Solid Body Electric Lap Steel Guitar

After the success of my acoustic guitar project I've been spurred on to make a solid body version. I bought some stunning curly maple a while ago and this project will be perfect for it.

I've decided to go for "Les Paul" style construction - mahogany topped with a curly maple top, rosewood fingerboard with some nice inlays and twin humbuckers. But I want the guitar to have a lot of the character and feel of the acoustic, so I'm adding in designs features from that. Let's see how I do.

Time to rout the rebate for the body binding. I used a router with a smaller bearing to make the cut.
The the plastic binding is glued into the rebate with thin super glue - a quick and easy way to do this. The whole task took less than ten minutes, and the binding was easily bent to follow the bodies curves.
The excess binding is scraped level with a cabinet scraper. Watch the edge of the binding - after scraping it is very sharp! I softened it with 240 grit sandpaper to save getting blood on the maple top ;)
The guitar was given a thorough sanding from 80 grit through to 320.
The the top was stained with a yellow alcohol based stain.
The whole guitar was given a coat of cellulose sanding sealer to keep dirt out of the pores and seal the stain into the top.

Looking very good!

Next task is to fit the inlays and fret markers.

I used a router with a 3mm straight cutter to remove most of the waste by eye.

Then using chisels and gouges I chopped back to the lines.
Superglue was used to fix the inlays in place, with a little clamping pressure to hold it until it cured.
The excess inlay was removed with a file then sanded flush. Any gaps were filled with superglue and sanded flush again.
The "frets" were marked out earlier using a knife. I now deepened these with a saw. A block to act as a saw guide makes life simple.
The "frets" are strips of maple veneer. I cut them out from an off-cut of veneer and made sure the grain was parallel with the edge - any run-out would make it liable to split out.
Once again superglue was used to bond them in place - it wicked into the gap and fixed them securely.
With all the frets installed and then sanded flush it was time to glue the fingerboard into place. I sanded off the sealer under where the fingerboard would go to ensure good glue adhesion.
Then clamps and a caul to hold it in place while the PVA sets.
With the fingerboard in place and sanded flush with the neck it truly looks like a guitar!
I marked out the location of the tuners and drilled them out - 1/4 inch for the shafts, 9mm for the bushes on the upper face.

 

Next the bridge.....

I designed the bridge in Sketchup and printed out a full size plan - I stuck a copy of this to the wooden blank and used it as a guide to drill the holes, rout the groove and shape the wings.
Careful measurement is needed to position the bridge in the perfect spot. When happy I drilled through two of the holes and left the drill bits in place as guides.
Then I removed the finish from beneath the bridge (so the glue will stick!) and glued it in position with PVA and a few clamps.
Bingo! Now its time to mask off the fingerboard and bridge and do some final sanding.
As it was a pleasant day I spayed the guitar outside of the workshop. Two good coats of sealer, sanded back when dry, and eight thin coats of lacquer were applied.
And when it was dry I brought it into the workshop with a very big grin on my face!

I left it a few hours to cure before flatting down the lacquer with 1000 grit wet and dry paper. I'll give it a couple of days before buffing the finish out with compound.

Meanwhile I want to think about where the controls are going to go. I also need to skim down the pick-up surrounds - they are designed for an arch-top guitar so they don't sit flat on my guitar.
With the finish cured and polished out with t-cut I installed the tuners. Make sure you pre-drill for the screws or there will be tears!
There are separate bushes to press in from the front - they look very smart.
Next up I made a brass saddle for the bridge - this one has the slots rough cut so I can get the guitar up and running. I'll replace this with a fine-tuned version when I'm happy with it.
Same with the nut, made from 3mm thick brass. Brass is easy to work with a hacksaw, files and sandpaper. A spot of superglue holds it in place.
I made up six bushed to take the ball end of the strings on my metal lathe. These were turned from 8mm brass.
Withe the holes from the bridge brought through the body to the rear, I enlarged them to 8mm and fitted the bushes.
Next I reamed out the holes for the controls.
With the volume, tone and pick-up selector switch fin place I fitted the gold coloured knobs to complete the top.
I drilled a 6mm hole for the output jack and reamed it out to 20mm. The reamer doesn't tear the fibres, so makes for a stress-free job.
A little work with the soldering iron...
And she's ready for a test play!! I'm very pleased with the way it sounds - now to make a cover for the control cavity and make some final tweaks to the nut and bridge.
