Ballscrews?

I am surprised anyone is now replying. Nine posts on the only thread and likely never to continue. Has ignored virtually all the advice offered and been impolite, too. Totally blinkered, IMO.

Best course of action is to let him get on with it without agreeing with him on anything - and hope he never makes the news for the wrong reasons. Likely take you to court for wrong advice, too, if he survived the accident waiting to happen?

NDIY totally agree with you, let him do it his own way because he knows best. Loved his earlier comment about all the toolmakers he knew who could make a simple job difficult, shows he knows b***er all about engineering. Fact of life that if you wish to lift 300kg off the ground the lift must be strong and therefore heavy enough to support the weight, I have a 300kg lifting table to move my locos and the table is heavy, I cannot pick it up, but if our friend thinks he can make one that weighs next to nothing best of luck to him, I shall not post any more on this subject.

I've been impolite to people who were the same to me.

I've investigated ALL ways this could be done and chosen the ONLY possible solution. This is NOT blinkered at all! I've spent an awful lot of hours looking at different ideas nearly all of which have been presented to me in this thread.

I've NOT ignored advice. I'm looking at ballscrews because of the far lower torque needed to start compared to other systems. I fully understand that when they get badly worn they can fail but the operating words there are badly worn.

Your frankly bonkers assumption that I would sue for getting bad advice and having an accident...WHERE DID THAT COME FROM???? You know NOTHING about me so who exactly are you to judge how I would respond or react???? If there is one thing that really angers me it's judgemental people.

I've spent my entire life being judged as stupid, retarded, a freak and a both physical and verbal punching bag. So the best advice is DON'T POST something that I might react badly to; I no longer bite my tongue and stay quiet and I am not afraid to say how I feel about something or someone. Yes, I would say it to your face.

And to Baz; I went to college and got an engineering qualification. My comment about toolmakers was something THEY SAID TO ME. I know an awful lot more about engineering than you think, been around machines since I was a child.

To others who are trying to help; 300kg is theoretical but I am not one to make something that breaks/fails. The traverser part is complete on a wooden frame the tiered section also wooden. I cannot weld but I can make lots of sawdust! Made an awful lot of swarf on this project too...

Hopper, That is interesting, thanks for the link. It is similar but mine has rise and fall and zero electronics. I have looked at inclines but there just is not the space there. I have previously built helix's but they have the disadvantage of huge drag limiting the length of train you can run (I'm aiming for scale length).

There is a product called a Nelevator but I'm trying to avoid electronics in what I'm building.

You should look deeply into that statement.

I respond in the way I've been conditioned to respond. So far in this thread one person has lodged a mild personal attack so was told how I felt. Two others have decided that it is perfectly OK to launch full on personal attacks something I have not done to them which I consider the definition of cyber bullying. I remember laying on the floor surrounded by a group of bullies using me as a football and what those on this thread did felt exactly like that to me.
