There is a 6"wide trim board is rotten. But only six inches is bad, the rest is okay.

The problem is cutting the rotten piece out. Part of the trim wood fits under a metal covering. A circular saw will not work. I have a reciprocal saw too but that vibrates a lot.

Do that have a narrow saw, that can get under the metal??

I have the same problem, A Multimaster type tool could work great, Rockwell emailed me an offer for theirs at about $110.
Pry wood out a little to expose nail if possible, and cut flush.
Here's one:

I wonder if it will reach to all of the nails. May have to cut down wood close to the metal, maybe rip boad down, then the reach could be increased.

I would suugest that same tool. Dreml makes a version, some have variable speens. Fein also makes them but a complete set up can run $399. That metal is likely your drip edge is can be pried up and hammered back in place.

If you have a Harbor Freight store go there to get the tool. $40.00 with blades

I bought a couple for the guys trucks Works well for us.

21 let me know how long/well they work. I have not had good experiences with HF

No problem Bal. I basically do the numbers on tools being keepers or throw aways. When I started I went to the rental company's I already knew and talked with them to find out what tool line they rented and held up. I figured they are the bean counters of cost/lasting/replacement.

I buy a lot of half and half. So far the harbor freight tool is panning out

Here is the most interesting tool study I ever did. I had a brick pointing job grinding All the joints out. Building was 70' high and 175' long .
The grinders I started with was
Milwaukee
Bosch
Dewalt.

The New Dewalt heavy duty grinder only lasted 2 days. I got a replacement and that lasted 5 hrs. It was still smoking when I took it back to HD. By chance A Dewalt rep was there that day and said there's a home owners Dewlat called Quantum Pro and its not in HD. He also took my grinder and was going to have his people look at it. . HD. Didn't carry it and said check Kmart. I bought two they were cheap.

Believe it or not they lasted through half the job. I went to get more and they stopped caring them. Shucks... Never saw them since

Used a small 12"compass saw. Drip a small hole first

21, I hear you. I could buy from them for a once in a year specialty tool not used often, like my Dreml Multimaster. Only used it twice in 6 months and probably could have gone HF. For my drill/driver I got to got higher like Makita or Bosch.

I bought the Dremel MultiMaster when I was installing hardwood floors in my house. I used it to cut the door jambs and it worked great! I have used it many times since then... it truly is a handy tool.

Last month I used it to cut out a 1-foot piece of 1x4 fascia board on my garage that was rotten. I gently removed the drip edge, used a speed square to get a straight line and whipped out the Multimaster. I got a perfectly straight cut in about a minute. The tool was certainly worth the $100 I spent at Lowe's.

Hi bal. It would be hard to list all the tools I bought at HF.
My standard HF shopping.
Hose repair coupl
Lime safety vest
Knee pads
Air chucks/quic coup.
Ear protectors
Work gloves
Safety glass's ( bigge)
Funnels
Lots of shovels My guys run over then with dumps or loader Lean shovel againist truck move truck.
Etc.
Their chainsaw blade sharpener worked wonderfully, so did their $19 bat drill. A coil roofing nailer.
The best tool I ever had was one that blew out and I lay that on a porch stoop while working downtown inside a re hap and we take bets on how long it will sit there before its stolen. Never had one last a day yet.. I had a tire that I found a free sign on in a yard and thought it would fit my daughters car and no go. Last week I left it by some garages I own and it was gone the next day. Just trying to keep the system going. Now if I can get my garbage bag to do that Id save...
