Randy, is the to do list getting shorter or is it never ending. LOL. I sort of forgot, have you got a winch on it yet? Maybe put one on both ends. Add to the lower center of gravity.

Char: I have several different winches I can put on it but the install is down the list. The list is getting shorter but things keep popping up as I drive it. My Temp gauge just quits sometimes, and it will come right back when I turn the ignition off and back on so I don't know whats going on with that. Also my EGT is useless as it reads all over the place or zero most of the time. All the rest of the Gauges work fine. I have to take the Steering wheel off today and tighten the screw that hold the turn signal lever in place.

The Weather stripping will be a major upgrade to the comfort level as it will cut down on Interior Noise alot. Just putting that piece of carpet in the back cut down the noise alot,,, and made me think I probably need to spread some Dynamat around the cargo area. I've got plenty, and right now it is on the Firewall and Floor back to the step behind the seats.

On the Front Bumper I have 4 longer bolts in the center 4 positions and they are there to be used for the Eventual Winch Mount for a Warn 8274. I have two of those and one will make it to the Jeep. The other might end up on my trailer.

Now that the Jeep is drivable it obviously is more fun to drive it than work on it, but driving exposes the weak points and makes more things to do on the list. And the list goes on!

I'd think the gauge issue would quickly move to the top of the list. Intermittent or useless data coming from those can be dangerous. Either you have bad ground, bad sensors, bad gauges, or a mixture of those. It may take a year or two for all the issues to show their faces.

These are all "Isspro Gauges" and the 3 primary ones OP, WT, and EGT all have 'Amplifiers' which may be the problem.

OP, no problem, WT just quits then starts back up when power is interrupted.(turn key off, and back on.) Reads accurately when on.

EGT is useless. all over the place sometimes at 600 then 300 then zero all over the place with no rhyme or reason.
I have to get with the Isspro Engineer to help fix it. I think it's a bad probe or maybe the amplifier? Just one more thing to weed out.

Working on finishing the doors right now and will get back to the Gauges a little later.

I tweaked on the doors and windows yesterday and got them to fit the holes pretty close. Now they open and close and latch right. That made a huge difference and Weatherstripping will finish that off nicely.

The weather stripping will be "Unique!"

I took the Steering Wheel apart today and tightened the Screw holding the turn signal lever up, also found I had not fully tightened the actual Steering Wheel Hub??? oops ,,,, That is fixed and everything is fine in there now.

Probably gonna do Dynamat on the Cargo Area Floor, it would be quick and easy to do and cut down on the noise some more. I also really need to find /make a different Pulley to run the A/C So I can use the Big Fluidampr, Vibro Damper I have, as there are some regimes of engine speed that still vibrate more than others. The entire body is fiberglass and it does buzz around at low idle and about 21-2200 RPM's . Not horrible but something that can benefit from some fine tuning.

Plenty more to do.

My Isspro gauges started giving me problems in less than a year. Quickly got tired of messing with them and went back to gauges available in stock at the local Autozone. Don't remember the brand and model. 37 states later, they are still working.

I've been having ISSPRO EV1 gauges in my 1998 Dodge since 2014. The EGT and boost (mechanical) have worked without a problem. The mechanical fuel pressure gauge is a different story. The gauge itself works fine. The issue I've had is the 1/8" tubing between the isolator in the engine compartment and the gauge in the cab must be kept liquid full (no air bubbles) with antifreeze/H20. Over time, the tubing develops air bubbles. It must have a very small leak somewhere, but it is too small to locate. I will probably replace it with an ISSPRO EV2 electric gauge.

I tried to come up with a cure for the ac pulley arrangement but no success outside of making a custom pulley. The factory accessory pulley works fine but was never used with the large harmonic balancer. That came on marine and industrial engines that didn't use ac. The vehicles that did use it with ac had the fan mount in a higher position. One possible was to use a different fan hub like the commercial engines had. That would move the pulley to a slightly higher position but then there's the mechanical fan problem. An ideal situation would have been to engineered your ac compressor mount so you could drive it off the same 8 groove belt. Can be done because I've got one on my work bench but it ain't simple. Requires a reverse fan pulley which would mean your mechanical fan wouldn't be right. I worked that out too but it means a whole different fan and clutch assembly plus a custom adapter. Below is a photo of the fan hub assembly I built. Only part that hasn't been done is the fan mounts. Had them designed and roughed out but other thing have gotten in the way over the last few years.

Those look nice Char, I don't see any other way but to make a pulley, and changing it out will be a real PITB. It was a Real PITB to install the fan when it was on the engine stand out of the car. In the car it will be real Hard ! Luckily I have another Fan mount I can test it on so I don't take it all apart and not have it fit right. Getting the 4 Screws started is the problem. There is virtually no room to access them. It will be lots worse than this.

Making a new pulley was about the only answer I could come up with. How much smaller diameter does it need to be to clear the balancer? I have several different fan hubs in my collection. One is the 91.5-93 Dodge hub that puts the fan in the center of the block and at a slightly higher position. That one wouldn't work because the V belt pulley doesn't fit it and would be in the wrong alignment. One possible is an industrial hub that mounts to 4 bolts on the head. The accessory pulley can mount to that one but the hub bolt holes are 10mm in a 60mm circle instead of 8mm in a 50mm pattern like the stock 4bt. That could be done by simply adding the smaller bolt pattern to the hub. There was even one with the 50mm pattern but that sucker has no internal bearing. I've never figured out how that thing can possible work. No place for a grease fitting either. Just the metal shaft in a cast iron housing. I've looked at that one for years trying to figure out how that could possibly work.

