OT Texas Tesla crash

I would also like to see some pictures of the setup which is causing the problems. Overhang of the boring bar is the most likely, and when I use a boring...

I am sure that fine work can be done in difficult conditions, as long as the machinist is aware of the limitations of his machinery. Smaller cuts and...

6 minutes of angle can be a lot when machining, it is 0.017" in every 10".

If you use carbide inserts, then the ones designed for stainless are sharper than for steel, and those for aluminium are as sharp as HSS. The aluminium...

Doe's the spline profile equate to a gear profile? The gearbox shafts and gears in the Villiers Starmaker engine were advertised as involute splined,...

I'm sure that a huge ammount of research is being done to make electric vehicles safer and also into the consequences of the unavoidable crashes and breakdowns....

What a beauty, it would be a 53 cube, or 875cc.

I modified spanners to make sure the collet was tightened properly in the mill spindle, they are 12" long. If you loosen the collet when it is in...

As many of the milling attachments for lathes, that one looks about as stiff as a wet noodle.

I was mystified as to the circumstances regarding the driverless Tesla in which two people died. Fortunately, it was a single vehicle accident, but what...

I have added them to my list of websites, just in case. I wonder if they will deal with the small customer, some don't.

I wish Kawasaki still made keyless chucks, they work in reverse too. I got rid of a newish Albrecht, it does not compare well.

In the UK, NOS Jacobs chucks come on the market from time to time, I have been lucky with UK and USA made ones. I would avoid the new ones, their reputation...

Shame about the milling attachment, I know what they are like, I still have the one for my 7X12 and only used it once. The length of the modified tool...

Looks a bit dodgy to me, how about a slot along 1/3 length of the one lying down on the plate, then it can be adjusted for radius and the lower profile...

I know the feeling, we are refurbishing an Atlas 12 x 24 and one of the chucks that came with it was scrap. The backplate had possibilities and I bought...

The learning experience was worth a dozen spindles bought in a shop. The more you do, the more confidence you will have to take on projects. Making scrap...

Those blocks work quite well enough for our purposes, I rarely need to go below +-0.001". I do have some other standards which are in better condition...
