I just recently started to use this kind of bases for fire teams. I find them to be visually more appealing than the usual single based models. Especially with firing machine gun teams it looks more convincing to me and allows you to put the figures in scene. Another plus in my eyes is it's easier to handle while still allowing for easy casualty removal.
To make your own sabot bases you'll need:
- Footfall sound insulation (In German it's called polystyrol)
- Round lasercut or plastic bases the size you want the final sabot base to be
- Hobbyknife
- Marker
- Proxxon (or similar) Hot Wire Cutter
- 21mm Hollow punch
- 20mm Washers
- self adhering magnetic bases
- Fast curing PVA
- Old brush
