Bitx40 All done

 

It's done took a few days of mods and hole drilling still have to work on my LCD display cutting in .....as you can see not so good at it yet hihi.

In total it has an added Keyer, Nescaf Filter and zero beat, soon AGC once I either build one or get a few boards.

From left to right FS // CW FS // Nescaf Filter Center // Nescaf Filter Bandwidth // Nescaf On/Off // Vol // Head Phones // Mic.

Above the mic and phones is the zero beat and the led for it is the yellow one above left of the tune lower right of tune is nescaf led. The zero beat is not the built in one but a LED version based off a 567 tone detector, I have built a few and love them.

All in all it was a fun build and can't wait for some park ops.

Nice job getting all that stuff on the panel! I put the mic, phone and key jacks on the side of my box to save space on the front panel for future additions.

Aperture all within display outline, so a file and a bit of judicious 'elbow-grease' would cure any uglies. All those extras! Well done!
 

I always drill 4 holes on the inside of the window lines and use a hand fret saw to cut the center out.
Then you need some elbow grease to make the hole neat.

Now if you can get a bezel for the display, then you are in business!

Used a combo of Drill press and punch with some files. I need to get a saw even a nice small metal hand saw. It was all a squeeze for sure AGC is going to be tough hihi

I 3D printed a bezel to hid my similar workmanship..? I have attached the .stl file I used.
I could print one for you if you would like.

I used to have that same nibbler, a couple of them in fact. Don't nibble
anything too heavy, that's where both of mine went!

When I cut the hole for mine I used a 1/8" endmill in a milling machine.
If I didn't, any other method would have resulted in a very wavy line.

Here's the answer to making neat square holes like for the display. (

I've used a fret saw, too, and it works pretty well. I draw an outline and use C clamps to hold a small metal bar on the line to prevent the saw from drifting outside the cutout. That and a little work with a file does pretty well. It's still nice to have a bezel though.

When I did mine someone recommended using a wood chisel to make the cutout.? I got a set of cheap chisels from Harbor Freight and clamped the panel between a thick piece of steel as a sacrificial backing and a straight edge.? I laid the flat part of the chisel along the straight edge and started making a series of shallow cuts until I made it through the material.? I was a little off on my measurements but otherwise I think it turned out pretty well.

My solution was to mask the portion of a piece of plexiglas where the lcd would go and paint the rest of the plexiglas black. ?Then mount the lcd behind the previously-masked and now clear part. ?The controls are?mounted on the black part. ?The advantage is no cutting. ?The disadvantage is you have to remember it is plexiglas!!

Just leave the LCD opening as is and get this nice bezel to dress it up.

I bought it on Amazon, but they no longer carry it. The closest I can find now is from the Container Store:



They also have one that is a bit larger.

I just ordered some simple ones with no screw holes that I can custom my way in, thanks for the offer Dave wish I had my 3d printer still. I plan to get a hand saw, the hand work doesn't bother me yet as long as its not wrapping torids. My biggest issue now is will I have room for AGC I have started to mount things to the top of the case hihi.

?

?Nice tips and pics guys love the ideas.

This Bezel fits the supplied LCD.? You use flat head mounting screws, this covers them.

I use supports when printing it, with front side up.

This is rear view.?? The recess snugly fits the metal rim of the LCD.

I also have spacers to mount it nicely.

I will find the files.? I think I uploaded them before.

Do you have to be careful when drilling the acrylic to avoid cracking?

Phil, W1PJE
 

Drill very slowly i.e. don't be in a hurry. Acrylic melts and the bit will grab the sheet and spin it and you could get hurt.

I have built many projects with it and even built paddles. I used water to cool the bit and end mills.

I used to save the shavings and dissolve then is a small glass bottle with chloroform and use that as glue.
I learnt this from a local sign board maker in the old days.
