🤣 We love ya Bob! We won't blame you!! That's a Ratrodology driveshaft...it's held to different specifications and standards!!!
When I used to make my own driveshaft when I was circle tracking I would put a half a gallon of coolant in the shaft before I welded it up and once the driveshaft was turning it would sling out and balance the shaft. It actually worked really well. Works on the same principle as centrimatic wheel wieghts.
Never too old to learn new tricks.
I might try that thanks man
I sure like that 351M engine you got out of that Thunderbird. It's an engine that never got the respect it deserves. Bought my Ranchero new in '78 with a 351M and still have it. Always started with one key turn and never saw the inside of a repair shop. Put a Thunderbird front end on it years ago and rather drive it than my Vette. Comp cam singing bumpy bump all day.
Been doing my own all my life. A couple of comments.
1. If you do not remove the balance weights on the tube and keep the universal joint end in the original phasing it will be in balance. I have a large tubing cutter that I use so my cut is square .
NEVER TO OLD TO LEARN ANYTHING YOU CAN USE TO BUILD RODS !!! THANKS BOB !!
I have done many driveshafts similar to yours. First cut you off a short piece of the shaft say 3inches, that you can chuck up in the lath, machine off the weld, that makes the end yoke square, then cut the tube square by wrapping a large piece of paper around the tube squaring off the sides of the paper will give you a square line to cut on . Now assemble the shaft exactly as you did. After truing it up and tacking, weld all the way around in one pass then read the indicator. Pour a cup of water on the high side of the weld until it comes back to with in .010 again . You can reheat the weld and cool it if you have to. Some of my shafts have been to 150 MPH without balancing never a single complaint
Well done Red! Good video Bob!
Professor Bob of the university of rat rodology, you are funny you guys got plenty of money oh that is funny. When you have a terminal illness you're poor as poor gets. I still have to do everything the cheap way myself, maybe you could spare your master mechanic for a while. Sure could use ole Red around here got plenty of work for him. Betcha he reads this comment and runs for the hills. Lol well hopefully it stops raining here so i can get something accomplished soon. Like I said got plenty to do but don't feel like doing it.
Stay safe my friend! Red says hi!
That's what I've done more than one time. Yup when you have to make ends meet.
You give us the important details and mo bullcrap. Nice.
Getting there, just not there yet. Thumbs up.
Good one bob i've built at least 20 like that and never had a problem
I’ve cut mine just like that my whole life and I’m 74 years old
I have made driveshafts for years never had a problem.
If you use a hose clamp use a hacksaw. It always comes out straight. Or you can grind up to the clamp.
I’ve done a couple or 5 no problems yet. And I did not check em with a dial indicator. I think it’s gonna be just fine.
good old red stepping in to take the credit lol
Ole Red is such a ham !! LOL
Great video and really helpful.
Man, can't wait to see this truck finished!
I've been doing my own drive shafts pretty much the same way. Pipe cutter makes a very true cut. Never used a dial indicator before though. That's a good idea
Yep .. pipe cutter. I don't have one though!
so glad to see your vids .just can't do any cv update vids so much fear mongering .need more ratrod vids.
Good job Bob , I have done many just like you did it , always come out great .
Just like I said in the last video, waitin on the next. Thanks brother for posting. Hang in there Red !!
Cool video on how to make a custom length drive shaft. Learn something new each time Bob. Looks like red approves this video too
Thanks Bob. Be Safe. God Bless
I did the same thing to my 46 ford truck, except I didnt get it that close. I would recommend getting any driveshaft balanced after welding it up, good show Bob.
I did the same without the dail caliper as temporary, but when I took it to have balanced they said it was perfect, lol,,,l got lucky Bob
Treat your shaft right!
When I cut a drive shaft on my semi we got it down to 12 was the best we could do,the guy at dana said that was better than factory as long within 25tho because the pipe is never perfectly round when it is made
Nice job Bob!
Thanks for showing the correct way to do it. I've been doing them like that for 55 years, never had a problem.
Looks good there Bob. Keep up the good work 👍😎
Back in the 60's I lived in San Diego county and built a few 'dune buggies ' . To shorten the drive shafts we just cut out what we didn't need with pipe cutter or hacksaw then clamped the two ends to a piece of angler iron and welded her up. Never had any problems but we were just running around in the desert not cruz'n the highways.
