Sanding with the G100 DA

[Hannibal]

I wouldlike to put my DA to work to sand a few projects. I have used the Porter Cable Random Orbital sandr before, and I think this G100 is basically the same thing. Are there 6 1/2" sanding pads that I can use to veclro and sand with my DA?
Thanks

You'll have to do a search, but read up on Mikes Refinishing an Old Desk thread. It might say what he used.

The G100 is the same machine as a Porter-Cable 7224, 7335 or 7336. What differentiates one from another is the backing plate and counterweight (and that Meg's has a lifetime warranty).

Booth hook&loop and PSA (sticky backed) backing plates in 5" and 6" diameters are available for it from Porter-Cable and other abrasives suppliers (it uses an industry standard backing plate mounting). Abrasive disks are available from numerous suppliers in 5", 6", hook&loop, PSA, with dust collection holes and without.

Parts and accessories are available through many suppliers that handle Porter-Cable tools as well as Porter-Cable service centers.

Here's the desk thread.

I have seen the porter cable pads. They only go to 220 grit. I was thinking of sanding my 1977 F150 with it Heres a pic:

I wouldnt go all the way down to the metal, just enough to get out the rough spots. I had a body man fix all the dents (had a lady give me a parking lot dent though). It has been primered 2 years ago, I never got around to finishing it, well, I want to resand, primer, and shoot a single stage paint on it. It will be my first paint job. I have a 3hp, 90psi@3.4cfm air compressor. It will be a backyard paintjob. I may convert the garage into a temporary booth with plenty of drop cloths and sheets (its a leased house). I was hoping to find some 400 and 800 grit pads. I would start with the 220 though. Is this a reasonable expectation I have?

EDIT: Unless you think I can use some professional meguiar's products to make this paint like new!!
Where the rust is on the hood, the primer is very thin there, The old paint has already been removed. The original lead based paint still remains and makes a good foundation for applying primer I am told.

Not surprising on the Porter-Cable disks, they're meant for woodworking.

I've never used Porter-Cable brand abrasive disks. (I never use my G100 for sanding but even if I did I wouldn't bother with PC brand disks.) As with their polishing pads, they merely sell them for retailer/customer convenience, not because they're particularly useful. I generally use Klingspor abrasives for woodworking.

For paintwork I would recommend abrasive disks from Mirka, Norton, 3M or Klingspor. I have Mirka disks up to #4000 myself.

Try your local PBE store. They'll have automotive finishing abrasive disks. They'll have matching backing plates too (in case their disks don't work with the plate you have now).

Ok, Thanks!! I use the PC pads in woodworking. Thats a complete 15x45 woodworking shop behind the ford.
I have thought of backing my ford inside it to paint it

I really like how the DA removes surface defects quickly with wood, while leaving a finish ready to be stained!! In my case I am hoping for a finish that would be ready for paint!

PS I was mainly looking for some sanding disks that would work on the 6" DA backing pad, but in an automotive grade. I will look at the brands you mentioned.

Hey, Hannibal, I just worked with the electric DA for the first time a couple nights ago. Helping a friend paint prep his vehicle in his garage. That Porter Cable he bought is a nice tool!

He has a hook and loop backing plate and the range of sand papers on the shelf. The other pc mentions very good products and suggestions. You can get 3, 5, 6, and 8" in virtually any grit you'll need to sand.

Your project as a whole sounds reasonable. Wish I was closer...would enjoy helping on that one...well, once I'm done with the friend's here.

Yeah maybe you can show me how to use the Lathe!! (its a huge industrial strength Delta)

My step dad moved out of country and left me an entire woodshop. He was just a hobbyist but man he has truckloads of stuff. I have huge solid blocks of oak, maple, cherry, mahogany and ithers that he gave me. He was going to turn wooden bowls with them. He made an entire living room set also. it wasnt that bad either!!

I tried to turn the lathe on one night because there is a partially completed bowl hooked up to it, so I laid a long sharp wood gouge to it and WHAM!!! It flew out of my hands, I turned it off and walked of like nothing happened ( )
The wood chisels for the lather are rather extensive.

I have boxes of "Woodturner Magazine" to help me, but WHo has time for that stuff when your constantly on MOL?

On a serious note, WHere can I get 6" Hook and Loop (that means velcro right) sanding pads in 400-1000 grit?

[the other pc]

I haven’t tried my hand at turning yet but I’m up for trying it. In theory the key to keeping the gouge from flying is to set the rest up close to the piece (stop and reposition often) and take your cut at an angle that gives you plenty of leverage. Maybe we can start with something a little less intimidating, pens perhaps.

You should have no trouble finding multiple sizes and grits of automotive finishing abrasive disks (not to mention Meg's pro products) at your local PBE store (a.k.a. auto paint shop).
