Another Allison 6 refurb thread!

Having tried one of the new tweeters for size it seems a bit of fettling will be needed. The original holes with the threaded liners slightly fowl the holes on the tweeters so I have removed the liners. The new tweeters have a smaller face plate and do not leave much wood to screw in to. I will fill the recess of the original tweeter and will use filler to make the hole smaller.

Don't screw - glue drivers in with Bison Kit, then no screw hole problem. 3rd time of saying

I intended using bison on the bass driver but didn't know if it would set hard enough to support the tweeter. If so then happy days! I may still need to modify the area around the tweeter anyway.

Just leave 24 hours on its back for the glue to go completely off.

Bison kit has been ordered. Doc how thick should I apply the glue for the steel plates?

[Dr Bunsen Honeydew]

As thick as you want, you must have used glue before. Honestly trust your own judgement and learn.

A good bond can be achieved with probably less than you'd first imagine. If you're applying by tube, you can 'zig zag' it fairly lightly on both surfaces, I've been giving it 15-20 mins to go tacky before bonding the two surfaces with a tap. This is with 8mm plate.

The difference the plating makes is staggering. They sound just as you'd dream something so brutally heavy and solid would. Effortlessly deep, smooth and clean.

The weight of your speakers must be immense with 8mm plate!!! I'm using 5mm plate in mine. I decided to go for the 650ml tin of the bison so will be applying by brush. I'm really enjoying the process of this project and it is making me more eager to build a set of cubes from scratch.
