FoxMike Posted October 28, 2019 Report Posted October 28, 2019 Here is a picture of a Power Tow II which will handle the job. Quote

Or do you envision the it will go to the stop (ie. tubes will touch), but will not bend anything. Â Â Â Â Quote
Planegary Posted October 28, 2019 Author Report Posted October 28, 2019 the stops are set to not let it touch the tubes but i am hoping that the wheel wont want to turn and the turntable will do all the work. Will have to see how it works when iget home next week and after i make the ramp to aid in pulling it up on the turntable 2 Quote
carusoam Posted October 29, 2019 Report Posted October 29, 2019 The demo video is going to be awesome!  I have a 90° turn to get into my hangar. I haven’t yet figured out how to do it in one move... I thought following the same route as it came out would be good... Best regards, -a- 1 Quote

Call my turn 75º. then again, I'm pushing several hundred fewer pounds than you are.  My C is easier to push around than the lighter C172s I trained in. 1 Quote
Htwjr Posted October 30, 2019 Report Posted October 30, 2019 What's a towbar? Â The hanger that I lucked into has remote control fold up doors on both sides so you can taxi in and out. Â 1 Quote

Just don't leave any papers, towels or rags laying around, and no open books, either--stand 'em up! Quote
carusoam Posted October 31, 2019 Report Posted October 31, 2019 Best to drag the plane in and out until more is known about the support structure of the heavy doors... Stay on the centerline... good taxi skills might be required! Is that a rental? Â pics and costs are required... -a- Quote
Planegary Posted November 8, 2019 Author Report Posted November 8, 2019 Well building the tow bar saga continues. After getting the tow bar built it was time for the test. Attempting to Rachet the nose wheel onto the turntable made the ramp and the tow bar want to buck up. I made a longer more gradual ramp but it did the same thing.when I did this the ramp got between the rotating assemblies and ruined the bearing $16. Have to figure out to keep the ramp and tow bar from buching up. Maybe something that temporarily attaches to the turntable. Once I get this figured out I will replace the bearing and report on how it works. Quote
carusoam Posted November 8, 2019 Report Posted November 8, 2019 A similar bucking occurs with lawn tractor towing... all the weight is over the back wheels.... the front wants to come off the ground... It may not take a lot of weight to keep things down... I had an extra 6v battery lying around... the torque/arm might be helpful... PP thoughts only, not a mechanic... abest regards, -a- Quote

This got me to thinking about a towbar that attaches to a turntable for the fromt wheel to sit on. This would prevent oversteering the nosewheel. Is there anything on the market like that or has somebody already designed something like that? would hate to try to engineer something like that to only find that it doesnt work or somebody has already designed something.I would appreciate any input on this That’s what most of the FBOs have nowadays. The tugs have a little ramp they pull the nose onto so the nose never turns. Some of the citations have strict limitations too. Quote
MIm20c Posted November 8, 2019 Report Posted November 8, 2019 I think your idea is a great one. However, I think you will need 4 wheels total with two in front and two (caster type) behind the nose wheel. Have the ramp start just inside the casters to prevent it from bucking up. 1 Quote
RLCarter Posted November 9, 2019 Report Posted November 9, 2019 @Planegary can you get the turntable lower/same plane as the ramp? Also what bearing are you using, and from where? Quote
Planegary Posted November 9, 2019 Author Report Posted November 9, 2019 turntable is the same plane as the ramp already. when you start to pull the plane onto the ramp it tries to lift the turntable much like a hinge point . the bearing was a 1000lb bearing from ebay for a lazy susan 1 Quote
Planegary Posted November 9, 2019 Author Report Posted November 9, 2019 (edited) am thinking of putting a slideout onto the front of the ramp to make it (temporarily at least) a single unit to keep it from bucking to clarify the slideout would mount the ramp to the bottom of the turntable axle and be removed after the wheel is on the turntable Edited November 9, 2019 by Planegary clarification Quote

TWinter Posted November 10, 2019 Report Posted November 10, 2019 Supertow ll that was shown has the "LazySusan" concept that allows the tug to swivel. I've got one for sale $1700. She's a big beast. Quote
Planegary Posted November 10, 2019 Author Report Posted November 10, 2019 Part of my problem is I have to go off-roading to get the plane to the ramp. The taxiway does not connect to the ramp. That is why I am using a lawn tractor to tug and I am having to be extremely careful. I have to disconnect and hand turn 1 corner as it is Quote

Great equipment, works well, nose wheel never turns so no worries about turn radius, limits, crunching rods, regardless of how tightly the plane needs to maneuver. 1 Quote
RLCarter Posted November 10, 2019 Report Posted November 10, 2019 Not sure how it would work but could you use a coil spring in the handle something like this? The spring would just bend is turned too tight 1 Quote
