Beside soldering iron and hot-melt gun are the top miller the most important tools of the self-builder. With it he can straighten edges, attach curvatures or shadow joints and produce above all perfectly circular holes for the chassis. If he wants to use, besides, however, smaller loudspeakers with less than 15 cm of diameter, he is fast sent up without laborious and time-consuming stencil pieces, because the provided tool of a circle does not admit smaller radii. Now there are on the Internet legions of sides which offer easy solutions for method ale to Do-it-yourself-milling circle, nevertheless, I present at this point another which does not need the world maybe which was invented for it, however, by myself, the Intertechnik milling circle.
This are the ingredients which I bought in the practical person's property market: a 1-metre-long aluminium strip to which ordinarily by means of suitable hooks tools are suspended and a packet with short and longer threads and nuts which usefulness avoids my knowledge. Both delivered the company Alfer there. In the cash said the lady: eight euro and ninety cent, unfortunately the 20-percent discount was not valid in the week except animal food.
Some MDF-board I found in the cellar, they had the same thickness like the halved strip with 10 mm. I cut two to me in 4 x 13 and two in 3 x 13 cm, I screwed four long threads on the angular mother who fit exactly in the groove.
In the wide little boards I have bored with 2.5 cm of distance to the edge a few holes by which the threads fitted well through. The narrow little board served as a distance holder, then the plastic nuts were screwed on. Right "T" carries later the centering spike, hence, it is held by four screws. His 3-cm width correspond to the copy shell which has to go in the recess
The centring is stuck with lowered head in his bearer who screwed I then with glue and two screws under his holder.
I screwed two corners still as a fine feeling onto the end of the circle with which I milled now with a 10 mm of cutter head the smallest engraving possible with it which I measured out with 3 cm of radius.
From an old limb tape measure I took a limb and stuck it with metal glue so under the pushing that 3 are exactly readable. Now I can put for the 10th drill the radius with a look. The stuck on tongue pushes under the milling table up to the copy shell.
I have stuck a correction measure of bigger cutter heads in the end still under Centred. There I put half of the head difference and receive thus in the pushing again the radius with the topical drill. There are examples of use of the Intertechnik-milling circle soon at this theatre.
