But you're wrong. ;D
Mostly.

Sheesh...slow down at all on this forum...and threads can take a completely different road.
 
It may be heard leaking sound when unscrew.

I remember things like this from Japan. I had a motorcycle once, long ago. The owner's manual
was some of the best comedy I've ever read. It had a caution in the event you passed a pedestrian;
"Tootle the horn melodiously and yell the warning: Hoi! Hoi!"
And on a gas powered saw; "Do not pull the cord to terminal".
I guess they wanted you to stay away from airports.

I got the pump that Pete suggested. At first I was a bit wary. For one thing the price seemed too low. $18. For another, there's no a label/etching/sticker anywhere on it indicating 'Made in ...'.

But I tried it on my bike and it did pump it up. I was real surprised. At first I couldn't tell it was doing anything...pumping away provided no/little resistance. Then I felt the tire. Nearly hard as a rock. A few more pumps and I could see the pressure gauge had definitely moved. I stopped at about 30psi.

Then I read the instructions...an excerpt...

Zee

These pumps are not for pumping up tyres they are high pressure pumps for the air suspension shocks that take 100-250psi. It would take you a week to pump up a tyre from flat. But you'd get there eventually. Take your 2" mountain bike tyre to 80psi and you'd have a seriously loud bang at some point.

Be careful doing your boiler don't ram the piston in hard, with no leaks you'll be at 100psi before the end of the stroke and your little boiler will look like The Fat Controller

Thanks Pete.

That explains things. I didn't know about the shock absorbers.

I was testing the tire tube frequently...I remember a blow-out when I was a kid. Took my bike (bicycle) to a service station, aired up, drove a couple miles back home, got off the bike, took 3 steps, then blammey.

 
Hehe, the best instruction manual "Gotchya" I ever ran across was American, and intentional.

It was a universal battery charger for Nic-Cad/Nimh cells (For Radio Control) and buried toward the end was this nugget of information: (Slightly paraphrased... my memory isn't that good, LOL).

"Reverse polarity: If you reverse the polarity of the connection it will reverse the flow of space time, resulting in the destabilization of the universe as we know it and destroying all life on earth. It will be all your fault."



 
Well then, we'd all better make sure we have our towels with us. Someone is bound
to try that!
 
Got a question.
You can think of this as my usual blatant way to keep my thread afloat.

I have some old bicycle tires. Any reason why I can't pull a Schrader valve out of one and use it to for pressure testing? (This newbie assumes it's a Schrader valve.)

What is the thread on it?

I'm sure that testing to 30 psi should be no problem but what is the limit? Are all same-sized Schrader valves equivalent when it comes to that?

Thanks.
 

Internal thread (to accept the threaded valve core)

* Metric: 5.30 mm OD x 0.706 mm pitch
* Imperial: 0.209 in OD x 36 tpi.
 
Or, go to a tire store that does truck service and buy a brass valve stem for big truck wheels.
You can cut off part of the brass stem (they are about 3" long) and solder it to an adapter that
will screw into the threads for one of the top bushings.
If you do that, take the valve out of the stem before you solder. There are often plastic parts in the
valve.

You have plenty of pressure leeway with Schrader valves. Some tires take 120 psi, or more.

Thanks PaulG, frazer, and Dean.

More soldering eh? Ah hahahahahahahahaha.

Actually, I didn't think you could do that. The stems on my bicycle tires are encased in rubber (if I remember correctly). I didn't know you can get something else.

Sounds like a trip to auto parts store is in the making.

Thanks again.

 
Something like this, Zee. For truck tires. Most car tire types are rubber, or chromed for fancy
wheels.

You should have no trouble if you just want to use regular solder for this.

Dean
 
I would have thought that the barrel from a bike or car tube woud do. Hack the rubber off, clean up with a wire brush and you'll find brass underneath. Remove the valve and solder into a bush. And replace valve prior to use.

Pete
 
Dean, LOL... I always have my towel. Well, almost always... I forgot it this morning because my brain felt oddly like it had been smashed out by a slice of lemon wrapped around a large gold brick.

Zee.... so when does construction start on the life size locomotive? I went back and read the first two threads in the "series" and found them every bit as educational and entertaining. Not to repeat anyones earlier mistakes, I owe you A beer if ever we meet. :big:

Oh har. Oh har de har har. Prior to seeing your post Dean, I went to Pep boys today (mainly to get away from work). They had a valve stem encased in rubber...and a valve chromed for fancy wheels. Darn it. $5.99 for chrome. $2.99 for rubber. The guy said there was metal under the rubber. I'm thinking "Can't I get that off? I got a lathe gosh durn it." So I went for the $2.99. I have no idea if this will work.

Like Pete said. I'll try hacking it off. Well we'll see.

The folks just left but I'm off to California this Friday (pleasure) and then probably Mexico (business...well pleasure too). Not much in the way of machining time. As it is...I see that I fell behind by more than 100 posts.

My folks...he's 84 and she's 82. They still bowl in the leagues...and go to state championships. I wish I hadn't smoked and drank as much as I did. (No I don't.)

TroyO...thank you so much. That means a lot to me. And since you confess to having read my other threads...you know I will hold you to that beer....where-ever you are. Just where are you?

............

So as I said...off to CA. Napa...San Fran...Sonoma...Carmel. Anything 'home machinist' related close by? Not that it helps...I'm going to be with family...they have their own plans. Wine, trees, wine, museums, wine, restaurants, wine...hm...maybe I won't miss machining as much as I think.
 
Zee, Have a great time in Calif. really sounds like you know how enjoy Calif.anyway lots of luck. larry
 
There is metal under that rubber, Zee. It's vulcanized on. I'm sure you can get it off, but I'd just get
a brass one so you can spend more time working on your engine instead of working on valve stems.
If you want to mess with the rubber one by turning it down, cut off all you can with a knife, then freeze
it before turning. Abrasives might be easier.
Brass valve stem easier yet.

Have a great time going places and goofing off!

The Monterey Aquarium is worth going to. Carmel is just a few miles down Highway 1. Well worth the visit if you like fish and other aquatic animals. If you pass through Pacific Grove wave to my grandkids as you pass by. :D

I'm in Denver, CO. Known as a Cow town and for skiing..... hmmm, I don't ski, or have a particular fondness for cows (Except on a plate... med-rare, thank you. I love food that used to Moo.)

So I'm not real sure WHY I'm in Denver.... but there I be, anyway. ;-P
