Nice work on the manifolds! What are they for?

it's part of a city water purification system

Shooting target, spins when shot. The circles are 1/2 plate; it's entirely MIG welded.

Laid this stack of dimes last night.

that is all.

 

[Farmall450]

I too have one and for the price point I don't think you can beat it. I use the steel cutting blade in mine.

Huh, shop teacher brought his personal one in and it's a huge POS. Cutting 1.5" aluminium square tubing on angles, somehow it caught and cut the lever inside which raises the blade guard when you lower it, spit it out at him...

I'd suggest you gussett the top bar that the spinner spins about. A missed shot or two and the welds or surrounding material will break. The forces on the supporting member of a spinner are pretty high.

Did you flatten the tubing yourself?

Here's a video of my finished DIY fume hood extractor V1.0:

Thanks Ryolse. Good to see it in action. So, since I'm new to welding, do you see the suction being a problem when you're welding with gas? Or would you only use this if you're flux core welding? Thanks.

I cant see the image at work due to filters, but shooting steel plate is dangerous. It is possible to have a bullet ricochet back from denting in the metal.

This is why targets are made from AR500.

Just becareful. I was gonna start making targets and was told to shy against making them from Steel.

Building a new Work Bench for the new Garage...need to get going on the 1/8 thick Stainless Top and .100 6061-T6 Peg Board back and sides.

Yes, just used the shear at school
It's a lot easier than notching them. Not a bad idea, I guess that probably is the weakest link.

 

[jerseykat1]

Sadly I still have not finished it. Have not worked on it since summer 2014.

I don't plan on shooting this with rifles so I should be OK. Definitely will be careful.

A while back I made a new stand for my tube bender, then removed the handle and replaced it with a trailer jack:

It's the portable welding fume extractor that I was mentioning above.

http://www.garagejournal.com/forum/showthread.php?p=5335120

Basically a cheap version of this. Total additional cost out of my wallet came to $40 since most of the stuff I already had.

Where do the fumes go? The commercial units have special filters to catch the harmful particles.

The velocity isn't high enough for it to be a problem. When I feel like spending the money V2.0 will use a higher efficiency centrifical fan that won't stall out like the axle propeller blades.

Where do the fumes go? The commercial units have special filters to catch the harmful particles.

There's a filter 22x22 filter that slides into the top. It's not as great as the $200 HEPA filters that the commercial/high end DIY builds have but it was better then using nothing for now until v2.0 gets built.

 

[toofart]

Cool, nice work

Did this project a while back, but here it is. I made some traction bars for my 2nd Gen Dodge Ram. I got rid of the axle hop.

Welding project complete, ready for the machine to be mounted. Looks like a good weekend for that to happen.

Those types of traction bars actually bind your suspension, becareful towing.

I have never had an issue with mine. At its price point, I wouldn't choose another tool. 4x6 band saw is slow and equally as big of a POS and cuts so slow im drunk before I can get two cuts done. Abrasive saws make my cuts look like i was drunk before and after the cut however I usally have to get drunk to ease the pain of using the saw; drifting cuts, loud, dirty, and miter cuts are really a joke .


I have been looking for a used scotchman cold saw but the only ones I have found in my price range are missing allot of parts. Until then the rage gets the job done.

Great job on the fab and welding. Just for future reference, welding mild steel to drums and disks tends to be problematic as the weld tends to crack at the boundary. With the hydraulic it won't be near an issue as if you were manually bending but just something to keep an eye on.

 

[sanddan]

There's a reason these tanks are machine-welded. Too much at stake to rely on humans. Would you buy a tank that was human-welded knowing that your safety is at stake? Food for thought. I'm just concerned about your safety. It's one thing for a weld to fail on a machine stand. It's another thing if it blows up on your face when it has 100psi in it.

A machine weld isn't inherently better than a human produced weld. If all of the parameters were set correctly and tested to be correct the machine weld will be more consistent from tank to tank (if the prep to the raw steel and part setup is also consistent) than a human welder. That said, air tanks and other pressure vessels were built for years before robot welders were invented.

Another point, was the tank manufactured in China? So many items now days are and if so they most likely were welded by some guy in a dirt floor factory using questionable processes and materials. Not confidence inspiring either.

