Drive alignment
I have some problematic 1541's which I have tested on speed and alignment, with various old tools. Drive-speed was easy to fix but alignment is a bitch to control and adjust! I'm new in the area of fixing drives, so I need some experienced advise on tools to use and info on the techniques :)
Request: Tools (which you use with success) and info/text on how to fix the alignment!
Thanks! |

Yes, the are trustworthy. I bought my alignment disk from them. But it seems that since this thread started and enthusiasm spread around this alignment disk, these guys rose the prize. It was 12.xx euros when I bought it, now it's 17.xx euros. They know how to make good deals!!

ready. it's not so bad, the euro is worth more than the £ for a start..
I wanted to buy some soft synths from europe, but due to the £ being not so great exchange rate wise I won't bother till its a bit better. |

No, the pound isn't worth less than the euro.
It's the dollar that is lower. |

mace.. 75p / £0.75 = 1 euro...
go back a while £1.20 / £1.30 = 1 euro
the US dollar is normally half a UK £1.. always has been , or very near that mark £1 = $2 for a LONG time, for like 10+ years as far as I can remember
it's messed up now, it's to put people off buying European imports (and probably to stop the people coming in sending money home (not uk) ) , instead of spending it in the UK.
Some of the soft synths I want are dutch etc and can only be bought from the person direct / via their website. So because of the exchange rate I will put off buying them from their country.
I wonder if I can still get my dutch guilders changed from x95? hehe |

dear all,
I recently bought a 1541-II and it had some problems when running demos. For example Edge of Disgrace crashed some times. So I ran the Free Spirit Disk. I checked the head stop position and it gave it was in a bad condition, the head stopped at track 1.
Reading the manual given with the disk, the stop should be just before track 1, showing track 0 on the screen, so let's say track 0.9999999
Then I adjusted a bit the head stop mechanism, so that the program would give me positive result, shwoing track 0 after bump test.
Finally I ran Edge of Disgrace again several times and it worked fine.
Now, this is the second drive I manage to fix just by using the head stop block. Reading around about misalignament, I read that this occurs usually because the shaft of the stepper motor is made of steel but the flywheel driving the head is aluminum. Due to heat and mechanical solicitation (expecially when bumping at track 0) the flywheel slips from the shaft, causing misalignament.
Now, according to my experience, moving the head stop backwards (towards the rear of the 1541), can restore the alignament, re-gaining the track lost during the slipping of the flywheel.
Is there any drawback about this method? It seems so simple to me that I suspect there's something majorly wrong that I am missing.
Ready. |
