making sloooow progress
1) Fixed the rails for x and y axis. i thought x axis rails will slip with gentry weight but i was wrong, rail is holding the position. only one issue here ... two of the screws close to end of the rail lost contact with the t nut inside (from very start i know that screws should be little longer) so i have to use bit more force to move gentry towards the end due to some slop in rail in the end. i will not worry about this for now but if motor can not handle this additional load, i may have to disassemble the machine or give up few inches of work area (which is fine for now)
2) gentry is moving very smoothly when i move the x axis ball screw by hand. on each turn, there is a point where i feel some friction. this resistance/friction significantly reduces when i loose screws on motor side bearing holder. George asked me to try to loose screws on the ballnut and then try to tighten bearing holder screws. will give this a shot next time i am in basement.
3) start putting in the table top. holes on one of the profile are perfect. i had to move second profile due to inaccurate cut and now holes are all messed up. I drilled few holes by hand and i guess i have to drill around 40 more holes from hand drill :-( no happy but this is the price of learning. i am not in hurry and have no deadline (actually i will like to complete the machine before i get my mill and lathe in 4-5 weeks)
old iphone gave up on me, but may be this is a sign to refresh technology and get ipad, no photos till i get ipad ... oh well. grease gun is already shipped and George also shipped one more box. from what i gathered, after George's last shipment i am still missing at least motor mounts and i think Geoge also mentioned that he is sending z axis and one more coupling, did not quite get it but i will find out in few days.
