1976 Morgan 4/4 Roadster

Posted on July 8, 2023July 8, 2023 by Auto Resto in Automotive Restoration, Bespoke Fabrication, Restoration, Rust Repairs

When I began my traineeship as an artisan coach builder, I had the privilege of working on classic vehicles like the Morgan 4/4 Roadster.

Morgan – body & Panel repairs

One of the first steps in the repair process involved squaring and securing the timber body frame to the chassis. Then, the body panels were fitted to ensure proper alignment and functionality.

The vehicle was initially delivered without any attached parts, exposing the timber frame.

We fitted the rear quarter panel to determine the extent of the sill panel and the position of the rebate joint.

Before commencement of repairs, we also trial fitted the lower section of the front cowl panel. Subsequently, we fabricated the sill panel section and integrated it with the front cowl panel.

To ensure a seamless integration, we notched the timber body frame to allow for the smooth connection of the quarter panel and sill panel section.

The quarter panel section was stepped to create a rebate that would overlap with the cowl panel (sill panel section) and provide a flush finish.

The finished joint between the cowl panel and the quarter panel (sill panel sections), as originally manufactured by Morgan.

We repeated the process by notching the timber body frame at the dovetail end to ensure the smooth integration of the quarter panel and dovetail panel.

The rear section of the quarter panel section was also stepped to create a rebate for the dovetail panel, resulting in a flush joint between the two sections.

The finished joint between the dovetail section and the quarter panel.

Morgan – panel alignment

Once the repairs were complete, we performed a post fitment and alignment of the body panels on the Morgan. This step was crucial before proceeding with painting as it ensured uniform separation between the panels, eliminating the risk of binding or scuffing with adjacent panel sections.

Before fitting and aligning the reproduction quarter panels, we made necessary alterations to the timber frame.

During the fitting of the front panels, we tweaked and laser-leveled the chassis to achieve improved gaps and alignment.

We carefully fitted and adjusted the fenders to ensure a consistent gap between adjacent panels.

The rear quarter panels were installed along with the doors, and their contour was manipulated to create a uniform seal.

We also manipulated the rear dovetail panel to fit the new timber frame.

The final result was a well-finished vehicle body with uniform gaps, achieved without forcing the parts into position.

Morgan – Repair Panels

Fortunately, for this particular vehicle, we had a limited number of repair panels to fabricate as the owner provided aftermarket quarter panels.

The new sill panel sections fabricated in house.

Front valance panel was fabricated in house with a stainless steel wired edge.

Fortunately the customer was able to source the new fabricated quarter panels from the UK.

Morgan – Bespoke Panel Fabrication

When the vehicle initially came to us, it was missing two important panel sections—the front and rear valance panels. Upon its return, after having the mechanical items reinstalled, we fabricated and installed a bespoke center console.

The Morgan did not have a front valance panel originally, but the owner wanted to add front lights without compromising the aesthetic. To achieve this, we replicated the design of the rear and fabricated a custom front valance panel.

For the rear valance panel, we used 1mm steel plate and reinforced the edge with wire encasement.

Designing the center console was a meticulous task, considering the limited space available for the seats and the operation of the pedal assembly. We carefully crafted a center console that met these precise requirements.

Toyota HZJ75 Landcruiser

Posted on July 4, 2023July 4, 2023 by Auto Resto in Front Windscreen, Rust Repairs, Toyota HZJ75 Landcruiser

Despite Toyota’s efforts to improve their past models, the relentless corrosion continues to wreak havoc on these seemingly indestructible vehicles. This particular vehicle has endured a tough life, and the signs of neglect are unmistakable. At Auto Resto, we rarely decline projects, so we gladly accepted this challenge.

At Auto Resto, we accept the challenges that others decline.

Turret aperture

The corrosion damage around the front windscreen aperture was so severe that we needed to fabricate an entire new turret centre section and each of the turret corners to complete the repair.

Additionally, the internal turret reinforcement section was replaced.

Our highly skilled artisans crafted all the panels shown here in-house.

