need a mold for 105mm electric skateboard wheels!

Website no longer exists....

Forgive my ignorance but do the eyebolts not heat up enough to melt the pvc due to their being a larger diameter than the wire ? Do they get hot at all or is the heat concentrated only to the wire?

does the hot metal not melt the PVC at the point where the wire is held by the nut and bolt?

Have you looked into urethane additives to slow down weatherization of wheels? UV, moisture?

Great vid! I am now subscribed! i know I'm a bit late but could you potentially heat the wax cast to sorta polish the layer lines?

I know this is pretty dated, but one thing you could do is to take up a bunch of the unused airspace with something. The vacuum can evacuate much faster. (I've been using old cans of food. Sometimes their tops pull up, but so far none have opened.) I actually made a vacuum chamber basically exactly like this -- same type of chamber except the bottom vessel was stainless (top still transparent plastic), and I put a fitting on it to go to my full vacuum pump. Unfortunately, the seal shape on mine was not proper for this and the strength of the full vacuum would pull it in, breaking the air seal. Anyway. :)

did it stand up to fork hits ? what filament did you use ?

What about all natural, like gettikg color from plants and flowers etc. ?

I used urethane resin bowling ball plug to fill in some holes and I tried the acrylic paint food coloring and both tried in size over flowing the holes had to drill out idk why it worked on yours maybe the pressure pot? The bowling ball plug colors are expensive as is the ball plug. I wonder if I should order the stuff you are using and test it out on an old bowling ball

i like your approach and humility, mixed with intelligence and precision

no files

hurr hurr ramming tool

Sir, can you do a degassed water mixing with tallow or oil with this vacuum?

Capstan

Would there be a reason you couldn’t make a mold and cast then in epoxy or polyurethane resin?

Thanks so much for sharing this! Planning to make a pair of slide gloves this weekend now!

Interesting vid mate. I thought you use the vacuum for the silicone mold and pressure for the resin, cheers Graham

You should be able to degass the 2 parts before mixing. I don't know anything about resin casting, bit just based on the physics, which are that this is not gas produced by the hardening reaction but gas already dissolved in the resin.

Just use a router table?

Water makes urethane foam. The water in the screen printing ink was probably the culprit

you have to BAKE IT! 190-240C over 40minute to make it.. WORK

Hey man can you use the foam from the roar rock it make your own mold kit to sparse press?

so basically you just short the + and the - with a wire?

What’s the size of the hardware for the mold. I can’t find it anywhere on the website

How long is your rope tow?

Where to get the foam??

Im thinking of custom plywood do to the nature of my art supplies not really be suitable for the traditional long board or skateboard surface.

Those are NOT Vice Grips, those are channel lock pliers. WEAR SAFETY GLASSES when using any replaceable blade knife in that fashion. When they snap small bits of blade shrapnel fly everywhere.

But also, tjhey have wax filaments for 3d printers lol u can just print the wax. of course this looks cheaper lol but still if u wanna do super good acurate shit cheap too u can just get cheap $100 resin printer and get wax resin and make actual pro grade jewlery, of course u know that but ya i wonder, where can we get lots of cheap wax for practicing this? i was thinking about all the wax i get whenever i freakin buy certain brands of HEESE wheels!!! i KNEW I wouldl ned it one day :D its red tho,m think thatl be an issue?

To be honest, for the holes.. if you have a 3D printer, just print a support, cast a Pilothole, and drill the Kingpinhole in the hanger and the baseplate afterwards. I do have a CNC mill, that will greatly assist me in doing that kind of work.. I also like the 8 hole baseplate for wheelbase adjustment.. i've never seen that.. and i think it's cool! Since you can make these Jigs for making the mould with a 3D printer, Go Crazy, and design your own trucks, with a shape that everyone will recognize!.I have made a 3D Design (available on GrabCad) of the Bennet Vector trucks, copy the geometry, and design a less cubic shape.. :)

I’m modifying this process for roller skate wheels! This guy rules!

Comigo aconteceu isso, o uretano foi corrompido.....triste

Did you have to dampen the surface of the veneers before applying? The directions on my polyurethane gorilla glue states the surface should be dampened to activate the glue. Is this the case? Cheers, j

Why don't you just use a hot wire cutter?

Those are called “channel locks” not “vice grips”

Thanks for the video man. Excellent result. Tell me, what kind of sand do you use? I made a mixture of sand, clay and water with sugar, but I can’t achieve such a good surface as yours, I’m still experimenting with humidity, but the surface of the mold keeps crumbling, even when I gently blow air from a hand air blower.

Thank you so much for making these videos man

Will this cut very firm seat cushion foam for furniture. I have 6" thick and want to reduce to 4" thick. They are 6x22x21and I want them to be 4x22x21

I'm looking to horizontally cut a 10" thick 6' x 7', latex mattress in half (fillet style), due to the outer surfaces developing body impressions I hate sleeping in. Then I can put the outer faces into the middle and spray adhesive glue to join them. The trick is, not to cut the pieces with waves, but perfectly flat for a level sleeping surface. Why do this? California King size Natural latex foam mattresses cost $3,000 USD! So, if I can just "resurface" this mattress this way, eliminating body impression sides, I can get another 10 comfortable sleeping years out of this mattress - for the cost of making a cutter about 7' wide, and keep the overall original width too. So, I'm thinking of using wood to make one of these, a 7' long piece of wood (2" x 4" x 7')(and attaching a wider flat thin piece ofmterial to the 4" side, to it for guiding (i.e.: 1/4" x 24", x 7'), which can make the cutter lay flat and even, keeping the cutting line flat and making a 5" deep straight and flat "Fillet" cut from start to end, as I advance it over the top of the mattress (lying on a flat surface) - kind of like a planer works on wood - except in this case the planer is the moving machinery, and work-piece (Latex mattress) is stationary. Thus, I'll use springs to make the nichrome 80 wire taught, that way; why I need an extra 1' wider than the mattress width, room for the springs beyond the width of the mattress. I already have tools, hardware, and power supplies (might need 8 minimal to 10 or > Amps for a cutting wire so long). If sure AMAZON has the nichrome 80 wire, eh! Maybe I should make a video,eh?

Super cool!

Your old video didn't have a backing board. Just the clamps on the backings of the mold. Any reason you used a backing board this time for the press? I am asking why this video you did: spar -> backing board - > mold backing - > veneer -> mold backing -> spar instead of spar -> mold backing -> veneer -> mold backing -> spar Do you need the backing board or does it just make pressing easier?

A pressure pot doesn't remove bubbles, only makes them small enough that you cannot see them. Degassing the mix prior to pouring would remove the bubbles.

Excellent video. I’m done with the metal. I’m making a wood frame!

so glad i found this channel, such a diverse range of videos and experiences you've shared. This is such a rad little backyard park, loved seeing your friends get wild with it :)

What vac press do you use? Love your vid its really informative thank you. Im planning on making a skateboard iv wanted since i was little (langas board from sk8 the infinity) im so excited to do this

What pressure do you want the pot at?

Whats the suze of bolts you use for the clamp?

Any news on these? O.o

I resin my wood stuff to seal in color. I accidentally use some cheap-o markers that I had laying around, and started running when I applied a spray can gloss. So now i make sure that any markers I use, don't run, with spray can gloss. Then I can pour resin.
