Got the sides done. I didn't think till afterwards to check if they were square, and theyre a fair bit off. They should be relatively straight and parallel though since I did put some effort into that. |

Looking good :thumbup: do you have an extraction fan sorted? If not I have one these going spare if you want it . 240v , quiet ish and moves a fair old bit of air :dremel: Rob |

That'll suck the side walls in like the cheeks of a toothless old man :lol: |
| S. Heslop:
Yeah I would, thanks! I was planning to pilfer the bouncy castle blower from my dust extractor, but the thing is so tall it wouldn't fit under doorways. I've got a car now so I could come collect it whenevers convenient for you. |

I've forgotten everything I once knew about motors, but is there any cheap way to control their speed? Alternately I could put a baffle in the way of the airflow to slow it down but the motor might rely on Full Blast to keep cool. Wish I didn't chuck that box fan out, so I could take a look at how that controlled its speed. |
