Nice, is it possible to make a universal sprocket to eliminate changing, just a thought.
I can change over completely in less than one minute. Would you believe I'm dumb enough to not verify the hole size on the .325 rim sprocket to see if it fit the same shaft? lol. I'll look today. No hill for a climber. 3/8" pitch is the workhorse around here and I'm a self-centered bastard when it comes to my saws.
As for the space saver function, What about a setup resembling an engine stand?
Make the pivot tube as long as the distance to the opposite side from where your bar
is bolted on now. Much shorter length of a pivot tube and you'll have a wiggler
that wont stay tight (use at least a pair of *fine* thread tension/clamping screws for holding it in position)
Then put the top plate back on an continue the hooks & accessory zones.
Good ideas. I'm thinking of a spring loaded pin to pull and drop the bar or captive threaded tubes welded to the channel on the back side of the bar. Rigidity is a stipulation in whatever gets built here.
Great Job!!!
- To keep the chain from moving on the bar while filing, maybe have a stop like on the chain grinders? It you pull the chain forward it will flip up the fall down behind the cutters so when you are filing the chain will not move away from you.
- To make tighten/releasing the chain for quicker chain swaps, maybe something like a spring loaded chain binder?
_ Is the post adjustable height?
There used to be an Oliver plant here. I'm curious about your user name. lol. Oliver also makes some killer woodworking shop equipment. That's a different outfit up North though. Or is it your name?
The chain doesn't move now when you are filing. When a guy struggles with wobble of the drive links during filing, he is only trying to milk a dull file for too many cycles. A new file @ $1.15 every five or ten chains will rectify many ailment.
I feel this could be made compatible with any filing jig, though. I could build in a guide for angles no sweat, or a stop or a robotic tool which milled each tooth in a line bore fashion. Trust me, Brother. "Be Relentless," is my mission statement.
I like the binder idea a lot. You are one hell of a farm-styled mechanic and it shows. I don't want anything that can spring loose and bust knuckles, but there is daylight in that tunnel. Your idea is grounded solidly and on the drawing board.
About post height, it is made for me at my height. I have an old drum throne in the shop that also is very comfortable for this setup. The way it is mounted means when you do the opposite site cutters, you take a step around the jig. You will love how you can keep both hands on the file and push/pull with the fingers of the front hand off the opposite side of the bar.
I had questions regarding the crank handle accessibility from the right cutter side at first. But it is evident that it works better from behind than in front. Any issues will be resolved there when I convert to motor drive via a small gearbox which will turn the crank.
