Hi All,

Another question for all you experts. As stated before I build primarily armor and I set my vehicles onto ground work. Recently it appears majority of my bases are warping on me. For groundwork I use Styrofoam and celleclay. Usually I pick up wooden bases from Michaels or Walmart. Is there something else better for armor and aircraft as in bases? It sucks when you have a great build, nice groundwork, but your base has warped.

Thanks
Ken

Ken,
I just tried one base for my Mig and decided not to use it. It warped. the wood was too thin [1/4" plywood] and the glue I used to attach foam core to the base warped the wood.I did  not weight the wood and foam core down as the glue was drying. the glue pulled the warp into the wood. I used to build furniture and should have known!!

I notice that a lot of builders use a thick wood base that cannot be warped.

I don't know how you could put a weight on a curved, sloped, irregular surface top though? maybe use thick wood [glue several layers of thinner wood together to make a thicker base and weight it down till it dries completely?] base and glue a FLAT piece of styrofoam to it--weight it down till dry, then build up the styro in layers for raised areas??

I found some of the craft store wood was light pine or birch, which sometimes is worse to warp as it dries out on its own. Some home stores like Lowes and Home Depot give away woods scraps and also keep smaller pieces of wood in the "finish" wood section. It does get expensive to have to buy a long piece of lumbar and then you have to have a saw to cut it with. other problem is that a lot of construction wood is already warped in one direction or more. its a headache to get exactly what you want without blowing the budget!!

What thickness board and what material did you use Ken ? The base I have just made has warped a little but it was only 1/4" hardboard, and I think the moisture from the glue affected it ! when I make another I am going to use MDF and put a profile around the edge with a router. My thinking being that MDF is pretty stable as opposed to natural timber that expands and contracts

Hi Pete and Ted

Pete I am using 3/4 inch thick base that I bought at Michael's. It is light wood, so I think that could be the problem. Ted is probably right, I need to go to like Home Depot and see how much some thicker and heavier wood would be. I tried water proofing the wood before I start my groundwork but majority of the time that does not work. A co-worker wanted me to build him a Chinook, another first for me, and put it in a little diorama with figures and such. I used a 18"x14" picture frame and premixed grout as the tarmac and in my opinion it came out decent. I decided to post a pic here to show you how it looked. Please forgive the inaccuracy, The Chinook is a CH-46E Bullfrog, Marine version. He wanted me to paint it Army colors and throw on some Army decals on it. He is paying for it, so I need to keep the customer happy. I am going to see what kind of wood I can find tomorrow, if I find something good I'll post it here.

Ted I looked at your post about the runway for the mig. It looked real good. I might buy me some of that foam core board just to have it on hand.

Thanks again
Ken

Hi Gra

I will look into the MDF and 18g plywood and look at some prices. I appreciate the information.

Thanks

You could also consider 6mm or laminate glass and eliminate warping completely [smile]

Hi Pete I use ceramic tiles either the 5x5 inch for say 1/72 builds and the larger floor ceramic tiles for 48ths and 32nd's most diy centres will sell individual tiles from there damaged box stocks I bought 25 various sizes from our local B&Q d.i.y store for £4.
I use contact spray adhesive or photo mount spray to fix on 1200 grit wet & dry paper that serves as a tarmac then just airbrush various greys and browns to get the desired effect.
I have also used cheap picture frames as well and used the glass as the base.

My solution to fix the issue for the warped irregular shaped terrain bases...

Goto the local playground and 'borrow' some sand.  Put it in a plastic trash bag.  Glue your base.  Gently put the bag of sand down on top of it filling the nooks and crannies of the terrain and attempt to level the top of it as best as possible.  Now add the weight to prevent the warping.  You may need to brace the sides with books or something to keep the bag of sand from going beyond the base.  The sand should conform to the curvature of your base and provide support to allow even pressure when weighting it down and not crush your terrain.

DISCLAIMER: I have not tested this so it is just a suggestion, but in theory, it should work.
