Got this blank and another the other day and was very excited to turn as it's the first watch pen blank I've tried. It was labeled as a sierra and I checked out the nib size on my components and was .4730, finial was .4700. So far so good..started turning and got to .5000 on both ends and got looking closer and saw these shiny spots (from hitting parts?) and worse a small chipout over the face of the clock (between 10-12). Was going to sand the rest of the way but now not sure what to do with this. Almost tossed but thought I'd check out the brain trust here and see if I can save, and more importantly if the other blank is going to be the same situation? I like my pens with a subtle taper and don't know if these were made to be thicker barrels or what happened? At the chip out the thickness left is approximately .006-.007 so I don't have much left. What am I missing??:frown: Thanks for each and every response. BTW the first 3 pics are the mistake and the last 2 are the future beautiful pen( I hope):rolleyes:

got to turn the end to size and let the middle be a litter thicker, the watch parts are small but a little thick, you can use ca and build it back up and it will be good as new .......
 
As Glen said turn the ends to size and the middle will be thicker. Looking at the profile of the blank I am not suprised you hit parts you have it really flat. Generally there is less than 1/32" from the tube to the shoulder on the bushing. Then adding to that (or subtracing as the case maybe) there is a layer of carbon fiber. If the watch parts are not perfectly contoured to the tube they stick out farther. Some of the watch parts are pretty hard to bend with a lot of spring back.

The CA that Glen told you to do should work just don't use to much accelerator.

Well most makers that make these will tell you there for a Vista .551-.523 OD turn smaller at your own risk. As you get close to final size you need to go VERY slow so your working with a near finish.

Anyway I know that doesn't help your currant situation. Now how would I fix chances are it was made from PR. Assuming it was made from PR (contact maker) and you did not put any CA or wax or anything on it you can recast it. PR adheres very well to it's self. It doesn't look like you tore any parts out. You could chip away any thin loose PR around that chipped out spot and recast...Oh and I would use pressure...It can probably be saved and then figure a Sierra Vista kit.


One last note I used to make these and no longer do so I can only give advise. Contact the maker they may offer to try a repair for about 1/2 what you paid???


Worth a try what ever you do don't use CA to try a fix unless it is an absolutely last resort


Good Luck