Bulkhead Aperture

The corrosion damage to the bulkhead section was further complicated by the extensive corrosion found in the A-Pillar sections, the bulkhead reinforcement, and behind the dash panel instruments.

To ensure safety during the repairs, the cabin interior and dash panel instruments were removed to eliminate the potential risk of fire.

The fabricated panel sections illustrated here were just the beginning, as further repairs were still required.

LHS Turret frame

While repairing the left-hand side (LHS) turret corner, it was discovered that the frame had been weakened by corrosion.

The turret frame, which is integral to the door frame aperture, had to be repaired with a new section. The turret frame, which plays a crucial role in the door frame aperture, required repair. A new section was fabricated to replace the damaged portion which was subsequently cut out and replaced.

The repair of the frame’s top corner was successfully completed before proceeding with fabrication of the drip rail panel.

Pillar Drip rail

During the repair of the LHS turret corner and frame, it was necessary to remove the drip rail (gutter) section. It was discovered that the drip rail had suffered extensive corrosion along its entire length, resulting in weakened structural integrity.

To address this issue, a new drip rail panel section was fabricated and carefully shaped to fit the vehicle.

A-Pillar Section

The lower section of the A-pillars displayed visible corrosion damage, which is typically caused by water ingress originating from the turret section.

The A-pillar is made up of overlapping panel sections, which forms to provide the overall structural strength and rigidity of the vehicle.

LHS A-Pillar – External Corrosion Damage

cleaning process

At Auto Resto, every repair is performed with great attention to detail, and one crucial aspect is ensuring that the surface is thoroughly prepared and cleaned to eliminate any corrosion contaminants.

To achieve a high-quality finish that meets the Australian Standards AS 1627.4—2005 for metal finishing and surface pre-treatment, we employ a combination of processes and techniques. These methods ensure that the repaired surface meets the required standards for durability.

Our approach also includes multi-staged pre and post coating treatments.

Panel fabrication

At Auto Resto, metal fabrication is a crucial part of most projects. Finding ready-made replacement panel sections, even for modern vehicles, is often challenging.

Even if a portion can be sourced from a donor vehicle, it usually requires minor repairs to ensure a proper fit and finish.

By fabricating these sections in-house, we can ensure the highest quality and durability of the repairs. Our skilled artisans meticulously work with new metal to fabricate the necessary panel sections, allowing us to confidently stand behind our warranty for corrosion repairs.

Metal Restoration

There is nothing more satisfying than the result of a metal finished repair.

Prior to the final welding of the metal sections, it is essential to properly fit the panels along with the associated parts.

This is a common repair at our workshop and we also produce custom-made replacement panel sections that are made to order.

Holden HQ Sedan

Posted on November 5, 2019July 6, 2023 by Auto Resto in Rust Repairs

Introduction

After serving faithfully for forty-six years, the Holden HQ Sedan, a symbol of automotive heritage, faced significant deterioration due to corrosion. This article delves into the consultation process at Auto Resto, assessment of the corrosion issues, and the tailored proposal to address the concerns presented to the prospective client.

Furthermore, it explores the risks posed and the unintended consequences of substandard repairs. Discover how Auto Resto’s process focuses on identifying the root cause and rebuilding the vehicle’s structure from the inside out.

In the case of this Holden HQ Sedan, consulting with our in-house experts who specialize in classic car restoration is essential. Auto Resto possess the knowledge and experience to evaluate the severity of corrosion issues in the vehicle. By leveraging on our expertise, you can gain valuable insights into the extent of the corrosion damage and make informed decisions about the necessary repairs.

The first step of the process is recognising the visible signs of deterioration and telltale indicators that may point to underlying corrosion issues. Rust spots and unsightly blemishes on the exterior, often serve as an early warning sign. Any paint bubbling, may also signal corrosion lurking beneath the surface.

The condition of the vehicle is assessed and a visual inspection performed to identify visible signs of corrosion damage. The potential risks and safety concerns associated with compromised structure are also noted.

For this Holden HQ Sedan, we identified critical areas like the cowl, A-pillars, floor pans, door hinges, and front windscreen prone to corrosion.

