How To Make A Clock In The Home Machine Shop, Part 10, by Clickspring.

The chapter ring gets a little extra bling in this episode, with the addition of an ornamental bezel.

Plenty of lathe and milling operations in this video, as well as some of my favourite activity at the moment: hand turning with a graver.

Thanks for watching. If you enjoyed the video please give a thumbs up, and leave me a comment.

I’d like the outer bezel to dominate visually, so I’m going to give it an ornamental pattern.<br /> 0:00:42 The real challenge for this part is simply holding onto it to make the cuts, and if you’ve been watching the previous videos in this series, you won’t be surprised to see me reaching for another super glue arbor. I’ve sized this arbor to give me access to the front and perimeter of the part, and to also allow me to make a trepanning cut in the center which I’ll show you in a moment.<br /> 0:01:03 Once the blank was fixed in place, I trimmed the perimeter to size. Then I made the trepanning cut to remove the stock from the center. This slug of brass will make an excellent great wheel on a future clock. The inside diameter was brought to dimension, and then I formed the recess to accept the chapter ring.<br /> 0:01:58 At this point I’m giving it a very slight back taper, for a snap fit with the chapter ring, and good undercut for a close seating. I’ve machined a register on a second arbor to be a close fit in that recess. This arbor will then hold the part from the other side, so that I can machine the other face.<br /> 0:02:38 The fit with the register is nice and close; all it needs is a small amount of superglue to hold it in place.<br /> 0:02:51 I want the ornamental cuts to be precisely the same depth around the entire piece. The work was then set up on the mill to form the pattern. I’m using a rotary table for indexing, and I’m making the cut with this shop made D bit cutter.<br /> 0:03:11 I’ve shaped it with a wide angle on the tip, to give a broad shallow cut that I hope will generate interesting reflections from the light. The cutter was positioned over the work, and a series of fine cuts were made to create the pattern.<br /> 0:04:32 The milling needs a little tidying up at the edges, so I re-mounted the work in the lathe, and carefully skimmed the perimeter. I also pulled out the form tools that I usedin a previous video to make the pillars. I used them here to put a light camber on the outside edge, as well as a nice contour on the inside rim.<br /> 0:05:02 So before anything else I put on a coat of lacquer. I will need to redo this again later. But for now it’ll keep the oxidation to a minimum. So now on to the inner bezel. And in some respects this part was more difficult to make, simply because it ends up so small and flimsy.<br /> 0:05:24 I held it in a similar way using a super glue arbor, and started by truing up the disc, and then machining the recess for the chapter ring.<br /> 0:06:00 I turned up another arbor with a register that matched the rim, and then after it was fixed into place, I formed the basic profile of the bezel. I finished the final profiling by hand using this high speed steel graver.<br /> 0:06:29 And I know I’ve said it before, but I just can’t get enough of this freehand turning, especially on brass. So with both the inner and outer bezel complete, its time for a closer look at how it all fits together.<br /> 0:07:46 And that’s the bezel done for now. Now whilst the outer bezel is a good fit, I think it would be better to have a more robust idea to lock it in place, so in the next video, I’ll make some bezel screws that should do the job.</p> <p>References:</p> <p>John Wilding “Large Wheel Skeleton Clock” construction book can be purchased online from Ian T Cobb: </p> <p>https://www.clockmaking-brass.co.uk/clock_construction_books.htmL</p> <p>How To Make A Clock In The Home Machine Shop, Part 10, by Clickspring.