Air planishing hammer and foot valve

[Wendelspanswick]

Thought I would share my latest project that I have just finished, a 600mm throat air planisher using a cheap air chisel.

I used 50mm box for the frame, 40mm box with a length of 1" water pipe rammed inside as the lower die carrier and 4 pieces of 50mm by 10mm flat as the lower die carrier housing.

A length of M24 all thread is used as the adjuster.

Top die is a flush set rivet head from ebay, bottom dies I machined on the lathe apart from the flat one which is a brake disc caliper piston which fits over the die holder.

I am especially chuffed with my home made air foot valve.

I used a £3 blow gun as the air control, a length of 3/8th nylon tubing screws into the end of it.

I then built a frame around it using 40*5mm flat, with a piece of 3mm plate as the top hinged with a 90mm butt hinge.

Works a treat.

Cool. Homemade foot valve especially (kicking myself for never having thought of something like that!)

Like the foot valve.

I made one using a washing machine valve and footswitch, but that needed mains.

Ditto with the valve idea, very simple.

What are you making/using it for?

This is a foot valve my Dad made years ago for his home made sand blast cabinet. It uses a gas shut off valve with the lever modified into a pedal with a return spring. It works great because you can vary the pressure depending on how hard you press like a throttle rather than just on/of like the Gyson units.

Cracking idea, that's why I chose the blow gun as you can vary the force of the air chisel rather than all or nothing.

Where did you get the hammer head for the air chisel? cant find a similar one anywhere!

 

[Wendelspanswick]

Got mine from ebay, what you need to search for is a "flush set rivet head".

The one above is similar to the one I bought, but mine had a 0.5" shank so I drilled out the Chisel body to match.
Most cheap chisels use a 0.401" shank.

Loving the foot switch i made myself a planshier and was extreamly lucky just 2 weeks after finishing it i was rumaging round my local scrappy and looking in a fileing cabanit that had come from a well knowen air craft maker and low and behold look what i found

the ones on m20 thred are my anvles made up with hard face ark rods and then ground with a die grinder in the tool post on my lathe and then matched to the hammers with grinding paste
