I had pods on my 34s and never noticed before, but the actual hole on the rubber grommet on the pods is quite a bit smaller than than VM 34 bell mouth. Seems a bitbsillynto cover the bellmouth with the pod grommet, so, I decided to ditch the pods and make a couple of pancake filters.
I did try fabricating one from sheet aluminium but found punching the centre hole out to make a fitment tube was simply too much of a stretch for the aluminium. So, I bought a 100mm round slab of aluminium, cut it in half and turned it up on the lathe.
I've made the mounting hole in the filter 0.10mm smaller than the bellmouth for a push fit. I was going to slit the fitting hole and run a thread 4mm thread through sideways to tighten the filter on the bell mouth, but am wondering if the push fit would be sufficient??? Alternatively, I could put grub screws through the filter to tighten onto the bel mouth, but again wondering if the 0.10mm push fit would be sufficient.
The back,ofbthebfilterbwill be beaten up from sheet aluminium.