</p> </div> </amp-selector> <div class="carousel-parent related-product"> <h2 class="related-title">Related Products</h2> <amp-carousel class="carousel-component" height="320px" layout="fixed-height" type="carousel"> <div class="product-item"> <div class="item-img"> <a href="https://m.ds-metalworks.com/wholesale-100-original-astm-a193-b7-combination-studs-step-down-studs-export-to-bahrain.html"> <amp-img src="https://www.ds-metalworks.com/uploads/astm-a193-b7-combo-studs-2.jpg" layout="fill" alt="Wholesale 100% Original ASTM A193 B7 Combination Studs Step Down Studs Export to Bahrain"></amp-img> </a> </div> <a href="https://m.ds-metalworks.com/wholesale-100-original-astm-a193-b7-combination-studs-step-down-studs-export-to-bahrain.html" class="item-title">Wholesale 100% Original ASTM A193 B7...</a> </div> <div class="product-item"> <div class="item-img"> <a href="https://m.ds-metalworks.com/cheapest-factory-bs4395-high-strength-friction-grip-bolts-with-nuts-and-washers-to-sweden-manufacturers.html"> <amp-img src="https://www.ds-metalworks.com/uploads/s-l1600.jpg" layout="fill" alt="Cheapest Factory BS4395 High strength friction grip bolts with Nuts and Washers to Sweden Manufacturers"></amp-img> </a> </div> <a href="https://m.ds-metalworks.com/cheapest-factory-bs4395-high-strength-friction-grip-bolts-with-nuts-and-washers-to-sweden-manufacturers.html" class="item-title">Cheapest Factory BS4395 High strengt...</a> </div> <div class="product-item"> <div class="item-img"> <a href="https://m.ds-metalworks.com/china-new-product-astm-a193-b7-tap-end-studs-double-end-studs-to-ethiopia-factory.html"> <amp-img src="https://www.ds-metalworks.com/uploads/b7-tap-end-stud-with-nut.jpg" layout="fill" alt="China New Product ASTM A193 B7 Tap End Studs Double End Studs to Ethiopia Factory"></amp-img> </a> </div> <a href="https://m.ds-metalworks.com/china-new-product-astm-a193-b7-tap-end-studs-double-end-studs-to-ethiopia-factory.html" class="item-title">China New Product ASTM A193 B7 Tap ...</a> </div> <div class="product-item"> <div class="item-img"> <a href="https://m.ds-metalworks.com/best-quality-and-factory-astm-a320-l7-all-threaded-rods-threaded-bars-to-turin-factories.html"> <amp-img src="https://www.ds-metalworks.com/uploads/astm-a320-l7-all-threaded-rods.jpg" layout="fill" alt="Best quality and factory ASTM A320 L7 All Threaded Rods Threaded Bars to Turin Factories"></amp-img> </a> </div> <a href="https://m.ds-metalworks.com/best-quality-and-factory-astm-a320-l7-all-threaded-rods-threaded-bars-to-turin-factories.html" class="item-title">Best quality and factory ASTM A320 L...</a> </div> <div class="product-item"> <div class="item-img"> <a href="https://m.ds-metalworks.com/new-delivery-for-din125a-flat-washers-wholesale-to-kyrgyzstan.html"> <amp-img src="https://www.ds-metalworks.com/uploads/din125a-flat-washers.jpg" layout="fill" alt="New Delivery for DIN125A Flat Washers Wholesale to Kyrgyzstan"></amp-img> </a> </div> <a href="https://m.ds-metalworks.com/new-delivery-for-din125a-flat-washers-wholesale-to-kyrgyzstan.html" class="item-title">New Delivery for DIN125A Flat Washer...</a> </div> <div class="product-item"> <div class="item-img"> <a href="https://m.ds-metalworks.com/manufacturer-of-astm-a320-l7-all-threaded-stud-bolts-for-macedonia-factories.html"> <amp-img src="https://www.ds-metalworks.com/uploads/astm-a320-l7-fully-threaded-stud-bolts.jpg" layout="fill" alt="Manufacturer of ASTM A320 L7 All Threaded Stud Bolts for Macedonia Factories"></amp-img> </a> </div> <a href="https://m.ds-metalworks.com/manufacturer-of-astm-a320-l7-all-threaded-stud-bolts-for-macedonia-factories.html" class="item-title">Manufacturer of ASTM A320 L7 All Th...</a> </div> </amp-carousel> </div> </div> </section> <footer class="page_footer"> <div class="footer-item footer-contact"> <h3 class="title">Contact Us</h3> <ul> <li class="foot-phone">Phone: <a href="Tel:+86-574-86521558">+86-574-86521558</a></li> <li class="foot-email">E-mail: <a href="mailto:sales@ds-metalworks.com">sales@ds-metalworks.com</a></li> <li class="foot-whatsapp"><a href="/featured/">Featured Products</a></li> </ul> </div> </footer> </body> </html>
