- I pulled out my 1/2 inch round over bit for my router, which had a 1/4 inch shank.
Upon installing it into my portable router, I discovered that the bit would not fit through the hole in the plastic base.
I wasn't much larger, maybe an 1/8 inch total, if that much. So, I started the router and proceeded to gently move the bit through the plastic base, so it would protrude out from under the base.
- I then marked the pattern, and cut the bottom off, which angled the bottom like I had wanted.

- As Alfred Hitchcock used to say ... "Good Evening"! Lol.
I unclamped my last glued portion of the sink today.
I then cut a piece of white coroplast, (you know, basically plastic cardboard), and I cut it to fit the inside of my sink pattern.
The I positioned it to fit the angles I wanted.
The bottom of the sink will look something like this, with the drain being installed in the left rear corner, with all the water running to that area.
- Here is a pair of those bent pieces that I put together, so I now have one that is a little more than 10 inches wide, and 3 layers thick.
I guess I should have made the full pattern before gluing any of this together, but this will work just as well.

I was hoping to pull the clamps off over the weekend, but, it should happen tomorrow. navegator wrote:
You can use a steam box to soften the wood in order to bend it, I have used that many times to bend wood, household plywood does not work it disintegrates the glue is water based but marine plywood does work the glue is not water based.

Thanks for the info.- navegatorExplorerYou can use a steam box to soften the wood in order to bend it, I have used that many times to bend wood, household plywood does not work it disintegrates the glue is water based but marine plywood does work the glue is not water based.
navegator - I guess we can relegate this one to the dead pile. Lol.

I have some other pics to post, but I think I'll wait til tomorrow night. navegator wrote:
I know exactly what you are doing, it is a reverse pattern and the fiberglass goes on the outside of the box.
What I am referring to is making the bottom of the sink with rounded corners and the four corners radiused so that there are no 90° areas, also give the bottom a slope towards the drain hole, we have a deep sink in the kitchen with the drain hole in the far right corner and sloped, no water remains in the sink.

Gotcha. I do plan to radius the bottom of the sink, probably after I connect the bottom to the side, and then fiberglass over the top of that.
I also do not want a very square corner at the bottom of the sink.LouLawrence wrote:
Should not be cringe worthy. This "box" is not the sink. This is only the "form" that I am making to glue the sides of the actual sink together. The "sides" of the sink will be glued around, but not to, this form.
No, there was no confusion. We both understood what was the form and what your future intentions are. I am sure it will look good but you will still have a wooden sink covered in fiberglass. With the understanding that you will likely not complete this in my lifetime, I can well understand why you build a wooden sink when you could save a dramatic amount of time by buying a sink of the same basic size and shape.
My mistake.
Find me a sink that is 15" front to back, 22" wide, 8" deep on the right side, 10" deep on the left rear side, with a slope from the right front and right rear to the left rear, and also a slope from the left front to the left rear.
Then, make sure it has a drain in the left rear area for drainage, all for less than $100 and I'll buy it.
This will cost less than $50, although I'll have a bunch of time in it. However, I'll have what I want when I am done.
Am I happy with the speed of this project? - No. I thought July would allow me some extra time to work on it, but, alas, sometimes "compost occurs". That is the politically correct version of "S*** Happens".
What can I tell Ya?- navegatorExplorerI know exactly what you are doing, it is a reverse pattern and the fiberglass goes on the outside of the box.
