Took the BIL out for a run last weekend and realised I need side rollers.
So here we go. The side rollers are those white wheels on the bottom of the mill frame verticals. The idea is that when the chain pulls the mill up against the side of the log the rollers contact first and there is less friction generated making it easier to mill. I got the idea from Railomatic and have a similar setup (but only single wheel) on my small mill.
Here is a side shot. I wanted the wheels to be able to get as close to the cutting plane as possible for regular cutting or when slabbing the topside of the log.
When cutting the bottom half of the log the contact point changes and the log rubs on the vertical support up near the rails instead, so the wheels can be moved up the vertical to stop the log doing that. Here is a shot showing just one of the wheels moved up near the rail on the the closest vertical.
Finally here is a close up of one of the wheels. The construction is basically a turned ally flange/bearing on which rides a teflon wheel. On top locking everything in place is a brass collar with threaded holes for 2 locking hex bolts. All bits were raided from the scraps bin at work.
Cheers
