allbeit electro... that's an electric drill for you. Clever stuff. Not so though when all the innards come out as you remove the cover... doh. At one point I thought I was going to have to take the cover off the other just to see how it all goes together... but the moulded base is lugged and it can only reassemble a certain way.
So, new brushes now fitted. Good as new, and next batch scratted ready for pulping tomorrow. For a budget brand of DIY drill at £20 they do well considering the pulper alone accounts for 17.5 hrs of use with over a tonne of apples so far processed.
