Fire Scope

Who would have thought this one up?

 

Ruben I assume.

 

It's entertaining though ! Talking of 'scopes, finally found 5 minutes today
to get the covers off my 100 meg Hitachi that went wrong last week. You know
nothing's built to last these days - it's only been 20 years since I
"borrowed" it off the last company I workd for, and it's not as if it's on
any more than 350 days a year, or 16 hours a day ... Anyways, my trusty Bob
Parker ESR meter quickly pointed me at a 2200uF cap on the -12v rail.
Completely open. It's amazing at how far electrolytics have come on. The
replacement was about half the size or less than the original, and was a
better temp rated 105 deg over the original 85 deg.

Wow, that's cool! Of course I'm admittedly a pyro, but still!

 

Yeah I agree that is pretty cool! Anyone have any info on building one
other than the obvious?

 

2.5" PVC tubing, 2.5" speaker maybe some putty for the end where propane
is fed, aluminum foil. Glue the foil to the area where the holes are to be
drilled. I'm guessing the holes would be 1/4 inch.

 

An iron pipe would be a lot safer.

 

Yes and alot harder to drill a hundred holes in not to mention a lot
heavier.

 

I had considered using a piece of steel electrical conduit for this project
so that it wouldn't be too hard to drill.

That would work but still would be tedious drilling it out not to mention
you would have to buy a standard length of it if you couldn't find scrap.

 

Thin wall, or rigid? Thin wall will require a deburring tool to
remove the internal burrs. Thick wall is the same as galvanized water
pipe, but with a smoother internal finish.

Hmm.. Guess thats why he used PVC and aluminum tape. Much easier.
