This is more of a design question than anything, how did they make the walls of the bolt thinner on the inside without making either opening bigger? Is there a special tool that you can use on a lathe, or is it just magic?

Its not magic. Its elves!! -
Ah, but are elves not magical creatures?Originally posted by smoothice
On a serious note though, does anyone besides Tom know how this is done?Il n'y a point de sots si incommodes que ceux qui ont de l'esprit.Comment

You use an offset boring tool on a lathe. Its just that the lathes that AGD use are run by elves. :)Except for the Automag in front, its usually the man behind the equipment that counts.Comment

Ok, so it is possible to make a cut like that on a lathe, i just never saw anything like that in shop class, but those lathes were horrible, there was like one that was accurate and we weren't allowed to use it because it was for the teacher or metals 2 kids or something.Originally posted by athomasIl n'y a point de sots si incommodes que ceux qui ont de l'esprit.Comment

I'm not sure which dimension you are looking at, but think of a boring bar as a straight bar with a bit protruding from the side. You have to insert it, then lower it onto the piece and travel.
It's the same technology they use on chocolate filled cookie straws.

That's what i sort of figured, i just didn't know if they had a tool like that for the lathe. The reason i was asking is because a design i want to make sort of depends on being able to do this, simply for simplicity's sake.Originally posted by Spider-TWI'm not sure which dimension you are looking at, but think of a boring bar as a straight bar with a bit protruding from the side.

You can get all sorts of neat cutters for lathes. If you don't find the one you need, you can often make it.Except for the Automag in front, its usually the man behind the equipment that counts.Comment

It can be hard to keep boring bars straight, although a good machinist can usually compensate. That's where it goes from tech to art.
I think pneumagger had to work around inner diameter machining on his senior project in the 'Workshop' forum. He used a removable part to avoid the long reach, iirc.Comment

Thanks everyone, unfortunately i got a second opinion and my design's flaw can only be solved by electronics, which is what i wanted to stay away from. Back to the drawing board i suppose.Il n'y a point de sots si incommodes que ceux qui ont de l'esprit.Comment
