BX25 Full Cage Rollbar

[Artisan]

Got It! yesterday while at the tractor supply I went on a hunt in
their expansive boneyard. I found piles of ROPS systems but nothing
I felt I could use and try to make it storebought at the same time.
I believe I have pretty much decided to go w/ 1-3/4" tube.

 

[swick1]

Woo! Git r dun!

 

[Artisan]

OK I started drawing! This is VERY close to being sent to cut...
These are the lower A pillar supports only, port and starboard. :thumbsup:
I have checked and rechecked and I am quite confident in my design
to date, as a matter of fact, I am betting my life on it.

I will not be able to explain, except, the white parts mount vertical
left and right of FEL stancion, red part mounts vertical and
to the rear of the FEL stancion. The yellow, cyan, and green parts
mount horizontal and at rear of stancion with green on the bottom,
cyan touching green just above it w/ plug welds+ and yellow farther up.

Tubing will be 1-3/4" tube, .120 wall .

Add a 1" monster Shoulder bolt in lieu of the OE FEL removable
mounting pin, perhaps add an X brace and perhaps a horizontal
(windshield bar) just above the instrument cluster and I will survive
a LOT, whereas w/o it, and just a the OE Rops I have little.

It should even work w/o the FEL on w/ 4 spacers. No problemo'!
Impact padding will stop the ocassional BONK of the cranial.

Everything interlocks...
If all goes as planned this is going to be VERY nice. I am
quite excited, I went thru one design, Alpha and trashed it
in favor of this, BETA. I need to wake up and chew on it, my mind
works best early AM, before the world tarnishes it....:confused2:

I might just sell them, not as roll cages, but maybe for off road racing
only perhaps, no warranty expressed or implied, racing is dangerous! :laughing:

I think it will be a secondary support / hand hold ONLY to OE Canopy. :thumbsup:
I might even sell it in parts so a guy can weld his own...we shall see.
Gotta roll the dice and get the parts cut and pray I didn't measure wrong.
Reminds me of the time that silly part would not fit, no matter how
much I cut off it, it was still too short!

Looks like a nice design, CAD is a pretty incredible program! I'm glad that you got your parts in, and I hope it turns out very well for you! Did you order from a CNC machining site?

Monrovia WaterJet

I email in nested, complete parts, snapped perfect and get back exactly what I drew.

 

[swick1]

Laser or plasma would be faster and cheaper. I avoid waterjet as much as possible because it is slow and makes your parts rust.

Rust is just a minor inconveince when you own a glass bead blaster.
Larger items get the pneumatic SpiralCool disc and other conditioning pads.

Water jetting, plasma. laser, all are a method to the same end.

The waterjetter I use is in my hometown, so no shipping, I usually
just email .dwg files and they write back and I go get and it is a done
deal.

BUTSOMEHOWEVER, I would love links to your plasma and laser folks if you please !!! :thumbsup:
If it is signifacantly cheaper w/ shipping I am a buyer! Thank You in Advance!

Wow????

1. Your response has nothing to do with this older post, or to what I was discussing about safety, and ROPS. If you don't like what I was advocating, instead of making very inaccurate claims about my tractor, or how safe my set up is, with no valid information, other than very rude assertions. If you are assuming that my knowledge comes from just owning this tractor, than you are wrong.

2. My tractor was actually rated for far more weight on the front than what I have, and came standard with more weight than this, but the weights are oversized because of their design. I am not sure that you know what you are looking at.

3. Iseki/Bolens tractors are designed for Cat 1 implements, and I have no issue using them. These are not by any means "riding lawn mowers" like you quoted. They are not a full size tractor, but they have a long history around the world in agricultural farming, and 200lbs of counter weight on a one ton tractor, is not by any means, over-rated.

4. ANY weights that are attached to the front of a tractor, in a roll over can come off, and strike an operator, however to suggest, that you should not use them in order to counter balance your center of gravity and risk a roll over is irresponsible on your part, and finally,

5. I am not sure why I even responded to you because having no educated discussions with you in the past, a post like this tells me that you are lurking, and looking to create issues. If you want to join a discussion, and make an educated point, then have your facts straight, and stick to the discussion. Please don't accuse me of risking others members life's, because of you baseless claims. All of the posts that I responded to in this thread were educated, and I respect the posters opinions in each one, however I question your intentions. Enough said.

LOL at you! You don't like it when someone points out the safety issued with your little tractor do you. What I posted had everything to do with this thread. "SAFETY" It's his tractor not yours. Think about it DA! If it is safe with the ROPS that is on it now, then anything he adds will just make it safer. You're just one of the people in this world that over thinks everything.AND THINK YOU KNOW IT ALL. Now STFU and let the man build this roll bars into this ROPS. Thanks for removing the picture of the cat 1 lawnmower with the over loaded cat3 weights dangerously hanging off the front of it. I would not want one of the educated city slicker to see that and think it was safe and get killed by it. I'm sure you would not want this also.

