Looking good Matt!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Probably would be easier to bring your truck to my shop! :lol:

Thanks man! Between you and Dieselwrencher I want to bag the rear of my truck too :dohh: But i gotta get this hoe running.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Got the two other pieces cut that I need to cut for the driver side of the frame.

http://i167.photobucket.com/albums/u...psba674bb0.jpg

Got one on the passenger side cut and fitted into the frame, have one more cut out for the passenger side still needs fitted and the last one still needs cut out and fitted. Going to head back to the shop here soon.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

And here are the last pieces cut and fitted.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Better get to burning wire, son.

also, i hope you trim that rec. tube. itll get all in the way when you bag the rear hangin down like that

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Ive tried to tell him but he doesn't listen... lol jk matt

BTW Ryan quit putting ideas in peoples heads! haha

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

;)

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Im going to need more wire :lol: and yes I will probably be cutting down the receiver tube. Wasnt really thinking about it seeing as there is 10 inches between the bottom and the pumpkin, but there is not really a need for the extra.

I dont listen to people who dont mess with their projects :mm: :lol:

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

bazang!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

LOL I was waiting for that!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I figured if I keep giving you enough **** you may actually do something with one of your projects other than change oil... :lol:

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Looking good Matt! Next you need one more turbo, one more clutch disc, and no rear leaves. Haha :mm:

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I think i need an engine rebuilt first!

Well first up my shop is a mess!

http://i167.photobucket.com/albums/u...ps23f00835.jpg

I then drilled all of my bed bolts through the bottom of the frame as well.

http://i167.photobucket.com/albums/u...ps26afd9ac.jpg

And I finally got my plates all tacked into place.

Now to just sling 32 feet worth of weld bead at it!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

You're not done yet? :lol:

So, did you tunnel all the way to Iowa from Kansas and get one of my air bags today, and that's why you're not done welding yet? :lol:

And weld those extra holes shut son!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Hell no!

And yes I did, but you came in right after I grabbed the first one so I couldn't steal the rest. :lol:

HELL NO. Do you know how many holes are in these damn frames?

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

So today I bought one of these.

http://i167.photobucket.com/albums/u...ps520ded84.jpg

And did this to it.

http://i167.photobucket.com/albums/u...psc4c3a631.jpg

And it makes a shape like this.

http://i167.photobucket.com/albums/u...ps5b88ac64.jpg

and that is all you get till the next update. :lol:

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

:lol: I like your little tools to hold the metal together!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Looks sweet, those little clamps look handy. now.... why didnt you have that broke wherever you had it sheared? i suggest some inside and outside weld on that baby on the bottom of the tank. and clean the shaz out of the joint area. get all the black surface coat off the edges where you are gonna weld to make sure it is a good weld so you dont have leaks in the future
Ryan

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Yeah the clamps are apparently for making picture frames they seem to wrk tho! And I didn't have it broke because I'm young and dumb and didn't think about that. Apparently I like to make things harder on myself. I planned on welding the bottom inside and out. Know of a good coating to put inside one of these bad boys?

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Also having it broke would have taken two sheets of 4x8 with the size of this tank.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Young and dumb huh? been there done that, still have 50% of that issue

Picture frames, gas tanks, its all the same thing. i have looked into some coatings. still have not decided for sure what i am going to use. KBS is supposed to be good **** and so is Caswell

so! you should just get charged for the area used, at least thats how we do it.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Hmm that KBS is interesting. I may use that or wait till you do your tank. My tank probably wont be fully done for a while. Should start taking some shape tomorrow tho.

