WHAT we’re doing, and HOW we’re doing it!

Rust beneath a lead-acid car battery is the most common rust you’ll find on an old car. It’s an easy fix for cars with a bolt-in shelf to hold the battery, and then it gets more difficult from there. Triumph had a somewhat removeable metal tray welded into the firewall of the TR2-TR3B cars, and replacements are readily available to facilitate the repair. But starting with the TR4, things became much more difficult. With the TR4-TR6 models, the battery “shelf” was part of the firewall assembly, with no factory seam to split and replace a section. Repair panels have also not been available, so we had to learn and perfect a method to repair this trouble spot ourselves. It all began with flat new sheet metal and drawing tools, and the pattern for the stiffening and drainage ribs are laid out. From here we move over to the bead roller and create the ribs as close to factory dimensions as possible. True, it will never be seen with a battery sitting on top (and hopefully a plastic battery tray as well), but remember that the primary reason Triumph added these ribs was to strengthen the area, and provide several drainage pathways. They really do need to be in there! Stop back next week and we’ll show you the completed panel, positioned and tacked into the firewall, ready for final welding.

If you’ve never driven a TR with overdrive, you don’t know what you’re missing. And once you have a properly functioning overdrive in your TR, you’ll never have another without it! Whenever I acquire a new TR for my collection, if it doesn’t have an overdrive you can bet that it’s the first thing I add. Now I know a lot of you will say “I never take my Triumph out on the highway”, or something similar, but I’ll also tell you that neither do I unless it’s for a very short time and unavoidable. You see, an overdrive isn’t just about cruising along at 70+ MPH and lowering the strain on the engine and the noise levels inside. For that, a 5-speed conversion would work but the gear ratio spacing isn’t optimal for the Triumph power curves. With an overdrive, you pick up either 2 or 3 extra gears (depending on A or J type o/d) and believe me there are times when I use them all! The cost of a 5-speed conversion or an overdrive conversion is about the same, so why not opt for the original spec and keep the correct gear ratios? If your car does not currently have an overdrive, we’re able to source factory rebuilt units and perform the conversion here. And if you have overdrive and it isn’t working correctly, we can repair and rebuild them to enhance your Triumph driving pleasure.

Following along with the test-fitting subject from last week, here is another example from the same TR3B, although taken prior to last week’s photo. Many of the TR2-TR3B cars we see here or at shows have dash rail and door top cappings that don’t align or touch or rub, looking bad or damaging the leather or vinyl covering. Test fitting now guarantees that all components line-up correctly, and if you have a situation like this it’s O.K. to trim away some of the base capping material, and be sure to add extra clearance for today’s thicker leather and vinyl. So why don’t these original parts fit better? Perhaps they didn’t fit well when new, but in this case we know that this owner also had a parts car. There’s no telling where these parts might have come from, but back when the wrecking yards were well supplied with derelict sidescreen TR’s, it wouldn’t have been unusual to pull a “nicer” capping from a junk yard car to replace a worn or damaged part on your own TR3 (as long as the color matched). In most cases, when test fitting the cappings, it’s not unusual to work on them for several hours, removing twists and dents, or re-welding loose button caps on the TR3A-TR3B door tops. Only after all 8 pieces have been repaired, fitted, and adjusted will we come anywhere near them with the vinyl, leather, and glue!

To achieve the fit and finish that is expected today of a quality restoration, just about every piece must be test fit and adjusted multiple times. True, today’s highest quality restorations are much nicer than what rolled off of the asembly line 50-60-70 years ago, but it’s hard to judge which flaws might have been original and which are due to poor workmanship of the restorer. So, the highest level of fit and finish is what’s generally expected today, especially if it’s a TR that was restored here at Macy’s Garage! Take the relatively simple task of installing the glove box door. Most of the upholstered wood panels have deteriorated to the point where they need to be replaced. The replacements we make are exact duplicates of the originals (of which we have several samples), but look at the hole for the glove box lock. Had we simply pulled a new wood piece from our stock and covered it in vinyl before trying to fit it to the car, we’d have had a new problem to resolve. Test fitting early and often saves trouble later when it’s more difficult to adjust. So why didn’t the wood piece fit? It boils down to today’s vinyl being thicker than what Triumph used originally. This shrinks the size of the opening (and increases the size of the door facing), moving the door around where it shouldn’t be. A belt sander now made this a simple fix.

Welcome back following our January break! Mission accomplished and fingers crossed, it looks like we successfully split our web editing software into two smaller files without crashing it. We’ve also been busy creating new Triumph parts that are not available elsewhere. The two brackets shown in this week’s photo are front turn signal lamp brackets for late 1974-1976 TR6. We have a car here that was missing these brackets (both sides!), and none were to be had anywhere. Even used brackets seem unobtainable, so we had to roll up our sleeves (again) and make them here. Borrowing one from another car in the shop, we were able to create a CAD file and then print them on one of our three 3-D printers. Yes they are now plastic where as the originals were steel, but even plastic is better than the wonky strap brackets that were previously used on the car in question. We chose a reinforced High Temperature filament to create these brackets, so there is no need to anticipate a shortened life expectancy from not using metal. With the engineering and production solved, we are now able to offer these brackets in our eBay store for all late TR6 owners who might also need one (or a pair).
