I have this kind, and I use it for most of the antique and vintage mainspring barrels when I need to replace a spring.  It doesn't seem very difficult to use, for me anyway.  I don't know how much you know about them or how often you've used other winders, so I will explain as best I can without intending to insult.
So far, I've had no trouble winding springs in either direction with the 126, but clockwise seems to be more commonly used.  Here I would advise: take pictures and study the barrel and how it is placed in the movement, and which way the arbor would turn - to be sure that you are winding the spring in the correction direction to load into the barrel.
After winding the spring all the way into the *winder's barrel*, it's a simple matter to slowly turn the crank back and allow the spring tension to settle into the winder's barrel.  Then you turn backward a little bit more to try to gently release the spring from the pin on the winder's shaft.  Take care to keep the spring from uncoiling out of the winder.
Then, if you've chosen a winder-barrel just slightly smaller than the watch's mainspring barrel, you line up the spring's hook or anchor-point just ahead of where it would latch onto the barrel's anchor point and, taking your time, get everything in line and gently press the button on the handle to shove the spring in.
Practice makes this procedure easier.  Get an old "parts" movement (a large old pocket watch movement to start) and just practice gently taking the spring out, and winding it back in.  Go slow.  Wear safety glasses.  Take note of the way things go together when you're doing it.  It gets easier.  Don't immediately start with a watch you have to repair. These winders are great once you get the hang of them.  I'm very fond of my own.

      Part swapper to part maker

      By Jon · Posted

      I would use some binding wire around the part before heating it. It protects the steel from being burned. I know that sounds strange, as you're going to heat it with a blowtorch, but if a part is thin and delicate the steel can literally burn away before your eyes, which isn't funny if you've put hours into the job. I bought some tools steel from Cousins a few years ago which turned out not to be tool steel, because it couldn't be hardened or tempered. I wasn't impressed, as I had spent two hours making the part for it to be useless.

      Questions about my Bravingtons Renown Mantel Clock

      By watchweasol · Posted

      Hi that’s what was meant by animal glue “ a glue made from animal products”. Ie bone , skin and other animal residues.  There was a place at Huntington YORK who used to boil down the ingredients. It stunk.   We used it in pellet form in a sort of Bain Marie on a gas ring  it was very good, didn’t think it was around any more with the modern glues,

      Balance cock stud screw

      By Zedster · Posted

      It's back to the drawing board I'm afraid. As pointed out, the Rodico trick is so fiddly and my pin vice jaws don't close in union. I tried but the screw is so small it's hard to grip the screw in the Rodico without it moving all over the place while trying to get it in the vice. I started to shake too much so gave up before the screw flew off somewhere never to be found again.  I'm now thinking that maybe I could bond the screw on the end of a bit of peg wood and then dissolve the adhesive afterward.  I just had another thought🤔 I have some really small PCB drill bits maybe I could drill a small hole in peg wood and push the screw in, as stated I only need to get the screw started.  Another idea 🤣 Magnetize the screwdriver to hold the screw 🤔

      Generic screws for unknown movements

      Yeah there is a spring under there. Hopefully now I can source a screw for the click and the bridges! Thanks for your help!

      Identifying watch for possible radioactive concern

      By rjenkinsgb · Posted

      Definitely worthwhile, if you are working with old watches - just be sure it's an actual Geiger counter, not one of the vast range of scam/fake "Radiation detectors" on ebay & amazon etc. that detect RF or static electricity...   In the mean time, I'd put the dial and hands in zip bags & wipe down the work area with a damp cloth to pick up any dust, then discard the cloth. The emitted radiation from radium lume is not normally harmful - but inhaling or ingesting a single particle of the material can cause serious long term harm, so do take care with it.
