okay chaps, i've been busy.
i will probably have to order more plastic but i will wait and see how many of you want upgrade parts for your 2-1b heads.
i have been fiddling around with a spare neck trying to see what problems there might be and to give advice on fitment from what i have found.
please read carefully the points i make. it will make life easier for you.
i have test fitted
every neck into a casting to make sure it fits and the visible portion is okay. there may or may not be some additional trimming required.
it depends on how fussy you are.
measure twice cut once, there are no "spares" if you **** up!
to put a neck into the head casting it needs squashed length ways and the rear part inserted into the head first followed by the front.
take care not to scratch the plastic against the resin of the head. you could put tape on it on the outside to protect it while you fine tune the fitment.
it looks like the neck ring will have to
go on last due to the clear neck having to be squished to fit it inside the head. this is
my advice but its your choice what you do.
as you can see the neck it very flexible
i cut out the hole around the base using a knife attachment on my gas soldering iron, it really was easy doing it this way, the edge was tidied up using a flap wheel pictured.
cut it out to the size i did it, there is some material left to bond the neck ring to the plastic this way.
final fitment at the rear you are trying to get approx 25-28mm in depth as pictured.
again as before the neck pictured below is just hanging in the casting, its not fitted in any way so it is off in some places.
i think i have a solution for the fitting of the neck inside the casting but i will need to try it first and will update you all on my findings.
i also sanded down all the neck rings to the correct height as i thought it might be a bit awkward if you didn't have a belt sander.
hope you like the pics.
forgot to add, where test fitting the metal tape i found it a little tight on the red line pictured below, you risk bending the tape trying to force it in the space, very little needs to be taken away, there is a spare piece of metal tape included so you can use for test fitting etc.
junkyard thread will be up next few days probably. still waiting on stuff to arrive.
