I'm at that stage right now, and several of the guys on this list pointed it out to me. A picture is in the instructions. --- On Sun, 1/10/10, sam hord wrote: > From: sam hord > Subject: Zenith701801-List: Re: Zenith701801-List Digest: 1 Msgs - 01/08/10 > To: zenith701801-list@matronics.com > Date: Sunday, January 10, 2010, 11:22 AM > How are you keeping the elevater cables > separated so they do not rub and wear? > Sam > > On Fri, Jan 8, 2010 at 11:58 PM, > Zenith701801-List Digest Server > wrote: > > * > > > > ======================== > > Online Versions of Today's List Digest Archive > > ======================== > > > > Today's complete Zenith701801-List Digest can also be > found in either of the > > two Web Links listed below.

I was wondering if I could replace the front fork tube with stainless steel parts and get a similar look. I would need to make sure that the replacement had the same strength as the original. So, with the help of my son, we did a SolidWorks analysis of a 4130N tube, 2 inch diameter, 21 inches long with a 0.065" wall. The top is solidly anchored and a force is applied horizontally at the bottom. Here is a link of the simulation video that SolidWorks made: http://www.youtube.com/watch?v=w8uamuysV_8 The video ends when the fork tube fails. It took a force of 540 lbs. As you can see, the tube bent a lot before it failed. If you make the fork tube stronger you are likely to move the loads elsewhere and it will break somewhere else. One thing comes to mind here, if you bend the front axle and lock up the wheel you are going to see a lot more than 540lbs. There was a picture on this list over a year ago that showed a bent fork tube after what was claimed to be a normal landing. I don't know how common this problem actually is. We substituted the fork tube with T-316L stainless steel in the simulation. It took a wall thickness of 0.250" before we arrived at a similar result. Since that would make the fork tube about four times as heavy, I have decided to stay with the 4130N of the plans. I may go up one notch in thickness of 4130N though. I might also replace the front axle with a solid shaft. On the shaft I have now, I machined bushings and welded them in place.
