How many parts of model engineer lister 6/1 plans been published, I have first 16 parts,Anyone willing to sell / send me missing issues pdfs ? thanks, Umut

We discussed glass fiber , wood , carbon fiber , carbon fiber powder for engine casing and parts making. Now last gun is the steel fibers which comes in 3 cms and 3 mms long variants , We put in epoxy and there is graphite powders inside also Does it make as good as or better than aluminum...

Thank you, abby. I mean with roving , textile. Thank you for your informative post.

In Istanbul, there are two options for making fiber reinforced plastic making with carbon fiber or with carbon fiber powder. Carbon fiber is ultra expensive and fragile in roving form. Second option , kilograms of carbon fiber powder is abundant and ultra cheap. I want to make a casing for...

My goal would be lower the costs , skip the expensive technology. I know carbon fiber is a good material but it cant compete with chinese engine prices. I am thinking epoxy , glass fiber and carbon fiber powder i kilograms of carbon fiber powder is ultra cheap. I think I can order a...

I think 30-35 years ago , someone at usa proved that carbon epoxy engine casing was lightweight and strong , heat resistant and works. He made many nascar like race engines and they completed the race without malfunction. Thats good but carbon is ultra expensive here and the epoxy. And only...

wow , wooden parts...wow. I read an article at science magazine this year and it was about a wood which is bulletproof and near to steel titanium specs. Scientists boils the wood block in salt heavy water and when the wood is soft , press it %500. the vains turns in to micro nano tubes and...

I am thinking also put thick cast iron liners to cut the flame concrete relation.

Thank you , I think there might be some problems , please correct me, reactive concrete loses its compressive strenght to 1/10 at 1000 celcius. bending strenght is 1/10 of the compressive strenght. I will try to find cooling and heating cycle strenght also. I read , at 1960s , americans...

Hello there, I have read tons of scientific papers on bunker concretes which made for heaviest air raid. If you read reactive concrete at google , you impress with their strenght. For example , they make an wall with reactive concrete and explode c4 nearby and concrete as it is. Well , I am...
