Evening everyone!

I bought a Rockler mobile base that requires you to use your own material for the spacing bars.

http://www.rockler.com/power-tool-mobile-base-hardware

White oak was suggested but metal was the most likely choice. It is for a Jet 8” Jointer.

So, steel or aluminum 1.5” tubing? Not sure exactly where to find that either. Home Depot has 1/2 or 3/4. Wonder is using 4×3/4” tubes (would be the same size then) and there would be more steel/aluminum material there. Thinking like a steel cable, bundles of small cables are stronger than a solid.

Thoughts?

I have a HF base, similar to this.
I used off-cuts from an LVL beam, ripped and crosscut to size.
I’m sure any wood should work.
Maybe not pine or balsa wood!!!

Metal suppliers often have a pile of “drops” (cut-offs & shorts)....
That should be cheaper than buying “fresh” stock.

I have the HF model, I just sized a 2×4. My 12” band saw sits on it great

The strongest solution that is also cheap is to laminate some pieces of 3/4” plywood together to make your rails. Just make sure the edges are facing up for the most strength.

I’ve used oak, and, as Brad suggested, plywood. No probs either way.

Brad and Randy. That makes sense to me. If I can find LVL locally (Denver – Colo Springs) then I will go with that.

Norman – the jointer weight 411 lbs so a 2×4 won’t cut it. I might check in with Woodcraft today and see if they have anything.

I was also thinking that I could try white oak or a strong wood, with reinforced 1.5” aluminum strips bolted on the vertical sides. Might look cool if I stain the wood. Might as well make this look custom if I have to do the work.

I wouldn’t necessarily purchase LVL for this project.
Perhaps a local construction site may have some off-cuts.
I really like the idea of laminating plywood….

I have the HF version and the first time I just used 2x material, the weak link was where the foot lever caster was mounted, the wood twisted when the lever was pushed so it hardly lifted at all, I had it on the long side of the base so switched it to the short side which improved it, I then rebuilt it with white oak that worked excellent
You could possibly use oak for the lever side and 2x for the rest
Multiple pieces of steel would flex to much unless welded together but would make drilling the hole for the bolts difficult, you’d be drilling through the edges of 4 pieces

I have always used 1 1/2” steel tubing. It does not have to have a very thick wall. Homedepot and lowes are worthless for such things. Go to a steel supply shop. They will have exactly what you need and it will be a lot cheaper than Home Depot. I think most steel shops generally charge a buck or two a cut so bring the exact dimensions you need and save yourself a lot of headache with a sawzall or hack saw.

I used free oak from pallets… worked great and didn’t cost anything.

Cheers,
Brad

I would go with their suggestion and a strong hardwood like oak or hard maple.

Brad has a great idea if getting hold of hardwood is difficult for you.

You can always get some 1X oak from a big box and laminate them up to 1 1/2” stock

Thanks guys.

I picked a long 8/4 hard maple stock today. I will cut it to size Wed when the jointer comes and even sand/stain it just to make sure it is pretty! Should be strong enough and the lift will be on the short side (thanks tom).

The extra stock will go towards some jigs I need to make and a small workbench organizer.

Thanks again.

Thanks for the help. I did get hard maple and cut it to 1 9/16 to make the material for the Rockler base. It is definitely sturdy and I think it looks pretty good as well. The base installs easily but you really need to make sure you get a straight hole so the screw line up. It rolls well enough on a garage floor with 410+ lbs on it.

I would probably buy it again in place of a bandsaw base for more money.
