I have some concrete repair to do and I am considering using a Skill HD77
worm gear circular saw and diamond blade to remove the old concrete. Does
this seem like a good approach? Any experience with this approach.

Depends on how much you will be cutting. Keep in mind the typical saw is
made to cut a couple of 2 x 4's and maybe a sheet of plywood and then it
sits for a while to stay cool. If you are cutting a long strip you can burn
out a saw in a few feet to maybe 20 feet. Give it a rest requently. I've
seen two saw go in one day from abuse. One did maybe 15 feet, the other a
bit more, but the idiot using them never stopped ntil it was too late.


Anyone
have alternative ideas? I don't won't to go the rental approach because I
have a lot of small applications that I will be doing over many weekends
and
don't won't the expense of repeated rentals.

If you have little luck with your saw, talk tot he rental place. Explain
why you don't want to rent, but would be willing to talk if you could get
some sort of discount for multiple uses. This works better with the local
hardware store than Home Depot.


I assume that I will have to supplement the sawing process with hand cold
chisel work to completely remove the concrete, is that correct?

Another advantage of renting. The big machines have larger blades for
deeper cuts.
