This here is a Machine that produces MASSIVE amounts of scrap virtually LAG FREE. The map here uses tekkit classic but the design works with FTB and Tekkit Lite.

So How does it work. Well basically it uses mining wells and block breakers. The mining well puts down a pipe that the block breaker breaks. The pipe is then recycled and turned into scrap boxes which are then deployed into various item even DIAMONDS.

This machine makes much less lag than a cobble generator as there is no water and lava update ext.

also the mining wells make infinite pipes so you will never run out.

Additional Notes

The map was made in Tekkit Classic but the design works in FTB and tekkit Lite.

IF the mining wells are not making pipes then make sure there not receiving a redstone pulse as that shuts them off.
