Hi there. To have an angle that has the most resistance possible to twisting, (like one hand on each side of the part and twisting your wrists), we should have the fibers orientated in the 90/0 degrees, right? Thanks! :)
Preventing twisting is difficult as the stresses are in all directions. Using a bidirectional weave is, in my opinion, your best bet. Some people recommend that layers should be orientated at 45 deg to each other but, according to my carbon supplier, this will make very little difference and can result in increased material wastage.
It randomises the hold feature, you will see recesses in the yellow cams the gap can be adjusted to make the holds more or less frequent. my machine also has a switch to allow it to hold after a hold or win i couldn't see one in the vid
Yes, about time :-) However, we have a couple of issues. One being the ECU, although top of the pile when purchased, doesn't support drive by wire. When we got it DBW wasn't 100% reliable so we stayed with cable. Since then we have updated to DBW. So a new ECU is required and has been ordered. The other issue has been trying to install the software on the PDM. Hopefully, we will be able to sort this out tomorrow with a Teamviewer session with the Danish manufacturers of the unit.
Thanks. Adjusting friction would be difficult, but I can adjust the clearance between lever and release cam with a file. However, the handle and shaft are so light that I hope this won't be an issue. pudding, proof, eat etc :-)
Dont count rich. Plastic (PC, PMMA) screens scratch easily due fine street dust and are hence not allowed by EU law for street use, hence not street legal. Allowed for concours and racing: OK.
For windshields that's true. For side windows more is possible. But here in NL the cars older then 50 years are exempt from the yearly mot technical check. So unless you make an accident where the windshield was the problem, nobody will ever care.
I know a small company in Serbia which made a new windshield for our truck , wasnt expensive . Ive just checked they are still in business. With cars I would rather go with that option . Anyway , you did a great job!
Only problem using poly for windscreen is that it scratches extremely easy. first time you use wipers in the rain it will scratch so badly you cannot see clearly through it.
OMG - this is incredible! I have fantasized about building a modern day Broadspeed Elan, but his is so much more. I’m confused though by the gearbox setup… is that some kind of SMG type arrangement?
Is this for a UK road legal vehicle? I see very conflicting info about this topic, ie if you can or cannot (i'm hoping i can). It meets the main criteria i'd say of not shattering in accident, but the MOT does say glass with no other mention of alternative. Just need the right MOT tester who agrees?
My MOT tester said that as long as the wipers work then there is no problem with poly. MUCH safer than glass and around 250 times as strong with regard to shatter resistance.
nice little piece of tool you got yourself here Steve, hopefully playing with it won't take you too much out of the fastest elan on the planet, still looking forward to see that one on the tarmac...
Hi. Yes, it is a nice piece of kit, even better now that it is square :-) I have finally started back on the car after a 2 year hiatus, but the last 10% takes 90% of the time :-)
I'm researching my options to make a new windshield for a 1968 Mark Twain 14 foot fiberglass runabout. It looks to me from what I have seen is the best approach is to create the form you want your acrylic/polycarbonate to assume, position it, gradually heat your oven, hold the temperature high enough for the plastic to fully drape over the form, then SLOWLY let the oven cool. I see so many cases where people are pulling their plastic sheet out of the oven into the cooler surrounding air and immediately the edges of the plastic begin to cool and deform the sheet, making it difficult to work with. This did not appear to happen here at all. Well done and thank you for the education!
Yes, it is very important to dry out both the poly and mould before the poly reaches its sagging temperature otherwise there is a risk of bubbles forming.
A home made unit (1.8m x 1.8m x 0.9m) and a digital controller so the temperature can be ramped up at whatever degrees/minute are required for the resin being used in the prepreg carbon. The controller also allows for any temp to be maintained for any length of time. The heat is provided by an old domestic oven element and fan.
Hi Steve, I have a Treyrx 1000 SXS and I’m going to put on my own polycarbonate windshield and roof. My question for you, would you put a short video on forming the windshield using a green dye or maybe Acrylic paint ? I was wondering if the water blemishes could be use to put color where you want. Thanks,Brian
