You do need a new cabinet! Especially one you've made yourself. I'm using a Kappalite 3012HO.

[quote name='3below' timestamp='1468266685' post='3089761'] 20 mm/s is a pretty impressive cutting rate. Apart from the upfront capital costs I can see many advantages of laser cut for sheet work, not least no dust (other than initial down size from 8 x 4), no blade sharpening, much less edge fettling etc. Any thoughts of selling flat pack BFMs? [/quote] I've not yet been able to buy an 8 x 4 sheet of ply for the laser. It's ply specifically for laser cutting and is not readily available. It's all to do with the glue that glues the plies together. Normal ply just burns. Once I've finished the build and confirmed that everything fits together as it should, I shall be making kits available. If anyone is interested, P.M. me.

Just back from the workshop / shed / man cave, so on with the build report. This afternoon I installed the duct braces, ducts, throat sheath braces, the throat sheaths and the phase plug dome. I've also fitted the top hats as I also want to use them for P.A. First to be fitted are the duct braces. These are glued and slid into their slots rapidly followed but the ducts. Also glued and slid into place. The hammer makes a great weight here as the paint can is a bit too large. [attachment=223294: DUCTS INSTALLED.jpg] While the glue is drying I made up the 'modified' throat sheath braces. When all the glue was dry I glued and stapled the throat sheath braces in place and sealed the tophat holes with glue. [attachment=223292:BRACES.jpg] [attachment=223296:BRACES INSTALLED.jpg] Now comes one of the few bits of actual manual labour involved in the build. I had to sand the front of the duct to an angle so that from the edge of the brace to the bottom of the duct was not a step. This took about a minute per duct. I also made a strip of ply that slotted behind the braces so that there again was not just a butt joint between the throat sheaths and the baffle. Everything here is tabbed or slotted so that it just pops into place. [attachment=223296:BRACES INSTALLED.jpg] All glue that had squeezed out where I didn't want it was chiselled off and the throat sheaths were then glued and stapled in place. The throat sheaths are also made from flexiply and are slotted into the baffle. The last thing to glue is the phase plug dome. Polyurethane glue does the job a treat. I was a bit concerned that it might might melt the polystyrene but all is OK. [attachment=223295:INNER HORN & BALL.jpg] I also found out that the glue gets on your hands really easily and doesn't want to come off again. I also found out that once it's on your hands the finger print recognition on an iphone stops working.

It didn't take that long to actually cut out. It could be worked out as it was cutting at 20mm / second but then I engraved the part names on each bit as well. I would guess that it took 2 to 3 hours in total. Mind you, it took quite a few days to get the plans converted into DXF files for the laser cutter. I was however working in and around other cutting and engraving jobs. I've also got a well equipped workshop. Band saw, table saw, thicknesser planer etc. and I've used them extensively on other builds but the idea behind this project is to make a cabinet kit that can be made with the minimum of tools and no experience and also to be super light but still sound fantastic.

Many thanks. I've got one of these. https://www.youtube.com/watch?v=gLzZRGvu85Y Dual tube, 100w and a 60w.

Why thank you sir. Probably post again later today, just waiting for some more glue to dry.

Managed to do a bit yesterday after all with my 4 year old grandson, Tom, giving me a hand. Time to fit the horn sheaths. I've used flexiply for the sheaths and cut it to size on the laser cutter. I had the power too high on the first one and it's left a bit of soot on the edges, not a problem though and power lowered for the rest which has worked a treat. I'm not sure that I really trust the glue to make a good seal on 1/8" ply on a butt joint so I've added a few extra strips of ply just to be sure. [attachment=223249:READY FOR HORN SLEEVES.jpg] Marked out where the horn braces are and where the sides end and glued and stapled together. Using flexiply made it so easy. Just push down with one hand and staple with the other. [attachment=223250:HORN FITTED.jpg] Now the glue has dried I used the Stanley knife and a straight edge to trim the horn sheaths to size. 3 cuts and it was through. I forgot to add glass paper to the list of tools required for the build. Sanded the horn sheaths flush with the sides and I'm ready for the next part of the assembly, the ducts. Once glued in place, the flexiply is as rigid as non-flexiply. It's solid! The staples worked really well on the top, bottom and sides holding everything tight until the glue dried. [attachment=223251:HORN CUT TO SIZE.jpg] More later. P.S. I've used smaller, black & white photos to save on disk space.

