unnecessary. Experienced scroll-sawyers generally consider the hold-downs a nuisance and remove them altogether. On the Excaliber, Hegner. and RBI 220VS. you can easily swing ihe hold-down out of the way w ithout having to remove ihe Made. On most saws, you need to remove the hold-down to achieve the full depth of cut specified by the saw manufacturer (see chart on page 73.) do this. In addition to a dust blower, the Hegner has a dust port attachment beneath the table, which you can connect to a vacuum. It flips down to access the Dust Blowers The dusi blowers on all the saws I tested work as advertised: they blow the sawdust away from ihe cut line so you can see what you're doing. Hegner has the cleanest arrangement: ihe blower nozzle is built into the upper arm. allow ing clear v ision of the blade. On the Delta, the nozzle is attached to a cumbersome hold-down/finger guard assembly. The plastic blower tubes on the RBI saws require a slight adjustment each time you reposition the hold down fool, in order to direct the air stream directly al the cut line. The metal blower tube attachment on the Shopsmilh is a complicated-looking affair, most likely designed to double as a finger guard. Unfortunately, the nozzle makes il difficult to install the upper blade clamp when changing blades. The metal blower lube on the Excaliber comes mounted on the top of the upper arm. To increase the blower's efficiency, you can easily reposition it on the bottom side of ihe arm and adjusi the blower lube slightly to direct the airflow. The blower produced enough wind, however, that I didn't find it necessarv to SOURCES - SlIK-.V - AMT Fourth Ave & Spring St. P.O.

The Final Analysis In ihis review, I've pointed out what to look lot in a quality stroll saw. and cited some examples ol which tools were better than others in each respecl. If you have a chance to iry oui any of ihe saws featured in this article, you may agree or disagree with mv observations. Alter all. we all have our own expectations of a tool, based on how we'll be using it. l or example, if 1 needed a scroll saw io finesse precise, intricate cuts m thin materials, the Hegner IXV would win. hands-dow n. The Delta, on ihe other hand, is a durable, fast-cutting workhorse, perfect for mass-producing dozens of cutouts in thick or large work pieces. Compared tu the Hegner. though, it's a bit too rough and aggressive for super-fine detail work. My favorite of the lot has lo be the Excaliber EX II because it's a smooth-running, precision machine with a good combination of features, not the least of which are its quick clamps. And. ihe Excaliber simply felt ihe most comfortable while cutting on it. The RBI saws didn't fare as well in my tests as the above three, bul they're still good enough lo be considered precision saws. Ami keep in mind lhal the main reason ihe RBI 220VS saw that i tested didn't measure up lo the lop performers was the tendency lo bum on thick stock when making light inside cuts, a situation thai should be eliminated with the redesign of ihe upper arm and the switch to a more rigid thrtisi bearing. The Shopsmilh was the most problematic of llie lot. bul it's also one of ihe least expensive. But don'i lake my word for it lest hop all ihe machines you're interested in. if you can. While doing so. lake the weight of the saw into consideration—if you want to haul il around lo craft shows, choose one that won't break your back.
