Just a few more of my creations (will seperate them over a few posts). This first one I made when I started making my tall garden baskets. I wanted something to help with threading the bars and thought of this.
I did a search when I made this and couldn't find anything like it except for pipe threading tools. I did wonder if I could get a patent but abandoned that when I found out what was involved. However it was still in the back of my mind that someday I might sell the idea or maybe even churn them out to sell myself, so this is the first time I have shown the pictures of this to anyone.
Oh well enough trumpet blowing its basically a die-nut stock with a guide to ensure a nice straight thread.
They are made to suit one size only with the hole in the guide being slightly over size so it does not snag when cutting thread on possibly irregular bars.
the die-nut is set with a bolt of the size you want to cut adjusting it with the 3 bolts (in this picture at least grub screws would be better but I didnt have any the right size) until the stock runs smoothly up and down the thread.
There are holes to help the swarf to be cleared. one of these days I will get around to making some decent handles for it too.
The one shown here is for a M6 die-nut but I have also made one for a M12 to use with the baskets
