London Power 3 channels amplifier project

[Vostre Roy]

Well, ran into a small issue, will delay the project a bit ahah

Turns out that the Hammond's Steel chassis is one hell of a bitch to drill, everything was going well until I had to ream the tubes holes. I've got a step bit that I've used in past project and a Mastercraft (cheap) press drill that I'm using for the first time. Well, since the holes has to be big enough for the tubes to pass through the chassis (as opposed to my previous projects where just the socket would pop out) and that the chassis is much stronger than the aluminium ones I've used in the past, I can't do a clean job. The power tubes holes has to be as big as my step bit's biggest size and the drill keep on jamming (did I mention that I'm using a cheap press drill).

So I'll either have to find someone locally who can save the chassis I'm using or I'm ordering an aluminium one so I can at least get something done. Unless someone has some ingenious way to deal with that issue
