Workshop made Acetal / DELRIN Rack & Pinion

[Boyan Silyavski]

Can you really get such long screws with nuts for £100 including shipping? Otherwise I agree, ball screws are best, but at those lengths I think that screws, nuts and support bearings cost more than £100.

A bit more than i said, more or less "length in cm"=euro

Yes, that's more realistic. Around 300 pounds for the OP. But of course, it is definitely the best solution even if it is more expensive and takes more time and is also more complicated than making three delrin nuts.

Ok I think you are talking me down and the obvious (Ballscrew) is most probably the way to go.

Thanks for the tip re BST automation.

I've never ordered from Aliexpress anything to watch out for? presumably you are likely to get hit for duty on the import..

Only thing you'll pay is VAT and Shipping Admin fee which is about £12-15. Ask the seller to put low value on paper work and you'll pay minimum Vat.
