Transfer Seat Part 2

[rydog1130]

Never would have thought about a boat motor system. That’s some serious “out of the box” thinking right there!

Randy

Yeah should be strong enough to run that cyclinder but compact enough I can hide it behind a panel or under the floor!

a little more progress today, drilled mounting holes for the inner slide and will tap those later! Next us getting adapters or new ends made for the hydraulic lines and replacing the spur gear on my wiper motor

 

[rydog1130]

A little more done today. I added the spur gear that mates up to the rack that will hopefully drive the seat in and out of the truck. My other two vehicles have a similar set up where a spur gear attached to the same window motor powers my seats forwards and backwards via a gear rack. Well I thought I could pop off the gear on the motor and then pop mine on, not the case. First the the diameter of the new gear was about 1/64 of an inch too small so Todd and I had to find a drill bit the correct size to mill it in order for it to fit. Then we had to remove the pinch points on the gear face of the motor so the whole drive gear and spur gear came out. It was pretty easy to take apart. I thought maybe the old gear was keyed on the shaft to keep it from spinning but it’s actual locked in via a plate that sits in the nylon gear. We sat and discussed several options on how to attach the new gear since the new one would not fit in the locking system and was too small to be milled. We thought about making a collar to fit over the new gear and milling the sides so it would fit but that’s just too much extra work. So we slid both gears on the shaft and Todd tig welded ten together. The extra length will work now w/ the motor as it gives me room to mount it to the outer box without cutting into it! Here’s a few pics

What is the connection between the hydraulic system and the spur gear on the wipers? Kinda got my curiosity up.

There’s two motions to this system. 1. Moving the seat in and out of the vehicle which the wiper motors driven gear /rack system will do and 2. Up /down which the hydraulic system will do because it will require some force once there’s a load on the seat (me) lol !

 

[Speedrdr]

Thanks for explaining that. You’re gonna post a vid clip when it’s done, yes? Lots of moving parts and pieces to coordinate! Sounds like it’s going well.

This is some great engineering! Looking forward to seeing it operate.

Thanks once I get the inner slide together I’m going to load test it to see if there’s any flex. I’m hoping these 500lb drawer slides are substantial enough to hold my weight. I’m thinking that since the slides are boxed in it will prevent any twist

I trust that you’re gonna static load test before you hop on and try it out. Learned the hard way with a climbing deer stand that my weight was more than the attached parts would stand. Lol

Ok so today was kinda of a make or break point. Either this thing was going to work or not work once we put weight on it. We got the inner square stock mounted and it seemed to slide in and out pretty good. I was trying to think of the best way to test it out and thought about clamping it with a board on top to the car hoist arms but my dads mustang was occupying the hoist. I looked around and saw the boat trailer and said that’ll work. We clamped it on there and extended the tube out and drum roll……….,…………………………………………….


It worked lol, it held my dads weight without a budge and he’s close to 200lbs I’m assuming since these are rated to 500lbs it will handle the seat and me just fine. Here’s some pics!

Only thing I noticed is my inner tube is mounted on the slides on a slight angle downward. I though we had it correctly spaced but the end of the tube must of slipped about 1/8” - 3/16” so I’ll need to take out the screws at the end and adjust it then drill and tap some new holes. If I don’t correct this it’ll potentially cause my gear rack system to bind up

Not much progress lately, had a big parade in town this weekend so we tossed all the original transfer seat stuff back in to get it on the road! I need to adjust the inner tube a bit, here’s a few pics that shows how off it is.



And some parade pictures!!!

Ok had a little hiatus on the project with summer coming to an end but finally getting back to projects with newly acquired time in my hands (kids are in school!) I fixed the gap issue! These slides have a vertical oblong hole so I drilled a small hole then put in a self tapped and removed all but the rear screws on the slides. Adjusted the height then tightened down the self tapers, marked new holes and drilled! I also mocked up the hydraulic cylinder that will power the up down portion of this unit. Looks like too much was added on as the 4 link isn’t sitting parallel. Will need to have Todd cut and reweld or get a unit with a threaded end! Anysways hope to have more progress but next week!

Is there any chance you could/would post a set of drawings (I would pay) and specs of this item??? I am certainly interested in seeing the final design in action. As an aside, would mirror image work for the passenger side??

Hi speeder I posted up specs earlier in the post, yeah you could assemble the parts in reverse fashion but once they’re welded together then that’s it. It would actually require less work than the drivers side because you won’t have to drop the floor pan like you will with the driver side.

 

[rydog1130]

No real updates dropped elevation arm and fam back off with Todd. Going to have him shorten it so it sits correct. Will post more here shortly!

 

[rydog1130]

Kids got sick, I got sick ….finally able to get the control arm back! Todd removed about 1/2” and now the 4 link sits parallel! Now hopefully between hunting season I can get this thing finished! Lol

 

[Speedrdr]

Looking good! Hopefully everything will be road ready before season opens.

So I was on hiatus with this project as fall hunting took priority for my free time! Winter is here and there’s no ice to fish so that means bronco seat is back online! This is the unit that will lift or lower the seat once it’s out of the vehicle.

I cleaned up all the contacts and dumped fresh oil in it. I couldn’t figure out the wiring on the switch that controls the relays as they were cobbled together with wire nuts. We took a short cut and just bridged the relays with a screwdriver to test it out and I’m surprised it seems to work well with no binding. Next will be to load test it with some actual weight! Hopefully the video will work!

 

[Speedrdr]

Looking good! I’m betting that the “weight test” is gonna go as smoothly as video shows…at least I’d bet on it.

I’m hoping so!!
