I drill?? The second link is a dead link :(. Thanks Jeff

Now do not drill the auger,that was Harmans first attempt,then they found out the hose kit works much better.This site will not allow the link from the other pellet forum site,I will try and copy instructions for the kit,and put here.
