Uni-Mould vs EL160 High Temp

Robert72 - 6 Years Ago

They are completely different resin chemistry. The Uni-mould system is based on vinylester and polyester and is suitable up to 90C. The EL160/EG160 high temperature epoxy system is epoxy based using ...

EL160 renders Uni-mold redundant? Can't see the point in paying more for a less versatile system. Unless there is a benefit of Uni-Mold I am missing.

You must have got something wrong here. I guess you are talking about the moulding paste. You will need at least the high temp gelcoat in addition. This will be least 110£ for the smallest batch, wic...

Epoxy is also harder to work with. Systems like the Unimould are extremely forgiving and easy to use, epoxy systems are significantly less forgiving and often hard to repair if you do make a mistake.

Yes, you are right, Uni-Mould is cheaper, apologies. I made a mistake with my numbers. Still, a female for my telescope tube project is running to £600 (plug and female). And that is before I even...

What for an telescope are you building? Something mounted in a medium sized building? With the big starter kit you could definitely build quite a huge telescope mould. Usual mirror telescopes should....

The tube is 1.5m x 0.3m, unfortunately just a bit too big for a small kit per side. I have worked out that to finish the plug (sonotube), the parts come to £227.64, this includes a laminate skin,...

The area per side is 0.8 sqm. Do you think I could stretch the 0.7 sqm in the small size kit to this size? It may be worth considering.

Is it a simple tube? If so, I would get a 300mm brown kg type tube (kanal grundrohr in german) and take a would from it, using a melamine coated board as temporary flanges. And then just sand the...

Thank you again for your reply. Yes it is a card tube: The diameter is 295mm. My intention is to build it up to 300mm with woven glass (for various reasons). then prime it with pattern coat prime...

In my opinion this is far to complicated and unnecessary expensive. And will likely result in an uneven surface. It is quite difficult to sand a tube perfectly round without a jig. I would take a kg....

Sorry oekmont I am completely baffled.

Robert72 - 6 Years Ago

You want to take a negative mould from a 295mm cardboard tube, wich you want to cover with glass fibre until it's 300mm diameter, right? To finally make a carbon tube, right. I would not use an...

I would indeed have used a plastic tube for cheap money if I could get one where I live. Unfortunately all I can get hold of is a 3m length of Sonotube, however it is incredibly straight and round. I...

You can even get 300mm tubing at amazon. In Germany you have to search for "kg rohr dn300". Every good hardware store should get their hands on that dimension. This is used in every bigger building.....
