@vineman: yes hotglue is the ticket, just pita to remove. you glue it full length (on the thin parts) or just drops every some cm?

@chrismp: its mr. hobel :)

H-H log

So, i think its time to show some steps and findings ... All starts with a good shaper: goes on with planner crib (thanks forum!): Did use leftover wood for spacers, planned to full mm sizes and use 0.2 & 0.3mm steel spacers to get the sizes i need Tried to avoid edge pullout via couple of methods. ...

@mikic: Tred it out, somehow i always get an error when i try to put in my 30 measure points @twizz: Thanks a lot! I understand now (in theory) how to calculate the deflection of a beam ... to generate a diagram out of it should be easy. But where i drop out ... how to project this formular on a non...

Btw. we did put a new empty ink tank and a full one on a scale, it was more then 0.5kg difference.... 0.5kg ink just wasted ... :|

Maybe you can do something similar on the T3200:

I ordered some cartridges via ebay, its a chinese seller. Shipping was quick, but i assume it hangs at customs right now. I can tell you more when i receive the cartridges. Ordered some ink dampers too (think of ink filters), these can be blocked by supply ink. Good to have spares on hand (2-3$ / co...

Cool, did see this before but forgot completely about it. As long as i can put enough vectors for the core profile (lets say every 5 to 10 cm) im totally fine. Will try it out @twizz: yes i know that solidworks is total overkill ... did look into beam equations but got stuck ... not enough basic the...

Better you get a cis system or refillable cartridges. Always cheaper to buy ink in bottles then in cartridges. Dont know with the T3200 (just have the 7600) but look into modifying the ink waste tank (an 7600 drill a hole in the waste tank, put a tube in and the tube into a bottle fixed to the print...

Thanks, i have this spreadsheet already. Youre limited (without hacking) to these params, so just trapezoid cores Tip Thickness 3 mm Mount Thickness 9,5 mm Tail Thickness 3 mm Tip Start 710 mm Mount Start 200 mm Mount End 200 mm Tail Start 710 mm Im looking into solidworks right now, but this would ...

core profile simulation

Is there an easy program to simulate bending of profiles (core profile)? Would like to experiment a little bit with different profiles /trapez/concave/convex) without cutting up too much material (other problem is my limited access to the profiler i use). I know theres stuff like mathlab and so on ....

Maybe J-Teck (J-Next ink) is more friendly ;)

2 channel controller (w. 2 sensors & relays) is a good idea ... if you have different heat sink top/bottom it ensures a nice balanced heatup (gray theory, only from my experience in other applications)

So generally speaking for a nice carving ski with good grip on ice a smaller abs is better (lets ignore the ski flex now, just edge related) but for a more forgiving / easier to repair edge a wider abs is a good idea (powder ski). The ABS breaks on high impact, but its easier to replace then a smash...

Really nice vid :)

Btw. use nitril gloves, not vinyl (or latex) for epoxy ... these are useless regarding the chemicals (except for keeping ur hands visually clean)
