Hi Gentles

New Dyna after all, from Germany. Already in place, and old one wainting for better opportunity to be rebuild.

A pic to enthusiasts.

Cheers

PS: Bought also a Voltage regulator, so can get juice from alternator and Dyna.

Hi Gentles

Unfortunately the 50% heir selled to a scrap buyer all bulk iron (6 tons@ 0,18/kg ~ 1100), dragging the other 7 to the deal.

Lets see if the scrapper wants to sell it at reasonable price, otherwise its the 2nd (1st the Lister CD) lost this year (and 1L WD40). Thamn!

Hi Gentles

there's nothing wrong that can't get worse! (people sayings)

New armature arrived, and... Its only 60mm diameter (original 68mm), longer than original, and commutater thiner and less segments. THAMN!! (second disaster)

I think i'll have to send it to Pakistan to get fixed. (where craftmen, masters is the word, still exist)

DOUBLE DAMN!!

More money to south!

Hi Bob

Thanks for your support, but...Im in the other side of Atlantic Ocean.

Customs here (and there too) has a tiny hole net to catch and tax from abroad stuff, and are 24/7 aiming to shot at anything that cross the ocean.

Take a look at the price my keystock arrived from USA (https://listerengine.com/smf/index.php?topic=8320.msg102563#msg102563)

Postage is very expensive! labour is expensive.

Already ordered new rotor, and voltage regualtor.

Hi Gentles

Looking around I find a shop that can make hairpin coils, but.... (allways a but) they dont have 3*1mm flat copper wire, they need at least one old hairpin sample (all busted now!) to make the jig... and if (onother thamn word) I find correct copper wire they will charge... 125+vat for labour.

In other hand found this retailer in Germany (https://www.simon-auto-shop.de/epages/Simon-Auto-Anlasser-Lichtmaschinen.sf/en_GB/?ObjectPath=/Shops/Simon-Auto-Anlasser-Lichtmaschinen/Products/AN9098), with new armature, and costs 59,5+P&P. So Im gone order a new one!

And found at same retailer voltage regulator (https://www.simon-auto-shop.de/epages/Simon-Auto-Anlasser-Lichtmaschinen.sf/en_GB/?ObjectPath=/Shops/Simon-Auto-Anlasser-Lichtmaschinen/Products/RE1065N).

Will see how to manage it.

Hi Gentles, Bob and Ade V

This was a scheduled event. Of course "someone" has to pay domain name, and make backups, maintenance, grant new members.... you name it!

A few days ago I print to pdf my 2 threads, just in case... it crossed my mind the disaster it happened to Peter Forbes (RIP) site. Countless houres and years of collected info desapear by night!

In the same way all info of Guru Butch gone away - just because!

For what it worth, my threads have some junk replys in order to never raise to the WOK (its dangerous to be in WOK!), because im one more guy that make palmatory stupid things, and is trying to prove that the square wheel will spin same way as round.

Bob & Ade, dont let this thing go down. There is too much usefull info to let it go away.

Cheers

And now I have to rebuild it all! All windings.

Take all coils from rotor, search for new ones (or someone who make them), counting turns, make a jig to wind new ones, etc, etc

Hi Gentles

Remember I had a restoration aside Lister 12/2 - a Penta 6A, 1971? And the dynastarter was refurbished? (see here: https://listerengine.com/smf/index.php?topic=8320.msg104124#msg104124)

After put it on the engine, all working good, dynastarter firing the engine nicely... after tuning idle rpm, and max rpm, it never started again with the dynastarter.

Tried another battery to see if the issue was from there.... and nothing. Thamn, maybe the dyna have some issue, I think.

All disassembled and... thamn, dynastarter is busted. Worst, rotor had windings destroid. Thamn!

Lesson learned: a few meters of nylon twine in the front copper coils had prevent the disaster. (Think was the full throttle that put centrifugal force in coils, and they just open to the side, and destroy all thing)

A few pics to show the disaster...

Hi Gentles

As far as I know that power factor is relatively to the magnetic and heat losses. Wont you all agree?
