Re: epoxy cure time

This really depends on the specific epoxy you are using. There are so many formulas out there with different requirements and curing cycles. I would suggest that you try to contact either the seller or the manufacturer to find out if it cures at lower temps.

Re: Jonrezz’s Build Log

With the tilt base router you still have a bearing on your router bit. It's basically the same bit you use in your router table setup.

Re: veneer topsheet with painted graphics

The gold standard would be epoxy based paints. Basler in Switzerland make a variety of products that can be used for this purpose. In the US Nazdar Inks makes similar products afaik. There are some other products that work too, however I would suggest you do some bonding tests with something that is...

Re: The pouring urethane sidewall thread

If you look through this whole thread and google the datasheets for the different PU resins people use, you will get an idea what hardnesses work. From what I'm aware of around 90A is on the softer side of whats regularly used and around 70D is on the harder side. VDS rubber should still be used wit...

Cheers! Glad you like it!

Nice new board...looks like it has a little "spoon" in the nose?

Re: Round Top skis 19/20

Sounds like a plan! The important thing is to fill those small gaps from the bottom up. If you don't do that the epoxy might just stay on top of the gap and not fill it due to its surface tension.

Re: Round Top skis 19/20

I would use a thin epoxy and a small syringe to fill in those gaps.

Re: Mould building material?

I am assuming that by "chipboard plywood" you mean OSB (oriented strand board), correct? If so, it depends on what type of press you want to use it in. In a vacuum press it shouldn't be a problem if you sand everything smooth. In a pneumatic press I would guess that the mould would crack under the h...

Re: Round Top skis 19/20

For tighter bends you could try making a second tile nipper with a smaller (maybe even rounded) "nose".

Re: Should I cut out the wood and glue

Kinda hard to understand what happened from your post, but I assume you drilled your insert holes in the wrong spot. If you drilled the holes in a raw core (i.e. not already pressed into a board), then I would recommend plugging the holes with wood dowels glued in with regular wood glue (preferrably...

Re: Soild Wood skis

Depends on what is "viable" to you. Others on here have successfully built skis without ptex bases. Here are some older posts with info on this:

Re: Round Top skis 19/20

I assume this means that the vacuum was not pulling enough or I did not use my j-roller aggressively enough to really flatten the skis. Did you put a breather fabric over the skis during pressing? Just asking because it's hard to tell from your pictures and this might be a reason for the lack of pr...

Fortunately not! No new snow either though haha.

The new board looks great...the wavy parts of the flax/carbon almost look like wood grain.
