Without knowing your design and target weights I can't make a recommendation on what material to use. There are a lot of variables that affect the weight of each material; number of layers, resins used, etc. In terms of strength to weight carbon fiber is probably going to be your best bet, but that ...

There are different styles of fiberglass, the spray on chopped stuff like you see on bathtubs, or the sheet layup seen on aircraft, you can even get honeycomb fiberglass panels that are light and stiff. One of the new advances in fiberglass is what they call 'pultruded' shapes, the glass fibers run ...

Have you considered Kevlar composites or even fiberglass? No sense in going the Ferrari route cost-wise when a Buick will work. Another thing to consider is that if you make the legs and body out of a very rigid material this could negatively impact the joints as well, ex. any bending motions that w...

Future cures fairly hard after about 24 hours (more or less depending on local conditions) at this point I've never know it to flake or rub off, if you have to remove it at this stage either household ammonia or rubbing alcohol will remove it. Sanding out the masters to 2500 and then polishing them ...

I've never heard of a way to fix cracks in styrene parts like you mention, I have heard of people applying Future to the cracked area and letting capillary action suck it into the crack, the crack won't totally disappear but short of a very close inspection it will be invisible. How long would you g...

I've seen that before. I suspect that what happens is that the final coat of clear lacquer doesn't adequately protect the shiny aluminum layer, which gets oxidized into (transparent) aluminum oxide. I agree, there was a GIJOE toy from the 80's that suffered from this problem as well: http://www.yoj...

Painting deep recesses with a spraycan
Got a bit of a puzzler for the group: I'm building one of the Hawk 1/4 scale car engines as a Christmas gift for someone, the plan was to mainly do seam cleanups, better painting, etc, I didn't want to go all out and superdetail the model, one of the changes I decided to make was to strip the diecas...

Plastruc cement will work on ABS or PVC but I'm not sure if anything holds POM. Of course there are usefull metal parts also. POM seems to be similar to PTFE (Teflon) and has similar bonding problems. I love the metal parts in things like this, printers are a good source of high quality cold rolled...

Hey apsilon, I have been told, but never investigated for myself, that you can have extruded aluminum created to your specs. Its worht a shop. Minimum order quantities and tooling charges will kill you unless you order thousands of feet. I checked around to see what it would cost and one place offe...

I know that Plastruct makes a lot of rectangular tubing but with sharp corners, I've also seen thin wall rectangular brass tubing but it has sharp corners as well. I take it you're looking for something that looks like structural steel tubing? Best idea I have is to sand off the corners of the Plast...

Not sure, I asked a similar question to one of the clerks at the local store about a week ago. For a good while the store was out of both the gloss and flat versions of their white and black paint, I like their flat white as an undercoat for a lot of colors. He said that the supply on the store bran...

Correct, I haven't seen the old plain "Future" label since the switchover, I think all of the old stock was removed and sent back.Dr. Snuts, M.D. wrote:Just to be certain, is this the stuff I'm looking for?

as to air bubbles in the resin, if they are in there, they are small enough to escape my eye, and even if they where than small, the pressurizing of the tank would crush them I'm thinking of bubbles more along the lines of what you see in a meringue (for example), its technically a foam but you can...

Ok, with the mold design and resin staying the same as before then what other variables or changes are there since last time? Have you changed the way you mix the resin? I still think that there are voids in the mold or air bubbles in the resin that are collapsing under pressure, causing the void sp...

It looks like to me that the mold is full of resin prior to it being placed under pressure, as the air bubbles collapse the resin volume decreases and slowly drops, there doesn't appear to be enough resin in the reservoirs to fill this space before the resin starts to set. The reason I'm thinking it...
