Featherweight pneumatic threads








Paypal fees calculator

Something useful i found today was this paypal fees estimator at https://www.clothnappytree.com/ppcalculator/


It is only an estimator but is a useful tool to have access to when sending invoices or requesting money through Paypal for goods and not through friends and family payments.


Featherweight motor mounts specific for locking and firmly fixing in the new style Argos £20 hand battery drill.

Although ok, I need to change the bolts used to countersunk and adjust some tollerence, or clean print the crevices to fit better. My new design has these in, so when I get printing I can test fit and see what they are like.

This initial design does lock in the motor tightly, so I’m pleased.


Now Robot Wars has made it to a new 2nd series, Series 9, I want to get back into the big bots…

However as I have just bought a house, I have priorities…


I have a lot of stuff that would suit a featherweight, including all parts to make a pneumatic system and drive Inc batteries. Out of this, all I am missing is a storage tank for gas, refilling valve and wheels.

I do have some gold feather 12v motors somewhere but I will use drill motors instead. I have 1 old drill at work, and I’m sure I can find another!

I have wheels from B&Q but I will probably need other tyre styles for traction.

I have scrap metal to make a frame and chassis,  as well as potential access to cheap armour materials on regular trips to scrap yards so…

All I need is a £20 paintball gas tank and additional fittings, tyres, and a second drill motor.

My initial drawings have led me to build my first iteration design of my Robot Wars robot, so will look at this route with a pneumatic flipper.
