Way back in November of 2011, I wrote about the machinery we were purchasing as a way to increase efficiency and quality as the cabinetry side of our business grew. If you would like to read about the first wave of machinery purchases, click HERE.
Within a few months of purchasing the machine chronicled in the previous blog entry, a Grizzly sliding table saw, I was back at it again. The reason we seem to have gone on a machine purchasing spree is directly related to our small company’s story: consistent growth over the past 2.5 years. You can read more about that HERE. This was never an issue of machine envy or unwarranted desire. All “new” machinery must either either increase the efficiency or the quality of the process being performed, preferably both.
A third factor must also be considered, and that is the cost of the machine in question. Just because a new machine can do the job better and faster, does not mean one should immediately go out and buy it. The value of the machine must be taken into consideration. Notice that I said value and not price. If you purchase an inexpensive machine, simply because you are unwilling to spend much money, you may be causing yourself more headaches and stress by using a machine that is past it prime. On the flip side, if you decide to only purchase the newest and the “best” machinery, you may tax your cash flow so much that it threatens the livelihood of your business. Each machine purchased is an investment in the business, not a personal toy. When you treat each machine as such, the sticker price becomes less of a factor, and the utilitarian value of the machine takes center stage.
Yet another factor that must be considered by any business owner when purchasing machinery is the question of “who will be using this machine?” When I was a one man operation, I was able to use older machinery that took more finessing to achieve good results, and I was able to use shop-made jigs with pretty good results. Fast forward to when I had one, then two, and now three employees fabricating products for my company. The story has changed significantly. Just because I could overcome the obstacles and limitations of a machine to achieve good results, does not mean my employees could or should have to. One of your job as a boss is to make the process of completing the task assigned as simple and repeatable as possible. We are always analyzing whether or not a certain process is being completed as simply and as efficiently as possible, and when necessary, we look into purchasing a machine that will solve some of our limitations.
Now, on to the machinery!
Air Assisted Airless Sprayer – 8/11
Shortly after purchasing the sliding table saw, the next area of production that we realized we needed to address was our finishing process. We finish all of the furniture, cabinetry, and shutters that we manufacture. Prior to manufacturing furniture and cabinetry, we finished our interior shutters using pressure pots to spray oil based paints and lacquer. But once we began fabricating and finishing cabinets and furniture, we learned that a pressure pot was not the best way to spray sanding sealer, lacquer, or varnish. The pressure pots just created to much overspray, resulting in a rough finish on large flat surfaces, such as a table top, or when spraying the inside of a cabinet. The quality of our painted and lacquer finishes was not to our liking, so we began investigating our options.
We met with our finishing rep and decided to spend $2000 on a new Binks air-assisted airless spray system, complete with the pump, hoses, and gun. The overspray is pretty much non-existent and the volume of material that is applied to the surface is greatly increased over the pressure pots.
The resulting finish achieved using the air-assisted airless is incredible! Perfectly smooth surfaces on large dining tables and inside of bookcases. We also switched over to using tinted lacquers to paint all of our furniture and cabinetry. We still use pressure pots to apply the oil based paints to our shutters, and to apply stain to all of our products, but when it comes to spraying sealers, lacquers, and varnishes, we go with the air-assisted airless.
JLT Door Clamp – 2/12
After purchasing the air-assisted airless, our sabbatical from purchasing new machinery came to an end when the owner of a local cabinet shop, who had done some edgebanding for us, called to see if I was interested in a few machines he wanted to part with. The JLT door clamp, seen above, and the Busellato UniBohr machine, seen below, were taking up space and collecting dust, and he wanted them gone. He said they could be mine, along with an air-assisted airless pump, for $1800. It didn’t take much convincing for me to jump at the opportunity, since I had almost purchased the UniBohr machine the previous year from him for $1800. For the same price I was getting two more machines!
Let’s first look at the JLT door clamp. Prior to this machine, we were building all of our doors using parallel bar clamps, which get the job done, but makes the process of building doors tedious and inaccurate. Building perfectly square doors was tricky and elusive. I don’t know if I was unwilling to spend the money, or if I was just unaware of the ease and accuracy this machines lends to building doors, but until this offer, I had no plans to purchase a door clamp machine. If you build your own doors, this is the next machine you need to purchase! The quality of our doors is infinitely improved. Every door is square, all the seams between the rails and stiles are tight and secure, and the door is clamped up tight in about 5 seconds!
Busellato UniBohr Machine – 2/12
The other machine we acquired from that group purchase was this Unibohr drilling machine. As detailed in the previous machine blog entry, we were drilling all of our system holes using a Blum MiniDrill, so we planned on using this machine to drill all the drawer parts. This machine can bore horizontally into the end of the fronts and backs, as seen in the picture, and with the flip of two switches, the entire head swivels 180 degrees and the drill bits bore perpendicular into the sides.
Before we purchased this machine, fabricating drawer boxes was little more than a nightmare. We were using a shop-made jig and a collared drill bit to manually bore our drawer parts. As you can imagine, accuracy was not its strong point. As with so many shop built jigs, the more we used it, the further out of alignment and the looser its tolerances became. Eventually, it was not worth it anymore and we relegated it to some dusty corner of the shop.
Next, I attempt to solve this issue with a machine we already owned. We use a 97 head Marcon drill machine to bore the holes in the stiles of our shutters, but the drilling depth and fence settings could not be touched. So, I designed and fabricated some jigs and all was well, until we ran into the same problem as before: the tolerances and alignment were compromised little by little by normal wear and tear. Thankfully, about this time is when we purchased the Unibohr, so after a few hours of adjustment and fine tuning, we had beautifully bored drawer parts.
We will pick up this story next time with plenty more new equipment.
