About 9 years old when I got a Weeden Steam engine , and I was thrilled. My dad knew steam and taught me to respect it. Rich

Yes, for scale of steam or old engines, the head thickness matches the thread diameter (100 %) Modern screw standards have it about 60 % Rich

Two sources I have only purchased from the first vendor--good stuff ! Rich https://godshallscustommachining.com https://www.modelmotorcars.com/

OK, My boo-boo Mark I did receive a email yesterday and replied to you - Did you get it ? I thought you sent me a second email at ( "Yesterday 9:01 PM) which would be after my email and that's why I said no. So now I just received the same early email ( 2 nd time ) ? This is fun !:) Rich

Mark, I did not get a email in the last 24 hours Rich

Mark, I just found your postings and am very impressed with your work and progress- outstanding ! I had a smile on my face when I read and saw your Valve Chest challenges . Now that is a very tough part ! I spent 6 months trying to do the chests alone and had 56 casting attempts --all failed...

K2 On the contrary, you have made a great comment. On several occasions , I have been asked to repair models that resided in Museums or personal collections and I am amazed that these models made 100 or 150 years ago do not have the modelers name or date on them. Not all these models were...

Bill Huxhold (RIP) my friend, made a drop dead gorgeous model that I saw at the NEMES meet in October 2014- I also loved that engine ever since seeing it at Kew Gardens H Here are some pics Rich

Found another Roller pic on the net but not sure of origin Rich https://imagearchive.com/proxy.php?image=http:%2F%2Fi11.photobucket.com%2Falbums%2Fa188%2FOldDog2%2F83136021_p5GfEG5r_BurtonIMGP4443.jpg&hash=0f6fb827e12c294ce46a9da9adeca342

Yes, we tried the air mist approach ..very dangerous IMHO and messy You have fine chips and coolant mist blowing out at 150 PSI ... a no no in our shop We had to tent the lathe with poly and that acts as a restriction on viewing work. You could wear a full face shield I guess..but the chips...

Pat, I really can't comment on gun barrels as I never made one. The one central concept of gun drilling is to rotate the work piece with a stationary drill (1.) But Professional drillers also rotate both the work and the drill (counter-rotate) (2) and most of my work was rotate the drill with...

Mordecai. Yes, I do not want to discourage you, but I feel you should be armed with facts about Gundrilling ....to help you. Yes , 1,000 PSI can work, we had instances where we drilled on a Lathe that was used normally for ordinary work but we needed drilling so we used it and ran at 800 PSI...

David, I took a look at your reference posting. Pretty interesting approach. Not sure I understand the do not withdraw comment ?? Any info on creating the crease in the tube ? The poster may have some se of this approach. Please remember, my post is what is done commercially.. hobbiests always...

Done lots of Gundrilling to 40 " depths from 3/8" to 1" in Diameter and also designed and built a Gun Drill platform /system I do not want to discourage the poster as sometimes great things are discovered by experimenting and doing things that no one else has done So let me say a few words...

Morton original was 1.625" Sigler's revision drawing which Bruce Satra used is 1.620 " Rich

Green Twin is right on and I have one small comment. Years ago I was casting a 16 inch flywheel and failed several times, until a foundry old timer told me to never do what I was doing- I was adding vents and risers without success. He said to " never pour rings flat" , always **** the mold a...

Kyle, Your line boring on the Lathe is exactly the way to do it. Great choice on using 7075 ! You can save time and money using the Bridgeport to rough out the hole. I am not familiar with the block you are purchasing , but it needs to be square (parallel surfaces) and the hole centered between...

Casting gears goes back over 200 years or more Here is a photo of the pinion gear on the Hypocycloidal Pumping Engine in the Henry Ford Museum in Dearborn ,Michigan. The engine was built by Matthew Murray of Leeds (UK) about 1806. The gears are magnificent and have a 17 degree Pressure Angle ...

Just accidentally ran across some information about a Buffalo Springfield Roller Apparently they have one in Jacktown Pennsylvania at the Blue Mountain Antique Gas and Steam Engine Assn https://www.jacktown.org/ Didn't see a picture of it at the above website, but didn't do a in depth search...

Here is a 24 Pound Cannon I built 30 years ago. The plans came in a school (right) machine shop drawings book ( 1940's ) Added a few details like the water pail,charging cup, swab and stuff. The second picture is wrong as the pail was not for cannon balls, but they rolled off the mantel so it...
