Rebar identification







Looks to be checkmark or V followed
13S4 or
1354

Now to decode it

It is checkmark... makers mark

13  not sure, maybe metric diameter
S Billet Steel
4 420 grade aka grade 60 or 60 KPSI yield strength

and there are two dots below it which are what Roy at
Christ Centered Blacksmithing said was good

Happy man here.  I see transfer punches and such in my future



Found this which has a 13 in the same position but am not sure what it means.

Wood handled lead hammers


Found these wood handled lead hammers at a garage sale this week for $1 each.  The sell had no idea what they were.

Rebar Grade Chart.

Roy of Christ Centered Ironworks did a vid on forging rebar.  Mentioned it was marked for grade

Did a little digging and found this chart

I have 100s of lbs of cutoff's from highway construction.    That may mean they are grade 60.  Need to look for marks.

Sand Muller Tub Canidate

A fellow who collects scrap has this.    I am going to cut off the feet and cut it down for use as a muller drum.

Tool Tip: Propane torch soldering tip

I found this propane soldering iron tip.  Its the cats meow for soldering automotive wires.   It's not new and I don't know where you can find them.

It slips over then torch end.   I had to reduce the outside diameter of my burnz-o-matic torch to mount it.

Live Center Bearings

This was written a while back but never published.


Found a video on YouTube regarding fixing a similar live center.

Amazing "Wet Paper Towel" Method of bearing removal on skully jones live center


Worked as advertised.  Used a cut off socket extension to drive the towels in.  It takes a surprising amount of stuffing.


Not fun picking the paper shreds out of the bearings.  Not sure if both bearings are good.   The bearing number is Timken Part Number A4059.  It looks like a uxcell 30202 will fit even but its a mm wider. ebay has 3 for $10.https://www.ebay.com/itm/30202-Single-Deep-Groove-Ball-Bearings-Silver-Tone-35mmx15mmx12mm-3pcs/351957893328?epid=2136364554&hash=item51f25340d0:g:sxcAAOSwUwFaS5RO

I am going to clean them the best I can and see if they work.

And they did.  Have them a little too tight but it runs cool so I am going to live with it.

Image of aluminum pouring device and muller arbor

A heat shield has been added it. Greatly improves comfort while pouring.  2nd and 3rd images are the arbor I plan to use for the muller.   Today I managed to get the nut loose and remove the saw blade the shaft is 1 1/2 inches.
