Tuesday 16 June......
Little more progress today on the cell ............. (slow progress at that

)
More drilling and tapping threads into 304 grade stainless steel

Thankfully that part of the job is over

...... looking forward to drilling into plywood and aluminium instead
Hardest part was drilling and tapping an M5 thread into the end of a 10mm stainless steel shaft ...... two 4.5mm HSS bits died in the process
Welding tomorrow hopefully ........
