Scratch Built P Sport Hydro from CAD

Trying to figure out how I got this deep into boats. Never ever been this deep.

That's what she said !

Nothing like coming home smelling like a campfire.

Tried something different. I thought I could cut 1/4" for the center frame, but the curve of the laser is just too much when you get that thick and the kerf was near 0.30mm anyhow. I'm just going to just glue (2) 1/8"pcs.

Who is doing your cutting for you and what is the working area of their table? I have some ideas...

I was up at techshop last Saturday. One of my friends is a member. Table is only 18" long.

Shooter, I have the info for a kit cutter company that has been doing all my stuff for the past few years. They have a large (48") laser cutting bed and specialize in RC (and other art deco stuff). They are very resonable in price. I had a 48" Mono cut by them for $80 and .21 size rigger for $65.

[Shooter]

Thanks Sean. Are those prices including the wood? Or just the service?

I lied by the way, the table at techshop is actually 24" x 18", so it's a little longer than I stated above. Table is still too small to do the outside stringers, but that's about it. Everything else fits (inside axial stringers fit just barely on a diagonal)

I ran a kerf test last night after work to get the slots dialed in. I'm just about ready to start cutting for real.

Shooter that price was with the wood. Waiting to see how she comes out.

It would be cool if you could design this hull to use the stock UL-1 hatch and nose cone.

I am actually leaning towards the UL-1 at this point because I'm running out of time!! I will have to get a hold of a stock one to get measurements. The only one I had was cut-up during the Whip 20 project.

You're right! That IS a great deal!

Limited by the size of the laser cutting table, I've decided to finger joint the longest pcs. The finger joint will be placed at a frame support location so the joint shouldn't suffer strength wise. It might even be stronger once it is epoxied!

At lunch today, I went through several iterations of adjusting for kerf on the joint.

I'm hoping to cut everything by the end of the week and start framing this up over the weekend.

I fitted the sponson pcs together last night. Overall this went quite well. Slot widths all fit nicely, but I never adjusted for the depth. A couple tweaks and I should be good to go.

The original tub width was 170mm. I don't have a UL-1 canopy to measure, but the tower specs are 165mm. I will narrow the tub by 5mm to accomodate the UL-1 canopy. I have access to a really nice vacuum former now, so if I get time, I'll make something similar to the UL-1. You can't beat those mirrors and exhaust stacks though! They look awesome. Kudos to aquacraft.

pete ----think i have the ul1 nose piece downstairs someplace. going to look for it now,you can use it if you want----john

[Shooter]

Oh man, I just made fun of you in another thread 'speed of destruction', and now you offer some help! A true brother! Yeah, I could definitely use the nose.....let me know how much you want for it....and if you can find the hatch, please measure the width! Thanks!

[detox]

My original hatch measures 166 mm wide and 443 mm long. You can also use recessed area on UL hull to get measurements.

[Shooter]

Thanks! One thing I'm worried about is the solid pc of wood in the front. This boat is a lot thicker than the whip/UL-1, so getting it sized down to the UL-1 nose width is going to be a challenge.
