Hoglet Brass flywheels less expensive source?

[Vietti]

Considering building the Hoglet. Plans call for two brass flywheels 4' dia OD and .562' thick, ID just under 3". Anyone know of a less expensive alternative than McMaster Carr? Online metals pretty steep too. Perhaps someone has some material left over from their own build.

Make them out of mild steel and paint them. There isn't enough weight difference to affect the way the engine runs. The cost of brass has gone completely insane.

I have been saving cast iron dumbells for flywheels. Do you have a local scrap yard? That's where I would look for things like that.

Hi, whilst I recognise the density of material is different, I made my flywheels of large pipe steel fange with the centre of black strap steel, then chemically blacked them. Still came out as a heavy set of flywheels.

Check ebay, but look for that odd-ball oversize brass or bronze pipe fitting or bushing.

And just an odd thought here, but have you thought about using 4" wide flat stock and making a riveted laminated construction? It would certainly be unique, and very bad A$$ looking, depending on your POV.
