While working on my RAF Curtiss Mohawk, I struggled getting straight 90 degree ends and edges on small parts. I've had struggles with this in the past as well and had long ago decided to purchase a sanding tool to help with this. However, the products I had found available for purchase tended to be very expensive and fairly cheaply made. The combination of high cost and poorer build quality was enough to keep me from making the purchase. I had considered making my own and even had started working on the design, but like most things these days, getting to actually doing it kept getting pushed back because of other priorities.

The Mohawk build finally pushed me to look again or build my own. I was fortunate in finding a tool from a small business owner, one that I had not heard of before. Fourmost Products. The owner offers the precision sander made from Alder wood and made to a very high degree of quality. Even better, the price was about half of everything I had seen prior.

The tool is designed and made in the United States which may be important to some. For me, the quality and design were the real draw. This tool has a guide which can be set to different angles allowing sanding of any angle desired. The sanding part slides back and forth versus other tools which require you to move the part back and forth. In my mind being able to hold the part completely still while the tool moves, is a superior design.

If you need the edge being sanded to also have a secondary bevel, their is a separate set of sliders which have different angles on the sanding face. All of the slides move very easily in the slider, while also fitting accurately, ensuring that the precision of the sanded edge is good.

I have no affiliation with this manufacturer, but I wanted to put this out there because it is a superior product and if you have the need for this sort of tool, worth the expense.

A very nice and helpful tool, Carl @clipper
Thanks for letting us know.
