Re: Wampus Cat
Welding sheet metal is much different than welding something structural. With welding sheet metal you do not weld a constant bead, just a series of tacks. Otherwise you will end up with a warped up pile of crap. And sheet metal welds will most always need to be ground/sanded flush.

Re: Wampus Cat
Finished the rust repairs around the windshield, drip rails, and inner roof. Applied POR-15 to the top of the inner roof except the ~1/2" wide perimeter where the outer roof mates.
I also started on repairs to the donor outer roof, i.e. work out a few dents, repair rust, repair weakened areas. These are repairs to the rust at the passenger side front corner. |

Re: Wampus Cat
....And these are repairs to the driver side front corner of the outer roof panel. Next up, I'll POR-15 and paint the underside of this panel.
I'm waiting on an order for some sound deadener mat which I plan to apply to the top of the inner roof. Then I'll be ready to bond on the outer roof panel. While I'm waiting on that sound mat order, I think I'll run some some new wiring to the dome light to replace the original wiring that has rather brittle insulation. I also going to fab and install some shoulder harness upper mounting points in the "B" pillars so that I can install three point belts at a later date. |

Re: Wampus Cat
Fixing a couple things inside the cab before I put the outer roof back on:
While I still have access to the inside of the B pillar from the top, I added upper shoulder belt mounting points following the method described in the post -> http://67-72chevytrucks.com/vboard/s...=shoulder+belt My cab did not have a passenger side sun visor, but the donor roof did, so I added in the mounting features on the inside of the roof to use that passenger donor visor when I start putting things back together. My dash radio area was not as mangled as some that I've seen on this forum, but it had been modified at some point in the past with an extra hole and a larger rectangular cutout. I welded in a couple of patches, but still need to re-cut the rectangular opening to the correct size so that the pattern will be hole Ctr to Ctr 6 3/8" and radio-face rectangular opening 1 1/2" x 4 1/2". I also weld plugged and ground flush about a half dozen miscellaneous drilled holes on the face of the dash. (It would be interesting to know what kind of strange stuff previous owners mounted on the dash with sheet metal screws. (CB radios, cup holders, auxiliary gauges, ...... ???) |

Re: Wampus Cat
Thanks kdad. I checked out your build thread. I think we are both headed down the same path of trying to make a daily driver at a reasonable budget.
While I enjoy reading about some of the over-the-top builds that people on this forum are doing, I think I like the daily driver, hands-on builds the most. |

Re: Wampus Cat
Bonding the outer roof back on.
After doing the rust repairs noted above, I prepped the top of the inner roof and bottom of the outer roof using POR-15 and/or primer as appropriate, and then added a coat of semi-gloss black. When painting the roof sections, I avoided painting the approximately half inch wide contact area around the perimeter so that I would have bare metal contact for the bonding adhesive. I applied Noico 80 mil reflective sound deadener mat using a Noico Metal Barrel Roller (both purchased on Amazon) to the roof panels. I chose the Noico because it seems to be less expensive than some of the other brands, and it has little or no smell. I applied it to most of the inner roof for sound deadening and to hopefully reflect some of the Texas sun's heat, but I only applied a few sections to the outer roof to cut down on the “steel drum” effect. |

Re: Wampus Cat
Bonding the outer roof back on, Part II.
After reading the product descriptions and MSDS for several panel bonding adhesives, I decided to go with Evercoat FIB-816 Maxim Large Panel Bonding Adhesive. I chose this because it is a two part, one-to-one epoxy adhesive with a mixing nozzle but it is packaged in a single tube that fits in a standard caulking gun (unlike some others that require a special applicator gun). The product description sheet claims that the adhesive has corrosion resistant properties which I thought was good since the panel-bond-line has to be left as bare metal. Also, the Working Time is 90-110 minutes which is good since I was doing this work by myself and it took the full 90 minutes to apply the adhesive, get the roof in place, and apply the clamps. Clamp Time for the adhesive is 6 hours and Full Cure time is 24 hours which is fine for my schedule. The adhesive application instructions say to brush the adhesive to a thin coat to cover all exposed bare metal, then apply a 1/4” to 1/2” bead of the adhesive to the frame or new panel, align the new panel to the frame, slide the panel to re-position, clamp the new panel to the frame. I had been concerned about how much money I would have to spend on clamps to go all around the roof perimeter, but my brother suggested heavy duty spring clamps that can be found on eBay or Amazon for about $25 for a “Lot of 24 - 6" inch Clamp Large Heavy Duty Spring Metal - 3 inch Jaw opening”. Using these clamps and several 3/8” square wood spacers that I cut from a scrap 2x4, I was able to apply an even clamping around the perimeter, and I used a few C-clamps that I had on hand in areas that needed some additional force. The pictures below show the roof bonded/clamped in place. Next step after the panel adhesive cures for 24 hours is to remove any excess adhesive, prepare the rain gutter area, and then apply seam sealer in the gutter. |

