You should make more videos demonstrating your tools!!!! Seeing someone use a tool from your catalog makes it much more useful to a prospective customer! Thanks!!!!
I know this video is 10 years old and there's no replies on it, but as of the current moment, this tool isn't available on your site, the link goes to a 404 page, and nothing shows up when searching the SKU or name Springwinder. Shame, I really wanted one after seeing that demonstration. I'd recommend adding something like [Discontinued] to the video's title of you no longer plan to sell it. Ideally, you'd leave the page up and it would just say out of stock if you still planned to sell it.
Where did you buy the chuck,, who makes the chuck, what's the name of chuck, or what do they call it, please Let me know? What Hardware store sells it. Thank you Amacko
