Dual Needle Gauge - A Boeing 737-800 Homecockpit #49
After I have built my first single needle gauges I now made a next step forward to the "Duct Pressure Gauge" - a dual needle gauge. This time with the help of my laser I was able to design some filigrane needles and angraved and filled them with the wax method. This gauge will be part of my pneumatic system panel.
Materials used:
- 3mm clear and white acrylic
- 4mm acrylic shaft
- 7mm acrylic tube
- 2 servo motors
- 4 female and male hex standoffs
- LED stripes for backlighting
In the download package you will find all the files you need to cut out all the needed acrylic parts at home.
Hi Mickey
Would you confirm the dimensions of the 7mm acrylic tube please. I assume 7mm refers to the OD with an ID of 5mm and the 4mm acrylic rod runs inside the tube. Is that correct?
Thanks

Hi Mickey,
I downloaded the files for this gauge and now trying to fabricate it. Unfortunately, I am unable to extrude the drawings for both needles to make a solid body in Fusion 360. I have no difficulty doing this for the other components. Can you help?
Thanks,
Graeme Moir
Thank you for the advice. The outlines of the needle drawing weren’t closed completely and fusion seemed to have some problems with the inner circle too. I have made some tests now and updated the files. With the new dxf files for the two needles it should work.
Hi Mickey,
Many thanks, that fixed it. Appreciate the work you’re doing here for all of us builders, great job!
