cooks roller guides!?

So my ceramics are getting worn and I either replace em, or try rollers.  So I ordered a set of standard cooks roller guides so I can fab and weld them in place before the saw goes back on the track for spring sawing after the thawin. I was wondering if anyone has already put these on a HD36?

 

Thanks

So here is how I fabbed up my new cooks retrofit 1 1/4 8 way adjustable guides!  I had taken off the old guides and thier brakets than I copied the bolt pattern and made new mounting brackets to attached to the roller guides.  So if I wanted to switch back or have a failed roller and need to saw i can switch back to ceramics in about 15 min.

also if anyone goes this route cooks has good videos explaining how to set these up and the importance of the blade angle! so if you buy these also buy or make the blade alignment tool.

I will not be able to report the performance for a month or so as I have other projects to do, and its still cold out!! 

I will update this post as soon as i dial them in.

I run the standard Norwood rollers and get good performance from them, but... the roller on the operator side I have issues with building up with sawdust/gum when running softwood. Then it stops rolling and I worry I will flat spot it. This has been going on all winter, I try running my water and lube concoction in front of the roller and behind it, still happens does anyone else have this problem and what do others run for water mix. I use a lot of windshield washer fluid. Most of my milling is done at minas temps and I mix fluid to match the temperature. I do like the little stops on the rollers in the pics that might help all those little pieces of stuff that get caught between the roller and blade. I know I jump around must be my A D D.

This is a problem I have not found as well I havent got it on the saw bed still doing stuff to the mill.  one other thing I would wonder is what is the dia of the norwood rollers? these ones are 2" If thats bigger i would think it would help.

Zehrbrox, I will measure them tomorrow and let you know. I think part of my issue is the rollers are exactly inline with the wheels so not much blade tension/pressure on them to give a little more friction against them. I am on my second pair of rollers now but got a lot of running out of the first pair, over a hundred hours of actual saw time on them. I find the roller shoulder wears a little more on the driven side than the operator side and I swap them after awhile, I also press the bearings  out and pack them with grease once a year or so and got really good run time out of them.

My rollers have 1/8 " maybe 1/4"  down presure on them and only replaced a bearing in 1 after a few hundred hrs. they now have over 500 hrs. and still going . Checked yesterday and the one on the operators side is turning but feels like it could use a new bearing . I used a sealed bearing and will replace them with sealed bearings. I run very little water most of the time. I mix 1/4 gal. of window washer fluid with 5 gal. of water with 1/4 cup of pinsol or dish detergent. If crap starts building up on my blade or rollers I give the blade a shot of wd40 with the motor reved up a bit and it cleans thing right up. I also have a drip line with chain oil diesel mix I can use for real pitchy logs.

I was talking to someone a month or so ago, and he mentioned something about lubricating rollers and hubs.

If you don't tend to lubricate as directed, USE SEALED BEARINGS or such. If you do grease as suggested, then by all means, use something that required grease.

The difference is only about 10% to 15% in service life.

 Pitch build up on the rollers comes from pitch on the blade. So to prevent build-up on the roller, you have to keep the blade clean. Simply dropping water on the blade before before the roller isn't going to help much unless it's petroleum based. The way to keep the blade clean is to wipe the blade. 

 

 After I switched from ceramics to rollers on my HD 36, I had trouble with sawdust building up on the rollers even with pinesol. I noticed Cooks sawmills have a felt wiper that rides on the blade. Here is my solution.

The was no down pressure so I shimmed down the stationary roller bracket down 1/8" . Then switched the roller over to the the wood block. My homemade block allows me to move up ,down, in, out, and tilt. I removed the top ceramic and stuffed a bundle of plastic broom bristles in the hole. The bristles ride on the blade and keep it perfectly clean.  The hose is simply tucked in the top of the bristles. Without lube the blade and roller will load up, but as soon as I turn on the water and Pinsol, the blade and rollers come clean in a few revolutions.

good idea and point i never noticed that wiper on the cooks mill till you mentioned it.  thanks, I am going to look at welding onto the bracket I made, for a wiper holder.  I am thinking of a very generic cleaning product... like a hard sponge it looks like the cooks mill i saw had something like that. make like a pocket where they would fit in and can be changed out quick and easy.

So we had a few nice days and I was able to try out the rollers. I would say I am very happy with them I was cutting through 20-50yr old hydro poles and there was minimal to no blade dive!! and my boards were very accurately cut to the desired thickness.  I added a 2x2" square tubing and cut SOS pads for a blade wiper! (thanks to Wayne for this tip). I also made adjustable feet that are lagged to the wood block so I can put a string across the bunks and get them all the same level! Very happy with the upgrades!

nice, it snowed again here lastnight so i still gotta wait to get to my mil, but my parts should be here this week!

 There's nothing more satisfying than a project that works out.  Bolting down the rails is a good idea, the mill tends to walk when you bang big cants around.

 How much did the guides cost?  The rollers and bolts cost $200.00 from norwood.

good work on those rollers!  I see you were able to make a mount for the gaurd as well.  I never bothered with it as my guards plastic hand bolt broke and never bothered to fix it.  have you thought of making a wiper for the sliding side?  its easy to add later as you just need to remove the bark blocker plate and fab something up.  I never tried it without it.  After Wayne brought the wiper to my attention I just put it on!!  

Let us know what you think of them!!

Nice Mods...for those who have added rollers, how's the noise level.. I read a while back, (somewhere) they are significantly louder then the ceramic setup. That said we should all be wearing hearing protection anyway..

I like the wiper idea.. my biggest issue with ASH is the build on the blade.. other woods dont seam to be near as bad.

Zehrbrox.. I may have to take a drive and see this is action..

that looks great!!  it will work great as well I've never had cleaner blades...  about that yep when this super storm is over rick i'll give you a tour! and I don't find the rollers much louder than the ceramics.  as well i was gonna get a hold of you my blades r running low!! once the weather is better!!!

 I think the rollers make more noise but it's about the same as when the ceramics would move out of adjustment. 

I'm glad the wipers work as well as mine do. I cut a few  boards out of black locust last week with the lube shut off. The blade and rollers loaded up after only two boards. Turned on the lube and the blade was clean as new in the first foot of the next board. I've started a wiper crusade, once you try them,  you'll never go back to just drips and splashes.

my first test cuts with a pitchy pine after installing cooks roller guides and the cooks lube drip/wiper system, blade is still shiny new, i would highly recommend the mods!!