It was in the Red Lion in Gravesend in 1980 something. As we came to the last note of the song, the guitarist raises his leg high for the dynamic last chord. However, everyone else could see that when he played the chord and brought his leg down again, it would miss the stage by quite a way. Tried to tell him but he wouldn't listen. He played the last chord, brought his leg down onto nothing and flew off the stage. How we laughed! He was OK though, just his pride was hurt, oh and he split the knee of his best patchwork trousers.

Not Sunday, Most of tomorrow is set aside for being Grandad.

Thanks. Watch this space for the next thrilling episode.

Bummer. I suspect that a new jig saw might be a little bit cheaper, probably by about £6000. Nothing wrong with your build though. It's looking good.

Started assembling my Jack today by installing the horn braces to the sides. If you've got the plans you'll see that I've modified them to make assembly easier. [attachment=223097:SIDES & HORN BRACES.jpg] Using my amazing horn brace brace and the can of of tough cab as a weight all went well. all the braces fitted in the tabs perfectly and are all square and vertical. Plenty of glue squeeze out too, but that's what the chisels for. [attachment=223096:HORN BRACES GLUED.jpg] [attachment=223095:HORN BRACES FITTED.jpg] The glue has dried so I might as well fit the baffle, top and bottom. This is so easy! All the tabs line up and everything just slots into place. perfectly square too. I used 3/8" staples to hold the sides to the top and bottom, i would have preferred 1/2" staples but my son seems to have used them all and I didn't want to stop head off the Screwfix for some more. The 3/8" staples worked great though, holding everything together until the glue sets. Inserted the baffle before fixing the top and with the top stapled I laid the cab on its front and again used the can of tough cab as a weight on the baffle to get a good, tight fit to the horn braces. [attachment=223099:CAB ASSEMBLED.jpg] As it stands I can easily lift the assembled parts with my little finger. I'm liking this a lot.

J15s gone I'm afraid. They ended up on the bonfire due to total lack of interest from anyone. Starting to build tomorrow, not too early though. Watch this space!!!

I’ve wanted to make a super light cabinet for quite a while now and as soon as I found that Bill Fitzmaurice, known and respected by all here on Basschat, had designed the Jack 12 Lite I bought the plans intending to give it a go but why not make it incredibly easy to build as well. Having a laser cutter, I decided to cut out all the parts in advance, in effect making a Jack 12 Lite kit. Having built a few of Bill's design in the past, OT12s, T39s, Jack 15s Jack 1s2 and Wedgehorn 6s, I already know how good Bill designs are. I set to work transferring all the parts needed into a cad program, loaded them into the laser cutter and cut them out from ¼ ply. While the plans were in the cad program I added tabs so that all the parts just slotted together. I’m quite confident that I got all the tabs in the right place but only by making the cab will I know for sure. The only tools I intend to use are a staple gun, Stanley knife, a phillips screwdriver and a sharp chisel, ( the chisel is used mostly to remove excess glue ). The hammer is in the photo because everyone has to have a hammer and it might come in handy. Polyurethane Adhesive and a mastic gun. PL construction adhesive is used in the States but is next to impossible to find in the UK but a quick visit to Screwfix will get you fixed up. As long as it's gap filling you're good to go. A can of Tough Cab paint. Useful as a weight as well. For a bench I've used an old school desk. Here’s 3 photos. The 1[sup]st[/sup] is the bench and tools. The 2[sup]nd[/sup] is the sheets of ply ready to cut and the 3[sup]rd[/sup] is of the parts cut out and ready to assemble. Construction starts tomorrow.

Love the look, especially in red!

I found that out in 1972. Being lefthanded I couldn't try before I bought and had to order one, but, it's Fender, it's going to be fantastic. It wasn't, it was total rubbish. Still being lefthanded, I still can't try before I buy so I shall remain Fenderless forever.

The luminous dots do last all night, I think the led lights charge them. You can feel them on the edge of the neck but I don't notice them in the centre of the neck. They do slide about and fall off when they get warm. I like them though as the normal dots disappear under different colours, red mostly. I was thinking of clear nail varnish over the top of the dots but that seems a bit drastic and permanent. Still thinking about it though.

Wouldn't get a lot of wee in a hip flask I'd of thought.

Thanks for the clip. I don't know. Singers good but it just doesn't look right without the stacks, more of a Rainbow tribute than Rainbow. They're a bit static as well, not much of a show.

Coffee, cheese sandwiches and watch the F1 qualifying for me.

Mine arrived this morning as well as the £1 digital credit from Amazon.

Worked for me!

No Brian or Steve but a brilliant gig. Wish I'd been there. https://www.youtube.com/watch?v=Bghtzail-5E

They only carried their guitars, easy! They should try Hastings caves and carry all the gear in and out!
