Amp techs, what's on your bench?

[beans-on-toast]

At $600, it wouldn't take that many jobs to pay off the investment.

Interesting that you make your own chassis. I've done some in aluminum and copper but usually buy them. Sometimes I've cheated and used metal plate with a wood frame.

What material do you use? Do you find it necessary to weld the corner seams? Ever chrome a chassis?

So what kind of cap discharge to you guys recommend (DIY or store bought)?

 

[B-string]

Mine is very simple. 100K 2 watt resistor with a clip on one end (for chassis ground) and an old test lead that you can screw a clip onto at the other end. Encased the resistor in silicone, used part of a small paper towel roll as the form.

3D printing is a long way from being a viable manufacturing option for any any kind of parts that may require stresses. If you want a nice custom chess set piece it's great but if you need something to spin 10,000 RPM's don't count on it. I have looked at 3D printers at a cost of $850,000.00 and they are just not there yet. I recently looked at an aluminum prototype made on a 3D printer that took 4 days to make and the cost was a couple grand. Certainly not a viable option to just machining the thing.

3D printing is going to be the wave of the future but definitely not the present.

Waterjets are on the way out to be replaced by the new Laser machines which are faster, cheaper, cleaner, and yield a better product.

Here are some of my parts.

Really nice work; was all this done by CNC?
In Maryland / Northern VA area, lasers are replacing water jets and CNC machine for sophisticated sheet metal work.

Link Removed has an amp tech tool section. They sell one for $15. As has been pointed out, they are easy to build.

If you have to deal with power cord strain relief bushings like this,

you might want to get a pair of Heyco strain relief pliers. They can be pricey but I found a good deal for some R-29s on amazon.

Steel, welded seams. More commonly its refurb old chassis, weld them and powder coat, chrome is possible but not done it. More usually we work on car chassis (which arne't water jet cut): Invalid Link Removed

Looks like very interesting work to be involved in. I'd love to own a Morgan. Cars that you can bolt together from the chassis up can last forever. Much like many vintage amps.

Hey I was going to try to host the images for that vintage Gates compressor rebuild and start a thread on it this week. Where do you guys think I should put it? Misc? Here in amps?

 

[Mr. Foxen]

I did mention an electronics making corner like luthier's corner. Should get some backing for that. Might get a bit more feedback than the work in my blog.

I would say here unless you want a separate thread to contain it, then in amps. It is an amp, just a special type.

 

[B-string]

Don't know if it would have to be in effects? Contact a Mod.

 

[beans-on-toast]

I think that it would have a wider exposure in the amps thread.

 

[B-string]

I agree, but never hurts to consult the Mods

Thank you.

All CNC, most of the milling you see is done in a lathe. Some of the rectangular parts were done on a 5 axis mill the rest were either on a 6 axis turn mill or 8 axis Swiss lathe.

If you look at the bottom of the pic about 3/4 to the right there is a small rectangular aluminum block, that part is made out of round bar on a Hardinge Quest Twin Spindle turn mill/lathe. Technology has come a long way for sure.

These are all recent jobs, the parts range from Aerospace to Weapons, to Firearms, to Electronics, Medical Devices, Cryogenics, and more.

 

[two fingers]

Before = nasty

After = shiny!

Stay tuned. I'll PM a mod about where to stick it.

 

[B-string]

Nice! Hope they say to keep it here.

 

[two fingers]

I ran it by a mod and he gave the go ahead for putting the new thread in amps. Coming soon.

 

[B-string]

Excellent!

Yup, exactly. I know you could say it belongs in FX, but I think this sort of gear fits better with the technology discussions in this forum than it would fit over there, so I'm happy for twofingers to go ahead and start his thread about the recon job here in Amps. Looks like really nice work, by the way.
