Workbench Build - Splayed leg French Bench #3: Tap for Wooden Nut

Friggin awesome.

I was wondering where my damn chisels went!

Wonderful job Mauricio. Quite resourceful.

Great work, Mauricio! I see this coming in handy for all sorts of things!

Thanks for the blog. I have added this to my favorites, to be frefered to when I get around to doing the same thing.

Outstanding Mauricio. Thanks.

Mauricio, I am glad you decided to do a blog on this. I originally saw this done by Carter also, http://lumberjocks.com/CartersWhittling/blog/27648 but it is encouraging to see another woodworker repeat his method. I will be trying this method when I start my work bench project. Great job!!

Thanks for all the comments guys and thanks for watching.

Luv2Learn, Don – or anyone else thinking of doing this, I encourage you to try, it doesn’t take that long and is not hard. I would equate the difficulty level to making a wooden plane for the first time.

I ordered my dowels because I don’t have a lathe and besides the grinder I haven’t used a power tool yet. I won’t need it for the cutting the threads on the screw either.

However, I am contemplating making the router jig for cutting the threads on the screw, especially since I already have this practice nut made, I can easily turn it into the thread cutting jig. It would be handy if I plan to make more.

Scott, what do you know about these medical chisels? What do you use them for as a doctor?

I’m pretty sure they are stainless steel, especially after seeing the sparks the steel makes at the grinder.

Mauricio, we call them osteotomes. I use them quite often to chisel bone i.e. taking a bone graft. Most surgical steel is 316 stainless.

^No metallurgist here, give me the Cliffs on 316. Don’t mean to be gory, but surgeons leave good looking stuff in my patients. I autoclave it and put it in a box. No one’s asked for it back yet. Is it worth shaping into something? Mauricio, while your friend is at it, hit up the radiology dept. for spent lead. Reloaders love that premium stuff.

Maybe THAT is what happened to my osteotomes. I left them somewhere and I can’t find them. Just kidding (before the lawyer types can’t sense the humor)

Ha Ha ha, Al, your patients are not usually living if I remember right?

It held up well in this application where it was scraping the wood out for the nut. Here is a little info I found on it. My guess is it is Medium Carbon Steel. I dont know if stainless steel has the edge retention of the high carbon steel we use for woodworking.

http://www.azom.com/article.aspx?ArticleID=863

“Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). Grade 316H, with its higher carbon content has application at elevated temperatures, as does stabilised grade 316Ti.

The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.

Key PropertiesThese properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.”

Al, I bet he can get the spent lead, I’ll ask. ;-)

Thanks for the close-ups and explanations Mauricio. Definitely one for the favourites. I must try this.

Thanks Brit! Hey I’m getting Favorite-ed by some woodworking studs. I’m honored.
