And there's me thinking that Ballscrew was another name for Leadscrew. DOH. LOL

I used threaded rods and stud connectors last time but would prefer to use the proper stuff this time.

Will have a look on EBAY and see.

Cheers

Yes it kind of is but often the Term "lead screw" is related to Acme thread which is very differant to thread type of ballscrews.

Best thing to do is drop Chai at linearmotionbearings an email with exact lengths asking for a quote with end machineing included. Also depending on how your building machine it's a good idea to get the BK/BF bearing blocks with them in same quote.

Just looking at ball screws on EBAY, what does "1204-3" mean?

I take it 12 is the diameter and 3 the pitch maybe? What's the 4?

Nearly 12=dia 04=pitch 3 Could be number of thread starts.? . . Can you post a link.?

If your wanting this screw for CNC router for wood etc then you don't want a 4mm pitch has it will be very slow. 10mm is better but you'll probably only find 16mm diameter.
