IGSL

[SVEN1]

Found a used Thermaltake external hard drive this spring at a garage sale for $2.00. It didn't work but, figured the case might be good to house a metal detector.
The ISGL fits onto the tray that the HD was screwed onto. Only a few mm clearance for the one cap.

Nice work there - keep it up..

Very neat job.
The Hammond enclosure has 4 screws to secure the front panel. One in each corner. Have you placed your own panel over the top of this?

[petravka]

First set screws, after the set engraved plate and potentiometers. Screws remain masked.

Golfnut, Sven1, Petravka - NICE JOB!
Indeed.
And also nice new ideas how to do some things better.
Cheers!

Nice job, did you weld those bends on the steel pipe?

[golfnut]

I reckon they are aluminium?

If the are - you dont have to weld it, you can solder it- or sodder! if american.


Just need a blow lamp and solder sticks (and a stainless rod to scratch the melt pool base)

There is nice trick how to solder Aluminium!
Before soldering, merge that Al area parts in machine oil , than use sharp knife and scrape areas which are about to be soldered and joined together.
Oil should remain on surfaces and will prevent Al to get into touch with air and Oxygen from air and to oxidize fast, as it usually does if there was not oil applied.
Than use extra powerful soldering iron and solder those two parts.
Fact is that Al is easy to join with tin if Al surface is perfectly clean and heated with proper temperature.
Problem lays in fact that Al is oxidizing very very fast when exposed to air.
So oil is there to protect Al surface from oxidizing, for a moment, until is heated and joined with tin.
Certainly, ordinary soldering iron (usually used for soldering small electronics) is not enough powerful for such operation.
I have Weller with "7","8" and "9" peaks and tried all of those to solder Al, yet without success, because it is not powerful enough and Al is cooling very fast.
Yet, than i tried same with much more powerful soldering iron (300w) and got success!!
Neat trick, isn't it?

Very neat trick indeed! and it works. I have not tried anything as heavy as soldering two aluminum pipes but I have used this trick to solder wires to aluminum foil so I had a good connection for Faraday Shields. Although later I found that this was not necessary.

This is welded aluminum. Later I realized that bending is not a problem. You need to a thicker wall (2mm) and R-6 cm

Hi this is the sort of thing I used to make a lightweight ally muffler for a petrol modle aircraft engine..

Nice pictures. The top one looks better than the best I have been able to manage so far

Did you use a spring or something inside?
