Stem attachment - fixed or swivel style |
TMA4 swivel stem with Ø 1/4" shaft
Swiss quality and design: attaches to the dovetail portions of all your test indicators. The stem portion can then be attached to any number of fixtures and holders. The swivel holder, with a 15mm long stem, shown above, rotates freely (±30°) in all directions until tightened into the desired position. Fixed stems are similar but do not swivel. These are the best quality stems available. Please note, not all stem attachments look exactly as pictured above. Click on a linked order number to purchase online. |

Rectangular or cylindrical shank |
Works in conjunction with a clamp. Order the items separately from the list below. The clamp attaches to any dovetail. The rectangular or cylindrical shank fits into the 5.6mm diameter hole on the clamp (shown below). Tightening the knob will tighten both the rectangular shank and the dovetail at once.  
This indispensible universal holder for lathes and height gages has been newly redesigned by the manufacturer. They replace the former Compac model SP and SPA holder. The rectangular or cylindrical shank attaches firmly to any dovetail (any manufacturer) and then clamps into the tool post holder or into the height gage. The indicator can swivel into many positions and then stays securely fixed when the knob is tightened. It will also accommodate a dial indicator with a standard 3/8" diameter stem. It's also an ideal way to calibrate both your test and dial test indicators when used with a height gage and some gage blocks. Order one shank (rectangular or cylindrical) and one clamp shown below. Swiss-made. |

Interapid Indicator Swivel Holder |
This versatile Swiss-made mounting stem (axial support) shown in the diagram above is 5-1/4" long and swivels at two points. The two joints allow for multiple positioning. One end has the dovetail attachment and an opening for the Interapid 4mm stem. An allen wrench (not supplied) is used to tighten the clamp. The other end has a mounting rod which can be gotten in two different diameters as follows: - 3/8" Ø rod 74.106931 41656 ... $64.00
- 8 mm Ø rod 74.106026 41650 ... $64.00
A note of interest: there is a limited swivel of about 20% between the two leftmost joints on this holder. If you're at all handy with a Dremel and an abrasive sanding drum, you can modify the corners of these joints to give you complete side-to-side swivel.

Interapid indicators come with a 4 mm diameter stem attached to the end of the instrument. This elegant Swiss-made sleeve, shown in the diagram above, will fit over the stem so that you can attain different diameters.
