Building a Spectra G, need to get some tools

[surfanarchist]

I'm going to need to buy the tools to do the fan run out and balance. Can you all recommend a dial indicator with base and a balancer that would do this job?

For balancing I've seen the videos of using ice on either end of a mounting fixture as balancer and I think that's pretty slick but I would then still need a fixture to hold the fan. Any thoughts on what I could use for that?

Thanks,

Wayne

Go to Harbor Freight and buy a dial indicator and their magnetic base stand. It will set you back about $25, but it is worth every penny.

Thanks Lou,

That's exactly what I did.

I thought a dial indicatoe was not needed on the spectra. I watched the build videos and John Garst said it was not necessary.

It you have a keen eye you can look at the fan and pull the starter through with no spark plug and see if its wobbling or not. Once you're found the position where it doesn't wobble by the naked eye, I believe its darn well good enough. If you want to be picky, you can whip out your dial indicator. :-)

The point is, if its wobbling to your eye then I'd consider it not good enough.

I used the dial indicator and in just about any position I placed the fan it ran very true. Hard to imagine this was nessesary. Mine veried by about .004 of an inch with no adjustment.
