Looking For Medium

March 15th, 2018

I have been glassing the insides of the hull panels with 5.6 oz fiberglass cloth and West System epoxy.  I predominantly use 205 Fast Hardener which is usable down to 40° F which I typically use around 50 to 60° F.  This last week the temperatures were in the 60’s during the day and dropping to the low 50’s at night.  I wanted a long working time so I could have used the 206 Slow Hardener but that may not cure completely when the temperature drops.  I recently read that you can mix the fast and slow hardeners to get a medium hardener.  I tried this on the rear side panels and after curing for two days I don’t see any issues.  I will give it another 3 to 5 days before I sand it and then I will definitely know if there are any issues.

Final Score: Fishing 0, Boat Ride 1

March 12th, 2018

Fish Taco had her first outing of the season and she performed as great as every.  You may remember that I replace the transom corner knees and the transom center knees this last winter.

I went to Green Peter reservoir, about two hours south of Portland, for Kokanee fishing.  The fishing was very poor but the weather and view were excellent.  I had added pads and power connectors for the downriggers and this was the first time I have tried them out.  The downriggers are mounted the bridge deck about amidship and this turned out to be a good location for them.

I trolled east on the lake and after 3 hours I had a nice run back to the boat ramp doing around 17 knots.  I had a little problem getting the Fish Taco back on the trailer because I had forgotten my boots.  This week I will pack Fish Taco for a crabbing trip which I hope to have better luck.

Friday in the Boat Shop, March 9th

March 10th, 2018

The weather was nice yesterday and I was able to open the shop while working. Mark N. show up and help me cut the fiberglass and peel ply. Later Rick H. showed up to watch the proceedings. Amazingly both had somewhere else to be when time came to epoxy the fiberglass the the side panel.

The process I use for applying fiberglass the the panel is to lay out the fiberglass where it needs to be and smooth it out. I use lead weights to hold it in place. Since the fiberglass cloth can be pulled out of shape there is a lot of smoothing out. I also set out the equipment that I will need: many sets of gloves, paper coffee cups, stirring sticks, squeegee and paint roller with an epoxy tolerant paint roller cover.

I mix up a batch of epoxy; in this case West Systems 105 resin and 205 Fast hardener. The fiberglass I am using is style 3733 5.6oz. X 50″ Fiberglass Cloth. I pour the epoxy over the fiberglass and spread it evenly. I then make up another batch of mixed epoxy and go and see how the previous batch of epoxy has penetrated the fiberglass. I add more epoxy where it is needed and the rest of the epoxy is used on the adjacent dry area. Once the fiberglass looks wet, I use the roller to even it out and move epoxy to a dry area if needed.  I want the fiberglass wet but not too wet and not too dry; if is off I can still make it work but it is work.

The peel ply was cut into squares and once I have an area of coated fiberglass I put the peel ply down and work out any folds or air bubbles. I was asked why I cut the peel ply into squares instead of using it full length and the reason is to make it easier to remove the folds and bubbles. Also working a large piece of peel ply is a lot of effort to flatten out. Sometimes I have stubborn bubbles that just don’t want to work out so I add denatured alcohol to the paper towel and the alcohol breaks down the surface tension and thins the epoxy. The last thing I do is clean up the tools with denatured alcohol and leave the shop before I get any epoxy on me.  The photo shows the finished side panel with fiberglass and peel ply waiting for the epoxy to cure.

The next Friday at the Boat Show is looking to be March 23rd.

Tolman Skiff Build Resumes

March 6th, 2018

After two months of little progress the Tolman build is moving ahead again.  I was sick in January and the garage was too cold to epoxy in February. The bottom panels have been scarfed, the scarfs glued up and the inside of the panels have been glassed.  In the photo I show two rear side panels having the scarfs glued up at the same time.  After the epoxy cures I will glass the inside of the panels and then they will go into storage until they are needed.  The rear side panels are 32 inches wide while the forward side panels are 48 inches wide to account for the sweep of the bow.  The forward side panels are put on the hull, marked, cutout and then glassed on the inside. It is a lot easier to glass the inside of the panel while they are flat.   The outside of the panels will be glassed when the hull is upside down..

Razor Clamming Report at Seaside Oregon for November 3rd, 2017

November 6th, 2017

For the third attempt at Razor clamming in Seaside Oregon the weather was cooperating.   We arrived at the parking lot at the foot of 12th Ave. a little before sunset and were treated to fabulous water colors. 

As were we were heading down to the beach several experienced clammers were leaving with limits of Razor clams.  We were told we should have good luck that evening; unfortunately our luck was spotty.  For about an hour we traipsed down the beach looking for clam show and then backup up for another hour.  When clams were found they were bunched together but the shows were elusive.  I ended up with 7 and 1/2 Razor clams; enough to make clam chowder.

The next and last clamming trip will be on December 1st, weather permitting.  Low tide is -0.15ft at 6:01PM and sunset is at 4:31PM.

Razor Clamming Report at Seaside Oregon for October 20th, 2017

October 23rd, 2017

I made another attempt at Razor clamming in Seaside Oregon.  Low tide was at 9:07 PM so Mike S. and myself left Lake Oswego at 3PM to get out of town before the evening traffic.  The drive to Seaside was uneventful until we arrived at the junction of Hwy 26 and 101 when traffic stropped for about 45 minutes; about every 15 minutes traffic would move and then stop.  Once traffic cleared we did not see the reason for the delay.  It was after 5 PM when we stopped to eat at Tom’s Fish and Chips and had the all you can eat cod fish and chips and the fish was surprisingly good.  After diner we got to the parking lot at the end of 12th Avenue and put our gear on and we were on the beach just before 7 PM.  For the next two hours we walk up and down the beach and never saw a clam show and none of the other clammers had any luck.  The one bright spot was my new LED headlamp.  The Neolight T5 head lamp has five LED’s with 6 settings, 2 18650 Li-Ion rechargeable batteries and is reported to be waterproof but after inspecting it I would say that it is only water resistant.

