globe valves and fittinga few pics of the steam valves ive just completed. also pictured is a rough bit of brass i "cut "them from. i started to take pics of the making of the valves but with trying to work out the post with pics i STUFFED UP!!  3 HOURS WORK DOWN THE DRAIN !!! so i forgot about taking pics and just made the globe valves. each globe valve took me 5 hours each!!!! they are simple to make but are very time consuming. if i lived in the states i would just buy them! but ive made mine to 1/4 bsf so i can screw them into my mamods.

Well done Glenn, they came up nice.
Every engine should have a throttle on it!! |

i need eight of them and at $50 au each????? and then they are 1/4 ME and i would have to make adaptors. if i lived in the states i could get all that i need for $120 but here in oz $400 to $500... its the postage and tax that kills the wallet.

Wow ....talk about homemade!
Nice work! I cheated and used small brass draincocks (plumbing parts) for mine ...I didn't wanna pay $30 for those fancy little valves that probably leak anyhow. Jim |

Great work Glen.
I know what you mean on prices. To plumb all my engines up to my boiler cost me over $200 with all the valves, fittings, pipe, T peices etc. |

That looks very nice IMHO!!
How did you do the fittings to the brass nipples on the pipes? AFAIK the"contact surface" should be 60°. Did you use a countersink or drill?( I found that a 4 mm drill works and seals, if the diameter isn't too large, but ideally a countersink should be used I guess.). Haven't done valves though, just pipe connections. (I should have seen your post earlier, just ordered four valves. 
It would have inspired me to make my own. but next time... )

As much as I hate to admit it, I used one of those on the OKreation engine. Worth every penny, and does not leak a drop. Works mint.

thanks guys. they are worth making . anyone with a small lathe or adapted drill press could make them. all i use to make the small spindles is my drill press ...graver and files .
i found this listing. http://cgi.ebay.com.au/Live-Steam...faultDomain_0?hash=item1e587f795a the listing has a pic of the plans. also on our sister forum there is a pdf to download.

a second thought to the ebay listing...... not really knowing how long the "t" is you may experience difficulty in tapping the thread which is why i made my "t s" a little longer. in the download pdf the plans dont give you much depth to start a tap for the spindle which is where i "stuffed up" hense i made a pattern . the angled globe valve wasnt made from my cast "bodies" i used a small length of 1/2 round brass and screwed and loctited in a seat.

Hi Chainsaw, Very interesting post. I am just about to buy 4 finished globe valves within the next couple of days. I think the web page address for cast kits would be ideal for my purpose. As I have not done this before do you thing that I could produce valves from this kit using a small regular drill press without a lathe. If so I think I might invest in one as it would properly pay for itself once all 4 valves have been made. Cheers Mick |

no wonder i have problems if 1/8th BSP is about 1/2 inch. I think I will give them a miss then and stick to my aquarium airline taps untill i Sort something else out |

I think I will invest in a small drill press and play around. There is only one way to gain experience and that is to try my hand and learn by my mistakes.
A minor setback is a lack of workshop. I live in an apartment and already my soldering and other small works that take place in the .living room with a small Black and Decker type work bench is beginning to look out of place. Anyway reading your thread gives me inspiration. Cheers Mick |
