Op 1 on the rods is done!!   Now I have 24 tapped holes and some rod bolts to make and we can profile and part off the caps and then finish the rod as an assembly

Whiskey has been hard at work doing some heat treating   crank pins in the furnace and quenching

Dave
PS   I think he has some splainin to do regarding that fly press!

Do you know if Whiskey quenches the bits while they are still in the stainless steel wallet, or are they removed first?

It is the journey that matters, not the destination

Sometimes, it can be a long and winding road

He kept the first on in the pouch.    60 to 65 Rc..before tempering......harder than woodpecker lips!    He's going to draw the temper now....A2 air hardening

Huh... that's interesting. I'd think it would be harder to cool the parts quickly if they're still wrapped in the stainless... Very interesting!

Ok   7 rods done tonight  I'll do the others tomorrow as I run 3rd op.   While I was in the shop I mad a Joe Pieczynski small tap wrench its nothing more than what you see.  1 inch OD by .350 wide with a 0.144 hole thru and a 10-32 sets crew.   It works amazingly well for stuff from 4-40 down.   Got to give the new vice a workout too!....sweeeeeet!

Very nice, Dave!  That is a cute little tap handle.  I may have to make one of those.  I really like my little red tap handle, but I can see having a round knob like that could be really nice :)

And excellent use of the Piper Vise!  Extra credit for that! :ThumbsUp:

Joe recommends wire brushing the knurls after as they can be a bit rough on the fingers....I would second that advise!   But I really like it..and I had the tool made and dusted in literally 10 minutes.....Going right into the tool box after.

Thank you Roger......It is very satisfying ....to say nothing of making tools on a lathe I completely rebuilt from "boat anchor" status....nearly 10 years ago.

OK Bubba!    3rd operation done on rods.   Profile the rod cap and part off, then finish cut the rod bolt face.  I need to work on part organization.   Especially when dealing with 12 each!   I had dozens or part sorter boxes while William and I were racing....do you think we'd have ONE I could use?    :ShakeHead:

I'll buy some more, but I cleared out the bottom 3 rows of drawers of this hardward sorter for the moment.   

In each is the embryonic rod, and the profiled, but not yet brought to thickness rod cap, with orientation marking  so the can go back together.    Now I looked at my screw assortment last week and said I have plenty of 4-40 grade 8 screws.........I was wrong.......they're M3's....... :facepalm: :hellno:

So Op 4 ,   bolting the parts back together and bringing to thickness will need to wait a couple of days.........

If you have a container store near by stop and get you some stackable divided trays. They are great for the long term projects and ones with a lot of tiny parts. Sound fimiliar?

YUP    the RC community has brought it to a level of art form....because of all the traveling many do...it all needs to get packed tight

....but they're expensive...I like yours better for engine building