Razor Clamming Report at Seaside Oregon for October 13th, 2017

October 14th, 2017

I went Razor clamming yesterday and I wanted to let you know how it went.  This is my first Razor clamming trip in almost 50 years and I had a great time.  I left Lake Oswego around noon and arrived at the 12th Ave. parking lot in Seaside just before 2:00PM.  I geared up and headed out to the beach which was a little bit of a walk in soft sand.  Once I was at the wet sand I saw a clam show and had bagged my first clam.  I quickly found another show and had my second clam within 5 minutes  I thought that this was easy so I moved to into the surf line and worked my way south.  For an hour I pounded sand and did not see another show so I gave up and when back to where I started.  Once back I quickly saw a clam show and had my third and final clam.  I just put the clam in my bag when I was overrun by a herd of tourists running into the surf.   The best part was when the father told the kids not to get their clothes wet.

Too much stomping on the beach frightens the clams so they don’t feed and when they don’t feed there are no shows.  It was now just after low tide so I worked my way North to get away from the tourist and getting frustrated I started digging at anything that look like it might be a show; I startled many sand crabs.

I am going to try again this coming Friday, October 20th.  Low tide is at 9:07 PM so I plan to leave Lake Oswego mid-afternoon to avoid the Friday traffic and be at Seaside around 5 PM. I will get something to eat at be at the 12th Ave. parking lot around 6:30.  At 7PM the tide will be 1 ft and at 9 PM it should be at 0ft so I will clam between 7 and 9 PM.  I will let you know how I do on my second Razor clamming trip.

Transom and Stem

October 3rd, 2017

I glued up the transom with the lower doubler; I still need to add the 2×12 and upper doublers.  The two slots cut in the lower doubler are where the stringers will fit into the transom.  I have made the router patterns to cut out the rounded over parts of the transom so I must likely will do that next.  Having the main part of the transom in the correct shape will help when I cut out the 2×12 and upper doublers.

I had a problem with the wood I used for the stem and even though I had cut it and shaped it correctly I need to make a new one.  The stem is glued up from two Alaskan Yellow Cedar 2×4’s about 4 feet long.  I will plane down the blank to be 2-3/4 x 3-1/2.  The glue line will be the center line of the 3-1/2 inch side.  I will cut off the forward corners at 34° and then shape the rest of the stem from there.

A Dilemma

September 26th, 2017

Home Depot delivered the LVL and I-joists today and I started cutting out the stringers.  LVL is Linear Veneer Lumber which is made similar to plywood where the grain of the veneers in plywood are at 90 degrees to each other, in LVL they all run the same direction which gives the beam it strength. I-joists are beams that have LVL on the top and bottom with OSB (oriented strand board) in the middle.  This make a lighter weight beam that will be used for the building frame.

The stringers are made out of the 1-7/8″ x 14″ LVL beam at cut 8 degrees to get two mirror stringers that are 7-1/16 inch tall.  I setup my track saw to cut the 16 foot long beam in half; I had to use all three of my tracks segments for my track saw to allow me to cut the entire length of the beam in one cut.  Once I have made the stringer templates I can continue cutting and shaping the stringers.  I had to clean up the stringers a little because they were not completely straight; there is a slight bend in two directions.  Nothing to adversely affect the boat but I needed to address it now to avoid problems in the future.

I next started working on the transom by marking the outline.  Only lines marked in red get cut and I need to add the angle that the plywood is cut to.  Keeping track of all angles for the cuts can get tricky.  I will do most of the cut with the track saw and then finish up with a jig saw to connect the cuts that make an inside corner.  Some of the corners are rounded and I will rough cut with the jig saw and then make a template for my router to make the fillets and round overs.

Home Depot gave me a big dilemma; I had ordered a 15 foot LVL beam for the stringers so I could build a 20 foot boat.  Home Depot delivered a 16 foot LVL beam so now I could build at 21 foot boat.  The 20 foot boat will barely fit in the garage; how will I fit a 21 foot boat?

Making Templates

September 18th, 2017

I like making template for marking out lines or to use as patterns to trim the material to size.  I drew the temples for the bow-stem on 1/8 Baltic Birch plywood and cut it out on a band-saw.  There is another way to make templates and that is to use either a CNC router or a laser cutter.  Since I don’t have access to a CNC router and I do have access to a laser cutter at Sylvania PCC I decided to draw the shelve and stringer templates in CAD for the laser cutter.  The laser bed is only 18″ x 32 so I had to find a way to connect the smaller pieces to make the larger template.  The template for the stringer show above is just under 8 feet long and consists of 4 segments.  I designed puzzle joints that I will use to glue the segments together.  The laser can do vector cuts, vector lines and raster images.  Text is usually done in raster and so are pictures but raster is slower than vector so cuts through the plywood are always done as a vector.  In the stringer, I added the angle of the cuts to the template so I don’t have to look it up each time.  I will have to transfer the reference lines from the front to the back when I draw out the seconds stringer since they are mirror images of each other.  Below are the segments as they will be cut out.Since there is a common straight edge gluing the segments together will be easy.

The shelf is longer at 170 inches long, just over 14 feet.  The six segments for the stringer will be cut out of two 18″ x 32″ pieces of 1/4 Baltic Birch.  I added reference lines with known points so I when I glue the segments together  can make sure that the shape is correct.

Sylvania PCC has a laser cutting class starting on September 25th, MCH291 Laser Cutting and Eng. Fund.