Re: Wampus Cat
Clyede65, Duncan K, SCOTI, ......... Thank you for your kind comments. I get lots of great information and ideas from this forum, so it's great if some of the details that I provide help someone else.
I removed the clamps from the roof today after the adhesive had cured and I'm pretty happy with the results. A couple things to note: While installing the outer roof, when you clamp down on the perimeter, some of the adhesive will extrude out around the edges or any holes. I had put some plastic film between the wood spacer blocks and the metal to prevent them from sticking to any excess adhesive. This worked fairly well except where the adhesive extruded over the top of the film. I had cut strips of the film to go under the blocks, but in hindsight, I should have made the strips larger and formed a "U" shape so that the adhesive would be less likely to extrude around the edges (see pictures). In any case, the wood blocks and most of the film came out easily in about 15 minutes, and I'll only need to spend a little time with a grinder to clean out any excess adhesive from the gutter before applying primer and seam sealer. The film that I used was some material that was given to me from a printed circuit board shop where it is used due to it's non-stick properties. I don't know what it is, but it is very similar in feel to Mylar or Vellum. Alternatives might be a thin sheet of Teflon or maybe even wax paper. I also found that my outer roof did not sit completely flat on the inner roof even after a little massaging. A few areas required more clamping force than just the spring clamps would provide, so I used about 10 small C-clamps in those areas to clamp the two roofs together tightly. I mainly needed these C-clamps along the sides above the doors, and in the area just behind the doors where the rain gutter slants upwards. |

Re: Wampus Cat
Great details on how you did the roof repair. I have thought about doing it this way once I commit to a full on rust repair to my '65.
Mental note to look here for future reference!

Re: Wampus Cat
Seam seal the rain gutter using 3M Self-Leveling Seam Sealer, 08307, 200 mL Cartridge.
After a lot of reading on the forum about people's experiences with various products for the rain gutter seam sealer, I decided to use the 3M Self-Leveling Seam Sealer, 08307. Several people said that they were able to borrow the special cartridge gun for this from a paint supplier or a body shop, but I was unable to find a loaner or rental. I ended up buying the 08307 cartridge on eBay for $37.50 and the 3M 08571 Manual Applicator for $57. I figure when I am done with the applicator gun I'll sell it for $15 or $20 less than I paid for it and consider that a “rental” fee. I had already cleaned up and primed the rain gutter as per the instructions, and I elevated the front of the truck so that the side gutters were horizontal/level. I put some cable ties in the rain gutter drains at the four corners to keep the sealer from running through those holes. And I also put some 3M Masking Tape on the roof side of the gutter, about 3/16” from the bottom of the gutter, in order to keep stray sealant off of the roof. I installed the cartridge in the applicator and primed the mixing tube per the instructions. At about 75 degrees F in my shop, the 08307 seam sealer is about the same viscosity as honey or a thin syrup. It was easy to pump the material out of the applicator gun, and it flowed very nicely in to the rain gutter channel. This material sets up relatively quickly; it has a nozzle dwell time of 6 minutes, a working time of 8 minutes, and can be painted after 15 minutes. The 3M instructions say to “Extrude sealer onto surface, being sure to keep end of mixing nozzle submerged in the seam sealer to reduce the possibility of entrapping air in the product.” I worked my way around the gutter doing this, and got a nice bubble-free flow. A couple things I learned: 1) I used a good quality 3M masking tape to mask around the gutter, but this tears easily if some of the sealing material “sets up” on it before you remove the tape. I found some online video showing the use of 3M vinyl masking tape (like the tape used for fine lines), and I think that would work better for ease of removal. 2) I was working by myself, but I think it would be better if someone could follow you around and start removing the masking tape at the 8 minute point, because by the time you get all the way around the perimeter of the roof, the material is already setting up in the area where you started. This makes the tape removal a bit more difficult. 3) Some people said that they used a different sealer on the gutter area that angles upwards from behind the doors on the sides to the rear of the roof due to the “flow” of this sealer. However, I found that since this sealer sets up so quickly, I could use a “paddle” to scoop or slide the material back up the slope as it began to set up, and very quickly it was stiff enough to not flow down the sloped gutter, but still sufficiently thin to cure as a smooth surface. The “paddle” was just a rectangular piece of plastic material (probably polyethylene) that I cut from a margarine container. The "paddle" is the green thing in one of the pictures. 4) The cable ties that I stuck in the gutter drains helped to keep the sealer from running out, but the drains will take a little more work with an exacto-knife or Dremel tool to open them back up completely. 5) I tried to apply the sealant no more than 1/8 thickness. (As someone else said in the forum, it is a sealant not a gutter-filler.) If you can stay within this thickness, you should be able to seal the gutter all the way around the roof with maybe 20% to 30% of the material in the cartridge left over. |

