Title: ARMA super mod!
Post by: jerb on September 19, 2010, 08:39:26 pm
well after trying to figure how to change a few things  on the super mod i was building i decided to start from scratch and learning from the mistakes i made on the first one, i believe this build is going to be way better and way stronger then old chassis, i started with a walk through mtd chassis, i uses 1 1/2'' square tubing for front axle and 1'' square tubing for chassis braces..

Post by: jerb on September 27, 2010, 12:13:53 am
I hope to have it all done by then with a mild engine, and if so i will be there! Hopefully George and few other super/mods be there or maybe race with the super sportsman's!

Post by: jerb on October 03, 2010, 06:54:38 pm
well got the steering done, with just a little under 1/2 turn lock to lock i love it, with a vertical engine and rear steer was not easy, moved engine back about 3 inches, raised engine about an inch as well to make exhaust easier to build, and the fact that walk through chassis does not have a very flat spot for engine to be mounted, figured this was easier to do, and gain some crankshaft to ground clearance as well, fuel tank will be mounted in front grill area, and have not yet decided if gonna run a battery or not, next up is getting ragb mounted, seat is higher now, maybe able to put ragb back far enough that chain will not run through the fender, just have to see.....more later!

Hey jerb, do u think u will get enough tire contact 4 good traction with that small a dia.? seems maybe a little small 2 me, but i guess that depends on the power u will b puttin to em:)

Oh i no you guys run kart tires in the front i was wondering about kart tires all the way around...... hubs are cheaper rims are cheaper and tires are farely cheap.

Well does anyone run a 6" in rear with sucsess? im goin w/ 8" on my twin build, but was wondering if the 6 would hold enough traction 4 a built single?
Title: Re: ARMA super mod!
Post by: Rusty Moosbrugger on October 08, 2010, 04:12:40 pm
I run 6" and get all the traction I need
Title: Re: ARMA super mod!

I run the 6" wheels on my mod-x but I do have automatic traction control :D
Title: Re: ARMA super mod!
Post by: mtd#7 on October 08, 2010, 07:24:15 pm
i run 6in rears and they hook up just fine, and if you look at alot of mini sportsmans they run 6in rears i dont see alot of them fighting for traction, but i do see alot of pictures with them pullin the front wheels off of a corner
Title: Re: ARMA super mod!
Post by: George Herrin on October 08, 2010, 08:09:21 pm
A mini is not a Super Modified. The 6 inch wheels will do well for mild twins even ok for more... BUt when it gets real serious I am not 100% convinced yet. I am running them on my Super Sportsman. And so far love em. And it will be different tracks willlike em better than others like anything else. Anything can be made to hook IF ya know how...

Traction 101:
1: Install tires on rims, any tire, doesn't matter.
2: Air up to approximately past flat.
3: Install one George (that's the secret ingredient)

well been doing some odds and ends here and there, finished the running boards, made some pedals out of 1/2'' steel, just used some heat and a vise to bend them,
(http://i272.photobucket.com/albums/jj163/jerb-2008/th_034.jpg) (http://s272.photobucket.com/albums/jj163/jerb-2008/?action=view&current=034.jpg)

for the base of the pedals i used 5/8'' pipe, drilled out center to 1/2'' and used 1/2''x3/8'' oil-lite bushings, then welded the pedals to the pipe and bolted them in place with 3/8'' bolts, turned out pretty good for about $12 in metal and bushings, this weekend gonna try and get ragb mounted and clutch done, hopefully be a roller in next couple weeks!

