John, A little off topic :offtopic: --- Quote from: John Hill on April 23, 2011, 11:25:59 PM ---Acetylene is out of the question for the home shop nowadays --- End quote --- Why is this, is it considered too dangerous? DaveH |
| John Hill:
We used to be able to get a cylinder of acetylene, take it home and keep it as long as we liked paying only for the fill ups on an exchange system. But they stopped that as people were taking the cylinders home and bringing them back years later! Nowadays we have to pay a monthly rental on the cylinders the price of which puts acetylene out of the question for most home shops. We still have to rent the oxy bottles but they are much cheaper. Most home shops around here either do without gas or use oxy/lpg. Owning the cylinders is possible but where I live it would cost $50 to transport the cylinder for filling. Oxy/lpg is much different to use than oxy/acetylene, there is plenty of heat and it will melt (burn?) the steel tubes of the bicycle frame if there is too much oxy, the secret to brazing with it seems to be to heat from the other side which is rather difficult working with tube. New skills to learn. |

first test by aardvark_akubra, on Flickr First test, handling is, shall we say, 'sedate' and I could tell the frame is not properly aligned. |

John, That sure is a novel project, but I would personally like to see another wheel, especially when trying to carry a lathe or mill around in the box. John |
