Type 4 bulkhead

Post by Chrispy » Sun Mar 15, 2020 3:51 pm

Spent the week making an aluminium bulkhead to try and reduce noise and draughts in the cabin.

Got to test it today and seems to help at lower speeds for noise and better all speeds for draughts.

Thanks to Alan for sound deadening material and Mark Gallagher for guidance. Now got to replace indicator relay that went awol during test!

Excellent job Chrispy.
How did you define the size? Did you use CAD [Cardboard Aided Design]?

BTW: I don't know if you noticed the nap on the Wilton is not pointing towards Axminster. Just sayin!

Hi Richard,

In my previous life, before retirement, I could have done as I was an Autocad techie!

It was the Blue Peter approach with glued pointers defining the inside shape of bonnet. This then transferred to plywood and much on/off fitting to establish size/height. Then ply template to 4mm ally which I cut with a powered jigsaw. It was a close enough fit to allow the foam edging to fill in any gaps.

Had I still been at work could have borrowed a 3d scanner and done the job in a day, but where's the fun in that?
