Gentlemen :

The posting yesterday of the rotary tool holder was the pretext for this intended project of a propeller cutter that I named The BullNoser . Although the pictures of this are in my shop's bench vise , the BullNoser is intended to be mounted on a plywood base or the bench top .

I FLY ! I bust a lot of props in the process . Learning the ACRO modes of flying for multi rotors does consume props . If I am lucky and don't bust a complete leaf off of the prop , I usually just zing off the tips in the dirt . Most times , this leaves props which can be shortened to a convenient diameter while ensuring a proper Bullnose radiused tip . This project makes that operation a snap ! Practically , it takes longer to mount the prop with an adapter to the 3mm center shaft than it does to cut down the prop itself .

A decision was made early on to have the central cross slider platform be made with a 3mm steel shaft that was salvaged from one of my crash victim motors . This shaft is press fit into the slider hole with gentle , but firm tapping with a hammer . A standard sized prop adapter is used to secure the prop to be cut down with perfect alignment . The slider IS adjustable for the prop leaf radius and has the ability to be locked into place to ensure accuracy . Future mods for this project would include a measuring rule but is optional at this point in time . Important to NOTE that the 8mm steel rods used for this project were salvaged from an old computer...Continue Reading

Gentlemen :

25,000 reads on my blog . Thanx to all for this recognition mates !

As I am well into the winter build projects , the Anet A8 3D printer is working the majority of the time spent in the work shop . The project presented here is of a Rotary Tool Bench Mount for the Workmate rotary tool . The dimension of the internal sleeve is 49mm which required that I add a layer of electrical vinyl tape arount the rotary tool as a shim . This will protect the tool from the four 10/24 set screws holding it securely in place . The mount has 3/8" holes which may be used to bolt to a plywood base OR the work bench in a strategic location . Having the rotary tool mounted horizontally makes it easier for some jobs .

The project was designed in a few minutes using the OpenScad CAD program . I have included the STL printable file for printing . I hope that it will serve some of my fellow modelers well as it does for me . Any comments or feedback is always welcomed .

Regards to ALL of my readers , my Aussie mates and the builders in RC world . RickC_RCAV8R
