I could make a boring tool holder for 1/4" router bit and use their tool post?? I will have to mill or file a flat side on the round stock.? I really like my Whiteside SC64 bit... it works so beautifully on my CNC router.
For now, I think this is something I can do so I can see what my CNC lathe can make. Thanks - Tamra? |

I am relieved that I found the sherline standard toolpost that came with the machine, and they have one that will allow use of a 3/8" round bit, but not 1/4" and my router bits are 1/4".
At $21 this seems pretty inexpensive.? I do understand changing bits as I do this frequently on our CNC Router, but I'm just trying to do some cuts for now, as I don't know if I will be able to really do, what I want to do with this router.? ? I know I do not have any 3/8" router bits though for small scale work, and Whiteside and other mfgs make it so easy to update your tool profiles, so will have to find a way to update this with inserts, etc for standard tool bits from the metal world. Sherline is closed for shipping until May 4th, but if you need anything accessories are 20% off right now, and they have so many options and the best website in my opinion for documentation. Thanks for the kind assistance and welcome.? ?I will look at the other QCTP options too. Tamra |

Heated bed leveling. Prusa I3 type printers. Geeetech, Anet.
A simple way to have consistent level beds.So very important in good bed adhesion. I did not like the 4 x corner adjusters with springs and screws and the use of a paper shim between glass and nozzle, IMHO opinion very "Heath Robinson" so I replaced with 4 x delrin risers individually accurately?faced to the 4 corner heights. The DI checks parallelism across the whole of the glass by resting on the X axis rails.sliding along the rods, and also moving the Y axis front to back. Simple hook on hook off shoe. holding the DI. Dial Indicator.See photos. If a X axis parallel adjustment is required and very rarely the 2 x Z axis steppers connected to the Z axis screws can be moved a smidgen in disable mode to accommodate. Note one photo shows the glass bed frosted, I bead blasted one side of the glass, excellent for ABS filament bed adhesion. Use a standard clear Pyrex type glass for PLA. Hope of interest. -- John |

Introduced a new hashtag for our woodworking members.
Hoping to receive posts from interested members. Many hobbyist routers and lathes are now CNC or digital controlled. Thanks -- John |

To follow on with Tamara's recent post ref QCTP and holders and profile tools.
A photo of a 250-000 QCTP tool holder 3D printed in ABS: I don?t recommend this approach for holding turning tools cutting metal, but for holding a dial indicator or in this instance, a? concentric leveling tool, (IE Bar with a roller bearing on the end,) then frees up a steel tool holder for? other real work. Cost to buy a QCTP steel holder about $20, cost to 3D print about 0.75 cents. Hope of interest. -- John |

Hi Tamra
Take a look at this link. If you purchased a QCTP Quick change toolpost with holders from say LMS, at least one of the tool holders has a Vee base for holding? these types of round shank tools. There is a myriad of different round nose tools (diameters) to choose from. 2 flute round nose router bits can be used, but you would need a bar with a hole in it, not a big deal, but a designated QCTP is IMHO the way to go, QCTP also allows you to change the c/line of the carbide tips to the center line of the lathe spindle. Important. -- John |

Put round bit in square stock, Mike this makes sense.... hmmmm... the Whiteside bit is 1/4" round, should be easy enough to drill a 1/4" round hole in square stock...?
Bill, I do not have a boring bar toolholder for any of my lathes... I will look at these options, and I've never purchased a QCTP, either, so perhaps the Sherline lathe will be the one that gets a QCTP.? I really like Sherline, though and appreciate the commitment to the scale model world, the made me an internal square WW collet when I requested it by visiting the factory in person in 2018!??

Hi Tamra
Welcome to the forum. I assume you are referring to 3D printing of a lid and base for holding some involute gear cutters.?? File creation approx 1 1/4 hours for both, I use Mastercam to develop the CAD and convert to STL. I use Slic3r for the gcode generation. 1.5 and 2 refer to the Metric module of the gears.? Imperial commonly known as the DP, diametrical pitch.or basically the size of the gear. 20 DP being very common with a pressure angle of 14 1/2 degrees. For comparison, a? #1 module is equal to 25.4 DP.? a # 2 is 12.7 DP. pressure angle 20 degrees. If you have a passion for making your own gears, we can help you start on this forum. A good text book is from the Workshop Practice Series. # 17 Gears and Gear Cutting by Ivan Law if you are new to this important part of out Bobby. Thanks ? Mod 1.5 -- John |

Do you have a boring bar toolholder for your lathe? That and possibly some sleeve collets should let you mount a router bit in your lathe. I put an AXA clone Quick-Change tool Post (QCTP) on my Atlas TH42 lathe. It would be FAR too larger for your Sherline, but there are similar toolposts that will fit the Sherline. Sherline sells a QCTP, but it's a bit pricey. https://www.sherline.com/product/2250-quick-change-tool-post-and-three-holders/ The boring bar tool holder is the one on the left in the photo. LIttle machine shop has an OXA toolpost that will fit your lathe, as well. https://littlemachineshop.com/products/product_view.php?ProductID=4039&category=-419988835 and it's considerably cheaper than the Sherline. With your lathes and mill, you should be able to make your own, if you want to, as well. http://www.toolsandmods.com/lathe/mini-lathe-qctp HTH! Bill in OKC William R. Meyers, MSgt, USAF(Ret.)

I called some local pros and explained my issue (they work on room size equipment) and asked for some help... I dropped it off on July 3, and got it back last week.?? Now, I am ready to do a test run for the CNC lathe, but I need to put a tool bit in my database, and I use router bits that are round.? How do I use a round router bit in a tool post that is designed for square metal bits?? I can imagine my conversation with Whiteside is not going to be an inexpensive conversation.?? Thanks - Tamra |

This video is from the Dallas Makerspace... tool post for a sherline lathe uses a square bit.? I could probably use an insert tool bit, but since I have the most experience in the CNC router world, and I want to make tiny staircase spindles, I had naturally thought I was going to use a whiteside SC64, but I can't put a round router bit in a square based tool post.?? Actually, I don't think I have a tool post for this machine, so will have to order one from Sherline today.? I paid for a class scheduled at Marc Adams at the end of April 2020 so I could see Randy Johnson's solution, assuming he was going to use a CNC lathe add-on to a router application but the class is postponed or delayed and another COVID 19 Casualty, so it is going to be a trial & error for now.
