Way to go, Chuck! I really like this part: "..but it works, and I built it!". What a neat thing, huh? I don't know about your resistor question. What kind of browser are you using to put up your posts? I have Firefox, and it works like you'd expect. When I hit the preview, the new post pops in above the box you type in. Hope you get it figured out. I wish I knew how to get a Photobucket video to show up in the post the way you've done it. Every time I try that, it puts what looks like a video frame in the post, but when you click on it, it opens a new window in Photobucket. That bugs me! Thanks for the update. You sound happy! Dean |

Hi Dean, a couple things, to get your postings down, go to my build log, the nine cylinder radial, in the beginning, as I had the same problems, and was aided very well by Cedge, who explained and demonstrated how to get pictures from photobucket posted with minimum problems, and real clarity. With regard to tooth count, I would strongly echo all the advice, and stay away from that eighty tooth gear. I'm satisfied with my table with seventy two, but would have prefered 90, looking back. If you'd like, I can run a log on how to index a plate, and use it to cut a ninety tooth gear, or for that matter, a seventy two tooth. When I had to make a couple of dials for a couple machines, I ran across a two hundred tooth plywood blade for a Skillsaw, and bought it for about three bucks, and made a simple indexing arrangement in my lathe spindle to index the dials with a hundred lines of three different lengths, if you found such a blade at Wally world or the like, that was a multiple of either 72 or 90, putting a blank on a spindle between centers on your mill, and cutting the teeth with a flycutter ground to fit the eighty tooth gear you have with some calculated "slop" to compensate for the slight difference in tooth count, you'd be in like Flynn. If you can't, like I said, I'd be glad to lay out the means, and put it up in a log. You are not going to want to redo this later, and if you use the eighty tooth gear, you will curse it often as you look back and still conclude you don't want to redo it, none the less, you will be happier with what you have, and doing it, than doing without because you don't have exactly what you want. I almost made a rotary table with a 39 tooth worm wheel, but resisted for years because it would only be good with special calculations each and every time it got used. Again, read through the beginning of my engine log and you'll find good clear instructions on putting up pictures and posting that work for this non-computer mechanic. :headbang: :lol: mad jack |

Last night I turned a pair of bearing holders for the worm axil. Today I made a clamp set from 1 1/2" steel angle. and milled slots in the body of the RT to clamp it flat and vertical. I'll post pictures later. Dean, I added the video to my post from Photobucket, just like adding a regular picture. I save the video from my camera to the album, I Clicked on the img code box and copied the code and pasted it into the post. I don't know what it is about clicking preview, sometimes it works fine and my preview window apears above the post composition window, sometimes the post reply page just disapears.. Seems to disapear if I compose a long post directly without using word to compose and copy/past to the post window... mad jack, I did go with the 60 tooth gear. Next, I think I will start over on the top plate, if I can figure out how to locate the bearing so the axil and thus the gear are positioned correctly to the worm. So far, I have learned lots, broken a drill bit, a tap, and a 1/8 end mill. Material costs total $24, broken tools about $15, and I have a basic RT! I'm really enjoying this! Chuck in E. TN |

It was the Photobucket Videos that didn't do right. They put a frame in the post just like Chuck had in his earlier post with his R/T Movie, but when you click on them, it goes to Pbucket to show it. It just bugged me! Anyway, I think Chuck has me straightened out on that. Thanks, you two! Glad you settled on the 60t gear. It will make things worlds better for you than that 80t beast! It makes it more like using a lathe dial when the numbers all come out even. Less chance to make a bad mistake trying to count half turns and all that nonsense. I type up all my long posts for my project threads in Notepad, too. Just in case... Keep on having fun! Dean |

Well Chuck, its good to hear you decided on the sixty tooth, I think it will make you happy in the long run, those little glitches like broken drills and taps don't matter much when the project works and meets the challenge you put before yourself, with success. You'll probably spend more time making tooling and accessories for it, than you spent making the table its self, before you're done I wager. I wish I had v-belts to worry about slipping, my flat belts slip all the time, and I'm looking at putting in a transmission from a lawn tractor so I can shift gears instead of deciding what pulley I want my flat belt to "slip on for this turning". As far as the resistor goes, if it is about three eights long in the body, with coaxial leads and a color code, it is a quarter watt resistor. If it looks the same only twice the size, as in a little longer in the body than half an inch, and with coaxial leads and color code on it, it's a half watt resistor. If it's a power resistor with real current requirements/limitations, it will be a rectangular block of ceramic with a wire wound resistor inside, and ceramic goop fired across covering the wire, and its resistance and power rating would be printed on the "top" of the ceramic block. If you have problems finding the right one, e-mail me, and I probably have one I can send you, being as you're in Tennessee, and just a few hours away. By the way, if it is a quarter watt resistor, and it burned out, replacing it with a half watt would be a good idea. I spent about thirty odd years in electronics so I probably have the parts you need, or at least know of easy access. let me know, I'd be happy to help. good job on the table, and good to see you have it under your belt, so to speak :mmr: I like this club :headbang: mad jack |
