Re: Grizzly is doing better - I hope!!!
The good old days are a distant memory.?
I have had them reject coupons in the store so I don't ask anymore. If your store will let you use it, go for it, but mine won't.

Re: Chris from Clickspring just dropped an new Antikyhera fragment video
The channel (with way way more videos) is found here:
The video was absolutely mesmerizing,?showing the construction of a primitive lathe using just hand?tools. (Even Dave Gingery had feeler gauges, rulers and other precision devices for his homemade shop, but this guy doesn't even have those).?
As he says, this primitive lathe is rather like a watchmaker's turns, the precursor to a watchmaker's lathe and still preferred by some watchmakers today.? The video shows turning between centers, which nowadays is hardly ever used today, even though it's the only way to repeatedly remove and replace the work in a lathe without losing precision alignment.
But I'm wondering, if this is video #11 in a series, where are 1-10?? Not everybody would have the patience to watch them?all, but he should at least tell us how we can.

Re: LMS Hand Wheel X/Y DROs
Thanks, y¡¯all!
I was calibrating my TouchDRO app using a new Dial Indicator and using the 10yr-old LMS X-axis rotary encoder DRO and wondering which to believe! I think I¡¯m able to trust my newly installed LMS-supplied magnetic scales now. I¡¯m a bit disappointed that the BT adapter they supply with their SIEG scales/readers is not Yuriy¡¯s and will be trying to get the scales/readers to work with Yuriy¡¯s adapter by adding some extra electronic hardware.

Re: LMS Hand Wheel X/Y DROs
Hi, Bret; as Brian noted, you still need to take backlash into account, which is one reason I added the iGaging scaled to my 7x16. They can also slip/skip if you turn the hand wheels too fast (most easily seen when withdrawing the tailstock).
I had some significant issues with the ones I bought 3 years ago, but LMS worked with me getting (slightly) revised heads with better QC out to me. I also made modifications to mine eliminating metal-to-plastic contact between the rotating & stationary internals.
Happy New Year, Charlie

Re: Grizzly is doing better - I hope!!!
Not like thd goid old days.??
The good news for a purchase a new mini lathe in November for $589.00 . Now I do not feel bad it is still $799.00
thank you

Re: Grizzly is doing better - I hope!!!
Harbor Freight is just concluding a 4-day sale today , and has a 25% off coupon.? That's how I bought my initial lathe (before modification) and my mini-mill.

Re: Grizzly is doing better - I hope!!!
When first look at mini lathes about 20 years ago the was about $250 to $500
They look good for little projects.??
I switch to mini lathe for size and weight.?
I did find the lathe was? good with few miner fixes. The biggest wast a good tool post.?
As far as Grizzly does they make a nice lathe with price to match. I typically can find a better price from Amazon,? Harbor Freight,? Walmart and Ebay. But know looking what for Grizzly take gust work out .

Re: LMS Hand Wheel X/Y DROs
They sense the rotation of the screw, not taking backlash between the screw and nut into account. No better than the markings on the dials.

Re: DC power supply grounding
Appreciate everyone's thoughts.
On the diagram I posted, that emergency switch has traditional spade connectors. So one easy fix is to just swap the white and black connectors, putting the fuse on the hot leg. That puts the potentiometer switch on the neutral, which I guess isn't all that big a deal.
However, I plan on keeping the orientation of the two wires to the emergency switch and moving the fuse (breaker) to the hot side anyhow as it just makes more sense to me. Will revise the diagram for my needs going forward and stick a copy in the control box so I can't loose it.

Re: Grizzly is doing better - I hope!!!
OK, let's be clear.? ?These 7x lathes have a very wide price spread, with no discernible difference in quality except to a lucky few that received a really good one, or alternatively meets their particular accuracy requirements.? ? Even the brushless motor, initially only seen on LMS and MM lathes, is available from lower priced vendors on amazon and ebay.? ?Any price variation is only at the discretion and desired profit of vendors.
And what is the point of the paragraph above?? ? That there is substantial room in the prices of the "premium" vendors to require better factory setup, not just luck of the draw like every lower price vendor's machines.
And even for all vendors, the factory could do better.
There is one specific improvement that would not make for a large price increase and would be easily accomplished at the factory level.? ?And that is headstock alignment which is the most critical parameter for accuracy of many operations.? ?Extra time at this point when the lathe bed and headstock (with spindle installed) are mated would made a big difference in the performance and accuracy of the machine.? ? This is the single point that requires more QC, notwithstanding my experiences with mechanically seizures on run-in or DOA electronics.
All other deficiencies are secondary and much easier to correct or live with.
