Color....is there any color other than dark machine grey???
a pulley in the middle wont make any difference at all, the winch should go there instead, in theory the one cable will work, and if it is well balanced so it will in practice but it can bind, carriage not traveling parallel, its simple geometry but I wont insist.First off, thanks for the input. It is good to get ideas from others. Now, I am going to disagree with the single cable not being able to lift equally on both sides. I may be wrong, but I think I am going to continue with the direction I am currently going. I have seen a number of them on the internet that seem to be doing the job. Now I may add a pulley to the top center its not a big deal. I'm not sure that this will change anything. Yes, right now I have a "u" configuration on the cable. If I add one to the center I'll end out with a "W".
I don't think I am worrying too much about the color, but it is something I want to address at some point. To me it is all part of the building process. I did that when I restored my Mustang.
As for motor location, I do expect that the engine will be more to the drive side than the center. I was not worried about it being located in the center of cross member, but rather more on center to keep it for being too heavy front to rear or tippy. Hope that statement makes sense. As for the belt I don't feel that the belt will interfere with the cut. I will be installing an idler that will also act as a clutch and will push on the belt rather then pull. I have noticed a number of builds that pull on the belt and allow for less belt contact on the drive pulley this will increase the potential for slippage.
As far as cost goes I think that building your own is much cheaper. I don't count the time since I am retired and that plus it is for me, is the reason I am building this mill. As for cost I doubt that the cost will hit the $1,000 mark. The gain is, I get a larger engine, more capacity if I need or want it, additional clearance for cuts (thanks to you guys) and the satisfaction of making my own.
so you are not going to be using a centrifugal clutch but rather a lever/pulley clutch ( that is what I was implying as a third pulley for more clearance of the drive belt ), I was debating installing an idler on the hf to accomplish a similar effect, mod the guards to get more clearanceForgot to mention that I did some machine work for the mill today. Looking through my old pulleys I found a few that could work only they needed to be bored. Both pulleys are cast iron I will be using a 3 inch on the engine. The crank shaft is 1 inch in diameter and the pulley was 3/4 so I bored it to 1 inch and broached for a new key. The driven shaft is 1.250 and the pulley hub was 1-inch so I am now boring and then I'll do a 1/4 inch keyway. Once I have these two done I can get a better visual on engine location. Who knows maybe more pictures.
That mill won't work unless the tracks are exactly parallel on the same plane, if they aren't he is going to have a twisted board. That is way way more trouble than I would be willing to go through to get some lumber.sounds like you are on the right track, and yes I have debated putting my own touch on the HF mill, like welding the components solid, we'll see how it looks / holds up once I get it together.
I honestly prefer the centrifugal clutch but I was debating installing an automotive idler pulley and a longer belt and move the drive belt away from the cut in a similar manner, cut back the guards, etc,
when I was debating building one, something like the logosol ( I believe ) from New Zeland with one track on the ground and one 4 ft high was my choice.
this was an interesting Idea, I was considering something similar as far as locking down the log ( screwing at both ends ) so I can turn it easily and raise the log rather than lower the cutting head, this will give you a cut parallel to the center of the trunk and not the taper, well that was my concept and than I chickened out and ordered out of a catalog, unfortunately I am not retired, work a day job and trying to build a house out of pocket, hence the mill, thou I may at some point tweak it a bit, figured a few mods wont take as much time than building from scratch.
the 4 post is more solid but as mentioned a proper design/gussets, tubing size will do as well
