That is a super idea and will make one myself also. As for my poplar, spruce, and aspen, I get it at the lumber yard in 1/4"x 2" up to 1"x4" with lengths of 4-6', just pick through it a find what I like.

Question though. I did not see where you secure the razor blade in the tri-stock tool. Also, when you write, "Dremel saw", I take it that you're using your Dremel scroll saw?

Press-on!

Maybe Dremel table saw..

They cut at a 45 degree angle, so the notches can be cut without drilling a hole first.

Gotcha. I misread the drilling of the holes were for the bolts and wing nuts. Now I get it.

Hi guys! Glad you like the balsa tri-stock maker. I must, however, be sure you understand that I did not come up with the original idea for this tool. The basic idea had been floating around in my "grey cells" based on the same principle used to split fuel tubing for use as cockpit coaming, that of drawing the material across a sharp blade. Somewhere, in a catalog maybe or hardware store or while surfing around on model sites or while day dreaming in the shop I had seen a similar type of tool (at least I think I did). In August, while needing some balsa tri-stock, I recalled this tool idea and then just went on ahead and made one up from scratch using what I had available. The result is what I presented here today. It is, in fact a swell idea that I wish I had fabricated a long time ago because it's handy and saves paying extra for balsa tri-stock when the material is required. The last thing I want to do is take credit for something someone else may have designed, but I can share with you a tool that is quite useful in the shop.

As for the Dremel saw that I use in my shop...it's an old Model 57-2 Moto-Shop scroll saw that I have had for some time. In fact it's the ONLY powered saw I use in my shop during model construction. I've included a photo of the saw.

The razor blade, for the tri-stock cutter, is placed between the two wood pieces across the opening size desired with the sharp edge facing the front of the tool. I just loosen the wingnuts enough to let me move the blade as needed and then tighten the two wood pieces together via the wingnuts, thereby capturing the razor blade in place. You might want to experiment a bit with the different razor blades being sold as some are real flimsy and will bend when used with hard balsa.

Soft landings,

Joe

Hey Steve, you were correct. I drilled the holes for the tightening bolts and cut the notches from the 3/4" square Poplar with my Dremel saw; basically I cut a V in each wood piece for each desired tri-stock opening.

Soft landings,

Joe


Edit: Oh...you were referring to the Dremel Table Saw...

I tend to make up my balsa tri-stock for this type of work from scrap square balsa pieces as I build. Thought I'd share a couple of photos of a homemade shop tool I fabricated and put together last August for just this purpose. The tool is made out of two (2) lengths of 3/4" square Poplar trim stock cut to 6 1/2" in length, two (2) bolts (1/4" x 2 1/4" thread length) with flat washers and wing nuts (easy to tighten) and a half side of a thin double edge razor blade. I cut the wood stock to length, sanded the wood and rounded the edges. Next I taped the two pieces of stock wood together tightly with blue painters tape as a unit in the form you see in the photos. Using my drill press I drilled the 1/4" holes for the bolts through both pieces of wood (2 holes required). Next I used a drafting template (from my Professional Draftsman days) and, laying the desired size squared onto the mating line of the wood unit as a diamond shape with reference to that line, I marked out the various squares with a sharp pointed graphite pencil. The taped wood unit was then untaped and separated and, using my old Dremel saw, the inside wood of each square was cut from each of the respective 3/4" square lengths of wood and lightly sanded as needed. The sizes were written on the wood with an ink pen and I sealed everything with a couple of coats of Swedish Tung Oil. When dry the unit was wiped down with an old T-shirt and assembled with the razor blade placed in position where desired for use in my shop. The photos should help you put one of these handy shop tools together if you wish. Enjoy!

Soft landings,

Joe

A couple of photos to show that I really did work a bit on the Spirit today...after the pumpkin roll and coffee breakfast and Thanksgiving Day dinner and pumpkin pie with whipped cream...and more pumpkin pie with whipped cream...have to admit I'm moving a bit slow. Hope you had a great day!

Fair Winds,

Joe
