Svimmer Posted January 7, 2018 Author Share Posted January 7, 2018 http://bildeopplaster.no/BSH Did not turn out perfect but with my skill on a lathe i think it was ok. Second time ever using a lathe Link to comment Share on other sites More sharing options...
cevmarauder Posted January 11, 2018 Share Posted January 11, 2018 (edited) Looks good. I'm not an expert with my lathe by any stretch. Cutting the bevels can be tricky, especially if you don't have a compound slide.You can anodize that aluminum pretty easily--google for tutorials on home anodizing. I usually leave the piece on the lathe to polish it--800 grit sandpaper all the way up to 3000, then a decent polishing compound on a chunk of old cotton t-shirt. Degrease, do a quickie home anodizing treatment, and you've got a set that's slick as a duck's ass. https://www.youtube.com/watch?v=Cp2gHZaZ-1Q Edited January 11, 2018 by cevmarauder 1 Link to comment Share on other sites More sharing options...

dagabu Posted January 13, 2018 Share Posted January 13, 2018 Sondre, You may wish to bring that taper in a bit, don't exceed 45° if you can help it and keep the shoulder as sharp as possible. If you search for "fundamentals of powder compression", you will find that most of the compression for the nozzle clay will be radially placed along the taper and not beneath the nozzle ram. Decreasing the angle to a maximum of 45° will give you better compaction and if you do decide to trim it up even more, 30° is plenty for a gerb! Also, consider using a lighter hammer and use many firm "taps" to settle and "sinter" the material so it forms a solid mass all the way through. Using a heavy hammer or using heavy hits on a nozzle with an aggressive shoulder angle can cause breakage and rupture in the tube and will almost universally allow the high-speed gasses to erode the wall where the nozzle, grain and tube meet. 2 Link to comment Share on other sites More sharing options...
