I finished the Dzus tabs and primed them so now they are ready to install. I used Rex's suggestion about using countersunk (flathead) rivets for mounting the springs and countersinking the back of the panel for rivets; they are put in "backwards" from what would be considered normal. It worked out just fine- no interference from the pulled rivet bulbs.

I scoured the internet and found not even one procedure for mounting self-ejecting Dzus fasteners to mounting tabs. This forum is a wealth of information. Thanks, Rex.

BTW, eagle-eyed viewers may spy the center punch marks on the tabs; it is to identify which one goes where.

I saw the punch marks.

When it comes to your build I don't miss a single thing.

Always the best learning experience.

Thanks Neil.

You, among others make this forum what it is.

Hey Neil I guess it was too hard to get to your number stamps ? [ chuckle ]

I took the lazy way out, Don.

Yep been there done that, even used a square file to make a notch too what ever gets it done

I've been working on the radiator plumbing lately. Putting a bead on the tube ends does help a T-bolt clamp retain the tube; without a bead it is possible to pull the tubing out of the rubber coupling even with a fully tightened clamp- it just slides out.

My mechanical water temperature gauge required a threaded bung in a radiator tube so I silver brazed on a 1/2" NPT fitting. Now I need to dress the capillary tubing and put on some clamps to keep it in place.

BTW, I had a hard time finding what the minimum bend radius was for capillary tubing. For reference, Stewart Warner says it should be 2" or greater bend radius.

I routed the water temp capillary tubing and finished most of the left side coolant plumbing; now working on the right side. One stainless 90 degree bend must have been cold- worked by the mandrel bend-- I couldn't get a bead on the end no matter how hard I squeezed my home made beading tool. I wrapped a few turns of safety wire around the tube end and silver brazed it on. Not as pretty as a nice bead but it should keep the hose from blowing off.

Still the tidiest build on the forum.
Neil, you've set the benchmark for quality.

[manta22]

Thanks, Mike.

Has anyone used Gates Power Grip hose clamps? They are a heavy plastic sleeve that heat shrinks over tube ends and they replace other types of hose clamps. I ordered some to try on a few of my radiator hose connections but I'm interested in what others think of them.

Hi Neil

Use good old metal clamps that work, don't need no plastic in that place

Let someone else be a pioneer as they get arrows in the fanny

That's all you need is some hot water on your rear tires at 200 , bad deal and could make for a real bad day too

Don;

I don't need no stinkin' scalding hot water on me, either   

Gates has been selling these clamps since 1996; have you tried them?

Neil I have been away from motorsports for years , but I follow it all the time to stay current with the building & racing like on the forum here and your car

Buy the best metal ones you can find, drill a safety wire hole and wire them up and run your car

Forget the trick stuff as you just need the time proven basics, you will have enough to worry about with out anything going wrong  [ KISS keep it simple right ] those are racing words to live by

With 25 yrs of building pro racing engines , I have seen it all from the sound package to the ultra-trick and the trick guy is on the trailer and the sound basic guy is taking home the trophy and the cash !!!!!!!!!!

Neil. Years back I used some ratchet type plastic hose clamps for heater pipes
on a motor. I don't think they were Gates?.

I changed back to the steel eventually. They weren't easy to service so to speak.
I think I still have one or two and I'll take pics.

How do you remove the Gates clamps if you need to?.
