木工材料比標準佈線更大

標準的5/32英寸餅乾似乎較薄,可以牢固地接合較厚的木板。Feastool似乎是完美的工具,但是這對我的體積來說是高價位。我有一個1/4英寸的切槽刀路由器,但是,如果可能的話,最好不要製作自定義餅乾。

有沒有製造商製造的圓形或比我所缺少的標準木工餅乾(1/4英寸或更厚)更粗或更粗?

似乎MLCS與#H-9距離最近,根據他們的支持,#11,餅乾或Feastool的6mm榫不再可用。

旁注:在編寫此問題時,意識到將兩個餅乾切成彼此平行也是可以的。

My understanding is a biscuit's primary purpose is to hold the timber perfectly in position as the glue dries which often takes days even with glue that "dries" in minutes.

For example I have a tube of "instant" liquid nails that advertises a strong hold after just 2 seconds but requires a full week to reach it's full strength potential.

Any movement during that week massively reduces the strength of the glue bond. I've even seen joints separate entirely due to expansion/contraction of the timber as it adjusts to the ambient humidity.

A biscuit only needs to be strong enough to hold the timber in position for an hour or a few days after which the glue alone will be strong enough to hold the joint together (dowels or screws or brad nails or clamps or a spline joint would be just as effective, but biscuits can be quicker/easier than any of those).

Many glues are so strong even with a sledge hammer you'll struggle to separate an edge joint. The timber will splinter and snap while the joint holds strong.

These things obviously vary depending on the timber and glue being used as well as surface preparation (sanding/cleaning/etc). If you're worried your joint won't be strong enough, test it out with a scrap piece of timber. If it doesn't work, I suspect you're doing something else wrong (for example some biscuit jointers cut the slot too big the biscuit should need a light taps with a hammer force it into the hole).
