APRIL SHOWERS… IN MAY
May 11, 2023 – With a stressful week—both in terms of the bus and in my personal life—I took Thursday off for a much-needed mental health/R&R day.
Mostly recharged, I was back at in on Friday. Reevaluating the two “deleted” windows, I was very unhappy with the results of the two (lower) window sections which I’d installed last Tuesday. In retrospect, I found the 3M Panel Bonding Adhesive to be difficult to work with and mostly ineffective (for a variety of reasons, mostly due to my technique). While the curb side seemed to adhere properly, the one on the driver’s side did not. As such, this panel was removed, with the residual adhesive cleaned off, and then reapplied; this time using Loctite PL Premium construction adhesive to join the surfaces as well as adding pop rivets around the perimeter. This adhesive was also used to bond the two sections together. While my intention was to do this on both sides, I did not have enough high-powered magnets to do so simultaneously and with this adhesive having a 24-hour cure time, I had to push out doing the curb side until tomorrow. Instead of this, I spent the rest of the day beginning to measure and cut patches to be used to cover the remaining miscellaneous holes in the body. With various pieces of leftover sheet metal, I was able to cut six of the seven of the patch panels needed; for the last, I will need to procure one more 24x24” sheet (along with more rivets needed to secure them).
With other obligations pending on Saturday, I did little more than re-adhere the second window’s lower panel (which again, was secured by rivets) and primer the first deleted window’s panels. Several weeks ago, when I was searching for a mobile welder to help with patching up the numerous holes in the bus’s body, I was aware of a nearby neighbor (Aaron) who was a welder, though during the process of my search, I was never able to get in touch with him. Later on Saturday, in an act of serendipity, I ran into and talked with him about the previous welders’ difficulties and he agreed to stop by the next afternoon to take a look at my project (that of welding/filling the holes in the lower, aluminum section of the coach.
On Sunday, Aaron came by to evaluate and—with his 25+ years of experience—knew almost immediately the issue (which in my case was that of these panels needing to be TIG welded on AC so that the material’s oxide later is broken apart). His assumption was that the previous welder was either not experienced enough to be aware of this or that his welding machine was not capable/suited to welding on AC. Confident that he could address this, he was to begin sourcing the needed material (sheet aluminum) for the project the following day. Assuming that this can/will be done, it will add significantly to my cost. Based on the original bid by welder #1, we had budgeted $800 in total for this welding and fabrication work. By the time he was “finished” (which still did not include closing off the seven holes in the aluminum), we’d already forked over $700. Between the needed additional material and Aaron’s $85/hour labor rate, we’ll end up easily exceeding our initial $800 budget. Even so, we’ll have the peace of mind in knowing that we did it right.
On a related note, as previously mentioned, I participate in the Facebook group, Shuttle Bus Conversions. This group consists of over 22,000 members which either have built, are building or are planning to purchase a shuttle bus for the purpose of RV conversion; needless to say, collectively, it’s been a wealth of valuable information. In a recent thread, one (experienced) member relayed to another (newbie) that, in terms of budgeting (either time and/or funds), one should calculate their best guess as to both the cost and time involved, and then double both. In our personal experiences this far, sadly, this has proven to be true.
So, at least for the time being, we are back in a holding pattern while we wait for Aaron to source material(s) and work us into his schedule. In the meantime, I need to reevaluate my to do list so as to be able to continue working on tasks which are in process (i.e., sealing windows) as well as possibly bringing some things forward from when they were planned, such as addressing roof penetrations (fans) and coating. This will also provide more time to consider how we might address the application of a “beauty” overlay on our new rear panel.
On Monday, the second “deleted” window’s patch panels received a coat of primer and theses along with the remaining windows were sealed with silicon lap sealant. Far from a perfect job, this was done quickly and thus, somewhat sloppily. These windows’ sealant will be stripped off again prior to and re-sealed after the exterior is repainted; with this being one of the last major items on the conversion’s checklist. As such, at this point, perfection is not what I was after, but rather a functional sealing so as to enable work on the interior to commence. Later in the day, I heard back from my neighbor, Aaron (welder #3). He was able so source a 4x8 sheet of aluminum (at $130), and quoted me at a discounted labor rate of $85/hour—estimating the job to take 6-8 hours. This part of the work—which was originally to have been included in welder #1’s bid at $800—will run an additional $650-$800, above the $700 already spent. Again, doubling what I’d originally planned to spend. Ugh! Aware that this had dragged on for some time, Aaron had indicated that he would be able to work this into his schedule later in this week—possibly as early as Thursday, and no later than Saturday. Thanks neighbor!
With some late-afternoon thunderstorms and light rain on Monday, I was a bit leery about applying the roof coating, as it required between two to six hours of dry cure time. Tuesday AM’s weather forecast, however, showed nothing of the sort and so I decided to press on with its’ application. The product we used (Henry Tropi-Cool 887) was applied with a roller, and start to finish took about an hour and a half, with only half of that taken up by the actual application; the remainder being for preparation and clean up (… Another possible example of how one might underestimate the time required for a project). On Wednesday, the roof got a second coat and just in time… Shortly after the full (6-hour) recommended cure time, we were hit with a massive thunderstorm followed by rain, which was expected to last through the night and throughout tomorrow (Thursday); dropping around 2” of rainfall. Where the high desert of southern Colorado typically receives only about 12” of precipitation per year, we’ve not gotten four inches in just the last two storms! Though this sets my planned work schedule back a bit, on the bright side, if I can bear the morning winds, this will be a great opportunity to evaluate how well the bus is currently sealed and identity areas that may need attention.
