A DIY Secret to Easily Turn Screws On Your Lathe!

Hi everyone,

I think anyone who has ever had to modify existing screws without building them from solid, for example due to the excessive length, but also due to the size of the head: it happens that this must be less thick for example or with a smaller diameter.

In this video I show you my version of a simple support with 2 screws, one inside the other, the smaller one acts as a block for the larger one, which being cut in half expands by opening (when the smaller one pushes) a few tenth by locking into place and pushing the screw to be modified.

The screw to be modified is mounted frontally, on the thread side or on the head side depending on the modification to be performed!
However, the force of the tool tends to tighten the screw, in favor of safety.

Hope you like it!
Alberto

To knock down the head of a bolt like that, --------- why not do it the real easy way

Thread a nut onto the bolt and then shove the nut into the three jaw, then get at the head of the bolt with the tooltip.

Saves wasting time making that "abortion", eh ? :-)

Thank you for the definition of "abortion", it's the first time I've received such a kind compliment on one of my creations;

what you wrote to me is correct and I already knew how to do it, but it certainly wouldn't run coaxial;

I also wanted to create something different and functional, since you don't need spanner to lock the screw in position but only to rotate the 2 knurled parts by hands.

Just because you don't see a need for such a device doesn't make it an "abortion."

Not everyone needs a full-up lantern chuck, but for a lot of folks, putting the screw in a nut just doesn't give enough control. This is a good intermediate project for someone who wants to lightly customize some screws, but isn't looking at heavy production of complicated screws, or just making do. I like it enough to have download the drawings.

Bill

Very clever device for the modification of screws and bolts. I also downloaded your excellent drawings.

Phil

Thanks Bill, i think so !! :)

Hi Phil, happy that you liked my simple device and my drawings too; it is the first time that i upload the drawings, i will try to do the same in the future post !!

A big ciao from Italy Phil,

Alberto.

Nicely done.

I like the idea of being able to work on either end from the same fixture. It gives the ability to hold any screw you have a tap for.

Another project for my "to do" list

You meant: 'abreviation' in the sense of 'shortcut'.

Hi Piper184, happy that my simple device will be an inspiration for a future project !!! A big Ciao from Italy, Alberto.

Ciao Alberto! Thank you very much! This is a great project and I hope to make one soon!

I just saw on your YouTube channel that you're located near Venice. We just came back from Venice last night. It would have been nice to have stopped by and traded stories with you, perhaps next time. (We live in Stoccarda and come to Venice at least once a year, it is one of the coolest places on the planet!)

All the best from your neighbor in Germany, and keep up the good work!

Cab

Ciao Cab,

thansk for your nice message to me: yes i live at 1.5 hours of car from Venice, it was 2 years that i did not go to Venice for the Covid problems but now
here it is more or less finish, so i hope to come back to Venice soon!! I like so much Germany, I went to Nuremberg by car, easy and with beautiful roads, black forests, a beautiful experience !!

Venice is a unique city, which shouldn't exist since it rests on ancient wooden poles...next time you go try to look closely at a "gondola", the typical boats for tourists: they are not symmetrical like all boats but built off axis because the boatman is positioned off axis;

in addition, the boatman always moves the oar in the same way, but depending on where he places the oar, the sling goes forward / backward, right left ..... it's an engineering miracle !!

Ciao Cab, see you soon !!!
Alberto.

Not the sort of post that we usually get on this forum. May I suggest that the moderators consider whether continued membership adds value to the forum.
