I started to build a finger engine similar to Bogs.
This is what my large standards look like so far:
I got a bunch of bearings at a local hobbie shop and a pirated copy of Bogs CAD software.
The numbers shown are the best measurements I could take with the tools shown. There are 2 sizes of bearings. I am guessing that they are metric bearings - the box they came in did not give any measurments.
If i convert my measurements to SI I get
Large bearing OD = 10.988 mm
Small bearing OD = 7.98 mm
Both ID = 5.0038
Now I need to decide what size hole to make for them. And how to make the hole.
I do not have a boring head for my mill but I am considering making one, I do have a 4 jaw chuck for the lathe.
What size hole should I be trying to make? How accurate does it have to be.
Sounds like such a simple thing - make 2 holes for the bearings, but I have been thinking about it for a couple of weeks and I am still not sure which way to go. Any advice would be appriciated.
