Current Club Drill
As I understand it the club has an old 24V hammer drill. Anyone know where this is and what state it's in?
Similar question goes for battery packs for this drill - do we want to use some of the GP Batteries cells to make new ones?
New Drills
Makita are very kindly giving us 2 new BHR180 rotary hammer drills. These use 18V battery packs: Some possible things to consider:
- Do we want to mod them so battery packs aren't attached to the drill but can stay in a tacklesack?
- We need to make some padded tacklesacks for transporting them underground.
- We can make spare battery packs using some cells from gp batteries.
- Charging: am I right in thinking solar panels at top camp can only charge 12V or 24V? We can either try to make a transforer, bring a mains adaptor up, or take battery packs down to basecamp for charging. Thoughts?
Do we need some new drill bits?
