Step 1: Material Required
We are using QuickFit clamps from www.frontierplay.com and galvanized steel from Home Depot wich is used to build chain link fences. The oar mounts, locks, and springs can be purchased from www.frontierplay.com or www.nrsweb.com.
The completed weight is only a few pounds more than a comparable aluminum frame on the market.
Time spent to build the frame depends on how you choose to cut the galvanized pipe. Other than cutting, this frame assembles pretty quickly. Our kids thought it was a lot of fun assembling the frame.
Step 2: Additional items for assembling frame
Step 3: Selecting your pipe
The top picture shows the pipe from Lowe's and the bottom pipe is from Home Depot. The price in our market was the same at both stores; however Lowe's pipe was a lighter gauge and seemed to compress more then we liked when the QuickFit clamp was tightened on the pipe.
Home Depot's 16 gauge in our market is what we are recommending because the pipe doesn't compress down when the hex nut on the QuickFit clamp is tightened down.
Step 4: Selecting you fittings
Orignally we built our frame with 90 degree elbows for all 4 corners but ended up going away from the elbows because they cost more and are bulky.
The best item is the QuickFit T clamp ($9.95) because it's smaller, better priced and accomplishes what we wanted: a low profile frame which wasn't heavy, yet was durable with easy to add options.
Step 5: How many pipes and fittings do you need?
You now have to decide what size of frame you want to build. Are you building a frame for a day trip, overnighter or extended river trip? Do you want a place for a cooler, dry box, drop bag, etc? Will the rower sit on the cooler or seat?
The nice part about these frames is they are interchangeable with Northwest River Supplies (www.nrsweb.com) aluminum frames and NRS's patented LoPro fittings (shown in picture). This option allows you to add fishing accessories, foot bars, and seat bars.
We recommend cutting your cross bars the same length as NRS's frame options so if you want to add a foot or seat bar it's easy to interchange.
If you really want to simplify the process FrontierPlay (www.frontierplay.com) offers a "Build Your Own" package option where you can select all the features you can imagine. It's really cool and worth checking out.
Step 6: Assembling your frame
You will have two rails ($8.75 each) which rest on the lateral tubes of your raft. We went with the 8' posts because the rails are the longest part of the frame. The cross bars can be shorter and cost us $6.98 each, you will need as many as your uses require.
There are two key frame measurements: center-to-center and flat length. Calculate the center-to-center measurement by taking the width (outer dimension) of your raft and subtracting the diameter of one tube.
We are showing two pictures. One picture places the frame directly on top of the tube using the above directions. We prefer to extend the frame a little pass the center which creates an easier walking platform and more frame surface area for securing your items.
For flat length, measure longwise along the relatively flat surface of a tube or pontoon; this measurement will indicate how long your frame can be.
We mentioned earlier that we recommend building the frame so it will inter-link with NRS accessories. NRS's frames comes in the lengths of 54", 60", 66", and 72". When cutting your cross bars subtract 1 3/4" from the NRS frame width. Example: for a 60" frame cut your cross bars at 58 1/4".
These pictures show a NRS foot bar being used with this frame.
Step 7: Putting the frame together
Slide how many fittings you plan on using onto each rail. Lay the rail on a flat surface and estimate where you'll want your fittings and then tighten the hex screw.
When one rail is complete do the exact same thing with the other rail. It helps to line up the second rail next to the completed rail. Tighten the hex screw in each fitting.
Make sure the fittngs are tightened on a flat surface to ensure the cross bars will line up with each other.
Now separate the two rails and insert the cross bars into the QuickFit clamps. Once all the cross bars are in place go back and tighten the hex screw.
You now have a raft frame. You can measure your cooler and or dry box to determine where the cross bars need to be located. I usually at this point crab the cooler or dry box and adjust the bars based on the actual fit of the cross bar. Make sure you leave just enough room to get a strap between the cooler/dry box and the cross bar.
Step 8: Accessorize your frame
It is our recommendation to purchase a NRS foot bar (69.95) because it's solid and won't rotate like a foot bar made out of QuickFit clamps can.
We have attached a picture of a foot bar made out of QuickFit clamps. We like this option if the bar is resting directly against a solid item such as a cooler or dry box. The bar won't rotate and works great for securing a cooler or dry box.
Step 9: Oar mount options
Now you need to decide what type of oar mount sytem you want to go with. You can go with an oar lock or a pin and clip system.
Pros vs. Cons of Open Oarlocks:
Pros: Oars slide easily up and back down the oarlock when pulling oar in to avoid obstacles. Easy to re-position mid-rapid if "popped out" of oarlock. Ability to feather blade (when not using oar rights).
Cons: More expensive. Oar can be completely released from oarlock if enough force is applied. Has more "play" which can be noisy.
Pros vs. Cons of Pin and Clips:
Pros: Holds oar and blade very securely. Less expensive. Hard to lose oar if oar stirrup is used. Quiet System.
Cons: Oars can be difficult to pull in when approaching obstacles. Hose clamps can damage oar shaft. Feathering blade is not possible.
Step 10: Final key accessories to add
If you want to really accessorize your frame, add the NRS cooler mount and NRS dry box mount ($65).
If you want to add comfort add the NRS seat bar ($95) and seat. There are two types of seats you can add. One is small and durable and easier to stack mutiple frames on top of each other for traveling ($66). The other seat is very comfortable and can get in the way a little more when transporting a lot of items on a vehicle. If you want the comfort, the bigger seat is worth the money $90).
Step 11: Congratulations!
Now get out of town and away from work and enjoy your new frame on your favorite river.
Have fun and enjoy!
Step 12: Improve Your Frame
We only found the need to use this material on our cross bar being used to hold a fishing thigh bar. The bar would rotate from the leverage placed on the thigh bar.
