I'm trying to build an antenna with a base section of pvc. I can use from
1/2" od to 1" od with no problems.
What I need to do is join a schedule 40 pvc nipple to a male 1"x14 threaded
I don't believe any std pipe thread and size will match up with that.
If it won't, I thought about using 3/4" pvc and running a tap into the open
end, and then screwing that down onto the male mounting stud (the 1" x 14).
Is a 1"x14 tap fairly common? Will my way work?
Anyone have an easier way?
Got a vexing problem I'm looking for a solution to.
Got a '70 vintage portable air compressor. Nice unit. Good sized tank, and
a roll-around. The compressor pump broke a crank recently. It's an old
Campbell Hausfeld. They no longer have parts support for it.
I don't want to just toss out the whole thing because of a bad pump. So,
the thing to do is to replace the pump---but inexpensively----because I can
buy a new, similar complete unit today for approx $125.
I'm not having any luck finding a replacement air pump in the $35-$45 price
range (and yes, I've been haunting Ebay looking for one).
Anyway, I vaguely recall hearing about people who've converted auto a/c
units for this use. However, I don't know what it entails, or how well
those work out.
If anyone knows of an online guidance source for doing one of these
conversions, would sure appreciate it if you'd pass it along.
My grandfather actually used an old engine, I believe it was a two stroke
engine with a nice motor. If I remember correctly the compression was done
on the exhaust stroke. Nothing fancy there. Actually he may have just added
a pip from the spark plug hole. Can anyone help?
What you can do is use a York air compressor that was used in a large number
of vehicles. Here's a site that gives some details.
Scroll down and look at the Identification and Acquisition pages. Another
source if you prefer not to dig around a junk yard would be
www.onboardair.com . These pages are devoted to installing these on
Jeeps but if you have a motor and a belt, they'll work just fine. I'd
highly recommend you look for the largest version for your application.
I've installed one on my Jeep and it works wonders for me on the trail (and
off for that matter). You could also look for one of the new compressors
made by Sanden but they need an oiler to keep them running. And yet
another option, I believe the Dodge trucks use a twin piston compressor for
their AC's. This might even be a better option for you. You'll have to
do some research on that one though as I discounted it right off given
limited space under my hood!
Use a PVC cap (male or female your choice) drill a hole to fit the threaded
stud (bolt) and then use an appropriate washers and nut on the other side to
secure it to the PVC cap. Now glue the cap onto the PVC pipe.
To make it more secure, fill the section with epoxy and reinforce as
Thanks, Pipedown. I can work with that approach.
For Goedjin: not sure I follow. Are you thinking slip a 1" pvc mast down
over the stud and then put a hose clamp around it? If so, that wouldn't
work for my application.
