I've got a bunch of those boxes, great for all the small fastener sizes. I've found the cheapest good ones are at the fishing tackle aisles in the sporting goods stores - lots of variety of size combinations. I write in the fastener size with a fine tip permanant marker. Not very permanant, a little alcohol (not the drinking kind, that would be a waste! ) on a tissue cleans it off when I want to change it.

Never thought of the fishing stuff aisle. I will have to check it out.


Dave those look expensive with all the individual little boxes. The trays I showed are not as good for travel but my project aint going nowhere. Much cheaper, but still not cheap.

I'm down with that Steve....They're top quality and all, but man are they proud of them!....

When I bought my first 2 of those RSC boxes....the pair was $56.....

The price seems to have dropped a bit over the years

Some honey do's today, and then back in the shop....I'm going to work out the cutting of the main drive gear so I have it when Eric is done with the crank pins

Should be interesting

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?

Mike

Correction!!      I spoke with Cletus, and he did take the pin out of the bag for quench.

Dave,
Harbor Freight has several of those kinds of storage solutions for a pretty reasonable price.  The fishing tackle boxes Chriss is talking about are usually made by Plano.  HFs are not nearly as nice, but they're good enough (I've got a bunch of both) and they're less than half the price of the Plano.

They also have something kind of like your previous picture.  Again, I'm sure it's quite a step down in quality, but it's only $6, and I'm betting it would hold parts.

I wouldn’t call that a Joe Pie tap holder.  I made one at least 5 years ago after seeing a post that Marv made.  I’d call it a Marv tap holder.

OK   Some progress this week...no where near enough, but I've had to work the weekend, and late all last week, so it is what it is.

I have all the material I need for the Crankshaft and the connecting rods.    Cletus delivered my crank pins, right where I asked them to be at  52 Rc.  and as so tempted as I was , I've avoided pressing one in yet.   I need to lap and polish them first.

For the crank
I need an assembly fixture to align the second crank at least close to the first.   that may be made up with a 123 block...
I need to make a fixture to hold a crank section while I finish machine the B side crank.   
I need to machine the center drive gear.   I have the cutters and a cutter arbor.
I need to machine the crank end bell shaft sections....easy peasy...

Connecting rods
I need to bore them to size
I need to fixture them on the bores
I need to profile them to shape

Big end bearings.
I have the material....it should be straight forward.

I was able to get some organizers at Horror Fright...I bought them out!    Nice to have a place to put things and it's amazing how many parts I'm into already

I should have some time later in the week...and I'll take advantage of that.

I have found these boxes work well, the adjustable bins help a great deal..

Some progress photos!    I could not help but put one crank section together, and wow I was worried about nothing!   The procedure is thus.  Make a guide block so you can start to press the pin home squarely.   It's just a block with a close fitting hole that matches the crank pin.   Press the pin home into the A side crank, which is a finished part.  .  Take off the block and put aside.  Line up the raw machined crank side B and tap onto the crank pin lightly (.0015 to .002 press fit on a 7mm pin).  Set the finished side down and check the two crank disks for alignment with a square.  Tap the raw one around until it lines up on both crank disks.   Then press the second disk home to the appropriate crankpin inside width 0.520"....and it's on     next step is to machine the second web bearing diameter in situ to fit the 25 mm bore ball bearing and to appropriate overall length.  I'll need to make a fixture to hold side A concentric while I turn side B.    Not that hard at all Mike.

[crueby]

Nice!
 

[Kim]

Must feel good to get your process verified by the first good part!   

Dave, how are you guaranteeing the 0.520" spacing?  Do you have a gauge block or something that you're using to set between them as you do the press-fit?

Kim

Great to see the progress.  Sometimes the 'hard' stuff isn't as hard when you get into it.  Looks great Dave.
