As I say I like it too but it sure is $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$!! Can't imagine what it would cost to fill a block w/ nowadays.

I did exactly that on my 230 inline 6 head! I cast up '180 deg', isolated runner aluminum 4-bbl manifold and used Devcon plastic steel to isolate the siameze ports in the head. I built dams on one side using modelling clay, cut a mesh of window screen as internal support inside the plastic and poured the plastic steel and let it set up. A little grinding w/ a burr blended the ports to perfection. I brazed a rod to the bolt bosses inside the runners to complete the isolation. I used a Holey 390cfm 4-bbl carb. Made equal length 34" primary dual headers. This combo was great, car would climb a rope w/ bottom end torque, great gas mileage, plenty of top end too. See photos of the project in my Journal.

Thanks for confirming that for me Eric. I have always wondered it that was true! The 'super metal' kit we bought was fairly expensive but saved us about $5000 on a new prop and about 2 weeks of down time which would of been many more $thousands.

Many thanks to you and everyone else out there.

ruffrida2005 Eric63M is correct we have them in our "BDAR" kits for when we need them in quick actions. I have used this stuff several times while in Iraq. I'm a 63B which is a Wheel Mechanic and no I dont work on wheels. It's everything that has wheels on it. It is way better then JB weld, but does set up slower. I had to use this when i put a hole in the oil pan of a HMMWV "Hummer", till we could get a new one.

Eric63M Its not trouble from advertising this product. Most of the information on the Bradley Fighting Vehicle is classified at a minimum level of secret but alot of it is top secret. So I'm going to get clarification from my S6 about some of the repairs and see what they say.

Should be able to post most of it, but never want to make that bad decision and ruin what I have going for me.

I'll get back on the repairs and the details (as much as possible), but I can honestly say now that the product will hold until you take it off (With grinder).

I've used it on alot of repairs and saved alot of money and time doing it.

Even holds up under extremly hight torque, 10400 ft/lbs of torque to be exact... once again I'll see how specific I can get but basically fixed a broken U joint.

Eric
I don't know what type of trouble you're avoiding here but it would be interesting to know how the guy 'in the field' uses these products. If it's military type of trouble, I can understand, if it's advertising trouble, you're not selling the product, let the info fly out here! Fixing things that may at one time be tossed is always a good thing.

And this also: Thank you for your time overseas serving our country, God bless you and keep you safe!

willys36@aol.com JB Weld is a consumer quality epoxy. Nothing special but does a good job in most cases. There are many industrial quality epoxy adhesives that are far superior to the JB Weld class of products. I have never used the Belzona brand but I have used Devcon Liquid Steel and I can attest it is an incredible product. Cures much harder than JB or other common epoxies, super strong bond, totally machinable, adequate for replacing broken pieces on equipment, even for repairing stripped threads. It is sold at industrial supply stores and steel warehouse stores.

They also sell titanium, aluminum, stainless, bronze, and ceramic filled epoxies with similar superior physical properties. It is quite expensive but worth the price where you need the best.

Montebrian We have a epoxy that blows JB WELD away too. Its called "Epoxy Putty" its made by Valco Cincinnati Consumer Products Inc.

Valco was also started in 1952, Though the consumer products division wasn't started until around 1990.

Epoxy putty is fuel proof, oil proof, can cure under water. cures full strength in one hour. Holds 18 ft. lbs. of torque on 3/8-16 thread without issue. I have seen it hold up on a cracked catylitic convertor but its only rated for 500 degree's. Also excellent for head & intake work. part number is 710XX636 and retail is $5.90 for 2oz 2 part tube. Of course case price is much cheaper for dozen qty.

It is a very amazing product. The shifter knob on my Super Case muncie equipped 69' Firebird is held on with epoxy putty and its been used and abused with powershifts alot!

Prairie dog I used this in the late 80's on A AMC Eagle Drove over a man hole in the snow an tore off the starter. Broke the block were one of the starter bolts go. Repaired the block and Had the car for 5 more years it worked out great.

belzona

we use it at work for all kids of repairs holds up great used it to patch a sump tank and that was 4 years ago and still holding and the tank has hot water with chemicals in it

ericnova72 Another note on this good stuff, Belzona has been used for years by head porters to repair or alter cylinder head ports and intake manifolds. It holds well, and has to be ground out to be removed if used on correctly prepped surfaces.

scrimshaw I used this stuff once to fix a feathering boat propellor back in the early 90's in mid-atlantic. We destroyed the internal gearing. It did everything they said it would. We used that prop for a long time after. Carry it frequently now since that time especially on offshore work.

IIRC they said on the advertising that every American tank in the gulf war carried a kit for emergency repairs. I remember being amazed at how heavy the products were.