I personally would not modify an air tank but I'm chicken and there are lots of things I won't do. I assume the OP hasn't had an issue so must be a pretty good welder.

Those types of traction bars actually bind your suspension, becareful towing.

Yeah, need a shackle or slider maybe.

I did heat up the disk before I welded to it, I don't know if that helped or not. I did the same thing when I welded a stand out of a flywheel, torched the flywheel until it was good and warm before welding to it.

It's still mechanical (you put a drill to the end of the jack) but I haven't even bolted it down yet, it doesn't move while bending.

Actually no they do not, as long as there is a shackle at the back of the leaf spring that will move back and forth.
They may not be optimal, too long and mounted too close to rear end housing but with pivot at both ends do not bind.

 

[csp]

Sure they do! The change in leaf spring length as it flexes isn't contained to part of the spring that's behind the rear axle.

As the springs flex wheelbase changes. The rear axle moves fore and aft. Traction bars like that limit that movement unless they are mounted at the same angle as a line drawn from the front spring mounting bolt to the center of the axle.

 

[vintagespeed1956]

...Traction bars like that limit that movement unless they are mounted at the same angle as a line drawn from the front spring mounting bolt to the center of the axle.

this is true. those long traction bars will bind, but i doubt a big ol dodge is going to flex enough to notice.

a fix is to mount the front of the traction bar to a swing shackle in plane with the front driveshaft ujoint. allows full droop/compression and doesn't bind, you'll need mounts above and below the axle centerline to stop any rotation when the leafs wrap.

edit:

for posterity's sake; the shackle should be the same length as the leaf shackles and mounted via a JJ or "uniball" pivot to allow for twist.

 

[nick366]

Any binding that may exist has gone unnoticed by me even in towing situations. Towing bumper pull 14+k pounds, the truck sags ~3'' or so with air bag helpers. The bars could still be rotated on the heim joints by hand. I'm happy with what they do but don't feel a need to change them up for the time being.

 

[pepi]

I like the holes chewed in the mounts for the bars, looks like there is enough slop there to keep things from binding LMAO.


@vintagespeed1956 It is the well it works for me, never mind the facts.

 

[mrolds88]

What he has is a simple 4 link. no binding. Now if he would have built a ladder bar type unit, then yes it would bind. The ladder bar would create an arc not conducive of the arc created by the leaf spring suspension system. It is really no different than what GM has done on their A body cars with the coil suspension for all those years.

Nice work. Kudo's on doing it with a torch. Most here need to do cad drawings for weeks, then have the pieces laser,water jet, plasma, or milled.

Ditto, you beat me to posting the same thing. But the people who don't understand will still think it will bind.

Wow, that is really nice pepi!!! I could see that as not only a great welding cart but a base for many a smaller machines. Drill presses, tapping, especially with the pan type top.

 

[bluebolt]

ISP is correct, those tractions bars can cause binding. To see how much you would need all the measurements and angles of the suspension and bars. When it binds it would rotate the axle slightly which would also rotate the leaves slightly.
Since the purpose of these long bars is CONTROL the rotation to stop wheel hop if done correctly it has shown to be beneficial. Ford Lightning F150 long bars which are 58" long have become popular.

A shackle used with this system would make it dead weight. It would no longer restrict he axle from rotating.

It is NOT a four link, to do that it would have to have a pivot between the leaf spring and the axle. Such a pivot is used in some race cars with leaf springs and ladder bars.

The success of these long bars has a lot to do with suspension travel, the less the better.

toelesswelder, how do you make the pie cuts and have them come out so well? Are you using some kind of sled on an vertical bandsaw? Please show pictures of your procedure if you have them.

Thank you.

This is correct. The "pivot" mentioned above is actually called a Housing Floater. They are common on Ladder Bar set-up when using a Leaf Spring in place of a Coil Over.

Once you "pin" the housing to the Frame the Housing needs to be able to "slide" forward during extension and rebound on the Housing Floaters because of the Swing Radius created by the Bar. However the longer the bar the less effective bind.

i can take some pictures. but i divide the tubing in half, draw a sharpie line along each side of the tubing. and i just clamp a piece of angle iron on the band saw so each pie cut is the same length. i just keep turning the tube 180 degrees and line up the sharpie mark on the angle iron with the tubing mark
