Lucite stems, Tenons.
Lucite stems, Tenons.
I was wondering if anyone makes full lucite stems. Everything I read seems to suggest that derlin is used for the tenon on a lucite stem. Why is this and is it really necessary?

Re: Lucite stems, Tenons.
Several a day, most days. Integral tenons on all but special requests and some repairs. Nothing tricky about Lucite except the suddenness os its "heat response." You must stay aware of---and stay on top of (control)---its temperature.Briarfox wrote:I was wondering if anyone makes full lucite stems.

What heating method are you using to bend stems?Briarfox wrote:Whats the best way to control it's temperature? Just take it slow? Do you ever use any oil to help keep it cool?
My experience is that a heat gun works best. You don't need cooling fluid, just control the amount of heat applied.
If you're referring to drilling, don't use high speed.

I was referring to cutting operations, not bending, btw.Briarfox wrote:Whats the best way to control it's temperature? Just take it slow? Do you ever use any oil to help keep it cool?
To keep cool while cutting, alcohol works well. It evaporates quickly. I also use a touch of white mineral oil (the sort designed for cutting, not lubricating) from time to time. Slow and steady is also part of it (though what "slow" means to different people leaves the door open to later confusion.)
You're a board regular so probably know how I make stems is not typical of carvers, though.
My main reason for controlling temps isn't heat destruction---that never happens when things are set up and used right---but dimensional stability. I like cutting tenons that are a perfect "hydraulic feeling" fit off the machine, and don't need further adjustment. The only way to get it is keeping the material being cut a constant temperature.

Not as easy as it sounds, though. Lucite especially can be treacherous. For tricky shapes, sometimes water pans and so forth are necessary. Think dodging and burning in a photo darkroom.Frank wrote: What heating method are you using to bend stems?
