It's not much the overall tq I was concerned with, but the teeth the tq is delivered too. If you Google image search "ar15 barrel nut", you will see the "teeth" the wrench engages. If people belive 7075 is adequate, I'll run with it as 7075 is among the most common aluminum in the firearms...
Use will be for a barrel nut for a savage scout rifle and an ar15. The AR nut has a series of teeth around it that a barrel wrench engages and deformation from repeated installs or removals is a concern. Reason, to save weight. This is just a pet project. Material sciences interest me but are...
Looking to make some parts (nuts, about 1.5" diameter with a 1.25" bore) that will be torqued to about 30 ftlbs several times. Is 7075 adequate or is a stronger alloy available?
Thanks.
The other material is Kevlar. Yes, it is a wet clutch in a race bike. Weight reduction in a bike is often the best bang for the buck in gaining performance vs increasing engine output. Durability of the plates is why I was warned away from the Aluminum plates all together, they were supposedly...
Thanks to both of you. Yes, the design is a little unorthodox but it seems to work without any real issue even in an un-coated condition. I am thinking ahead though and want to minimize downtime for maintenance or repair.
I am going to look into those rings more and see if they may be the key.
I have recently found a company that makes high performance clutch plates for my motorcycle that are made out of Ti instead of the traditional steel. I asked a respected engine builder and tuner if he had ever used or seen them before and he had not.
When asked his opinion/thoughts on them he...
I have several alloy shafts that will see road use. They will carry loads but indirectly through bearings on the shaft. While the load will rotate on the bearings, the bearings themselves are still able to rotate on the shaft.
What would be suggested as a good low friction, anti-galling/wear...
A search came up with this company. Going to contact them to see if they have done anything with motorcycles.
Hopefully I hear back from them.
Would it make any difference if the axle itself was stationary? Unlike a car, a bike axle does not rotate and the assembly that does rotates on a...
Israelkk, I wouldn't even know where to begin to do that as this is not my field of expertise. If the the Ti axles are appropriate, can one go off the various info from those for strength etc and then design a part using another material that matches the critical properties?
I am limited in overall diameter but can go thicker as far as wall thickness. I don't want to go to thick though or I would lose the advantage of being light weight. Thankfully, the pieces are not very long and have little weight focused near the center, most all is at the ends. I will post pics...
I have an Italian sportbike that I would like to have custom axles made for. OEM ones are steel, grade unknown. I can have custom machined Ti axles and swing arm pivot made for roughly $1400. They would come from a highly regarded company that makes many products for motorcycles in Ti. They use...
They have a CAD design package you can download and use to design things in 3D and then get a quote from them to build them from many types of material. I had the program a long time ago but lost it in a catastrophic PC crash and can't remember the name of the website or company name for the...
Appreciate the input so far from everyone. This will not be put for for a military contract, it will be a reproduction of a stock that is no longer available. I think I may have found someone who can make molds for me after I send the original out to be laser scanned and reverse engineered. Not...
No recoil pad. Won't be needed as it is only a 223/5.56mm. Are you talking about a foam core then expoxied with an overlayment of a kevlar/fiberglass type cloth? They make remote control airplane wings with that technique.... Probably doable but slow to produce. Definately would be stong and...
I want to make a prototype rifle stock. The material needs to be available in matte black or dyeable to black, dimenionally stable, strong, and machinable.
Delrin, Torlon????? Any others or better suited types? The actual stock will be about 1 ft long and about 1 1/4" wide.
Also, what are some...
Thanks for the input guys! I love this place. ;) I found some places that can reverse engineer it by taking 3d Laser scans and creating a cad file that I can send out for bids. Just gotta see what that will cost... Also looking into MFGquote.com where I can send out for mult RFQs.
You guys...
Thanks for the input!
Where do I go to send out RFQs? I am all new to this stuff but not to the firearms area. How do I find good small shops that are reputable? I have found plenty of bigger shops on-line. Where would I have a drawing of the part made?
As one part would be considered the...
Well, I wish I had a pick I could put up. I want to have a firearm reciever 3D laser scanned and put into a CNC readable file. It is for a rifle who's patent expired a couple of years ago. It is made of cast alluminum and has a deep internal cavity and shapes that must be be exact.
There would...
