Straight up
certainly looks do-able but maybe something that you don't want to do with a hand drill at home
I'll be making a jig like a dowelling jig., little bit of trickery and a drill press. grind the heads off and point some bolts so I can punch a template of where the holes are and maybe use an old cam to keep it all centred.
Not the kind of job to do with a mate staring at the drill....."nah back a bit, nah forward from there ....um , hang to the left.....yeah there....na na , not there..."
At nine I remember my dad looking at me with the motor from a locomotive on the model train set dismantled and saying " well , that's great , what are you going to do now"?
"Put it back together, and it'll work", I still remember the way he looked at me with a weird admiration that said " hey , you don't care either way, it's in the ride"
I've broken lots of things, some in misguided attempts to fix them when someone with the know-how could've saved me time , money and effort. Some things I've broken using them in a manner that as the old man would have said " they just weren't designed for"... either way , as I said, it's in the ride. The thing is on that ride I've learned heaps and I own that info..........Standing next to "your car" that someone else built ain't the same as standing there with a black fingernail........."yeah mate I worked my guts out in IT to pay a bunch of grease monkeys "....isn't the same as ......" yeah, I built it"
Some people do things because " that's the way everyone does it" , I'm the kind of knob-head who just has to ask why?......why can't we just do this? ....why does it have to be like that?......why pay them X when we can buy the tools to do it for that much?
Why buy a custom destroked crank for $6000 when I can get one from some bloke in Sandusky Ohio for US$65.....
But I figured you already knew all that Immortality....
The bottom line is the modification means we can still use the early cam OR the later one, it's not a "can't go back" scenario..........
