Re: Possible Solution For Tracked Equiptment
Are those on the vario not tapered?, every pad I've seen is well radiused and tapered. If I ever get my pic's uploaded, you will see what I have done with mine. What is the track pitch on that machine?

Re: Possible Solution For Tracked Equiptment
catmack your more then welcome . best way to load pics is through an off site photo account like photobucket .
I think if we get enough of us going on this we can produce a bunch of sizes .

Re: Possible Solution For Tracked Equiptment
I was able to post at my other post, see attached link. IH, I have 12 sizes layed out with a size common that will also cross-scale. I started with my 1/8th then 1/10, 1/12 and 1/14. The samples you see, will each have four different pitches all together. In order to make this hobby more affordable and accessible to more people, a standard will have to be set and I am willing to take on that roll if it allows more people to enjoy it and is needed. I hope I am not doing this link wrong.

I may make another grouser pad just like this with more some details and see what machining cost will be. I got en e-mail form my machine shop today and they said they are just wrapping up the quote and should have it within a day or two. I may send them another grouser pad that is a little more scale and complicated to see how much it will cost. But the good thing is, is that if this pitch that I am currently using is what you guys can use then I can make multiple different grouser pads that will bolt onto the link with just unbolting the old one and bolt the new one back into place making this a very universal system!

Re: Possible Solution For Tracked Equiptment
Chris, that looks really good. Are you going to do a dozer pad as well?

I agree, making a unit as universal as possible is one of the most important things to keep in mind. What kind of steel did you have in mind? In the photo, what size machine is that? Colin |

catmack, Thats exactly what I was thinking, if I had a set of links that could be used with any track pad you want then it would make things much more simple. I would like to use stainless but its not cheap! so probably will be going with just a standard carbon steel that the machine shop would have, not too sure on the exact compound. I'm not too sure on the size of the machine in the picture, it was just a picture Azonic sent me to use as a reference Chris |

Re: Possible Solution For Tracked Equiptment
A question about material sticking to the pads. Would spraying the pads with something like Pam, the non-stick cooking spray or some silcon-based spray, reduce the problem?

Re: Possible Solution For Tracked Equiptment
Its good to see someone take the bull by the horns with the track situation .I have a set of nylon ones on my TD 25 and can see some wear with the short amount of use on mine and the scale appearance could use a bit of work as well...I like the Idea of the two peice track link or could even make it a 3 peice with the bolts and pins holding the two links together .Probably simplify some of the machining ..Your Cad/cam work is very good ..Hopfully one day i can master that as well ..which one are you using and are you pretty happy with it ?

When you say you have noticed wear in a short time, what is short 2 hours, 10 hours, 40??... |

Re: Possible Solution For Tracked Equiptment
After looking at my posts here, I feel like I broke the rules. Chris, I apologize for dumping my thoughts on your thread. I should have commented on my thread. If the mod or admin. could move my comments or delete them, what ever you see fit, I would be greatful. This is not how I envisioned contibuting to the hobby?...again, I am sorry if I offended anyone here. Colin

Re: Possible Solution For Tracked Equiptment
sparkycuda - I had thought about that as well, but I would think that It would be taken off in a matter or seconds in the dirt. I also thought you could apply a non-stick teflon coating but that would not look to scale.
tracksntreadslou - Thanks you! I felt it was the best way to get things done sooner than later as In September I will begin full time school and no time to help out by doing this. Catmack - No worries, no harm was done and you apologized so it is all good! Update! Have a little update that could be seen good or bad depending on how you see it. I got a quote back from a machine shop to have 225x 3-piece track links made, all CNC machined from an ISO 9001:2000, ISO 9001:2008, QS:-9000, ISO 14001:2004 certified machine shop ,made from 7075 Aluminum with a black hard anodizing. For $14.20 USD, which is a little much so I am going to work with them to reduce the cost and which will require switching to 6061-T6 Aluminum. If this happens to be the best path to be taken I will beef up the current design to withstand years of abuse. Also just wanted to ask who would really be intrested in purchasing some tracks? I would need a pretty strong guarantee as the machine shop likes to do higher quantity orders and with a higher quantity the price per unit will drop. I can post dimensions if people would like. They are basically a direct bolt on setup for Vario machines and whatever other use you want! I cannot guarantee any price right now as Im still working hard to make it affordable for everyone to have nice CNC metal tracks!! Please let me know so if you would like some so I can get an updated quote for everyone! Thanks everyone, Chris *Edit - Also just want to let everyone know that if many people decide they would like some I would prefer to do large orders every so often rather than small orders of the same item constantly, as It will save time, and most importantly money, as I can guarantee if you come to me later asking for say 75 track pads I will not be able to give you a good bulk price due to the machine shop prices, as I have to at minimum cover my costs.

Re: Possible Solution For Tracked Equiptment
Did Kalle tell you how many links in the Vario? (I don't want to crawl around in the dirt to count for myself, if at all possible ).
Depends greatly on the final price... if you can't get even close to cutting that 1st quote in half, it's not worth it to me just to have metal tracks for the sake of a scale appearance.

Re: Possible Solution For Tracked Equiptment
I think he said 55 per side, don't quote me on that :P
Yea thats exactly what I am thinking, I revised the parts to simplify the machining process so we will see how that goes. I want to keep them as scale as possible without killing everybody's bank! I will let you know how it goes! Chris |

Re: Possible Solution For Tracked Equiptment
I was guesstimating 60 per side, so a bit less is better yet.
Thanx man for your research on this, hopefully something positive can come from your efforts of it.

Re: Possible Solution For Tracked Equiptment
Chris, your efforts are noble and of good intent. This is what it takes to make progress and I think this is what this hobby needs.

Re: Possible Solution For Tracked Equiptment
It certainly won't be all for nothing if it doesn't come to fruition, at the very least it'll be a good learning curve for you in terms of a feasibility study for your chosen profession & as well as the rest of us who contemplate other what if scenerios.

Re: Possible Solution For Tracked Equiptment
Looks like I may be able to get them made for about 9usd. But i need to order 700 track sections. I'll post all the details tonight when I'm home from work

Re: Possible Solution For Tracked Equiptment
Okay so here's what seems to be the solution and current state of this "project" if you want to call it that.
Good News The machine shop can have a whole link made; grouser bar, two link, connecting pin for $8USD. But I would need to charge probably around (not 100% yet) 8.50-$9USD each link to cover my the shipping cost, bolts and C clips. Bad news, kind of To get this price per piece we need to have a total order of 700 links or more. It sounds like I have about 330 links, Half way there, woo hoo! These, like mentioned before are a direct fitment to the vario equipment. Also the material list: grouser pad - 7075 Aluminum track links - 6061-T6 Aluminum Connecting pin - Carbon steel This looks like it will be the final design. I had to change the links a little bit to reduce cost but I tried to keep the grouser as scale as possible. Any questions let me know so I can get this going asap!! And if your intrested or know anybody who would be intrested send them my way as it looks like I wont have these made very often with the larger quantity required. Chris |