Thanks for this video Bob! Looks like it may work out great if it shakes it seems a good drive shaft ship could spin balance it for you for a reasonable price.
Nice job Bob. I’ve built a few rat rods in the past and that’s how we did it and had good luck as well. Love the videos and the truck is looking great.
Love the disclaimer. Lol nice work followed a bunch of your projects always watch as soon As they pop up
That's the way its done, been running my 32 ford for 5 years on one.
Thanks Bob.
Great job Bob!
Good Job RED !!!
Good job Red!
Thank you bob i wondered how they do those drive shaft shorting.learned something.
Just remember, it's easier to shorten a Driveshaft than Lengthen it!!!
Keep Rocking!!!
Nicely done 👍
Good advice friend
Mighty fine...Welding there Bob....Thank my friend...!
Great job and Another great video Bob 👍👍🇨🇱
You made it look so easy bob another great lesson in ratrodolgy
Thanks for the tips on how to do that Bob. Have to get me on of them thar dial indicator things so I can try it. I think Ole RED is learning a lot by watching how you do it..
NICE
Thank you for the detailed process. You are good at what you do. It will work perfect.
((😂)) old Reds didn’t sound to happy about it Bob, trying to say he finally got shafted on that deal.. for that deal you may going to have to keep a closer eye out on em ! Lol”😳🌾🧙🏿♂️ nice work Bob you getting after it now 👍🏻
I'm just gone do it lol...love it
Way to "Give It The Shaft"!!!
Rock On Sir Shafts Alot!!!
Ha .... consider everyone .... shafted!
I got no money uncle bob I'll just copy what you and red do can't go wrong god bless 👍🏽🇦🇺👌🏼☝🏼️🇺🇸
Hey Bob good video. You’re getting really good at those hand gestures LOL
Very cool video and project!!!😎👍🏼❤️❤️
I saved this video for later. Thanx!
Those are some great pointers Bob. I've made a few over the years and they worked fine. Stay safe and well
Nice job bawb, i knew you could do it
At $400.00 to $500.00 to have one made I would do it my self first. Like a wise man once said you have nothing to lose. KAG 2020 !
"nothing to lose" - except your kidneys when the front weld breaks and the shaft flings up through tunnel. Or your neck if it hits the ground and pole-vaults the vehicle.
Good deal Bawb! Keep on keeping on brother man!
red supervised the shaft build
Same way I shortened the driveshaft for my f100, no problems so far👍
Holy smokes Bob you've done a lot of work on the frame like welding looks great
I've Done Many a Driveshafts MSelf Bob n Never Hadda Problem Yet Neither Too !! On Model Cars That Is,,,😅😅😅😅 !! LOL,,,, have a Blessed Wknd Y'all.
Well Bob😅got no money can't make it shouldn't build it that's my Saying cause meant to have fun with Hot Rod enjoy what ya do later Bob ya got this thks for sharing
Looks great Bob. I need to get one of those dial-in thingymabobs so I can do mine.
I bought this cheap one on eBay. Works fine .. kinda too much precision for a Rat Rod though. LOL
@@RatRodBobBuilds I'll get one on amazon. Ebay doesn't work well in Canada. Postage costs more than the item.
Great video Bob ,thank you teacher ,and thank you for the disclaimer ! Lol,i don't think you'll have any problem with balance ,since you checked run out ,at only 10th's,i love those dial indicators, thank God i have one from my days of racing stock cars ,i bought Speedway driveshaft (31") for the Imca modified ,not balance ,was off the garage sale ,and not balanced ,i never felt a vibration from it at six k rpm ,so ought to be good ,just remember to grease ,and replace the u joints every now ,and then .Quick question ,any way to cut a carbon fiber drive shaft for a Rat Rod ? I found a good one down at the yard for ten bucks!Thank you,take care Bob
I did my 70 chevelle the same way
I always watch TH-cam on our TV and there's no way to like or comment on the videos I watch. So I have to like and comment from my laptop. But I'm wondering if you and the other channels get credit for me and thousands of others watching it that way.
