Re: Hard Time's build diary

Don't forget to have the jigsaw running at a low speed. This will reduce (although not eradicate) heat generated during the cutting process. I find a coarse blade (bigger teeth) to be best, as has been mentioned. Don't force the jigsaw through the material, just take it at a steady pace and it will be fine. It should fly through 6mm HDPE and will also be pretty quick through the 15mm stuff.

I wouldn't bother too much with coolant for it; if you keep the speed down (maybe setting number 3, if your jigsaw goes from 1 to 6) and take it steady it will cut without issue.

Got a bench saw a few days ago... Tested wood on it and it cut fine blah blah blah.
Made the outer frame cutting the base and few little twiddly bits got some screws.

Re: Hard Time's build diary

forgot to add I mucked up the back of the robot; once I had finished cutting I stupidly left the saw still spinning and I pulled one end of the plastic away pushing the other end into the spinning sawblade so there is a big curve one end.

Re: Hard Time's build diary

did you have enough plastic to rebuild it

Re: Hard Time's build diary

I dont have any left over, but luckily I'm cutting the bad end off because it is too big.

Re: Hard Time's build diary

Cut the plastic last night, trimming it down to size today.

Re: Hard Time's build diary

Made a jig to make it all to size uploading pics of what it looks like so far.
Ordered 4 100mm blue wheels, hopefully coming today.Where is the best placed to get shafts and bearings?
