« Part 55: Seasoned Maple Boards Part 56 of Woodworking on a Half-Shoestring series Part 57: HF Accu-Link V-Belt on Hitachi C10FL -- Wow!! »

Just a quick update on several issues that have been forcing all of my attention.

Hitachi C10FL Table Saw Issues
I mentioned earlier that the saw had been neglected for a while and so there was a lot of cleaning, adjusting and correcting to so. Tonight I managed to resolve some of the vibration and noise issues when running it. When I previously adjusted the blade direction to be parallel to the left miter slot, I didn’t pay attention to the back trunnion support’s relationship with the trunnion. Not only can I adjust the support side to side, but also front to back. I had it spaced out from the trunnion allowing it to bang front to back. My bad. That’s been resolved. I also checked the belt tension while running, looking in from the opened back side. It tracks straight and doesn’t show any wobble. The motor isn’t hanging up when I lift up on it. Whatever is causing the vibration will have to wait for a later date.

The front measurement scale on the right side for the fence is as accurate with the true cutting capacity as the eye can see. Cuts appear to be cleaner than before and a square shows no light on the cross-sections. I think this is as good as it’s going to get with the environment I have to work in.

I posted a question in the forums here about correct table height for each person, as if there was a formula or rule of thumb. So far no one came up with anything on that, but good thoughts were passed my way. Tonight I spent some time thinking about whether the height was really an obstacle I needed to hurdle or if this was just a matter of mind over matter. I think the latter will be the case. I still don’t like my arm being above the blade when pushing stock past the splitter. Since this table top is also deeper as well as higher than the cheap contractor saw I have, it stands to reason that my short arms are the issue.

The last matter is dust collection. The dust collection port at the bottom is for a 4” attachment. I need a 4” to 2-1/4” reducer to fit the hoses coming off my shop vac. Harbor Freight has one for $4.00. This weekend the wife and may be heading down that way for a movie, in which case I’ll swing by and pick up one. Otherwise, I’ll order it and wait the ten days to have it get here. Why not get one from Rockler? Ten dollars more there, plus even more shipping, and…it will still take more than a week to get here. I sometimes shake my head at how in today’s world wide operations it still take Pony Express speeds to get things here from a hop, skip and a jump away. Go figure. So for now, I have the back panel off the chassis and I vacuum out on occasion.

Tomorrow I work on building a miter saw station. I decided to remove the door to the small room I mentioned before and building to fit a replacement that will have an alcove for the back side of the miter saw to fit into. This will allow the working end of the sliding miter saw to be on the bench, meaning I can keep the bench shallow in depth, running left and right of it for the width of the wood wall. This will cut down on the dust (I will have a dust port at the bottom of the plywood alcove for the vac) as well as save space. More on that after it’s built.

There may be another thing that causes some vibration. Sometimes the belt cause it. Try to spray silicon (just the automotive type is fine) on the belt. Running if you can safely do that. If not several places and then run a while.

I use this on vehicle belts all the time to keep squeals etc. and run smoother too.

My first thought on this was the belt not tracking right (I didn’t have the motor pulley correctly on the shaft) or slipping from the motor bouncing up and down or just not pulling the belt tight. I ran the saw while looking at it from the back side using a trouble light. (Yes, I was smart enough to stay outside of the chassis) and the belt ran so smooth I couldn’t tell it was running. I’m thinking there is play in the trunnion or a dry bearing. The blade cannot be moved side to side, so…I just don’t know. Maybe I am expecting too much from it. :/

Tomorrow I am going to measure the circumference of the v-belt and order the appropriate length of Power Twist Plus V-Belt to replace it. You may be right about the vibration coming from the belt. Who knows how long it has been run without the motor pulley seat screw on? The belt may be slipping enough to cause the problem. If anything, the Power Twist Plus should quite it down and make it run quieter.

Another cause of vibration is the V-Belt having a “set” to it. In other words, the belt develops a memory of being on the pulleys, and that tight radius, and then that causes a bump twice a revolution of the belt. You might want to look into the “link-belt” it is a series of interwoven pieces that do not have the V-Belt memory issues. You can also get it at Harbor Freight, since it looks like you are headed there anyway.

Thank you, Colorado Goose! I was able to pick up a HF Accu-Link V-Belt in our trip down to the Triple-Cities area yesterday. I just finished installing it and YIPEEE! The blog post to follow with show the results. This solved the vibration problem in spades! :)
