Re: Windmill Tower Punch

I dont often use it up on a tower. Usually setting a stub, there is an old head to remove so I am setting up the hoist anyway. Lay mill and tower down, chop the top, set the stub, put on new head and reset everything. That is the easiest and safest. I have used it twice in the air, once because it would have been difficult to lay the tower down because of the anchor construction and other when I had help. When I did it myself, I tethered the punch off the sand line of the truck at the height I needed to work.
My Enerpac hand pump is made out of very light weight material and comes in at 9#. A 700 ft lb 20V Dewalt weighs 6# to run that monitor punch. The stinking import punch is the heavy part.
Hougen Ogura electro hydro punches are nice and you can now get them cordless. They are lots of dollars. Of course now you can get them import but only as 115V , cost is around $300.
The hex drive Milwaukee titanium shockwave drill bits in a 20V brushless Dewalt 1/4 impact is probably the fastest for putting in 3/8 holes, Drilling with an impact doesnt sound workable but it does work very well. If you are binding the bit in the impact, it just slows down and hammers. Chuck doesnt slip and you dont break bits
It comes down to what you like to use and what money you want to spend to get the job done.
Jerry, when punching two layers with hydraulic punch, you need to vise grip on each side of the punch. The hydraulic punches dont have a strong retract so you dont want it to bind after punching.
