« Part 2: Update on Cleaning Part 3 of Invicta/Delta DJ-15 Restoration series Part 4: Reassembly »

It’s been a while since I’ve been able to provide an update on the status of my jointer restoration (I think this is actually more of a refurbishment, as additional research that I’ve done here on LJ’s and other woodworking forums has educated me further regarding the extreme lengths to which others have gone in order to bring equipment back to life…the state of this particular jointer doesn’t look so bad compared to others I’ve seen). My wife and I welcomed our first-born child into our lives recently, and well, as they say, life will never be the same and the rest is history. Needless to say, many sleepless nights do not bode well for allowing for sufficient time to be spent in the garage…or anything else for that matter. Now that we’ve got some time under our belts, we’ve worked out a good (or good enough) system such that I’ve found bits of time here and there to spend in the garage getting back to this project. But I digress…

In my previous entry for this blog series, I had all of the jointer components cleaned up, taped off to protect any machined surfaces (as needed), and primed. So, the next logical step was to paint. I should preface all of this with, looking back at the post clean-up photos, I probably could have saved myself a lot of time (and a little bit of money) by simply putting the jointer back together without painting. As shown in my previous blog entry, a little Simple Green goes a long way to sprucing things up. But, I’m stubborn, enjoy a challenge, and figured that I had come so far as to completely tear down the darn thing, I might as well go all out. So, I purchased a low-end plug-n-play HVLP sprayer from HD and went to work. I should mention that I toyed with the idea of investing in a more robust system (i.e. compressor and stand-along HVLP gun/components), but I decided against that mainly because I didn’t want to make such a significant investment without knowing whether or not I would get enough use out of it. For example, a decent 20-30 gallon compressor would probably run about $250-$300, and a decent HVLP gun with appropriate components would likely run $50-$100. Add in supplementary components like air hoses, filters, etc., and you’re looking at $400-$500. Not that such an investment isn’t worth it, I just wasn’t sure at the time whether or not such an investment would be worth it for me. One could certainly make the argument that a compressor would certainly benefit me in future endeavors, and in hind-sight I probably should have gone that route for that reason alone. But, since this was my first attempt at spraying paint, I decided to go the route that I felt would provide reasonable results for minimal investment.

For those of you who have ever seen the show Dexter on Showtime, that’s pretty much what the one stall of my garage looked like for the better part of a month (I should also note that it was the stall portion of the garage where my car is usually parked…I’m sure you can figure out why). I constructed a make-shift paint booth out of painters plastic, which I taped to the garage ceiling and secured to construction lumber that rested on the garage floor (I put painters plastic down on the floor within the booth as well so as not to paint the actual floor. I’ve included a photograph below.

I took one of the front/back panels off of the cabinet stand to the local Sherwin Williams to have them mix up a matching paint color. I opted for SW All-Surface Acrylic Latex Enamel (High Gloss, Deep Base) in color “London Fog” (SW2106).

I set up all of the jointer components within the make-shift paint booth and went to work.

While the primary jointer components were drying, I closed off the paint booth entry with painters tape and set up the base cabinet and corresponding front/back panels outside of the booth for priming. I used some thin gauge wire to hang the panels from eye hooks installed in the ceiling for convenient access to both sides of the panels. Wondering what the red portion of the painters film is there near the bottom of the one side of the paint booth? Don’t worry, it’s not what you think. In an effort to be efficient, I intermittently painted the cutterhead guard with Rust-Oleum Proffesional High Performance Enamel Safety Red spray paint in between painting/drying sessions.

Once the primary jointer components were painted, I moved them out of the paint booth and moved the base cabinet components into the paint booth for painting. Again, I hung the front/back cabinet panels from the ceiling for convenience and easy access.

I’ve included a few photos below of the painted jointer components.

Note that the top-most photo above shows the majority of the fence components on the right-hand side. I’ve broken down most of the carriage/swivel components for cleaning, and I’ve cleaned up the face of the fence with some WD-40 and Scotch-Brite pad. I still need to prime/paint the carriage and back of the fence, but I’ll plan to do that with some spray primer/paint. Also note that in the bottom-most photo, I plugged the larger holes with a few of those disposable foam earplugs, so as not to get paint on the machined surfaces. I also chose to leave a single set screw in each of the threaded holes that typically contain a pair of set screws (I’m highlighting the fact that it is in fact 2 set screws per hole…took me a while to figure this out) for securing the eccentric bushings. I’m planning to replace the original set screws anyways, this way it kept paint off of the threads.

I’ve also been able to clean up, prime, and paint the sub-base assembly. As you can see in the photo below, the sub-base was heavily rusted/marked/scuffed, and just needed a little TLC.

