After passivating in citric acid what does it come out looking like?

Is it a little dull and grey or bright?

I've been making cheese knives out of stainless steel shorts, so unknown grade stainless.

I recently saw a post on instagram where the guy was forging stainless jewellery and he said he was pickling and passivating the stainless in aluminium sulphate before polishing.

Googling explained what the pickling and passivating process is but I couldn't see any references to aluminium sulphate being used.

Also if the passivating process leaves a coating only microns thick wouldn't polishing wear that coating off?

Does Anybody have any experience with these processes?

So what tooling have you made for it Andrew?

Happy to hear tips on how not to set my self on fire. 

I can see why early bolts had Sq. heads any idea why they are still used in certain applications like lathe tool posts?

I guess the heads are smaller so they can be closer together 

Frosty the pipe coming off the elbow is only short as it has a shut off valve in it.  I plan to put it on a stand with the gas bottle below and a reasonable gap between.

does that alleviate your concern?

Cheers mate

Does anyone have access to either a Silver No.3. Or Buffalo Forge 66?

im looking for details on missing parts so I can make something up similar to complete my latest drills.

These are what I have for my postdrills

I started building this gas forge in December 2015 and it got mostly done with the exception of the mortar and paint.  Now Feb 2017 it has got those two items completed and has been put to use.

It even cooks lunch while cooling down. Started with corn finished with a few snags.

If you want inspiration take a look inside this book.

The Art of Fine Tools.

Since we have a 3 week old baby and I'm not getting any sleep I'm staying out of the smithy until I'm not a complete zombie.   Hopefully I'll either get used to no sleep or things will improve soon as I need to get things done.  In the meantime I'm researching the New Kinyon Design power hammer which hopefully I can't maim myself doing in  my sleep deprived state.

Where can I find the latest iteration of the plans and have there been any advancements recently?  Is there a PDF version?

I did see a video of a twin rod head on YouTube as opposed to the specified square run in UHMW guides.

i need to find out what equivalent parts are available over here and do a costing on it

I noticed some double hit when you stop is this common to all, what causes it and how do you resolve this?

It's been a long time since these plans were released.   Has there been any further advancements made with the design? 

Photos have been emailed.   Hope they are helpful.

I have taken a bunch of photos with an imperial ruler,. We do metric over here.   Give me an email address and I'll send them to you.

I have one I'll try to did it out today and post details.

Overtime I try to go to any of the Blacksmithsjournal.com links to buy the editions it gives me a can't find the server error.

Does anyone have some digital copies they bought and want to sell?

Thanks I'll have a look

I asked for a link so I can see what it looks like.  I'm in Australia. We do have some Harris gear here but it comes from the Europe plant not the USA Milwaukee? Plant.

so the models etc will have diff designations etc. and I'd have to tell the store guy this is the one I want to order in as they only sell a few of many different brands.

Anyone got a link to that all states torch?

Thanks for those photos.  What is the item at the bottom of the last photo?

Thanks Wayne.   What is a gas saver, how's it work?

Smoggy,.  What is your Oxy compressed air set up?  Details, photo?

So far all I'm hearing is positives except for the associated costs with gas, however most of you seem to prefer to live with the expense than be without 

Spot heat, heat treat & cut. Are what I'm focussed on. 

Brazing I haven't seen a need.....yet.

As for welding, I have 2 stick and a MIG. So that isn't a nessecity unless it can do something the others can't and is easy to learn.

I looked a some LPG (similar to propane) torches that I wondered if they would get hot enough, fast enough?  Anyone used ser a straight propane kit?  I have the small disposable Mapp/Butane and want something much, much more effective.

I also saw the LPG/Oxy sets which are about 20% cheaper than the Acetlyne kit the same. I'm told they work just as well but cheaper to run, although they can't weld. I assume therefore they are not quite as hot?
