Down at B&Q they have a great tool. One of their precision power thingimy bobs. It's basically a rotary tool with a 140W motor. It comes with a stand, and a good quality flexi shaft on.
It's great, and it's GBP29.99 Now you can't say fairer than that. It has plenty of torque, it's a great tool for the money. Just thought someone might want to know.
My combustion chamber looks 100times better now. I just can't get decent pictures of any of it. The lighting in my office is not good enough.