Although unknown to us at this stage, this section of the vehicle had been repaired (by others) on two separate occasions. The substandard repairs (presumably cost efficient), had compounded the problem, driving the corrosion deeper into the vehicle structure and inadvertently increasing our scope of work.

Our process involved exploring the root cause of the corrosion issues and restoring the structure by rebuilding it from the inside out.

RHS Front Windscreen Aperture

The photo below shows the condition of the right-hand side (RHS) of the dash after removing the front windscreen, revealing the extent of the deterioration.

Over time, moisture trapped by silicon sealer and cosmetic repairs has penetrated into the metal structure of the dash panel. The damage is extensive, affecting not only the RHS windscreen pillar (aperture) but also the stainless steel windscreen trim fasteners.

The corrosion damage was so advanced that it has even reached the upper areas of the plenum chamber and A-Pillar structure. Which was not initially apparent was that the lower reaches of the plenum chamber have also been affected.

RHS Cowl Panel

In the photo below, the owner-provided RHS replacement cowl panel is being fitted to the vehicle. While aligning the panel with the RHS door and fender, significant alterations were necessary to ensure proper alignment of the stainless steel windscreen trim.

Following removing of the external cowl panel section, a substantial amount of debris and corrosion species were exposed. Clearing the debris revealed weakened and perforated panel sections caused by extensive corrosion.

This area forms the underlying structure of the cabin, consisting of multiple layers of overlapping panels. It serves as the juncture point for the RHS A-Pillar, plenum chamber, dash panel, and windscreen cowl panel.

RHS Windscreen Pillar / Door Aperture Section

At first glance, this section appeared relatively solid, but closer inspection revealed hidden issues.

In addition to the obvious missing lower section, a previous repairer had bronze-welded a patch on top and filled the void with plastic filler. Originally, this section consists of two layers (upper and lower sections) that form the structure.

Internal Cowl Panel Duct (plenum chamber)

While removing the Internal Cowl Duct, we noticed corrosion embedded in the seal on the underside of the plenum chamber. The area where the cowl duct is fixed is shown in the photograph below. Accessing and repairing this area behind the dash was a challenge.

The only reliable solution to address this issue was to remove the entire external cowl panel, providing access to the plenum chamber. If left unrepaired, water ingress into the vehicle cabin could eventually lead to rusting of the floor pans.

Internal Corrosion Issues

Despite the progress made, there was one more surprise in store for us. The vehicle still had unresolved internal corrosion issues, which required further attention. To see the full video of the work completed, check out the title “Rust Repairs-Holden HQ Sedan.”

LHR Fender – Repair

This video illustrates the repair process on the rear fender of a VW Beetle Convertible.

The cracks that were visible in the fender panel were the result of a failed attempt to repair a vertical fracture. The extent of the damage was assessed and a new replacement panel was fabricated to the size required. The damaged area was then cut out completely the new replacement panel was aligned and fully welded.

Rear C-Pillar Restoration

This Chevrolet BelAir had significant corrosion damage in both of the rear C-Pillar’s. The repair process involved the removal of interlocking panel sections which provide the structure. The surface was cleaned free of contaminants and etch primed. The sections removed were re-fabricated and the structure repaired from the inside out.

Holden EJ – Fender

Holden EJ – Fender
This fender belongs to an Holden EJ Ute.

Sometimes a clients budget needs to be staggered over time and we don’t always get to see the whole vehicle all at once.

This fender had some minor issues in the past which could have been repaired better by the other repairer. At first sight, the corrosion appeared to be concentrated at the lower rear section of the fender.

The fender was then sandblasted to remove the paint and corrosion contaminants.
After the blasting process, the fender was reassessed and we found that the upper rear section of the fender had a small concentration of corrosion perforations.

Rene created a pattern of the fender sections and then fabricated the complete external (rear section) and lower internal fenders sections.

The corroded internal & external fender sections were then cut out and the replicated panel sections were fuse welded in place.

This may seem to be an extreme approach, but at Auto Resto we warranty our rust repairs for 5 years. We are passionate about restoring vehicles and eliminating corrosion.
