Guest guest Posted October 16, 1999 Report Share Posted October 16, 1999 I just wanted to mention -- the key component to Gita-nagari's ox power unit (which is the picture you mentioned in the May/June 1991 issue of Back to Godhead) was the high-torque drive unit: "Five oxen pull the tongues, which are attached to the master gear, generating power with a circular motion. Then, the motion is geared up, and the direction of the rotation is changed so that we end up with a shaft spinning at 765 rpm that will provide 60 horse-power. By using various types of pulleys off the final shaft, any range of speed can be achieved to drive any type of equipment desired... "Instead of using chain-driven sprockets here, we used a serrated belt drive. the belt set-up was high mechanical effeciency, high resistance to wear, never needs lubrication and runs very quietly. It needs no extra sprocket to keep it tight, as long s the center distance between the shafts is accurte. We selected T.B. Wood's High Torque Drive unit (Fig. 18). To gear it up 3 1/2 times, we used a bottom sprocket, having 112 teeth, and a top supprt having 32 teeth. The belt is 55 mm wide and 2,100 mm long. This requires a center distance of 20.17 inches between shafts." *Gita-nagari's Ox Power Unit* by Paramananda dasa and Vaisnava dasa, 1989 This ox power unit was build over 10 years ago. It would be interesting how other devotees have improved on it. This is just the type of project that would be ideal to develop in a Varnasrama College -- so there could be several different models to compare. Students and teachers could learn from the different attempts. One reason why the HTD unit was important in this was to gear the wheel up fast enough to actually saw the wood. I believe that the oxen were pulling the tongues at about 2 rpm -- the motion was geared up to the extreme that the circular saw blade was spinning about 2000 rpm. your servant, Hare Krsna dasi On Sat, 16 Oct 1999, COM: Samba (das) SDG (Mauritius) wrote: > [Text 2705137 from COM] > > > A number of years ago thee was a very exciting picture in the BTG showing > > a group of ten oxen turning a wood saw.

Guest guest Posted December 7, 1999 Report Share Posted December 7, 1999 I don't get it. I have been d to com for a long time. I don't what you mean by directly. I usually just go to www.com.org/com and presto there I am. Now I get that the url is no longer there. I just don't get it. Is there something that has changed.

COM is not on the WWW, it is on Telnet which is a separate component of the internet from the Web (WWW =World Wide Web). Chaya, can you him directly to the Cow conference? Could someone give him info how to join COM directly? I only did it once and forgot how. There may be a $30 one time fee for joining COM. It does have expenses, and Harikesh is no longer footing the bill for everyone else's benefit, have to all contribute to keep it going. someone else was footing the bill for the mirror site, either they couldn't afford it any longer or hackers got him or something. Anyone actually know? Quote Link to comment Share on other sites More sharing options...
