Other Finally machined some carb spacers

[demolition_x]

i was gonna make a few of these for myself i was wondering how tall the spacers need to be so the stock 44 box clears the head?

 

[demolition_x]

Here is the design I came up with...

I just need the height so I can order material. :thinking:

 

[#ZERO]

I'm diggin' your design and o-rings too. :woot:

If you make them a least 1.375" tall they'll work well.

I think you should make them in a few different heights for taller billet cylinders, AM intakes etc.

 

[demolition_x]

so that will clear x cylinders with an ada head?

im also gonna try to come up with something for aftermarket carbs, like brap jacks and novi's.

Here's a little trick I use all the time at work when people send me pictures of damage on airplanes and don't give me any details.

Get one measurement you know is accurate in real life. Then measure it on the screen.
The measurement of the blue line on my 44mm carb is 10.6mm. In the picture, (on my screen) the measurement is 11.9mm. Now the measurement of the yellow line in the picture is 35.2mm (on my screen).

10.6/11.9 = x/35.2
Remember algebra? x=31.35mm which is 1.23 inches so factor in some funky eye balling and the real measurement is probably 1.25 inches.

One thought though... The o-ring looks like a good idea but because the spacer is above the carb, it doesn't need to be sealed and even if water were to sit between the spacer and the carb, not enough can leak in to make any noticeable difference. If these are just for you, no biggy... If you plan to sell these, I think the extra cost involved with the added o-rings and extra machining will make these an item that falls into the category of "cool to own but not worth the money".

I thought there was a thread floating around the X about NOT stealing someones design??

You can also zoom so Real life = On Screen, just be carefull that you are measuring things in the same plane and account for camera distortion.

if he's making them to sell - that's one thing.

if he's making them for himself - that's another.

and it's not a carbon copy of the design (like people splashing footholds and tubbies)

 

[SuperJETT]

How many ways could you actually design that piece anyway? 1 big hole, 4 little holes, what more is there to design, plus it's o-ringed, so I say it's a different design yes? Plus, iwith the x-metal saltwater can get inside the bolt holes and not drain, and encourage galvanic corrosion between the aluminum and stainless bolts. I'd rather see an enclosed/sealed design like this one.

Yeah I've done the zoom thing too but usually takes more time that way. I measured this one on the corner to help eliminate camera distortion.

galvanic corrosion between the aluminum and stainless bolts

Yeah that's certainly something that the jetski industry hasn't really caught onto yet. Guess we don't have too many options though. It's either stainless or titanium bolts and titanium would really increase price.

Yes and I can't wait to see some more of your products; you're building some real cool stuff.

He hasn't even posted a price on this product and it might be even cheaper they the x-metal unit. :hitwithrock:

I thought there was a thread floating around the X about NOT stealing someone's design??

How would that be stealing someone design, he's merely improving on the idea and making it better IMO.

Just look how many different flame arrestor adapters there are on the market in different styles and colors.

This is just a spacer between the carb and the oem flame arrestor so it will work with different heads and taller cylinders.

Well said and I have to agree that that cut out on the sides looks like a place for saltwater to penetrate and cause problems.

like i said i am making a set for my self, and possibly another set. none of them will be for sale until i give up jet skiing.

 

[demolition_x]

finally put the time in tonight and made them.

had the 1/16th inch ball end mill break on me the last pass so i have to see if that will seal fine or i will have to make that last pass when another end mill comes in. All that is needed is dash 033 orings and 4 x 1.5 inch bolts.

I might have enough material to make another set if somebody really wants a set. some of the surface has marks on it from holding it in the vice and theres really no way around that, but with some sand paper and mothers polish they come out blinging.

what's the performance beni for using a spacer between carb/flame arrestor?

nice job looks good!

Not for performance. It is so you can fit a Stock Flamer arrester over an aftermarket head.

 

[FyrHazard]

Those look pretty nice! You could probly get away with a rectangular o-ring groove if you want to speed up the machining process. I use the Parker O-ring Handbook at work when I need to use o-rings. There are some formulas for squish room and whatnot.

Just my .02c

Always good to see people improving things

Looks good Rich!
