New Millscott project

[PugetDude]

Press and a set of slip rolls to re-form the bearings? I'm guessing braze the two halves together and clean the ring up on the lathe?

Got the hub rough cut today.
10"x .365W
Also started cutting some bronze for bearings, between the body and hub.
The material I have is 7-3/4OD x .350W
With the bronze being smaller in diameter than needed, I'll have to make them in two segments and reform them.

Will The bronze tolerate reshaping that far???

I'll use the hub as a form to reshape them.
They will be screwed to the hub, so I'll wedge and clamp them in the hub as I work around drilling and tapping.
I believe they won't need brazed, with being screwed to the hub.
Then haul them to a friends shop for turning, as I don't have a lathe, that is capable.

Yes, there is only about 1-1/8" difference in bend radius

Sounds like a plan-you using bronze or brass bolts?

 

[royce]

Yes,

Not worried about them during machining? With brass or bronze you could drill and tap all the way through and not worry about depth or tapping blind holes.

They will be through tapped and the screws will fall short of the bore

 

[royce]

Got the bearings formed today
The material was reluctant to bend under clamp pressure, so resorted to the diacro.
They are fitting up nicely.

 

[royce]

First bearing segment flanged up.

 

[PugetDude]

In the homestretch now Royce!

 

[Bears Fan]

Engineering and machining at it finest

 

[royce]

Finished fastening the bearings.
Got the body, hub and rear plate loaded up to be turned.

 

[royce]

Hub bored and faced, body turned.
Now to start on attaching axles to the hub.

Looks good- how big was the lathe your friend used to bore and turn it?

 

[royce]

Thanks, I don't know exactly, but he did mention it being powered with a 10 hp motor.
He had me to do it, under his guidance.
I had a blast and learned a fair bit, in the process.

 

[PugetDude]

I miss having access to our company shop since I semi-retired and moved. Still vaccillating on buying a bigger lathe; my little 6-18 Atlas really isn't big enough...

 

[royce]

Cut some doublers for the hub, opened them up in the press, to match ID to OD.
They will have flats cut, to screw the pivot lock plates to.

 

[royce]

Flattened the top of the doubler, ready to tap 4 more fasteners for the lock plate.
Also turned and tapped two 1-3/8" x 2-3/4" stub axles that will press into the hub and be welded on the inside of the hub

 

[royce]

Another .035 to go and it'll be ready to flop and repeat.

 

[royce]

Both axle mounts bored and started on a rotation brake

 

[RoninB4]

You've got a Moore rotab too? Tooling envy here.

 

[royce]

Finished the brake mounting plate and cut a window for the shoe

 

[PugetDude]

Nice machining job on the clamp pocket.
What size is that destaco clamp?

Thanks Puget,
1300 pound clamp

 

[royce]

Tapped a 3/4-16 port for a positive rotation stop, I don't believe it will be needed, but is there in case.

 

[RivennHewn]

Dang. Lots to catch up on.

I’ve got nothing to add but drool.

 

[royce]

Also finished up the rotation brake today

Thanks Riv, getting closer

 

[royce]

Got the pivot lock plates flame cut today

 

[Bears Fan]

It amazes me the size of your projects and the material used, your work and engineering skills are at a whole other level

 

[Jayman17]

Not to mention the fact that you seem to have all the material you need in your own private
boneyard. Very impressive project Royce, can’t wait to see it all put together

Made some headway on the pivot lock plates today

 

[royce]

Finished up the lock plates today.

 

[royce]

Ears bored for bearings and cam lock.
Also cut sleeves for cam lock bolts

 

[royce]

Fastened bronze brake pads for the pivot brake, also fastened attachment plates for a frame cross member, to the lower ears

 

[royce]

Ears welded to the tubes and capped.
Nice to finally see the frame in 3D

 

[WoodsTruck]

I just hate when people walk on the drafting table with dirty boots.

Nice work.

 

[tarbellb]

The scale of all this is bonkers

Anxiously awaiting to see (and understand) the final product
