Good job mike, it looks quite happy in it's new digs.

Darned nice looking lathe, that would be a very nice feeling to finally see her sitting in it's place.
(Don't forget to put the drawers back in before you fire it up!! Lol )

I had a reply almost finished when my browser shut down. Arrgh!
The drawers are in place. I got the wiring run after work today. Mapped the six spindle speeds - 55 to 505 RPM. Later, I got curious and checked. There is a second set of pulleys from the motor to the gearbox. I'll map the other six tomorrow.
I was running through all the settings on the QCGB when the output shafts stopped turning, even though the final gear was still turning. I found that the woodruff key was missing. I'll buy or make one on the weekend.
Let the playing begin! If I can find 10 tpi on the QCGB, I'll make a new handle for the back gears. The original obviously got broken or lost. It was replaced with a length of 3/4" x 10 threaded rod. Have to make a thread dial at some point, too.

At some point, the handle for the back gears either got lost or broken. The original owner replaced it with a piece of 3/4" x 10 threaded rod. Functional, but ugly as a mud wall.

I did a lot of test cuts to find out if I could cut 10 tpi with the metric setup on this lathe. In the long run, I may have to replace the 127-tooth gear with a 100. Just guessing.

I did find one setting that gave me 10 tpi. There was a really interesting threading tool in the stuff I got with the lathe. Intricately shaped blade set in the holder, with a screw to adjust the vertical position of the cutter. Grind the top edge to sharpen the cutter.

The toolpost on this lathe is quite different than I'm used to. The domed section has a large pocket nearly 2" in diameter that fits over a matching shaft that is machined out of the same piece of steel as the top of the compound. The shaft is slotted into four parts. When the bolt is tightened, the four parts expand inside the pocket, like an inside collet. It holds very firmly. The slot that clamps the toolholder has a rocker in the bottom. The two clamp bolts make for a very rigid installation.

I was planning on getting a QCTP this weekend, since the 'right' size is on sale right now. Two things stopped me. The integral shaft on top of the compoud and the distance from the top of the compound to the spindle centre line. It is only about 1 3/8" from the top of the compound to the centre.
I just smoothed off the new handle for now. As with all new machines, there will be a long list of accessories to make. A radius cutter is on the list. When it's finished, I may add some shape to the handle.

Nice pics Mike , looking good.

Thats a neat threading tool design, kind of like a tangential tool holder.
RE: Storebro 15 x 36 Lathe (I think) - dallen - 12-09-2013
aloris makes one on the same design, grind the top to sharpen and adjust up to set center, only problem is I can't afford what they want for one.

That's what I thought when I first saw it, but the top cutting edge ends up level when it's adjusted to centre of work.

Mike,
Looking good

I really like the look of that lathe, I'd be interested to hear what you think about it after you have had a chance to use it a bit. Hard to beleive a lathe owner would use a threaded rod to fix something like a handle? He should have been ashamed of himself
