GreenTwin, Very informative post ! I forgot about the knife gates . Didn't know about the Phosphorus application . Used "Silver" Coke ( The best) in the Coke Cupola and had to run my forced air supply through a 3 inch SS Tube first, that was buried in coals in a Weber grill to preheat the...

Dazz- Yours is a big order and I admire you for the undertaking of it. Be sure to record your work. Years ago I built a cupola and poured iron for my model steam engines. There is much to learn about iron and fluidity has it's tricks . I was guided by a real iron metallurgist at the time who...

Perhaps this has been said before, but let me rephrase the commentary that talks about rubber tires and crowned wheels. There are two kinds of Bandsaws - and they are not the same- you must realize the difference ! The conventional Vertical Bandsaw ( that we mostly see ) has a crowned wheel...

140.7-140.53=.017mm= .017mm x .039=.00663" shrink which is perfect for your ~ 6 Inch Wheel Rich

Sure does Collin ! The shrink is used to have the proper Tension in the rods. Those not familiar with Thermo shrinks like rings on disks or wheels--- should know that size for size a Thermo Interference fit is twice as strong as a press fit ! ( and you don't need a Hydraulic Press to...

clockworkcheval- "So the linear expansion is the diameter expansion. " Absolutely correct ! -but there is one thing to keep in mind, and that is differential expansion. If the disk and the ring are the same material, like steel/steel then a .005 shrink fit for instance is the same regardless...

Forgive me for using Inch and Fahrenheit as a guideline, but I did this extensively when working . The basic formula for Steel is called 5 ball 63 so it is easy to remember ( 5 ball means 5 zeros) . That means that steel expands at the rate of .0000063 per inch per degree F. Now that is...

yes, that link from 2020 no longer works Rich

I think we are missing a word here. The Deckel is a very fine tool and cutter grinder. ( and as mentioned was primarily for Deckel milling machines and single point cutters- but it does others ) The Ops photo and the Quorn , are "universal" cutter grinders. The range of a universal cutter...

I Thought you may wish to see the setup I have . My former shop ( former house) had a shop vac outside and the suction line went to the eaves and into the shop and then my vacuum hose dropped down from the center of the ceiling . It worked OK, bur needed a separator, So when we moved to a new...

Kop, would you be so kind as to post the size of the table on the Benchmaster ? I want to compare it to the Atlas Horizontal and the Diamond/Vernon/Sheldon mill I had. Thanks Rich

That is awesome ! I spent 10 years trying to find one. Found an Atlas and bought it, but had my heart set on a Benchmaster... gave up at the suggestion of a friend and got a Bridgeport but they still bring me a smile Rich

My friend is out of town until next week, so I don't have that resource Will check my library What do you mean "non-standard teeth " is it a commercial gear or did someone cut it ? Rich

You are correct, the Van Keuren Tables only function with standard Involute Profiles , but let me ask a friend who had a Gear business to confirm. Rich

Here is what it looks like You can find them at on line book sellers for 3-5 dollars Rich

I have a copy of The Van Keuren Book which gear makers use for quality control measurement. By using a micrometer and two gauge pins , the exact Pitch Diameter can be read, or measured . Van Keuren sells the pins, but they can be made . While I have a set of pins, I have made my own in the past...

This will not help you currently , but many years ago a friend built his 9 cylinder radial and I cut the cam ring gears for him at the time. Commercial gears are made on the loose side so there is no " binding" in the customers application. When i made his gears, I made multiple pinions , each...

Less expensive than UHMW is Formica and it comes in thin sheets at home supply stores. We used Formica when our hoppers would hang up with wet material. Do not run the vibrator UNLESS the auger screw is turning- They are a joint operation, else you get packing Also, Vibrators are directional...

I was a good friend of Rudy and that steam roller sat on his coffee table, while most of his model engines were in a cupboard . He was very proud of it and it was inspired by a full size roller he found near his home in Bridgewater NJ. I don't recall any conversation about plans for it , but...

Hi Mike. yes, a spotting drill or "starter drill " ( same drill) works very well and definitely use them if a ball endmill is not available. And get them in carbide if possible due to their rigidity . But when you do, try to go to 2 x diameter so you get the full support for the jobber drill...
