Well i finally started building my S.D.M. using the schottel drives that have sat in the box for too long .
And after mounting the units it came time to re-assemble the drives , the last thing to fit on them is the circlip on the shaft top , first one went on ok but the second one went somewhere else . It was just about in place , one little flick with the flat screwdriver and all would be sorted, but no the little bleeder went awol. So where do i get spares from , i don't realy want to try Graupner as they may be expensive , any ideas ?? .

Daz....any ball bearing distributor will be able to source or supply a replacement circlip - you may need to remove the first installed circlip to measure it accurately
In OZ we use "ANDERTON" brand [UK manufactured] circlips .....try a magnet on the circlip...I suspect it will be non-magnetic & if so is an austinetic 300 series stainless steel = non rusting
ANDERTON use a "KSF" suffix to note non magnetic ....you may well find that an original from Graupner as a replacement will be cost competitive....... O0 - Derek

Hi Daz you could get one from my garage, I have a jar full ofall different sizes.
Give me a ring and I will call round, jar in hand.

cheers Andy , i may take you up on that offer . I have to get the brush out this week and give the floor the once over and i may find it .
the problem is i can't see the floor for rubish , i did think about replacing the clip and drilling out for a split pin (i got a box full of them) but the shaft is probably hardened steel.

Well i finally got round to cleaning the workshop floor and almost gave up finding the clip , when i spotted it poking out from between the floor boards .
Cant understand how it got there as the area was covered with a piece of carpet. So i have now fitted it where it belongs , sorted :-)).
The build continues i now have to save up for the servos ££-.

not as yet , but the hull will be much like the SDM tug i built using two fixed props

which i still have to work on .
All i have done on the new build is the base for the deck , a box for the hull and a alloy/plastic (information sign) base . The hull sides will be pollystyreen which will be easier and make it totally unsinkable , if it's like the other one it will be i have stood on that one and she still wont stay down {-) .
