any word on the new material? the great unwashed are waiting. 


They are about ready to give it a proper title and offer it up for sale. I am just about to get 65 meters of the stuff and this is the most I have had in one go, as they were still fine tuning the formulation I guess and are now confident that this is as close to production ready as it ever will be.. They are also testing another material at the moment with better clarity which I also tested and it shows promise but does need a little more time on that one and this one is so new I only got 0.3 of a meter of the stuff to test!

Sorry it seems to be taking a while to be launched but I guess they are making sure it all works and have been doing some out life testing after one customer had a problem when it was shipped although I do think that was more a shipping problem with delays and hot warehouses than a material issue.

Trust me guys it is worth the wait and seems to make VTF261/ Easypreg  look out dated.

No new news.. I know another guy who has tried it and had some problems.. Not sure why. I am getting a test sample from him and so is the manufacturer so for now I dont want to say who make it until I am happy as well as them being happy with the material. I really have had zero issues and I am happy with the material, the other guy has had problems which could be curing process or material or anything in between....


I made this, this week and it is great...


This too.... Please ignore the line down the centre as the mould split is offset so have the mounting on one half of the mould so it would never have an even V down the center so as they will be painting it I just ran the strip down the center so they can give an illusion of the V.

Still a development item apparently... I have had about 15 meters of the stuff so far and it is flawless... But there have been a few small changes to make it better and make it a little more forgiving when you cure it..... I think it is a little less critical so it is a little more suited to amature use too...

Hi Tha Pop..
Sadly I have never done infusion. I have done wet lay in a vacuum bag and pre-preg. For me pre-preg is the most consistent and cost effective as rarely have any parts that could be seen as genuine scrap parts. Material costs are higher but not so high it makes the parts very expensive to make.. Also I dont need mesh or tubes or MTI hose and there is no excess resin which could bring up the cost of making parts close to pre-preg and lay up time is reduced. But you do need an oven. I made mine from MDF, chinese fan heater and a PID controller. It works perfectly and cost about £150 to build and is 1.2 meters wide x1.2 meters deep and 1m high.

I have been asked to take over a job from a company who are making some small personal water craft. They infuse them and it takes them just over a week to make them from start to finish. In pre-preg the same job would take me 3 days.  So I could make two in the same time it takes them to make one so would in the end be more profitable and even someone making parts for personal use or as a hobby is quicker to do.  I do think understanding wet lay is quite important and if you use polyester resins cheap and fast to do. I think it has helped me and I have gone from doing it as a hobby for my own bike to now doing it as a business full time and making parts for other people. If I had to do infusion yes it would save some money but the extra time is takes to do would make up the difference and possibly mean in a week I actually make less money.

I can make a complete motorcycle fairing in 2 days where doing infusion I would think it would be almost double that. Turning moulds round is minutes and the covers I have done here I do one a day which is over a £1000 order in 5 days. Each one only takes up half a day through to putting them into the oven. If I had two mould and the customer wanted 10 per week I would do that easily... I dont think I could say the same for infusion and I would still expect some rate of scrappage due to air entrapment in the weave or some minor surface blemish ect.. As long as I follow my methodology and cure them accurately I dont seem to have an issue. I had two in this first batch with problems. One was pinholes due to the new oven set up being out and one due to spider cracks in the original mould the customer sent....
