Sorry if I post too many questions yall. I do use the search function often, but if i find it fruitless I will start a new thread
This time I want to ask about flattening rocker. I cannot wrap my head around where precisely I would remove foam in the middle of a blank to create a flatter rocker, and I've seen advice against trying that anyway. So I'm resorted to using an oversized blank and shifting the outline template backward to flatten nose rocker, or forward to flatten tail rocker. Adding rocker with a planer is more straight forward.
My question is wouldn't sliding your template back and forth alter the rocker apex slightly? How are all the other amateurs flattening the bottom curve when needed?
