The Japanese was buying American before Dec 7 1941. This just sharing a machine tool photo

I have a nice Jacob chuck buy does not take small drill and do not want modify the one on drill press. So purchased one Walmart.

I made a knurld ring on my brass knob. but, as the result, something wrong with the knurld surface. it's not even crossing each other. How can i solve this ? i turned on my lathe with 240 RPM and fed with my hand.

Last week, I changed the undersized, crappy radiator in my kitchen for a bigger one that heats the room much better. This involved undoing big threaded components that may not have been touched in half a century. A tool that to some extent made the job possible was a 24" Crescent wrench I bought from Harbor Freight. It cost $33, which I thought was very reasonable considering the size. Here's a picture of my newly installed and painted radiator with the giant wrench on top of it. It may have been possible to get this plumbing apart with a small wrench and a cheater bar, but it wouldn't have been EASY, which it was with this wrench. (Also, taking heating equipment apart in the wintertime is a bit risky because if you screw up, the house may be cold for a long time). I can't say any of us will ever find something on a minilathe that needs a wrench this big, but I'll find other occasions to use it, and I bet you would too. Mike Taglieri

Here photo from How to Run a Lathe It shows two ways of threading. I have used both to me they work same.

Looking for photo and drawings on Flame / Candle Engine. My next project wis going to a flame ? engine and looking for data. Dave

I need to broach some keyways in gears for my lathe but need to make some guides. What is the width of the slots for type A and B guides?

Hi I want to meet Mexican users of 7 x 12 mini-lathe. I live in México City, however,I don't speak Spanish. ;) First of all I need info where to go to get metal. /johannes

I just bought a Shars 6" dial caliper after admiring one belonging to a friend. It's probably the best and most durable dial caliper I've ever had. But I also have a Chinese dial caliper that's cheap and less solid-feeling than the Shars. So would it be practical to turn this cheapo dial caliper into the equivalent of a DRO to measure tailstock extension? This would have disadvantages compared with using a digital caliper for this, because you can't change from metric to Imperial and you couldn't hit a button to zero it. But a major advantage is that the batteries would never die. Has anybody tried this?

I have wanted a mini lathe for years to do small metal turnings around the house, things like thread cutting, radio knobs, shaft couplers, etc. I thought I could just go get a Harbor Freight lathe but I keep reading stuff about having to redo lathes even after you buy them. What's the best lathe that I can get for $1,000, one that I don't have to rebuild before I start using it? Should I spring for over $1,000 and get a Grizzly?

Am I crazy? Too big for my 7x16? I need just to cut/grind/polish the outer surface so it looks nice. I think it has been a 2” axel , see the key slot. Weight 3.5 kg. High carbon steel ? I cut it with an angle grinder: the sparks had a star in the end. Johannes Lavoll.

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.
