Home Machine Shop Tool Making - Machining A Small Lathe Carrier

Home Machine Shop Toolmaking, Machining A Small Lathe Carrier, by Clickspring. Clock pillars are an awkward little part to hold and machine, once the tapered and curved sections have been formed. Its best to hold them by the small spigot, to avoid marking the part. A standard lathe carrier is not suited to the job. In this episode, I machine a custom lathe carrier to suit the task. A great mini mill project, with some marking out, mill work, the belt sander and hand finishing. Be sure to use breathing protection whenever using a belt sander.

I saw a picture in a John Wilding book, of a carrier that will do the job. He calls it an "antique lathe carrier" https://www.seevid.ir/fa/w/zB9XhqzBNJs The thinned down section will grip short cylinders like the spigot, but still keep clear of the center and the thicker cross section at the outside can be drilled and tapped for a decent sized cap screw. https://www.seevid.ir/fa/w/zB9XhqzBNJs Actually I spent quite a bit of time thinking about how I was going to make this part, and eventually I figured it was probably best to start with the central hole, and then work on the perimeter. It took a bit of thought to come up with a sequence where I could make the cuts that I wanted, and still hold and locate the part https://www.seevid.ir/fa/w/zB9XhqzBNJs Then I milled away most of the waste stock from the perimeter so that I ended up with 2 flat surfaces on either side of the curve. My plan was to use those as a reference surface to locate the part horizontally in the vise later on in the process. https://www.seevid.ir/fa/w/zB9XhqzBNJs And you can see that I've left it quite a bit short of the line, mainly to give me a bit of metal to work with when I'm doing the final finishing. So with the bulk of the metal removed, I can get the curves into shape and I did that with the bench filer and the belt sander. https://www.seevid.ir/fa/w/zB9XhqzBNJs This one was a bit blunt and not quite long enough. So I had to nurse things along a bit to avoid chatter. I ended up with a bit more chatter than I was happy with towards the end of the cut. So I tried plunging down at full depth, and that seemed to do the job. https://www.seevid.ir/fa/w/zB9XhqzBNJs For the other side, I figured the plunge cuts worked so well, lets do that again, except this time it didn't work so well. There wasn't a huge amount of chatter and I was planning on hand finishing the surfaces anyway, but there you go; no more using blunt tools. https://www.seevid.ir/fa/w/zB9XhqzBNJs It worked out ok, but the cuts were slightly off. Luckily I had enough material to tidy up by hand so it didn't matter. So first up a bit of belt sander time to tidy up that saw cut; and I don't need those reference surfaces anymore so they can be taken to the line too. https://www.seevid.ir/fa/w/zB9XhqzBNJs There's a few fancy end curves to put in and just a little bit of filing and sanding, to take off the rough edges and give it a presentable surface finish. https://www.seevid.ir/fa/w/zB9XhqzBNJs Its still got to look good, at least until it gets all banged up. I softened the edges a bit too, some of those were still a bit sharp, and want them completely dull. https://www.seevid.ir/fa/w/zB9XhqzBNJs And here it is about to do its first job. I'm glad I finally got around to making this. 1/4" seems to be a standard size for pillar spigots so with a bit of luck you'll see this carrier pop up in plenty of future video's References: John Wilding picture of an Antique Lathe Carrier "Tools For The Clockmaker And Repairer Part 2" pg 27 http://www.ritetimepublishing.com/ Music: "Pilot Error" - Kevin Macleod - http://incompetech.com/music/ Home Machine Shop Toolmaking, Machining A Small Lathe Carrier, by Clickspring.
