Mini Screw Jack
Description
This is a model of a mini screw jack I have to level a fixed leg tripod for a telescope (Orion HDX 110 EQ-G). I liked the design and thought I would share it. It consists of four parts including the base, bolt, collar, and stop. I added some knurling along the bolt, collar, and base not present on the original. The holes on the side can be used to help tighten or loosen the bolt using a small cheater bar. The stop is optional but can be added to the end of the bolt to prevent the bolt from separating from the base. I used two 3mm button head screws. I've include a long and short version of the bolt. The difference is only 4mm. With the stop and screws the bolt can protrude out from the bottom of the base slightly but not a big deal. Optionally, you may want to get some adhesive backed rubber or cork and adhere it to the bottom of the base. A proper thickness can resolve the issue with the bolt being too long or you can just use the shorter bolts. Please note that I have also included a concave and flat top version of the bolt head.
