DT, Most people haven't ) It means cutting up a board. Its a good thing to do. Let's you see what's going on and what needs adjusting. The second calculator is a good one - it will give you are sense of expected thickness of the laminate. Dry would be at the very extreme end of the issue. http://www...

DT, Skimann mentioned that his top mold could be a little tighter, so the first step is to iron that out. A few things might help, Have you tried put a blank snowboard core in the press and running a normal heat cycle? Does it come out flat? This is a good way to understand the potential effects of ...

Try a set of racket straps in lieu of actuators. Add a couple of spacer between the top and bottom mold so that it isn't damaged during the trial. The thickness of the tipspacer. This is what co-surfer used for a while. Edit: Pinch points can be created during inflation of the bladder. Usually the b...

Pressure, or lack of pressure around the tips can cause an issue with raised edges. Adjust you press design to include linear activators ... or a set of four bicycle pumps, whatever suits your budget. Otherwise, you are fighting against the edge set .. leading to internal tensions raising the edge s...

Whether you wet out the core. It depends. If you are using bamboo as a core material, you can do either because it makes no difference, as the epoxy does not penetrate the material i.e. surface preparation is the most important factor. If you are using hardwood/softwood core, then you need to hold i...

Epoxy, it will fill any gaps. A negative mdf template and a guided router bit will help you improve the finish the next time you do this. A layer of fibreglass between the two parts would increase the pull out resistance. Sharpen the drill bit before drilling the holes for the binding screws, this w...

Great insight Eric.
You are right, using ambient cure epoxy will simplify the process. Leaving only the calibration of pressure to obtain the desired laminate thickness using an online tool like this: http://www.saertex.com/materialrechner/ ... echner.php

As you appreciate, the issue is 'work', impacting the fatigue resistence of the wood (or not), so the relationship is a little more complex. Broadbrush ... Light weight, open pore soft wood ... then you are turning the core into a composite, a wood epoxy composite. This means more epoxy, ideally a l...

Well done with the bearings! I'm not sure you are going to get the AL angle to provide the results you require ... you may find that they twist when pushed up from below, especially as you will be pressing down from above. You can make accurate rails using a strip of wood screwed to mdf. Pass the md...

The stuff about the design and layout of the pores of different wood species is good and seems to really be a factor in choosing different wood for what you want from a core. As a general rule, the more dense the wood, the less sensitively you will need to treat the issuses of resin ratio, resin vi...
