Sweet anvil Stash! I’m jealous!

Torin, you sure you ain’t got another one hiding under a bench anywhere? Lol

I'm keeping my 141 LB one, and that is the only other one I have.  However I have my power hammer listed in the tailgate section.

I needed something with which to ring in the new year, so I let this follow me home. Thanks again, Todd (Torin) and thanks for your help loading. Looks like my 250# Fisher is going into retirement.

Steve

Looks very nice in its new home.  Glad it is going to be able to be used again.

That sounds to me like someone used flux in it (borax).  That can melt/dissolve firebrick.   I use high-alumina kiln shelving in mine as a sacrificial base that can be removed and replaced when it has deteriorated enough.

That’s a bummer, I’ve got several good motors tucked around the shop

but the stuff I’d like to run blowers and a big flat belt grinder need something that runs slower

I use VFDs to control the motors for my belt grinder, knee mill, and CNC router spindle.

Well, it was nice to meet you in person Steve.  Once again, I hope my shop wasn't too messy.

Welcome back. I'm in the same general area as you, just south of Allentown, in Quakertown. I don't have any idea of pricing, but I'm possibly interested. The local ABANA affiliate is PABA (Pa Artist-Blacksmith Assoc.). If you go to their website (www.pabasite.org) there is a link to their facebook page. That should get you started.

Thanks Steve.  I did get ahold of PABA's facebook page and the person there said they would post the offer for me to the members.  Let me know if you want to come by and check them out and make an offer.  I'm about 10-15 minutes south of you on 309.

Torin; I'm still blacksmithing and in the SCA; took a forge to the last two metalworker's guild moots.  Haven't heard from Flaxy and Steve for YEARS, been here in NM going on 18 years next month. Still got my Laurel medallion made from a piece of a Pennsic bloom.  We're interested in doing a smelting run out here; got any ore?

For those that don't know, I first met Thomas after I'd collected a few pounds of magnetite sand from the shore of Lake Cascade in Idaho to use for an iron smelting run.  Then I bought about 1000 pounds of powdered magnetite for future runs.  It was the smallest amount I could order.

However I don't have any left, sorry.

Thanks.  Will do.  Was also planning on asking on TheForge too.  Given the weights involved, I was expecting pretty much only semi-local buyers.

I hope things are going reasonable well with you.  I still see Flaxy/Ariadne on the book of faces occasionally.

My most recent stupidity was getting familiar with a miter saw and had a kickback into my hand.  I saw had a gash on a finger that was bleeding, wrapped a couple of blue shop towels around it, and went from the garage to the house.  Opened the door, told my wife, "I had an accident.  It is bleeding.  Nothing has been removed.  Can you please drive me to the ER?

(Didn't even need stitches, they were able to glue it.  But you feel real stupid having to say that to someone.  But not as stupid as not saying it.)

Hello, it has been a while since I've been here (about 8 years).  I recognize a lot of names, so hopefully some will remember me.

I've recently changed jobs and I'm reassessing some things.  I haven't used my power hammer in about 8 years and it has been 7 years since I took my compressor head apart to fix a broken ring and still haven't gotten it back together.

I've also gotten into CNC more (old and new day job) and would like more space.

I'm looking for suggestions on what my Kinyon style hammer and compressor (and 3 ph converting VFD) are worth so I can price them appropriately.  I know I can just get rid of them for scrap, but I'd like to find them good homes.

I'm probably going to keep my smaller anvil and forge so I can do the occasional bit of blacksmithing as needed, but I doubt I'm ever going to be making pattern welded stock again.

Thanks!

Ernie Leimkuhler has a nice article on making an anvil from solid stock.

Much safer than trying to deal with molten steel.

I'll agree.  I bought one the same style and weight at the Abana2K conference and I've been very happy with it!

That looks very nice bigcity.  I remember (at least I think I remember) Thomas Powers recommending those election sign metal posts as great free stock for projects like that.

I see Co2 and CO confused on this site alot,,,I think we  be really carful not to do that!

Yep, CO₂ is a gas that your lungs expel as waste product from the hemoglobin in your blood.  CO is a gas that binds to your hemoglobin and doesn't let go.  It prevents it from transporting oxygen to your cells.  If too much CO binds that way, you can no longer get enough O₂ to your cells and you die.  Worse, you don't feel short of breath, so it hard to tell when it is happening.  I keep a CO detector in the same area as my forge.  If it goes off, I shut the fire off and walk away, immediately!  

Chinobi, I'd give it a go.  You can keep the old wingnuts and swap back if you don't like it.  But it has been the single best thing I've ever done with that saw.  It has been a dream to use ever since I switched.

I have one I got from Rio Grande, but I was always having a hard time getting clamps tight enough on the blade to keep it tensioned.  I finally replaced the screws they had with socket head cap screws.  I think it was a metric thread.  Anyway, tightening them with an allen wrench is much easier than using my fingertips.

Update, I got the low pressure piston out.

Before cleanup



I found the broken section of the ring, or at least part of it



I'm thinking at this point that the aluminum chunk I found was a piece gouged out of the piston face.

The oil grunge came off pretty easy, this is just after rinsing it off with solvent and a nylon brush



I included my finger for a size reference



The rest of the patina came off after some light rubbing with an ultra-fine scotchbrite pad.



And a close up again of the cause of my problems.
 

It took a little bit of work, but I got the bugger out!



Man, was that a deep gouge!



Well, after getting it out, I stoned the face and cut off any bit that looked like it might eventually break off.



Looks like it should work fine now without any further problems.



I also checked out the pin and connecting rod bushing, and there is only a size difference of about .0012" between the two parts. Close enough it should be quite a few more years before I need to replace it.



The ring grooves are in good shape. The maintenance guy at my work who used to rebuild Quincy compressors said they look to be in great shape, and he just recommended flipping the top 3 over to even out the wear.

Well, what I do is cut away the surface of the billet with a face mill using carbide cutting inserts.  Scale, and flux don't stand up to it at all.

I have heard of boiling the piece in water, assuming you are using borax, but I haven't tried it.

Well, I haven't found the source for the metal bits that caused my current problem, but I did find the source for some of the older dents.

I'll post a better write-up when I've had some sleep, but here is what it sounds like:

I found this in the main bore:

And this is what that metal has been doing.

My first gas forge was a natural gas forge I bought from Ron Reil (he of the gas burner page).  Other than being a commercial type forge, I'm not sure what safety features it had, but I commend you for doing a fabulous job of setting in safety features on your forge.

On this side of the pond, I believe most places run house side pressures of about 4-7" of WC. 

Here is the top of the head from both sides:

This is the view from the air filter intake:

And this is what the oil looks like.  Nice an clean:

Well, it was easier to see the oil before it was resized.  Oh well.

These are the documents I've got to go along with the compressor from Quincy.  The QR Instruct is the manual/troubleshooting guide.  The 390-100 is the parts list and drawings for my 390 head.

I know that the gasket set will have pretty much nothing to do with the problem I've got, but I figured I might as well replace them as long as I'm going to be taking it apart.

Oil level is good, and the oil is clear.  It probably hasn't run 20 hours since the last oil change.  I don't really use it unless I'm using the power hammer.

I've got a Qunicy compressor that just started making some heavy knocking noises.  I did shut it off immediately when it started making them, so I'm hoping there isn't too much damage.

I'm going to try and photo-document the process.  I've got a gasket kit, so I'm going to install that as long as I'm taking the head apart.

Here is how it looked when I got it:

This is how it looked after I put in the unloader mod so I could run it continuously when using my air hammer:

And here is the gasket kit:
