Yeah, I'll experiment ... then post here ... Then EC can copy them in bulk and sell them like hot cakes ...

Dravis, forgot to say center hole drilled at 5mm.
Guessing you could play around with hole diameters to affect the resin flow.
Let me know how they work for you.

Its really cleaned everything up and only needs a small amount of gum to seal.
machined the pipe diameter to 7mm and the bag side at 9mm.

Very clever bit of lathe work there ... excellent idea! My lathe is already running

@ Scott Hi, apart from hot glue, scissors and craft knife everything is from EC. I use filleting wax, green release tape and fluted sign board. You can cut the board with scissors, glue it then tape or wax the joins, id say all these pieces are worth the outlay and although the board has its issues it works well. I've found it a little too flexi so tend to glue an extra piece on the back side just near the mould/fillet join. To fit curves i use a craft knife to cut through one side of the corrugation being careful not to cut the other face, then if you bend it you get cracking sound and it starts to curve, cut down the next corrugation and so on till its at the desired radius' next tape it with release tape for the face or hot glue on the rear and its that simple. Cheers Matt, I said it at the start and I will say it again if it wasn't for yourself and Paul I don't think I would have been so brave, help and encouragement by the bucket! I will no doubt be back up at EC in the near future with my usual 1000 questions. Biggest question would have been these soul destroying vac leaks BUT I've been to my laboratory (garage) and and come out smelling of roses. I decided to do a double infusion and as you can see from the different colour of the bag, the left one would not seal.  I was sure as with the belly pan my problem was my inability to get a complete seal at the infusion connector/pipe so I machined some 15mm popyprop bar to become a through bag connector and WHAM 100% seal first go. |

Loving the work Chris; you've put some serious work in to get this far and it really is paying off. It's been clear from the start that you were going to go in 'at the deep end' in terms of complexity and standard of finish required - generally we advise customers to start easy and work up in order to avoid being put-off when difficult things don't go right but I'm pleased to say that you totally ignored this advice and through skill, patience and hard work will get the results anyway. It's great to have another project so well documented on the forum and being really open and honest about problems that are encountered. The nature of composites, with so many different projects and different material combinations possible is that there is *always* an element of the unknown. You have to be prepared for some problems and persevere when they occur. I can't wait to see and read more  --Matt

looking good, what are you using to make the flanges with? and how easy is it to bend and conform to the bike parts?

Haha, those flanges are slowly getting bigger!
I'm open the help, tips and criticism as learning as I go along.
If I did this for a living id certainty look at the cheaper option but its a one off build.
More importantly is the fact that 90% of my work is done in my bedroom, haha, I tried the uni mould system, very nice, but nearly killed myself sleeping in mist that was given off so bought a mega sized tub of epoxy.
Cheers red I only use the bike on track so not for show..

Wow - watching in awe - those look great. I'm glad you're not being hard on yourself regarding a few minor things and the approach of "use it" is definitely something I can appreciate. Cheers

Certainly doing a good job. One thing I would recommend which took me awhile to accept, is to make your mould flanges even wider. I don't do anything with less than a 5" flange these days, it really does make the infusion process a lot easier and reduces the likelihood of leaks. Is there a reason you are using the epoxy tooling system for the moulds? Seems an expensive exercise for such large pieces.
