Popular Post difalkner Posted February 15, 2018 Popular Post Report Share Posted February 15, 2018 I have never posted into this Woodturning and Lathes area, so I guess this is a first. A friend asked me to cut him a 16" Longworth chuck so today I tested my drawing that I did in Fusion 360 by cutting a 12" chuck. Looks like it came out just fine so I thought I would offer them in our Etsy shop. You can click on the link in my signature and see the offering but I didn't want to post a link like I was pushing it, just thought you lathe guys might want to see this - I used to turn a fair amount and still have my Oliver 8' bed lathe but it's not being used 'cause it's 3 phase and I don't have time to do any turning anyway. So if y'all see something in the Etsy listing that doesn't look right or that I have worded incorrectly I would appreciate a heads up. Thanks!

Marmotjr Posted February 15, 2018 Report Share Posted February 15, 2018 Throw a 10" version up there too, and I might be buying one. It's been on my to build list for some time, and If I could shortcut the routing process...... 2 Quote Link to comment Share on other sites More sharing options...
difalkner Posted February 15, 2018 Author Report Share Posted February 15, 2018 Can do! What do you think about the design? I know some people like the symmetrical slot design and some like this design with the short slot. I can do them either way... Another thought - should a 10" have just 6 slots instead of 8? Eight slots seems like a lot of slots for a smaller disc. David Quote Link to comment Share on other sites More sharing options...
legenddc Posted February 15, 2018 Report Share Posted February 15, 2018 Very cool. I'm not in the market for one yet, but will remember it when I am. You might also be able to sell plain discs to make sanding discs for lathes. 1 Quote Link to comment Share on other sites More sharing options...
Jfitz Posted February 15, 2018 Report Share Posted February 15, 2018 I also am not currently in the market - but some day I will be. From what I know about how these operate - which is only minimal - how critical is it that it be mounted precisely center on the faceplate? Will a little deviation cause a problem in securing the item and getting a round shape? 1 Quote Link to comment Share on other sites More sharing options...

Will a little deviation cause a problem in securing the item and getting a round shape? I wouldn't think it would be critical to the thousandth or even hundredth. But one reason I put a tight tolerance hole in the center is to aid in lining it up perfectly. If the outside perimeter is off a tiny bit and it bothers someone they can always turn it to be concentric. The grippers I have seen are soft enough that there is probably a bit of tolerance in them when fastening your bowl or lid or whatever you mount in the Longworth chuck. But I speak from a point of woodworking knowledge and no experience with using one of these chucks. One thing I can do is locate the holes for mounting the face plate if I have accurate dimensions of the face plate being used. That's what I will be doing for my friend on Saturday when we cut his 16" chuck. I'll use the CNC to place a 1/16" dia. mark 1/16" deep and then he can drill the appropriate pilot hole size for his screws. I'm sort of like JW Gallagher when he started building guitars. He didn't play guitar but Doc Watson thought enough of them to use Gallagher guitars for years. David Quote Link to comment Share on other sites More sharing options...

David I imagine it would be the same size. You might want to look at what size they sell sanding discs for stationary sanders for. Quote Link to comment Share on other sites More sharing options...
difalkner Posted February 16, 2018 Author Report Share Posted February 16, 2018 Here's the 10" size with all long slots (10" only has 6 slots because 8 would be too crowded and possibly weaken the disc). After playing with these a bit I like the one with all long slots better. David 1 Quote Link to comment Share on other sites More sharing options...
thatCharlieDude Posted February 16, 2018 Report Share Posted February 16, 2018 Very cool! I can't wait to order one (but I have to wait until pay day). How is your friend planning on attaching it? Is he attaching it to a piece of plywood and then to a faceplate or chuck or directly to a chuck? Also, what's he using for the pins, is he making his own or store bought ones? Thanks!

difalkner Posted February 16, 2018 Author Report Share Posted February 16, 2018 He has a face plate that will be dedicated to this chuck. He mentioned some commercially available grippers but also said he might stop by Lowe's or HD and pick up some chair leg feet and give that a try first. This is the face plate he'll use and since he gave me good dimensions I will use the CNC to put a 1/16" depression where the screws will go. So hopefully when he drills his pilot holes the plates will be concentric with his spindle. If not he can true up the outer perimeter a bit on the lathe.

I just looked at some of the commercial kits and they look just like the bottle stoppers, bolts and wingnuts you can get from the hardware store and they weren't cheap. Looks like you can make the grippers pretty easily yourself and much cheaper. I like his faceplate. 1 Quote Link to comment Share on other sites More sharing options...
