I need a new rotary...

Yup!

This weekend, a fellow member of the KYC asked me to look at the gel coat dullness on his 1988 SeaRay, 29 foot.

I went down today and did a small test spot, used the "A" of the ABC to remove the surface oxidation, then using a 19.2 right angle drill and some pads, tested out how deep the oxidation was really down.

Yeah, the little drill didn't do what was really needed, but showed me how deep the oxidation was.

Did a another test spot without the "A" and would take twice as long to cut the oxidation off.

He wants me to do it as soon as the boat is out of the water in a month or so.

Guess what, the old Milwaukee comes out for the heavy work and compounding, then the DeWalt with a lambs wools for the final polishing.

Gave him a "rough estimate" for down to 3 inches below the "scum" line, 30 hours plus.

Gonna do some heavy work, get out the big guns.

No reason to use a Dual Action, unless I wished to make it 50+ hour job.

I don't really want to do the work, too old, but at least it will be the storage area, under cover and can work for 3 or 4 hours a day, and then take off.

Can't turn down $30 an hour on my terms.

Why do you think using "A" helps break down the old gel coat? I have someone that swears using 15% ammonia sprayed on will just melt off the old gel oxidation, difficultly is finding 15%.



Cheers,

PS> My vote is to figure out what is wrong with the makita, I bet is just the brushes, I've replaced mine twice....it runs like a champ afterwards. I've also replaced the amarture it was cheaper than buying a new rotary too. Until I can find a lightweight rotary with the sustained torque of the makita I'm not changing.....boats are tough on rotary machines.



Cheers again,

GREG
 
Still reckon the Makita is the best rotary. I change brushes every few months to ensure performance and love to jewel with it and remove peel with it too



I've got two makita's with a dynabrade 61375 and an 85

ours are 240volt as well so even more deadly than the 110 version. they twist like a v8 engine getting some loud pedal
 
Don't "think "A" removes old gel coat", KNOW it aids in removal of oxidized gel coat, which is evidenced by the color of dead gel being in the water that goes on the ground. We discovered this fact years ago.



With the big old rotary, this will be a piece of cake, just that I am 68 and nothing is as easy as when younger.

May hire a young guy or gal to help on this one, teach them the tricks of working gel coat, etc.
