OK Gentlemen
I made an attempt .that perhaps someone can have use for.
This is so to speak a " prototype " on pictures
Perhaps a couple of Whacks with a sledge hammer would help..
And a few more spacers. Paint ..
Made it yesterday , and think it is above expectations so far.
It is low budget and so far dont need to weld. Even though i have that possibility not everyone have it ..
The bottom is from some sort of an armchair. -- pulled it out from a container., dumpster.
That is perhaps the most useful idea in this. The rest is not that complicated finding the other iron parts.
I think any barstool or even better Barbershop chair with pedals and adjustment possibilities would
be excellent. ( OK that might cost a bit )
The blue ones , from some sort of angle bracket for putting up shelves in a garage or workshop.
Could also be a bit thicker
The galvanized ones I do believe are used in Construction ..Building Wooden houses
for connecting Wooden beams
bought a set on a flea market for peanuts. Those are strong.
( I live in Europe Sweden , not sure the availability in USA , so if the English is weird i apologize
so please look at the pictures ) .
Its a bit on the weak side. The plate on the top of the chair is 5 mm about 1/5 inch
Thicker would not hurt . On the other hand these chairs are made to also carry
people above 200 pounds .And the engine in total dont weigh that much.
It rotates around a vertical axle. Not sure if that is good or bad. But I found it useful when cleaning.
Turning helps to get light in.
I dont believe it would flex to much depending .What job one does.
It can be on top of the workbench or on the ground.
There is the possibility to reinforce The bolts are long enough and Welding is Possible.
I also use these type of undercarriages for making a toolplank.
I often do work outside .. With the tools on a movable plank I save time and walking
Had a transmission chain breakage ..or more correct the joint .. It smashed into the seal holding place .. Thats why i am in this situation.
So that is a recommendation. If in doubt replace the chain
