Homemade Soldering Iron Questions

[TorqueRanger]

I am using right now a Hakko 939 and has anyone every built a soldering station that is equal to JBC or METCAL

You will not reproduce the hand piece or the soldering tips unless you have access to a well stocked machine shop and excellent fabrication skills, but there is no reason to think you couldn't reproduce a compatible base station and controls. I seem to recall Mike looked into that at some point...?

Well my Idea was to use a Hakko 907 handle  but build the heating electronics setup like the JBC ..

The key functional element of those good soldering stations is that they have a temperature sensing element and a heating element very close to the tip of the iron, a low thermal mass, and a very fast temperature control loop with plenty of power behind it to hold the temperature steady.

Lesser irons have a big lump of copper in the tip to hold heat and compensate for a slower temperature control loop. It takes them longer to heat up and longer to recover if you suck heat out of the tip.

In contrast the higher quality irons make a virtue of not having a big lump of copper in the tip. Instead, as soon as you draw heat the drop in temperature is noticed and the iron instantly ramps up the heat supply to keep the temperature constant.

There is a 14 page thread about a DIY Metcal rf supply

If you search the web you will find an open source soldering iron controller for conventional 24vac heater + thermocouple type irons.

Yeah I have been watching it some what But really looking for something JBC with out all the extra's like a Hakko 888 Basic...

Here is what I would love to make but use a hakko 907 iron instead

Wheredoya get that handle head by itself and whatsit cost? I can easily build a MCU circuit with a thermocouple amp and power supply and a LED readout and pot to adj etc. for this powerful pencil. But what arrpox. cost of the handle and changeable tips?

[Rerouter]

google "soldering pencil" plenty should turn up,

for something more specific in Sydney Australia, there is a large distrubuter known as "WES Components" and they have all sorts of replacement parts and pencils, and will give retail prices over the phone,

Assuming you mean JBC, take a look at the following (US location, but they sell internationally and have good pricing).
