Q & A
What was the first step in modifying the steel to resemble a toe bar?
-The first step involved bending the 1-in steel into a shape that resembled a toe bar.
Why did the narrator have to disassemble the chassis again?
-The narrator had to disassemble the chassis again to fix the toe bar onto the bottom beam of the front turning axle.
How did the narrator lift the top beam and rails without fully disassembling the chassis?
-The narrator used a block and tackle to lift the top beam and all the rails up and out of the way.
What was the issue with the hole that the narrator initially made?
-The issue with the initial hole was that it was not big enough to get a socket onto the nut, leaving it only fingertight.
What did the narrator's dad help with in the process?
-The narrator's dad helped by finding an old handle with a perfect diameter of 27 mm, which was used to drill the center point of the drill bit.
What were the three requirements for the system to attach the toe bar to the beam?
-The three requirements were that the system had to be strong enough to pull hundreds of kilograms up a gentle hill, detachable to prevent theft, and aesthetically pleasing.
Why did the narrator decide against using off-the-shelf options for attaching the toe bar?
-The narrator decided against using off-the-shelf options because they either looked unsatisfactory or relied on thin screws or bolts that were not reliable for long-term use with oak.
What was the challenge in finding the right bolt for the toe bar attachment?
-The challenge was finding a long enough galvanized bolt with a 1-in eye, as they were almost impossible to find, and the only place that had them did not ship to France.
How did the narrator ensure the toe bar attachment was secure?
-The narrator used a large, chunky bolt that went all the way through the beam with a washer and nut on the back side, rotated 90 degrees, and also added beta clips onto the feet of the toe bar to prevent slipping.
What was the issue with the toe bar binding to the eye during the initial testing?
-The toe bar created an outward force that caused it to bind with the eye in a way that wouldn't release until the narrator applied some mechanical advantage from the straps.
How did the narrator test the completed toe bar and what was the outcome?
-The narrator drove the structure around a field to see if anything broke, and thankfully, nothing did, indicating the toe bar was successful.
Outlines
🔧 Challenging Assembly and Design Adjustments
The first paragraph describes the intricate process of bending steel into a toe bar and the challenges faced in attaching it to the bottom beam of the front turning axle. The task required disassembling the chassis again, but this time using a block and tackle to lift the top beam and rails out of the way. The narrator also discusses the difficulty of enlarging a hole due to its insufficient size and the improvisation required to use a 27 mm handle for drilling. The paragraph highlights the importance of creating a strong, detachable, and aesthetically pleasing system for attaching the toe bar to the beam. The challenges of finding the right materials and the issues with store-bought options are also discussed, emphasizing the need for a reliable and sturdy attachment method.
🛠️ Refinement and Testing of the Toe Bar System
In the second paragraph, the focus shifts to the refinement of the toe bar system and the testing of its functionality. The narrator describes the process of cutting the toe bar feet to uniform lengths and drilling additional holes for beta clips to prevent the toe bar from slipping. The challenges of dealing with the outward force and the binding of the toe bar are also mentioned, along with the use of straps for mechanical advantage. The paragraph concludes with the successful fitting of the toe bar and the anticipation of its performance, as well as the narrator's intention to add more washers and clips for further stability.
🚜 Field Testing and Future Plans
The third paragraph details the field testing of the toe bar system and the narrator's satisfaction with its performance. Despite the initial challenges, the toe bar was successful in turning the bottom axle with minimal effort. The narrator also expresses the desire to create a nice tie detail below the tow hitch, acknowledging that their blacksmithing skills are still developing. The paragraph ends with the narrator's plans for the future, including bending thin strips of oak for curved roof beams and the anticipation of the next video where they will be working on different materials.
