Annealing, First proper go.

[Alantoo]

Per your advice to me in April, I bought the Sievert 86 Pro torch and 393902 nozzle. That was some good advice Alan, thanks. Very controllable and well focussed flame. It has made the annealing journey a lot easier.

It is nice kit isn't it?

Help! I just counted up, mine must be around 45 years old now!

Done the retest at 6 sec with the blue heat on the shoulder

then out of interest I also use a starline LP case

This is the brass i use the lap is of no interest as it Small primer.
here is the 270 case at 8.? sec the red blush was replaced by a F*8ked case

Thanks for info .

Did you photograph them with the Tempilaq on? You can't tell much from the brass alone, especially in photo.

You can always do a double check with the soap.

The useful thing about having both on hand is that the soap starts to change colour 75˚C (ish) below the 400˚C but doesn't go any "blacker" above it...the Tempilaq doesn't change at all until it hits 400˚C.

You can use soap to work up to 400˚C gradually and the Tempilaq to confirm you have got there...just going in with Tempilaq doesn't give you any clue whether you are going well over 400˚C unecessarily.

Not that taking the necks and shoulders over 400˚C would be a particular problem...provided all the cases were taken to the same point for consistency. A lot of people take them to dull red in dim ambient light (which is nearer 500˚C) with no problem.

Forgot to add pix

As far as I can see from here the tempilaq looks much the same as the 6 second one so no need to go any longer than that...you could even try dialling back from 6 seconds if your control allows, and see what difference half or quarter of second less makes to the Tempilaq.

Can you show us a photo of your complete machine set up for interest?

A few more holes than i'd wish but i had re jig it due to the cheap plastic gear motors from ebay now running on British all metal gears lol also added a rubber pad to stop the case bonce I was getting and spinning the case out of line The mk2 hopper holds over 100 cases so all good for running all the brass I have in batches ,Its a KISS device and thanks to you lot its working ,not posh but hay ho this and the SS roto pin cleaner has kept me bizzy when not at work dealing with the c19 .
Thank you all for your help

Nice one!

I had a brilliant little catalogue of gears and bearings for building such wonderful automata...I will see if I can find it when I take Mum's meal over this evening and whether they are still in operation...may be useful for the future.

Found the little catalogue and I did a quick google evidently they are still in business. Last thing I had from them was a pair of bronze bevel gears for my old Elliot bandsaw I think.

In truth all you need are two wiper motors and ford/ other 12v dash dimmers and a stop watch the motors have the grunt should something get stuck ,the chinky motors I waited weeks for were crap at best the drive gears once I stripped them out were all plastic just dross and unfit to use . A bit of understanding of the end result the rest is easy lol , I did fit 25mm sealed bearings in the face of the cabinet on 8mm shafts and 5mm coupling connectors with end float on the mk1 thinking I would need to take up any play none of which were needed Sometimes over thinking after building bits for aircraft and cars do's not always mean you can build an easy K.i.s.s toy, A bit of woodwork comes in handy pmsl , thank you very much for all your help

 

[paul o']

belts and gears hmmm and one motor , So now were talking reduction gearing belt drives a whole new way of making another toy pmsl .no i'v got to stop lol

An old blacksmith friend from the USA had these wise words for me when he saw some of the stupidly complicated jigs and tools
I had made up....”Always buy the first one!” Meaning you can always do improvements and modifications but there is no need to totally reinvent the wheel!

But where is the fun in that?

As a very young lad, I was requested to make drawings as part of a test for a ball bearing mouse trap !and after the three hrs allotted I had on the tech drawing board this fantastic contraption to basically trap and kill said mouse ? the examiner came back in looked at all our hard work and without saying a word drew a TOMCAT on the blackboard and walked away shacking his head , ball bearing mouse trap ? the Bastard
