Oh well, Openbuilds having been out of v slot for months, is now out of stock on everything but the v slot. Which makes v slot pretty much useless… Thinking of going a different direction here…
You gotta pre-order. Except for v slots, openbuilds other stuff are available on inventables, Amazon or can be 3d printed or plasma cut anyway. They have the plans available for you to print and do with.
Yea, was right in the middle of an order when half the stuff suddenly showed out of stock. And iventables stuff isn’t quite the same, and/or is over priced. But I had already ordered some parts needed for the open build (pulleys) from them…
Plus if I’m going to use V wheels (as apposed to the solid ones), I’m not going to use them in a v-slot. Would be better off using them on the grounded edge of a piece metal…
I’m thinking of a fixed gantry setup, made up of scrap metal and the metal v wheels.
Just pissed that I waited all this time for him to get the v slot in, only for him to ignore the other parts needed to actually build a machine based on his parts…
@Mat_Helm
Which machine were you going to build?
@Paul_Frederick One of my designs using openbuilds drive system. But the big thing I needed from him was 2080 and/or 2060, plus solid v slot wheels…
The biggest issue I have is that I’ve talked with the guy here on G+. I asked back in Jan if the April 15th date that one of his distributors had posted as a resupply date was accurate. He said no, it would be back in stock way before then. Of course we now know that his distributor knows more than he dose apparently. And now, right as I’m finishing up an order, after spending a couple hours working on it, half the stuff suddenly shows out of stock…
Point is, openbuilds is not something you can count on. I’m thinking of using his idea, but making my own rail using a bit to cut the v slot on a router table. Or using a knife sharpening grinding wheel to cut a v groove onto a flat piece of metal, and using v groove bearings. But all the time and thought I’ve put into openbuilds design is pretty much wasted I think…
@Mat_Helm
Going to do some garage machine shop work are you? I don’t know anything about those fancy extrusions. Except that some folks build with the stuff like it is 2x4s or something.
Yes, a 2 by that cost between $6 and $10 a foot for the 2080…
Wondering where @Peter_Fouche1 got his rail, and what size and price n such from his post here on the 29th… Also how that build is going…
Just posted on the (18 member) Openbuilds Community page, and got a quick answer from Mark Carew…
“We are stocking up now and will have more then enough in a day or so ;)”
@Peter_Fouche1 You caught my attention with that second link. Had the rails, ball screws n all… Pictured…lol But of course it was just for the Ball screws and hardware. I’ve actually got a few things on my watch list from that guy.
The openbuild would be around $250 to $300 with shipping. The only place I would use the vslot stuff is where movement is needed. Was a 1500mm 2060, 1500 2080, 1500 2020, 25 vwheel kits (half of which get eccentric nuts for “preloading”). a 1000mm x 8mm ball screw ( would cut it to 3 or 400), bearings and end caps, screw nut, 7’ of GT2 belt and a couple of 20t 5mm timing pulleys.
So to answer your question, the most expensive axis being the Y, would be 50 to 600mm X2 of 2080 ($20), 8 X Wheel kits @$3.95 per ($31.60), Belt $2.00, pully $7. misc $15, so about $75 bucks… hmm, maybe Y isn’t the most expensive axis…
But you can see my interest in their materials…
Very good link Peter. Would love to see a full detailed post about what you get for your project. What are you building btw?
Ya know, we could send over a Goldwing and save you all that work… ;p
Except for the turning faster than a sports bike, that describes a goldwing. It has heat n AC as well. Also a trailer hitch that I’ve seen tow a small 1 person camper (think coffin with windows…lol) http://motorbike-search-engine.co.uk/classic_bikes/goldwing_sidecar.JPG
But I know it’s probably cool. As a rider, the only concern I would have was how hard that hi back bucket seat would make it to get away from the bike in an accident. And maybe those remote steering bars snagging a testicle in a collision…
Wrong picture link I think there.
Having grown up ridding dirt bikes and had a few collisions on the street as well, I have to say that at no point have I wanted to stay with the bike. With the exceptions of a couple of high sides that went a bit too far… lol But in a t bone, if you weren’t launched, wouldn’t you just do a face plant into whatever it was you hit?
On the remote steering. Have you thought of hinging the brace in the center, with maybe a magnet to hold it to the tank? That way, it would simply hinge upward and away from you in a collision.
I know you’re an engineer type like myself, so I’m sure you’ve ran though all the scenarios already. So if you think it’s safe, I’d get if a go if I were there…
@Peter_Fouche1 Made me think of you… ;p
@Peter_Fouche1 Yea that was from the 30’s I think…
