Re: Project: LoBoy Custom
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.
Parted the top off to use.
Turned to final shape.
Drilled to connect to aluminum flange. One component down.
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.

Re: Project: LoBoy Custom
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.
Turned the extension tubes from some scrap 3"OD x 2"ID thick wall steel tube.
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.
Ala band saw.
Lots of figuring, marking, securing and tacking later.

Re: Project: LoBoy Custom
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.
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.
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.
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.

Re: Project: LoBoy Custom
Another solid day at the LCB. Finished the welding on the dutchman and did a finish grind.
Primed up.
Next slid the tranny/transfer back in place and put on the new hubs/ext's.
Then threw on the Model A rims/tires. Felt good, real good.
That called for a fancy cold one!

Re: Project: LoBoy Custom
We attacked the outer flange today.
Raw material 7.75" OD x 2.25" ID. One inch thick aluminum.
Graphics.
Reality.
Front/back.
As they relate to the center hub.
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.

Re: Project: LoBoy Custom
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.
Couple 2"OD x 3" Long 316SS blanks. These were bored to the size to accept shouldered bushings that will ride on stock spindles.
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.
Then after it was pressed in with my old manual arbor press.
After that chucked up, and turned with some chamfered shoulders to dress them a bit.
Then oil impregnated shouldered bronze bushings were pressed into each end. Center hub sub-assembly complete.
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.
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.
