thread cutting using a router

[bthere]

I also soak the dowel stock in dilute Danish Oil just before cutting the threads. This lubricates the cutting and penetrates the newly cut threads. I think the oil hardens the threads.

That's a great idea. I never thought of it.

hey guys

sorry for the delay in posting i have to many irons in the fire, i've hit a stubling block in my progress

the insert has proved to be very difficult to produce a clean usable piece
to cut the external threads
i figured it would be pretty easy to make the insert using the 1 1/4" hdpe rod
step 1 cut to length 2"
step 2 drill out 1" dia hole 1" deep
step 3 finish drilling 7/8"
step 4 tap with 1" tap
step 5 mark and drill a 5/16" hole for the router bit

the taps dont cut hdpe very good

i will update as i figure it out
i have another neighbor that has a full machine shop that i have been tring to catch for about 2 weeks now to see if he could just mill the inserts out for me

thanks blame

hey guys

well i made my first threaded dowel tonight

what i did was just tap a pc of hedge insted of using the HDPE rod then on my old lathe i made a 1" dowel out of hedge also (hedge aka osage orange)
i have a pic but cant upload it becouse my youngest son took off with the cord for my computer
i'll try to upload new pics tommorrow when the LOML finds the cable

i still have some work to do on it the first 1/2" of threads are not being cut right
more to come

Its hard to tell, and I could be wrong, but your taps look like thread restorer taps, not thread cutting taps. Thread restorer taps are used to salvage damaged threads that have been cut previously. Cutting threads with the restorer taps would be difficult and give poor results in almost any material.

they were listed as bottem taps but there china made and are soft steal
just cutting threads in acouple of the pcs of hedge with them they are already dull and losing there shape atleast for the 1" tap

i'm saving up to buy the beall set of taps which cost 30 bucks for the 1" tap
but you pay for what you get and the china taps suck LOL should of known better then to buy them

sorry guys here is the pic of the first threads i cut using the router jig

this was a home made dowel i made out of hedge on my old lathe it was 15/16" in dia
cut really fast took about 15 secs to cut the threads about 4"

but as you can see in the pic the first course of threads where not cut right i dont know if it was me or the way the jig is taped
