Hi,

I'm new here and would really appreciate any and all help. I am a diy'er around the house but have come up with something I''m unfamiliar with but think a router would be the answer.

I'm installing a new dishwasher and (don't ask) but the previous owners did some crazy things. Anyway, I have a need to remove 1/2" from the 1" plywood under the countertop. I can not remove the countertop. I have an exposed edge to work with. The previous owners, somehow, did 1/3 of the job I need to finish now but don't know how they did it.

My 'thought' is that I could use a compact router with a straight bit and slowly cut the 1/2" away strip by strip with a straight bit.

Am I crazy?

Thanks for reading,
Bruce

Welcome to the forums Bruce...

for what reason isn't fitting...
is it just the edge lip of the counter top getting in your way???
cutting the counter top would be the absolute last way to get the DW to fit and not a good plan..

can you adjust the unit's levelers any???
cut away the floor...
can you raise the cabs or raise the front of the counter top.. insert the DW abd set the cabs back down...



BTW... a tad crazy is a plus around here...

That sounds like a plan, one thing you have to watch for is that there is no fasteners,i.e. screws/nails driven down from the top into the rail you want to cut. If you hit one with a router bit the least damage will be ruin the bit.

A jig saw might be better. You would have to temporarily build out the lip you are going to leave, to be flush with the front of the counter edge and follow that as a guide to trim the front of the cabinet.

@Herb Stoops...

I see it as he's trying to mill a ''pocket'' in the bottom of the counter top to accept the DW...
1'' thick ''plywood'' CT's are a bit unusual...

You are probably right , I was thinking that the cabinet had a rail supporting the counter at the DW opening. I have ran across that when they used a face frame and the dishwasher was installed after everything was done and even with the adjustable feet all the way up was too high to slide into the opening. Also was caused with the addition of underlayment in remodels or thicker hardwood floors.

Thanks for the welcome.

The opening is 1/2" too short. With the granite top I'd prefer not to move it. The original owners must have had a similar issue as they cut out 1/2" of the front of the granite and, somehow, removed the plywood about a third of the way back.

Not being familiar with routers wasn't sure if this was a common/typical use but I guess it's similar to making a groove in wood I'm just making a huge groove.

I would agree but that seems to be what is there. The think that messed up the original owners are a few things. The house has infloor heating and they re-did it by pouring 2" of concrete on the original floor. Then they put in the cabinet bases and then the put in the subfloor but not under the cabinets (not how I would have don't it) and then laid a wood floor on top of the subfloor. whew.

Anyway, not sure why they put 1" of wood on top of the cabinet bases but they did. Did I mention that these were the same people who put in a stove vent with no venting outside (not a recirc unit either).

Being unfamiliar with routers in general I wasn't sure if this was a proper and safe use of them.

They already did this and cut a 1/2 out of the front of the granite and the first 10" of the wood under the countertop.

The other problem is I will only be able to get within 3" or so of the edges with a compact router. Those 3" will be interesting as well.

Chisel or use an oscillating multi tool. Alternatively forget the dishwasher and build more drawers or another box with shelves in it's space. Another option: a storage space for a mobile work centre with cutting block top.

Welcome, Bruce...

Might plunge and cross cuts with a multitool do this...plunge then cut out a "row" then repeat?

The best tool to do this is the multi tool. You can pick up a cheap one at Harbor Freight for about $15 dollars. These are great tools and can do things that no other tool can. Once you have used it a few times you will want to get a better one.

I own a Fein Multimaster and would agree that the semi-circular blade would slice through the wood base/flooring without too much difficulty, apart from you being prone and in an awkward position. Just have to hope the neither the floorboard nor sub-floor base were glued down but then even if that is the case, once your perimeter lines are cut, you can lever the middle out, without finesse!

Identify

I think it would be more helpful to those trying to help you, if you could identify what the material actually is. I suggest that you chisel a chunk out and take it to someone more knowlegable if you are not sure. How tools excel is based on the material.

After drawing up the plans for our new kitchen, I mentioned to my wife that we had forgotten the dishwasher. She just smiled and said
" no we didn't". We installed a pullout drawer for two trash cans, one for trash and one for recyclables. Guess who is the dish washer?

I'm going to be odd man out here. Get a counter top contractor in to remove the existing counter top, add build-up to the cab. tops, and re-install the counter tops. Or take Stick's advice re the low profile D.W.
Adding the build -up layer is what wasn't done first time around. Going to cost? Yes. But again, as Stick suggested, anything else is is going to be a royal p.i.t.a.
Ruining the granite edge will haunt you forever, if I understood what's happening correctly.

I'm for the low profile DW. Will save a lot of grief and aggravation, and a few dollars.

Very much a possibility. I'm just not sure how much 'control' I'd have. I really only want to plane down 1/2" from under the counter. I feel I need to be pretty accurate.

It's not the clearest picture but might help people visualize what I'm doing. Again, this is under the counter and not on the floor.

Thanks.