I did not buy the steel from the guy that sheared it for me. It was cheaper for me to drive 30 mins away and buy the steel then take it to him to shear it. He asked me what I paid for the sheet and he said he cant even buy it for that cheap so thats why I only wanted to buy 1 sheet.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Well today I finally was able to start messing with the tank. I got it all tacked up and test fitted it. But now the tip on my welder is warn out so I cant weld it anymore till I go pick up more tips.

http://i167.photobucket.com/albums/u...psb599761c.jpg

Seeing if the baffles fit, still have to cut holes in them.

http://i167.photobucket.com/albums/u...ps7845fcff.jpg

Also had the front clip on to check for tire clearance and took a pic of it.

http://i167.photobucket.com/albums/u...psf540423b.jpg

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Looking good Matt! Make sure you get a package of tips and an extra roll of wire for back up. :lol:

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I have gotten the baffles and the sump put into the tank today. I am working on getting this bottom half all welded up so that I can check the bottom half for leaks.

http://i167.photobucket.com/albums/u...psa79451aa.jpg

http://i167.photobucket.com/albums/u...ps396981c1.jpg

http://i167.photobucket.com/albums/u...psad2700ae.jpg

Need to then start mounting the tank before I go about adding the sending unit, filler and all of the fittings needed for the fuel tank.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Looks good! I like what you have done to the truck so far! Can't wait to see how the tank turns out.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

How do you plan to check for leaks?

Ryan

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Thanks man!

We have a big water tank that we are going to push it down in (if we can) and see if any water leaks into the inside.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

No bueno my friend. on a molecular level, water is bigger than fuel. you may not see a leak if you water check but still have a fuel seep. this is a lesson learned the hard way. pressurized with air is the only good way. if you can seal the tank well and put a few, only a few with a square tank, psi in it and submerge it you will be mo betta. another way i like is to weld it all solid and cap it all off while its hot. let it set overnight and if it has a vacuum in the am, you are good.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Well shoot. I didnt want to weld the top on yet without having all my holes for everything in the top drilled yet. Guess I will have to drill all the holes after I weld the top on and try to keep all of the shavings out of the tank.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Ok I guess I understood my dad wrong, he said turn the tank over and trap the air in the tank and push it under water. I guess we will probably try that and if it doesnt work then I will weld the top on.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

that is better, but youll want some soapy water to spray the seams with. i doubt youll be able to totally submerge that tank. that is a lot of buoyancy.

ryan

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Something tells me with Matty, there will be a tractor and loader involved at the least. :lol:

When I check tanks and stuff, I use a pressure regulater and soapy water like Ryan mentioned. I also learned the hard way on water while testing an oil pan I modified................

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

That is the plan!

hmmmm.... now you have me thinking. :lol: I dont have a tank big enough to test this tank in unless I go up to my uncles and use his cow waterer, but that tank is nasty. I have a couple tarps laying around and the bed of my truck.... And yes I have a tractor so I could use that....

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Before underground storage tanks for gas stations are set and buried, they are pressurized and a pressure gauge is installed. Simply let it sit overnight and see if the pressure dropped. No change means no leaks. If it's good enough for fuel in the ground, should be good enough for a truck. I would use a decent 0-10psi or similar gauge and pressurize to 10psi. Spray seams with soapy water.

Also, Ultra Low Sulfur Diesel fuel is very nasty on steel, causes it to rust pretty bad over time. Don't know why, but I would think about a spray on coating designed for fuel tanks. I'm sure there's something out there for this application.

Awesome build thread too!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

40 gallon of air at 10 psi would probably blow this damn tank up. I plan on getting a coating kit for the inside.

Thanks man!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I did get the tank all welded up yesterday, but stopped there cause I think this changing weather is starting to make me sick.

http://i167.photobucket.com/albums/u...psb4074db7.jpg

Waiting on a bunch of parts to come in for the tank. Pretty sure I have everything figured out but going to wait to put the fittings in the tank after it is installed so that I can make sure I have clearance for everything. I have also decided to put the filler in the bed. I dont haul to much stuff and we bought a 16 foot trailer a couple months ago so i should be good to go with that. Plus me and sheet metal are not friends so there is no way I could move a fuel door to the back and make it look good.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

You could move the door, just tack tack... tack it in.

Yeah the one time I did some body work cutting out pannels I messed it up bad. People may not like the filler in my bed but doest really matter to me. Works for me!
