Hey, sport's fans! Been a bit, but we're still at it :{_}: So ok, now for some of the good stuff. Metal chips leaving their prior living spaces!

Finally, secured the main components necessary to start machining the front and rear hubs. The front hubs will be made from aluminum, bronze and stainless. The main driving forces there are that I have the pieces available, so I'm working the design backwards from that. The main three components are the aluminum outer flange which will bolt to the Model A rims, the inner stainless sleeve that rides on the spindle, and a bronze adapter to connect the two.

One of the parts we make are called deck boxes. They flush mount to ship/barge/rig walls or floors and allow for valve actuation. They are made of cast magnesium bronze and finish machined. We had a couple go to scrap recently, so I utilized a portion for the hub adapter.

Scrap piece.

Image

Parted the top off to use.

Image

Turned to final shape.

Image

Drilled to connect to aluminum flange. One component down.

Image

For the outer flange I had two scrap pieces of aluminum plate. They measured 1" thick x 8" OD as luck would have it. Turned the OD to 7-3/4" and the ID to 2-1/4" to fit over the adapter nose. This will require a lot more work.

Here's a simple 1/1 scale drawing I did on graph paper. It shows a cross section of the outer flange and adapter. The inner sleeve is not shown yet. Also shown are the 1/2"-20 threaded holes for the lug studs.

Did some more work on the rear hubs as I'm waiting for a machine to open up to attack the fronts again.

These are the inside washers that mate to the original LoBoy hubs.

Image

Turned the extension tubes from some scrap 3"OD x 2"ID thick wall steel tube.

Image

Mocked up with larger washer. With the strengthening fins(5), these puppies are going to be heavy..........heavy's good.

Hey, we're rolling sports' fans. Cut the fins from old machine shipping braces and tacked up.

Raw material.

Image

Ala band saw.

Image

Lots of figuring, marking, securing and tacking later.

Got some good work on the LCB last night. Hit the shop right after work. First order of business was to rotate the final drives 180 degrees. One side slipped on easy, the other required kissing a brass hammer several times. Finished.

Image

Next was addressing the damaged rear frame section on the passenger side. Not only the poorly repaired crack, but the steel was corroded to the point of being to thin to be structurally sound in places.

Image

I'll admit I tried noodling out fixes that were less involved. Wasn't satisfied with any of them long term. My solution was to cut out the bad and replace with good. I had a piece of frame steel that was cut from the frame's front under the radiator that was no longer needed. It was big enough and the same thickness. I also wanted to replace the steel past the existing crack, so as to stop it from recurring. Fastened a jig for a guide and broke out the plasma cutter.

Image

Image

Next the dutchman was cut to shape, drilled and chamfered for welding, Clamped in place and hard tacked. Still needs final welding and some finish shaping, but that's for another night. Overall, a good night's work though.

Another solid day at the LCB. Finished the welding on the dutchman and did a finish grind.

Image

Primed up.

Image

Next slid the tranny/transfer back in place and put on the new hubs/ext's.

Image

Then threw on the Model A rims/tires. Felt good, real good.

Image

Image

That called for a fancy cold one!

We attacked the outer flange today.

Raw material 7.75" OD x 2.25" ID. One inch thick aluminum.

Image

Graphics.

Image

Reality.

Image

Front/back.

Image

As they relate to the center hub.

Image

Next onto a stainless center sleeve that will insert into the brass inside hub. That will ride on the spindle itself. Then the three will be bolted, etc. together to form the hub assembly.

Also, thought some may be interested in a tool I used to get the two layers of paint, primer and rust scale of the original rear hub faces.

It's a Snap-On Crud Thug. I got it a Snap-On box lot I bought from my oldest brother. Bought the box of stuff for the wrenches, and this was included. Probably not made by Snap-On, but this thing works really well. Ran it off an 11 gallon tank compressor, so there was some lag here and there, but still impressive tool.

Interesting that they spelled "coarse" wrong. Neat tool though.

Some more work on said front hubs.

First, took the bronze inner and bored it to size to accept the SS sleeve to be made.

Image

Couple 2"OD x 3" Long 316SS blanks. These were bored to the size to accept shouldered bushings that will ride on stock spindles.

Image

Image

Next, the outer profile of the SS sleeve was turned to size and shape. The OD was turned to .001" over the ID of the Bronze inner hub. This made for a press fit. No other attachment methods will be used.

Here you can see it turned to size.

Image

Then after it was pressed in with my old manual arbor press.

Image

After that chucked up, and turned with some chamfered shoulders to dress them a bit.

Image

Image

Then oil impregnated shouldered bronze bushings were pressed into each end. Center hub sub-assembly complete.

Image

Image

After this the center hub was pressed into the aluminum outer hub. Took two guys hanging on the arbor press handle, but slow and smooth she fell in. Added some 304SS hardware to complete.

Image

Working on making SS studs now. Going to spot weld these crown nuts to these lengths of threaded rod. Maybe on all fours again tonight!

Very nice machine work! You're obviously a very talented machinist.
