Hi guys

Not much work has been done on the boat due to work commitments, but I managed to get some stands built yesterday to take the boat off the trailer. Altough you guys do this regularly, we do not. I cannot even buy stands in SA, so I built my own. Bottom work next, then back on the trailer and motors on.

Cheers!

Those stands are $500 a pop here in landlubberville Minnesota. My Skoota hulls are getting stands built in the next few weeks. Bought a bunch of hardware yesterday for them.

I have to build custom stands that can be used for trailering.

Those stands are nice! All I have ever had was wooden blocks and used 55 gallon drums.

Hi guys, thanks for the comments. I biult these with the following materials:

1. Scaffold base jacks at 700mm long;
2. Pieces of scaffold pipe, I think they are 50mm x 3mm. Steam pipe or high pressure water pipe has thick sidewalls;
3. 60mm x 6mm flatbar.
4. 30mm x 3mm pipe for the leg struts
5. 18mm plywood (transom off-cuts) as a sole on the jackplate top which is 150mm x 150mm x 6mm steel.

Everything was cut to size and mitred by hand (not perfectly done) and stick welded with 3.5mm rods. Safety chains are 8mm. Best of all is all the material cost me about US$110. All scaffold pipe and the base jacks came from a metal recycler at US$70 cents per kg, and the flatbar with the 30mm pipe cost around US$36. I did buy other steel for use as well but these were never used so I will recycle those again. Took me a day from purchasing to final products. I will be honest and say that it was nerve wrecking but she is standing as solid as a brick out-house.

Works can continue safely with good access.

Cheers!

Thank you. It was challenging to figure out how to position everything to get the trailer out, but once I moved the trailer 2m forward wher the tall stands are, I could put tye center stands in. Luckily the point of balance was about 1/4 forward already so I could take out the tall stands and free the trailer.

Cheers!

Hi guys

This might not look like much progress but it was 4 days worth of sanding. A layer of spray paint has been sanded back to reveal the original gelcoat. I am planning on applying a new layer of flowcoat over top and simultaniously repair some old gelcoat damage.

I know all too well the slow progress story as we are fairing the port hull for about a month now!

Good luck! It is gruesome, tiring work! Yours does look good, excellent job!

Hi guys

Work has been progressing very slow due to bad weather and work commitments.......nonetheless I had a surprise when I tried to remove the stainless cover plate around the bow eye......

Some twat decided to use mild steel nuts to secure the eye with and needless to say these rusted away completely. Net end result is cutting the old u-bolt out and replacing it. This however is not the whole story...... The bow eye was sealed extremely badly and the maranti keel stem was rotted away behind it. I had to cut, gouge, file and sand all the old bad wood out, and wait almost 5 days (Eventually I heated the anchor well) for the wood to dry out. I had some offcut maranti available from the keel extension and cut a wedge to size which was resin soaked and dried before installing with epoxy. I finished up with some thickened resin over top and glassed in the front with three layers of 1708. I still need to build the back portion up and will glass with 6 or so layers if 1708 and then add a 300mm x 45mm x 5mm stainless plate on the inside as backplate to reinforce the bow eye......hopefully this will be strong enough.

I used an old panel to do a test run on gelcoat spaying. Keep in mind that the panel was raw CSM and not smoothed out as the hull is. I ended up spraying two layers of gelcoat, thinned 30% with styrene albeit still maintaining a high viscosity, and sprayed with a 2.5mm gravity feed gun at 4bar pressure. I had a better result with the air medium, needle fully opened and pattern adjusted to a medium/narrow flair. The second coat went on better altough not as thick as the first coat. I finished with a light coat of flowcoat sprayed over top. Everything was catalysed at 2% with the temperature around 19°C and himidity at around 69%. The initial layers of gelcoat was left for around 3 hours to tack up before the next layer went down. The flowcoat was sprayed about an hour and a half after the second coat. Unfortunately I do not have a mill guage to determine the thickness but looking at the profile it seems about 1 to 1.5mm. I sanded the little orange peel I had back with 400 wet and progeessively stepped to 1000 wet. I should have sanded out with the 800 and 1000 a bit more but the objective was the technique and not so much the absolute mirror finish. This said however below shows the panel after sanding and then after two coarse compound applications and two polish applications.

I think that my game plan will be to spray the boat one half at a time, meaning port and starboard and then do the transom on its own last.

Cheers till next time!
