Pete,
Not sure why but I have always found that 275rpm seems to work very well (mainly because it's the slowest my pillar drill will go
I never really found that cobalt drill have an issue with going through ti but breaking out through the other side is a different issue.
Maybe it's the 10mm holes i've been doing in 4mm ti that causes it but i have found that the drilling part is quite easy intil the point of the drill breaks through and then it can have a tendancy to snatch on the burrs on the edge of the hole. When this happens I found it's best to give up on the slow speeds cos the burrs just need to be ripped off so running it at full speed helps it break through.

When I was doing heavyweights, I used to bend polycarb (Lexan) a lot. The tricky bit is to heat it slowly. If you get bubbles, it will be brittle when it goes cold. You have to heat slowly and gently - a slow oven over a wood former is good for ants.Andrew_Hibberd wrote:A really nice piece of work with the Ti. Just out of interest has anyone tried bending 2mm Lexan or HDPE, either hot (oven or line bender) or cold?
Re: Ti bending, I did the bends for Terrior and it was quite hard - partly because it was winter - the difficult part is keeping it at cherry red while making the bend and then gradually reducing the heat. I did make a severe bend at the hinge, which broke and I had to do it again...so the flipper is actually shorter than I planned.
Thinking of using Ti for new Pants, so if anyone has any ideas of sources....

I'm not sure on a source for thin stuff, however you may want to ask Simon, he had a sizeable sheet of 0.5mm Ti, and I still have a sheet of the Grade 5 1mm stuff, and some 1.2mm unknown grade that I got given by Craig from The Saint (HW axlebot), his son Zak had a Pants kit robot thats bright orange and he called it Smarty Pants

I noticed the other day that Blacks (camping/outdoor pursuits shop) sell titanium tent pegs, some made from angle plate, others made from wire/rod.
May be of use to someone...

(I'm sure they were cheaper in-store)

Found this the other day. May be a more reliable supply than Ebay.
325mm X 120mm X 1mm.
It doesn't say what grade it is but if it's for car mods presumably it isn't grade 5! They also have rod on the site.
