Mill Power feed
Divided he ad:
David, Much appreciated :thumbup:
You can have a go at your veriety of mill' as soon as we figure out some workings and send you the motor parts :dremel:
FYI....(just because I mentioned it above) Personally lost my pool match :( But the team won :D
Ralph.
Darren:
Ralph, how did you make the curves on this piece?
Darren:
I spent yesterday repairing my power supply, back up and running now :)
Also I dug out another unit and modded it for the purpose of making a donation to a needy cause. Spent several hours on it only to watch an op-amp fall off... :bugeye:
All the legs had rusted through, 8 of em. I have found a source for some new ones but at 8 quid each and a min order of ten it's a no go. Shame, it was a really nice power supply at 8 amps.
I'm going to have another dig around today to see what I may be able to find.

Eye hand coordination :dremel: :) (Did the same kind of thing on my camera mounting http://madmodder.net/index.php?topic=285.0)
Normal end mill (top of pic) and controling the wheels.... Not that easy... I quite often get confused right at the end and drive the cutter the wrong way :doh:
Plan is, very small movements till you know which way your going!!
Worked quite well this time though.... Didn't need them.... It's a way larger slot than needed, but it looked better with them :headbang:
What's the op-amp look like, numbers etc... I have many circuit boards here with bits on.... Is there nothing suitable on the boards I left with you?
Got to be able to find one for less than 8 notes??
Ralph.
Darren:
I see, in that case well done.... :clap:
Don't worry about the op-amp, I've decided to start fresh and build a circuit from scratch using all new parts.
I've built the circuit, well two of them, and have been testing them for the last couple of hours. I had one with two motors running to make sure it could handle the pressure.
worked fine I'm glad to say. :)
I'm actually building them for my valve amp and wanted something small and tidy. But they will work the motors just as well, in fact they have been :ddb:
Low part count, easy circuit as most of it is in the chip and even that only has 3 connections.
Bits you have as follows....
one rectifier, two caps, one transformer
Bits you don't have
one 1k lin pot, one chip LM1084 rated at 5 amps,
You will need something to mount it on and some wire, which you may have...
There really is nothing to it if you are interested I can give more details. It will run 12 & 24V motors.
Mine need to run at 10A each for the valves, so I'm sticking a 2N3055 on the end, well a pair of them in fact. You can do the same, it's simple enough and would help the LM1084 to run cool instead of hot. But it can take it. Besides it has it's own build in protecting circuit so you can't damage it anyway.
If that all sounds too much, don't worry I can show you step by step if need be, I can always build another one and do a post a day for each component with pictures :lol:
When you have done it once you'll find all sorts of things you want to power and make some more...... :ddb: :ddb: :ddb:
