ML Boatworks PX335 build/ instructions. For use with the PX300, QX400 O/B Tunnels

[Mike Luszcz]

PX300/NX300 AND QX400 SPONSON PICS. THESE ALL BUILD THE SAME AS THE PX335 SPONSONS, BUT THE SECONDARY RIDE PAD WIDTH DOES VARY, AND IS EXPLAINED IN THE FULL INSTRUCTIONS I AM WORKING ON.

Well, due to taking new build orders again (first time in over a year I guess), I have got the old assembly line ramping up. I have some more kits arriving possibly today, so things are about to get real in the ole sweat shop! haha. Hereare the sponsons for Buddy Lowes NX300, Wayne Johnstones PX300, and My QX400 test hull. More will start soon, Mike

 

[Mike Luszcz]

Finishing up 3 pairs of sponsons. Center sections start tonight!

How do u do it with so little dust man!?

 

[Mike Luszcz]

I actually have one of those electric yard blowers I will run in the garage and blow away what I can, or use my compressor blower to clean stuff. I spend more time cleaning than building it seems! Still not clean enough.

NX300 NITRO CENTER SECTION BUILD STARTS HERE. NX300 AND PX300 SPONSONS START ABOVE, AND BUILD THE SAME WAY AS THE PX335.

Got to work on Buddys center section this morning as I had a lot of calls to take last night, so not much got done. This is the NX300 center section. I still have to slide in the 1/8" sticks before gluing starts, but the center took me 5 minutes to dry fit! Pretty simple and slick! Mike

 

[Mike Luszcz]

OK, NX300 center section build. First, start by dry fitting parts like the above pictures just to get use to the parts. Then, set up your center like below:

Now glue your inner and outer engine well frames together:

Then glue the layers of the transom like this:

Now, go back to the dryfitted center, and start running your basswood sticks down the center section:

 

[Mike Luszcz]

All 4 basswood sticks should look like this when cut to length:

With everything above still just dry fitted, dry fit in your engine well plates:

 

[Mike Luszcz]

Now glue in this part first towards the front:

Slip in the transom plate, then start CA'ing all the parts you have installed, and be sure things are square and vertical. Use a square block where possible to keep the outside of the center section at 90 degrees:

Glue in your nosing blocks at the front during this time as well:

These pics stepped forward a little, but after all the lower sticks, and frames are glued in, then you can run the upper 4 basswood sticks and CA them in as well. This is where I am at right now. I will now be epoxying the insides of the center and sponsons, adding foam for floatation, and gluing on top decks.

More done this weekend. I got the center on the QX400 done, got the PX300 and NX300 centers ready for top deck, got the first coat of gel on the QX400/NX400 and NX350 cowling plug done, and got the NX400 nitro mod 7.5 size hull design finished..only two tunnel designs left to finish! Mike

 

[Mike Luszcz]

Got the QX400 sponsons finished and center bonded over the last two days, along with the centers done for the PX and NX 300's.

Mock up for the removable servo tray. I have a Savox TG servo I will ultimately be using.

Rear cover and dowel for the motor wiring to go thru:

 

[Mike Luszcz]

And got the PX and NX 300 center sections finished. Sponson decking tonight:

 

[Mike Luszcz]

Cowling plug for the 35" and 39" hulls is done and ready for compounding and waxing, then mold. Duratec is awesome. It has made plug building so much easier!

Check out my outboard cowling project too! Its a thread here in the outboard forum:

 

[Buddy Lowe]

looking gooooood

 

[Mike Luszcz]

looking gooooood

Buddy, I hope you saw the nitro 300 hull in this build is yours! Mike

 

[Mike Luszcz]

Buddys hull parts are built, and ready for bonding the center to the sponsons, and I plan to deck Waynes px300 tonight. Getting close! Mike

I managed to get some stuff done this weekend to the PX and NX300's. Sponson tops are on, boats are epoxied, and made the NX300 radio box before I went to work this morning. The NX365, NX400 and QX400 cowling plug is in the waxing stage now, and will be ready to make a mold this week! Mike

 

[Mike Luszcz]

Got the 36.5" Nitro, and 39.5" FE & Nitro cowling plug finished, and started the mold layup. I love this tooling resin, wets out mat with ease and doesn't build up heat like regular polyester resin. I still have about 4 more layers of mat to add, and some wood blocking, and it will be done. Also got Buddys NX300 sanded and ready for primer, and Waynes hull got two cowlings laid up last night as well! Wife is out of town, so I can work as late as I want! haha

 

[Chris Dixon]

I've read this thread so many time that I should be able to build a nx300 with my eyes closed......err or maybe not....lol

 

[Mike Luszcz]

And even if you can't find it here, I have sent you a picture text or called to get you guys back in line on the build! I expect your buddy's 300 to be in the water soon!
