Try reading this.

It features a some attachments for the 8043 excavator (inc hammer),but you should be able to modify the attachment points.

thank you very much, the instructions are there?

Hi.

I built that, and the instructions should still be available here, as an .lxf file, as well as a few picks.

I have later modified it to increase the speed. I converted it to use rubber bands rather than springs, and exchanged the 24 tooth gear for a 8 tooth one. I also had to modify the "hammer mechanism" a little to ease the load on the motor. Unfortunatly I have not taken any pictures of this, and i have destroyed it... But it should be an easy mod. I makes the speed of the hammer a lot more realistic, but a lot less powerful.

You need Lego Digital Designer to open the file.

I do not fuzziona the program correctly says that I'm missing a driver! how can I do?

[Nazgarot]

Try the cad forum. They have lots of experience with this kind of things.

The mechanism is really quite simple, so you may be able to build it form the pictures...
