71K5 - BP71K5's Just for fun build

[Greg72]

I like that stairstep metal rack....

I've been throwing my scraps into Homer buckets, but it's not that easy to find stuff without dumping them out every time.

And three rolling cabinets. It's really helped clear up space on my work bench.

Work benches aren't for storage?

The vertical scrap storage is clever ... of course, it occurs to me that the metal place here in town uses one just like it. Not only am I saying "Why didn't I think of that?", I'm saying "Why didn't I think of that when I've seen it..."

With all the rain we've been getting, it was time to clean up and organize my garage so I can make room for other stuff.

This will get wheels next week, but here's a small cabinet to hold usable scrap metal.

Organization is awesome, however my shop is usually only that way just before starting the next project...hell I still got stuff on one of my bench's from painting my bike in Aug 2012..

Me too Greg, that and a couple of milkcrates. Not the best way to keep em, but better than rolling off the shelf or bench onto the floor.

I've been using a milk crate and a homer bucket for that stuff. My new idea for keeping organized is that if it doesn't fit in a cabinet/rack, it gets sold or recycled....So I'm busy building cabinets.

And in other radiator news, the overflow tank was bubbling/ hissing after a bit of driving this weekend. Looks like it spilled a little on the ground, but I don't see anything wrong anywhere. Fans are working and my temp gauge wasn't reading high. Drove it a few more times and no problems at all. I'll be keeping an eye on that.

head gasket or some other leak ?
maybe just a radiator cap?

Head gasket would suck!

Not sure about the head gasket but I did find a leaking joint on the upper radiator hose return port. These radiator issues are going to drive me nuts. Gotta drain it and get it repaired. I've got so much waste coolant in buckets, I'm probably close to superfund site status.

Love the stair step metal organizer. Gonna have to steal that one. It is really hard digging through the homer buckets that are tucked in the corner of my shop. Usually make more of a mess trying to find one piece of steel that "I know I have".

I didn't update this thread with the last radiator repair. Simply put it on my bench and resoldered the return fitting back on. Has been working great for a couple months...



Got back from a Jamba Juice run with my kid and find this...


I'm losing my mind. That is all.

 

[Greg72]

Gotta be a weird torsion problem Brian....

Too much frame flex, twisting the core support...tearing the seams out of the radiators?


My best guess from 3100 miles away.

[AJs72K5]

That's just maddening. Are you running poly or rubber bushings under the core support?

 

[bp71k5]

The latest leak is at a joint on the top right near the outlet for the water pump. I'm fairly certain the previous leak on the hose fitting was just poor workmanship from the factory (torsion would be tough to reach that fitting). This new leak could have been caused from my previous repair by heating up the joint too much, or more poor factory workmanship.

I'm using rubber mounts on top and bottom. I was somewhat resigned to just having to get a real "off-road" radiator from Ron Davis or similar but Gregs comment has me wondering if I should loosen my mounts up some more before spending any money on it. Other option is frame braced engine cage...

I'm just tired of draining the dumb radiator now.

 

[Greg72]

Brian,

If it were me I'd try to come up with a new really flexible upper mounting system... Quite a bit taller than what you have now, with a soft rubber that lets the radiator move as much as it wants to.
Maybe put some modelling clay in that area and then jack up one of your front wheels to see if the torsion squishes the clay?

Not a bad idea. I'll see if I can make something work like that.

 

[bp71k5]

Managed to implement a "trail repair" with some solder and a torch. Only casualty was my welding blanket now has a hole burned through it

Repaired part is the silver colored area above the radiator hose. My fan shroud does seem to be really tight on that side so I'm going to rebuild the bracket with some space to slot the mounts and make sure the radiator can move around a bit even after the brackets are tightened down.

 

[kgblazerfive]

What would be the reason that you want the radiator to move ?

Rubber mounts so it will flex a bit, but not move.

 

[kgblazerfive]

So..... after reading your thread a bit.

The radiator in theory could be solidly mounted to the core support.(not that you should)

It is only going to flex as much as the core support anyway. It is basically attached to it. So it is only going to move when the support moves.

The reason that is is rubber mounted is to isolate it from the vibes on the engine. Not so that it can flex around.

My guess is the issue is not from it moving around to much, prior fixes would be my theory.

 

[bp71k5]

It's a good question. I managed to squish 2 brand new aluminum radiators because the mounts were too tight (according to griffen). The leaks that happened after a few weeks seem to support that theory.

Replaced that with a oreilly brass radiator and that leaked after a few months, but I had it warrentied for the current one that's in there.

Then I dropped some weld slag in the center of the fins and burned a hole in it. After paying to have the hole repaired, it worked fine for a few months.

Then the return hose fitting sprung a leak.

Now the joint right under the upper mount starts leaking. That upper mount I also found to be really tightly gripping the radiator.

thats all the history, but by "move around", I just mean the radiator should be able to shift around in the rubber mounts by maybe 1/16". Right now the rubber is compressed pretty tightly against it so it doesn't move at all and Greg is suggesting that maybe there's something going on other than just bad luck. I'm open to any ideas.

Are your body mounts the same material under the core support as the rest of the body? Meaning you didn't put rubber mounts under the core, and poly under the body...causing the core to flex at a different rate than the body?

Body mounts are all poly.
