how much weight will two layers of 3/4" plywood hold?
I have two groups of 3, 2x8's and one group of 5, 2x8's. I am running the groups of 3 for the sides and the group of 5 down the middle. Each group is 7' long and am planning on 4' wide. Do I need two layers or will one layer work? The ramp/table will need to hold 1300lbs. when I ride upon it. After I get off bike it will have approx. 1000lbs on it.

That's overkill . 4 2x6's , spaced on 1 foot centers , run the ply wood crosswise , that is the surface grain should be crosswise to the length of your ramp . One layer will hold that load , use 2 if it makes you feel better . My last ramp was 3 2x8's tied together with 2x4 cleats on the underside . Worked swell to load the bagger on my trailer . -- Snag In 1775, the British demanded we give them our guns. We shot them. |

A lot of the utility trailers we have here in Nebraska have floors and ramps made of expanded metal. The frame is angle iron. One advantage is the mud and water disappears all by itself. I don't know if that makes us lazy or efficient. There aren't many who haul bikes or 4 wheelers in their pickups. |

Thanks for the reply, I was worried about a fall. It really hurts when you get older. Thanks again M.

At 70 years, I know when not to ride. But your are right it can get slick, I had to repair my roof in the rain and slipped several times before finishing up. I am a very fair weather rider now days, so the yamahammer stays under the car port. Thanks again.M.

What are these groups, how do they relate to each other, and how to the 2x8's within a group relate to each other, are they at an angle, a ramp, what do the 2x8's do, what does the first group do that the second group doesn't and vice versa, and most important, what is the point of all this? In other words, ask a question everyone can follow. |

It is nice to have more storage space when traveling. I hope to do more of that now that I'm retired. One could buy a really nice car or pickup for the price of some of the Goldwing and H.D. trikes. There sure seem to be a lot of the "new" Can Am Spyders for sale. I think I saw one that was a 2016 for sale with 0 miles advertised. I don't remember seeing one on the road.

The Ryker is also interesting. When I went to the CanAm site to see if the Ryker is still in production I noticed they're all sorts of woke. There isn't a dealer in town Or I might take a look. There is a Polaris dealer but the Slingshot looks like a Lotus Super 7 that lost a wheel. |

I think I saw one that was a 2016 for sale with 0 miles advertised. I don't remember seeing one on the road. Mine's a 900 Kawasaki Vulcan with a Lehman Storm conversion. There are 3 CanAm Spyders here within a 2-block radius of my house, all owned and ridden by women. Two of the women are older and retired. I see them head out on most weekends if the weather is nice, following their husbands who are riding 2-wheeled motorcycles. The third is a younger single lady who rides her CanAm to work most days, rain or shine, year round, and likes to ride at night and on weekends. If you get her started on why she rides and what she likes, you can plan on being there a while. I haven't seen an HD trike around here, except passing through on the Interstate. Those things tend to have two wheels in the rear, which is way too dangerous for me. You couldn't pay me to ride one of those on the highway since they're only stable when going in reverse. Two wheels in the front is the way to go, when it comes to trikes. As for me, I'm still riding my old 2007 FJR1300. It works for what I do. |

The Robin will loose every time when it comes to stability - and kids fal;l off of tricycles quite often - I know I dumped mine often enough as a kid and had it up on 2 wheels too often to count. Braking into a turn is almost guaranteed to dump or at least destabilize a single front wheel trike particularly if a short wheelbase with a moderately high center of gravity. |

I went to an ATV race where some guy showed up with an old three wheeler. It wasn't high speed since it was held in a rodeo arena but the guy spent a lot of time putting the thing back on three wheels after he dumped it. Then there is this thing: https://en.wikipedia.org/wiki/Piaggio_MP3 At the height of the scooter craze there was a dealer downtown. I was walking around one night and stopped to look at the models. I always wanted a Vespa -- when I was 16. My father put his foot down; motor cycles were fine something with 10" wheels was not fine. Anyway the guy tried talking me into a test ride but I declined. Like a sidehack, it looks like a motorcycle but it definitely is NOT a motorcycle. If any emergency situation came up I would do absolutely the wrong thing. I looked at trike recumbent bikes a few years back and they come in both configurations with the two in front being called tadpoles. They made more sense to me than a two wheel recumbent. I'd rather not fall over trying to get moving on a hill. |

It helps a lot that our trike is based on a Sportster Low model . I've tried a bit to lift the inside wheel , haven't managed it yet and I'm running these nearly as fast as on the bagger (mine has had the rear suspension modified to eliminate swingarm movement in relation to the frame) . Or maybe my balls just aren't big enough ... I was talking about situations where you're doing emergency braking, especially coupled with trying to steer around an obstacle. Heavy braking and sudden steering inputs are a recipe for disaster when you only have a single wheel up front. It's just physics. Sure, emergency situations don't come up every day, but when they do you won't want to be on a vehicle with that configuration. |

I am running the groups of 3 for the sides and the group of 5 down the middle. Each group is 7' long and am planning on 4' wide. Do I need two layers or will one layer work? The ramp/table will need to hold 1300lbs. when I ride upon it. After I get off bike it will have approx. 1000lbs on it. -- For full context, visit https://www.homeownershub.com/mainte...d-3108818-.htm So one area has 3.5 ft between joists, the other 1.7 ft. I'm sure you can look up some tables that show deflection versus spacing. My guesstimate is that one layer is plenty for the shorter span and that you need more joists on the other span. This can help if you enter the proper values. https://woodbin.com/calcs/sagulator/ Neat, what did we do prior to the Inet? I still have my slide rule; somewhere. -- Tekkie |
