I am wanting to start to try to repair my broken side winder.  Where should I post my questions on what may be wrong and how to start?

https://www.cousinsuk.com/product/horia-jewelling-tool https://www.cousinsuk.com/product/assortment-24-pump-pushers-24-anvils

Would the chinese one not be sufficient though? The tool and full set of 24 stakes and puches for less than £300 The Horia tool and 24 piece set is £1278 on Cousins

In this case the difference is not 1:10. A Seitz before stakes and punches is £290 + VAT https://www.cousinsuk.com/product/seitz-jewelling-tool-with-spindle Maybe you can get the needed one as you go. Or bite the bullet for the complete set at £875 + VAT. And I'm sure there are deals on Ebay if patient.

I would like a jeweling tool to practice correcting end shakes and also to install jewels. The Horia tool with a set of pushers/anvils is out of my budget at the moment. I noticed a Chinese version https://www.aliexpress.com/item/4000261581571.html?spm=a2g0o.detail.1000013.1.5ee15a59YGNywJ&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.146401.0&scm_id=1007.13339.146401.0&scm-url=1007.13339.146401.0&pvid=c3dcc468-4930-4773-bc9c-319ccf7b9847 At first glance they look the same and being Chinese the price difference is huge, less than 10% of the Swiss version but too expensive to take a wild punt. Some Chinese tools and equipment i have purchased have been absolutely brilliant. Does anybody have any experience with this tool?
