How to Testing a Jigsaw?
Cutting Fast: An obvious question when you compare different jigsaws‘ performance is “which saw pieces the fastest?” I produced a speed cutting test to identify the answer. Initially, I fitted each saw with a brand-new Bosch Progressor blade, developed particularly for quick, rough cutting. Using the aid of my spouse, Ann, I timed for how long it took as revealed in the lead photo on page 44, each saw to crosscut a 2×6. I took a number of passes, then balanced the times for each saw. I attempted to press each saw as difficult as I might without bogging its motor down.
Within the ultimate tally, the advanced-listed Festool kipped down the fastest regular period: 2.74 seconds, noteworthy since this saw does not possess the best-amperage motor or fastest edge swing speed within this group of jigsaws. the Makita clocked the next fastest cutting time — less than a tenth of a 2nd slower than the Festool. Publishing a slightly slower time than which was the Bosch, adopted (in timed order) from the Metabo, Milwaukee and Hitachi. The DeWALT used the rear of the pack up with a rather sluggish 4.27-minute average period.
The 2nd-and-a-half variation in between the fastest and slowest saws may not look like much. If you have lots of rafter ends to decoratively jigsaw, or perhaps a pile of curved parts to eliminate, however this time can truly accumulate.
Vibration: Regardless of how quick a jigsaw pieces, the less shake it creates, the much better. All jigsaws utilize some sort of counterbalance system to decrease the up-and-down shaking produced by blade and the reciprocating plunger, and some work much better than others.
In reality, I hired as it varied under different circumstances, it rather challenging to precisely evaluate the vibration of the various saws within the group. For instance, the DeWALT felt extremely smooth-running when idling at complete speed. Nevertheless, after I place the tool to timber, it made significantly more vibration.
After careful consideration, I hired the Bosch and Festool, carefully followed Makita and by the Milwaukee, regularly created minimal shake when reducing a number of timber types and thicknesses having a variety of blades. That isn’t to state the DeWALT and Hitachi create unacceptable amounts of vibration, however they simply didn’t feel as the top saws as smooth running. At the end of the pack, the Metabo jigsaw regularly made more vibration than the other saws.
Reducing easily: Getting clean jigsaw cuts with just lighting splintering, tearout and surface chipping is mainly a matter of choosing a blade that’s developed for the task. However I still wished to see simply how smooth a cut each saw can creating using a general purpose knife. I fit each observed having an excellent-toothed edge and set it to some medium speed using a slight orbit (# 1). I then took a number of cuts with each on the bit of 3/4″ melamine– a product well-known for chipping quickly.
I chose the cutoffs that showed the cleanest edge made by each saw, after try out different rates of feed. The Bosch, helped, I think, by its accuracy control manual, quit the clearest cut sides. With reductions just somewhat more rough than the Bosch were DeWALT, Festool and the Makita, followed by the other saws. It is worth keeping in mind that I had the ability to obtain a much cleaner cut with all these saws by installing them having a special saw blade developed for laminates, in addition to an anti-splinter insert.
Cutting precisely: The major factors that impact the precision of jigsaw cuts are: How you can easily see the line of cut and just how well the saw’s blade remains square towards the workpiece (or in a fixed angle throughout bevel cuts). Typically, a with less of its body overhanging the edge is simpler to utilize, particularly when you’re trying to follow a curvaceous line or working in cramped quarters, state when eliminating a scrollwork pattern. The Bosch and Metabo’s open front end configuration make it a lot easier for me to determine the blade without needing to crane my neck. The Milwaukee and Hitachi possess the most blade obscuring body overhangs, however the previous’s built-in LED light assists to enhance its line-of-cut visibility.
