    Re: End Of An Era

    Glad for you, SJ. I'm going to be having to do just exactly what you're doing, with the exception that I don't have anywhere to go, or the money to get there. I finally got the major tools to do all...

    Re: Clampable Welding Surface / Table

    Back in the day when I worked in engineering research, a large part of our work concerned pulsed plasma jets, and continuous plasma jets using a feed gas into the plasma chamber. We always had...

    Re: Clampable Welding Surface / Table

    Bill, I like the idea of the table with slats, although I see the problem in compensating for heat warping. I wonder if you could get around this by welding some studs to the underside of one edge of...

    Re: Tube bending the easy way ?

    This is interesting - I did some bending using a homemade press that had a hydraulic car jack as the "prime mover". However, that was a one off, and not what I wanted to mention.

    A fellow in our...
  5. Re: Trike Lover - Reports of my demise are premature

    Thanks Bill. One day soon I'll post a YouTube video of myself doing Eric Clapton's "Layla" - an all time favorite of mine, and one that should demonstrate that most of the important bits are working...
  6. Trike Lover - Reports of my demise are premature

    Hello everyone,
    I just wanted to pop in and say hello, and pass along a couple of pieces of news. I guess the most important one is that contrary to a rumour that has begun to circulate, I am very...

    The complaint is an interesting commentary in it's own way on how some individuals will approach a project. I worked in a research lab for many years, so making up a basic sketch and then...

    Re: home made heat sinks

    I'll just chime in here with my two bits worth of being an "occasional" stick welder for 30+ years before getting a MIG setup.
    What John has said is bang on. Many years of bodging with a Lincoln AC...

    Re: Was brainstorming today.....

    I don't know if anyone has played with multiple step pulleys and v-belts. In the process of clearing some of the tons of unneeded or unwanted stuff out of the basement, I came across and old Beaver...

    Re: Lightning Generator!

    We used to get big blocks of Teflon from the same guys, and then the machine shop boys would go to work on them to make chambers. I don't know what it cost - a lot - but we used a lot of it, and it...

    Re: Lightning Generator!

    Brad,
    just curious because this goes over a lot of ground I used to work with when doing research - what are you using to trigger your discharge? We used to use a 3-electrode gap filled with Krypton...

    Re: Lightning Generator!

    Hi John,
    You're sure right about the absent-minded part. We used to strip off everything metal at the lab door - even rings and belt buckles - and operating the monster was a two man job. We each...

    Re: AC electric motors?

    I guess I'm not looking in the right places on the HK web site, because I haven't found a 1 kW motor for $50. I'm sure it's there, I just don't know under what heading.

    Re: AC electric motors?

    Yes, an epicyclic gearbox would be a reasonable way to go, if one had the materials and machinery to build one. I don't know, offhand, what the ideal (or a range of ideals) output RPM would be, but...

    Re: Electric Motor(s) For Trike

    Well, I guess the dual-motor controllers are out there. The limiting factors, assuming you used a hub motor, are the size and weight of the battery pack, and the overall vehicle with rider, and the...

    Re: River's Aurora

    Thanks Charlie,
    I'll give them a phone call rather than faxing an order letter. If I asked nicely, they might ship U.S.P.S. as you say, which avoids the unwelcome $50 "extra" when delivered. I will...

    Re: River's Aurora

    Interestingly, I placed an order with a standard cover letter with this company after seeing this, and the EBay ad.

    I received a one sentence response:


    "we no longer ship to Canada".

    Re: AC electric motors?

    True enough - at one time we used to call them "universal" motors. I don't have any figures for efficiency, but that's one of the reasons I tossed this out.




    Yes, they seem to be well made,...

    AC electric motors?

    I know this idea sounds totally off the wall, but my brain keeps coming back to it.

    There are all kinds of variable-speed 110 VAC power tools out there - a 1/2" drill, for example. There are also...

    Well, got my piece of SAE 4140 5/8" shafting today. Already heat-treated. Got a 5% discount as I am now a senior, having passed the double nickel at the end of August. FWIW, I watched as they hauled...

    Those little 24 volt "farmers welders" used to be sold by quite a few smaller hardware outlets around here, back when we still had "hardware stores" and not retail cathedrals, and they...

    When I was working in alternate fuel/plasma research, we had a whole room full of these or similar capacitors. I think they weighed about 100 lbs each. Discharge voltage was 100 kV - I forget what...

    I may end up doing the same - I seem to recall you and I both had the same problem with getting 48 spoke rims, and got them from the UK. I may PM you for the name of the UK spoke supplier...
