Shop Tip of the month
Mill Indicator Holder/Steven Lang
This indicator holder was made by cutting the dovetail off a P/N 1290 Steady Rest Riser. The parts can also be made from scratch.
GM engineer and long time Sherline user Steven Lang sent in an example of this useful indicator holder he had made from a P/N 1290 Steady Rest Riser Block ($50.00). By machining down the thickness and drilling an additional hole to mount the indicator, he was able to turn it in to a Z-axis holder for an inexpensive dial indicator. The extrusions of the 1290 come 1.2" thick, but Steven machined his down to a thickness of 0.50" to take up less vertical space. (If you were to saw one in half you can make two holders.) The 10-32 hole to mount the indicator is based on the location of the flange on this particular indicator. Check the one you are using and modify the hole location if needed. Although you could use a standard 10-32 socket head cap screw to secure the holder to the column dovetail, Steven has also turned a nice looking knurled knob and pressed it onto the head of 10-32 screw to eliminate the need for a hex key when moving the holder to a different position.
Note also that without the indicator mounted, a part like this could be easily adapted for use as a positionable hard stop on the lathe or mill.

If you click on the link below and read the full tip, Steven also offers a way to make the mount work where space is limited by making one additional piece that allows the indicator to be mounted above the headstock.

New Product Spotlight
Sherline Short 90∞ Angle Plate, P/N 3561 ($60.00)
At only 4" long, the P/N 3561 90∞ Angle Plate is short enough to be used in line with or perpendicular to the mill table.
This angle plate is a very useful work-holding fixture for milling. It is 3-1/2" long as opposed to the P/N 3559 90∞ angle plate which is 10" long. Sherlineís lead toolmaker, Pam Weiss came up with this part initially to use up cut-offs at the end of the extrusions used for the longer angle plates and also to solve some particular set-up problems. With two perpendicular surfaces, parts can also be held from two directions at once. It can be used to hold parts on either the vertical or horizontal surface, but its short length gives it the additional advantage of being able to be oriented either parallel to or perpendicular to the mill table, giving you some extra setup options when working on small parts. It has two T-slots running full length on each face. It is made from extruded aluminum with accurately machined faces and a black anodized finish. Provided with the plate are four 10-32 x 3/8" mounting screws and T-nuts.
This fixture is not limited to use on Sherline tools. Like the rotary table and some other Sherline accessories, it could be useful on larger machines in your shop as well.
