Hey all,
Don't want to start a debate but,
Just a quick question, how much, on average, would it take 3M pads for the slow build?
How many Red, How many Grey??? Or is just one type sufficient??
I plan on priming pretty much all the inside...

And about the wire twister, 6" or 9"?

Any suggestions ???

Many thanks !!!

I used tons of these during the build. I would suggest you get 200 of the "maroon" and 50 of the "blue". If you're really anal like me about smooth edges and use your high speed for everything, you may need even more than that.

I prefer the 9" twisters.

I found a local industrial supply store that stocks the 3M stuff. I've probably gone through a dozen of them on my slow build (fully primed). 200 seems like it would be a lifetime supply!

Thanks Walt & Bruce for your replies.

I realise that it's not that important in the end.

I just don't want to buy in excessive quantities if not needed.

200 seems a lot, I agree...

I'll go for 20 as a first order and see if I need to get to 200.... I found a European distributor and at around 1$ apiece, it won't make that much difference...

Trivial in fact and I apologise for taking up space here and time for you folks!!!

Cheers

Scotchbrite wheel for a 6" bench grinder!

I got one of those when I first started, and have consequently not used more than 5 sheets of the maroon SB, and less than 2 of both the gold (coarse) and the grey (fine). I would never build an aluminum airplane w/o the Scotchbrite wheel ... it has saved uncountable hours.

Thanks Terry for your advice...!!

I will have the ScothBrite wheels!!!

The pads will mostly be used to roughen up interior surfaces prior to priming.

For added speed in doing that, I intend to use a round 3M pad holder attached to a slow turning drill.
