I would add a oil pump for bar injection of oil on both ends. If it seems worth it tracks overhead to place over log and hang mill down over log. fix bearings to high speed it would be nice to increase chain speed to what normal sprocket produces 10k or so.
Thanks for your answer. The belt doesn‘t slipp? I build my own sawmill with a honda engine (Gx 390 14 Hp). But i build it with gear. I took a old chainsaw and build the Engine in it.
You need skip/hyperskip but regrind at 10°. The granberg didn't work well because it wasn't skip chain and it's a very wide cut. You need full skip microchisel or semi chisel rip chain on 25"+ and hyperskip on 30"+ you are way over so you need hyperskip semi chisel chain, same chain as crosscut but 10° so you can regrind crosscut chain. You can go to 15° for Softwoods and some use 0° in full chisel. The main issue is the fact you're using full chisel chain, that's why it's vibrating and not efficient, it will work really well when you get some suitable chain on there. Needs constant bar oiler of course, use decent chainsaw bar oil as it's stickier and won't be going off so you won't need so much, just constant. Chain needs to be tight, no nicks.
Great mill! How many teeth does your chain sprocket have? and what pitch is it? I have built a similar mill with a 17hp opposed twin briggs but I am using HTD belts and pulleys with a 2.4:1 ratio so the shaft is running at 8600 RPM with 3600 RPM on the motor, this is close to what a chainsaw runs at - my chain speed is 22m/s with 8t chain sprocket. I found that at this RPM V belts would not work as they kept slipping and would burn out. I have standard NSK UC205 bearings and they do fine at way over the rated RPM and are cheap to replace. I have also drilled the end of my bar just pas the tip to add bar oil through a fitting into the slot - you should look into this as the oil needs to be in the slot not just dripped on the chain - I use to do the same drip system but burnt out bars fast. I did the same thing to my chain skip chain is the way to go!
Thanks for the info! I don't remember off the top of my head how many tooth the sprocket is. Its the biggest possible sprocket that I could fit without derailing the chain off the bar. Works just fine but definitely could be going faster. You are right, the bearings are cheap so I might change the ratios to get more chain speed. I will probably have to change belt types to avoid slipping with a higher ratio. I don't use the machine a ton, but I'll probably consider upgrading my oiling setup. I wasn't totally convinced the drip feed was adequate but I saw other guys use it so I gave it a shot. I also started just pouring some water on the bar while I was milling, I don't know about your setup but that chain seemed like it was getting pretty hot.
my next project. you've gpnne further than i was thinking on my, but, have you cut any seasoned oak logs? i have a bunch from storm a couple of years back im wanting to cut beams out of
Go ahead and speed up the chain it’ll just shortened the life of the bearings you’re going to change them anyway it needs to run 10000 rpm keep having having fun 🤗
Hey, i have just one question. How does it work? Why did you the power from the engine to the chain by a String? I think the power from your engine would be much bigger if you would do it by gear.
It works the same way belt driven lawnmowers work. As long as the belt isn't slipping you are transmitting power. If the belt was slipping, then you could argue that a direct drive with driveshafts and gearboxes would be more effective.
I'm watching this video 2 years into the future in 2024. If you're still running this chainsaw, mill get rid of standard chains and switch to carbide chain. You'll thank me for it
Have you chainsaw milled with a carbide chain? I was always curious to try one but wasn’t sure if the expense was worth it. Also wasn’t sure about the added hassle of having to sharpen a carbide chain
@budgetbuilds5722 I haven't milled with one but I got one for firewood processing a few years ago and it's still cuts 5 times as long between sharpening. There's a reason most blades carpenters use are carbide or tool Steel. IT just cuts better longer. But a bit of a science to sharpen.
GREAT JOB ' WITH A FEW TWEEKS YOU WILL GET IT TO WHERE YOU WANT IT . TRIAL AND ERROR IS HOW YOU LEARN GREAT IDEAS .
Very informative video, looking forward to seeing more from you.
super helpful, thank you can't wait to build myself something similar
Great job on the mill, I’ve got similar needs and may end up with the same project.
Thanks! If you have any questions just let me know

hey Ii like ur chainsaw by chance will you make plans for your mill
my next project. you've gpnne further than i was thinking on my, but, have you cut any seasoned oak logs? i have a bunch from storm a couple of years back im wanting to cut beams out of
Awesomeness
Amazong bro!!! I am making one right now with 190cc electric start and 32” bar. Think it will have the balls?
It will probably do just fine! I had more than enough power by far

I like a lot about the design except I want mine on a trailer frame and rolling carriage

Do you have more videos from your sawmill by work?
Yeah, if you look at my channel I have a playlist of 6 videos building the mill. This was the 6th and final video from the series
What was the time frame it took to mill that lumber
About 30 minutes to mill a slab with a fresh chain

Hey bro thanks for the response! Whats your Instagram? Also update us on the carbide chain
Yeah I’ll let you guys know how the carbide goes! I don’t share my social media accounts though just for privacy purposes
@@budgetbuilds5722 ok but can i email you?
