Maybe however, How do you know he didn't just get a copy from elsewhere? Also you are hurting authorized builders in that area as they have to pay to be an authorized builder.

I understand that there are situations that happen, like when you first realize what a small number of these boxes can do. But Bill puts a lot of trust in the way he runs this business, given the value for money, I urge everyone to be on the up and up.

The forwarding of the original email containing the plans to prove ownership?

Well since there's only one authorised builder in the UK, then that shouldn't be too hard to check.

Totally agree here - I'm not suggesting for a moment anything untoward, but where does one draw the line. Is it OK to sell a BFM box after 1 month of use? 6 months?

Anyway, maybe I'll just build the darn thing myself. I have access to a friend's fully kitted workshop and his expertise (and his ultra lightweight ply), but that means getting a "day pass" from SWMBO as he's a fair drive away, whereas when I built the OT12s and WHs they could be nibbled away at in small sessions from home.

Sorry to derail the buiold thread. I'll shut up now.

I'm sure nobody is going to get their knickers in a twist over 1 set of surplus new cabs going on the market. Repeat sets would get jumped on. Sales of used cabs have their own rules.

In any case a plan purchase by the new owner gets them the benefit of the operating instructrions as well as removing any legal issues.

The solution rests in the buyer of the T39, also buying a plan costing a mere $14.95. But as has been said before, this should not be a common practice (to build and then sell for profit).

OTOH, given the equipment he has access to, and the quality of his build, he should give due consideration to becoming a builder himself ...

Thanks for the kind words el, whilst i have no intentions of becmoeing an autorised builder or a joiner full time it is nice to know maybe I could one day if I decided.
These were never built at the start with the intention to sell, looking eariler in the thread you will notice I was never sure why I decided to bulid 8 but I did..... These wont be sold for any profit tho, the time I have invested in these mean short of charging like fk1 or l'acoustics I wont be turning a profit. With only one builder in the UK i would not expect to take buisness from them either, anyhow I'm on a electrical eng. masters at the moment that is taking quite a lot of my time so the sale of these altho 95% finished is still a fair way off.

This pic gives me an idea: T39 in the laundry room. It would blend right in as my washer and dryer look just like that.

I particularly like how you rounded the cover corners. I tried to do mine the same way (albeit with a larger radius), it didn't look so pretty.

Yeah. I'm more than a little curious how that was done. It looks very elegant.

One plan per buyer, actually. Selling off unintentional overstock is not a problem. Of course he can't advertise them here in violation of the maximum price allowed for doing so.
It's doing a business of it as our authorized builders do that you can't engage in unless you're authorized. We haven't had a problem with it as the penalties involved with theft of IP are so severe that it's just not worth the risk.

Bills method in the plan is good for not wasting wood but i feel makes it dificult to get a very nice finsih, as I do it you will get planty of spare cutoff that is best put in the "wood for braces" pile.

Make a rectangular template with a jigsaw and straight edges first, pop this on top of the cabs and using router brushes and a large diameter bit (18mm) route out the now rounded rectangle cutout, rember to make the template sutably oversized :wink: . Now accuratly as possible make a rectangular cover using staight edges and a jigsaw again, undersize this from the hole you just made by the gap you want round the acess pannel (1mm or so on each side) after you have made this part nice and accuratly use flush trim bits to make copies, this panel wont fit the cutout yet due to the square corners.

Get all these rectangular acess covers you just made and clamp them all togther (properly aligned) and put them in a vice so they are stood on edge, get a round over bit with a radius equal to half the diamter of the bit you used to make the cutout (9mm for me) and simply route the coners along the depth of the wood being careful at the start and end, makeing 8 cabs in a go helps at this point.

Fit the panels and hopefully be pleasantly surprised by those sexy fitting corners.

Idealy use a round over with radius as befor but less the gap you left round the edge (8mm flush trimming round over bits are hard to come by), this would give a slightly better fit, but if the gap is suficently small (1mm) it shoundnt matter much.

Hope you understand that and it works out okay if anyone tires this.

Cool. It's just too bad I have a set of nasty looking (but hopefully functional) tops already.

I'm just wondering if you add any extra support to the panel where the casters bolt up to? From the look of it I guess there's an extra ply.

Yeh back corner plywood is 18mm, which the eagle-eyed may have spoted in the first post on this thread. There are no extra supports used but I did put the casters as close to the sides as possible to help with rigidty and the stability when moving them around. The casters are also secured with m6 bolts into t-nuts on the other side, so it will be strong enough.
