My board sensor question (yes, another board sensor question)

[Don Butler]

Just got back from watching the Youtube video on changing the belts.
I see I will have to disassemble the machine to make sure I get everything I need to get the job done.
Does anybody know what the difference in price is between the sandpaper belts and the rubber ones?
This doesn't look like it's beyond my skill set. :->

Basically $17.00 vs. $140.00 http://store.carvewright.com/home.php?cat=283

I had a similar problem yesterday my board sensor was reading 48 so replaced the board sensor and its up and running, listening to people here on the forum I had extra parts.... thank gosh I listened !!!!

[Don Butler]

Thanks.
I think my mind has been persuaded by the economics!

on my second machine I wanted the rubber belts it wasn't 10 minutes into using my new machine that the bit broke and tore the sand paper belt I replaced it with rubber belts and don't regret the choice I think for economic reasons going with the rubber belts is better for the long haul...

Hmmmmmmmmmm.
I'll think upon it!

The new traction belts arrived today. The guide posts are cleaned and lubed. The head crank mechanism (clutch) is lubed. the new belts are in. After everything was assembled the head pressure was checked.
It's consistently going up to 95 pounds.
Called the factory, they said to align the guide posts.
I did that and rechecked. Still 95 pounds.
Did it again and rechecked. Still 95 pounds.

That's liable to tear up my new belts, isn't it?
I don't see what else I can do to reduce the head pressure.

Try removing crank handle and seeing if there are any washers on it. They would be on it before the spring and may blend in to the handle. If they are there you can remove them, each one adds about 5lbs of head pressure.

Thanks Chris!
That did the trick. Two washers I didn't see before.
Took 'em out and it's cranking 80 pounds consistently.

ps. Now, tomorrow, I'll see if, with all this misadventure, I can carve the job I tried to do in the first place.

Well, here's another thing.
When I started the machine for a small test run it measured the board a;right, but when sensing for the bit the Y truck wouldn't go all the way over to the bit plate.
How do I make that adjustment?
