If he would concentrate all his efforts on just one thing like cars instead of trying to reinvent the world, he might just be competitive with GM, Ford and Chrysler.
Actually, GM, Ford, and Chrysler are the ones that can't compete with Tesla!

Re: Mirroring a part

I usually just plow ahead and make the mistakes so I know the answers for later... I have mirrored parts before, but as you have already done, I draw it accordingly, and just flip the CAD drawing and generate new code. I always drip feed the machine anyway. I'm kind of curious to try the "mirror" fu...

Re: Mirroring a part

I've never tried the "Mirror" function on my controller, but I'm curious if the location of the "part zero" comes into play as it does in CAD.

I forgot to root through the manual last night to see what is involved.

Re: TIG Welder - Everlast

Does it not strike you as odd that the motherboard for the Miller Dynasty costs $800 when you can buy a complete 200A TIG welder, albeit with poorer specs and not quite as many features that you are unlikely to use, for $150? https://www.ebay.com/itm/MMA-TIG-ARC-IGBT-Welding-Machine-200-AMP-110-220...

Which still doesn't explain the odd designation.

A 55° BSW thread angle is fairly obvious.

Could the 1/32 be the Whitworth number?

Whitworth has weird inexplicable [to me] numbering, and this seems to be a size from that place and era.
The designation would be 1/2 BSW.

Re: 1/2 - 12 tap

I wonder if Greenfield customer service knows and would answer the question. Just make sure you ask to speak to the person that has worked there the longest! I bought a piece of equipment that wasn't too old and called the manufacturer to ask a question about it. A woman answered and knew all about...

Re: 1/2 - 12 tap

The 12 TPI tapered taps I mentioned were described as 3/4" and 1-1/4" .taper per foot, so I didn't see any obvious correlation between that and the "1/32". 1/2"-12 used to be a fairly common thread a long time ago, but is pretty much obsolete these days. Taps certainly aren't rare as many suppliers ...

Re: 1/2 - 12 tap

That is interesting...

I quickly rooted through my "Seventh Edition American Machinists Handbook", but nothing jumped out at me.

There were some locomotive and boiler taps that were 12 TPI, but they were tapered threads.

Didn't have much time to noodle with it right now though.

Re: TIG Welder - Everlast

Speaking of not being a fan of the "replaceable era" we are in: I started looking at new inverter welders when Steve started asking about them. I figured I owed it to myself to get one since I enjoy TIG welding and bought my present welder, used, 46 years ago. I for sure wasn't impressed with digita...

I'm curious as to why you had concerns about the carbide end mill. I find them to be much sharper and provide a much better finish than HSS end mills.
