my clamp progress has been slowed by a lot of work related travel. i have been in okinawa for three weeks and shortly after i return i am off to colorado for a week.

i am concerned that the center bore is not running straight on the clamp. with such a long and narrow bore the tool might be pushing off center. i need to quantify this problem and possibly make some design changes before i proceed.

My first test

All mods are as per Okapi´s PDF. Source V+ is 7.97V, 300/100R at Dout, 10nf ERO 1830. Only the crystal oscilator is stock. First impressions are very positive.

Thanks Peter, Algar, Okapi, Audio1st....

BTW I hope Okapi will take orders in a group buy what he mentioned earlier on otherwise I am most certainly interested in your offer...anyway I am interested in your pics of the clamp..

Peter are you using Okapi's clamp at the moment or are you also waiting untill Okapi finds time to help out....

In my opinion, a three leg pulley clamp is better still. Reason behind is the bending stress is well evenly distributed, think can get a cheap one from a local hardware shop. This Three leg gear puller is from China. USD10??

Which -51 builder can help...

I have build a dedicated powersupply 8 Volts and fed it direct to the motor (on the choke position).
I also fed the led with 5 Volts direct (orange and grey wiring)
By doing so I could remove the main board and ps board...

When firing up....the disc started to turn like mad...searching.......and stopped.....and the led whas not lit....

Measuring and checking and everything was okay

Hi Erik,
Lets start with the LED, orange wire is NEGATIVE and the grey wire next to the orange is positive. You will need to add a series resistor as well.

If you have 8 volts and the polarity correct, I can't see why you will have a problem with the transport..

Erik, your LED may not be working because the voltage is to low. The 10k resistor is based on having up to 25v of supply. If you have a separate 5v supply, then 1k is more than enough..
