getting an accurate profile
Morning all again
Further to my earlier post on my Mac1 sports screen not fitting my Indy scuttle properly.
It appears it's down to the profile of the bottom of the screen not matching the profile of the scuttle.
So I need to reprofile it to match. Anyone got any clever ideas of how to get an accurate profile off the scuttle top so I can tranfer it to the
bottom of the screen?
Any info on techniques greatly appreciated.
Cheers
Nigel

This, I know how to do. Get a piece of heavy carboard or thin ply/harboard. Stand it on the scuttle at the angle you want the part to sit. Use some
supports to ensure it can't move. Cut the lower edge approxamilty to match. When it's close, use a block of wood or similar as a spacer,
with a pencil held or attached to the top of it. Slide the spacer across the scuttle with the pencil drawing on the template, so that you get the
exact scuttle shape drawn on the template, but with an offset of the spacer thickness. Cut to this line, and test fit. Repeat with a thinner spacer if
necesary

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

Hi Nigel,
How about making a card template and trimming it till it's right the use that to mark out the sports screen?
Use plenty of masking tape on the screen when you cut it to help prevent cracking/scratching.
Any recent build pics on th go?
Cheers
Nick

Cut card to basic shape as fred said then run a marker pen along the panel. It will draw a line about a centimetre above where the panels edge.
Or, stick parcel tape to the panel you want to replicate and lay up GRP onto the tape. It won't stick to the tape but will cure to the required
shape.

How about a thick sheet of cardboard, a spirit level and a pen?
Basically then you can "block it out" onto the cardboard.... Just looking for a description of "blocking" on the internet.
It's bloody easy to do, difficult to describe!!

Yeah, but it was Fred who explained how to do it, you simply said what material to use
