shipping these kits from the US costs as much as the kit, and even with ‘6 day international priority mail’, I’ve had kits take over a month to get to their destination (and in one case, be missing all the small pieces)
So I am looking for people outside the US who are willing to get the arms cut (laser or waterjet) by someone local to them, order the small parts, and then sell the people ‘near’ them (i.e. someone in Australia to sell to the others there)
These arms work very well with the larger routers that seem to be the standard outside the US.
I do not want to collect any money or payment for this, I’ll help you by providing the files, walking you through things, etc. You find the place to cut the arms, you order the parts, you decide on your price, and you keep whatever profit there is

here is a dxf of the arms, modified to have a 6mm hole instead of a 1/4"
1 center bar (part 1)
4 horizontal arms (part 2)
2 vertical arms (part 3, the j shaped arms)
add to this
6x bolts (6mm)
6x nylock nuts (6m)
8x nylon washers
12x metal washers
(get washers with holes that are snug, not loose to the bolts)
2x master links for #25 roller chain (similar to https://www.ebay.com/itm/25-Connecting-Link-QTY-10-for-25-roller-chain-1-4-Pitch-Master-Link/321580064636 )
2x half links for #25 roller chain (similar to https://www.ebay.com/itm/Qty10-25-Offset-LINKS-FOR-25-ROLLER-CHAIN-25-ROLLER-CHAIN-Cheater-LINKS/371835414982 )
2x hairpin cotter pins (3/32" 0.90mm diameter similar to https://www.ebay.com/itm/Cotter-Pin-Hairpin-3-32-Dx2-1-2-L-PK25-2UJN5/132311526453 )
when you get the half-links, you will need to run a drill through them to make
the cotter pin fit through (the bars with the half link have one end smaller
than the other), put the tiny bit in a drill press and hold the link in pliers
and move the link over the bit, otherwise you will break a lot of bits. you want
to wiggle it a bit or get a slightly larger bit to make the fit a bit on the
loose side so it’s easy to put the pin through the link
you will have to run a drill or reamer through all the 6mm holes, you want them
to be a snug fit to the bolts.
you want the bolts to have a shoulder on them instead of thread all the way to
the head, this is so that the moving parts are not rubbing against the thread
(everything is hard enough that it should take years to wear, but not having it
threaded should make it last almost forever)
P.S. if anyone in the US wants to start doing this, I’ll be happy to sell off my remaining kits and let you take over shipping them. I’m doing this to help people improve their machines, not to make money off of it.
