Ancient History... for anyone interested :)

RELinquished circa 2003

Built with this homemade jig instead of a £1500 jobby :













Looking through my old notes I apparently used a DIY 30mm nailgun to lightly pin the panels in place before finally locking the biscuit joints in place with a couple of screws. So I might have to change that post in another thread about DIY nail guns only being suitable for rabbit hutches

Please note the 4 screws on the front panel

Re: Ancient History... for anyone interested :)

Whatever happened to this then? Do you still have it, or any finished pics? This is doing my head in not being able to start mine yet. I did pick up my speaker binding posts from Maplin yesterday though, so I'm kinda doing bits here and there

Do tell us more.

Do you have a bigger image of this jig of yours?

The amp looks decent with a nice big toroidal transformer.

Re: Ancient History... for anyone interested :)

BSB12 and BSB100 or 200, so IIRC a similar to a REL Q100(e).

Re: Ancient History... for anyone interested :)

Spot on it's the BK 100 amp panel and it was a REL Q100e clone. A number of us who built one later upgraded the driver and I later moved it and the amp panel into my current sonotube that was built by Mat-Moo. The box was dressed in a speaker fabric cover with a slab of black granite on top.
The jig was designed to run a circular saw in to enable keeping a straight cut easily. Not sure if I can find a larger pic but I'll look.

Your point?

I just feel safer having used 114 (in total on the whole box) and yes I did count them.

Re: Ancient History... for anyone interested :)

Studies show that using 115 screws is significantly more effective as 114 doesnt reach the exact threshold of strength required for optimum fastening on a box of that size using 1" MDF. Sorry to tell you this, but your going to have to start again.

I thought you might spot that comment I was illustrating a different construction technique Russell, using glue and biscuits with screws in a supportive role, But I certainly wasn't trying to imply it was any better than yours

Re: Ancient History... for anyone interested :)

Ideally we need a graph to show the tipping point where 114 screws is totally inadequate and 115 more than you will ever need.

Mmm. Biscuits! Chocolate digestives, anybody?

Re: Ancient History... for anyone interested :)

Screws is always a debate with subwoofer building.

You certinaly can go too far with screws and weaken the wood connection though a reduction of surface area for the glue to use and a splitting of the wood in various places.

Also a badly driven in screw can pull the wood join apart and a correctly driven in screw can keep things tight.

Re: Ancient History... for anyone interested :)

I disagree... Over 250 in mine and I have not split the wood once. All piloted and is solid as a rock. I made pilot holes in the wood I was screwing in to. No splits.

cheers

I'm sure there is a link somewhere showing this, and the exact torque setting required on each screw to hit this point exactly. Go to far and you shorten the lifespan of the cabinet material
