[TowerTalk] Drill motor

[Mike Reublin NF4L]

Thanks Bryan -

My application will be making the tower lie down and sit up, so the load would be a bit different ..... maybe. I talked to a local big name Milwaukee dealer here today. He thought a Super Hawg was a Harley.

I'm looking at wheelchair motors also, and a Fulton KW3000.
