Hi Daz looking good mate,i can see what Cobus is talking about but i agree you dont need to use gelcoat.A trick ive used is to run a bead of clay arround that seam line to seal and also make it a slight (tiny) concave shape this makes for a nice smooth edge.Another good way is to use sheet wax on the whole flange area but its expensive.Or you could also try this wax and run some of this round that join and use a filleting tool same as with clay.Either way im sure youll do a good job as allways.

Hi cobus
Understand what you saying and appreciate it not planning to much yet main thing is get it moulded and 1st 1 out will be just plain white finish and get it tested
Ill do 2 coats of tooling gelcoat so will wetsand it back also which will finish the flanges off

cheers mart thats the stuff i already got

Finally started moulding this project
Got the hatch moulded and polished up
Also filled the small gaps round parting board and added locating pegs
Hoping to mould main hull in the next couple of days

F1madness

Well finally getting there
Topdeck is now moulded just needs trimming and will add some wood to back it up ,just gotta leave it now for a week or so to fully cure before splitting and prep the bottom for moulding

F1madness

Made 1st hatch for this build,only thin layup to break in the mould but also 1st time test fit and check clearances round the engine ,fits nice and clearance is not an an issue so pretty happy








Also now moulded the bottom of this build,fingers crossed releases ok in a week or so ,then wont be long before laying up and pulling the 1st hull

F1madness

Having really good day today and very happy
Released the 48" X-cat moulds even the plug/hull came out on 1 piece lol
Ill spend a couple days now wet sanding and polish them all up

F1madness

Got them all wetsanded and polished up ready to start waxing
Hopefully layup 1st hull next week

F1madness

Layed up 1st hull and joined just leave it few days now to cure,hopefully will release ok and ill start building it up ready for testing

Just placed engine and exhaust in hull while still in moulds so while letting it cure I can make a start on the stringers and transom plate and check clearances










Modified the exhaust to get a better tune length

F1madness

Moulded new hatch monday and released today ,started trimming it up using original build, fits nice
pretty happy so far

Hesco Racing

I know you guys may not have exposed exhaust have you consider moving the motor back and having the radio box in front of it with the tune pipe running forward and exiting through the deck? Had a guy here do it and although it looked funny the thing went like stink. You can then run a normal header.

Hmmm interesting idea Cobus ,never thought of that hehe
Might have to look into that

How did you trim it so flush with the mold? I assumed you popped it out and had some sort of jig setup to help get it flush?

F1madness

Hi espressoo
used a stanley blade ,very carefully and at the right angle just as the FG goes green state of curing
dont need to remove it from mould to do it

espressoo

Wow, so you just use a box cutter as the FG is curing? That's brilliant and saves a lot of FG dust in the workshop. Do you cut it to the edge of the mold and is there any shrinkage of the hull during the curing process?

F1madness

yes bud ,its the the inbetween of to soft an cured
catch it just right trims dead easy anf use the flange/edge carefully holding the blade at the right angle so it doesnt damage the mould
ot had much shrinkage on smaller versions ,this is the 1st one of these but so far so good

Looking great, been watching on the dock, now here
Are stringers generally added after or during main layup ?
Please post plenty of pics when doing seam

F1madness

Cheers wetneck
Stringers can be added either or after ,iv done a few after no problems ,plan is once released the hull and sorted placement of everything for CG ill finish the stringers then make templates,that way when i layup another hull they will be installed while still in the mould
Seam is already done and joined just waiting to release it now ,problem have to be pretty quick when joining them like this ,but ill try and get pics next time round
