We've used nitro before to shrink sleeves to insert into bores. Problem is we don't have the proper flask to store it, so nobody will sell it to us. We usually borrow from another shop, but they closed. Dry-ice is easy to get ahold of, just wondering if anyone has used it for shrinking and could give me any tips?

I read that adding dry-ice to rubbing alcohol will make a very cold liquid which I can submerge the sleeve in.

I have two sleeves, one is about 2.5" OD, the other about 3.5" OD. Both with about 0.150" wall thickness. Was planning on making 0.002" larger than bore size and freezing. We usually do about 0.006" bigger with nitro.

Any comments appreciated.
