Could not fully assembly item.  Need to get additional tools to from my shop to modify product.  Two parts were incorrectly constructed so that the screws would not connect to the other  part.  One tube had the hole at a different angle than the other tube so the screw would not pass through the hole.   either have to drill or file the hole to fit the screw.  Not yet done.   I think I can finish the construction, but not certain.
