I noticed a risk of breaking the blade bands on 3 or 4 blade broadheads if the arrow is pushed into the foam. If you don't push then the arrow isn't held securely.
I pulled the original insert out and traced it on a piece of firm foam. "Minicel" 3 lb density was used but any firm closed-cell foam is fine.
I used a bandsaw to cut out the blank. On a small project like this a snap-blade utility knife would work well also.
I wanted to create pockets to surround the blade tips. Foam cuts easily with a thin brass tube and in this case I discovered a plastic highlighter body did fine since I didn't have 3/4" brass.
I cut about 3/4" deep by rotating the tube back & forth while pushing straight down. Then a plunge cut from the side with the snap-blade knife separated the slug from the block.
I then used a sharp awl to give the broadhead tip a hole to follow.
I'm happy with how my scraps turned into something useful.
