Re: $1000 Budget: Which 7 x 14 to buy?
I am just using the dials that came with my Speedway lathe that I bought 20 years ago. I have a 1-inch travel dial indicator that can be moved along the bed and a stop for the carriage that is adjustable. You do need a way to clamp the carriage when making facing cuts. I always manually feed toward the headstock and power feed toward?the tailstock to get a better finish. The compound should be set to 29.5 degrees.

A lot of care! Wish I had one of these instead of a mini-lathe! Mike Taglieri? On Mon, Feb 19, 2024, 8:59 AM WAM <ajawam2@...> wrote: |
Re: LittleMachines DROs and dials
Peter Way 10:40am? ? Edited 10:41am I have a Littlemachines lathe with really awful DROs. They use V389 batteries that last about a minute. I have the following questions: 1. I'm working on a 3D printed battery holder that allows a AAA battery instead. Is anyone else interested in theseBad news You buy AAA battery holders from Amazon and Walmart for under package of 4 to 6 $10.00. Some have a on off switch? |
Re: LittleMachines DROs and dials
They had some like for BP mills in the 1960's.?
They did nothing for screw wear in center or nut wear.? FYI If try adjusting nut wear it would not work because of screw wear.? Next travel dial They like to skip.? I think travel dial could work with a using a rake . I use dial indicators. I have one 2" stroke most time I use 1" stroke works.? On the mark every time. Dave? |
Re: Variable speed motors
I have one of his motor/controller running my MicroMark 7x16. The original motor died...feels like one of the magnets dropped out of position. I selected his bare-bones 900W version. Fairly easy to install. I needed to move four holes on the lathe's mounting plate, thank the Lord for the DRO on my mill.? I also had to enlarge the hole on the lower pulley.? That was a challenge reaming it by hand using the un-powered lathe.? Here's a picture of my setup.

LittleMachines DROs and dials
I have a Littlemachines lathe with really awful DROs.? ?They use V389 batteries that last about a minute.? ?I have the following questions:
1. I'm working on a 3D printed battery holder that allows a AAA battery instead.? Is anyone else interested in these? 2. As I researched this, I realized that some of you have found linear DROs that may even be better to position the carriage and cross slide. Can you recommend the best option?? It looks like magnetic ones are good for this application, and some cheap Chinese ones are really capacitive, and not as good.?? 3. Have any of you converted from DROs to old fashioned dial handles?? That would be nice in addition, since those don't require any batteries, etc.? I kick myself every time I think about having bought the DRO version. |
Re: making Colchester Lathes
I think many on this list already know this, but when they say a "5 inch" lathe in the video that refers to the radius that will clear the bed.? Some parts of the world use radius.? Others, such as in the U.S., use diameter.? So, the mini lathe might be 7 inch swing (diameter) or 3 1/2 inch swing (radius) depending on where you are. Charles E. "Chuck" Kinzer

¿ªÔÆÌåÓýSorry to bump an older thread but in doing some research on the
controller board used in the sewing machine motor kit I had
purchased I found the following site. Please note that I have no affiliation to this site nor have any
experience with his products, but he seems to offer a full line of
conversion kits and parts for these motors. This includes full
kits for the mini-lathes and mini-mils along with a ton of other
machines.? It also appears he does some repair services as well. -Jay On 2/9/24 21:45, Tony Smith wrote:
