Question about front wheel hub assembly

I am now building the front wheels - is there any reason to wait for the front axle to arrive BEFORE gluing the hubs ? Are there any crucial tolerances that could not be fixed if I have already glued the hubs ? Thanks very much - all wheel building tips and tricks are welcome !!

Hi

As long as the bushings are in and the hub plates are centred you will not have any problem.
I left my bushings slightly out and centred up the plates.

Watch the thickness of the paint as this can bind up on the axle shoulder.

Thank you very much for that info.

Personally I would wait until I had the axle, I made the mistake of just loctiting a set of bushes in once and then found the tolerance allowed one to be slightly twisted to the other. After that I would loctite the bushes and immediately fit the shaft to line up the bushes in the outer hub while the loctite went off.

Thanks Steve - I had already stuck one outer bush into a wheel — I will now wait till I get the axle to be certain that it all fits, before fitting and loctiting the other 3- I appreciate both replies . Thanks.

OK - I received the front axle and all bushes are now in. Thanks for the advice.

Regarding the 6mm pins that go through the retaining collars - I have found that they are a fraction off vertical when the axle is on, so they rub against the edge of the hub and cannot be hammered in. My plan is to use a suitable diameter stainless steel split pin to retain the wheels - it will be hidden under the outer cover anyway.

The retaining pin is held in place by the outer cover so not enough room to accommodate the head of a split pin.
I encountered the same problem with my showman's and the solution was to file a flat on the inside edge of the supplied retaining pin, and file a little off the collars on the wheel side.
I also pop marked all the parts so they always get fitted/oriented as a set.

Thanks Simon - I hadn’t realised that - your plan sounds like the way to go.

Here are my wheels - now in undercoat - I will do the top coat soon, when the weather gets a bit warmer.
I managed to sort out the pins by filing a flat on them. Thanks to Simon C for that tip.

Just adding this picture to the thread, as I have now put the topcoats on the front wheels.



Lining still to be done - but I need to practice a bit first...

Here are the front wheels after I lined them - they need some varnish and then they will be mounted on the front axle….
