Home made rotisserie built with grill kit from Home Depot and a few saw horses
Just setup the heater and motor on a timer, cuts off when done!

Tube slotter I built, sold it and building new and improved version
I could slot anything from 3" to 12"

Switchband sander, for sweet, straight, smooth ends

Most of mine are low cost and as little build time if possible, the tube slotter was the biggest project for jig building.

I go to Payloadbay.com, enter my specs, print one out at actual size, tape it to a piece of foam core, cut it out with a matte knife. I just mounted my fins for my Level 3 cert rocket that way.

Bar napkins are integral elements in history, creativity and ingenuity. Some of the greatest ideas of mankind are so inscribed. Unfortunately, they are usually lost and never recovered!-Thus, travelling near the speed of light or turning lead into gold still are categorized respectively as science fiction and alchemy.
Please don't lose those napkins, I look forward to the plans.

(LOL) My poor attempt at humor,

John,
You should know that just about everyone on RF should know your building and design prowess, wish I could spend a day photographing the inside of your shop!
I wish I could make more time, but family and then work take priority.
I don't have time making elaborate jigs and such I would like.
I try to find existing parts and pieces to make what little jigs I have.
I am trying to make time to share all of my ideas and hopefully, like you all, we can help others to have some neat stuff!

I finally broke down and made this jig from 1/4" foam core for use on my AGM58 which has 4 fins. There was no way I would be able to eyeball the large fins straight.

I first laid out a cross with a builder's square. Then I used a circle cutter made for cutting card stock to cut a snug 4" hole.

Then a hole saw to cut the relief holes. Finally my table saw cranking the blade up through the foam core. Worked like a charm. The tip to tip dimensions between any two fins is accurate to less than a millimeter!

Unless you really like to do the layout part, here is a link to a website where you enter the diameter of the body tube, fin span, thickness and number then print the fin guide and glue it to foamboard and cut it out. Its very easy. http://www.payloadbay.com/index.php?page=Tools&action=FINGUIDES

That's why I like thread like this. I like to think outside the box too often but foam board is awesome, the whole while I made them out of 1/4" plywood.

Have you though about making those for sale? The shear pin jig is awesome. I also like the Epoxy holder.

Ditto. I made my first fin guide from 1/4" plywood and thought what a pain in the @$$. Then I noticed other rocket builders making them from foamboard and have used that ever since.

I think you were replying to me. If so, yes I have. Contact me if you're interested.

Here's another invaluable jig I came up with for working on rockets during a number of construction phases. I used to struggle with the typical PVC tube cradle which always seemed too flimsy for holding components while drilling, tapping, sanding etc.

I welded a couple of steel rods to a long 1/2" bolt and threaded a sleeve for the bolt to run in. I welded the sleeve to a common wood clamp and covered the rods with tight fitting rubber tubing. The clamps can be positioned on the edge of my workbench to accommodate anything from a 6" long avbay to virtually any length of tubing or a complete rocket. It will also hold a nosecone because of the "grippy" rubber tubing. The height is fully adjustable and a locknut prevents it from moving. When doing internal or external epoxy fillets, I can level the rocket by adjusting one of the cradles with a spirit level sitting on the rocket so the epoxy flows out level. I also use this setup for drilling and tapping holes.

Here's my "Jig" for re-assembling nose cones.
There's only a few commonly available nose cones in 2.6", so sometimes I need to cut one down to size.
This jig makes sure that when I put the parts back together, that the tip is centered.

I made this yesterday, since no one else seems to make one and I need one.
A quality metric rule mated to an 1"x36"x1/8" aluminum angle.
Tube marking and cutting slots will never be the same!
I used the ultra-thin double sided tape that I use to put shrink plastic on my windows in the Winter. That way it can be removed if necessary, or I can re-think the whole thing if I need to change it.
I could not find any Incra Angled Rules in metric of suitable length, since they don't make one.

Here's a jig I made for slotting centering rings up to 6" diameter. Almost all the parts are Baltic Birch plywood and the tops of the slide rails are lubed with regular paraffin canning wax (the hard white/clear stuff).

I have cut up to 3/4" Baltic Birch but its take it slow process or the blades get hot and break. 1/2" material is fairly common also a bit slow. I use spiral cut blades.
