New Larger Hopper for My LL

Thinking of building a hopper with aluminum. Will aluminum stand up to coal or will it corrode quickly?

Aluminum will last forever assuming it doesn't wear out. That's not a concern unless you're unless you intend on burning a couple hundred thousand ton.

Instead of going through all that work, just build an extension on the top of the hopper. For every 1 inch of height your going to gain about 7-10 lbs of coal. Make sure you place a support under the hopper so the stove doesn't tip.

Putting on a larger hopper is fine and dandy but of what use is it unless you also have a larger ash pan?

Jer,
The reason for my new hopper is not so much to increase capacity, but more to make all the coal fall towards the feed paddles. I find that with my 10-14 hour work days I often come home and the stove is out or almost out, but there's still a lot of coal left in the hopper. The new hopper will have angled sides and back. With the jacket I made the stove is now 45" wide so my hopper will be 45" x 14". The capacity will be about the same.
