Building 417 from Plans

[jhippe]

I was home for a day yesterday so got some time in the shop. Started experimenting with coamings. Went to the big box store to pick up some Douglas Fir. Got some clear stock in the 2X4s but they are quite wet -- running 17-22% moisture. So they will need some drying out. In the mean time I will be looking at other sources for dry Douglas Fir or another decent wood.

Trying to get the right reveal and depth to the channel for the gasket. The wider reveal (to the inside of the gasket -- towards the hole) is stronger but I don't want to close off the opening too much...

I am cutting the grooves with a plow plane and then will miter the corners.

In the first photo you can see that the gasket is pinched. Therefore in the second picture I added some reinforcement in the corner so that I could trim the corner to ease the turn which seemed to be a bit helpful.

In the last picture, I have the wider reveal which allows me to ease the corner a bit. Will continue to experiment more when I get home next weekend.

I am outside Toledo, Ohio for work this week so took the opportunity to explore local lumber yards. Found 4/4 Sassafras already milled. Bought a little over 14 board feet. Price was $2.25 a board foot so good price. The wood database http://www.wood-database.com/sassafras/ rates sassafras as durable to very durable with regards to rot resistance and is comparable to Douglas Fir for weight.

I have never worked with Sassafras but am looking forward to it. It has a nice, spicy smell. Will be using for the coamings for the hatches and runners.

After this week I will be off the road and home for about three weeks so looking forward to ramping up the boat building again...

Toledo Ohio.... that's my home town!! Our property was very sandy and Sassafras grew like weeds all over the place. Really nice trees, beautiful colors in the fall, and loved the smell of the roots when we dug them up. Never new they had good rot resistance.

Frustrating day in the shop yesterday. Started working on the coamings. I like the Sassafras. It works easily -- much easier than the white oak and hard maple that I am used to. Dimensioned enough stock for one coaming and then took some time to dial in my plow plane and rabbeting plane.

When this was done, I started cutting the groove for the gasket.

After cutting the groove, I cut a rabbet with the intention of recessing the gasket a bit. My hope here is to allow compression of the gasket when the hatch is installed flush with the bulkhead.

This, again, took some fiddling but eventually I got what I wanted.

My problems began -- or continued -- when I started cutting to size. Geometry and math are not my strong suits so accidentally cut them too large.

No problem, I thought. I will just cut down to a smaller size...

AAAARRRGGGG!!! As Bugs Bunny would say..."What a maroon!"

Oh, well, back to the shop today. Hopefully I will make more parts than mistakes...

Much more success in the shop this morning. Completed two sets of coamings and the backing plates to the hatch covers.

I have decided not to cut the rabbet. I will simply add a spacer to the back of the bulkhead. I think this will be simpler and provide a more precise fit.

Fine work! And again, those are some beautiful tools. Thanks for sharing.

Today I decided to start epoxy coating the parts. I am not able to get them all laid out at once so I think it will be a three or four part sequence ...

First coat applied. Used Silver Tip fast curing epoxy. Rolled and tipped B4, the hatch covers, and the bottom. Everything else just rolled. Now having a cup of tea to wait for the first coat to cure enough to top coat -- hopefully in an hour or so...
