A young man contacted me on Carousell asking if I'm also into CNC. He would like to customize some wheels, which are used as rollers on his slot car. From what I understand from him, the rollers would ride against the wall of race tracks, guiding the car along the track.
He forwarded me some pix:
He bought some blanks and would like to have them machines tongue design he wants. We chatted thru Carousell and migrated to Whatsapps with pix flowing to and fro. Based on what was told to me, i put them into 3D models.
But I find the spokes too thin at 1mm. So I reduced the number of spokes to 6 instead.
I imported the 3D model into BobCadCam and extracted the bottom edges. The features I'll be working on are the spokes since I'm given the blanks. After computing the toolpath, I ran the simulator to make sure.
Next will be to find the right sized capscrew to use. The centre hole is slightly less than 5mm, which is to be used to press in a 520 bearings. M5 capscrew seems about right but there is some tiny bit of movement. Also, the capscrew head is a tad too big. I've it turned down to just slight more than 6mm.
Meanwhile, Be blessed!
