I was planning on using a perfectly good running old craftsman ROS until I went to order discs. 4.5” are hard to find much less adheasives. The pad is held on by 4 screws and the pad conversions I have seen use 3, I would have to modify it. The conversion kit is around 30 bucks.

I am leaning toward having to buy a new sander. I usually prefer corded stuff. As an old guy who remembers the days of battery memory, leaking, etc etc, I have avoided battery driven tools. However, sanding seems to be a very delicate and moving type of activity and I wonder how useful it would be to have no cord.

I am also leaning toward the only cheap purchase I have made so far, A HF Bauer ROS.

Thanks for any insight into ROS.

yeah time to upgrade to a 5”,and go hook and stay corded,the extra weight of the batteries would make it more tiring than it already is plus a lot more money than you may want to invest.personally i use a mirka sander with sanding screens light weight and very effiecient but at around 600 not in everyones budget.

I don’t have a lot of experience with HF power tools… But, I’ve been less than impressed. There are a lot fo things I will buy at HF (including the dust collector I picked up a couple of days ago)

I’d rather spend just a few bucks more and grab a Ridgid or Kobalt, or get a Dewalt. I had a few Ridgid Sanders for years. They have performed in a commercial environment without fault. I have two 5” and a 6”.... I’m very happy with all three.

Ask 3 people and you’ll get 6 different answers… when it should have been 9… each one will tell you,
  • What they had.
  • What they bought to replace what they had.
  • And what they usually don’t tell you is… What they should’ve bought instead of what they bought to replace what they had.

pottzy’s recommendation of a Mirka is a top notch suggestion albeit a tad shekel heavy, however, I swear by my ROTEX (as well as swear at anything to do with that four lettered work) with somewhat more additional shekels… but I won’t say anything as I’ve already used up 2 suggestions.

So finally, what I will definitely recommend is to get one with good dust extraction and switch to Abranet (or similar hook & loop brand) discs, if you haven’t already… and I’m sure you haven’t as they don’t make 114.3mm (4.5”) Abranet discs.

Used hook & loop, with a bit of life left in them, can always be repurposed.

I wouldn’t touch any power tool from harbor freight. Not even a dust collector. Sockets and some have been good. I just picked up sander new pads for my Porter Cable 4” sq sander. If the sander you have works, convert to the 5” pad. I still use adhesive, they are cheaper than H & L.

Most conversions don’t cover the mount style of this old crafstman. I figured by the time I paid for the parts on such an old unit I might as well buy a new one. What is your source for adheasive, and if I converted I might as well go H&L right? It appears the adheasives , especially the 4.5”, are on their way out if not already gone. If I could find 4.5” adheasive 8 hole I would still use it, grit selection as well as material type is nearly non existent.

And thanks to all of you I decided Dewalt would be my probable choice.

Thanks for all the suggestions

Why not use 5”? It only sticks out 1/4” on each side.

They will probably fray and they will also block my vision a little of what I am sanding. I won’t be able to see the edge.

Mirka has plenty of 5” psa discs. I would think you could drill 3 mounting holes very easily.

Have your say...
