Re: HEIGHT Gauge question

50 years ago I was a newbe tool designer and the tools, mostly part holders with sensitive electrical connections, were built by very qualified tool and die makers. A good share of what I know about machining was learned by watching them. Every granite table they used had one of those gauges on it. ...

Re: Dog Lover Lament

I ended up with a hybrid Black Lab that had been bought from an expensive CA kennel that deliberately bread dogs to correct some of the faults in the pure breeds. This one lived to 18 years, had no hip displasia and stayed as thin as a 2 year old lab. Further it was wonderful with people, even stran...

Re: Ceiling tile for my shop

I had a similar garage in upstate NY, It gets very cold in that area do I wanted a lot if insulation with minimal labor. I put 24" wide by 6" bats between the trusses, squeezing them close together. Then to add something to hold them up I put up 4x8 sheets of OS B. To get rid of the problem of edges...

Re: Never enough time

I have recessed ceiling lights and I replaced them with dim-able LED bulbs. In Vt that is an automatic as the state somehow subsidizes LED bulbs so they cost less than incandescent bulbs. They worked fine gave perfect colored light but the dimmer stopped working. The lights would be either full on, ...

Re: Flail Mowers?

I'm interested in the roller part; ... So TomB, you seem to be saying the roller didn't have a deleterious effect on cutting performance, on rough material at least? ... The roller was behind the flail such that the grass and weeds went through the flail and then the cut grass was rolled flat. In o...

Re: Flail Mowers?

The ski mountain I use to own required a Flail mower. There was no other choice. When were mowing with brush hogs we would go through 3 machines a year where each died from bent blades, shattered housings and broken drive shaft ends. I did not mow or maintain, just paid the crew and bought new machi...

Re: 5C Collet Racks from the Tormach

What supports the weight of the collets? I could guess they sit on the drawer bottom or on the holder board. A big rack of collets like that is heavy so they tend to bow a thin wood part if it not supported well.

Happily never happens on this forum. Having come from an industry where computers were extensively used I'...

Working on my house -- ever try driving a nail in it?
I lived in a house like that but I was always told the nail proof rafters and studs were Eastern Hemlock. Maybe the phrase should be "Harder than age dried Hemlock."

Re: It's been a long, long, long time!!

Welcome back. I followed your posts many years ago but had no inkling why you had to leave. Like you I raised a granddaughter but at the same time had to help her father grow into adulthood. She is now 27 and has two wonderful daughters. She dotes on them so carefully that I know I or her father can...

Re: Geometry Puzzle

The pieces are not in the same arrangement Note that the two step pieces in the first image make a solid rectangle. Then the height of that rectangle is less that what is being perceived in the second arrangement. To make the triangles line up switch them. This makes the smaller triangle's height ma...

Re: automotive oscilloscopes

To bring my old experience up to date as a DYI project one would have to connect the inductive probe to an AD converter in the smart phone, assuming it had an adequate sampling rate and sufficient sensitivity. I know of no way to measure the voltage developed by the sensor other than hooking it up t...
