Thank you for purchasing the Quill Stop for the Little Machine Shop 5550 and all Sieg SX2.7 compatible mills. Your feedback is always appreciated. Please email questions and comments to ******************.What’s Included1.Stop plate2.Quill bracket3.Button nut4.Threaded rod, 1/2-20 x 6"5.Parts Baga.Socket cap screw, 3-.5 x 20mm (2)b.Socket cap screw, 3-.5 x 10mm (2)c.Socket set screw, 10-24 x 1/4"d.Washer, 5mm (2)e.Washer, 3mm (2)Tools Required1.Hex keys: 3/32”,2.5mm, #1 Phillips screwdriver, 8mm wrench, smallsquareInstallation1.Remove power to the mill and remove tooling from the spindle.2.Remove the screws and display bracket that secure the depth gage tothe quill.3.Remove the t-block head stud from the display bracket.4.Lower the bottom of the height gage tongue below the bottom of thequill to access the 2 holes in the height gage tongue from the back with a#1 Phillips screwdriver.5.Feed the 3mm Phillips screws just removed through the back of theheight gage tongue and mount the t-block head to the front of theheight gage.6.Push the height gage tongue up and out of the way of the quill. Lowerthe quill a few inches and lock in place to make mounting the quillbracket easier to mount.7.Place the display bracket in front of the quill bracket and align themounting holes. Mount the display and quill brackets to the quill asshown using the 2 supplied 3 x 20mm socket cap screws. Use a smallsquare to align the quill bracket perpendicular to the edge of the faceplate on the mill head as shown. When aligned, tighten the 3mm socketcap screws securely to the quill, but, of course, do not over tighten. It isrecommended to use a standard-end (not ball-end) 2.5mm hex l-keywhen tightening the 3mm screws.8.Release the quill and raise to its top position. While doing this, placeone of the supplied 3mm large format washers on the display bracket sothat the washer slides up onto the t-block.9.Slide the t-block down onto the display bracket. Secure the t-block tothe display bracket using a 3mm large format washer and nut removedearlier. Tighten the nut with an 8mm wrench.10.Remove the lower 2, 3mm screws from the cover plate of the mill head.Mount the stop plate using the supplied 3 x 10mm socket cap screwsusing these holes. Align the stop plate to be perpendicular to the millhead cover plate using a small square. Tighten the screws.11.Feed the threaded rod down through the stop plate and screw the endwith the flat into the hole in the quill bracket leaving one or two threadsof the flat showing above the surface of the Plate. Position the flatoutward so that it will face the 10-24 x 1/4” set screw. Install andtighten the 10-24 set screw.12.Slide the button nut down over the 1/2-20 threaded rod to any spot above the stop plate and check theoperation of the Quill Stop by rotating the quill until the Button Nut contacts the plate.13.Important: when operating the Quill Stop, lower the quill until thebutton nut meets the top of the stop plate and do not force furtherdownward movement. The handles of the quill present a high-leverageforce which may overcome the shear strength of the 3mm socket capscrews holding the stop plate in place.14.To ensure smooth operation, minor adjustments may be made to thehorizontal position of the stop plate and quill plate slightly in eitherdirection. Loosen the fasteners, adjust, and re-tighten the fasteners toconfirm a smooth operation. Congratulations, installation of your newQuill Stop is complete!OperationThe Quill Stop is simple to operate, simply press the button and the nutdisengages from the thread. Slide to the desired position and release thebutton to engage the threads. Turning the nut then allows for precisionmicro-adjustments of depth of cut.The Quill Stop is great for doing chamfers. With the spindle stopped and thechamfer tool in the spindle and centered on the hole, lower the quill until thechamfer tool seats in the hole. Then lower the Button Nut until it contactsthe Stop Block. Rotate the Button Nut clockwise a half-turn to back out ofthe hole a bit and release the quill. Lower the spindle using the quill to makesure that the chamfer tool is not contacting the part. Start the spindleturning (150 RPM is recommended for chamfers) and lower the spindle usingthe quill. Then start a cycle of rotating the Button Nut counter clockwise insmall increments while checking the depth of the chamfer by lowering andraising the quill. This is a great way to sneak-up on the correct chamfer depth.。
