After fooling around for a couple of weeks, I've finally completed the 3 rollers... Learnt quite a bit along the way on cutting such small wheels. Bulk of the time were spent on the notebook working on the CAD drawings and setting up the roller blank. My breakthrough came when the Thai hobbyist (Instagram handle max_pannara) replied with his method of holding down the rollers. But, unlike him, I'm unable to remove the completed rollers by plying them off with a flat head screw driver. I did manage to work around the problem by drill through holes in the recess holding each rollers and tap them out from the back. This is not very efficient as I'll have to indicate the plate in again after each batch. Since I'm will not be making many, I'll live with the trouble.
 | A note on the 10k RPM Pully upgrade from Sherline. I didn't adjust the preload in the spindle as mentioned in the instruction as it will introduce more play. While doing the 3rd design (right most) which took the longest to machine, the spindle housing did get a little warm to the touch but not burning. I'll monitor when I start cutting the batch of 10 after the design has been chosen by FJ, the person commissioning me the job. |
 | The higher spindle speed did cut cleaner, leaving me with burr free finish. Love the result. Definitely a worthwhile investment. This pic was taken just after the machining - very clean... |
I'm looking to take videos of the machine in operation. Saw from the iPhone App "Geek" that a GoPro look-alike is going for about SGD 50 to SGD60 excluding shipping. Very tempted to get one to try but I've to control my spending.
Ok, that's all for the day. Hope to update you folks soon on my activities in my home shop.
Be blessed!
