Just finished my Lead 1515 and wanted to share what I've learned from it...... Watch the assembly video before you start opening packages. DONT OVERTIGHTEN fasteners, after you strip a few you'll know what i mean. Really snug seems to work. Adjust concentric nuts exactly as advised. When working with the small screws make sure you are over a table putting things together. Nothing like looking for a tiny black metric screw underneath a table in the garage against a dark floor...you know what i mean. Refer to the forum when in doubt, tons of helpful folks here.I had every question answered quickly. Customer service is top notch with Openbuilds as i was looking at a competitors machine till I read how bad there customer service is reported to be. That changed my mind as support is important especially being new to this. So far I'm very happy with my choice. P.S Openbuilds it would be nice if you threw in a few extra screws, T nuts in the package builds because my garage floor hates me.
