Spindles? Don't know what they are.
The hub has a piece of pipe in it 15" long. Same length as the hub. With an I.D. of about 1.98" to 1.99".


At 15" of depth, it seems it would be hard to ream out the entire length.
I am checking into turning the end 19" of length of the axle down to 1.950" on both sides.

Check that bushing in the hub and make sure it isn't tapered. Is the wheel dished?

Spindles of course are the machined end of the axle that fits in the bushing.

The bushing in the hub is a straight pipe. This has been the case with every wheel I have ever purchased. Quite a few at this point.

The wheels are dished.
The axle is a straight piece of 2" round bar.

If there's one thing Houston has a lot of right now, it's oilfield machine shops with not much to do... a 2" x 15" ream would be simple for one that has the right tools. Hauling the wheels over might be a problem though, so turning down the axle may be easier.

For a homebrew option, I've opened tubing ID using a flap sander on a drill extension. Takes a while but doable.

Dang those wheels are huge! Like Zulu’s idea of turning the axles. More meat to work with and probably greater precision.

Question. Why 12 vs 14 spokes?

Here's the pics. this one is 2-1/2" diameter. I would go 1-1/2" tubing and wrap the cloth belt several times to fit the ID of the tube snug. It is an aggressive tool and will remove the amount quickly. It would be nice to have a 2" round for a test fit piece. Good luck in whatever you decide to do.

Before the Civil War, most cannon carriages had 12 spokes.

I'm basically following John Muller's design with this carriage.


Haven't decided what I'm doing yet on the axle problem.

Just found out that 2.5 million people visit the Alamo per year.
In 10 years, over 25 million people will have taken their picture in front of this thing.

Just a suggestion to maybe increase the clearance between axle and bushing to make it a looser fit. The carriage and cannon are likely to sit undisturbed for long periods with chance for moisture to accumulate and rust to build up, possibly rusting the wheel to the axle.

The wheels are dished.


If this is true and the axles are not tapered or bent such that the spokes are not vertical between axle and ground, you will have a problem. This will cause side thrust on the joints at the hubs which will loosen those joints, and moving with the wheels rotating will make things worse.
