I am going to build a log arch. It will pick up a 28" log. It will be around 7' long. I have 2x3 box 1/8" thick to make it out of. If anybody has any pointers or can give me some tips that would be great. I've never used or seen one so i don't really know much about them. I also will be using a hand winch, tell me about placement of it and anything else.
going to build a log arch but I know very little about them

These two were built by the father of a friend of mine when he owned a sawmill.

I've made a couple and have threads on each if you want to search my name: log arch and log arch v2.0.
Regarding winch placement, the line just needs to be vertical right at the strongest portion of the arch. Whether you bolt the winch directly above that point, or mount it on your top tube and use a pulley to redirect the line seems to make little difference. Make sure you build a point to hook the winch line to on the arch itself. Small trees can be picked up with winch alone (line hooked to itself), but looping your winch line under the tree and back up to the arch will (although halving your line speed) basically double your lifting power.
I welded on slots to hold chain on my second arch and would suggest highly suggest them.

2x3x1/8 might be a little lite for material...

I disagree, with the caveat that it's designed properly to distribute load,i.e. bracing. My first was 2x3x3/16 and is ridiculously heavy for it's purpose. My second is 1 3/4 .120wall HREW and the arch part hasn't ever looked fatigued.
Now my top tube has bent, due to loading in a direction it wasn't meant to (also catching a tree with the tire at speed), but with a suspension brace, I'd imagine it would've been fine (or something like Logrite does on theirs).

Ya Timbrjackrussel. That's another good video. They just want so darn much for any log arch. Seems like a fella could build one for a couple hundred dollars using all new material.

How about starting with an old hay rake as a frame??

That's a good idea. There's a busted one here sitting around getting rusty.....
Do yourself a favor and don't hook the cable from the winch to itself! TSC sells axle straps that would be perfect for smaller stuff. Short chains for everything else.

Guido,
WOW!
What a collection you have there. Are these machines at a farm park by chance? I see a smoke stack so I guess someone was using steam at one time.
Thanks,

These belong to a couple of friends of mine and can be seen at our local tractor show. Come on up to Richmond the third weekend in September and join the fun.
