|
Hardboard templates are made from the orginal lofting. |
|
|
|
|
|
|
|
|
|
|
|
|
The reference marks are transferred and connected using a batten sprung fair. |
|
|
|
|
|
|
|
|
|
|
|
|
I used finish nails and lead weights to hold the batten. |
|
|
|
|
|
|
|
|
|
|
|
|
The hardboard templates were transferred to the actual marine playwood stock. |
|
|
|
|
|
|
|
|
|
|
|
|
Using a jigsaw I cut close to the line. |
|
|
|
|
|
|
|
|
|
|
|
|
The pattern was then reattached. |
|
|
|
|
|
|
|
|
|
|
|
|
The final cut was with a pattern bit in my largest router. The bearing rides on the hardboard pattern and the bit trims the plywood flush. |
|
|
|
|
|
|
|
|
|
|
|
|
The cut plywood sections are tacked to the strongback. |
|
|
|
|
|
|
|
|
|
|
|
|
Bilge stringers get milled up from 8/4 stock. First planned... |
|
|
|
|
|
|
|
|
|
|
|
|
|
... then ripped on the saw. |
|
|
|
|
|
|
|
|
|
|
|
|
The ends get scarfed and bonded together to create the correct lengths needed. |
|
|
|
|
|
|
|
|
|
|
|
|
Three scarf sections after cleaning up the excess glue. |
|
|
|
|
|
|
|
|
|
|
|
|
The bilge stringer gets bonded to the backbone. |
|
|
|
|
|
|
|
|
|
|
|
|
Doublers are cut for the skeg/keel. |
|
|
|
|
|
|
|
|
|
|
|
|
Cut doublers waiting to be bonded. |
|
|
|
|
|
|
|
|
|
|
|
|
2 of everything, 4 of most. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Epoxy bonds the pieces and ring shank bronze nails are used as well. |
|
|
|
|
|
|
|
|
|
|
|
|
Avoid placing nails in the aft most skeg area since you have to fair a taper here later. |
|
|
|
|
|
|
|
|
|
|
|
|
One side completed. Hull stringers are being glued up at the same time. |
|
|
|
|
|
|
|
|
|
|
|
|
The backbone is flipped over to repeat the process. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Bulkhead guides are bonded in place. |
|
|
|
|
|
|
|
|
|
|
|
|
Fiberglass tape at the butt joint. |
|
|
|
|
|
|
|
|
|
|
|
|
The entire bilge section is well protected with two coats of epoxy. |
|
|
|
|
|
|
|
|
|
|
|
|
The completed backbone was moved off the strong back. |
|
|
|
|
|
|
|
|
|
|
The second on was begun. Most of these parts have already been made so construction is much faster. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Starting the lofting of the bulkheads. |
|
|
|
|
|
|
|
|
|
|
|
|
This is the time to make sure that you have enough width at the bilge stringer... |
|
|
|
|
|
|
|
|
|
|
|
|
Two coats of epoxy on both sides. |
|
|
|
|
|
|
|
|
|
|
|
|
And then I cut them out with a jigsaw. |
|
|
|
|
|
|
|
|
|
|
|
|
|
One lower hulls worth of bulkheads. |
|
|
|
|
|
|
|
|
|
|
|
|
After creating an overhead crossbeam, the finished backbone is prepared for raising. |
|
|
|
|
|
|
|
|
|
|
|
|
A spare couple of vangs provide the mechanical advantage needed. |
|
|
|
|
|
|
|
|
|
|
|
|
Along with a little muscle... |
|
|
|
|
|
|
|
|
|
|
|
|
Note all of the bulkheads are cut out and ready to go |
|
|
|
|
|
|
|
|
|
|
|
|
With the weight supported the stems are positioned and screwed in place to blocks on the strongback. |
|
|
|
|
|
|
|
|
|
|
|
|
The bulkheads are notched in place with their legs attached. Then the weight is slowly released and all of the bulkheads are squared and plumbed to the reference lines. |
|
|
|
|
|
|
|
|
|
|
|
|
Once everything is correct the bulkhead legs are secured to blocks and the stringers are attached. |
|
|
|
|
|
|
|
|
|
|
|
|
The pink blocks are plastic food wrap coated so the epoxy wont stick to them. |
|
|
|
|
|
|
|
|
|
|
|
|
The stringers are mostly done, just the stem bevels remain. |
|
|
|
|
|
|
|
|
|
|
|
|
Beveled, screwed and glued. |
|
|
|
|
|
|
|
|
|
|
|
|
Almost finished, note the extra stringer (the lowest one in this position). |
|
|
|
|
|
|
|
|
|
|
|
|
The hull panel sequence begins. |
|
|
|
|
|
|
|
|
|
|
|
|
The panels are scribed, cut to fit and mounted. |
|
|
|
|
|
|
|
|
|
|
|
|
Note the bevel cut into the bilge stringer. Almost half of it gets removed this close to the ends. |
|
|
|
|
|
|
|
|
|
|
|
|
This far forward the stringer is almost vertical. |
|
|
|
|
|
|
|
|
|
|
|
|
The stringers are marked on the hulls with a pencil line top and bottom. |
|
|
|
|
|
|
|
|
|
|
|
|
Almost finished. Time to remove and coat them with epoxy. |
|
|
|
|
|
|
|
|
|
|
|
|
All on, time to come back off. |
|
|
|
|
|
|
|
|
|
|
|
|
The hull panels get two coats of epoxy on the interior surface after they are fitted and the stringers marked. |
|
|
|
|
|
|
|
|
|
|
|
|
I use a plastic squeege to spread the epoxy and a foam roller to even out the coverage. This gives a nice surface to sand later. |
|
|
|
|
|
|
|
|
|
|
|
|
Coat as many as possible at the same time. |
|
|
|
|
|
|
|
|
|
|
|
|
After they are coated and sanded, they get bonded in place with thickened epoxy and bronze screws. |
|
|
|
|
|
|
|
|
|
|
|
|
This brace is where the butt blocks are bonded in place holding the edges of the plywood fair. |
|
|
|
|
|
|
|
|
|
|
|
|
Screw holes are being filled. |
|
|
|
|
|
|
|
|
|
|
|
|
More screw holes being filled. |
|
|
|
|
|
|
|
|
|
|
|
|
Wrapping up the sanding. Exterior bilge fillet done. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Almost finished with glass work |
|
|
|
|
|
|
|
|
|
|
|
|
Next step is to fill the weave. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Weave filled with microballoons and sanded. |
|
|
|
|
|
|
|
|
|
|
|
|
Setting up the hull turn over. |
|
|
|
|
|
|
|
|
|
|
|
|
Slings set and unscrewed from strongback. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Carpet strips added for padding. |
|
|
|
|
|
|
|
|
|
|
|
|
Taking the weight and raising the hull. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Pausing to wait for assistence. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Rotate! Turned very easily, a complete waste of man and woman power. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Centering on the bulkheads. |
|
|
|
|
|
|
|
|
|
|
|
|
Everyone gets a chance to look over the progress. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Time to prepare for moving off the strongback. |
|
|
|
|
|
|
|
|
|
|
|
|
Post move, we finally can relax. |
|
