I made tank mounting brackets. According to the textbook they were made by folding thin sheet metal. However I did not like this way, and cut them out from 5mm thick brass plate. At first I cut a slotted hole.
サイドタンク取付ブラケットを作ります。教科書では薄板を曲げて作ることになってますが、私の好みではないので厚板から削り出すことにしました。まずは、5mmの真鍮板にフライスで長穴を掘ります。

I turned the work by 90 degree and cut bulges and mounting holes.
切断後、90°まわして出っ張りを削り出し、台枠への取り付け穴を開けます。

Unwanted parts were cut out by slotting saw.

The work was separated to two.

The brackets were finished.
ブラケットが出来上がりました。

There were mounted at the bottom of the tanks.
タンクの裏に取り付けます。

Mounting holes on the frame were drilled by job.
台枠の取り付け穴は現物合わせで開けました。
|
|
Tanks were mounted.
サイドタンクはこのように取り付けられます。

A problem was revealed. I made a miss-calculation and the spacing of the tanks was not even. It was narrower in front by 1mm.
ここで問題発覚。どこで計算を間違えたんだか、タンクの取り付けが平行になってない。前の方が1mm程狭い。

|
So I had to make mounting holes larger and filed out back plate a bit.
しかたがないのでタンクの裏板を削り、取り付け穴を長穴にした。
