    Not really Robert, 100 is a tad more realistic than 000

    ah gotcha i thought maybe your perverse sense of humour had created a thing .


    pre plate acquisition i had thought up a variety of plates ...eg...

    M50VSA......MEDUSA

    M121NLN....M12 INLINE.

    G18RGN.....GORGON

    S78 7WLV.....STRAIGHT TWELVE

    MED 115A...MEDUSA

    but decided i wanted dateless and a lot cheaper than those would be !


    meanwhile ..



    today i am working on the steering boss , i have carved the knocker to a nicer shape ,and now about to ruin it all with air bubbles in my first ever resin pouring ....




    i fitted the replacement coil a couple of days ago and it's firing on all cylinders again , i turned down the gas pressure from 24 to 17 so it would open the front injectors on statrup as well ....in this cold air it was having a problem .





    regards

    well , this week i have mostly been eating turkey.


    in other news , once again god has vomited on my duvet ,...



    did the plastic surgery on the brass face ,took away the black bits ...





    supported it in the mould by its very own eyeballs ..






    and mixed the resin ,used it all to be sure i had the right ratio , and poured it in ..






    left it 24 hours ,and it did not set ...even a little bit , still just as runny as when i poured it in .


    my conclusion is , i did not mix it up with enough vigour , i used a 4mm plastic rod to avoid bubbles, which worked very well except it was not making enough agitation to mix , oh well , you live and learn ...interestingly the rest of the mix i mixed furiously to se how much bubblage there would be , and it was very cloudy ,but next day it had set and was clear .



    having no idea how to rescue my mould and get the super goopy sticky stuff off ,i followed a back up plan , i machined out the clear rover boss ..







    popped in the old banjo steering wheel ring and emblem..







    and i can paint the back black or summat tomorrow.




    next i attacked a 10" crack that appeared in the tail after it slammed shut a few times ... i p40'd it , then sanded and painted , with some halfords chrome to see how it would look..







    i yike it !!!


    NEXT ...YES, THERes more ..


    i have always been bothered by the bonnet join, it was really fretting my trabant .. so i made an experimental strap in a quick spare hour ..
















    i much prefer it , looks more cohesive ..oh yes .






    tomorrow i test drive with my new gas pressure and see how out of wack it is .



    regards
    robert

    Looks much better.
    For the resin, you could just carefully pour out the non set stuff and then straight away mix up a new batch & pour it in.

    I shared your botheration with the bonnet join, that looks much better, tapering the strap was counter intuitive as usual and works well..

    Thanks Mark , re treacle gloop from hell , my concern is , if i pour it out , and what is left on the mould is still runny , then if i then mix up a new batch and pour it in on top will the runny stuff still there congeal and de stickyfy , or will it stay as it is and then ,when i try to remove the top solid bit, it comes out of the mould with the bit that really matters , the curved face we can see when mounted ,all iregular and manky .i am a newby !

    thanks Bernard , yes i agree ... i had no intention to do anything about it when i woke up yesterday , but i was so buoyed by my chromey tail , i pottered around... found a bit of old thin ally , cut it out with the metal snips , and in a quick hour it was done , and makes a huge difference.

    if it won't affect the mould i'd try washing the gloop out with cellulose thinners and a paintbrush mate.
    neil.
    need a job done on your project? i may be able to help.

    Robert, as long as you can pour out most of it then the hardener in the new mix should set the runny stuff ok.

    Ref cleaning it with thinners - don't! it will make a big mess as it only partially dissolves resin - if you have some acetone then that will clean it out nicely and should not affect anything.

    Second on giving her an acetone bath, mix the new batch up with vigour, pour into the mould and place the whole shabang on top of a speaker and play some funky music whiteboy. Any bubbles will be driven to the surface and away from the racket.

    WELL.

    Sunday dawned bright and clea........ok ok ...it didn't .

    It dawned grey and glowering ,like a sullen teenager in a power cut with no cell signal...6c and 8 mph wind , MUST be time to go to the bicester scramble then !

    A 30 mile drive in a car with no roof ,windscreen ,... i am not sure v realised how cold it would be , with 60 mph wind that worked out to around -10c in yer face .

    What we learnt mostly was how low you can get in a car with a sofa for a seat ............pretty damned low !


    We jumped in ,and , after i had thrown out all the Harrodsish picnic basket v had tried to load us down with , (channeling her inner martha stuart ) we romped off into the glum .

    Car felt a bit rumbly and was running very rich , but i knew once warm it would smooth out. The roads were wet ,and v slippy , i had pumped up the fronts to 33 psi to see how it felt and the answer was ,it felt like i was on ice , i was therefore not sure if it was the slippy rds or the high pressure tyres that was giving me ZERO feedback ..But i was all like ........whatevahhh.

    We carried on for about 5 miles into the stark greynosity before it decided to let me know it had only been running on one engine .


    This problem i have with the front majic jet injectors not working for a while still remains it would appear ,i thought i had fixed it by dropping gas pressure to 17 from 24 , but no .

    In this instance i was doing around 50 mph on a slight right hand turn when the recalcitrant ENGINE NO 1 ,decided to join the party .

    Instantly the back of the car made a bid for freedom ,like a christian spotting an open gate at the Colosseum ,and i had to apply a little opp lock and back off toot suite .. all was well however and we had both engines for the rest of the day .



    now the old girl had warmed up ,and was chiming in on all 12 , it was a delicate drive on the slippery twisties to bicester , with no drama , just us tucked down as low as we could go ,v thoroughly enjoyed watching the faces of passing drivers and pedestrians as we drove by ..sometimes waving and then whipping her hand back in as she realized it was even colder out of the car body .

    Got there around 10.30 , and the bloke said "you want to park in the technical centre to show the car off ". i said ...er....ok ?


    They directed me to a lot of people milling around , and i threaded my 9ft bonnet through , parked in a row of cars and went to find out where i should be .

    Found out, and came back the car , or where i thought it was , since now there was a huge crowd around it ,v was very excited by this , i sang froided her ,told her it's normal , but she was not prepared for the medusa effect AT ALL... most fun.


    Fired up and trickled through a little tunnel into a central area , may have had my foot slip onto the throttle in the tunnel a bit . Parked up and chatted , wandered about chatted , had a very nice chap come and video interview me , who at the end remarked i was "live to "the middle east" "......so that probably spoiled the cous-cous and dates of a few million desert people #innapropriate.


    Next up was time to naff of , we had become even colder standing around in the windy airfield from planet/moon Titan, and we thought we were going to get even colder on the way home , it had rained a little on the way , so at least it was a little dryer , the weather the equivalent of said teenager having found out no one else had a signal either .

    Car fired up well , v rich again but as she warms up it leans off to normal , , and we bumbled out of the site... interestingly , inside the car we WARMED UP ! , with the 7.6 litre foot warmer helping a lot .


    Home again with no drama .


    Indoors for open fire ,hot baths ,and Sunday evening draped over the furniture under duvets ... nice end to a brilliant day of fun .



    here are a few pics ..













    its in there somewhere...











    regards
    robert



    Oh ! i forgot to add ...

    with my whole resin debacle , i hod nothing to stick on the hole , so v said she would do me a quick fill in .


    i lathed out the clear boss i had ..







    that lets me put in the M for medusa in there ..







    then v tried a few designs ..






    and painstakingly reverse panted a design on the back of the perpex , that i then coated with black gloss..












    she used bits of a christmas tree bird decoration for the twinkly bits , and was apologetic that it was not as good as it could be because it was rushed and had to be done in a afternoon so it was on the car for the show .... i told her to SHUT UP ,and i love it .




    regards
    robert (again)
