Re: Drying Kit

Cut a hole about 100mm x 200mm as low as posible and same as high as posible and as far away as posible from first hole. Fit louvre grilles to stop animal ingress. Temperature differential between hi & low will do the work. This is the basis of all non powered ventilation and works well. Drill a few...

Re: Carbon helmet layers

drking. Thats right, you will not need UV proof clear laquer if you are colour painting the lid. You only need the laquer if you want to see the carbo/kev weave as a style feature. Also ,do not discount biaxial or triaxial glass cloth, bit more shock absorbtion than carbon and cheaper, not a huge we...

I dont think you can class the posible impacts as "relatively massive" Were taliking 5mph on a good day. Just spreading that load over as large an area of cranium is probably going to be enough with a little foam also. But agreed , its mostly hype and bling factor and a padded yellow builders helmet...

Re: Carbon helmet layers

Rinseout. Im not familiar with that make but if as you say it is allready painted then it should be ok. 2 pack paints are always top of the heap. Check with the manufacturer first, some paints will deteriorate some plastics over time

Re: Carbon helmet layers

Pigmented resin will only give a satisfactory finish in a high viscosity format ie gel coat, applied in a thick layer. Not really what you want for your job. Your far better painting it after cure, with the bonus of custom artwork being a reality

Re: Carbon helmet layers

Gell coats are not normally used in high performance composites as they do not contribute to strength and add weight. Instead, the item is given a finish after its been made (2 pack paint or clear laquer) applied by spray gun. Gell coats are a throw back from the days of polyester resin and chopped ...

Re: Carbon helmet layers

You can leave it in mould as long as you want. Higher temp will speed cure. Bye the way, if youve never used epoxy, extreme accuracy is needed to measure the resin and hardener. Use syringes for small batches or a 0.5 gram accuracy digital kitchen scale for larger batch. Some people seem to think yo...

Re: Carbon helmet layers

Composite reinforcement materials go by grams/sq mtr not thickness . At a guess 3 layers of about 400 gr carbon biaxial cloth would produce a strong item if well worked with good epoxy. You can at extra patch reinforcement at critical areas ie strap bases. A vaccum will almost double the strength/ w...

Yes, leaf springs are far superior to those indespension units, sureley you dont think they have dampers ?
The trailer will be fine. Look at the load specs. If it measures up to the weight of boats you envisage carrying then youre game on.

No theyre not,they may be electro plated with a couple of microns of zinc, certainly not hot dipped galvanised like a boat trailer would be . And it doesnt matter what section a steel bar is, a thin walled box or a thicker angle ,both can be specd to take the load. It is wrong to state that a box is...

Re: Canoe trailer help

I disagree. Your car is not galvanised and car panels are 8 times thinner than that angle. Only needs galvanising if your dipping it in the sea all the time. Also angle is as strong as any section, it will have been calculated on a size/load basis. Take a look at the Eifel tower or a bridge. The tra...

Re: Carrying a playboat on a rear mounted bike rack!!!

It would be within the weight limit ,but the windage of a yak in that orientation will try to rip the rack off more than 4 bikes would. Go slow and it'd prob be ok but if it rips off and kills a motorcyclist youll be doin time.

Do a Ray Mears and pitch up in the woods at Newbridge . Or, campsites worldwide can be found via google, some will be shut for winter though.
