Today motor mounts for J1 and J3 Op1 and final parts, I was perhaps a bit heavy on the chamfers Tomorrow I hope to get the turret platform
Quick update, today I was able to work on the J1 turret platform, pretty straightforward setups with OP1 doing most of the features And the other...
Next was J2 turret housing and this part really challenged me. I did offered a fresh end mill as a sacrifice to the gods of CNCs but that wasn't enoug...
And now J2 ARM - very close the to limit of my CNC envelope, this is OP1 And the finish part (3 ops)
I went the broaching way for the first pulley (let's see if I can keep it up for the 5mm...) - first time broaching and it went surprisingly well
And finally I was able to do some assembly - J1 mechanically completed !
Moving on to the second join, the J2 tension ring was a bit tricky to machine due to the thin thickness, I used the CA glue work holding method and it...
The J2 spindle was a bit more complex that I thought initial;y. I had to alternate lathe, CNC OP1, lathe again and CNC OP2 and 3 But the result ...
Last but not least I'm taking some liberties with the design of the covers - the J2 cover will keep the AR3 logo but I added a shark to the J5 cover
Here is J2 Motor Support, the part was 90% done and the last drilling operation was very tricky and the bit wandered and ended up breaking. Had to scr...
On the right is the first attempt at J3 spindle - this is what happens when you don't verify your tool stickout in CAM Vs real life.... After the...
While the CNC was busy with J3 spindle I could run the lathe and create most of the features for J3 bearing cup. Then run a final op on the CNC for th...
It took 6 ops for the J4 turret housing but I am very pleased with the result - one of the cutest parts I machined I'm now machining a busing in...
This part - the J3 tension ring gave me a hard time - final thickness is 2mm so work-holding and order of operations are critical. I ended up us...
And this is J4 Motor mount limit arm - 3 OPS and routine toolpath with good ol' rectangular parts you can hold in a vise. And while the CNC was b...
