Hi Glenn,as we talked about earlier regarding building up the Mercury Cat again with my Zen7.
The cs23 i have or did have on the Apache and the cat stuck out a far bit,which i think looked odd,i am thinking of getting a shorter one to replace,so could flog you the pipe you want?
speak to you later in email....

Brod, I have a cs24 not doing much if that is what you are looking for....

I am fortunate enough to build at my place of work although that has it's own problems.

Glenn 10/10 for the photos it's just the mood lighting that needs work..

Your not wrong about the room under the motor ,mines the same on the rockett .Not much room in the engine bay on mine at all i supose yours will be the same ?,can be a pain sometimes especially when your used to running bigger boats.Wont have as much of a problem with the glass versions i supose,ill post some pics soon of my hydro plug on a new thread i widened the opening to give more room for better access to the motor,carb etc.Still working out the canopy design but the hull is done just need to get it ready for some primer.Was hoping to get the rockett wet but its too dam cold and i bet the lakes frozen

Ian,well what i have is a 2 boat build up.i have 1 cs23a,stainless finish.
In the near process of the rebuild Mercury Cat,which you've probably seen on RCU.The cs23a was a bit too long for it.
I'm also also ready to hunt for 2 indentical pipes for a inline MTI cat build,not sure which ones yet though.
Is your cs23 shorter than the cs23a?

sorry Glenn,for talking about my boats

on your thread, but it kinda involves your hunt for a pipe too.

Talking about pipes im thinking of trying this one 570 mm long might fit nice in a hydro,i can get it for a good price but they sell for about £80 normally .

brodjack · « **Reply #55 on:** February 07, 2009, 05:56:08 pm »

that looks similar to that black pipe running in Jacks boat,mart?
if so,should be good.

Yea they do look similar mate ,i think theyre very similar to the cs23a from Dave but alluminium.

570mm he said Brod - which is the same as the CS23 near enough. (22 1/2")

I am happy to take your CS 23 off you Brod.

Some more progress, slow going this epoxying lumps of wood. You were right Ian - it gets frustrating!!

Apologes for the sensitive on the misuse of a tool in the next shot - it was all I had to hand when fumbling to get a clamp into place!!

#

The starboard sponson skinned complete. Needs sanding to finish.

The port side sponson trip edge. As you can see, this sponson has a different profile to the starboard side.

Another shot of the same, like the lighting?

So we have some progress. Next job is to complete port side, sand them all off to finished profiles. Then hardware mounting. At last, something that is not wood!!

You wont dislike wood so much when your wood whip is kicking the glass versions backside theyre a good deal faster than the glass ones

Nice thing with wood Glenn, keep it tidy on the outside and then using stain, epoxy and polishing you will get a finish far better than any paint job. Makes all the hassle worth while.

Good point Ian have a look at this beauty might give you some ideas Glenn,mixture of paint and stain looks stunning

Hi Mart,

not sure I know why the wooden ones are faster than the glass ones, I am thinking that because they have been out longer, the boats have had a couple years of set up on them which makes 'em quicker. I too had heard they are faster, just don't like it when I don't know the reason behind things.

I have seen the Sanchez build, in fact I am using it for some photographic guidance in places, it is a very well put together model, not convinced on the colour scheme myself.

Good point on the finish Ian, although I not sure how I am going to finish it, there are a few places that are going to need some covering!!

Might try to go for simulated GRP look - just to save embarrasment at the lake if anyone finds out I have some sticks glued together with an engine bolted on!!

I think the main reason the glass ones are faster is they can be lighter by quite some way,im sure its possible to make a glass one as light but you would lose some strength unless you used epoxy etc.For the price of a wood one compaired to epoxy there would be a massive price difference id suspect so thats probably the main reason behind it.Wood is quite a lot stiffer than standard glass (poly) and if built straight is a great material to use and it wont flex as much as a glass hull maybe that is another factor in why glass hydros and riggers are faster than glass ones.

Eh?
I thought you said wood was faster than glass?
Glass is faster than glass.?
Think maybe your finally losin' it mate!

Which straight away reinforces my point that epoxy glass is one of the better materials for building with. But you at the time said Polyester glass was better as it was cheaper Martin and good enough for model boats..... I think if you factor in time to the equation, then Epoxy glass (or better epoxy carbon / kevlar) is not that dear. If this wooden whip where to include my time at even £20 / hour, then the labour alone in it would be in the region of £200. I know it is a hobby so somewhat irrelevant to price time, but puts perspective into the cost of purchased hulls ready to fit out.

I think weight might be one issue, but I think in time you will see some Whiplash GV's doing OK in the racing - also remmeber they have not been out long so not too many races have taken place with them yet.

Time will tell.

Will get the final skin on the sponson tonight then that's one job done.

Glenn ive never said polyester glass is better than epoxy,what i said was to me epoxy is not cost effective for the boats i make so polyester is better suited to my uses .Yes polyester boats are fine for most uses.There are more companys using it than epoxy for sure,reason been cost and demand.There just isnt the high demand for most companys to use epoxy.Im sure the glass whips will do well racing but as has been said many times a good wood one will beat a good glass one even Blazer himself will admit that.Where glass has the advantage is in they can produce them faster and cheaper than they can a wood one.

I reckon I could build one in glass a whole lot quicker too, no sticks to glue on place building one of them!!

Far more satisfaction in building something yourself..... it'll be worth the trouble when you see it flying across the water...

Building method reflects the market, looking at the US, where polyester is king, guys are changing boats left, rigt and centre and the price structure allows that. Europeans seem to build to last more and are willing to pay for a hull with inbuilt longevity, ie epoxy.
Last but not least are those that enjoy the building process and they are willing to lay down time on wooden construction. Wooden boats are however limited in their design as you can only get wood to do certain things without special equipment and processes.

Wood can't be all that bad the Mosquito (http://www.aviation-history.com/dehavilland/mosquito.html) was a wood construction..... although that used one of these special techniques in it's constructionhttp://www.aviation-history.com/theory/plywood.htm.

Enough of this discussion, we want more PICS, well I do at least

I know theres a lot of guys building epoxy hulls on your side of the channel Ian but i don't know of any in the UK who actually make any epoxy hulls themselves although some do sell them I'm not sure where they're actually made.Ill let you get on with it Glenn i wont say have fun as it seems your not convinced wood is your friend.Maybe you will change your mind when you run it,for me building is more than half the fun of this hobby but to each their own.
