Nice work Kevin, looking forward to the rest of the build. And thanks for promoting my channel, much appreciated, I've had a couple of requests for the plans this morning, fantastic!
Gday Kevin, this is a great tool to make and a very handy tool to have, I really enjoyed building mine, looking forward to seeing the next part, Cheers
I got the plans thank you. I was wondering if it could have springs in it to keep it centered so that it doesn't have to be guided into the hole by hand. the reason I want that is because I want to use it in my cnc lathe auto tool changer turret and have it not crash on the part face but actually go into the hole without the assistance of guiding it in by hand. do you think the spring pressure could be soft enough to just hold the floating reamer on center; but not allow it to affect the free-floating ability?
@@Machine_NZ not fair to say "go for it; I'll watch" aren't you gonna help me? LOL you should see my auto tool changer for my cnc lathe. i designed it and its fully pneumatically controlled with timers and a proximity sensor for centroid acorn. I'm doing the plans for the 9 cylinder radial engine that I got from Germany and jet engines and an dynamic balancing machine controlled by an open source computer program. just trying to finish up the ATC turret
is is a “universal” ACORN Lathe tool turret PLC program and supporting files that facilitates the operation of a lathe tool turret. This document covers the timer based turrets that use a single input for homing and a single output for rotating the turret. V4.80+ allows the use of the wizard for those who wish to use the beta ATC PLC. The wiring diagram for the previous beta PLC’s is still included as a guide on how to generally wire the Acorn, however inputs and outputs can be assigned to any input or output via the wizard. Installation: 1. Install ACORN CNC12 V4.80+ on PC System. 2. (Optional) If upgrading restore report from previous version to retain Parameter settings. 3. Extract all files from centroid_acorn_v480_lathe_universal file into the c:\cnct directory and overwrite all files. 4. Start CNC12 and open the Acorn Wizard. Assign Drive Type and Required I/O for your system and ATC. See the Inputs and Outputs section below for I/O that is used by this particular turret setup. Write Changes to CNC and follow on screen prompts. 5. Set the following CNC12 parameters. From the main screen press F1(Setup)→F3(Config)→137(Or User specified password)→F3(Params). A. Parameter #6 = 1 B. Parameter #160 = 1 C. Parameter #161 = Maximum number of tool positions D. Parameter #820 = 1 (Sets Machine type to Lathe) E. Parameter #830 = 5 **NEW** (Sets what t ype of ATC you have for PLC and macros, values are subject to change in future so ensure to check documentation on every update) F. Parameters #975 = Amount of time in milliseconds the turret takes between each tool position.
Initialize the turret: The included M18 macro will “home” or “initialize” the turret. M18 rotates the turret to seek the turret home switch and waits for ToolTurretSyncBit, to trigger and sets the current turret tool position to 1. The turret MUST be initialized prior to performing a tool change. If it’s not, the control doesn’t know the current tool location. Press F3(MDI) from the main page, type M18, and press Cycle Start. After the turret has been initialized, the CNC12 software will keep track of the turret’s location. If the Tool position is ever lost..for instance in the case of E-stop being pressed in the middle of a tool change, an M18 will need to be issued in order to “re-home” the turret. Indexing the turret: The Index Turret button is used to index the turret. When the Index Turret button is pressed, the PLC program will see what the current tool position of the turret is and move to the next tool. If its at the maximum tool position then it will move the turret to tool position 1.
Hello Kevin, Nice work... and nicely explained why anyone would need a floating reamer holder... do you need it for an upcoming job or just to have ready should it be needed... Take care. Paul,,
Greetings from one Kevin to another! Enjoying the series immensely! Just thought I should ask, what is the OD and length of the 4140 material that you are using for the tool parts? Thanks in advance, and keep up the great content! Be well.
Nice work Kevin, looking forward to the rest of the build. And thanks for promoting my channel, much appreciated, I've had a couple of requests for the plans this morning, fantastic!
Great the video prompted enquiries. Thanks for making the plans available. Regards kevin
I’m enjoying this build series Kevin. Some great tips in there too mate 👍🍻
Cheers Aaron. Thanks for watching....
G'day Kevin. Very nice work mate. This is going to be a fantastic build series. Looking forward to part 2 mate. Cheers, Aaron.
Thanks Aaron. This project has been on the list for a while. Regards Kevin
Love that trick of leaving the material before the thread at the minor diameter for thread depth!
Thanks and thanks for watching and leaving a comment
Gday Kevin, this is a great tool to make and a very handy tool to have, I really enjoyed building mine, looking forward to seeing the next part, Cheers
Hi Matty, this ones been on the project list for a while. Going to help with reaming holes more accurately. Cheers Kevin
@@Machine_NZ I’ve got cheap import reamers and using the floating reamer holder the sizes are spot on
Looks like a handy tool to have in the shop. I like your idea of using a straight shank too.
Thanks for watching Robert. Regards Kevin
Interesting video. I need to make one of these.
Thanks for watching. Regards kevin

Hi there. I'm sure there would be a way but it is quite heavy. Would be interesting to see how you get on. Regards Kevin

pretty cool huh? just enter time and tool ammount

Hi Paul, Thanks for watching. Will help with getting those reamed holes more accurate. Regards Kevin

Hi Kevin, from memory the OD was 50mm and the length I can't remember sorry.
