I made a grenade shift knob for an automatic
 
So i have seen grenade shift knobs for sale in quadratech but never for an automatic and for alot of money. I always figured I couldn't do it.

well I was at a local sporting goods store and they had surplus inert grenades for 6 bucks, its the real deal (or so appears) but have had the bottom cut open to gut out the explosives and the hammer taken out and the primer is spent.

well all the stock shifter does is push down on a button to activate shifting, the stock shifter even pulls right off with no twisting or tools.

I had been using a revolver cylinder shifting knob you can see in the creative mods thread on the first page. I wasn't happy with the looks of the shifter and wanted something more jeepy. so i thought i could make the wwII erra grenade work and bought it.

first thing was i had to bore the bottem hole out, it was half the size of what was needed for it to slide over the shift shaft.

then once i got it to slide over I did not like the way it activated the button, it was bindy and rough and did not always push down on the button unless you positioned it right, i greased up the knob with little improvement but at least it would keep things from scratching up. well the top of the grenade screws off and the spoon and primer come out, the reason the button was not being hit all the time was the primer was too narrow and did not give a big enough flat surface to push the button at all angles. so i filled the grenade with hot glue and baked it in the oven with it tipped up on its top to let the glue form a flat surface to let the button push on. http://i625.photobucket.com/albums/t...M/DSCN1147.jpg

i let the glue fully harden and now the shifter works perfectly. all you gotta do to push the button is the push down on the whole grenade and select gear, then release pressure and the grenade will come up and let the button disengage.

i used a dremel with a grinding bit to make the hole larger (don't go too big or the grenade will have some slop, just big enough to slide over the shaft) and I used hot glue because its what i had. anyway to make a wide flat surface for the button on the shift shaft to push on would work. the top originally screws off like I mentioned but I took these pictures after glueing. hopefully my glue idea holds up in warm temps. if not ill bake it out and try putting a wooden dowel over the primer or a different adhesive, who knows.

Are you still going with the same setup?

That thing is da bomb!

YellowJeepGuy94 01-01-2014 12:06 PM

What is the size of the hole? And what drill bit did you use?

If the hot glue doesn't hold up, just use some two part epoxy...any hardware store.

I love this, but I also came across the idea of a cylinder from a .44 mag. Did you just buy a brand new cylinder? That's a little expensive for me haha

I used a beer tap handle, it reminds me to stop at the store and pick-up beer.

Nicely done.
There is an adapter for the auto safety switch, Big Sarge found it somewhere and says it works well.

Made my shifter knob out of a AR15 pistol grip. Looks real cool and believe it or not it is really comfortable.

Really Cool Handle!

How did you make the hole on the tap handle for this? I really like it. Im assuming you just push down on it to change gears?