I can't remember how much smaller it has to be I think I remember about 1" smaller than what it is now. I'll check and get back to you, Also these belts are "B" Belts which are the next size up from normal Vee Belts.

After some searching,,,
The Big Damper is 9.75" and the one on there is 8" 1.75/2 = 7/8 so 1" smaller on the A/C pulley will work.

On another note" I installed Dynamat in the Cargo area last night and topped it off with a piece of some gray carpet I had laying around.
The carpet is temporary as there will be a set of drawers in the cargo area up to the top of the wheel wells and carpet on top of that.
That way the Batteries and Air Compressor will be closed in and it will also provide a hiding place for a shotgun! Pretty serious about being armed when in this one, as it does attract attention..

This proved to be well worth the 3 gallons of sweat I generated while doing this!

The test drive revealed more improvement to the noise issue.

Dynamat gave me tons of product, and most of the inside of the body is done now.
I have some lightweight material they provided to use on the underside of the hood which should cut down on the external noise some more. May do that tonight or soon.

All the stuff I'm doing right now is utilizing stuff that has been laying around my storage area for years and I am now putting it to use. Everything I do is improving the Creature Comforts in the car and making it more pleasant to drive.

I have to tell you the Big GM Seats were one of the best things I did on this build. So comfortable.

Been doing a few piddly things to the Jeep over the last week or so.

My big accomplishment today was putting Dynaliner on the underside of the hood.

This stuff is made by Dynamat but is a completely different animal. Dynamat is "essentially" a sheet of Aluminum Foil with some kind of Tar stuck to one side. That is also the adhesive that keeps the stuff stuck down. I have applied it to virtually all of the interior of the Jeep. Less the Wheel Wells and Insides of the body behind the seats/doors.

This other material is essentially a Closed Cell Foam with adhesive on one side.

I had to remove the hood ( Friend Required) and clean it thoroughly with Oil Eator to remove any traces of oil and chopped up bug guts. That Big Fan slices and dices anything that makes it thru the radiators and deposits it on the underside of the hood and wheel wells.

They gave me 2 sheets of the 1/2" thick material as one wouldn't go all the way across the inner hood. We laid out a center line and put the material down from the center out, and then trimmed the edges flush at the outer edges of the hood after it was all stuck down and rolled into place. I made a Roller out of a Skateboard Wheel a few years ago when I did the interior of the car. It was put to use again today.
I had some Aluminum Tape that is used for heat sealing ducts and things like that and we put a strip down the center line to hide the gap between the two side pieces

It came out fairly well, but a Test Drive to Ventura Showed me that it was well worth the effort .

Significant reduction in Interior and more properly Exterior Noise!!!

One other thing worthy of note was I managed to install a "Hide a Key" on the Jeep with a spare set of keys in case I get hijacked or something. It only took me two days to find the one I've had for 25 years just waiting to get used on something.

I know all of you are familiar with the little Key Boxes with a magnet to stick a Spare Key in your wheel well or where ever. Well on this Jeep that magnet wouldn't cut it. It would have vibrated off in a matter of minutes.

I had some "Rare Earth Magnets" left over from a Navy Job I did once, that are little pucks 1/8" thick by 1/2" in Dia. The Magnet in the Hide a Key was glued in a steel socket and the glue gave up so I just stuck 4 of the pucks into the cavity.
Just the Magnetic Force alone keeps it all together and you practically need a Screwdriver to pry it off the Jeep.

Sorry You don't get to know where it is! And you'll just have to Imagine what it looks like!

Been Smoking Hot here in Ojai CA and today the sky is full of smoke from various fires burning in NoCal and SoCal. It has been over 100 F for 7 days in a row and last Saturday it was 112 F here and about 6000% Humidity. Now I know what it is like in Atlanta.

Air Quality is non existent. Hiding in the house going broke.

Been cogitating on Weather Stripping for the doors and I think I am going to use scraps from the Dynaliner I used under the hood. It is adhesive on one side and is 1/2" thick so it should seal the gaps. It is also Closed Cell Foam so it shouldn't absorb moisture? Good thing is that if it doesn't work it will be easy to remove as opposed to trying to remove 3M weatherstrip Cement which is virtually impossible to get rid of.

I post some pics when I get able to work on it.

Interesting that you've been in the 100's this past week and here in NC where I live it's been in the 70's. That is not our normal weather for August. 90's would be more normal for this time of year for us. Weather is just all screwed up every where.

Char: it has been stupid hot here all week. Our A/C has been running virtually no stop and our upcoming Electric bill is going to be big. It has been over 100 F everyday and the place is just getting cooked. If you have watched the News Northern CA has been having Massive Brush Fires and it has been overcast with smoke and haze here steadily for days, but still smokin' hot. The southeast corner of the house warps so bad that the rear doors don't close right.

Hoping for some roll back in the Temps this next week? We'll see.

Aren't you guys getting heavily Rained on and Hurricaned? I saw there is two brewing in the Gulf .

Randy, just paid the power bill for last month. $54.54 and that covers the ac, kitchen appliances, hot water, lights, etc. Never been that low this time of year before.

Yeah ours is going to be big! I don't even want to know, because we just got done with 3 days of 112,114,and 116F Fri Sat and Sun. Yesterday was only 95F.

Today it is Pea Soup Fog and probably won't break 75F ? Go Figure?.

I like it when the reason for us to believe in Global Warming and Climate Change is because they are predicting what the temps will be within 2 degrees in 100 years, but they can't even tell us what the temps will be within 10 degrees in 2 weeks!

Gotta love Liberal Academia!

One thing I have known for a really long time and was taught by watching my Dad engineer and build things that couldn't possibly work, is that,,,

"You can make anything work in your head !"

Putting it into the real world is where the problems start!
