Nicely done lad 😁 im about to make some trees and snowmen as late Xmas gifts, ive been busy helpin me Dad set up things in his workshop, metal lathe etc. so i havent had time to be at my lathe. Maybe ya already know, and what il say is for nothin..... But il blabber on anyways 😂 Your first tenon was a bit small...... But ya know this as ya used a different piece for the video. The jaws are machined round at the factory, then cut into 4 parts, this cutting creates a kerf....... The jaws dont make a round shape when fully closed, its only grippin on 4 little sections in the middle of the jaws. When shaping the tree, you were gettin little catches/kicks....... This is because too much of the edge (or the wrong part of the edge) was in contact with the work. Its hard to see from the video, if your skew was flat on the rest or tilted up on edge slightly. If flat; ya got the catches because too much of the edge was in contact, we only want about 1/3rd of the edge cuttin while doing a peelin cut like this, any more and the tool will protest, its jus too wide of a cut. If the skew was tilted up; then the side that was tilted upwards came into contact. When this touches the work it has no support, on that side of the tool theres only fresh air under it...... When it touches the spinnin work, the wood grabs it and slaps it down against the rest. We want to cut with the lower 1/3rd of the tool when makin this cut. I like the way ya used the width of your tool as a gauge for where to make the cuts keepin it even, instead of measuring. I also like the way ya used the side of the skews bevel as a scraper on the end grain sections as ya were makin your cuts, saves time cleaning that surface, you done it all in one process. With more time you wont be wary about the speed, it seemed to be spinnin quite slowly and your tools werent very happy sometimes. There is a formula of sorts...... RPM X Diameter (in inches) = 6000-9000. So a 3inch diameter part should be spun from 2000-3000 rpms, 12inch diameter part spun from 500-750....... I dont always follow this, i usually turn the lathe up til it shakes/vibrates, then back a little til it goes away. So long as your fixing to the lathe is good, and the wood is sound; speed makes all the difference, the wood likes it better, the tools cut much better...... just make sure there are no splits/cracks in your blank. But; always work within your comfort zone....... Dony ramp the lathe up into the heavens coz some randomer (me) on UA-cam said so 😂 Happy Christmas lad, hope ya have a good one 😁
Those are nice Christmas trees you made 👍
Thank you!
