Re: bearing punch
The ‘collets & springs’ of the Hotpoint kit are available separately, I don”t think the collars (which is what I think you meant) are though 🙁
Any local engineering workshop (or Blacksmiths) should be able to make up whatever type of drift tool you require. Machined on a lathe to fit whatever size bearing you wish. Just show them a sample bearing and they should be able to cut one from various steel rod sizes. Some can also temper them for added strength. 8)
