Titanium Motor Mounts?

[nate]

Everyone is doing 3-4mm Carbon cut plates for most of the twin cat's now days, but searching up on Titanium sheets, and has really got me thinking. Is this possible? The thickest sheet of titanium I have found for a reasonable price (15x15 .125-1/8" thick) is $47.99 a sheet.

Is this material hard to cut, shape? Is 1/8" thick enough to support a motor in a sponson?

1/8 thick is over twice as thick as you need. Ti work hardens very easily. It is a very tough metal. Sharp tools, slow cutting speed, and once cutting don't stop. Do a search on the web, you will find helpful tips. Titanium is a super poor heat conductor. Takes alot to heat it up and forever to cool down. You can stick a piece in molten solder for 60-90 seconds pull it out and it will be only warm to touch. 2024 T4 or 7075 .06 thick aluminum would work great depending on design of the mount.

Yes it's hard to cut, and motor mounts would not be a good application. "Thin" is not the goal in twin motor mounts.

Thats why I thought 1/8" would be wayyy too thin...No worries, I just bought a few carbon fiber 3.30mm plates from a composite company.

I agree thin is not the goal. Rigidity and heat dissipation would be the goal while adding as little mass as possible.

Its hard to cut for one. You won't cut it with a band saw. It'll eat the blade. Then your epoxy won't stick to it well so you'll need to drill holes. And good luck with that. You eat up some carbide bits. Its not worth the trouble really. Cf is far superior because of its cost, workability, and easier to bond. You'd be better off with aluminum but I'd rather cf.
