Small engineering job ...
« on: July 25, 2020, 02:11:53 PM »


Looking for someone to get this make, mild steel I guess.
Cost? Advice?

Hi Martin, before the next person asks it might help to put some dimensions down.  Or show what scale the grid is at as that helps nail down sizes.  You learning tinkercad or is that 365?


Back in the day I would have had someone to knock this up on their mills for free but sadly no more I'm afraid.

Be easier, quicker to make in brass. Why do you want it in steel, and what size does does it have to be?

Could also be 3d printed, as you have a 3d file by the looks of things.

Thanks Rich, forgot...

Light blue bit:  30 x 30 x 30mm -  slots not critical - hole for 10mm bolt

Dark blur bit:   30 x 30mmm - opposite slots to match. Shaft 14.5 x 40mm

 It's for a "Turbo Encabulator"   {-)        .... look at it on Utube!

Actually is for a high mounted desk mic stand the I use as a camera mount.
 I would like this angle adjuster so I can tilt it over further and thus lower down.

Have you considered having it printed in plastic. Nylon would be very strong. A few tweaks to the design would make it cheaper to print e.g. reducing the volume.

I did consider a 3D print but there's 2 or 3 Kg hanging off the thing and some pretty firm springs in the arm....   {:-{

Martin...all a point of balance  %) 


Best remember these devices or 'cantilever arms' [with internal springs] are designed to keep the nominated weight stationary in each/all desired positions by each spring working with or against each other


If you added a heavier '2 or 3 kg' mass to replace the lighter weight microphone  .....you may well find the heavier mass slowly self lowers  O0

I'm sure that there's a reason why not just extend the length downwards of the rod holding the camera mount to give more drop? As Derek has it, it's all down to relative weights and that's going to depend on the biggest lens you're planning to use. O0

There's a computer monitor in the way, I want to be able to push arm up, out of the way once I've finished videoing.
These mic stands are ideal for quick & easy camera mounting, move to position and it stays there, but they are designed to work just down to table level, I would like mine to work about 500mm below the mounting point.

( Plus the Rode PSA1studio boom arm is renown for smashing monitors &/or giving users black eye's! ... but that's a story for another time )


..... I'll take some photos.  :-))

They're about 150k, so bit expensive at the moment. However lots of bureaus have them. i.materialise is good as you can upload your model for free, and get a quote. It's polyamide (MJF) material.

That looks like a Gopro style camera mount.


There are plenty people selling aluminium ones like these:

Check Ebay there are loads of CNC machined Gopro type mounts for sales quite cheap too!
