Roaster blues

Postby motoman » Sat Nov 11, 2017 9:02 am

Yesterday I was happily roasting away, then I was not so happy. The drum slowed to a very slow jerky rotation, the heat shot up and disaster imminent. As the roast was nearly half way through, I attempted to control it by lowering the heat, due to the slow speed the temperature seesawed up and down but I managed to finish with a very good looking roast. This morning I tested it, there is that marshmallow blandness you get from using the beans too soon, I am hoping for better tomorrow.
The good new is that I contacted Mr Li in Taiwan and he is sending me a new motor by air mail.
I have stripped the machine down and I am very impressed by the skill that goes into building a custom roaster. The stainless steel welds are very neat, there are lots of screws and nuts holding it together and the whole unit strips down completely. I was able to clean it up in the washing up bowl in the kitchen.

That's a pain Pete, glad you have it semi-sorted though. It's a lovely roaster you have there. Let's hope the motor arrives quickly.

These things just always go right on top of Christmas with only a little time to get them sorted. Both our major machine failures have been right on the festive season and kept us

How are you keeping old friend?

The roast yesterday looked good, wish I could say the same about the taste. Drinkable just! with a slightly bitter aftertaste. The good news it that the new 72rpm motor is coming by air mail, more good news it will only cost £27 including postage. Wouldn't it be nice if urgent items could be emailed. I will part reassemble the Huky later today, most parts will go together without a hitch. My biggest job will be fitting the new motor in to its housing when it arrives, the tiny nuts inside the motor housing were a swine to remove, getting them to hold still when I fit the Allen screws through the back will take time and bad language. Working in a confined space and the joys of arthritis are an interesting combination, my hope is pinned on holding the 4 tiny nuts that secure the motor, blutacked on the end of a pencil, while I line up the motor with the holes in the housing at the same time holding the 5mm Allen key.......................... I need alcohol.

Hi Cakey, I'm almost fine, I gets lots of exercise walking away from crowded doctors waiting rooms, I don't have enough time left at 83 to wait hours for a medic to say 'your doing fine for your age Mr Green'. boring updates on kidney status and prostate prognosis show I have a reasonable chance of surviving well past my alloted span. That suits me OK. Otherwise, I can always give up coffee and become just another complaining old fart. Just remember old friend, if a doctor tells you to give up muffins, you can always change your doctor.

Updates as they happen........................

Well £27 sounds good indeed as long as it doesn't take ages to arrive.

You just keep on drinking the coffee and complain all you want, you've earned the right. I reckon you might outlast me. I'm old and broken but they'll never take my muffins! Carry on roasting those beans and you'll not go far wrong. Ooh matron! :shock: Sorry, ignore that, I should never start a sentence with 'Carry on' :oops:

The plot thickens....

New motor arrived, after a lot of fiddling, curses, sweat and blood... BLOOD!... Where am I... Ah OK now, can carry on. Tested the motor and after a couple of groans it started and I ran it for 10 minutes before re building the roaster, lots of awkward sharp edges. hence the blood. All together again so plug it in, turn on the gas and wait for it to heat up.............. Did I ever tell you about the time I fell, I am sure I was pushed, out of a helicopter in Borneo? No!!! I will bravely carry on. The drum started to stutter and slowly, jerkily began to revolve, it was as if I had put the wrong motor back. Nope, old motor, with bits of solder on the terminal, on the table. I think it is heading towards another strip down, the drum revolved OK when I turned it by hand, not easy as without the motor it is only supported by the front bearing. I will take the bearings out and replace if necessary. I will also count the motor revolutions and hope it is 72 rpm. I will also check the Huky forums to see if others are having problems.

More.... when I stop crying......................

Isn't it a lovely day, rain, cold snow forecast with high winds. I don't care, I am roasting again. After my second strip down I tested the drum bearings, no problem, running sweetly. I retested the motor out of the unit and it still stuttered round improving my language skill with words I haven't used since my career in the service of Her Majesty.
The wiring to the new motor was good, I even used a powerful glass to check the solder joints. I turned my attention to the switch, this was untouched as I only had to solder the leads to the motor. I noticed that the negative lead solder was not up to Mr Li's usual standard, the lead barely touched the terminal, I unsoldered and reattached it, plugged in and Bingo. Always check the simple stuff first. So with egg on my face I confess to forgetting the basics. The upside is I now have a polished shiny roaster that is even better than before, listen to my advice then do the opposite.

There is nothing worse than all sorts of repair and rebuilding only to have that sinking feeling and nothing. So pleased you sorted it Pete, that was very well spotted. Enjoy your roasting!
