3D Printed Spirographs
Nice dinor, would it be posible to do it in black and white ? colored ink gets expensive plus like to do different colours.If in B&W one could print on coloured paper and have any colour or make a puzzle .eyes and mouth can be glued on after in different colours.Thanks anyway,our 3 year old liked the preview. baby ...sauros ,i dont know them all yet !
Have to agree on this one, there is nothing more a hindrance then having metalbits and splinters on your drill tip spinning and you are trying to locate the centre punch dent. I just recently build a de-magnetiser as it was getting bad. I love magnets in the right places, and they are great in the workshop, but not for drills. I have a magnet for holding the chuck key.
Classic Oak Book Press W/Dovetails
Many a machinery supplier has them as spare part or replacement item ,with the "nut" as well, buy these before building,If you are lucky,there used in bench vises for metal and larger for timber. check flea markets. it may help to fit the gland into the top bar.it has to stay fixed,can be loose but not rotating.
Very nice in miniature, if build for real use,I would fit the flange from under the cross bar,for strenght. still would need to "hide" the top part. The screw type is not important ,it could need some dulling of the sharp treads . Love the use of oak,nice patern.Compliments on the idea and relative simplicity and excellent explanation.The novice should be able to follow.

Yes that would work well,specialy if it is a transformer based unit with a large capacitor in it! The smoother the better.
DIY 4X5 Camera Scan Back
Nikon has a patent for digital back,but doesn't make one. Just to prevent any other person or manufacturer doing so! I know the person that was involved in writing that patent. Sad but it shows the calibre of the brand, comercial only.not for its long time supporters that are stuck with film camera's . good question and I hope someone finds a way around,for hobbyists .
Nice to see some invention here,simmular metal unit is available on line,very heavy metal as it is for sandblasting. I would like to see a model like this made with hinges or clips to be able to dismantle, it takes a lot of space. Good try and should do for most small jobs including spraycan jobs for hobby .

link to TIG welding is broken
Thanks for your great correct explanation,I would highly suggest to those that want to get involved with this stuff to read a lot before even thinking about building their own. You need to understand the electrical side ,ohms against volts and then the amps going though it all. Then get involved with the pyro side. reliability and safety is the main consideration Jv
I buy on regular basis the black glue sticks from a company called Radio Spares RS well known in Europe and Australia,Malasia .relative small packs at fair price.They may have a waiting /delivery time so don't order the day befoe you need it.
Very nice and useful also as load for using Ipod into larger amplifier,we found some loading is better for the quality of the sound. I also have made a simmular one for high power amps as I didn't wanted to blow my big Infinity speakers $$$$.At least a good inspiration for the next project. Thanks. Jv

Its a cleaning process not polishing,so you will need to polish it to passify the surface.
