I have an MDF timber box (describing it simply) that has a 200mm. hole cut out the bottom..The bottom panel thickness is 25mm.
I want to increase the hole to 250mm. in diam. The internal box base is approx. 300x300.The depth of the box is 150mm..
Normally a simple enough job, but in this instance I can only reach the hole by going into the box because it's a part of a larger construction..
There's not enough room inside the box to use a router or jigsaw, so any ideas what sort of cutting tool I can use..
What about a reciprocating saw or multi-tool with a timber attachment? Otherwise you could try a handsaw cutting multiple cuts from the 200 to the 250 mark and knocking out with a hammer. Tidy the larger hole with sandpaper.
This is the unit in question..The dark angle brackets are only there for support during construction..
Should fit in with room to spare, from memory it is painfuly slow though.
