In his assembly video, Ryan gave the tip about applying hairspray to the blade and inside surfaces of the grips to help facilitate placement of them onto the blade. It works great!
The drawback to this is moving or removing the grips (in the case of a damaged blade or other reasons). Once the hairspray has dried and set, it acts similarly to a contact cement. This results in the grips not being able to be moved without moving something on the inside to break the seal. I carefully used a Allen Wrench to slide it along the inner surface of the grips, but it still takes a lot of work.
If anyone has any suggestions or tips that they have tried, please add them in the comments.
