Well, it all depends on what accuracy level you want ? Deep hole drilling has some considerations that rise above normal considerations Unfortunately, it conflicts with many of the "standards" we have learned in our machining careers or hobby. So let me begin : Lathe work- First know that that...

Yes

Understood Craig--You can't scale nature --Nice work you have done however ! Rich

Another thought on the reduced volume of the flame chamber. You may want to consider a ceramic lining to the chamber as it reduces the heat transfer and loss and the coating can be quite thin !

My Brother-in-law had a Mobil Truck Repair Van with Oxy and Acetylene tanks and some gasoline used for cleaning parts caught on fire . I arrived at the fire scene a few minutes later , just when the Fire department found out there was Oxy-Acetylene tanks in the van and they pulled back and...

All There have been many postings on various Forums about this engine and requests for drawings You may know that only a few drawings of the engine remain and required 20 years of study to gain their secrets I was able to focus this information into the only detailed and complete set covering...

I worked with (not for) several Aluminum Foundries and can add a few points to produce denser castings. The "gas" you are getting rid of is Hydrogen. It has a huge affinity for Aluminum and other metals. . Try to cover the crucible during and after melting to reduce exposure to Moist Air ...

Canyonman try McMaster Carr https://www.mcmaster.com/zinc-alloys/ Not sure which Zamak alloy that is , but you can check it out Rich

I spent my very early career in a can plant and have a few comments . Yes, Tin Cans have been used for over 180 years. The "Side Seam " and the lids (called "ends")were hand soldered with 2/98 (Tin/Lead %) solder ( `612 F temp) and many times the insides had lumps of solder. Even when done by...

Yes, You double everything , Particularly the port sizes and the dimensions between the ports must be doubled in your example The engine will still run if the supply pipe is small (1/8" ie) it just will not develop full power if the air flow is restricted. If you run on steam , the supply...

For really good journals, you may wish to "Superfinish" them https://en.wikipedia.org/wiki/Superfinishing I did this on my crank and the finish is superb. I used a old Remington electric razor found at a junk shop and modified it. The thing you want is free and fast vibration ! the wooden block...

Fascinating thread here, a mixture of experiences , theory, humor and personal feelings. I will not address them all except to say that having a smile on one's face is better than a grimace and real experience is better than theory and most important for all is sharing information !. With over...

Be aware that center cutting endmills have a 1 - 2 degree relief ground in the flutes which means that it leaves a convex , not flat, surface at the bottom of the hole. This means a 1/4 " diameter hole may have a .001 crown at the bottom - not flat, but not noticeable either Rich

Ken, I know you wish to learn and that was the reason for the question so let me add a little more to the above which maybe will help. Most Home Shop guys clamp things in a vise and think they have control...Nope ! One jaw is a Plane.. and when you look at 6DOF , the other jaw is a plane, but...

Ken , If you want to learn Jigs and Fixtures, it will help if you understand " 6 Degrees of Freedom" ( 6DOF) Unfortunately , Most of the discussions on the net are not machining related and are pretty esoteric in Physics and or Robotics . As a retired Manufacturing Engineer, I taught my...

I Think I have that book - have to look and will advise Up date yes, like new condition Go to my website which is StationarySteam dot Com And you can email me there Rich

Removing Paper contact cover on OLD Plexiglass/acrylic stock One heck of a problem. Most solvents will not touch it It isn't the paper so much , as it is the adhesive they used. I have some plexy given to me that is 50 yrs old The only solvent that ever worked easily was a aerosol can called...

Those online calculators are really neat, good resource . There is one problem however in that it does not tell you the ideal wire size. The Van Keuren book gives you wire size to match the Pitch Diameter Tangent Point of the specific gear. You may want to check your used book stores, or try...

Measuring Gears.. Several ways to do it , but they get pretty expensive equipment wise !. A really low cost way is to buy a 5 dollar book , which is really a Catalog by the Van Keuren Company. Here is one on Amazon , but I got mine for $4...
