Always liked drilling loads of holes in stuff, i've already drilled out the bonnet hinges and wiper motor bracket on my Escort, wanting to go bigger now ;D, cheese hole the inner door skins etc. Been looking at hole saws, don't know much about them, looking for recomendations on make, tips for use etc, are the ones on E-bay any good ?  |

I'd just go for a holesaw set like one of these to begin with www.screwfix.com/p/plumbers-holesaw-kit-6pc/11002the saw blades and arbors are industry standard so are interchangeable. you want one with bi-metalic blades with high speed steel teeth though. also when using them on metal, as the holes get bigger the speed you need needs to be slower, but you also need a drill with plenty of torque too. I ended up buying a 2 speed mains drill with a mechanical gearbox to increase the torque at slower speeds. do not get carbon steel ones like this one as they arn't suitable www.screwfix.com/p/titan-downlighter-holesaw-set-9pcs/71760 |

If it's in sheet steel that is body thickness you can't do better than Q Max punches. Far easier and neater than a bi metal saw blade.

Q Max punches are brilliant but they are quite expensive, particularly once you go above 1" in diameter. The quality of Q Max is such they last well and as such are great buys secondhand so look out on eBay. I've got maybe 20 in different sizes and tend to buy in preferance to a hole saw every time - even if a "on off" hole is needed. A 52mm might be expensive but after use it's easy resellable (standard instument gauge size ;D ) so the net cost isn't too bad as you would easilly get back a large percentage of the purchase price. I can bet however you'd hang onto it after seeing how good they are. In fact the only time I use hole saws are in wood / plastic or metal over, say, 2mm thick. |

Mmmmm drilling holes for lightness, I once did an experiment to see how useful drilling holes is and how much weight they actually save, its not a very good way to save weight, looks good, but to loose 1lb using a 25mm hole saw in a 22swg panel, you have to drill hundreds of holes, Heres a boot frame I did earlier for my cortina  |

Drilling holes is a last resort for when you've chucked everything else out, swopped everything you can for a version made in lighter material, emptied your pockets, stopped eating pies and can't get rid of weight any other way.

Exactly. I'm an overweight 18 stone so loosing 5-6 stone to get down to my ideal weight for my height is similar to throwing a cars engine away (and maybe the gearbox as well if lightweight engine)  Paul H |

1989 Peugeot 205. You know, the one that was parked in a ditch on the campsite at RRG'17... the glass is always full. but the ratio of air to water may vary. |

Some bits i attacked..........er...........sorry, re-engineered earlier  Drilled out dash frame, steering column bracket and pedal box (probably cant see the pedal box in the pic, side plates have 10mm holes drilled in them)  Wanting to carry the same theme through the car, hole saw will mainly be for the inner door tops, inner panel below the rear side windows etc. |
