Built a hot tub kit with deck for my wife to exercise in, 6 ft in diameter and 5.5 ft deep. I even used a garage door opener to lift the lid. Works slick but took awhile.
Built the 2 tanks out of stainless - many thanks to Jim Langan who is a Midlana beta builder for most of the stainless and MUCH technical (read - welding!) help and advice. The stock MR2 pump and sender fit right into the design of the left tank. The steel lines from the pump had to be shortened, so I used the double flaring tool to create a bubble on the cut ends for hose retention. I used a piece of .125" 304 stainless for the mounting the pump, sender, filler and vent tubes. One picture shows the .75" stainless tubes used for fuel transfer and surge. The design of the baffles and tubes attempts to route the fuel to the fuel pump pickup under cornering loads. Check out the pictures. I calculate 9 gallons plus about a gallon for "air".
I fought the Ebrake!! I finally made a couple of levers to get everything to work. Modified the MR2 ebrake handle and mounted it between the seats in front of the dash. I have to reach thru the passenger side to use it.
Bought a sheet of .050" 5052 for misc panels. The top of the tub including an access panel are now formed, as is the front bulkhead. The fiberglass piece seals the area of the steering column around the u-joint that goes thru the tub.
I am working on a dash layout - just ideas so far. Also experimenting with a windshield design. I will try to incorporate 2 front "quarter" pieces to help with the air flow. Thinking of a .75" to 1" dia. hoop around the windshield with 2 braces down to the middle roll bar braces for the "quarter" windows to mount. Wondering about making 1/4 round 2" radius fiberglass fairings to connect the windshield to the quarter windows and possibly fairing the top of the windshield with them. Bikini top from there back to the rear roll bar?
Finished the headers and collector. The collector ends into a 3" u-bend that tapers to a 2.25" muffler! Hope it works!! The idea is that the collector ends into the 3" tube that the headers see as an open exhaust - that is the theory anyway. See auto exhaust science article by David Vizard.
http://www.popularhotrodding.com/engine ... index.htmlI wanted to incorporate the cruise control from the MR2 (ROAD TRIP!!). Finally figured out that the water neck for the heater at the rear of the head would make an excellent mounting area. A .125" blade of alum. sandwiched between the neck and head with a tab bracing to the bolt side of the neck would work. The stock MR2 link will even work. I added on to the stock Yamaha ITB throttle cable mount for a ball end to attach the link. Mounted a GM throttle position sensor (tps) to the other end of the ITB's for the Megasquirt.
The subframes finally received their sandblasting. Lightly sanded and primered them. Sprayed with a catalyzed enamel. Only problem was I used the catalyst from a urethane taint!! Back to sandblast, used an epoxy primer and then sprayed with another quart of enamel that was catalyzed properly. There went over $100. I can now start assembling (rivet and adhesive) the tub!
