Magnetic building system


       Remove this ad - become a site supporter!
I have some kits I will be building this winter and I like the idea of putting together a magnetic building board. I know you can buy kits in the US but once you add shipping, duty and the exchange rate it gets ridiculous.

My current work table has a plastic top so it is far from flat. On top of the table I will use two glass sheets for a flat surface. When building I would put the metal sheet on top of the glass to keep it flat

The kits I will be building are in the .40-.60 size so nothing huge. This is what I am thinking of piecing together:

Most of the hardware stores sell sheet metal. My glass pieces are 24 x 36 so I will stick to that size. Canadian Tire sells a 22 gauge 24x36 coated metal sheet for $36.99. The trick will be to find one in the rack perfectly flat without damage in the corners.

I ordered 2 sets (100) of these magents for $50.91 shipped.

The downside with the magnets I ordered is if you drop one it will probably shatter.

The ceramic magnets you can buy in the US is sandwiched between two metal sheets but I cannot seem to find them in Canada.

To brace pieces at a 90 degree (like the fuselage) I can buy some of these and hold them in place with the magnets.

Or I can buy a sheet of plywood and made some fixtures like these.

Another thought is to buy some welding magnets like these.

Princess Auto will have these one sale next week at up to 70% off.

What do you think?

Re: Magnetic building system

I made my own, yes you will have to bite the dust and order from magnet source in the US $55 for 100 pieces. wood I used the 36" popular pieces from lowes/homley-depot, their straight and true, available in different widths. Just take the time to make proper jigs, and cut/drill/cut/drill/cut/drill took me the weekend to make 16 pieces, as for the metal base find a metal shop and have a piece cut, you can find a cut-off for a fraction of the cost

Re: Magnetic building system

The magnets with the metal on each side are MUCH stronger than those without and well worth the additional cost. My system wouldn't work nearly as well without the metal plates. I used 1/4" baltic birch ply for my pieces and built a jig for cutting the various upright pieces.

My system is built mainly based on information from the Airfields website noted above which I found very helpful.

Re: Magnetic building system

I tried to buy a sheet of metal from the metal supermarket last Saturday but their shear was broken. I ended up buying a 24x36" sheet from Canadian Tire. For magnets I bought 12 medium welding angle magnets for $2.99 each and 100 of the small ceramic magnets. I will tinker with it for a bit so see what works best. If need be I will add metal plates to sandwich the smaller magnets.

Re: Magnetic building system

I'm going to go this route also. I've been looking at this method for too long and I need to act on it! Lol! I'm going to build all my own fixtures also with some birch plywood.
Looks good what you've made so far there Randy!

Re: Magnetic building system

Great idea You'll love it and never consider anything else ever again...

I built the system like Airfield models. I used a solid wood door. I bought brand new 1/16" (16ga) steel - 24"x72". I keep it clean and oiled so it doesn't rust. I attached another 12"x24" piece to a cabinet door for building small models or sub assemblies. Both sheets of steel are adhered to the wood doors with contact cement.

Magnets are more strongly attracted to thicker sheet, without paint or coating BTW...

I used the magnets from Master Magnetics. They're a super company to deal with. After the initial 100, I ended up buying ANOTHER 100. Many I use without the wood jigs...just the magnets with plates.

I cheaped out building the fixtures and used 1/4" pressboard instead of 1/4" ply. I oil the edges a little to keep stuff from sticking to them. After several years use, I've had no problems at all. I also made the fixtures square on both sides (rather than one side sloped). Sometimes you can use both sides of the same fixture at same time.

If I was building the fixtures again....

I use the taller ones more often than the shorter ones. Ideally 5" to 8" tall. I rarely use the arms that exert down pressure, but when I do, I find them often the wrong height. I'd make multiple notches (or drilled holes like Randy's....even better), maybe 1" apart up both sides of the fixture so the arm can be set at any height, yet still be used to make things square to table.

(see discussion in Norseman build thread)

Re: Magnetic building system

I just came across these. I would have jumped on these if I found them last October.

I am assembling my own sandwich magnets at the moment. I used rolled steel so I am painting the pieces before I epoxy them to the magnets.

Re: Magnetic building system

The Airfields site has a link to a vendor that sells magnets at a reasonable price.

You don't need to epoxy the metal to the magnets, the magnets will hold the metal by themselves.