Title: Re: ARMA super mod!
Post by: jerb on October 15, 2010, 12:47:53 am
dont let money discourage you, as it sits i have roughly $200 in it, that not counting ragb and the parts i have waiting to be put on it, tell you now it will have a very mild intek for starter of 2011, billet flywheel, rods and some updated valvetrain, but that is it, some porting work, stock cam, and mower tires on rear for time being, i been keeping track of cost of what it takes to build, i work in a well equipped shop, which helps a bunch, but could be duplicated reasonable, heck i could help alot of fellow racers out on pieces for a great price....i enjoy building stuff! when its done i will have a cost breakdown of exactly what it cost and will show it can be done pretty reasonable...... ;)
Title: Re: ARMA super mod!
Post by: fordman21 on October 15, 2010, 09:15:32 am
I think that is the biggest misconception about this style of chassis. After talking with racers in Ohio and reading here and there, most believe its expensive to get into a chassis like this. It doesn't cost one dime more to build a supermod/outlaw machine then it does a supersportsman or BP, its all the same parts just installed a bit different.
They do look pretty wild and fast, but in reality all those changes that make them look that way are really done to improve safety.
Title: Re: ARMA super mod!
Post by: George Herrin on October 15, 2010, 02:38:40 pm
Yup cost is about the same.... The biggest Difference is the Build. We are so use to building one way that when it comes to building these we gotta get out of the box and think outside the box. NOW there are getting to be plenty of build pictures posted that it really helps the new folks building them the first time.
Title: Re: ARMA super mod!
Post by: jerb on October 16, 2010, 07:03:16 pm
got the ragb mounted today, used 1/4'' by 6'' flat iron then trimmed to fit for a mount, made the outside bearing un-boltable so i could quickly and easily change the front sprocket, i have 4 different front sprockets that cost about as much as 1 rear sprocket, saves a little money, once you figure out a good all around rear sprocket, gonna start with a 58 and 13 and go drom there!

Title: Re: ARMA super mod!

Not odd really its the most commonly used in Canada and several here states side.
Title: Re: ARMA super mod!
Post by: fordman21 on October 17, 2010, 02:03:05 pm
Looks good,  simple,  tough with a bearing on both sides,  easily accessible for gear changes,  ties in the rest of the chassis,  nice job!   I assume the box is mounted in the middle of the chassis because the pulley fits up tight in there?
Title: Re: ARMA super mod!
Post by: jerb on October 17, 2010, 08:19:40 pm
thanks Ryan, yes using an 8'' pulley on the ragb, not alot of room, i mounted the ragb back farther so the pulley is gonna be real close to the tubing that runs from side to side across the chassis, might have to do a little mod to that tubing, i honestly forgot about the tube till i looked underneith, oops, my bad...lol, lots to think about when building these chassis, like you say you must look ahead when building!
Title: Re: ARMA super mod!
Post by: monkeyward71 on October 17, 2010, 10:55:24 pm
so if your running an 8 on the ragb then an 8 on motor??? is that just for added belt contact or something special?
Title: Re: ARMA super mod!
Post by: Jeff Digou (Pitguy) on October 17, 2010, 11:11:38 pm
I am thinking   4 or 5 on the motor    1 to 1 don't sound right ;)
Title: Re: ARMA super mod!
Post by: jerb on October 18, 2010, 08:27:18 pm
the plan for now is to run an 8 on the ragb and a 5 on the engine, if it was an 8 on the engine, you would have to run a huge rear sprocket and a tiny front sprocket to get your final gearing low enough for the relatively short tracks we race on! I like to use as big of sprockets i can on every build to improve belt wrap and lessen the chance of slipping which creates heat and kills the belts!

lol well ok, sorry went back to kart basics of just naturally having one ratio to worry about lol. for example we ran as low as 10 driver and 73 axle, turn like 7500. but geuss everyones got there own prefferencs lol

i could run 1 to 1 ratio, but good luck finding split sprockets for the 40 series chain, i havent seen to much above 60 for the 40's chain, i could run a smaller front sprocket but with a 7/8'' shaft on the ragb, 12 is the smallest i have seen or could really build, if you could actually overdrive the ragb it would probably be better, but them ragb's are built pretty stout....and i plan on revving the snot out of the intek, well the 2nd one that gets built, first one gonna be on the real mild side....lol, till the money catches up with the brain!

Very nice Jerb  

Also  picture  009-2     could you have put the bell crank in the center and had your arm come down straight instead of putting it on the left side and using angles ?   
Title: Re: ARMA super mod!
Post by: jerb on October 19, 2010, 08:51:20 pm
would of been easier probably, but this way all the rods stay the same length, not sure if that matters but....the way it is now the bellcrank is exactly in the center of the front wheels, if i tried to make rod straight up and down the steering would have been backwards, so has to be at an angle with this setup with steering in rear....

