welding steel base or just getting aluminium extrusion

[Boyan Silyavski]

HI, thats how to rectify something, if you mess things up and weld too fast




I am joking, just tack all in place, rectify with a mallet and then weld. But things like that happen, when i am in a hurry.

you can evaluate the option of buying chinese Hiwin type rails. last time i had great success, But the key is to buy from somewhere you know its not crap, hence directly from the manufacturer. Problem is , i said it somewhere, in China they sale linear rails at every corner shop.

I bought 10m of MGN12 from this guys and they were TOP quality, hardened rails and the carriages were good and sliding well https://es.aliexpress.com/store/grou...66f4a665DnQrsc

All you risk is eventually changing the balls of a bearing block that does not slide well. But usually it will be because is just dirty.