It is possible to introduce stress concentrations by adding more material, thereby making the original ROPS unsafe. However, as long as you're just clamping to it instead of drilling lots of big tapped holes into the bar, you should be fine. That doesn't mean a lawyer won't tear you a new one in the lawsuit when somebody dies under it. I think it's pretty unlikely though and not really worth worrying about too much. The probability of being injured from a falling branch or being strangled when you run into one without FOPS, however, is much higher.

Food for thought when designing:

I for one don't appreciate the vulgar and inanely stupid language. I hope the admin sees this and is willing to act.

DJames55, you got to ask yourself this. Would you tell that man to his face to stfu?
Really???, you sure about that, do you know the mans training? .....Ahh huh....

I was just gonna look the other way but but now you have stepped on a readers
toes and THAT I do not like. DJames55, you have the option to EDIT your post
for so much time, if it is PAST that time then YOU NEED to ask ADMIN's to
EDIT or Delete your post and I HIGHLY recommend it is accomponied w/ an apology.

NHMITCH I was going to suggest you ignore it...you din't, your call, let it go please.

DJames55 I will be VERY surprised if you are not involuntarily initiated into the band.
YOU ACT or others will I do believe...

This forum has rules...their strick...be forwarned.

If you navigate to post #82 in my BX25 Goodies thread you can see a hint
of things to come via a U-Tube video I just made.

You can see one of the lower cage brackets I picture'd quite small & recently
in this thread. It is printed 1:1 scale on paper. EVERYONE needs to learn
how to draw in CAD, is is so cool. Look at that piece of paper, that is
the part I drew, printed and put in place prior to pulling the water-jet trigger...
It makes conceptial become reality and can show a problem before
you spend the big money for parts to be cut.

Artisan,

Sorry for the issues on your thread. I blocked his future posts, so I don't see them. I apologize if it has taken away from what you are working towards here, and you're right, I shouldn't have responded. I am not sure that I understand people intentions like this. Anyway, thank you, and hopefully we can get back to your roll cage design...How did the cage that you had fabricated come out?

 

[swick1]

Artisan, I agree that cam is great but I am working on getting a plasma cutter and more hand tools so I can just build stuff instead of fooling around with the cnc manufacturing companies. Every tool has its place and I want it all.

 

[ThomasH]

That's an impressive setup. Thanks for the ideas ...

 

[Artisan]

So I pulled the trigger on a rear anchor design. It took days of pondering
and vasilating back and forth over this or that or that and this on and on.
I finally decided on the strongest, simplest design my cranial could conjure up.
One of my demands was the ability to remove the canopy w/o too much bs.
I will be able too by pulling 2 U-Bolts...done deal.
In this first pic I will pull the U-Bolts holding the Canopy to the ROPS
and I will marry in a piece of 3" x 3" x .250" wall square tube,
w/ radius'd-box-ends. I will prob go w/ 9/16" fine thread pro U-Bolts
(8) w/ tall nuts and thick washers which will marry the rear A Pillar
anchor to the OE ROPS w/o violating the OE ROPS one iota... :thumbsup:

All U-Bolts will be 3.125" ID x 6ish" long professionally made.

I started the process of making a template and plasma cutting the stock.
The radius of teh OE ROPS is not a consistant radius.

Laying in .5" x .250" thick short pieces of flat bar to make a radius'd end that is box'd.
It will be VERY strong. Stronger than the ROPS I am sure.

Viola! 1 end roughed in. The trick is going to be cutting teh other end.
I am kinda **** and I want a snug fit...oh the pains...oh the pains.

Can ya buy the OE frame paint from the dealer?
That grey color?

 

[swick1]

I like your setup. I think I'm going to do pins for my canopy. I'll probably have some 3/16" or 1/4" plate brackets bolted to each side of the rops and use pins to retain the fops at the top of the rops and bottom of the loader.

I'm going to try to make it light enough for me to remove on my own without tools. I think it will vibrate a little but I'm going to mount it with lots of rubber.

I think the roof will be 1/16" aluminum diamond plate with a 2" by 1/8" thick square steel tubing perimeter frame. I will put a rubber gasket between the aluminum and steel to dampen the vibrations.

I plan on attaching worklights to it and using automotive style electrical disconnects for easy removal.

I was at the dealer last week and they had a couple of different oranges (I had to ask which was the correct one) - and they also had at least 2 different greys.

Long answer short - yes, You should be able to get the correct grey color at the dealer.
