Hi all, Im looking for a good belt sander. There’s a lot out there but I’m looking for a specific feature: The ability to let the belt follow the fillet and the tubes. I have a hard time finding on the than can do that, the belts usually sit very close to the blade, making it hard to let the belt follow the smooth turns.
Im looking for something more like this:
Any recommendations? I can use pneumatic and power.
I basically just cut off the front and made a new end from some scrap aluminium and I cut away the bits that hit the belt. Probably my shittiest yet most effective tool.
Here is a photo of the original thing:
I got a Milwaukee M12 cutoff saw and a kit off of ebay to convert it to a band sander. There is a guy in the UK that sells his with the contact arm. It’s not a cheap way to go though. I was looking at how to electrify my dynabrade, because they use a lot of air and I don’t have a big compressor. Even the rebuild kit for the dynabrade die grinder costs a lot. And all the good electric die grinders would be a pain to adapt to the dynabrade structure. They are also expensive.
I have thought about making it so I can adapt dynabrade contact arms to my sander. I don’t need a dynabrade for fillets. I hate to file so I have worked on making my fillets clean enough that they don’t need a lot of filing. It’s so easy to cut into the tube with a dynabrade. When I was at Trek in the '70s I used to hate it when the guys with the dynabrades would just go wild and undercut the tubes.
If this were a popularity contest, then I think the air tool belt sanders would win. Most people that use a dynafile type of narrow belt sander to sand brass fillets use those. However, I didn’t even know that Milwaukee now makes a battery powered narrow belt sander. Thank you for pointing that out! I would totally go for that. Less hoses for me to trip over in the garage! Even if the battery doesn’t last long per charge, it wouldn’t matter to me. I don’t really like spending forever filing my fillets smooth anyway, and consequently take lots of breaks which I could use to recharge the battery if needed.
One feature I’d consider whatever brand you choose, is enough clearance and torque to run 3M Scotch-Brite belts. I’m not very familiar with all the choices available, but I use a Dynabrade, you can change the arms for different needs and belts. I found the Scotch-Brite belts to be by far the most useful.