After hitting it first with some Simple Green and a Scotch-Brite, followed by a wire wheel attachment on my power drill, all mixed together with lots of elbow grease, this is what it cleaned up to look like:

Then I hit it with a couple coats of Rust-Oleum Stops Rust Clean Metal Spray Primer, followed by 3 coats of Rust-Oleum Automotive Enamel Gloss Black Spray Paint:

Well, I think that covers it for now. I’ve begun reassembly of the main body of the jointer already. So far I’ve got all of the eccentric bushings installed, along with the corresponding four sets of pivot brackets, mounting plates (there’s actually 8 of these, 2 per pivot bracket), shafts, and adjustment levers/handles (only 2 of these, 1 for the infeed table, 1 for the outfeed table), all of which work together to control infeed/outfeed table adjustment.

One thing that I remembered during reassembly is that, some time ago, I remembered reading about issues with dust collection on this particular jointer, along with it’s bigger brother the 8-inch DJ-20. I remembered reading that some folks had machines where the chip deflector (mounted beneath the infeed table lip) and/or chipbreaker (mounted beneath the outfeed table lip) were designed/installed incorrectly. Looking at the exploded assembly drawings for the DJ-15, my guess is that the chipbreaker may be the culprit. I recently posted about this issue here. If anyone has any input/guidance/suggestions, it would be greatly appreciated.

Until next time…

Stellar job on the refurbishing of the DJ 15….It’s coming along nicely, and you’re doing a great job…And yes I watched every episode of Dexter….It does look like the set up Dexter used to kill off his victims…..!!

Congratulations on the newborn. When they become teenagers you will probably look back on this time with longing. Looks like you are doing a great job on this jointer restoration. Your temporary spray booth looks good too. Do you have any ventilation with it? Just curious as I am looking for a good spray booth solution.

Mike – Thanks so much for the congrats! It’s definitely a trying time, but being the youngest of three with two older sisters (I forgot to mention that our own new addition is a girl), I certainly won’t wish this time by!

I did not use any ventilation in my make-shift spray booth. When I first got started, I really didn’t do a whole lot of research into what should/not be done to maximize the efficiency and quality of the resulting paint job. As I got through my first couple painting sessions, I did a little bit of research, talked with a buddy of mine (who has a fair amount of experience with automotive restoration), and concluded that ventilation would have been a good thing, at the very least to help maximize the quality of the paint job given the set-up I had to work with and the lower-grade equipment I was using (not to mention my lack of experience). Admittedly, laziness got the better of me.

If I was going to make a habit of this restoration/refurbishment thing (which I may, who knows, we’ll see), I would definitely add some ventilation. At a minimum, I would use a box fan to provide air flow out of the paint booth. I would adhere a couple of standard HVAC filters to the box fan from inside the paint booth in order to protect the fan from any paint/dust/particle contaminants. This would, at a minimum, help with air flow within the paint booth in order to minimize any overspray. With my specific set-up, I would place the box fan on the side of the paint booth that faces the garage door to help direct the exhaust out of the garage. I have no experience whatsoever with this, but I think this makes sense. See the below photograph with mark-up for an example of what I’m talking about:

If you wanted to get even more fancy, you could add another box fan on the opposite side of the paint booth that acts as an intake and works with the outtake fan to provide cross ventilation/circulation. If I was smarter, I would have moved, or at least extended, my paint booth to the right in the above photo, as I have a small window on that wall that I could have opened to provide some fresh air intake. And, if I were to make a habit of this, I would make something a bit more permanent to a) minimize waste, and b) help maximize my time in the actual paint booth and not setting up to paint. There are plenty of examples around the internet where people have made make-shift garage paint booths using PVC pipe, fold-down walls, or just plain old stand-up/knock-down open-sided walls for a quick spray…all of which have a common theme in mind—ventilation Ventilation VENTILATION. In an ideal world you’d have a downdraft booth that provides clean air from above and vents contaminated air from below, just like they use in the automotive industry. For most of us hobbiest woodworkers, that’s just not an option.

I will say that I did follow a few steps to try and minimize contamination within my paint booth, as follows:

1. Before I constructed the paint booth, I gave the garage a fairly careful cleaning that included a) sweeping the floor, b) leaf-blowing the entire garage to stir up any lingering dust/particle build-up, and c) running my air cleaner for several hours to try and pick-up any dust stirred up in the process. This seemed to work fairly well.

2. Once the garage was clean, I was careful to lay painters plastic on the floor first, such that all of the seams created by the make-shift walls would fall on that plastic and not on the bare garage floor. That way I wasn’t pulling in outside dust from the garage floor that might be leftover from the cleaning process.

3. I created a sealable entry. Admittedly, by sealable I mean that I used painters tape…there are certainly more elegant solutions to this problem. But, my main point is that the only time the paint booth was open was when I was walking into or out of the booth. During painting and when I wasn’t painting, the booth was sealed up with tape. This helped to minimize any airborn dust/particles that inevitably get stirred up just from moving in/around the garage (not to mention the fact that the garage door was open for lighting purposes), and helped to prevent them from finding their way into the booth and eventually settling on wet/curing paint.

My set-up certainly wasn’t perfect, far from it actually. But, in the end, it actually worked out rather well. Having been through it once already, I would certainly make some changes as outlined above, all of which would require minimal effort and investment. I hope this helps…best of luck!
