quang Posted April 13, 2021 Share Posted April 13, 2021 To me, the main purpose of a jig is to allow the modeller to adjust the geometry of an aeroplane constituents: dihedral, angle of incidence, raking angles of the UC, etc. A real jig would at the very least allow you to check the symmetry of a build. Another interesting feature of the JH jigs (and the likes) is that you can safely and securely affix the model to the jig by a simple system of rubber bands. The model cannot be knocked off nor its paint damaged as it cannot move while on the jig. I find the JH jig especially handy when I have to move my in-progress build around without even having to touch my model. How safer can that be?

ivanmoe Posted April 14, 2021 Share Posted April 14, 2021 So, I bought one of these things and it arrived today: A question for you gentlemen who have used one in the past... Would it be a good idea to clear coat the sub-assemblies before use? I ask because I'm thinking that the moveable parts would slide/adjust more easily if they had a gloss coat on them.

mozart Posted April 14, 2021 Share Posted April 14, 2021 I have the Vertigo jig and absolutely love it. My JH jigs have just about fallen to pieces.....too fragile. Would be happy to take the biplane one off your hands Quang! Link to comment Share on other sites More sharing options...
petrov27 Posted April 14, 2021 Share Posted April 14, 2021 Vertigo purchaser here - works well enough, I also purchased it with the idea it would assist with lining up extra (biplane) wings and such vs. just holding the kit but I do really like that padded box solution a bunch.

That's what I was really getting at with my question about the clear coat, even if it's just Liquid Pledge brushed on. I'm thinking that it might make the wood more resilient and robust.

Never been happy with them. Firewood!! Edited April 14, 2021 by mozart ivanmoe and Out2gtcha 1 1 Link to comment Share on other sites More sharing options...

Out2gtcha Posted April 14, 2021 Share Posted April 14, 2021 I currently have two JH stands, a 1/48th/1/32nd stand that I use for my Tigercat and another larger 1/32nd/124th stand I use for larger models. Ive had my Tigercat strapped down to my 48th JH stand for years and years, and has stood up to it all.....painting moving adjusting and having it as a rest point for the F7F. The issue is that you need to soak the entire pillar sandwich with thin CA. Once that is done, the grains of the wood get tough, and you no longer have as much wiggle in them, and they dont tend to shift or break. mozart and ivanmoe 2 Link to comment Share on other sites More sharing options...

But does it tell you that in the instructions Brian, if not (and I’m sure it doesn’t) how are we to know? I used wood glue, since it’s.....um......wood!

Out2gtcha Posted April 15, 2021 Share Posted April 15, 2021 I guess I've just not got a great confidence in wood glue to hold things solidly on super small parts. My dad got me into peanut and walnut scale FF models when I was a kid and they always had to be super light, and the one thing that always made them strong and light was bonding layers of the light balsa together with thin CA. I guess it comes from the plastic modeler in me wanting to use CA instead of slow drying wood glue. After fortification with CA my JH stand have survived many many years of me torturing it with everything from spraying it down in the paint booth to dropping it fully with my Do-335 attached. I even soak the single layer upper stand pieces themselves in thin CA and it really strengthens them up to par. Honestly I dont think I even read the instructions of either stand to know if the CA trick was in there or not..............I just knew it always worked prior for compact or small layers of wood, and the assembly process for the stand was pretty simple and straight forward. ivanmoe 1 Link to comment Share on other sites More sharing options...

In your initial post you mentioned ‘fancy stands... wooden ones and plexiglass ones’. Those are known as jigs. If I‘ve known you were asking for ‘something to hold the model while you work on it’, I would have suggested a pair of cotton gloves. Link to comment Share on other sites More sharing options...

Wrong, a jig is more of a fixture to hold a workpiece firmly in place while tools work on it, like you see in factories. Jigs for building models are used to hold components in precise alignment - like biplanes, but they are more commonly used in the construction of flying models. But what do I know, I was only a tool maker for 7 years. Out2gtcha 1 Link to comment Share on other sites More sharing options...

I'd have to respectfully disagree with that. Where I am from a stand is just that; something to stand the model on while you ar working on it....hence why "stand" is by far and wide the most used term when describing the JH models stand. When I hear "jig" that says something that has the ability to lock the model down and manipulate it while still strapped to or attached in some way. A jig also can be something that one can use to build to keep something still while forming or otherwise making something around it, keeping everything in place; IE like a welders jig. The JH biplane stand is IMO closer to a jig, as it's used to line things up on the model, but still to me is just a stand, as you are still not able to maneuver or otherwise manipulate the model. While you can put bands over the model on a JH stand, you have no ability to turn, move, twist, flip or otherwise manipulate the model while on the stand, and unlike a jig the JH model stands have zero ways of precisely holding the model in the same repeatable and measurable way. It's also worth noting that both terms are used to describe the stand on the site selling it, so this more boils down to opinion that any kind of concrete facts.
