Sorry for the chain of posts

After more experimentation, it looks like the original body tube has the same ID as a BT-20 but is much thicker walled. Does anyone know of a body tube that has an ID about the same size the OD of a BT-20? I checked the chart at Semroc and didn't see a perfect match, but not sure how much is "close enough". I also asked Carl via the contact form.

Open to other suggestions as well. Thanks again!
