I doubt you can buy the materials for building the wheels for the price listed on eBay.

Cutting 316 stainless with a hacksaw doesn't sound like fun either. Nor does drilling it without a drill press sound like fun.

I never said you didn't do it. So what was your total cost $$$ investment, and your total number of hours spent fabricating?

My wheel setup could not be purchased to I had to build them, as no one offers a 49mm wheel, let alone anything capable of handling a 4.2m (500lb) boat over sand. I have almost $400 US dollars invested into them with probably close to 8 hours of fabrication time. 316 stainless is hard to cut and drill. Then again I used 3/16", and went with a functional design that is sturdy. A lighter weight boat doesn't need nearly as much material and strength.

Seriously, check the pics in the link earlier and here:


Beach launching

It isn't rocket science: (per side) measure and cut one piece of U channel. Measure and cut one piece of box (eg that's about 3 minutes...). Drill two mounting holes in rear face of U to bolt to transom, then matching central pivot holes in U and box. Then upper and lower locking pin holes in U and box.

One more hole at base of box for wheel spindle. The odd washer, spacer, bolt nut, squeeze of mastic here and there. Maybe an hour or so? Materials cost - beg, steal, borrow, buy but a fraction of your US dollars (400?!) for sure, maybe 30 to 40?

I guess though most of us are talking 75 kg all in small SIBS, your 500 lb. is trailer territory.

There are some nice commercial sets out there but making your own is very easy and economical.

I have the small fold-up wheels on my SIB.

They work OK but as mentioned there is not much ground clearance, so the keel does sometimes scrape on the ground.
However after four years of use there is no damage to the boat. I would say they are fine for a smaller SIB (ours is 2.85m)
One issue is, if you forget to raise them once in the water, the boat won't plane....and for a minute you sit there wondering what is wrong lol

hi be carful if you don't buy the pneumatic tyres as the hard plastic ones are not as good, for beach launching as they get stuck and sink.

Hi, Been making my own too this week. I thought most of them looked pretty poor value, so i made my own with lawnmower wheels, a bit of chromed plated mild steel, a few odd nuts and bolts , and my old welding skills. I found an old shop clothes rack with one tube sliding inside the other, enough to make a dozen pairs of wheels. Still needs finishing , but here are some pics, and a link to the one i used as a guide to my wheels.

Course, they will need to be kept an eye on for rust and they need a tether because they will sink seem strong and ready to give them a go at the weekend.
