Maintain Your Lathe's Tailstock to Drill Accurate Holes
Вставка

- Tailstock maintenance is easily overlooked and poor performance isn't noticed until you try to drill or bore an accurate hole in wood with various types of bits. Off-center drilling or oversized holes can be a headache to try and troubleshoot. I know. I've been there. Here are a few tips that can get your lathe to accurately bore the correct size hole the first time.
List of some tools used in the video are available on my website:

It's probably not intentional, but I love how you somehow made this video feel like it came from a DVD course from the 90s or early 2000s.
Very helpful. I like your style. Very easy to listen and follow.Thank you.
Brilliant video. Thank you for sharing your knowledge. It has solved my problems drilling a straight hole. Much appreciated!
Glad it helped. Good luck with your woodturning projects.
My tail stock on a Nova DVR-XP got very tight, but a good clean up and removal of the hardened grease on the ram and threads restored it to free running again! Thanks!
You're welcome. Glad I could help. It's always the small things that create huge problems!
You are a great teacher. Thank you for this great and thorough video.
You are most welcome!
Wow, Thank you. Just what I was looking for. Just starting.
Welcome to woodturning. Careful...It's addicting!
Excellent, thank you!
Appreciate your deliberate detailed delivery. Many things learned from this. I'm new to turning and the basics are important for understanding why or why something did not turn out correctly. Thanks. new subscriber
Hi Timothy. I'm glad the video helped you. You can also read the article on my blog at: sokolowskistudios.com/maintain-tailstock-lathe-drill-accurate-holes/
It's sometimes helpful to have a printed copy at the lathe for reference. Good luck with your new hobby...it's addictive!
Great info.. thank-you. What's the brand of the carbide forstner bit in blue? Do they work best for long drilling these peppermils in end grain? Thanks again.
I love these carbide bits. So much better than standard forstner bits. You can get complete sets here: sokolowskistudios.com/shop/carbide-forstner-sets/
or if you just need a set for peppermills you can order the peppermill bit kit here: sokolowskistudios.com/shop/forstner-peppermill-bitkit/
They last longer and yes, you can sharpen them with diamond bits in a dremel tool or diamond files: sokolowskistudios.com/shop/diamond-file-set/
Hi Ted! Thank you very much for this video. This is very informative and the timing couldn't be better for my near future project. I have some experience in wood working but haven't gotten into this type of work with lathes. I want to start making Native American Flutes and I can't figure out what the best method is to bore the long piece. I am hoping the lathe would be the way but centering the hole seems to be very tricky when talking about a 28 inch long hole. Any suggestions? Any help would be greatly appreciated.
I would mount a piece of wood three times the final diameter you intend for the flute between centers on your lathe. Rough it round first with a tenon on one end then mount the tenon in a scroll chuck. Support the long spindle in a steady rest, dimple the center to start the drilling process on center then drill out the flute slowly using a carbide forstner bit. Add extensions to the forstner bit as needed to get to your final depth. Then remove the piece from the scroll chuck and cut the tenon off so that you end up with a long "tube". Mount the "tube" between a homemade dead center in the headstock and live center in the tailstock and finish turning the outside to the final diameter. Good luck.
@@TedSokolowski Thanks for the response Ted. I've seen this procedure done with full tubes like you mention. The one thing is that a Native American flute is not a tube. It actually has 2 chambers. It will be hard to get each hole from each side to align properly. I believe some makers use a big metal lathe to do this. It seems those are more precise, but that's a piece of equipment that is way out of my league at this point. I'll keep doing research. Thanks a lot...
I have vertical misalignment between my headstock and tailstock... The tailstock sits below the headstock center. This is temporarily remedied with shims made from copy paper... Brass shim stock would likely work as well. If you extend the ends of your shims out from under the tailstock and bend them up against it they will stay in place when moving the tailstock back and forth.
Shims will work if the Tailstock was machined incorrectly. (This scenario would be a manufacturing defect.) Hopefully, the shims you added will make the tailstock parallel to the ways of the bed consistently over the entire length of the bed. Chances are the misalignment is due to wear in the ways of the bed. On older, worn-out lathes, the bed may develop a slight belly near the headstock and it is usually a tapered belly. In this case, shims will not fix the misalignment over the length of the bed...only at the point where the shims align the tailstock to the headstock.. Sliding the tailstock (with shims added) away from the headstock will then raise the alignment. Machining (surface grinding) the ways of the bed is the only way I know of fixing this issue.
How do you drill a hole longer than your forstner bit?
You can use a Forstner Bit Extender. They run about $8 to $10. You can also reverse mount and drill from the other side. I'm doing that now with a lamp project and I'm also making three separate parts for the lamp that will glue together using tenons to increase drilling depth.
@@tedsokolowski4016 Luv it. Cant wait to see that.
@@klabackam Hi Mathew. I finished that lamp project I talked about. I decided to write an article showing how to extend the depth of drilling a hole longer than your forstner bit. It features the lamp. Have a look: sokolowskistudios.com/blog/