Anyways great video Bob! and don't forget to practice that social distancing with your buddy Red...
Here is what you do on TV .. well my ROKU anyways. Click on the video while it is playing and you'll see some options ... three vertical dots on the left side .. click on them and you'll get some more options .. thumbs up-down HD and so on. Another tip .... before playing the vid .... click and hold on it and you get some more options ... like ... not interested ... don't recommend channel ... etc. I haven't found a way to do comments yet. Maybe in the future they'll make it happen. I hear ya on the social distancing ... thought about going to the parts store and Red said nope ... order on eBay instead. May have to wait a few days but I have plenty other things to do in the meantime. This will pass and all will be well! God willing!
Hey Bob. I am glad that you posted this video. I have to make a driveshaft for my Fargo. I was going to send it out to a driveshaft shop, but after seeing this video, I think I will try to do it myself. As you said, the worst that can happen is that it will break. One question is why would you not use your chop saw to cut the drive shaft?? Thanks for sharing.👍👍
Man that Red, always siting around doing nothing and bad mouthing poor Bob. Bob, I think your doing a great job, I don't care what Red says.
Looks like you had a fun/late night editin this Awesome video......It's like every process you do, in the Design chair you Redd discuss the plan n then you prep the lay out. Next thang ya know Shazam you gotter done. you have made another Great Presentation on RatRodology....we Love it....:)
And it's not sticking out too far. From the picture it looks as though, it should he at least another 3/8 to 1/2 inch longer.
I didn't show it slammed ... then it goes in another inch.
Bob, but I then have to ask, what about at your typical ride height for when you're cruising down the highway. how far is it out then? I'm sure you won't be cruising when totally in slam mode.
@@jsh3234 It's sitting about ride height in the video. The yolk is way in there well past the tail shaft bushing as it should be. Don't worry ... I got this!
See that the X bracing should keep you from pole vaulting... will you put a hoop in as well ? Kind of amazed nobody has ever made some kind of extendo slip section for high travel applications. Would likely be all they could do to keep up with the 4x4 crowd.
The tunnel will be the only loop ... hopefully it will never be tested. Ha haa!
You probably know Steve Darnell?
The first one I ever cut vibrated the tattoos of my arms...You can't even tell where they were...lol
How important is drive shaft balancing! I know if you are going to Bonneville it must be perfect but if you don”t plan on it turning much more than 4,500 rpm, is it necessary?
Nice job Bob !!! Do you think you'll be turning less than 5000 rpms at 70 mph on the interstate?
69 mph at 2000 rpm's not counting torque convert slip. Remember ... 2.5:1 axle!
Later this year I hope to get started on my 46 one ton. Putting in a 7.3 power stroke because the flathead was junk. Think the original shaft will hold up?
It'll probably hold longer than the rear end.
Bob, On your trianglated rear end do the length or angle of the arms make any difference? Thanks
Scientifically .. yes. The top link should be 70% the length of the bottom link. I use 75% because I can figure that in my head easier. I use about 30 degree angle ... it's close enough for a Rat Rod.
You cut it a bit long cause drive shaft stretchers are a dam expensive tool much easier to shorten it
Red said he use to have one before he got dead!
I kinda missed, "We gettin' it... just ain't got it yet."
Noted ... stay tuned!
Buy one hell no you gotta use junk to build a rat rod or it becomes a street rod, us po folks can't fode that!
You went further than I do, I cut, line the ends up and hang a string along side of it and if it just does touch but ever so slight, then weld... sometimes it they are short I will knock the weights off but none I built ever vibrated none at all and if it did a bit, I check those joints again as one has to be bad. Change em both for ten to worst twenty dollars for whole thing... love ol Red, he don't piss in the corner but you may need a tetanus shot after moving him/LOL
Great tip on the string thing ... don't even need a dial indicator.
Don't blame me if it screws up on ya lmao
Irrelevant from the video but where you from Rat Rod Bob?
Well my accent should answer that but southern Mississippi! That's ... M I crooked letter crooked letter I crooked letter crooked letter I hump back hump back I ... !
Rat Rod Bob Builds yeah go figure, im from California but have family in Hattiesburg Mississippi, watch those armadillos!
