Principles

Using the principles of levers, fulcrums, turning moments, a simple lightweight timber frame and brute strength I managed to get the solar hot water panels onto the shed roof.

By the time the relocation was completed it was starting to get hot and I decided to go to the plumbing wholesaler where I intended to purchase the rubber ring washers used as seals when the panels connect.

The storeman said “Rheem Solar Hot Water System!” and I agreed, guessing he was right!  He returned with the two washers and I started fingering the 50c coin in my pocket.

. 

He looked in the computer system and announced $9.66.  I was so damned stunned by the price I actually paid!!! What I should have done is gone to the chemist and bought two condoms and then cutting their ends off.  This is based on the assumptions condoms are cheaper than $4.83 each.

I’ll have to include the location of these rubber washers in my will.  That will enable the children to recover and sell them as part of their inheritance.

A courier van appeared mid morning delivering the small (and cheap) 12V water pump Jan had ordered from eBay.

There were a further two courier delivers today.  The first was a long, well wrapped package which I immediately guessed contained the aluminium extrusion for the DIY router fence.

I immediately realised I’d made an error.  The ‘T’ profile in the aluminium is far smaller than I had anticipated and will require additional modifications to use the profile.

The second delivery was the adjustable mounting brackets for the router fence.  They were al;so ordered from China.

In the afternoon I drove to Timbercon in south Perth and purchased a dust extraction hood for the fence.  The price at $8 was cheaper than China.

I have enough components to make a start on the fence.

Testing the layout

There was a problem with the size of the connection between the hood and the flexible hose.

However I hunted through the box of “stuff that might be useful someday” and found two pvc pipe fitting surplus from the swimming pool installation.

It works

The project will continue tomorrow.
