You are intitled to fel that £300 for the screen frame is a lot. In real terms it is.
However having the original panels made good enough to mould from in the first place.
Having to then have a mould made in two parts (so 4 moulds in total) to get copies out of.
Getting the first copies out and having to modify them to fit to a standard Beetle.
Having the original (first mould) re-jigged.
Getting another copy made and trial fiiting the 2cnd copies.
Modifying the re-jigged moulds to allow for steel re-inforcment to be fitted inside the GRP winscreen frame.
And final getting a finsihed article out..
I think that considering the amount of work that went into getting a usuable product from scrap panels.. £300 is a fair price to pay.
Because of the time involved in this process, around 300 hours in total which were paid to a specialist to do I have no qualms about asking that price. Because I know that the whole process took about 9 months and cost over £2,000 just to get the single panel that I wanted.
To produce the two halves of the screen fram is time consuming and all done by hand. each one will take about 2 days to lay up and finsih off.
You take a stab at the maths and see if i'm over charging for the item I've offered....
I'll be interested to hear your assesmant of the two methods of production, The screen frame and the overriders.
