Extensions for Nova Cole Jaws

hi there when I did my last video of the diet and turned a platter I used my Cole jaws with these extensions that I made for them Harold asked me if I would do a video showing how I did these extensions so that's what I'm going to work on today before I do I have a amusing story to tell you it is I think it wasn't using a few days ago I was talking with my friend Gayle on the telephone she's married to my friend Phil and she said to me Gordon I hear your voice in my bedroom more often when I do my husband I said what and she said yeah when Phil goes to bed he likes to take his laptop and watch your videos so I just want to say Phil if you're watching this good night Gail the more I'm going to hear about that anyway today we'll be doing these extensions stick around one little tip I'd like to offer Cole jaws out this I believe it's aluminum plate and while they're very smooth I've actually had occasion to put a bowl on there and have it scratched by that so I've taken duct tape and put it across the plates and it's helped quite a lot now it's not normal duct tape I've had duct tape from the big-box stores that are just propped very stick to themselves I get this from Lee Valley it's really good and it sticks if you stick it to itself the glue faces together you're not going to get it apart and it's very difficult to take off small set of things so that's just a tip it helps a lot reducing the scratches on the face of the bowls I've already made a number of these extensions for the Cole jaws but I've never gone to the trouble of trying to make one as large as I can so I might as well do that now and have another one for later I put a straightedge it's fairly thin across the bed ways so I can measure from the top of that to the bottom of the Cole now that looks to be 2 and 1/2 inch almost exactly so if I take that two and a half inch and have that much space beneath they should be already so that's the size I'm going to chew for today I want the extension to be 2 and 1/2 inches below the bottom of this plate so the first thing I'll do is draw a line two and a half inches from the bottom across here now I'll find the center of that line 11 and 16 inch wide so 5 and 17 30 seconds doesn't have to be exact but I like to be as close as possible now the top of this is right here 7 and 3/16 from the bottom again five and seventeen thirty seconds it's from the point there that I'll be drawing an arc on the ark to be as close as possible to the bottom now I put this on here try to be sure that I'm somewhat equal put my two straight edges across here and all I really care about is that I'm inside the edge of the plywood so that will work just fine now what I have to do is take it to the band so I cut up there I'll true it up on the lathe while I'm here I will mark the spots for the screws that are going to hold this on I've used the seventh one from the bottom on the other so I'll just stay with that now when I drill holes I want to drill a larger hole first to accommodate the cap of the cap screw and that's going to be at 19:30 seconds of an inch then below that I'll put a through hole 15 sixty fourths of an inch huh put these marks on here so I know where to cut it so the first thing I'll do is cut out this pie shape I'm going to do one thing with these extensions that I have not done with the other ones this one's a little longer sticking out a little further so I'm going to use this hole here for a little additional support and I'm going to cut the wood off right here because I do not want to use this one I'm cutting the four pieces of plywood to size with the miter gauge set to 45 degrees now I will cut the wedges now I'm using the bandsaw to cut the arc I'll stay slightly outside the line and then clean it up on the disc sander I'm drilling the recesses to hide the heads of the cap screws and now the through holds with a fifteen sixty fourths inch bit all right now with the first one on here I can use this one as a template to mark out the next three for the hole to get everything perfectly done and I'll be my next step all for our fitting on here nicely now they're not perfect you can see there's a little bit higher here that is on the next one all the way around so I've drawn a pencil line and I'm just going to trim it down to that it definitely comes closer to the dance then the others hit now I just have to make another piece on here to hold whatever platters or bowls I want to put in this what I want to do on each of these now is put a strip on like I've done on the old one about an inch wide to do that I'm going to scribe a line around the outside I'll take this cut it out on the bandsaw then I'll scribe a line about one inch wide all the way around I'll glue that on the front of this then later after the glue dries I'll use my spindle sander to true it up with this one and once it's put on the lathe then I will turn the inside like this now I'm going to scry the line one inch from the outside of that curve I will cut this out on this side of the line it doesn't have to be terribly accurate and just mark this or I know where to cut it off I'll cut this off on the bandsaw now once the glue dries I'll take this and true this edge up with this one then when all four are finished I'll true up the inside on the lathe I have all four of these pieces cut out now and it's just a matter of gluing them to the wedges and I will let them dry for an hour or so and take them to the disk sander to clean up the outside edge I have to make sure that the outside edge slightly overhangs the bottom wedge piece so that I can true it up on the disc sander that one's ready to set aside and I can start on the next three with the glue set I'm now ready to sand this off on the disc sander I've attached a small piece of two-sided tape and I'm going to use that to hold a piece of plywood on there so that it's the same level and I can turn this over this way have it ready to be sanded and I can see when I'm getting close to the wedge and with that the outside is chewed up nicely I'll take this off put it on the next one when all four are finished I'll put them on the lathe and then I will true up and hollow the inside of this on the lathe the four wedges are mounted on the Cole jaws now and I'm ready to turn the inside before I do a word about safety I'm going to be turning this at twelve hundred and fifty rpm the Cole jaws are only rated for 600 so please if you don't think it's safe don't do it because I'm doing it I don't want you to have an accident sometime down the road and say well Gord did it so it must have been safe I do it because I've got confidence and I've done it before have no problem but I have to also admit anything can happen I could have a problem today you might see an accident take place so please one more time if you don't think it's safe don't do it i watch what Turner's and woodworkers on YouTube all the time doing things that make me shudder I wouldn't even think of doing them so one last time if you don't think it's safe don't do it now I want to clean up this make that halt with a little bit and then we'll take a look at the finished product and that brings us to the end of making its ditch and jaws for Cole jaws here I've asked for it so I hope you enjoyed this and I hope you enjoyed it too it's not that difficult anyone with a little bit of woodworking and woodturning knowledge should be able to put one of these together you may notice I've written down it's approximately 12 and 3/4 inches that's the minimum that I can squeeze down inside the hollow area the 13 and 7/8 is the maximum I can open this up and still get something in past the corners here so thank you for watching don't forget to subscribe hope you enjoyed this be safe in your shop thanks for watching
