I agree, it sounds like a lot of work and i don’t think it’s needed. Last year was my 1st year with a wheelhouse but here’s what worked well for me:
Lower house half way… if wanted. Can drill with house up too if ice isn’t too thick. House will move forward some when dropping so drill holes towards front of hole opening if house is higher. Leave slush piled up.
Drop house on ice chip piles.
Insert hole sleeves.
Use biggest Menards paint mixer on cordless drill to suck ice chips down the hole.
This works amazingly well for something like $7. Really don’t have to scoop holes out after this. No big slush bucket. No chips on the floor. No scooping a bunch of chips into a bucket and making trips to dump them out. Seals well around the holes. I don’t bother banking the house if just out for a few hours, but you could if you had other snow on the lake. I’d just use a shovel and shovel some snow up against the house.
Most of the time the very few if any chips remaining in the hole would melt after a bit.
