Just remembered this.

Nitric acid is used to clean copper and copper alloys prior to adhesive bond strength testing. Very effective. Testing standard lists 197 parts water, 30 parts nitric acid...

I've got a nibbler, damn difficult to get a nice straight edge (maybe it was the beers) even with a guide and was only zinc steel, and forget going around the corners.

Basically if you need nice...

Hi raschwar,

Photos are impressive.

Have not cleaned any brass for quite some time and what I do remember was not as heavily tarnished as that.

I would suggest the following Jif cleaner and...

Another option are the expanding mandrels from machine tool suppliers. Just throwing it out there.

If you mark jaw position on the piece before taking it out of the lathe and then using the...

I think ur on the right track, though you could probably just be cremated in a wheelie bin. Shredded plastic from drums does get used as feedstock for industrial furnaces so no problem...

Hi,
Can't offer specifics, just some suggestions.

Go visit a specialist tooling supplier like Comag (just down the road and around the corner from H&F)

Hi,
There is another option available. Brass cylindrical hidden hinges, I don't know the correct name, but these work quite well. To use, you drill two holes insert hinge a screw expands the wedge...

Quickest link to rapidworks info is to visit Nextengine website (this is what I have). Their software scanstudio also works well at assembling scans.

Hi, I understand the whole piracy aiding abetting issue and to be honest i did not even think of this.......but i found something in one of the references that I had been looking for, for a very long...

Problem is that idiots like that cause things like OHS and Workplace health and safety to be invented. Which then results in you being too busy writing risk assessments and such to have time to do...

Most impressive! How long did it take to make?

Hi,

I use Rapidworks seems quite good so far as on the learning curve still. Solidworks I use for CAD but have not tried it for importing and joining point clouds/scans.

Check out website David...

Hi DaveJ,

Seems scumbags are everywhere. Sounds like someone who knows too much about your place. If you do go down the camera route keep the following in mind. Hope this helps.

Cheers for the links to the books

Had similar problem like that years ago. Never figured it out, but was suggested that could be a couple of causes, old yeast, dirty bottles (doubtful on this). We used sodium meta to clean bottles...

In the middle of doing research into one of my medium term projects, gun bluing, which is a method of rust control. May help.

It is very likely that the bolt is hardened.

To see if toolrest is hardened get a centre punch and a light hammer and compare indenting it to indenting some mild steel.

Your problem could be...

gap and windows are prime source of noise escape. How best to reduce noise depends upon what type of noise you are making. Hammering (low frequency thud) probably best to go for high density padding....

hi raff35

mate I would not sell it, see if you can at least park it at a friends place. Breaking it down to move and stacking somewhere is always risky as Ive found, its amazing what gets lost...

I don't know if this is friendly to fibreglass but I've been told panel beaters wet sand using white spirits (?) aka prepwash. This avoids the issue of water being absorbed into the bog or paint so...

Hi wsal,

Like already mentioned there are numerous copper alloys. Suggest that you first determine the ideal diameter and colour that you need. Then look at stockists to see what alloys are...

Grab a action ally catalogue, used to be online and probably still is, gives a brief summary of what you can and can't do with the different alloys. ie machine, weld .....

Firewood can work a treat as do old fence posts. Be warned though cracks can cause large sections to fly off at random.

One of the benefits of metal lathe is rigidity of whole machine and potential tool rest if on cross slide. Closer tolerances of slides mean that dust more liekly to jam them though. I have old DSG...

Matt,
Both designs will work, but I agree with Manucka Jock, bracing would be a good move. Triangulation always produces a stiffer frame.

On the side a benefit of the basic workbench design is...
