My Real Bull came fitted with a metric leadscrew, and for some reason had the imperial one as well. ? I’ve never had to use the imperial one, but shipping (I’m in Oz) would be a bit steep. ? Tony ? ?

Subject: Re: [7x12MiniLathe] CJ0618 lead screw? The CJ0618 is a Real bull lathe. If I remember right (don't quote me 100%) the Grizzly 7X mini is also. Take a look there. It's easy enough to tell a Sieg from a RB by the cross slide. The RB has the solid rectangular slide and the Seig has the "H" shaped one. Shipping from Arc is a bit expensive across the pond but in my experience they are very good to deal with so there's that.?

However, the shipping to the US is a bit expensive. I haven't been able to find these items on Amazon. eBay and AliExpress have the metric version but I cannot find imperial versions. Little Machine Shop has lead screws for Sieg 7x14 lathes, but I believe there are some differences that may cause problems.

Why are you considering replacing the lead screw?
?
There are numerous sites that provide comprehensive threading charts for either flavor lead screw; with 3-D printing, additional change gears are easily obtainable.? Actually, if you had access to an engine lathe, you could even make your own leadscrew ;-)

Roy Yes, it should be possible , on the paper. However, I have used my 7x16 in many years to make a Sterling machine, no one will start.
This Jupiter pencil sharpener was very popular for many, many years. A Beauty , and expensive tool. The cutting blade is still available on eBay. However, it is expensive. I managed to sharpen it, but it is not made for that. Johannes ? Lavoll. ? ? ? ? ? ? ?

I guess the next project will be a wood-fired steam engine to eliminate the hand cranking while disposing of the pencil shavings ;-)

"Mr. Pete" (Tubalcain) has been running a series on the early Unimats, and out of the blue somebody sent him a little cabinet with a backsplash that was ANGLED.

This seems to help greatly in opening up the space behind the lathe.? The notches are designed to hold tool holders, but you could make notches, or holes, for anything to get additional utility.? Or none at all.? You could make a top bend rearward and horizontal and put holes in it to hold centers and such.? The part here is stainless and must be pretty thick as he said it weight 10 lbs.

Re: Angled Backsplash Idea
I have a DRO on this machine, so the backsplash had to say goodbye.? I use a cookie sheet and a butchered cardboard box to catch the swarf.? It does keep the mess down.? When the box gets full, throw it out and put in a new one, LOL!

Re: Angled Backsplash Idea
I raised my mini lathe on 1 1/2 inch high blocks made from Trex and you could also use wood. The photo shows a slot I cut in the backsplash?lower surface. Other lathe photos and drawings available on request. Regards, John Mattis (retired mechanical engineer)

Re: Angled Backsplash Idea
I used a piece of scrap wood to move the splash plate about an inch farther away from the bed and bent some aluminum roof flashing to fill the resulting gap by the headstock.? There are no clearance issues and it keeps the mess under control and not on the wall, behind the stand, on the floor, etc.

Re: Angled Backsplash Idea
I removed my backsplash too, shortly after I got the lathe.? It was too annoying for me, and I don't want mounds of swarf collecting right there.? I let all the swarf get pushed off the back where it collects at the base of the wall.? Eventually I reach under the lathe stand to pull handfuls of swarf out, but really it never gets seen.? I often have the motor cover off too, because it prevents the carriage from getting up close to the spindle.

Re: Angled Backsplash Idea
When I found it getting in the way, I simply took it off & propped it against the wall behind the lathe.
