You're welcome. How things are made or manufactured has always interested me more than the final product so unless I'm working on a patent idea I'm always up for sharing projects & ideas.

The last fab step to do before painting is to drill a hole in the side of the stick for the wire to exit through and then tap the hole for the bolt that will hold on the ground strap (more of this will be in the assembly pics). The concave piece allows the bolt head to have full contact with...

With the shaft bent up and screwed to the base but not yet welded I installed the shifter onto the transmission and ran through the gears with special attention on reverse (fuel cut off clearance) and 1st (winch handle clearance). With the shifter in 1st gear I rotated the top shaft until I...

Thanks for the compliment! Yes, there is a lot more than meets the eye when first seeing the shift lever - looks like just another stock part on the outside. I'll be uploading more pics today of the final shaft after welding plus a few more fab steps.

Thanks for the compliment - much appreciated

To bend the contoured hollow shaft I used the same method I used when making a set of twin stick transfer case shifters for my brother's Ford Highboy - the only difference being his sticks were solid stainless and my shifter is hollow carbon steel. The bends on my 813 shifter measured in...

OK, so now we have a grenade with a micro switch which will provide a ground signal for a relay in order to open the relay and allow current from the battery to flow to the jake heads. So how do we route that pesky ground wire? I went overboard in an effort to avoid an external wire and zip...

To completely finish the work on the grenade before final assembly I had to trim the ears off the spoon so that it would be free to pivot about the cotter pin when getting the squeeze. After this photo the grenade got 9 coats of matte clear enamel to build up some protection against a sweaty...

The next pieces needed to mount the grenade to the shift handle is the thread adapter and a jamb nut. I had the adapter machined from brass with 1-14 external threads and 5/8-11 internal threads and about an 1/8" shoulder. The jamb nut started life as a typical hex flange nut and then I had...

I found some more info from the Jacob's literature-not Cummins- and it warns of no 25B with divided entry turbo and also when I load the CPL 0026 the application guide points to model 425A which has no warning about turbo entries which makes me think the 425A is more versatile. So would a...

With all the holes drilled, tapped, and a few coats of OD green applied it's now time for painting the description onto the outside. Initially I wanted to replicate the original script that would have read "GRENADE, HAND FRAG, DELAY M26, 5-69 COMP B LOT LS-3" But since this isn't truly a...

First trial fit of the switch in the grenade with the fuse and spoon installed. I used a dremel to carve out a relief in the grenade and I chamfered the corner of the switch but I think one could get away with only doing one of these steps. The switch protrudes right at the center rib and...

The grenade had a 1/2" hole in it top and bottom with the top hole already threaded for the dummy fuse to screw in. Luckily the bottom hole was well centered so to have the best chance at fitting the switch inside I drilled and tapped to the largest size I could while leaving a slight shoulder...

To start with I got a 3-pack of inert grenades to fondle and find out which one felt the best in hand and had enough room for a micro switch. The pineapple grenade was the smallest one and the baseball grenade was a little too bulbous for me but the M26 lemon grenade was just right. Here is...

I just completed my most recent project which was to put a grenade shift knob on the shifter but with a twist. In preparation for jake brakes I wanted to be able to switch the brakes on and off from the shifter like modern big rigs so I went down a rabbit hole to put a micro switch inside the...

Thank you, it took a lot of work to get this finished but it turned out better than I expected. When you pull the pin there is a few seconds delay before...

I finally got my functional jake brake grenade shift knob installed! Just squeeze the spoon and the jakes come on (once I get the jakes installed). I will do a write-up on it in the hot rod section later but I couldn't resist not putting up a sneak peek...

Ok, so here's another question. Can jake brakes with the auto lash adjusters be used on an NA engine safely? I will most likely have the jake heads installed a year before I get the turbo put on.

77 AMG, how is your crew cab conversion going?

Do you guys think that a divided exit manifold combined with a divided entry turbo would not require the special adjusting screws?
