Getting reamers sharpened

Morgan uprights are a other odd one

So how do you do blind holes?
They don’t have a long start taper

Use a D-bit? You won’t do a blind hole with a hand reamer. A reamer does not cut right the bottom of the hole. Hole must be slightly longer and will have a small bevel at the end. One reason is because the reamer should be floating in its holder and needs the small bevel/taper of the machine taper to centralise the reamer on the hole to be finished.

I use machine reamers for blind holes nearly every day and sharpen the things
You said machine reamers have a taper like hand reamers. None I’ve come across have.
Machine reamers I use are either morse taper or chucking not floating
In a situation where I need the reamer to float I use a David brown floating reamer

Yes that's the style we use, it passes through the bronze bush and is supported I the roller bearing so it cuts straight.

Did I? Read it again. I said the taper was less on a machine reamer - but not non-existent.

How do you ream right to the bottom of the hole. It must be longer than required as you cannot cut the botyom of the hole with a reamer.

Other than the tiny lead you can ream a blind hole especially when you’ve drilled just slightly under so the chamfer left is Minimal defending something that everyone knows has bored the **** out of me now

Machine reamer has no taper just the cutting edge lead
If I’ve got to make a interference fit I’ll put one up in a cylindrical grinder and kiss the outside

And when that doesn't make the hole big enough stuff something in one flute.
