Too make that base casting a little simpler you might want to make it look like the original. The original had no lip around it. When I made mine from the casting set I removed the lip and blasted it. Bob

How I got started was a lot like George B, plastic models, air planes on strings and model trains, etc as a kid. Then into woodworking in my early 20's, made furniture stuff and enjoyed the end result. Then it happened, in 1974, I was taken to a live steam club and saw those engines running on...

Lloyd-ss I agree with you completely, its been disappointing watching the combatants. I am waiting to see who actually gets the last word in whatever that is. You know they could have taken it off line with PM and spared us their child like behavior ie who is king of the sandbox. Me I just...

When my granddaughters started learning machining they were 8 and 10. I told them we always make the large part first that way when we muck it up we can use it to make a smaller part. Even after 48 years of model building I still start with the large part first if it makes sense. As you...

Here is what I used to make a part (4 of them) which is part of the valve assembly for a Bates & Edmonds 25HP model I have been working on. In addition to the arc sides, and a shaft hole it needed two tapped holes at 90 degree angle to secure it to the shaft, a 2-56 and a 0-80, see photo. The...

Paul also sold both spark plug and Ignitor versions which gave 4 combinations. I picked up a partially completed ignitor air cooled, need to finish it .

I sent you a pm I will take it Bob

Gen had the same issue with the Hampton, I sent a note off to Aaron on this and got a response Thursday that he would contact the person in charge of the hotel stuff to get it resolved. At least the Hampton person said she would give Gen the new rate when she was made aware of it. Bob

Hi George, I recently tried to contact Ministeam via email, specifically about the 1/8th scale Galloway drawings I redid for them and some other questions, never got a response. Have you been able to contact them recently? Bob

I had never built a hot air engine, so I consulted some friends especially one who had built many of hot air engines as well as selling castings for them. Page 2 of my document has the changes I used and some of the whys. Here is a link to an article in Gas Engine magazine explaining some of...

That displacer piston is the opposite, the copper should be on the bottom for max heat transfer, and stainless on the side to minimize heat transfer. Stainless is a poor conductor of heat. If you are daring. I would replace the bottom with copper, about .032. I used type M copper pipe...

Yes that displacer cylinder made of copper is an issue. A question is the bottom of the displacer cylinder copper? I have some ideas on how to minimize the copper issue. Remember friction is the bane of hot air engines, zero is the goal. The dragging of displacer piston is an issue and must...

Very nice looking model, if I may ask what is not running for you the way you would like? Bob

K2 Here is a picture of the 14” gauge taken around 1987. I co-owned it with friend in the 1980’s, we laid about 1200’ of track at a Threshing show grounds. I sold my share, and since then it was sold in the mid 90’s. It was built in late 40’s early 50’s by a gentleman in Illinois and ran at...

K2 You guessed exactly what I was going to propose but really would like to see his application. Wilesco makes a real nice valve that doubles as the filler hole for it largest boiler, a D22. It appears it is set for about 1.5 bar ie about 22psi if I read the picture of the gauge on their site...

Mike A photo of the boiler would really help understand what is being attempted. What is the boiler powering? You are describing a water tube boiler with 3 water tubes 3/16" x 5 3/8" long connected to a 1 1/2" tube 8" long. Total volume of the tube is 7.83 oz and volume of the tubes is...

krypto I have those in a PDF, also lots of views of the machine. I will make up a file containing all the info I have and upload it. I have uploaded stuff to vintagemachinery before, Laidlaw Bandsaw and All American Die Filer details and drawings. I never looked for any information on...

I think these were available in the 1950's. I have attached fliers that were in the tool box that was built into the custom cabinet that housed Dumore. Bob

I have a Dumore that is outfitted with x-y table, light, magnifying glass, speed control, depth controlled table that has balance weights so it moves only if dial is turned. It has a magnetic chuck that allows you to center a bit for zero runnout. Smallest it goes down to is a #71 (.026). I...

Got this from Paul last week
