Blog Update

Today Ruby was here and we continued with our - of the A frame. By the end of the lesson we had the two sides for each glued together so they can be attacted properly to the fame. This lesson I also traced out reinfrocements for the top of the frame. What I have planned to do before we finish the A frame is to

1. enforce < > in with screws
2. Renforce base with pva glued wood
3. drill hole for the axel to pass through

etc...

i also broke the drill saw today and learnt to saw a few millimeters away from the cut line and then sand the rest (this has been really helpful)

I have started my timeline
