The Home Machinist!

It appears the Jacobs model 50 uses series 500 collets. These have protruding outer jaws. My stuff is 900 series and the ranges are similar but the collet dimensions probably aren't. I roughly measured the length, OD of the widest tapered jaws and OD of the smallest part of the tapered jaws. I used ...

I haven't yet owned them but see they are useful. Straight parallels are very thin and in setting up, tend to tip. I would select a spring to locate them against the jaws. The wavy ones seem to have an advantage there. Also when milling atop a fixed part, there is more support.

If we look at the construction of one wagon wheel of 150 years ago; There is a certain hub which was old hard elm with wavy grains which wouldn't split. The spokes were different for pressure and the rims something else when banded. Each wood has its own characteristics and they knew how to put them...

There was certain wood for every use and how another wood fit with it. They have their different grains and wear factors. This is a big subject but now I say stick with metal when using metalworking machines.

Mine isn't exactly yours but I have read there are hidden screws or clips. At this point, you may inspect, lube and reset the pre load of those rather large bearings. The bull pulley has an oil port accessed by a screw between some Vee and it will line up with another-but- this may be different. If ...

Anyway. It is a thing which you don't want to take head off just now. Plenty of water now but who knows about next year's drought. Stick a little wire flag pole next to it, so don't mow it down.

I'm a wanderer off a distinctly good thread here. Mr. Atunguyd, salute to you and your son. These are the times where he really learns and has a jump start over conceiving without actually knowing how to get there.

Well, far as I know Fein was the first. The patent expired or anyway, everyone got into making copies. Hospital use was cutting casts off. I had to believe how neat that was. These are great tools because they work differently than any other. I did the same thing Steve G did some years ago. I had cr...

I regret my earlier post about blue dye. I've never used "dye" but Prussian Blue and Dykem. So the post was based on neither directly and falls into the category of rhetorical hyperbole.

One area of my basement shop had similar treatment. I don't remember why that can of white paint was sitting there. I was actually cleaning and that can hit some object on the floor. It started spewing paint everywhere. Got white stripes across machine bases, tooling, etc.

I just use the blue in smaller tubes. It does separate over time or temperature extremes. I try to knead it, remix it. It is tempting to remove the cap but that isn't air in there. It is a chemical component of the mixture which vaporized.

Really good recent information. Thanks Ed.
