http://i273.photobucket.com/albums/jj232/brockley1_bucket/lathepics004.jpg Up to now I have only browsed the site and tried to help where I can. I thought at least one of you may have sometime tried to screwcut wood. Not easy with a single point tool. I know there are special dies out there to thread dowel but I wanted to "Do it my way" This is my dremel flex shaft end with a 1/8" ball cutter threading 4 T.P.I. (just in case anyone is interested) Peter

How are you going to do the internal thread?

Thanks for posting. Looks good. Heard that apple wood is good for threading.

Nice looking work. Looking at your setup, you could do regular 60 degree threads with a tiny dovetail cutter, one flank of the tool on one flank of the thread, and the other thread flank with the end. May have to try that ...

This is how I made a form for bending sand-filled 1/2" Cu tubing into 4" diameter coils for my steamboat boiler... I used a 1/2" carbine ball in a air die grinder on my 10" Atlas... I turned it over by hand since the lathe didn't go nearly slow enough. I use a piece of 4" square maple as the form.

curiosity got the better of me. I have to ask. Not to be confused with a stereo nutcracker, is this a mono nutcracker? And how do you propose to crack the second nut onces the game is up? :D

Brockly, once you bring up a particular photo, look to the lower right of the screen and you should see the url for you to copy. Each of the 4 urls will offer the image in different sizes. Click on the url you want and it copies to your clipboard. Then come over to this forum, position your curser where you want the image to appear and then right click and then hit paste and you're done. good luck

In one of the woodturning books I have read there is a picture/s of a head that sets on the ways of the lathe on a cross slide that uses inserts of different pitches to get the TPI you want. It holds the work being threaded. The cutting tool (think small mill cutter) goes in a collet or drill chuck (the horror) in the lathe's spindle. Primarily used for making screw on lids for turned boxes. IIRC the book is by Richard Raffin

But then if I was shopping for a wood lathe and money was not the main concern I would really think about one from these guys. I talked to the owner at a wood show a couple of years ago and we had a nice talk. He has a backround as a tool maker/machinist and I expressed my feelings that it would be really nice if there was a wood lathe that had a big enough spindle to take a 5C collet in the spindle. He agreed but said it was a matter of money and a certain amount of inertia on the part of the wood turning community

The link is fine. If you want to past the image, you need the one with the "bb code" in it. It will start with <IMG as I recall, and you must include the full line including the IMG tag portion.
