little tip if you ever have to hold short parts in a ER collet like you've done here. Basically the collet will try and bell mouth if the part being clamped is too short which reduces your clamping force massively which is a nightmare for anything except for like cuts. if you cut a short section of ground bar in the same size as what you're clamping and put it at the back of the collet you can hold very short parts with excellent clamping force and less wiggle. I hope that makes sense
You're really a dumbass you don't freeze it cuz if you freeze it that you will expand the metal you heat it in the heat it when you heat it it will make it more loose
@@crazyhillbilly48. you are wrong, he was freezing the bearing driver which shrunk it, notice how he said not to get the spray on the bearing because you don't want to shrink that. If he applied heat to the bearing the case would squeeze the bearing as it would heat up as well...
You can find any information you need in a good machinists handbook on bushing manufacturing and shrinkage at install. The bushing ( or bearing) is fine. Your install tool could have been a few thousands smaller that bore size. Different bushing materials have different shrinkage ratios. The more you make the better you get at it...
Thank you for watching! The material is called Oilite. From wikipedia: "Oilite is formed using powder metallurgy so that tiny pores are present in the metal. The pores are then vacuum impregnated with an oil to improve the material’s bearing ability"
I think you discredit yourself to much on this and should realize you did a fine job with that situation. Tolerance could of been a little tighter but given the weight oil that goes in it I think it'll be fine. Only thing I seen that you missed on the new bearing is the oiling v groove on top and oiling oil on side of it for shaft lubrication.
