Glad to hear that it was tested. I have seen so many that have been cobbled together and then run without a test. From the work shown in you video, I thought it would past a test, but had to ask.
Hi from Tasmania, Australia. Lathe and Steam novice but love your youtube help. Thank you. QUESTION.. What is and how do you make a 90d drill bit. Google comes up with all sorts of garbage.
@@myfordboy Great thanks for your feedback. Have made the valve and it seems to work much better than the commercial one I purchased. Keep up your good work. Cheers Mike
dear mr. you are a genius! beautiful work. I have a question. are you a boilerman?. please send me the name of some book. thank very much. From Argentina.
Hi, Informative & enjoyable as ever. The SV design interested me. I don't see a way of adjustment without removing it from the vessel i.e depressurising and repressurising between each adjustment. Not convenient. Have I got it wrong? Regards.
+Peter Gregory The object was to simplify the safety valve design. It's the same design as used by Mamod. Yes you would have to remove it to alter the pressure setting. I connected the boiler to an air compressor to set the valve so it was no trouble to switch off the air and decompress whist making adjustments.
+ShamWerks You cannot thread right up to the end with the die so the treads are removed close to the shoulder. If this were not done it would not be able to screw right down.
+ian bertenshaw To set the pressure i connected the boiler to an air compressor and adjusted the regulator until the valve blew off at the pressure i needed.
I have a Myford M Series with that same 4 way tool post. Where did you get the holder for your parting tool as seen at 2:49? Or did you make it? By the way, your videos are awesome!
I'm not into steam modeling myself so I don't want to email them, but do you know if these are in any way affordable? www.miniaturepressuregauge.com/model-engineering/
You know the saying. If you have to ask... :) I just searched because I was curious if they existed, after wondering whether I could make a tiny one (answer : probably not).

Good idea to show the part in operation before showing construction.
that pressure relief valve is sweet!
I am a total novice, just a keen observer, thank you I enjoyed this video. Cheers Baz
......such incredible work, and your methods are a pleasure to watch.....thanks for sharing your project!
Great job as usual. Now I understand why using a half center.... Greetings from France
I miss working with a lay but having long hair now to be near a lay is a scarry thought haha wonderful work and great info
Hello! I will soon be acquiring my first lathe, so is there any way I could get the plans for this safety valve? Thanks for the in depth tutorial!
Leave your email and I will send it to you.
Superb part. Did not know that it's possible to do that and how, Great class.
Thanks
that safety valve is so cool :o
Yes, that would indeed simplify things. Thanks for the reply. Regards
Experienced and skilled hands indeed.
I wish l had such a beautiful machine :)
Nice work
Amazing work!
Você é um grande profissional. Seus vídeos são muito instrutivos e inspiradores. Deus o abençoe.
@ian bertenshaw
I think with the spring-force and screw-in depth of the nut. The correct pressure must be estimate. ;)

This is fascinating!
So pleasant to watch! Would you share the drawings for this safety valve?
Email me and I can send a copy,boiler too if you want. myf**dboy@yahoo.co.uk
does it matter the size of the boiler?
What psi is that valve set at? And what would you say is a safe psi to have these things at?
I set it to 30 psi. Boiler would be good for 50psi.
Hi from Tasmania, Australia. Lathe and Steam novice but love your youtube help. Thank you. QUESTION.. What is and how do you make a 90d drill bit. Google comes up with all sorts of garbage.
What do you mean by 90d?
@@myfordboy in your video you use a 90 degree drill bit to cut the valve seat. I am not sure what type of bit that is.
@@mikeb3619 It's a countersink drill.
@@myfordboy Great thanks for your feedback. Have made the valve and it seems to work much better than the commercial one I purchased. Keep up your good work. Cheers Mike
dear mr. you are a genius! beautiful work. I have a question. are you a boilerman?. please send me the name of some book. thank very much. From Argentina.
The only boiler book I have is Model locomotive boiler making by Alec farmer. It really covers larger boilers.
Is your "silver solder" actually a silver brazing alloy? If not can you say exactly what it is? Thanks.
Yes it is it contains about 55% silver.

Yes you would have to remove it to alter the pressure setting. I connected the boiler to an air compressor to set the valve so it was no trouble to switch off the air and decompress whist making adjustments.
How many bar pressure is the maximum for such a boiler?
I tested it to 90psi for a 40psi working pressure.
Great video, as usual. If I may ask, why the undercut above the threaded section?
+ShamWerks I would assume for an O-ring seal, but that's just a guess on my part.
+ShamWerks You cannot thread right up to the end with the die so the treads are removed close to the shoulder. If this were not done it would not be able to screw right down.
myfordboy Thanks for the answer - makes total sense.
FireoftheGreeks Why would you respond to a question that was not asked of you and you don’t know the answer?
How many PSI would that safety valve be?
30psi
ok so how did you set it for the correct pressure ?
+ian bertenshaw To set the pressure i connected the boiler to an air compressor and adjusted the regulator until the valve blew off at the pressure i needed.
+myfordboy How did you determine the maximum pressure that the boiler could withstand?
+Nick Tuckwell There are published calculations that can be done but none were made for this as it is just a smaller version of a published design.
+myfordboy cool, thanks for sharing the video
So no water pressure testing?
You forgot to add this to.your boiler playlist, I think.
Are there drawings available for the safety valve, and/or the complete boiler?
Thanks.
great project and video!
I have plans for the safety valve and a sketch of the boiler. I can send to you if i have an email address.
Thanks, I'd appreciate that!

+ThunderDog I made the parting tool holder. It uses a standard parting blade.
very good fellow !
you totally forgot about the left-handed smoke shifter!
thanks for info
Muito bom companheiro !
這師父老經驗尺寸拿捏很準
Hi, the 90 degree drill is like a counter sink bit, correct? I always learn on your videos!
+JC S Yes a countersink drill.
+myfordboy Thank you! I always learn something with your videos!
Nice video, but did you do a hydrostatic test?
+steamboatmodel My model engineering club boiler inspector gave the boiler a hydraulic and steam test.
Hell0o!What sort of burner and gas do you use when silversoldering a model steam boiler?Best regarsBjoern JansonSweden
I have a Seivert propane torch with a selection of different burner. You need to heat up the job quickly. Made in Sweden!
Nice!
I'm not into steam modeling myself so I don't want to email them, but do you know if these are in any way affordable? www.miniaturepressuregauge.com/model-engineering/
Just send an email asking how much they are.
You know the saying. If you have to ask... :) I just searched because I was curious if they existed, after wondering whether I could make a tiny one (answer : probably not).
I once made a working pressure gauge 3/4" dia and used gears from a watch. Very fiddly.
Muito show
I wise all the best
Ok
