Re: Building an IB

(Even though Rodny's joints are almost invisible)

Rodny

Your fabrication skills are truly impressive!

What is the grey material you have stretched over the baffle (prior to your GRP work) which looks rather like a blanket?

Which kind of adhesive did you use to attach it to the baffle?

Re: Building an IB

I think what Darren and I were seeing is the front part... not the actual part the drivers mount too. However, that part will be connected to the front. I'm sure Rodny has already thought of a way to attach it securely so that there will be no resonating issues.

Rodny has done some amazing installs in cars (including mine), trucks, boats (serious boats) and continues to amaze me with his home.

I betcha that material is trunk liner.

Sorry guys!

I going to predrill the holes on the two pieces of 3/4 MDF and plexi that way I can put the screws from the back all the way to the front piece, you wont be able to see the screws from the front, an between the wood, plexi, wood it will be some high density foam tape (weatherstrip) this way nothing will rattle.

The material the I used to wrap it is good old fleece.

Sorry Sonnie is not trunk liner, I used the fleece because is thicker and stretch really good, sometimes I use t shirt material when building a small piece.

There is no glue holding the material, when you use glue and apply fiberglass resin it will come apart, I used staples.

Quote:
Your handy work is impressive... will you paint the fiberglass?
It will be painted black and then clear coated

Thanks again guys!!!!

Re: Building an IB

HOw stiff (read: resilient) does the stretched fleece wind up when it is resin'ed up?, tough enough to take a bit of poking at?

poking it with what?
You'll be surprise how strong it is after drys, you can always put Fiberglas mat from the back side to make it even stronger.
This box here, http://www.putfile.com/rodny68/images/32053 the back is fiberglas mat and the front is fleece.
Sometimes I used trunk liner(thin carpet) never have any problems. You can look at my pics and see the fiberglas work.