Thank you George, only thing, might have to figure something else out for a pulley on the pull side of the belt, will be fairly short belt so maybe wont need it for slap in the belt!
Title: Re: ARMA super mod!
Post by: George Herrin on November 01, 2010, 12:15:22 am
Should not need it on that short of belt. I am using just a single pulley clutch and I do have the idler on the pull side but it fell off once and I got no idea how long it run without it cause i only found it when doing a service. I run a 56 or 57" which ever they have when I buy them. I prefer the 56 with the centrifugal and the 57 with the manual clutch. Either works well with my setup. My manual clutch is also cable operated. When I use it. I carry it and cable and pulley in trailer in case my clutch fails can change it over in about 10 to 15 minutes.
Title: Re: ARMA super mod!
Post by: jerb on November 01, 2010, 12:19:49 am
what did you use for a cable, i was thinking of just making one with some 3/16'' steel brake line and using some small cable inside of it, i have a cent clutch im gonna put on it, just for kicks its a cheap one and might see how long it will last, but plan on the future on getting a star clutch!

I would have to agree with Ryan on the rear wheels. I have run the twins with both the 8"hoosiers and the 6" burris. Traction is better with the 8" setup. Its also a better (smoother) ride by far.

any early 90's ford cougar with a big block 429, trick flow heads, 20% over-driven 8-71 super-charger, enderle mechanical injection setup for methanol, 31-19.5-15 rear hoosiers, been a shop project for a few years, we have started it a few times but still not done with running gear, have to post some pics sometime, after we clean all the junk off of it....lol

Hey Jerb, when turning full left do you have lots of swing before the tire gets into the nerf bars with the offset? hard to tell in the pictures.
Title: Re: ARMA super mod!
Post by: jerb on November 03, 2010, 10:28:26 am
thats one bad ride Ryan.....as for the nerf bars, when i turn full left i have about 1/2'' of clearance!

got the clutch done....still need to add the belt guides and finish up the cable for the foot pedal, was able to use the dual pulleys and a 60'' belt

Post by: jerb on November 06, 2010, 08:40:24 pm
the clutch is just a simple push and pull clutch, i like them better than a single pulley clutch, ill get some pics tomorrow of it disengaged, it is built super heavy duty, with a 1/2'' bolt riding on sealed bearings...

Nice build. Did you key the shaft for the drive sprocket?
Title: Re: ARMA super mod!
Post by: jerb on November 07, 2010, 09:35:10 am
yup, its a 7/8'' shaft coming out of the ragb, so i built a coupler and then keyed some hardened 7/8'' shaft with a 3/16'' mill bit!
Title: Re: ARMA super mod!
Post by: jerb on November 27, 2010, 04:19:47 pm
Had some time to work on this thing...got the clutch done, i used 3/16'' brake line and 1/8'' cable to actuate the clutch, this will be somewhat temporary till i get a noram cent. clutch..
(http://i272.photobucket.com/albums/jj163/jerb-2008/th_019.jpg) (http://s272.photobucket.com/albums/jj163/jerb-2008/?action=view&current=019.jpg)

also got the axle and bearings along with the 3rd bearing installed...
with 16x7.50-8 tires it sits at 2'' in the rear, i need to change around the front spacers to get the front end just a shade lower as it sits about 2 1/4 right now....officially a roller i guess!

i was hoping for 2 1/4'' front and back but evidently im getting worse at reading a tape measure....i think if i lower the front just a tad the rear should raise just a tad!

Post by: fordman21 on November 27, 2010, 08:22:38 pm
I used to have mine down to 1.5" in the front but raised it up to 2" to get it to handle right for me. I think my current machine is around 2 1/4" in the back depending on tire pressures.
Looks good Jerb, I'll bet its nice to have it on four wheels for a change.

I bet driving one of these mowers is a blast. We're just getting started and ours are still at stock height. We pretty much have to roll through the turns if the track is sticky. Looks like you got a great machine in the making there and I bet it'll handle great.

Erick was planning on building one, but not sure now, he talking about building a nice engine for his mod-x, and yes im anxious to get some seat time on this mow-chine, should handle awesome, ive had the ole mod-x on 2 wheels more times than i like to remember, and it was 4 1/4'' off the ground so im looking forward to driving this thing all out! and as far as i know we both planning on springfield!

With turf tires on the back and a mild motor combo  you will be fine for now.  When you build a engine, i would change to racing tires on the back. WOO supermods run mild engines with turf tires and do just fine.

well got married, bought a house, new job, and finally can afford to build the mowchine i been wanting too, and of course with the wifes permission, its super mod time, no local club no more but plan on maybe all american this year and few big races next year, pics to come fellas!!!!

raised the fenders up about an inch as well, so as it sits have about 1 1/4'' clearance, built everything with mower tires in mind but my plans changed...lol
