If you're looking to step up your game in the model scenery community then you'll most certainly want to build a static grass applicator! Every one of my scenery dioramas involved the use of my home made static grass applicator.
Commercial static grass applicators are much more affordable these days and some are actually cheaper than the one I build in the video however it can be very rewarding building your own and the benefit of building one from scratch is you'll have a thorough understanding of the tool and you'll be able to adjust and modify it to suit your needs.
For example, this static grass applicator went through many different iterations before this version that is demonstrated in the video! I changed it over time to better suit my requirements one of which was being able to use it without having a mains power point available and also to keep the overall height of the unit to a minimum so it can fit into tight spots.
All of the scenes above featured in their own tutorials and all of them include the use of the home made static grass applicator shown in the tutorial in one form or another as it has changed over the years.