Re: Wampus Cat
Work Shop Electrical
I finished the assembly of the steel building workshop back in November 2018, and have been using it with just two 100' extension cords running from the house while I worked out the electrical design that I wanted and saved up the dollars. My city electrical permit was approved in early May, and we installed the electrical at mid-month. I ran 220v power from the main panel at the front corner of the house, through the attic to the rear corner of the house, then dropped down the outside of the house to the underground run for the shop. The area where I live is solid limestone, so we rented a rocksaw to trench 24" deep for about 96'. The limestone is fairly soft and the trenching took about half a day. In the shop, there is a subpanel that breaks out two 220v circuits for an air compressor and a welder, and multiple 110v circuits to run outlets all around the perimeter of the shop, switched power to the ceiling for lights, switched power to the ceiling for fans, and non-switched power to the ceiling for drop lights. I also have a switched security light circuit outside and covered GFCI receptacles outside. The install passed the building inspection, and I've been enjoying not dealing with extension cords and tripped breakers for about a week. Next up, back to cab floor rust repair. ;-( |

Re: Wampus Cat
Floor Rust
Somewhere in the past, someone had laid bondo and fiberglass on the sides and front of the cab floor to cover the gaping rust holes. At one point I had thought about just leaving this so that I could get the truck back on the road, but after completing all the rust repairs on the roof I couldn't bring myself to leave the floor with this mess, so I started poking at it. It appears that they slapped this bondo/fiberglass mix on top of the dirty and rusty floor with no preparation, so it was just a crusty mess. The first picture below is about a fourth of the slabs of fiberglass that popped off. Once the loose stuff came up, I used a side grinder with a wire brush cup to remove the rest. It was a dirty, itchy mess. The second and third pictures show the rust on the driver side floor and the huge hole where the gas pedal was mounted in some of the fiberglass. The fourth and fifth picture show the passenger side floor and the top of the passenger side rocker panel. The cab appears to have a thin layer of undercoating on the bottom, and because both the roof and windshield leaked, it appears that the cab floor rusted from the top down (or inside to out). The good news is that the “A” pillar structure appears intact and the rocker panels are solid except on the top. I plan to fabricate the patch panels for repairing the floor. I bought a Harbor Freight bench top 30” metal brake for about $50 and a Harbor Freight 2 inch tear-drop mallet for about $8 for doing this. I already have some body hammers and dollys. I plan to use some of the leftover inner roof panel material (from the Craigslist roof that I bought for roof parts) to form some of the patch panels (it appears to be the same gauge as the floor). I also bought some 18 ga and 20 ga sheet metal drops at a local metal supply shop which sells drops by the pound. |

Re: Wampus Cat
Floor Rust 2
These are some in-progress shots. My brother is in town visiting his son and has been “enjoying” playing with the metal brake and pounding/fitting panels with me. Big thanks! The first picture is a panel being cut and formed for the passenger side floor. I don't have access to a metal roll former for making the stiffener channels for the floor, so my brother came up with the idea for cutting these parts from the leftover inner roof panel that already has some of these channel features. The second picture shows some of the repair panels tacked in place on the driver side floor. The third picture shows the formed piece that will be fitted to the top of the outer rocker panel on both sides of the cab. It had to be formed in two pieces because it was too long to fit in the metal brake, but we were able to create a pretty good reproduction of the flange where the door weatherstrip mounts. |

Re: Wampus Cat
Aggie91, ........ Thanks! I'm very happy with the shop electrical. It certainly beats dealing with the extension cords from the house, and occasional tripped breakers back at the main panel.

Re: Wampus Cat
Bed removal.
I removed the bed so that I could work on any rust issues on the back of the cab. The bed has a welded steel tread plate floor that I estimate adds 250 to 300 pounds to the weight of the bed, but I was still able to pull it with my engine hoist. I also built a dolly to store the bed out of the way and move it around the shop. The drivers side of the cab rear panel looks ok, but the passenger side may require a little surgical repair. Next, I'm going to pull the gas tank so that I can inspect this area from the inside also. .
