I am going to be getting a wide belt. I am wondering what your process is for sanding. I have heard about people going back down to 100 or 120 with the orbital after wide belt and work their way back up to your finish grit. I dont have much experience with a wild belt. Thanks
There is good info in the knowledge base on this subject, I suggest you start there.
A description of your wide belt would really help. Platten or drum contact? One belt or two? What grit do you intend to use? Solid wood or veneer sanding?
We have a 2 head but that really doesn't matter. We sand to 180 with the wide belt then finish with 150 with a random orbit.
We do a mix of paint and stain finishes.
The beauty of a wide belt is how evenly it sands. If its not a door so you are not creating cross grain scratches finishing straight out of the machine is an option.
Using a widebelt is a science. We took a Stiles class long ago and it really helped. What abrasive to use in what circumstance. How to diagnose problems. Well worth the investment.
Rich C has asked some great questions and you need to make sure you know what to look for.
We have an older scmi that works great and I over sand all to 150 then RO with vacuum at 120.
Our dust collector is a grizzly 220v quad bag on a stand so we can pipe right in with a 6” drop/fitting.
I have the air shut off right on the machine and a blow gun that is plumbed off that. Our collector has a remote to turn it on right next to the machine control buttons
Anyway we sand flat at 80, then start climbing while dropping our platten at 120 amd take 2 passes then 2 passes at 150.
For our machine it doesn’t take much drop once we get to the platen ad the sanding surface area just got bigger than just the drum contact.
I hope this helps some
