That sounds like an application for a rotary broach. I'm not fully convinced it would work on styrene or if any off the shelf tools would be the right size, but might be worth checking out: https://www.polygonsolutions.com/how-rotary-broaching-works/ Not sure you could control this process to be pr...

Needs tons of info to really assist you. Feel free to message me, I'd be glad to help if I can.

Hi Scott I absolutely LOVE Badger Stynylrez Primers! I've pretty much given up on rattlecan primers on everything now. Just have a google for reviews! Airbrushable, and comes in quite a range of colours now. Ant Hey Ant! Thanks for the info. I had asked about the primer in another thread for a cust...

Hello all, I am looking for a water based primer. I have a large, 2ft., model I have to cover. Lacquer or enamel rattle can primer could melt some of the fine details. I would like to airbrush on the primer, since the primer will also be the finish. I will be spraying mostly styrene but also metal p...

Thanks very much, never would have thought of Amazon for these items!!

Hello All, I am looking for a good source for PETG, clear plastic. I need to do some vac forming and it needs to be thin, .015, .010. I have looked around and I can only find sources that 'also' carry the stuff. I'm looking for a good online plastics supplier. Any help greatly appreciated, thanks in...

Thanx much, that is a big help!

Hi All, Has anyone here worked with this primer? The label states that it is a water based acrylic polyurethane. !?:shock: Also from the label; -Simple & easy application -Self leveling detail enhancing coverage -Excellent adhesion and durability -Dries to a hard flat finish -for use on plastics...

Wasn't there a discussion on MEK a while back and how nasty it is!? Good advice suggested already. There is also an automotive product called 'flex-ilizer'. It is made for bumper covers and all of the softer plastic parts that are supposed to flex in a collision. It is an additive for standard autom...

What I usually do is apply a good etch primer, automotive. Very light coats, you don''t want the primer to melt the plastic.

I would do the usual perp-work, strip the labels with coleman fuel, clean with soap & water & paper towel. Apply your primer next.

Images pls!

What you have in the linked images looks good actually, IMHO.

I do see some seem lines that should have been filled, and maybe more bare metal exposed at the initial blast point.

I think the finished model looks really nice.

An excellent generic universal adhesive remover is Coleman fuel. No adhesive has ever resisted it, and does not attack most paints & finishes. I have use it on the paper labels with adhesive backing. Let the stuff soak a bit and gently work the surface and you will have success. With most chemic...

You can use solvent with .005 styrene, I do it all of the time. You have to use an industrial solvent, such as Resin-bond. R.B. evaporates almost instantly, therefore, small amounts on a fine brush will not melt the thin stuff. The trick is, to have the styrene strip in place, then make a couple of ...

What you could try; Press the domes in clay. Wall up around the area, pour in resin. You should then have a solid block with the raised domes on it. Take a safety razor blade, the kind you use for scarping paint, and carefully cut each dome off. Start at the outer rows and work in. You have to hold ...

Getting there...

I have had to do this very thing for pattern work, so no, not crazy, crazy inventive!! I was given a TOS saucer in cast urethane to create a non-cannon design in 1:1000 scale. Small! The saucer was all smooth, no details. After scribing the defector lines, I had to indicate all of the windows, circu...

Good trick! ( I've been doing the S.glue trick on stacked plastics for ever)

Links are all denied to me as well.

Thanks much!

I have not received a Micro mark cat in long time.

Hi All, Looking fo a good supplier of CA accelerator or Zip Kicker. My local HS closed last year. :x I would get the large bottle and refill my atomizer. I have since purchased a small bottle at an HS further away. I use a lot of CA throughout the year so I need a lot of accelerator. It needs to be ...

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.

Good luck.

Scott

Great minds.............^^^^

You might also consider investing in some styrene shapes, like form Plastruct or Evergreen Plastics. I have just about every shape they produce, half round, quarter round and even triangular shapes, 'i' beem, L beem, etc. When I mastered the TOS Galactica for Timeslip, I used only 5% kit parts for t...

I had forgotten about the 'Book of Aves' ! Very funny!

Yep, use all of those guides shown for scribing.

Ditto much of what has been said already. I actually covered this in the class I taught for Sci-Fi-U on Friday @W.F. this year. The dull Xacto blade is the way I scribe and that is what I discussed. I follow that with a fine point steel tool. Just a finely ground point, nothing fancy. Sand down the ...

I will ditto everything posted so far accept for using a hollow ball in the joint, you will crush it.

You can also use BIONICAL parts. I used them to breadboard a concept of a robot for a client, worked great. All of the products suggested will work fine. Good luck.

Thanks for posting the MSDS, Kylwell. I took a look at REZ-N-Bond, since I have several quarts on hand, and found it had MC in it, which I was unaware. :shock: I knew it did not have MEK in it. The only difference with R-N-B, is that it welds ABS together and styrene to ABS. I don't know if Tenax or...

Yea, IMO AbsoluteSciFi, return it and purchase some Rez-N-Bond or similar solvent.

Scott

Its exactly the same as Ren board, a urethane product. There are several different densities of Ren board, just like this stuff. Not that it matters to me, use what you feel comfortable with.

Scott

Hey MilleniumFalsehood, I use Rez-N-Bond for all types of plastics. It will weld styrene and ABS. I buy it in Gallon & quart containers. If you do a Google search you should be able to find it near you, maybe even have it shipped. Nothing personal, but I wish we could do without MEK. It is just ...
