I really like that DTI Bore gauge! Here is some more tooling and some more progress on the R8 1" holder. Pictures is a DNMG Tool holder and a face mill arbor (straight shank). The DNMG Tool holder was a bit of a challenge because of the 5 Deg. rake angle (compound). I don't have the right...

SOLD!

I have been tooling up since I started machining, which was probably 1.5 years ago. As you all know, tooling isn't cheap and since I have a new addition to our family, i'm on a budget! Opposed to buying a bunch of tooling, I decided to start making various tool holders, arbors, and various...

Yes I am, thank you though. That is partly where I got the inspiration for my project. The ELS kit is fairly reasonable priced as well but I wanted to give it a shot on my own. I like to learn about these types of things and i'm learning about Arduino coding so this project is right up my...

I had some of the gear laying around... Big stepper was from a kijiji buy a long time ago. I machined a 12 tooth timing pulley. I bought the XL timing belt and one of the timing pulley from motion industries (local). The hall sensor was from an old treadmill that I parted out :P Fun stuff :)

I have made a few different tool holders now and I have used various retaining screws. I made a holder for DNMG inserts and if I recall, I just used a 5/16-28 with a flat head, or something like that. The holder itself secures the insert in place and I have never had any issues with them...

I'm fairly new to arduino coding but I have a good start. I spoke with a few folks from arduino forums and that really helped!! It's actually fairly simple to sync the spindle and leadscrew... You use the arduino millis or micros functions and created an interrupt service routine to count each...

I have a bunch of 60 Deg. threading inserts so I thought I would rip up an insert holder for them. It turned out very well! Fairly easy to do. I just used 1" by 1" square bar (mild steel). Placed the insert in the desired location and scribed around it for a guideline. Setup the work piece...

Yes, the electronic lead screw :)... I have most of the mechanical part done so i'm going to be working on the code to sync the spindle and the leadscrew and some sort of interface soon! Here are a few pics of the project so far. I guess I should post this to the Project forum!
