I thought I’d do a little update for the post that I originally put in the “Stuff you have made today thread”. I’ve created this individual thread so I can keep everything together.
Something that looks a bit like a tipping die for a bead roller.
It's a first go at making one so not sure if my dimensions are suitable as I've just copied it from images off the internet. None of the sellers are daft enough to provide dimensions as they are pretty simple to make. I need a skateboard wheel or some firm plastic to make the part it rolls against. 22mm ID to fit my rollers. The tippy bit is 3mm wide with a bit of a radius done with a file on the lathe. Grub screw is M8 so it matches all my other rollers. It might need a little spacer on the back as the material I used was a bit short. It's not hardened but it only needs to upset 1mm steel or ally sheet so I think it should hold up.
This is what the Chinese will sell to you for about 40 quid.
This is what it does on the bead roller.
Update starts here.
Skateboard wheels have arrived. Specifications on the packaging. Four wheels, eight wheel bearings and four axle sleeves/bearing spacers or whatever for £12.99 delivered from Ebay. The hardness, or shore rating, is 82a
They have a flat side and a concave side. I've tried to show both in the picture below. I''ll be working in the middle of the wheel so I dont think it really matters.
They dwarf the tipping die a bit. Might be a bit on the big side.
First thing to do is was to remove the bearings. I had assumed they were glued in. I later found out they weren’t. The bearings are 22mm diameter. They sit on a step, 20mm across that sits in the middle of the wheel, so you cant press them through and out using a bearing press. I was lucky that as I mistakenly applied pressure to the bearing the base of the wheel squashed and flattened out widening the hole on the bottom. The bearing on the bottom side promptly fell out. This allowed me to push out the other bearing conventionally from the reverse side.
Step in the middle of the wheel below. You cant push the bearings out because of it. (Well, you probably can if you are an animal.)
The wheel was put in the lathe and I bored out the 20mm centre to 22mm as the rollers are 22mm diameter.
