Ideas on what we did with the 27 mm bronze bar supplied by Jason

533 forum posts | Like many others among you, I bought a couple of lengths of the excellent bronze bar from Jason Udall. I thought it might be interesting to invite you to share any interesting things you did with it - if nothing else, it would be nice for Jason to know that he wasn't wasting his time. In fairness, I'd better start. The only thing I have had time to do so far was to make a roller for an anomalous climbing novelty.
The double cone was of course made by sticking two cones together. The cones have an included angle of 40 degrees. I was a little concerned about how to locate them; then I realised that there was a nice 1.03 mm pip left from parting off. I drilled a 25 mm hole in a piece of softwood with a wood bit, which was just enough to hold one cone to drill a 1.1 mm hole. Glued with Araldite, baked in oven at 65 degrees for an hour, which made it harder than I would have wished and was a b****r to clean off. The lash up in the first picture is just to work out the necessary settings to enable the cones to roll "upwards"; broadly making the two bars (silver steel in this rig) diverge more is positive, increasing the slope is obviously negative. You either have to work out the maths or do it by trial and error. I have embarked on making a nice oak stand with stainless steel bars. Bronze is ideal for this purpose; it turns well, looks nice and does not stain badly. Brass would need to be varnished to avoid this, or be polished every few days, and I think varnish would not help the rolling. David Edited By David Littlewood on 09/01/2013 19:41:18 |

533 forum posts | Jason (B), Very neat piece of work! I take it you made them in one piece, so no soldering will be necessary. How did you get the splendid elliptical shape so neatly, CNC? David |

![]() 25215 forum posts 3105 photos 1 articles | They are one piece, the spigot was turned one the lathe and the hole bored & reamed at the same setting. Part off a little overlength then hold by the spigot to finish the parted face. Then into the mill to drill the holes. The two larger curves of the "elipse" were done with a boring head set to cut with the tool the opposite way round and the ends were just done with good old filing buttons. This is not my photo but should give you an idea of how its done, mine being smaller were just held by the spigot rather than the jig shown. You can also use a similar method by having the gland mounted on the end of a rod in the lathe, either hace teh rod the dia of the curve and use the 3-jaw or a smaller rod offset in the 4-jaw. |

533 forum posts | Here is a picture of the finished climbing novelty - I was waiting to get hold of some 3/4" stainless.
Now, any more of you want to share the results? David PS - Why are the pictures coming out so small? The link I inserted is to one twice that size. Maybe, after months of having problems with huge pictures messing the line wrap we have now had some limit imposed. If so, it's too small. ...And now the bloody writing is too small. Why is this web software so c**p? Edited By David Littlewood on 30/01/2013 11:56:57 |

![]() 25215 forum posts 3105 photos 1 articles | I find that the forum makes any image hosted elsewhere narrow but if you upload to this site in my photos you can then click to enlarge the image. If using an external host such as Photobucket set the width to about 500 when you add the link at least then it stays in proportion but still can't be enlarged or just link to the image rather than showing it in the post.
