Scratchbuilding USCGC DUANE 1943

ARH · Post by **ARH** » Sat May 26, 2007 1:46 pm

Well Dave , remember STAR PERSEUS, that was the very first time , after that, I cast the hull for my 7ft -4 inch SS NORRIX which stands in the RIX offices in HULL.
After that I cast my hull for my 7ft HMS BRYONY also HMT RESOLVE, all these models had my own cast fibra glass hulls.

I went back to plank on frame for USS VERMONT, USS NORTH CAROLINA, and HMS IRON DUKE.

Then as you say, I reversed the trend because I needed to save space inside the model, I built USS MOFFETT and now USCGC DUANE.

Hi Ron,

In apparence, you don't install motors for shafts(?)

Hi Guys, Having filled the frame work on Moffett with polystyrene, I wanted to try a new material , OASIS it is used with dried flowers, cuts easy, not alot of mess, and reasonalble in price, a full box cost �9-00 or $18.00.

It comes in small slabs 9x3x4 inches 20 in a box.

I marked off the length of the piece I needed, slot it in place and marked out the curve, took it out and trimmed to shape.

Glued in place with PVA white glue, note the piece is 1/4 inch lower than the rib section, this is for the finishing plaster.

Second section cut and glued in place, all sections were filled in along both side of the hull.

enjoy. ARH

Using oasis as an underlying base for plaster sounds a bit dangerous to me.

I have a certain lady "friend" who is a professional florist. She uses, as all florists do, oasis for arangments with fresh flowers since oasis has an incredible ability to suck up and hold a lot of water, giving the flowers an ample supply of water for several days. Since wet plaster contains water, the oasis might absorb the water from the plaster to the externt that the plaster does not cure properly. I have no personal experience from this, but if I were you I would do a small test with plaster on a scrap piece of oasis before comitting to doing the full hull. Just in case...

There was no problem with water being absorbed, it went on a treat.

When you mix plaster you put an amount of water in the bucket and add the powder till you have a stiffish paste, not runny, so there is not a lot for the OASIS to absorb.

Yo Ron Lad,
I've been looking at your build so far and all I can say is 'slow down', you make the rest of us look like tortoises with you the hare.

That 'Oasis', where did you get it from? I've used some other kind of gubbins used for dried flowers and it was messy, crumbled and did not cut or sand very well. It was green in colour.

Jose, I will be using the same company as I did with Moffett, but the 2 x 5/51,s I will have to build myself.

Howie, I believe the green is softer, the sister -in -law got it from her favourite flower shop, he sold her a box full, and said he would take back what I did not use, but I will be keeping it, for future projects,

Good to hear! I was beginning to be a bit worried, didn't want to see you suffer a set-back.

Morning Ron,

Something is up as I acknowledged your post re the 'Oasis' foam yesterday but I don't see it. Anyway, thanks for the info I'll keep my eyes open for it.

Two posts up Howie.

do you need any.

Hi Guys, I mixed my plaster to a slightly creamy but not runny mix, putting a small amount of water in a bucket and adding the board finish plaster gradually, and stiring with a stick.

The mix was then troweled on and left to stiffen.

Stern shot .

Bow shot.

After about 1 hour the plaster beginnes to harden off, this is the time to get the paint brush and water on the plaster,also use the trowel.

You can see the difference in the finish surface.

The following day I turned over the hull and filled it with the Oasis.

A close up of the bow.

Also the stern.

Both sides are now plastered.

enjoy ARH

Indeed a very interesting and (for me) new approach.

Mornin' Ron Lad,
Interesting method of making a plug. I did a similar exercise about 25 years ago using plaster, old bits of brick (on the inside!) to make a 'Cossack' hull. Needless to say the plug could not be moved. The mould that came off was a bit rough as it was the first (and last) I tried. It was usable until a friend of mine fouled it up.

The rate you're going with this you'll have it ready for July (Kingsbury).
Slow down please. Take a rest. You make the rest of us look as if we're not trying, which some of us are (think about that). Apart from that Ron, more power to your elbow. I like it already!

Howie, I will not be at Kingsbury or the next meeting, I will be on Lake Garda for 10 days, with a trip to Vennice, dates 6th - 15th July.

Ron--model looking excellent!!!

If you are in Venice--do 3 things:
1)spend the money--and it is plenty!--on a Gondola Trip--you only do it once

2)Visit the maritime museum-open only in the mornigs till 2.00

3) take a varnished wooden watertaxi for your transfer back to teh airport-
leave your hotel via the 'water door' and blast across the lagoon --its a priceless experience!

Hi Guys, When the plaster had hardened, I gave it a coat of wall tile adhesive, this sets very hard in 24 hours, to get a good finish I painted it with a brush and some water,

Looking from above you can still see the outlines of the rib shapes underneath.

Bow

Stern

I was going to use baking foil to cover the hull as in the Moffett Build, but the CIC had put it away somewhere,

, while looking for alternatives I came across some matierial my son had used 10 years ago, must have been when he built his MOONLIGHT.
Poly Lustre, a mold releasing agent, why I had not tried this before I do not know.

The hull was given a thin coat , wiping it on with a cloth, the tile adhesive absorbed the thin coat.

A second coat was appied and left till the next day.

enjoy, ARH
