Help with HUDY

[Mark Huber]

So, to make a long story 'relatively' short. I bought a HUDY a couple of years ago. It worked for 15 minutes and then the motor went dead. I traded it to Ken with the warning that the motor was dead. Ken confirmed that the motor was indeed dead. Being the electronics wizard that he is, he put in a new motor and now has a working HUDY. I vowed never to buy another HUDY.

BUT... attempting to true tires by holding the car against sandpaper on a piece of track has not worked for me. AT ALL.  Witness:  check the GPD2013 thread and see how my  car is doing.

So, I relented and ordered another HUDY from Professor Motor. It arrived a few minutes ago.   Given the price, the motor better last longer than 15 minutes this time.



Now, I am a very visual person and the instructions that came with the HUDY are ****. I'm sure it is a fine machine.. it had better be.. but I need a video to watch... HUDY for Dummies.   So I found one...

But this is HUDY für dumme Leute.  What is this fellow doing besides adjusting the little knob back and forth? And fiddling with the machine for 12 minutes, part of the time when the truer isn't even in the picture frame! Gott in Himmel!

Taffy,  please watch this and send me the English translation,  Mein Deutsch ist nicht so gut, und Ich kann nicht alles vertstehen.  Danke schön.

So I tried again,

This one is in English (or at least something that passes for English)...

It was amusing listening to this fellow and trying to guess what he is saying, but he's using a different machine. He's also truing something he calls toyers, so this probably isn't all that helpful.

I speak American English and I can understand some versions spoken in Canada and the UK (excluding Cockney and anybody from Scotland excepted).     I did find a video made in Ireland but every other word sounded like shide (sic?) or something that rhymes with 'lookin'" (often used together) so I decided not to add the link for that demo.

HELP!


EDIT: Wait a moment.. here is part two.. what is with that goop? is it legal?

Mark, I have not viewed the first video, but the Hudy has an adjustment that allows up to 1.5 degrees of camber to be set when truing tires. I suspect he is setting this adjustment, and it is worthwhile checking prior to truing. Most of the Hudys I have looked at were set at 0 from the factory, but you never know. Grinding a camber into the tire is generally done on sponge tires, but has been done on rubber/urethane.

The goop is UHU superglue....spread on the tire, then trued, to reduce front tire friction.......some clubs allow this, some don't. Our club does not permit this as after a time little bits of dried superglue fall off onto the track. As well the tire surface ends up being somewhat shiny. My strong preference (especially for our cars) is to ban this practice.

Cheers
Chris

PS If your Hudy motor ever craps out, most $20 RC motors will bolt right in.

The motor is dead.. I wonder when HUDY shipped these pieces of @$%% to the US... ten years ago?


Fortunately Professor Motor is good about stuff like this, but what a royal pain in the ......

Look in side! Dead again? Yer kiddin mate!

I don't learn from my mistakes, but I'll learn from your's...no Hudys for me.

Well now it sounds like actual advice...certainly not what I meant...

No I get it.. we probably shouldn't cuss in Irish/English... By the way, why wasn't "The Commitments" subtitled in English?

The folks at Professor Motor were great; they are FedExing a replacement but this time they will test it before shipping!

I have to apologize, Mark, but in the last weeks I only concentrated to the GPd2013-thread and so I didn´t read this until today...

But here is HELP!

First: Chris is right, if he tells you, that with the Hudy you can adjust the camber. But this isn´t shown in the video!
I have another truing machine, so I cannot explain how this is done....

2nd: in the video the guy tells, that he is working the machine with 4.6 Volt DIRECT CURRENT! The original Hudy motor doesn´t work with alternating current. Might this be a reason for your dead motors?

Now the video:

- 02:02        the guy explains, that the shiny surface of the tyre gets mat as the effect of the truing
- 03:00        he explains, that if the tyre is trued to fast, it becomes to hot with bad effect on the grip, (to move the right, bigger knob slowly and step by step avoids an overheating of the tyre)
03:34-03:50 he shows, that as a result of the proper truing the tyre is uniformly mat.
04:00-04:30 shows the adjustment of the left smaller knob/screw = it is a locking screw to get repeatable results / widths for two or more tyres
04:50-06:22 shows a shape tool to round the edges between the tyre wall and the tread. He says, he has got it in the same slotshop, where he has bought the Hudy ( which shop? He doesn´t tell it...)
06:30-07:22 unsuccessfull attempt to draw, what the shape-tool is doing to the tyre....
07:50-09:25 he shows the finetuning of the tyre with 10 different sandpapers, beginning a grit size of 180 up to 3000 (this means the grit sizes of ISO/Fepa Grit Designation, you can find a comparison here in Wikipedia)
09:30:09:55 he shows the polishing with 4000 mesh
-10:50         he compares the trued tyre with a new tyre
11:12-11:55 shows the mounting of the 2nd tyre to the machine
- end:         shows truing of the 2nd tyre

I hope, this may help you...
