  1. If you are going to make your own pulleys the taper is around 1 deg on each side so turn your pulley parallel then turn each side until the cut comes close to the centre leaving a small parallel strip in the middle. Only one of each running pair needs a camber on it, the cambered pulley is not a must have but makes the belt run much better
  2. I have finally got the tooling for forging a conrod for my project motor bike. This has been a very round about journey and during researching this rekindled my interest in knife making and these things are the reason that I aquired my Massey power hammer. There is a lightening storm happening here at the moment and seems to be making internet play up in down loading pictures or the wife is on facebook or both (sigh) but anyway I am copying a conrod of an old KTM I used to have and just changing the centres I am going to use EN39B steel which is a case hardening steel and high tensile. Very excited about this part of the project of the much modified engine and just maybe in the future may turn into something I can sell

    Freezing Propane Tanks. A Different Solution

    I have been talking to one of the gas suppliers and he is looking into a vaporizer for me, if i have more than 100Kg onsite i have have a permit at a couple of hundred dollars a year, between bottle rentals and permits this must be a racket run my some under world outfit. The bottle rental thing is something that if i think about it too much i start talking through clenched teeth and muttering swear words that cant be repeated in gentle company like this.

    Freezing Propane Tanks. A Different Solution

    Well I went and got a cup of tea and some buscuits and read the pinned post and I still havent got an answer to my question as I really need to have my bottles outside if I have more than one, I wish there was the big propane tanks here like I saw in Merica while I was there years ago but they dont seem to be available here and I dont wish to have a giant bank of bottles if I can avoid it. i have done most of the heating tricks that were talked about well the less dodgy ones. cheers Beaver

    Freezing Propane Tanks. A Different Solution

    I have been using one of my LPG burners over the last few days to reduce the scale forming on blanks for rivets and my 45 Kg LPG bottle pressure kept on taking a dive, Without going to the trouble of running water over the bottle to try to maintain temp how do others deal with this problem. In the future I wish to run two of these burners (3/4 inch body) which are not big off two bottles in tandem which I though should cover the req drawoff, Has anyone tried a Vaporizer that you supply with liquid gas from the bottle which would remove the problem. This is done in large instalations but what about smaller scale?

    XXL coil springs, usefull ?

    I have lots of spring steel around 45mm dia from digger track tensioning springs and have made punches and drifts with it and have found with mine if you just let it air cool is good for punches But I dont know what steel it is but probably 5160ish

    1m X 1m Side Blast

    Just my 2cents worth but why not keep it simple and use dirt or better still clay? it wouldnt blow around and when dry and fired it wouldnt be dug into as easily and its dirt cheap as well Just like the JABOD

    Simple folding Knife or Peasant Knife

    Its all done and I have used a coffee etch which did improve the contrast and using 2000 grit sand paper really helded as well, I had to make 6mm screws into 4mm screws which was a bit fiddley and the barrel was turned from a bronze bolt. I think I will make some more of this style of blade

  13. I am having a go at making some folding pocket knifes, the blades are made from Sawmill bandsaw blade and railway track, I am going to try a coffe etch to see what happens

    Oxy Acetylene regulators

    One way of getting an idea if the old regs are dammaged is to turn the cylinder on but just leave the torch turned off and if the pressure creeps up on the outlet side then they are faulty and can be dangerous if the fuel gas is acetylene as above 15 psi it can become unstable. When you turn the cylinder valves on do it slowly as if you just crack them open the high pressure gas can surge through and this slams the internal metering valve onto its seat and will damage it, with care regs last along time. You can usually get new gauges as well and fit them to the old regs, just make sure they are made for use in a gas set and a side note dont use copper pipe as hose joiner with acetylene as it can form copper acetylide or something like that that is shock sensitive if i remember correctly.
