Scratch type 17 project begins

Yes it was impressive to see a Type XVII and a Type 212 (constructed from of all things 8 inch sewer pipe) strapped to the roof rack on top a Jetta

Well guys it's going well.

Well guys it's going well. First I enlarged the plans and formers.

Then printed them out and using 3M 77 attached the formers to press board and cut them out on a scroll saw.

Tomorrow I will start wire cutting the sections for the hull from blue foam. More tomorrow.

Well I goot all the wire cutting done yesterday and now I'm filling and sanding before I glass the two halves.

More to come. Here's some pictures.

man, you got that master

man, you got that master out pretty quickly. used a hot wire tool, eh?

looks good so far. Please keep posting th pics...it's nice to have "visual" accompanying the project.

I will again soon. I

Sam.

I will again soon. I haven't been posting much as I have to upload to my server and then provide a link here. I'm about to start glassing the hull next.

If that is of interest to anyone I'd be glad to put up the blow by blow details of how this is done but most of the model builders here on SC seem to know their way around the block and I wouldn't want to bore anyone too much.

Thanks for the kind words Sam!

Nice work Steve ! Please

Nice work Steve ! Please post all the construction pics you can,Its nice seeing one scratch built and hows its done for the benefit of us newbees.

Regards Kent.

Kent. Thanks a bunch. what

Kent. Thanks a bunch. what i'm going to do here is copy my posts from EZone and drop them here with the pics.

It's just not easy on this site to do a quick post each step as I have to upload all the pictures to my server and then link it here.


Waiting for more spackel to dry and then one final sand and it's glassing time. It will be cooler tonight in my hot garage too.

Here's some tools of the trade for those of you trying to learn how to do this crazy stuff.

West Systems epoxy is readily available at most hobby stores. It's pretty cheap compared to some brands out there. Strong. Sand well and stands the test of time and 100 mph against a runway. LOL! I know because I built many a jet that did just that and they were repaired and flown again.

I'm using the fast cat here but they have a slow too. both give you plenty of working time and they next day it's ready to go.

The glass I picked up at the hobby store too. I was to lazy to drive to burbank and get it cheaper off the bolt but I got a 2 yard X 50 inch piece of 3.6 oz. for about 25 dollars. More than enough to glass this hull with a few layers.

I'll show the glassing process next.

Should have posted these two

Should have posted these two first as I had thought I did.

It's far better than balsa fill. 6 bucks won't even get you a samll can at the LHS. This stuff sands better and finer then any I've used. 6 bucks and you get this big old can! Sands exactly the same as the foam which means no ridging.

Steve

Not much to show but this tool is really smoothing out nicely. "One more sanding pass and it's ready to glass. Then the final tweaking will begin.

What I've done so far is to sand and fill each side on a flat surface up against the side view. Now I've put the two together to check alignment is true and trued all that up. Sail is just on there for looks. We'll get to that later.

Hope all this makes sense. One thing I've failed to point out is that you must use sanding sponges on the blue foam. Straight sand paper will not work and will really tear some big holes in the foam right when you thing you got it where you want it, you'll have to fill again.

At the local hardware store you'll fine these. They work great. Use what they call the sand blaster for the big stuff. Then 80 grit and 120. That's fine enough because you will just glass it after that.

More later kids,

Steve

Now we move on to

Now we move on to glassing the hull halves. First thing is to make sure the halves are clean and free of particles.

Next you need to lift the halves up off the table. I used some blue foam scrap that I know is even thickness and level. I tacked them on with a bit of 3M 77 so they can be removed later in the process.

Then use the hull halves as a guide cut to layers each side of you glass cloth.
Then lightly spray the foam with 3M 77. Do not go heavy or it will eat the foam! You just need enough to get the glass to lay smooth and conform to your tool.

Starting at the tip and holding the other end up with your hand smooth it down so you don't get any winkles with the other hand. Then repeat this process with the other layer. Be sure to spay and coat of 3M 77 on the first layer of glass.

Be sure to trim each layer of glass even to the edge of the hull with a pair of scissors. Any over hang can later be flat sanded away easy.

Now you’re ready to mix epoxy and soak the cloth. That's next as soon as my garage cools off a bit.

And here's the hull parts

And here's the hull parts all glassed up. They will have to sit to tomorrow at which time I can flat sand off the flash. Then start the long proccess of spot putty and primer until it's perfect.

After that I'll move on to detailing it and marking those darn vent holes. Oh boy.

Very nice Steve! http://www.subcommittee.com/forum/icon_smile.gif

As you

Very nice Steve!

As you suggested with your last comments, most people think this is the tough part.
Ask Matt Thor or David Merriman or anone else that makes models. I bet doing the scribing for seams, hatches, limber holes, etc. is where the rubber meets the road

It just takes LOTS of

It just takes LOTS of time and patience. Spend the time up front making templates for everthing that you can. It will save you a lot of time and do overs...
