5 Hole to 4 hole adapter plate?

[dave88]

I found sweet vintage Lib Tech I really want to ride but I want to use newer step in bindings. I do not want to drill holes and use t bolts as this board is in really nice shape. I think it is a 92' it has the fiery skeleton reaching towards the moon and has the early (burton etc.) 5 hole pattern but I want to use 4 hole bindings. I love the way the early Libs ride.

Does anyone know where I might find adapter plates for this?

Thanks!
Dave

Machine your own or suck it up and drill it out. Once the 4 hole came out, all the old "standards" just got dropped.

Ah, Innercourse, I take it. I managed to land a vintage plates for it. Otherwise, youre stuck with it.

The best solution is to build some out of 1/4" aluminium plate. Some say that 1/4" plastic with stainless stell inserts can be ok, but I have my doubts. If you are a heavyweight or a hardcore rider, than either T-nut your board or build an adapter out of 1/4" aluminium (6000 or 7000 grade) with stainless steel inserts.

Slightly off topic to thread but we are talking adaptor plates,




If any one has a pic of their home made adaptor plates please post.

I have an adaptor plate project on the back burner for a different problem.
( a few older but mint carvers that i can not stretch stance past 20.5 ")

I was leaning to 1/2" thick 6061 ( ease of availability ) and tapping instead of steel inserts, having a hard time finding metric tee nuts aound here,

Is 6061 t6 Al tapped out to m6 with 1/2 inch thread contact going to be strong enough for an adaptor and 200lbs on top. ( prob 6-8 bolts per)

Was thinking of applying "drillium" to reduce weight in the 1/2 inch aluminum.

Pictures, hints,or suggestions appreciated

thanks

Just remember to lock tight the 5 studs. And use some sort high density foam or in my case rubber to augment board flex. That set up was for Proflex bindings the 4 bolts are counter sunk underneath and glued in place. It is 7000 series alloy which is a bit of an over kill but it's only about 4mm thick. You could drill a few holes here and there if you wanted to lighten things up some. What ever you do don't tap into the alloy. Some stainless tapered nuts could be counter sunk in to the base if you still want to use the bindings std fasteners.

if you use 1/4 / 20 screws with the standard T-nuts available at hardware stores. Just don't get them mixed up with your other binding screws.

oh yea, the older lib tech are 1/4 x 20!!! NOT METRIC!
