    Well done on the pour Bruce. With my lead I found that a wire brush attachment on angle grinder gave an excellent finish for coating with epoxy. You'll need to fill the odd divot anyway. Epoxy is a great undercoat for painting. As you know...

    Thank you Andrew. It is a great relief to have that melting business out of the way. I hope you're feeling well.

    Very good! What kind of material in keel-bolts do you plan?

    Well done! Although I didn't pour my own 900 lb. keel, I still remember the fun of getting it out of my van and into position by myself. In my case, I put it in place and built the boat on top of it rather then adding it at the end of the build.
    I was born on a wooden boat that I built myself.

    Fredrik - I have 3/8" (9.5 mm) Si Bronze bolts. The inner keel has been drilled where specified at the correct angle. I'm planning on the inner keel holes to serve as a drill guide for the lead.

    Bruce just on the drilling now that you mention it. I found that the lead when being drilled is sort of "sticky". By that i mean it doesn't seem to take much to heat it up and make it gall on the bit. You also need some where for the swarf to go and I found as i drilled deeper it became more of a problem for swarf to travel back up bit. I tried acetone and kerosene and then just plain oil but while helping a little, drilling through 9" of lead still became difficult. I hope your lead being a little smaller wont be as difficult. Oh be sure to back out bit frequently!
    Just a heads up. Good luck

    Thanks for the drilling tips Andrew. I have two long bits for this task - 3/8" and 25/64" bits. The thinking behind using the larger bit was to leave some room for epoxy. Both bits will be dubbed and the smaller 3/8" bit can be used for evacuating the hole. I've noticed that some folks use liquid soap. Which is preferable - soap or oil?

    I covered the inner keel with packing tape, coated the lead keel with thickened epoxy and jacked it into place. It seemed like an easy way to get a good fit.





    All of the bolt hole drilling was done from inside the cabin. There's an oily mess of lead chips on the floor. Mostly, the drilling process was drama free. Once drilled, I dropped the keel and turned it on it's side (much easier said than done) and made the counter bores.



    I'll do a bit of wire brushing and corner shaping before I jack it back into place. All the silicon bronze bolts have been cut to size. However, we're going on vacation so the final mating with have to wait.

    It's been a month since that last pic and I'm still occasionally finding lead bits. Perhaps I've gone a bit mental about finding all the lead remnants. If I can muster the gumption, I may add another epoxy fairing coat prior to painting. All the lead shavings were melted down into one ingot. It weighed 26.6 lbs, coincidentally the identical weight of the lead bricks I used. Glad it's installed and I hope I never have to mess with it again.


    All my Sitka lumber was rough sawn. I got a bit lucky having straight edges. It would have been a challenge for me to straight-line 16 footers.


    It's bad enough getting around my small shop with a boat in it. Putting this spar bench in totally messes up any kind of coherent traffic flow. The laser makes quick-ish work of getting a straight work surface. The extra 2x2s on the sides has served as a sort of shooting board for the tapering and will provide a ledger to clamp to. I ended up using 3 different size boards scarfed to form a 27' board. 23 gauge pin nails helped keep the boards from slipping during glue up and they easily pulled out after the epoxy set.



    This is a box mast so the fore and aft boards (7/8" thick) are tapered both sides for the upper 12'. The mast sides (5/8" thick) are tapered for the same length on one side. The fore and aft boards have rabbets.




    Tomorrow I'll mill and glue up the blocking and experiment with some mast-top crane shapes.

    Spar work took a hiatus while enjoying some fall camping and waiting for a 7/8" round over bit to arrive. That was a big bit to spin in a hand held router. It ended being low drama by slowing the speed way down. There are 3 sections of internal blocking. The blocking was cut and beveled to alleviate a hard transition. The blocking at the top was extended to form a tenon to which the crane was attached.




    The boom is solid and a bit over 9' and is tapered toward each end. The spreaders will receive a copper strip over their tips.

    Through mortises were cut to accomodate 74mm sheaves.

    Nice job! Was the box spar specified on the plans, or did you just not want to mess with birdsmouth? Nice to get the keel job on and done with.

    The finish will be Cetol teak and gloss. The box spar was specified. I've done birdsmouth several times and had no reservations to use it. However, birdsmouth would require many more scarf joints. Furthermore, the mast taper schedule would be more complex with birdsmouth. I'm not aware of a marconi rigged Gartside design that employs birdsmouth spars. The mast weighs about 45 lbs, so it's not particularly light weight. For grins, several months ago I investigated what a carbon fiber mast would cost. I was quoted over $5k (15x the cost of Sitka). Perhaps, I can reduce some weight aloft by using synthetic rigging. I have purchased heat-set dyneema for the backstay. It's a struggle for me to understand how to employ syn. rigging for the remaining shrouds and stays on a trailer sailor where some attention to setup time is required. My build has pretty much followed Gartside's plans religiously. I will probably use the spec'd 3/16" stainless.

    Perhaps how close one gets to a boat before the imperfections jump out is a decent measure of the paint job. There are several areas in this paint job where it's best to take several steps back, but it is what it is. I wish I had the room to use our HVLP sprayer, but the boat is too close to one wall. We rolled and tipped using System 3 water-based LPU. Gartside drew the painting pattern on the lines plan. You'll notice the mast hanging near the boat. The spars have received three coats of Cetol Teak. I'm going to wait a while for the two remaining Cetol gloss coats.

    Much appreciated, but pride is probably not the primary emotion. Mostly I want to get the boat done and start using it. I recently did another hit list. It's sobering to account for all that remains. Devils and details. However, I will make a pitch for the paint. It is supposed to not share the safety related issues normally associated with LPU paints. This paint is fussy regarding temp. and humidity. It dries very fast. Yet a wet edge has to be maintained. However, if the temp. is not too high and the humidity is high, the paint will flow nicely. I rolled small areas and Sue followed with her tipping brush immediately.

    The entire build looks fabulous! Looking forward to see her splashed. Do you know if this particular model has been built before?

    Thank you Fredrik. I believe that this is the first #170. Not a source of comfort - to say the least. It would have been a real asset to leverage off the experience of prior 170 builders. Sue and I still have high hopes that this boat will meet our needs, but perhaps we occupy an unusual niche.

    Have you seen this discussion, maybe something...

    Have you forwarded this thread to Paul? I imagine he'd remind you that about a third of the time, work and perhaps materials remain in the finishing out of details once the hull, deck and cabin furniture are complete.

    Fredrik, I did see that thread. Nice boat for sure. In fact, I have been discussing sail configuration with the sailmaker we will use (Schattauer Sails). As with the rest of the boat, there's little desire to deviate significantly from Paul's plans. There will be no fat head main. I want a standard split backstay (no running backstays). The deviations from the 170 sail plan: There will be one, perhaps two full length battens at the top. The main will be loose-footed. We'll discard (or maybe delay) the installation of a furling setup for the jib, using a simple downhaul instead. The mast head crane design will be modified to accommodate an asymmetrical spinnaker. In total, these are trivial changes in my opinion.

    Thanks Dave. That means a lot coming from someone who has a boat that pretty much defines perfection in my book.
