I upgraded my FoxAlien Masuter Pro with a compact router to replace the underpowered 60W spindle motor that it came with. The only issue was, the router only came with a 3/8” and 1/4” collets which was fine for my 1/4” shaft bits but not my 1/8” shaft bits. And there wasn’t an option to purchase a 1/8” collet for that router. I saw these 1/4” to 1/8” adapters to use with my 1/4” collet and was hoping they would work. Well I must say, after I did a 30 minute carve, not only did they work but held the 1/8” shaft bit tight and ran true. No noticeable wobble and the carve came out perfect! I highly recommend these adapters if your compact router doesn’t have an 1/8” collet.
