Borescope pics in the Black Powder Cartridge Forum

[oldracer]

I bought a borescope yesterday at Harbor Freight and the one I bought takes pics AND video and it's price was reduced and the girl at the register gave me the 20% coupon on top of that! It works pretty well and I posted some pics I took this morning. The barrels on my older Rolling Block and the new Sharps are pretty mich spotless!

How much was it and what is the smallest size caliber you can use it in?

[Doc Highwall]

I just found it on your post it is 8.5mm or .3346".

There is a 90 degree mirror attachment that slips over the end with the light and makes the diameter a bit larger. For $200 or so I think it is a pretty handy tool and I just wish I had one when I raced my vintage sports car as there were a few times when I needed to look inside a spark plug hole.

One will marvel at thedifferences in the work INSIDE of their barres.

Best I have is an 1886 made in 92 . . . must not have seen much black.
