Hi Steamchick Thanks for your comments they are all good ideas. I am battling health issues at present and hope to get back to making models soon.I have noticed in your comments from other threads that you can design ceramic burners, I would like to try one in my boiler but do not understand...

I have a question for everybody. Has anyone had a Stewart Triple running on steam

Hi Bob If you start this build I am happy to help any way I can Cheers John

Hi The draincocks of the side of each cylinder are standard from Stewart models. Let me know if more information is needed Cheers emers

Hi Alan John here from Kings Langley Blacktown area. You should visit Sydney Society of Model Engineers at Luddernam last Sunday each month check out our website. Will have a great time. Cheers John

Welcome Where are you in Australia. I am a retired machinist located in Sydney I enjoy machining and have had a love of 2 stroke engines forever. I am 73 now. Welcome again Cheers John (emers)

I used those regs to build my boiler almost 4 years ago. It has performed flawlessly since it was certified by our club inspector It is due for recertification later this year. Cheers

Hi Brian I am a 73 year old machinist and I have the same problem, I have noticed the the problem is not always the allen wrench itself but the hex in the grub screw being to large. I try to buy better quality allen wrenches and better brand grubscrews here In Australia I try to purchase Unbrako...

Hi Everyone Thanks for the comments I ended up with the eccentrics as per the Stewart drawings, where I made a mistake was I had the HP eccentric 180 degrees out. I could get the engine to run with only the HP connected on air and turn in one direction but when I connected the IP cylinder it...

Last for now update photos with displacement lubricator fitted thinking about a simpling valve so lubricator will probably be modified.

Next was the lagging of the cylinders the kit is supplied with some aluminium sheet I felt that keeping the cylinders insulated as best possible was important so I packed the space behind the lagging with bits of timber & glue before fitting the lagging. I made cardboard templates for each side...

I feel in writing mood now so on with my build progress I next made the Air pump & Water pump. Reasonably straight forward machining operations. Some pictures will show results.

Next came a real problem for me getting the model to run on air on all 3 cylinders looking at some other posts I was vey confused on what to do to get them all working on air. I noticed on some videos of others they would feed air to both the HP and LP cylinders and get the model to run OK. I...

It has been a while I have been working slowly and making some progress. I have had some paying work plus also, as I have had it said by others, you lose some enthusiasm for the project. I am back. My last post was the making of the transfer pipes they are finished.

Decided to make the transfer pipes using my home made tube bender have bent up the two pipes and silver soldered the flanges to the 5/16 pipe. Will silver solder the other pipe this week then will have to lag them more pics to follow.

Continuing on I have made the 3 Guide bars all straight forward as I have a surface grinder very easy to get them looking very nice.

I have been machining some more parts. I have not explained the slide valve setup the setting of the high and low pressure cylinders slide valves is very straight forward after setting the eccentrics on the crank I used the method described by steamingandy to do that . His picture build has been...

You are correct will try the other cylinders then get onto all the remaining parts. I can see the end still some distance to go but it is progressing well.

I looked at where I was up to at this stage and figured I could time the build and test it running on air. I used steamingandy's guide to time the eccentrics and set the slide valve in both forward & reverse and gave it a run on air. I am only doing the High Pressure cylinder today. It worked...

Next part is the piston rod easier made by doing it in two pieces so I turned the shaft then the crosshead then a keeper to contain the bush. I have to learn how to take better photos as some of my efforts are not worth publishing will keep trying.
