Hi, and a question.

[lonlaz]

Hey, I've been lurking here for quite a while and have learned a lot so far. There's tons I don't know, but I'm hoping to pick up the knowledge as I go along.

Right now I'm collecting the parts, and drawing up plans. I want to build a small engraver to get my feet wet here, it'll be slow going since I have a limited budget and I'll need to pick up some tools along the way. I've been putting together the X table on sketch up.

The table is 4"x4", but the travel is only around 3.5" supported by a NHK RSR-W. I'm trying to make the plan so I can put it together with what I have available, mostly woodworking tools. I'll have to pick up some other tools to accurately drill the holes I need.

So, my question is.. do I need a bearing block to support the motor end of the 3/8 acme screw? I was thinking since the linear bearing was supporting most of the load, I could skip, let me know what you think.. also please point out anything else you see is a problem.

Thanks!
