Can anyone suggest a similar off the shelf low cost alternative to this adhesive ?https://files.engineering.com/getfile.aspx?folder=44fad0e1-e653-4179-8f41-297bec766cc5&file=000000000002320563_000000497843_MSDS_UT_US_EN.PDF

What would be a suitable flexible coupling type for a 10 hp Diesel engine to a 6kva alternator at 3000 rpm , both having 25 mm keyed shafts ?

I found this solution to what i need, if I beef up the design , remove the jack and fit a longer manual lever it should press out a good solid brick of fuel at a good rate. https://youtu.be/c_UuVV7fhMc?si=93vFj415D1JNB_VS

The design of the press would be effort and time saving if the product could be formed in one pull of a lever, the problem with a hydraulic jack is pumping the thing up each time, which makes producing these on a large scale very time consuming . A fly press is an option but big ones cost a...

I'm thinking about the design of a hand press to produce fuel logs from wet cardboard slurry and I would like to acheive it by using a long lever or series of levers, no jacks ot motors, can anyone give me any tips on design of such mechanisms and how to acheive the maximum pressing power ?

I am putting PIR sheet insulation in a steel cabin on a boat, this cabin gets very hot in summer, will adding a reflective foil layer between the insulation and the steel cabin sides and roof keep the cabin cooler in summer ? The foil layer on the insulation will be facing inside the cabin ...

I need to insulate an area behind a woodstove on a houseboat , the thickness is limited to 40 mm and behind it is 4mm steel cabin side, ideally this should be 100mm of Rockwool but there is no space, what materiel will give me the best insulation performance and also be fire proof ?

Why would increasing the radiant heat transfer from the fuel to the stove body be better than the other methods of heat transfer to the stove body?

Recently a product has come on the market that consists of a cage to hold coal inside a solid fuel burning stove in a vertical stack instead of laying piled up on the great, the inventor claims this increases radiant heat, buyers are reporting they are saving significant amounts of fuel using...

As i said the HX would need to be a bigger area than the standard ducting coming off the engine to make up for the restriction.

Tis an air cooled engine, there is no water involved, all the heat is blown away up a ducting.

can anyone tell me what the restriction in airflow is through any types of air to water heat exchanger ? My application is recovering 80 degree C hot air flow from an air cooled engine to heat water. Maybe this type of heat exchanger ?

The plus side is the fuel consumption to the engine is only 1 liter an hour, which i want to get near to 80 oC using the hot air stream.

i have an 3 cylinder air cooled diesel engine, with a vertical hot air duct, 650 cm2, @ 80 degrees C max , i want to pre heat vegetable oil fuel from this air stream, what kind of heat exchanger would suit this purpose ? naturally the air flow cannot be interupted much, or the engine will...
