Topic tags/keywords: question

All,

I am trying to figure out what would be the best option for ‘axles’ on an outdoor glider.

I think that a bolt would not offer enough support and would wear the hole in the wood out of round, possibly elongating it and making the chair not glide smoothly.

Am I over thinking this? I wanted to try my hand at a glider, the though of 2 pipes nested seems to work in my mind, but the use of bearings seems excessive.

Thoughts??

If you’re hung up on using wood, try Lignum Vitae.

I’m planning on using scraps and was hoping to get by with 2×4’s for the frame. Basically I’d like to work out the details and not spend a ton of cash on something that will be left outside.

Just get some nylon bearings from your local ACE hardware that fit over your bolts. These are nylon tubes about 1/2” bigger in diameter than the bolt. They are fairly cheap and will protect the wood. Make it glide better, too. Make the bolts long enough so the wood members don’t rub against each other and put 3 or 4 washers on the bolts between the wood pieces to hold them apart. Unless you weigh 1000 lbs, bolts alone would probably last 5 years. With the nylon bearings, you should get 10 years at least (providing you paint it).

I guess it should be stated that the bearing part of the bolt should NOT have threads. Threads would quickly eat up most any material besides metal. An metal wouldn’t last as long as it would if it was designed properly.

If you want bearings and want to build your own brackets, inline skate bearings can be had on ebay for less than 50 cents each. Get the sealed ones though.

Rance,

Thanks, I was thinking they might work well. I’ll check.

Did you ever find a solution? It would seem to me that bronze bushings might be good solution over nylon.

You could trying counter boring the pivot points and install bronze or brass shoulder bushings with stainless through bolts. they would be a lot cheaper than bearings and wear practically forever.

Sorry Ratchet you already said that. Great Minds Think Alike!
