WOODWORKING LATHE DIY

Posted by ultralajt on December 5, 2016 at 2:45 PM Comments comments (0)

A week ago I was forced to make souple of woodprint carving knifes. To make wooden handles I make a provisory "lathe" using small workshop drill pres machine. I realize how nice is to carve something from a wood stock with your own hand and chisel. It is rewarding and nice feeling doing that. But, as turning object is rotating around vertical axis, it brings a strange feeling.. like world is canted for 90 deg.!

I give her name VESNA after Slavic Goddess of Spring.



 

So, I start with a hand drawn sketch, then CAD drawings and also for the first time I went to 3D model design an...

As explained at Land of hayracks Mu...

Unfortunately I was unable to make 3 axis TB6065 control board to work. I use settings as they came with the board on a small CD, but it wont work. As I knew other buyers of this controller solve problems in various aproaches, I try to use pin and ports settings as found on various Internet sites for that board. It didnt work for me...  I was playing with settings whole yesterday and today I finaly loose patience.

O.K., the board cost me only 35€, so no big deal...but it is a...

Today I was working on "Z" axis, its motor mount and "Y" axis threaded rod assembly. It is not finished yet, but roughly assembled.

I need to finish some details and purchase all the bolts of the proper length. Now I just use bolts that lay around in my workshop, so many of them are too long or with inproper head style. Probably tomorrow will replace all these bolts.

And it is a time to order some tiny items for installation of the "X" threaded rod, motor-rod couplers..

I started to do some actual work in the workshop on my new CNC router last evening. I was working on the main frame basic elements. There was a large cross section aluminum profile to cut. It was not an easy job, as cross section is ~50x150mm.

But first, some general data for this new machine.

Awerall dimensions: 1750 x 920 x 620mm (L x W x H)

Working space: 1430 x 500 x 100mm (L x W x H)

This router will be mostly used for 2,5D carving of thin plywood, balsa...

Sometimes it is not bad to put a project aside for a while if you feel that you are going anywhere with plans&drawings. Feeling like a dog who is chasing his own tail, just runing in circles! 

So, after a short break, I terurn to my Galeb (Gull) vintage Sailplane project. I can se clearly now :roll: and decided to make some changes in the structure of the model design.

On the rudder I thined the lower part of the "spar" area as torsion is resisted by diagonal ribs at this...
