Hi,

Any advice on how to make a nice looking snorkel (straight tube) out of CF its 4.5" (114mm) outside diameter and 4" / 100mm long.

I tried wet lay-up round a sacrifical former with vac bag film over the top taping round it to provide some tension.
The layers consolidated fine, result is ok but not super smooth (although I haven't gelcoated it yet).

I could make a mould at 117mm id but I expect it would be hard to neatly place 3 layers of CF and then a pain to vac bag.
I could retry the former route and seal it to pull a vacuum (former would need to be fairly strong I guess which would add to the release challenge).

Is it feasible to get a good finish with wet layup and vac bag film pulled tight round the part?
Its not really on show so maybe I'm being over fussy.

Any views appreciated!

Thanks
Stuart
