I have just begun trying to turn pens. Bought a (new to me) used lathe and tools. Am turning the first pen using cocobolo blanks which were included in a kit bundle from PSI. So far I've spent about 4-5 hours turning this pen. To me, this is an outrageous amount of time for turning. But maybe it's unrealistic to think the time should be less. I have to believe either my technique is terrible or the lathe tools I have need to be sharpened. I've tried sharpening them a bit, but how sharp is sharp? In other words, how sharp do they need to be? I've tried using mostly the gouge and skew but neither seems to be very effective. The cutting area of the tools is about the centerline of the pen blank.
Can anyone offer any suggestions or tips? How long is reasonable to turn the pen on the lathe?
Thanks for any help.
First, welcome to the forum!
The gouge and skew are good tools to use for pen turning. Like others have said, they do need to be sharp. What do you have for sharpening? Grinder? hones? Sandpaper and a chunk of hardwood? (Yes, I have used that to sharpen my skew and it worked better than I thought).
Cocobolo is a pretty hard wood, but I wouldn't think it'd need that much time on the lathe. With prep time (including waiting for epoxy to dry), I could see it taking a couple hours for that and not a whole lot of time on the lathe.
When I started turning pens a couple years ago, it would take 2-3 hours for the whole thing: cutting, drilling, gluing, trimming, turning, finishing. It still can take that long, but I spread things out now, usually doing the prep work one day, and the turning and finishing another day.
One of the things that helped me quite a bit was running the lathe faster. I have turned quite a few bowls and start those out slow due to their size, speeding the lathe up after getting things round and balanced. With pens, you can start faster since the diameter is a lot smaller than a bowl. I'll regularly start with my lathe around 1600 RPM to knock off corners and then it's up to 2600 or so for shaping. I'll drop it down to the slowest speed for sanding so as to lessen the amount of heat generated (some material does not like heat and will get even with you if you get things too hot).
Anyway, I hope this helps. If that pen keeps giving you trouble, keep asking. I've found the people here very willing to share knowledge. Sometimes even slightest mention of something in a "Hey, I need some help" type thread can solve a problem that's been vexing me for months.
