VK112: Combo to Head Conversion

Okay, so im gonna convert my Valveking 112 to a head. I got my wood today. The cabinet will be made out of pine. My dimensions will be 21"L x 10"W x 8 1/2"H.

My plan is to build this in woodshop over the next couple weeks. I will cover it with tolex, once i get money haha.

Pictures will be up soon.

For those interested in doing this:

What you need:
Wood, enough to make the the enclosure, panels, and supports.
An amp
Hardware (handle(s), corners, and rubber feet)
Access to some sort of saw.
Stain or tolex.
Black Paint.
Wood Screws.
Drill bit slightly smaller than your wood screws.
Wood filer or putty. (if preferred)

First, Take the amp out of it's original enclosure. Measure, measure again, and measure again. You want to give it enough room to be able to slide in easily but you don't want any bad gaps. You want enough room to be able to remove the tubes, so make sure the height you choose will allow for this.

Second, Make all the pieces.

Third, This is very important for making it right. Take the two sides, and glue them to the Top piece. Leave the bottom piece out for now.

Fourth, Once you've glued the sides to the top, it's time to mount the amp. All amps are different how they are mounted, depending on if they are top mount or bottom mount. Mine was top mount so that is why i glued the sides to the top. Now place the amp in the enclosure, and line it up how you want it. Now some people will have enough room just to drill through, I didn't. What i did, was take four nails, and tap them in the wood a little bit through the other side of the amp. Then i removed the nails and the amp, and drilled a hole where the puncture was made from the nail.

Fifth, Glue the bottom to the sides. Line it up and glue.

Sixth, Sand, Sand everything flush and nice. IF YOU WANT TO ROUND THE CORNERS, OR EDGES, HERE IS THE TIME. Round your corners either by hand, or with a palm sander.

Seventh, Screw the wood screws in. Pre drill the holes (not to close to the side because this will affect your edges.) Use a counter sink bit to counter sink the screws a little. Then place your Screws in, If you don't want your screws to show, get some wood filler or putty and put it over the screw.

Eighth, Tolex or stain. Tolex is quite expensive, but if you go to joann fabric and get vinyl it's only about 12 bucks a yard. If you don't have experience with tolexing, research it and practice on pieces. For Staining, use 220 sandpaper to get it nice and smooth, then stain.

Ninth, Paint the inside black. You do this so if you do have any gaps, they won't show through.

Tenth, Install the handle and rubber feet.

Eleventh, Put the amp in, and the panels.

If you Choose to you can cover the panel with grill cloth.

i would build that out of a hard wood, pine is real weak to carry such a heavy load, and also a fragile one.

Well, I got the wood for 5 bucks, so i can't really complain. And I will be putting supports in made of much better wood (scraps from my schools wood shop.)

Also the amp doesnt really weigh that much so it should be fine.

Thanks for the input though.

Good luck, man. I wonder how much it'll weigh when it's done? I might consider this mod for the future...

Um... Lp, cabs are usually made of either MDF or Plywood (Birch or otherwise).

Probably Around 30 pounds, considering the VK by itself is about 42 pounds, minus the speaker and like 11 inches of wood on both sides.

well considering the amount of money your going to put into the speakers i would just buy better quality wood to build it with, trust me, you will appreaciate it in the long run.

what type of speakers are you using, and how many?2-4, possibly 6, 6 would be cool.

wait you can only put one in there, nvm. but mdf would be better wood.

He's not doing a speaker cab and if he was pine is the better wood to use. Pine is great for guitars and speaker cabs the problem is it dents easy so guitars are rarely made out of it and fender uses it for cabs.

pine should be fine, they make beds and chairs and **** out of it.

how will you join it? If it was me I'd use finger joints, but I've never built anything like this before. is there any danger heat from valves can melt glue I wonder...?

ohhhh, my bad, i totally read it wrong. you said cabinet so i thought speaker cabiniet, if your just going to enclose the valveking then pine is a very good choice.
hope it works out. building a halfstack speaker cabiniet would be a cool project though. i might build one, and use your idea as a valveking as a head.

But for now, I built a pedalboard today.
