This would work great for flattening sides before binding

We use the larger version of this tool for working cutaways and some initial neck heel shaping- the larger is about 7-1/2" in length, but that smaller tool looks like it might be a little easier to control! There is also a smaller diameter version sold by Grizzly that pops up with the larger tool listing - also looks handy!

Glad to know someone makes these. Control that power!

I have the Grizzly 7-1/2" sander and it is an indispensable tool. My only regret is the diameter is a smidgen too big to fit inside the cutaway. If they had a second one with a slightly smaller diameter I would add it to my tool set in a heart beat.

For those interested Industrial Abrasives has the same "hoof " sander for a few bucks less along with a good assortment of sleeves for the sander. I got it and really like it for the waist and cutaway sections where a scraper or flat block won't work.

Also this is slightly smaller (2" vs 2 1/4") than the larger grizzly sander so it might work for your cutaway.

These are useful tools. I've got both of the grizzly models. Only complaint is the non-standard diameters meaning you must buy sleeves from Grizzly.

There is a downside to using these for side flattening. They can actually "round" the sides because they are pneumatic. Light application pressure only. Scrapers work best. But in a cutaway, not many options exist.

These tools are cushioned contour sanders, so the air pressure in the bladder is adjustable and the sleeves made from more flexible material than standard oscillating spindle or drill press drum sleeves. We usually use this tool at close to the default 90 psi that the air distribution system in the shop provides for sanding cutaways and closer to 25-30 psi for other work, so worth setting the bladder pressure before each use for the task to be accomplished. At higher pressure , the drum is almost like a spindle sander's sleeve - the work stays flat and there is little or no give. At lower pressure, the sleeve has quite a bit of give, and allows compound contours curve contours to be worked, such as found in the heel area. Despite the availability of grits from extra coarse to very fine, we use the tool with fairly coarse sleeves for getting rid of the big divots or coarse shaping- a cork-on-CPVC-pipe sanding block with P150 and P220 is what we use for final leveling.

I've got a question for some of u experienced users. Please post an inflating valve that actually fits the narrow space. Those for inflating tires are a pain to use. Thanks!

This work?

This is from a while back a home brewed version

We use an inexpensive mountain bike air pump to inflate our bladder sanders -- we lock the handle in a vise so we can easily engage and disengage the pump from the sander.

Similar to this:

For what it's worth, if you use a mountain bike pump like the one in the link you will probably be un able to get much past 60psi. They are not designed for high pressure. One designed for road bike tires or a floor pump will get you past100psi. One for air pressure in a mountain bike shock will take you to 250psi+ but will take a while.

David, since the maximum recommended pressure is 8 psi, for us that is not a concern.

I hear you Ken.
I only mentioned it because Woodie G said he runs his at 90psi sometimes. He's either using a different rig or on the edge of some serious excitement.

I wouldn't put 90 psi in mine! Maybe Woodie knows something I don't

Yeah, they're are not rated for high pressure. I was just looking for a simple way to inflate

As the boss suggested, line pressure is 90 psi, but we have regulators at the drops we don't use all of it very often. What I should have said was that we inflate the tool until it is very rigid.

I can hear that - please stop snickering.
