Please do Hanaldo.  You always been a great help since I started infusing.  Thanks

Ha, never thought of using chipboard Nice one, I used clay for my last attempt at making a flange but found it really hard to keep it to the edge of my part as it had a long curved edge. I ended up with the flange too far up the edge of the part and had to mess about with the mould to get it near the correct dimensions, it will probably only work once before falling apart. If I try it again I will use flexible plastic on the curved bits (probably supported by clay or plasticine) and your suggestion of chipboard for the base.

Good luck with it Whitecel but you might find it easier (and a hell of a lot cheaper) to wrap the part.
This guy does it for a living and shows how he does it here.

Will have a try,easy to do but bloody hard to explain !

we use melamine faced chipboard as base boards and lots of the flanges, gives great release and and can be used for everything from GRP to pre preg

Cut a base board bigger than your item you then need to fix your item to the base. I would fix two blocks onto the board to the correct height I use p38/easysand / put masking tape on the back of your item in the area of the blocks

Sqeeze it down onto wet filler and hold till it sets and you will be surprised how firmly its held,I would have the item so its long straight edge is sitting on your base board

Work round the item doing all the remaining straight edges with blocks bracing each part to the base board

Fill in the corners with shaped wooden blocks.filler.sheet wax

Had a similar problem with a part I was working with. Didn't really get a good solution as the two moulds I took from it both had issues so very interested in the answer.

Hey guys,
