Sump baffle plate thickness?

1. Going to make a alloy zx9 baffle plate but how thick should it be?

2. Where can i get a piece of alloy sheet the thickness above measuring 12 inches by 12 inches? Ie places like B&Q ect?

3. I need to shortern my pickup. Do you just cut an inch out of the stem and just stick it back together edge to edge or do i have to sleave it in?

I think you are probably best making it in Stainless Steel...

I think the Ali ones can fracture.

I've used 1mm ally. (I think it may be 0.9mm to be honest) but I haven't shortened the sump, gonna try and get away with it. IRC from searching other threads yes you just cut as shown and some people have used a collar to help stick the pick up back together.

Hi Matt

As just mentioned in my u2u reply, this is roughly how my uncle used to do them


ZX9 Pickup chop
ZX9 Pickup chop


Basically he'd cut the pickup off where it goes from tube to cone, then chopped again further up to get the desired length. He then machined a shoulder on the tube segment and reamed out the conical bit slightly until the tube segment would just about slide/snap into the conical section. He then glued them together with superglue I think, or possibly Epoxy resin (Araldite).

As to the thickness of the baffle plate, this is what happened to my original fireblade baffle:

Blade Baffle fatigue cracked

Im not sure what thickness it was but its the one Westfield / STM / Kit Car Workshop used to supply, I think it was about 1.5mm thick. With that in mind I'd go as thick as you can get away with, or preferably as others have mentioned use thin stainless steel if poss.

cheers
Chris

How thin in stainless are you talking about then?

Steel doesn't suffer from fatigue cracking like aluminmum so it only needs to be thick enough to support its own weight really, so 1mm or so at a guess

The above was installed for about 3 years, around 20 trackdays and maybe 4-5k road miles, and to be fair Ive not seen another one go quite like that so its possible that one was a bad batch of metal. If I was fitting another though I'd certainly drop the sump on each oil change to check it was still intact, but probably would look to get a stronger one to avoid the worry.
