How long ar your back / log stops?
« on: October 04, 2017, 07:43:36 am »
I started designing the bed for my mill and came to a crossroads. I am wondering what length are everyone's log stops? I am thinking since my mill is setup for 36" log that the stops should be at least 18".

Whats everyone think? How long are your backstops from the bed?

   The side supports on my mill are about 12" tall when fully raised. My mill is designed to cut up to a 32" diameter log. You can always add extensions if need more height - I never have. I'm thinking the taller they are the more likely to try to saw them off. ;D

The taller the stops are then the need for more clearance at the bottom to ground level when you drop them. Assuming you are building that style of stop that does not swing down.

My plan was to make them pivot and connect them all together so I can raise and lower all 4 with one device. The divice is still undecided whether I use acme threaded rod a lever or something completely crqazay.

I'd steer from threaded rod. Sawing logs is not clean. Dust, dirt, sap, pitch, bark and debris. Imagine all that binding in your threads even in one place let alone multiple location.

was not going to do full length. Just long enough at one end to get full movement and use a bar to connect everything else.

Thanks Jeff that is a good thought I did not think about.

Heh, I think I finally see a use for the 100,000 stupid shock boots I kept throwing away :)

No matter what length you make them you will try to cut them off😲 Trust me I have a couple of times. 12 inches seems to be about average.

The ones on my lt70 are just under 14.5 inches. They go straight up and down.

On my LT40, with the blade set at 11", the blade will clear the top of the stops with about " to spare!

Mine are 12" high and pivot. I would not gang them together so they operate via a single device. Even if you have only 2 backstops sometimes a log lands on the mill where one of the backstops encounters a knot or bulge and being able to lower/raise one backstop is a big help.
If you plan to skim the log then it's a moot point.

Thanks for all the responses.

KelLOGg that is something I keep wondering about. I am not sure I want them all to work at the same time but I also don't want to have to walk the full 24' of the mill every time. My mind is still going crazy with ideas on what to do for that.

I really appreciate everyones help and comments. they really help get my creative juices flowing.

Usually you're using only two backstops at a given time and they're probably 6-10 ft apart. It's nice to have extras along the length of the track, but they all don't come into play on every log.  Many times they want to be at slightly different heights depending on what's sticking out of your log.  If they're not hydraulic, you're going to have to tend them, so you'll get some exercise.  Sawmilling presents lot's of opportunities for cardio-vascular and strength training.

On my sawmill, the additional (inside) side supports are geared more toward handling short logs, and that is the only time that I ever have to raise mine.  For normal sawing two are sufficient for me; one on each end of the log.  Of course much depends upon the length of the majority of the logs that you will saw.  With 24', I could visualize a manual side support toward the end beyond the powered support.  I would not space the powered side supports further apart than 7' for handling 8' logs.  The log clamp would be centered between the side supports.

The great majority of the logs that I saw are from 8" to 16". 

I would make the side supports no taller than 12" and have square tubing or pipe to slip over them for turning the odd shaped etc. log.

Thanks MM thats very helpful.

Maybe what I need to do is just make the stops and have them setup on a pivot but not link them together until after I get some sawing under my belt and I see what works. I am sure this is going to have a huge learning curve. But, I am also sure I am relly going to enjoy it.

Hmmmm could have all of them on separate levers. Thats a lot more material though.

Uh oh there goes my crazy thoughts again....

So pineywoods your saying I should make them a 1/4" longer than I need? :)

I've got all four of mine hooked up to the same hydraulic lever, so 4 up 4 down. 
The first one is about an 1/8" higher than all the others so that if the band clears it, then it will clear them all.

oooh. I like the 1/8" idea. I am guessing you only have saw marks on the first one? You ever find times when you wish they weren't all connected?

my timber king 1600 has the swing type and they all work together, Id say the are about 14 inches tall, which is plenty tall enough for me and I have put some big logs up. I would defiantly say keep them all together, there is no way in hell id want to adjust each one individually! But If I built this mill, I would not make them swing, Id make them move vertically up and down. The swinging motion is constantly hitting knots when I go to lower them. And I raise and lower mine a lot. I raise them every time I roll the log or cant. They are much sturdier in the completely vertical position, which is why you want them there when you roll stuff around on the mill.
If I can't fix it, I don't want it.
