View Full Version : Coffin smoother wedge rebuild update

Hi gang,
I finally got a chance to mess with that wedge I made for my old wooden coffin smoother. I used walnut for the new wedge and followed the directions I found at the Norse Woodsmith site (http://norsewoodsmith.com/node/25). Side note here: That is one heck of a site! It is just chocked full of great information!

I'm glad I let this sit for a while before I went at it again. After making (2) wedges and not having either work I figured it was a good thing to leave it alone for a bit. As it stood, one of the wedges wasn't as bad as I had thought. So all it took was some careful chisel & rasp work.

It turned out that the abutments are not quite at the same angle. So I had to tweak the wedge a good deal to make it fit perfectly. Before this I used a belt sander to narrow the sides of the iron by a hair, and flattened/polished the chip breaker. But it was getting the wedge to fit right that did the trick.

Here's some shots of the smoother after trying it out on a piece of cherry.

After I was confident that I had the wedge sized correctly, I cleaned up the corners and used a rasp to steepen the incline on the inner "ramp". After all the work I did making sure they fit, I left all the sections that contacted the abutments alone!

Here's a shot after I tried the smoother on some ash.

The next think I'm going to do is either laminate a new sole onto this plane, or just install a insert at the mouth. Either way, I have a nice piece of pear that will work.

BTW, I was examining the front of the plane this afternoon and noticed the maker's mark. It's partially worn away but I could see a star and some letters. Anyone know of a plane maker that uses a star in their logo?

Looks good Dom! Nice save!

Dominic - The most likely maker is Auburn Tool Company. It was in business from 1864-1893, when it merged with Ohio Tool Co. A side note is that Auburn used prison labor contracts extensively during its existence - this was also true of the T.J. McMaster plane co, as well as a few others.

There were a few other makers that used stars in their stamps at various points, but their products are a lot rarer, so not as frequently encountered.

The criteria I use when I'm fitting a wedge is the "thunk" factor. When it is fit correctly, both the left and the right side of the wedge should hit at the same time all along their length. If you tip the toe of the plane downward and drop the wedge in, and it is fit correctly, it will seat with a satisifying "thunk".

I know that this is not very scientific or quantifiable, but it works for me.
