One of the most important angles in front end geometry is Ackerman. With your spindles at 90 degrees off of your tie rod points, your inner front wheel will not compensate for the smaller radius it travels as it goes around the turn. This gives a scrub effect on your inside wheel. If you point the tie rod mounts at the center of your rear axle, you will have close to neutral. A bit more, and your inside wheel will help pull you into the turns. Oh, and a slightly bigger diameter rear outside tire will help also. Just been racing dirt for the last 40 years. Be well, and have fun
Great video!!! Love what you are doing. This can be so much help to a lot of people. Keep up the great work and explanations. Looking forward to the next video. Have a great weekend!!!
I would live an engineering breakdown of those internally mounted disc brake front spindles that were shown in a previous video! Those are impressive, great vid!
You know your stuff….I am building one off of your videos. I’m debating on keeping the four speed transmission for the back or making it a live axle. I have some springs the act as suspension on the front, I’m hoping that helps. I just need to figure out the rear.
Ackerman can be achieved with the center pitman arm... forward facing spindles are silly but if you must it's still totally doable and very simple with center steering(drag link steering is another story).. also Ackerman absolutely helps in counter steer especially with asymmetrical alignment for American leftist tendencies...
That was pretty in depth. You explained it just fine. I look forward to seeing the final setup. Could you potentially switch it to a front steer axle? Are you allowed to use a rack? Good stuff man, I like it.
There isn't anything in the rules against a rack and pinion steering setup, I've thought about it before but it would be tricky to setup the steering shaft to it. This will actually be a front steer axle btw, I like it in front to allow more room for the motor pulley and it's easier to work on. Next video will show the mower on all 4 tires finally lol
Great explanation about front ends but I still don't understand why you didn't go with the Ackerman effect? I'm in the process of building my first mower and thought it needs Ackerman in the front.
Thanks for watching and commenting. Theres two reasons why I didn't include any ackerman, first off is because I'm using a center steering pivot point instead of a pitman arm off of a spindle going back to the steering shaft. I feel that the pivot point in front of the axle gives much more accessibility for maintenance, assemble and repairs as well as more clearance for the pully and belt behind the axle. The other reason is often in dirt racing front ends are set up with a "parallel" ratio for both front spindles with no ackerman due to how often you are counter steering in the turns. After all ackerman would be entirely opposite when you have the wheels turned to the right while going around a left hand turn.
Hi, great job you work so well. Maybe you already said but after viewing 3 times each video I can't find what's the size of the front tire and the front wheel.
How are you liking the step through chassis? I like driving them because leg placement feels more natural to me, but they get cramped under the fenders without the box.
So far so good, it looks like it might be tight to fit in the chain tensioner since the axle is so close to the transmission but I think it'll work out. I'm looking forward to the first sit test after I lower the seat into the fender lol
Besides the mower have a question on the ohv briggs engines and if a set of 2 chevy 350 roller rockers will work in one of the ohv engines. If I'm not mistaken I know for the kart guys with the horizontal briggs animal ohv engines they will work in those small block heads. Know of a couple of guys that's used them in those engines.
I don’t have social media, but I’m trying to work on my front axles. I was wondering if there is a way I can ask you some questions about the more technical side of your front axle and spindles?
My profession is a plumber, all the mechanical and metal work is just a hobby for me. The tools are pretty easily found in the old rust belt area, after all the Bridgeport's were made in the same state I live in.
TheJanticJournal thx. You have my son fixated on making one of these conversions. We’re tackling an old John Deere 110. I don’t have those machines but we have welders and drill press. So trying to make a go of it.
Good to hear! When I made my first two mowers that's about all I had too. I find an angle grinder is very useful and versatile tool for people without a lot of other equipment.
Loving the detail, mate. Thanks for a very cool series 👍🏻🫶

Thanks for the input!
I can watch your videos all day,I'm learning so much, thanks.
i am actually using this to build a racing lawnmower
Great video sir. You do nice work. Thumbs up 👍
Thank you so much for making this build serie
This is a long shot, but do you have the drawings for the front axle design?
Great video!!! Love what you are doing. This can be so much help to a lot of people. Keep up the great work and explanations. Looking forward to the next video. Have a great weekend!!!
Very methodical !
You have one of the few sets of videos that I can watch repetitively, great videos .
Great video really helping me on what I’m going to do with my mower

Thanks, I just kinda winged it on that front end. It all worked out but wasn't as planned out with jigs like the current build.
A lot of great work! It’s looking awesome!

Good video. On the axle tube , 2x1.5" ? what are the cut degrees you put on it.. the end cuts dont look square. longer video would be okay..
The end of the tube are cut at 10 degrees to match the king pin inclination angle of the spindles. Thanks for the view and comment!
Nice videos I’ve watched them all like 3 times but could you tell me what you used for your front spindles and wheels

I know its an old video, but what angle do you have the plate that holds the heim joints to the axle?

Do you sell them spindles do ya ??
Sorry, not interested in selling parts.
Do you have a link to the knock off carlise tires
What rectangular tube wall thickness did you go with on your axle?
.125"
So what’s your background? Not many people with a mill and lathe in their shop? And how’d you get those tools?

this is NOT a mower longer..!!!!
