There's a difference between having an opinion about a product and materially misrepresenting it. We're certainly open to criticism. I have no desire to argue with you. After all, we're practically neighbors except that you support the Packers :) The Nomex piece on the bottom is larger than...

You essentially said that this product won't work and will "for sure" burn the chute. Those are strong words coming from you, especially when that's not the situation and when you haven't even tried the product. Opinions are one thing, but to basically say that the product won't fulfill its...

There is indeed an appropriate amount of overlap in the petals once it's slid into the body tube. It protects the parachute extremely well. Tim has some good photos on his website https://www.apogeerockets.com/Building-Supplies/Parachute-Protection/Cloth/Dino-Chutes-3in-Petal-Protector showing...

I'm curious if your testing ended up putting something out of tolerance such as the hole that the pin gets inserted into. In normal operation the force isn't necessarily completely linear like it is when you pull on the pin with your hand. I can see where testing it like you did could simply be...

I too have a Robinair pump, but it's 3cfm. I also do vacuforming, so at least 3cfm is needed to pull down a part quickly before the plastic firms up again. You can get used Robinair vacuum pumps on EBay, usually for less than $150. Unless they've changed since I bought mine, the pumps use an...

If you already have a granite plate then just use a surface gage on your granite plate to draw precise parallel lines. https://www.mini-lathe.com/Mini_mill/Accessories/Layout/surface_gage_.jpg

Talcum powder on the new rubber band helps substantially on getting it through the tether point.

Our kids used two CRs on a 60" chute for SLI. Their parachute fabric was very thin and slippery. I think one CR would have created problems with the fabric being so slippery. When they hooked everything up with one CR, it was obvious that it was really squishing the fabric together in the...

Our kids used our 36" Guide Chute on their 20 pound SLI rocket and got descent rates around 80fps. It kept all the recovery gear nice in line. I think rockets weighing less than that would probably bring the descent rate to a more reasonable level. In any event, the Guide Chute works with...

Numerous options- the simplest would be to simply clean the inside of the body tube and epoxy your new cord in place. Paracord is rather thick, and if you went with that method then I'd only use the outer sheath of the cord by removing the inside. That would allow it to lay flat for gluing...

Electric motors have gotten to be very expensive. I've purchased a fair amount of used motorized tools from Craigslist simply to have the motor. You might find it cheaper to buy a whole new unit and just take the motor from it and swap it into your old unit. I do that with our ceiling exhaust...

I installed about 90% of my Mitsubishi system and absolutely love its performance. I had built a new workshop and did plenty of internal wall bracing so that the outside support brackets were nice and solid. I had everything ready to go for an HVAC guy and did my own shut off box and wiring. He...

I was thinking of what to recommend to you and forgot that I have a bike for sale that sounds like what you might be looking for. Seriously- I had it off the market during vacation and forgot to put it back for sale. It's a Trek Domane which is a racing bike with a more relaxed fit. So it's a...

Not having updates really affects TARC and SLI where teams buy dozens of motors for competition purposes where changing motors at a later date really messes things up. Sport flying is one thing, but competitions that go on for many months need reliable motor supplies, and not having updates...

We have a protector pouch that many hundreds of your fellow rocketeers are already using. Available in two colors and John sells them on his site too. https://www.dinochutes.com/Chute-Release-protector-ChtRlnomex.htm

HAAS I really popular among the machinists in my area. A lot of machine shops are going out of business and you can get some very good deals on Craigslist. I'm talking high-end equipment- $20-30K being sold a deep discounts. A local machinist I used passed away last year and his family sold his...

I use FNF which doesn't really penetrate the surface, so I'm able to fill and sand the fins prior to gluing then on. However, if you use some sort of dope that penetrates the surface pretty well then I'd glue the fins on first. I'd be concerned about the glue not soaking into a fin that has...

I've bought various tools from them over the years. They have an interesting selection of precise tools that are useful for rocketry. I've bought a few of their guitar making tools such as their various hole cutting jigs that can be used with small routers and used them for making centering...

Just remember that if your chute slips out of the rubber band that it may seem that it got released prematurely. That's because the CR will still function normally and release the rubber band when it hits its set altitude. Granted, it may not always release if there's no pressure on it, but the...

Our kids used the CR for their SLI rocket. We own 4 of them because they were using two at a time for their rocket and we needed a backup set. Anyway, we always try to note where the split section of the small split ring ends up in relation to the rubber band. It's a nicely made ring, but I...
