New look of M20A1 Bazooka

Here is the proceeding of 1/6 scale U.S Bazooka M20A1 modify；First thanks to my friend “Chung”who provided correct information of Korea War of M20A1 version．The kit is “Famous World Weapon of Collection”products which is injection run 1/6 scale kit that there are some mistake that needs to be correct．Now I’m start to convert rear nozzle component first‧
這把3.5英吋“超級巴祖卡”是目前市面上唯一的選擇，感謝chung兄的資料協助而能夠修改這支巴祖卡錯誤的地方．這支超級巴祖卡是在韓戰期間被開發出來而它則是專門用來對付北韓軍的T-34/85坦克，事實也說明這超級巴祖卡的威力．





Step 1﹒Chop the original rear nozzle off，clean through the Bazooka tube；Original have been block at both side．
首先將原來的後噴嘴切除並讓火箭砲身完全透空，因為原本是前、後封閉的．








Step 2．Used FIRM sculpt the rear nozzle shape then go through shape modeling via plastic plate because lack of vacuum machine help that cause fail result．The clay can’t take the heat that will cause out of shape．
第二，我以FIRM塑出後噴嘴的形狀然後用膠版烤熱直接壓模；而這是失敗的範例因為沒有真空壓縮機的輔助而無法將正確的形狀壓出．另一個缺點就是FIRM遇熱時會稍稍融化而形狀走樣．





Step 3． I used Supersculpey as mold then cast a resin rear nozzle；I had add the tube in the middle of cast for vacuum air suck out when the shape has make．I had also add another three hole at the curve parts that this will help the curve shape goes perfectly．
第三，以美國油土做外模接著灌注入Hei-cast成後噴嘴的模型；再將美國油土的外模拆毀．注意在中間的部份以空心管固定住；還有噴嘴的彎折處也鑽出3個小洞而這些洞是讓真空的空氣藉著氣孔而壓出正確的形狀來．
