Newbie question

[Matt Day]

I bought my lathe a few months ago but just started to play with it due to some other projects and life getting in the way. At any rate, I'm starting small and enjoying it; it's very different from flat work!

My simple question is about tool choice and technique. I need to turn a 1/2" diameter dowel on the end of a piece to insert into a 1/2" hole in another piece. The dowel needs to be about 3/4" long, and the end of the dowel will be exposed so I'd like a tight joint. What's the best way to go making a consistent diameter dowel to make a tight fitting joint?

I've tried using my diamond parting tool since it has a flat face, but I doubt this is the best way.

I have basic set of Benjamin's Best lathe tools.

Thanks in advance!

welcome to the turning thing. i'm fairly new, too, but the two things that immediately come to my mind are a good set of calipers, and a skew gouge (which can be a tricky tool for a new turner to use well) - that should make a nice, flat surface on the 'tenon' - post a photo or two when you're done. mike

Matt, you can use a smaller, 1/2" or smaller skew or a square ended scraper. Anything with a straight cutting surface will help you get a consistent diameter on your dowel or tenon. As for measuring, I use a 1/2" open wrench. It's pretty close to exactly 1/2", maybe slightly larger for a good tight fit and it has a wide surface so you can check the consitency of the diameter. In fact for fitting most things like that I drill with a forstner bit and use the corresponding end wrench for the tenon. Remember when turning a dowel or tenon that it takes just a smidgeon of a cut to make it too small. Sometimes sanding is all it takes.

Matt,

Welcome to the Vortex!

You could use a parting tool, a square end scraper or a skew.

If you use the parting tool, make sure it is sharp and use a peeling cut. Get the end of the dowel turned to the correct diameter and the work your way back to 3/4" length.

Matt,
Ken beat me toit. Was going to say- turn about 1/8" to the correct size and then turn the additional length needed. If you get the first 1/8" a bit too small, you can just turn it off and try again. Careful not to make it too tight, as wood movement could cause the piece with the 1/2" hole to split.
