So this week I fixed the head wiggling! I had to sacrifice the length of the handle and I taped the top of the paper towel roll to the top of the hammer. I also made the ends decently good looking now but it still doesn’t look perfect. That is what I have done to build my Mjölnir.
Thanks for adding the photo to include evidence. Are you okay with sacrificing the handle length or is this something you hope to adapt in a later stage?
I think that it is ok for now that the handle is shorter. When I am about done and working specifically on the handle I can see if making it longer will be necessary.
