Re: Current temp 4 degrees

Abnormally warm and dry in northern NM, which means our current daily range is 22F low to 55F high. No snow or rain for almost 100 days.

Be glad to take some cold and snow if you can find a way to ship it!

Re: Carbon Monoxide for Gophers?

Remember that nature abhors a vacuum, so the moment you start to get the gophers out of your field, the word will go out to the surrounding fields for volunteers to fill the void. You should set up the defensive line outside the area you wish to keep gopher free. Personally, I like the wire traps - ...

Re: TG 100 collets

You should be able to find tool holders that use TG collets for most milling machine tapers; back to ebay! I have made special DA holders using a Morse taper so it can be done. Getting the space between the two tapered sections in the body is essential so all of the collet closes at the same time.

Re: Getting Rid of Live Oak Leaves?

Push them into a tall pile and enclose with wire mesh. Water the pile once in awhile and add new leaves as available. It makes a great compost.

Re: Brown and Sharpe Micrometer

B&S is/was based in Providence, RI. I have catalogs dating from the 20's and 30's. They claim to have developed the first practical micrometer in 1867.

Re: Large Radius Turning

You are correct that the link needs to be parallel to the ways when the cutter is in the center of the arc, and I used the compound to feed into the part. I like the rod ends over a pointed rod in that the rod does not fall out if you forget to maintain it in compression, and in my case, the rod was...

Large Radius Turning

Here is another variation on a device for turning large radii - in this case 8", for a male and female die to contour 1/8" thick steel shims. The die blanks are made out of scrap oak laminated together. The radius can be set at any length by changing the piece of allthread in the connecting link. Th...

Re: Bolt Shear

As you note, bolts or pins are cheaper than the alternative. Our farm had a rock pile of a field and it was common to use several pins per tree hole. Went thought boxes of bolts but never messed up a gear box. Then there was clown we know who got tired of replacing bolts and installed a really high ...

Re: Hydrogen Embrittlement

Probably not an issue for that period of time. Also depends on the steel, harder ones are more susceptible. A night in a warm oven should help any hydrogen diffuse.

Re: Thread ending positon

The washers do not have to be thin - they can be a multiple of the thread pitch - just have to be different thicknesses.
