neat tool

[Mike M.]

the c-1(and i'd guess the c-2 and c-3) frames wall thickness is 3/32" thick. numerous brackets(fuel line and brake line brackets to mention a few) are fastened to the frame with self tapping fine thread bolts. oftentimes , the threads in the frame enlarge due to rust or bubba or incorrect replacement fastners. one solution is to weld the holes shut and re-drill. that's a PIA when you discover the hole enlargements, AFTER you've painted the frame. years ago, i built a 57 chevy pickup using a fiberglass cab and doors and front clip. there were times in the pickup's construction where the use of a bolt with nut were physically impossible to mate the nut on the bolt.i bought this handy-dandy tool know as The Nutter. its available from Creative Engineering, 475 miles standish blvd, taunton,mass 02780. the tool installs what is referred to as Rivet-Nut Insta-Thread. one person, working from one side, can swiftly secure blind threaded fastners.what ya do is drill the corvette frame's hole with a specific drill bit, depending on what size bolt you have to use. for instance, if your bracket uses a 1/4" bolt, ya drill the hole with a 25/64 bit, insert the Insta-thread, then using the Nutter tool, the insta-thread is expanded on the unexposed wall of the corvette frame.once the fuel line bracket is installed , all evidence of the Insta-thread is hidden from those sneaky judges eyes. The insta-threads are available to accomodate nut sizes from 6-32 up to 3/8-16. mike

Here is what old Doc Quack is talking about. Brand name is Rivnut. There are other brands, nutsert being one. Works wonders like he talks about

Re: neat tool

Very cool.....Found this site which shows the fastener in action.

p.s. I'd likely use some anti-sieze compound on the bolts to make it easier for the future though.

Re: neat tool

Rich, two very important chemicals on my work bench. NeverSeize and three different grades of Loctite. Another handy product is Loctite Thread Repair. I repaired the stripped fuel line threads in the Quadrajunk on the madam's Corvette almost twenty years ago. Still holding. Add Loctite PST (pipe sealant w/teflon) and there is not much you cannot fix.

PS: Forgot to mentionthat this tool, The Nutter, is not to be confused with The Emasculator sold by Southern States. The Nutter will not convert a bull to a steer.mikie whose just gettin into the Beast.

Re: neat tool

Mike,

This is a picture of the rivnut I used on my 63 frame. Sounds like the same thing and so far has worked very well.

The next one I install, I am going to use a length of thread with a nut to pull the assembly together as opposed to using a bolt because that tends to turn everything and can be difficult to get started..

Re: neat tool

you can get rivnuts with a splined O.D. to help hold the rivit in the hole from turning.....In another life we punched an hexagonal hole in the sheet metal and used a hexagon rivit.....they make an air tool with a threaded nose that pulls the rivit tight....Thanks Mike for jogging the memory.

Re: neat tool

They also have the inserts with a key/tab, that you file a little notch into your hole to reduce the insert turning. These work real nice. We have one of the air tools to set these at work, and they work real sweet, with more consistency over the hand tools.

Mike, the Emasculator is also sold as the following;

Henderson Castrating Tool

Minimizes blood loss and risk of hemorrhage through the severed cord. Utilizes twisting action which effectively closes the severed cord. May be used on any age bull but is an especially effective method to use on older heavier bulls(500 to 900 lbs.) where it is important to minimize the risk of blood loss, swelling and infection. Easy to use and faster than many other forms of castration. Reduces risk of post-castration swelling, infection and trauma. Incise ******* with Newberry Castrating Knife, then use castrating tool with a cordless, variable speed drill. It is essential that only a variable speed drill with a 3/8" chuck be used and that the castrating instrument be tight and secure in the drill chuck. Stainless steel.

Scapel and electric drill work very well as does the rubber band
